+# agnoster's Theme - https://gist.github.com/3712874
+# A Powerline-inspired theme for ZSH
+#
+# # README
+#
+# In order for this theme to render correctly, you will need a
+# [Powerline-patched font](https://github.com/Lokaltog/powerline-fonts).
+# Make sure you have a recent version: the code points that Powerline
+# uses changed in 2012, and older versions will display incorrectly,
+# in confusing ways.
+#
+# In addition, I recommend the
+# [Solarized theme](https://github.com/altercation/solarized/) and, if you're
+# using it on Mac OS X, [iTerm 2](https://iterm2.com/) over Terminal.app -
+# it has significantly better color fidelity.
+#
+# If using with "light" variant of the Solarized color schema, set
+# SOLARIZED_THEME variable to "light". If you don't specify, we'll assume
+# you're using the "dark" variant.
+#
+# # Goals
+#
+# The aim of this theme is to only show you *relevant* information. Like most
+# prompts, it will only show git information when in a git working directory.
+# However, it goes a step further: everything from the current user and
+# hostname to whether the last call exited with an error to whether background
+# jobs are running in this shell will all be displayed automatically when
+# appropriate.
+
+### Segment drawing
+# A few utility functions to make it easy and re-usable to draw segmented prompts

+  # If this is not working for you, you probably have an old version of the
+  # Powerline-patched fonts installed. Download and install the new version.
+  # Do not submit PRs to change this unless you have reviewed the Powerline code point
+  # history and have new information.
+  # This is defined using a Unicode escape sequence so it is unambiguously readable, regardless of
+  # what font the user is viewing this source code in. Do not replace the

+#
+# Differences from Pure:
+#
+#   - Git:
+#     - `@c4d3ec2c` instead of something like `v1.4.0~11` when in detached HEAD state.
+#     - No automatic `git fetch` (the same as in Pure with `PURE_GIT_PULL=0`).
+#
+# Apart from the differences listed above, the replication of Pure prompt is exact. This includes
+# even the questionable parts. For example, just like in Pure, there is no indication of Git status
+# being stale; prompt symbol is the same in command, visual and overwrite vi modes; when prompt
+# doesn't fit on one line, it wraps around with no attempt to shorten it.
+#
+# If you like the general style of Pure but not particularly attached to all its quirks, type
+# `p10k configure` and pick "Lean" style. This will give you slick minimalist prompt while taking
+# advantage of Powerlevel10k features that aren't present in Pure.

+# Recommended font: Meslo Nerd Font patched for Powerlevel10k
+
+Gorgeous monospace font designed by Jim Lyles for Bitstream, customized by the same for Apple,
+further customized by André Berg, and finally patched by yours truly with customized scripts
+originally developed by Ryan L McIntyre of Nerd Fonts. Contains all glyphs and symbols that
+Powerlevel10k may need. Battle-tested in dozens of different terminals on all major operating
+systems.
+
+*FAQ*: [How was the recommended font created?](README.md#how-was-the-recommended-font-created)
+
+## Automatic font installation
+
+If you are using iTerm2 or Termux, `p10k configure` can install the recommended font for you.
+Simply answer `Yes` when asked whether to install *Meslo Nerd Font*.
+
+If you are using a different terminal, proceed with manual font installation. 👇
+
+## Manual font installation
+
+1. Download these four ttf files:
+   - [MesloLGS NF Regular.ttf](
+       https://github.com/romkatv/powerlevel10k-media/raw/master/MesloLGS%20NF%20Regular.ttf)
+   - [MesloLGS NF Bold.ttf](
+       https://github.com/romkatv/powerlevel10k-media/raw/master/MesloLGS%20NF%20Bold.ttf)
+   - [MesloLGS NF Italic.ttf](
+       https://github.com/romkatv/powerlevel10k-media/raw/master/MesloLGS%20NF%20Italic.ttf)
+   - [MesloLGS NF Bold Italic.ttf](
+       https://github.com/romkatv/powerlevel10k-media/raw/master/MesloLGS%20NF%20Bold%20Italic.ttf)
+1. Double-click on each file and click "Install". This will make `MesloLGS NF` font available to all
+   applications on your system.
+1. Configure your terminal to use this font:
+   - **iTerm2**: Type `p10k configure` and answer `Yes` when asked whether to install
+     *Meslo Nerd Font*. Alternatively, open *iTerm2 → Preferences → Profiles → Text* and set *Font* to
+     `MesloLGS NF`.
+   - **Apple Terminal**: Open *Terminal → Preferences → Profiles → Text*, click *Change* under *Font*
+     and select `MesloLGS NF` family.
+   - **Hyper**: Open *Hyper → Edit → Preferences* and change the value of `fontFamily` under
+     `module.exports.config` to `MesloLGS NF`.
+   - **Visual Studio Code**: Open *File → Preferences → Settings* (PC) or
+     *Code → Preferences → Settings* (Mac), enter `terminal.integrated.fontFamily` in the search box at
+     the top of *Settings* tab and set the value below to `MesloLGS NF`.
+     Consult [this screenshot](
+       https://raw.githubusercontent.com/romkatv/powerlevel10k-media/389133fb8c9a2347929a23702ce3039aacc46c3d/visual-studio-code-font-settings.jpg)
+     to see how it should look like or see [this issue](
+       https://github.com/romkatv/powerlevel10k/issues/671) for extra information.
+   - **GNOME Terminal** (the default Ubuntu terminal): Open *Terminal → Preferences* and click on the
+     selected profile under *Profiles*. Check *Custom font* under *Text Appearance* and select
+     `MesloLGS NF Regular`.
+   - **Konsole**: Open *Settings → Edit Current Profile → Appearance*, click *Select Font* and select
+     `MesloLGS NF Regular`.
+   - **Tilix**: Open *Tilix → Preferences* and click on the selected profile under *Profiles*. Check
+     *Custom font* under *Text Appearance* and select `MesloLGS NF Regular`.
+   - **Windows Console Host** (the old thing): Click the icon in the top left corner, then
+     *Properties → Font* and set *Font* to `MesloLGS NF`.
+   - **Windows Terminal** by Microsoft (the new thing): Open `settings.json` (<kbd>Ctrl+Shift+,</kbd>),
+     search for `fontFace` and set the value to `MesloLGS NF` for every profile. If you don't find
+     `fontFace`, add it under *profiles → defaults*. See [this settings file](
+       https://raw.githubusercontent.com/romkatv/dotfiles-public/aba0e6c4657d705ed6c344d700d659977385f25c/dotfiles/microsoft-terminal-settings.json)
+     for example.
+   - **IntelliJ** (and other IDEs by Jet Brains): Open *IDE → Edit → Preferences → Editor →
+     Color Scheme → Console Font*. Select *Use console font instead of the default* and set the font
+     name to `MesloLGS NF`.
+   - **Termux**: Type `p10k configure` and answer `Yes` when asked whether to install
+     *Meslo Nerd Font*.
+   - **Blink**: Type `config`, go to *Appearance*, tap *Add a new font*, tap *Open Gallery*, select
+     *MesloLGS NF.css*, tap *import* and type `exit` in the home view to reload the font.
+   - **Terminus**: Open *Settings → Appearance* and set *Font* to `MesloLGS NF`.
+   - **Terminator**: Open *Preferences* using the context menu. Under *Profiles* select the *General*
+     tab (should be selected already), uncheck *Use the system fixed width font* (if not already)
+     and select `MesloLGS NF Regular`. Exit the Preferences dialog by clicking *Close*.
+   - **Guake**: Right Click on an open terminal and open *Preferences*. Under *Appearance*
+     tab, uncheck *Use the system fixed width font* (if not already) and select `MesloLGS NF Regular`.
+     Exit the Preferences dialog by clicking *Close*.
+   - **MobaXterm**: Open *Settings* → *Configuration* → *Terminal* → (under *Terminal look and feel*)
+     and change *Font* to `MesloLGS NF`.
+   - **Asbrú Connection Manager**: Open *Preferences → Local Shell Options → Look and Feel*, enable
+     *Use these personal options* and change *Font:* under *Terminal UI* to `MesloLGS NF Regular`.
+     To change the font for the remote host connections, go to *Preferences → Terminal Options →
+     Look and Feel* and change *Font:* under *Terminal UI* to `MesloLGS NF Regular`.
+   - **WSLtty**: Right click on an open terminal and then on *Options*. In the *Text* section, under
+     *Font*, click *"Select..."* and set Font to `MesloLGS NF Regular`.
+   - **Yakuake**: Click *≡* → *Manage Profiles* → *New* → *Appearance*. Click *Choose* next to the
+     *Font* dropdown, select `MesloLGS NF` and click *OK*. Click *OK* to save the profile. Select the
+     new profile and click *Set as Default*.
+   - **Alacritty**: Create or open `~/.config/alacritty/alacritty.yml` and add the following section
+     to it:
+     ```yaml
+     font:
+       normal:
+         family: "MesloLGS NF"
+     ```
+    - **Kitty**: Create or open `~/.config/kitty/kitty.conf` and add the following line to it:
+      ```text
+      font_family MesloLGS NF
+      ```
+      Restart Kitty by closing all sessions and opening a new session.
+   - **WezTerm**: Create or open `$HOME/.config/wezterm/wezterm.lua` and add the following:
+     ```lua
+     local wezterm = require 'wezterm';
+     return {
+         font = wezterm.font("MesloLGS NF"),
+     }
+     ```
+     If the file already exists, only add the line with the font to the existing return.
+     Also add the first line if it is not already present.
+   - **urxvt**: Create or open `~/.Xresources` and add the following line to it:
+      ```text
+      URxvt.font: xft:MesloLGS NF:size=11
+      ```
+     You can adjust the font size to your preference. After changing the configuration use `xrdb ~/.Xresources` to reload the config.
+     The new config is applied for all new terminals.
+1. Run `p10k configure` to generate a new `~/.p10k.zsh`. The old config may work
+   incorrectly with the new font.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<https://www.gnu.org/licenses/why-not-lgpl.html>.

+**gitstatus** is a 10x faster alternative to `git status` and `git describe`. Its primary use
+case is to enable fast git prompt in interactive shells.
+
+Heavy lifting is done by **gitstatusd** -- a custom binary written in C++. It comes with Zsh and
+Bash bindings for integration with shell.

+## Using from Zsh
+
+The easiest way to take advantage of gitstatus from Zsh is to use a theme that's already integrated
+with it. For example, [Powerlevel10k](https://github.com/romkatv/powerlevel10k) is a flexible and
+fast theme with first-class gitstatus integration.
+
+![Powerlevel10k Zsh Theme](
+  https://raw.githubusercontent.com/romkatv/powerlevel10k-media/master/prompt-styles-high-contrast.png)
+
+For those who wish to use gitstatus without a theme, there is
+[gitstatus.prompt.zsh](gitstatus.prompt.zsh). Install it as follows:
+
+```zsh
+git clone --depth=1 https://github.com/romkatv/gitstatus.git ~/gitstatus
+echo 'source ~/gitstatus/gitstatus.prompt.zsh' >>! ~/.zshrc
+```
+

+
+```zsh
+git clone --depth=1 https://gitee.com/romkatv/gitstatus.git ~/gitstatus
+echo 'source ~/gitstatus/gitstatus.prompt.zsh' >>! ~/.zshrc
+```
+
+Alternatively, if you have Homebrew installed:
+
+```zsh
+brew install romkatv/gitstatus/gitstatus
+echo "source $(brew --prefix)/opt/gitstatus/gitstatus.prompt.zsh" >>! ~/.zshrc
+```
+
+(If you choose this option, replace `~/gitstatus` with `$(brew --prefix)/opt/gitstatus/gitstatus`
+in all code snippets below.)
+
+_Make sure to disable your current theme if you have one._
+
+This will give you a basic yet functional prompt with git status in it. It's
+[over 10x faster](#benchmarks) than any alternative that can give you comparable prompt. In order
+to customize it, set `PROMPT` and/or `RPROMPT` at the end of `~/.zshrc` after sourcing
+`gitstatus.prompt.zsh`. Insert `${GITSTATUS_PROMPT}` where you want git status to go. For example:
+
+```zsh
+source ~/gitstatus/gitstatus.prompt.zsh
+
+PROMPT='%~%# '               # left prompt: directory followed by %/# (normal/root)
+RPROMPT='$GITSTATUS_PROMPT'  # right prompt: git status
+```
+
+The expansion of `${GITSTATUS_PROMPT}` can contain the following bits:
+
+| segment     |  meaning                                              |
+|-------------|-------------------------------------------------------|
+| `master`    | current branch                                        |
+| `#v1`       | HEAD is tagged with `v1`; not shown when on a branch  |
+| `@5fc6fca4` | current commit; not shown when on a branch or tag     |
+| `⇣1`        | local branch is behind the remote by 1 commit         |
+| `⇡2`        | local branch is ahead of the remote by 2 commits      |
+| `⇠3`        | local branch is behind the push remote by 3 commits   |
+| `⇢4`        | local branch is ahead of the push remote by 4 commits |
+| `*5`        | there are 5 stashes                                   |
+| `merge`     | merge is in progress (could be some other action)     |
+| `~6`        | there are 6 merge conflicts                           |
+| `+7`        | there are 7 staged changes                            |
+| `!8`        | there are 8 unstaged changes                          |
+| `?9`        | there are 9 untracked files                           |
+
+`$GITSTATUS_PROMPT_LEN` tells you how long `$GITSTATUS_PROMPT` is when printed to the console.
+[gitstatus.prompt.zsh](gitstatus.prompt.zsh) has an example of using it to truncate the current
+directory.
+
+If you'd like to change the format of git status, or want to have greater control over the
+process of assembling `PROMPT`, you can copy and modify parts of
+[gitstatus.prompt.zsh](gitstatus.prompt.zsh) instead of sourcing the script. Your `~/.zshrc`
+might look something like this:
+
+```zsh
+source ~/gitstatus/gitstatus.plugin.zsh
+
+function my_set_prompt() {
+  PROMPT='%~%# '
+  RPROMPT=''
+
+  if gitstatus_query MY && [[ $VCS_STATUS_RESULT == ok-sync ]]; then
+    RPROMPT=${${VCS_STATUS_LOCAL_BRANCH:-@${VCS_STATUS_COMMIT}}//\%/%%}  # escape %
+    (( VCS_STATUS_NUM_STAGED    )) && RPROMPT+='+'
+    (( VCS_STATUS_NUM_UNSTAGED  )) && RPROMPT+='!'
+    (( VCS_STATUS_NUM_UNTRACKED )) && RPROMPT+='?'
+  fi
+
+  setopt no_prompt_{bang,subst} prompt_percent  # enable/disable correct prompt expansions
+}
+
+gitstatus_stop 'MY' && gitstatus_start -s -1 -u -1 -c -1 -d -1 'MY'
+autoload -Uz add-zsh-hook
+add-zsh-hook precmd my_set_prompt
+```
+
+This snippet is sourcing `gitstatus.plugin.zsh` rather than `gitstatus.prompt.zsh`. The former
+defines low-level bindings that communicate with gitstatusd over pipes. The latter is a simple
+script that uses these bindings to assemble git prompt.
+
+Unlike [Powerlevel10k](https://github.com/romkatv/powerlevel10k), code based on
+[gitstatus.prompt.zsh](gitstatus.prompt.zsh) is communicating with gitstatusd synchronously. This
+can make your prompt slow when working in a large git repository or on a slow machine. To avoid
+this problem, call `gitstatus_query` asynchronously as documented in
+[gitstatus.plugin.zsh](gitstatus.plugin.zsh). This can be quite challenging.
+
+## Using from Bash
+
+The easiest way to take advantage of gitstatus from Bash is via
+[gitstatus.prompt.sh](gitstatus.prompt.sh). Install it as follows:
+
+```bash
+git clone --depth=1 https://github.com/romkatv/gitstatus.git ~/gitstatus
+echo 'source ~/gitstatus/gitstatus.prompt.sh' >> ~/.bashrc
+```
+

+git clone --depth=1 https://gitee.com/romkatv/gitstatus.git ~/gitstatus
+echo 'source ~/gitstatus/gitstatus.prompt.sh' >> ~/.bashrc
+```
+
+Alternatively, if you have Homebrew installed:
+
+```zsh
+brew install romkatv/gitstatus/gitstatus
+echo "source $(brew --prefix)/opt/gitstatus/gitstatus.prompt.sh" >> ~/.bashrc
+```
+
+(If you choose this option, replace `~/gitstatus` with `$(brew --prefix)/opt/gitstatus/gitstatus`
+in all code snippets below.)
+
+This will give you a basic yet functional prompt with git status in it. It's
+[over 10x faster](#benchmarks) than any alternative that can give you comparable prompt.
+
+![Bash Prompt with GitStatus](
+  https://raw.githubusercontent.com/romkatv/gitstatus/1ac366952366d89980b3f3484f270b4fa5ae4293/bash-prompt.png)
+
+In order to customize your prompt, set `PS1` at the end of `~/.bashrc` after sourcing
+`gitstatus.prompt.sh`. Insert `${GITSTATUS_PROMPT}` where you want git status to go. For example:
+
+```bash
+source ~/gitstatus/gitstatus.prompt.sh
+
+PS1='\w ${GITSTATUS_PROMPT}\n\$ ' # directory followed by git status and $/# (normal/root)
+```
+
+The expansion of `${GITSTATUS_PROMPT}` can contain the following bits:
+

+| `?9`        | there are 9 untracked files                           |
+

+    else
+      PS1+=" @${VCS_STATUS_COMMIT//\\/\\\\}"       # escape backslash

+}
+
+gitstatus_stop && gitstatus_start
+PROMPT_COMMAND=my_set_prompt
+```
+
+This snippet is sourcing `gitstatus.plugin.sh` rather than `gitstatus.prompt.sh`. The former
+defines low-level bindings that communicate with gitstatusd over pipes. The latter is a simple
+script that uses these bindings to assemble git prompt.
+
+Note: Bash bindings, unlike Zsh bindings, don't support asynchronous calls.
+
+## Using from other shells
+
+If there are no gitstatusd bindings for your shell, you'll need to get your hands dirty.
+Use the existing bindings for inspiration; run `gitstatusd --help` or read the same thing in
+[options.cc](src/options.cc).
+
+## How it works
+
+gitstatusd reads requests from stdin and prints responses to stdout. Requests contain an ID and
+a directory. Responses contain the same ID and machine-readable git status for the directory.
+gitstatusd keeps some state in memory for the directories it has seen in order to serve future
+requests faster.
+
+[Zsh bindings](gitstatus.plugin.zsh) and [Bash bindings](gitstatus.plugin.sh) start gitstatusd in
+the background and communicate with it via pipes. Themes such as
+[Powerlevel10k](https://github.com/romkatv/powerlevel10k) use these bindings to put git status in
+`PROMPT`.
+
+Note that gitstatus cannot be used as a drop-in replacement for `git status` command as it doesn't
+produce output in the same format. It does perform the same computation though.
+
+## Benchmarks
+
+The following benchmark results were obtained on Intel i9-7900X running Ubuntu 18.04 in
+a clean [chromium](https://github.com/chromium/chromium) repository synced to `9394e49a`. The
+repository was checked out to an ext4 filesystem on M.2 SSD.
+
+Three functionally equivalent tools for computing git status were benchmarked:
+
+* `gitstatusd`
+* `git` with untracked cache enabled
+* `lg2` -- a demo/example executable from [libgit2](https://github.com/romkatv/libgit2) that
+  implements a subset of `git` functionality on top of libgit2 API; for the purposes of this
+  benchmark the subset is sufficient to generate the same data as the other tools
+
+Every tool was benchmark in cold and hot conditions. For `git` the first run in a repository was
+considered cold, with the following runs considered hot. `lg2` was patched to compute results twice
+in a single invocation without freeing the repository in between; the second run was considered hot.
+The same patching was not done for `git` because `git` cannot be easily modified to refresh inmemory
+index state between invocations; in fact, this limitation is one of the primary reasons developers
+use libgit2. `gitstatusd` was benchmarked similarly to `lg2` with two result computations in the
+same invocation.
+
+Two commands were benchmarked: `status` and `describe`.
+
+### Status
+
+In this benchmark all tools were computing the equivalent of `git status`. Lower numbers are better.
+
+| Tool          |      Cold  |         Hot |
+|---------------|-----------:|------------:|
+| **gitstatus** | **291 ms** | **30.9 ms** |
+| git           |     876 ms |      295 ms |
+| lg2           |    1730 ms |     1310 ms |
+
+gitstatusd is substantially faster than the alternatives, especially on hot runs. Note that hot runs
+are of primary importance to the main use case of gitstatus in interactive shells.
+
+The performance of `git status` fluctuated wildly in this benchmarks for reasons unknown to the
+author. Moreover, performance is sticky -- once `git status` settles around a number, it stays
+there for a long time. Numbers as diverse as 295, 352, 663 and 730 had been observed on hot runs on
+the same repository. The number in the table is the lowest (fastest or best) that `git status` had
+shown.
+
+### Describe
+
+In this benchmark all tools were computing the equivalent of `git describe --tags --exact-match`
+to find tags that resolve to the same commit as `HEAD`. Lower numbers are better.
+
+| Tool          |       Cold  |           Hot |
+|---------------|------------:|--------------:|
+| **gitstatus** | **4.04 ms** | **0.0345 ms** |
+| git           |     18.0 ms |       14.5 ms |
+| lg2           |      185 ms |       45.2 ms |
+
+gitstatusd is once again faster than the alternatives, more so on hot runs.
+
+## Why fast
+
+Since gitstatusd doesn't have to print all staged/unstaged/untracked files but only report
+whether there are any, it can terminate repository scan early. It can also remember which files
+were dirty on the previous run and check them first on the next run to avoid the scan entirely if
+the files are still dirty. However, the benchmarks above were performed in a clean repository where
+these shortcuts do not trigger. All benchmarked tools had to do the same work -- check the status
+of every file in the index to see if it has changed, check every directory for newly created files,
+etc. And yet, gitstatusd came ahead by a large margin. This section describes what it does that
+makes it so fast.
+
+Most of the following comparisons are done against libgit2 rather than git because of the author's
+familiarity with the former but not the with latter. libgit2 has clean, well-documented APIs and an
+elegant implementation, which makes it so much easier to work with and to analyze performance
+bottlenecks.
+
+### Summary for the impatient
+
+Under the benchmark conditions described above, the equivalent of libgit2's
+`git_diff_index_to_workdir` (the most expensive part of `status` command) is 46.3 times faster in
+gitstatusd. The speedup comes from the following sources.
+
+* gitstatusd uses more efficient data structures and algorithms and employs performance-conscious
+coding style throughout the codebase. This reduces CPU time in userspace by 32x compared to libgit2.
+* gitstatusd uses less expensive system calls and makes fewer of them. This reduces CPU time spent
+in kernel by 1.9x.
+* gitstatusd can utilize multiple cores to scan index and workdir in parallel with almost perfect
+scaling. This reduces total run time by 12.4x while having virtually no effect on total CPU time.
+
+### Problem statement
+
+The most resource-intensive part of the `status` command is finding the difference between _index_
+and _workdir_ (`git_diff_index_to_workdir` in libgit2). Index is a list of all files in the git
+repository with their last modification times. This is an obvious simplification but it suffices for
+this exposition. On disk, index is stored sorted by file path. Here's an example of git index:
+
+| File        | Last modification time |
+|-------------|-----------------------:|
+| Makefile    |   2019-04-01T14:12:32Z |
+| src/hello.c |   2019-04-01T14:12:00Z |
+| src/hello.h |   2019-04-01T14:12:32Z |
+
+This list needs to be compared to the list of files in the working directory. If any of the files
+listed in the index are missing from the workdir or have different last modification time, they are
+"unstaged" in gitstatusd parlance. If you run `git status`, they'll be shown as "changes not staged
+for commit". Thus, any implementation of `status` command has to call `stat()` or one of its
+variants on every file in the index.
+
+In addition, all files in the working directory for which there is no entry in the index at all are
+"untracked". `git status` will show them as "untracked files". Finding untracked files requires some
+form of work directory traversal.
+
+### Single-threaded scan
+
+Let's see how `git_diff_index_to_workdir` from libgit2 accomplishes these tasks. Here's its CPU
+profile from 200 hot runs over chromium repository.
+
+![libgit2 CPU profile (hot)](
+  https://raw.githubusercontent.com/romkatv/gitstatus/1ac366952366d89980b3f3484f270b4fa5ae4293/cpu-profile-libgit2.png)
+
+(The CPU profile was created with [gperftools](https://github.com/gperftools/gperftools) and
+rendered with [pprof](https://github.com/google/pprof)).
+
+We can see `__GI__lxstat` taking a lot of time. This is the `stat()` call for every file in the
+index. We can also identify `__opendir`, `__readdir` and `__GI___close_nocancel` -- glibc wrappers
+for reading the contents of a directory. This is for finding untracked files. Out of the total 232
+seconds, 111 seconds -- or 47.7% -- was spent on these calls. The rest is computation -- comparing
+strings, sorting arrays, etc.
+
+Now let's take a look at the CPU profile of gitstatusd on the same task.
+
+![gitstatusd CPU profile (hot)](
+  https://raw.githubusercontent.com/romkatv/gitstatus/1ac366952366d89980b3f3484f270b4fa5ae4293/cpu-profile-gitstatusd-hot.png)
+
+The first impression is that this profile looks pruned. This isn't an artifact. The profile was
+generated with the same tools and the same flags as the profile of libgit2.
+
+Since both profiles were generated from the same workload, absolute numbers can be compared. We can
+see that gitstatusd took 62 seconds in total compared to libgit2's 232 seconds. System calls at the
+core of the algorithm are cleary visible. `__GI___fxstatat` is a flavor of `stat()`, and the other
+three calls -- `__libc_openat64`, `__libc_close` and `__GI___fxstat` are responsible for opening
+directories and finding untracked files. Notice that there is almost nothing else in the profile
+apart from these calls. The rest of the code accounts for 3.77 seconds of CPU time -- 32 times less
+than in libgit2.
+
+So, one reason gitstatusd is fast is that it has efficient diffing code -- very little time is spent
+outside of kernel. However, if we look closely, we can notice that system calls in gitstatusd are
+_also_ faster than in libgit2. For example, libgit2 spent 72.07 seconds in `__GI__lxstat` while
+gitstatusd spent only 48.82 seconds in `__GI___fxstatat`. There are two reasons for this difference.
+First, libgit2 makes more `stat()` calls than is strictly required. It's not necessary to stat
+directories because index only has files. There are 25k directories in chromium repository (and 300k
+files) -- that's 25k `stat()` calls that could be avoided. The second reason is that libgit2 and
+gitstatusd use different flavors of `stat()`. libgit2 uses `lstat()`, which takes a path to the file
+as input. Its performance is linear in the number of subdirectories in the path because it needs to
+perform a lookup for every one of them and to check permissions. gitstatusd uses `fstatat()`, which
+takes a file descriptor to the parent directory and a name of the file. Just a single lookup, less
+CPU time.
+
+Similarly to `lstat()` vs `fstatat()`, it's faster to open files and directories with `openat()`
+from the parent directory file descriptor than with regular `open()` that accepts full file path.
+gitstatusd takes advantage of `openat()` to open directories as fast as possible. It opens about 90%
+of the directories (this depends on the actual directory structure of the repository) from the
+immediate parent -- the most efficient way -- and the remaining 10% it opens from the repository's
+root directory. The reason it's done this way is to keep the maximum number of simultaneously open
+file descriptors bounded. libgit2 can have O(repository depth) simultaneously open file descriptors,
+which may be OK for a single-threaded application but can balloon to a large number when scans are
+done by many threads simultaneously, like in gitstatusd.
+
+There is no equivalent to `__opendir` or `__readdir` in the gitstatusd profile because it uses the
+equivalent of [untracked cache](https://git-scm.com/docs/git-update-index#_untracked_cache) from
+git. On the first scan of the workdir gitstatusd lists all files just like libgit2. But, unlike
+libgit2, it remembers the last modification time of every directory along with the list of
+untracked files under it. On the next scan, gitstatusd can skip listing files in directories whose
+last modification time hasn't changed.
+
+To summarize, here's what gitstatusd was doing when the CPU profile was captured:
+
+1. `__libc_openat64`: Open every directory for which there are files in the index.
+2. `__GI___fxstat`: Check last modification time of the directory. Since it's the same as on the
+   last scan, this directory has the same list of untracked files as before, which is empty (the
+   repository is clean).
+3. `__GI___fxstatat`: Check last modification time for every file in the index that belongs to this
+   directory.
+4. `__libc_close`: Close the file descriptor to the directory.
+
+Here's how the very first scan of a repository looks like in gitstatusd:
+
+![gitstatusd CPU profile (cold)](
+  https://raw.githubusercontent.com/romkatv/gitstatus/1ac366952366d89980b3f3484f270b4fa5ae4293/cpu-profile-gitstatusd-cold.png)
+
+(Some glibc functions are mislabel on this profile. `explicit_bzero` and `__nss_passwd_lookup` are
+in reality `strcmp` and `memcmp`.)
+
+This is a superset of the previous -- hot -- profile, with an extra `syscall` and string sorting for
+directory listing. gitstatusd uses `getdents64` Linux system call directly, bypassing the glibc
+wrapper that libgit2 uses. This is 23% faster. The details of this optimization can be found in a
+[separate document](docs/listdir.md).
+
+### Multithreading
+
+The diffing algorithm in gitstatusd was designed from the ground up with the intention of using it
+concurrently from multiple threads. With a fast SSD, `status` is CPU bound, so taking advantage of
+all available CPU cores is an obvious way to yield results faster.
+
+gitstatusd exhibits almost perfect scaling from multithreading. Engaging all cores allows it to
+produce results 12.4 times faster than in single-threaded execution. This is on Intel i9-7900X with
+10 cores (20 with hyperthreading) with single-core frequency of 4.3GHz and all-core frequency of
+4.0GHz.
+
+Note: `git status` also uses all available cores in some parts of its algorithm while `lg2` does
+everything in a single thread.
+
+### Postprocessing
+
+Once the difference between the index and the workdir is found, we have a list of _candidates_ --
+files that may be unstaged or untracked. To make the final judgement, these files need to be checked
+against `.gitignore` rules and a few other things.
+
+gitstatusd uses [patched libgit2](https://github.com/romkatv/libgit2) for this step. This fork
+adds several optimizations that make libgit2 faster. The patched libgit2 performs more than twice
+as fast in the benchmark as the original even without changes in the user code (that is, in the
+code that uses the libgit2 APIs). The fork also adds several API extensions, most notable of which
+is the support for multi-threaded scans. If `lg2 status` is modified to take advantage of these
+extensions, it outperforms the original libgit2 by a factor of 18. Lastly, the fork fixes a score of
+bugs, most of which become apparent only when using libgit2 from multiple threads.
+
+_WARNING: Changes to libgit2 are extensive but the testing they underwent isn't. It is
+**not recommended** to use the patched libgit2 in production._
+
+## Requirements
+
+* To compile: binutils, cmake, gcc, g++, git and GNU make.
+* To run: Linux, macOS, FreeBSD, Android, WSL, Cygwin or MSYS2.
+
+## Compiling
+
+There are prebuilt `gitstatusd` binaries in [releases](
+  https://github.com/romkatv/gitstatus/releases). When using the official shell bindings
+provided by gitstatus, the right binary for your architecture gets downloaded automatically.
+
+If prebuilt binaries don't work for you, you'll need to get your hands dirty.
+
+### Compiling for personal use
+
+```zsh
+git clone --depth=1 https://github.com/romkatv/gitstatus.git
+cd gitstatus
+./build -w -s -d docker
+```
+
+Users in mainland China can use the official mirror on gitee.com for faster download.<br>
+中国大陆用户可以使用 gitee.com 上的官方镜像加速下载.
+
+```zsh
+git clone --depth=1 https://gitee.com/romkatv/gitstatus.git
+cd gitstatus
+./build -w -s -d docker
+```
+
+- If it says that `-d docker` is not supported on your OS, remove this flag.
+- If it says that `-s` is not supported on your OS, remove this flag.
+- If it tell you to install docker but you cannot or don't want to, remove `-d docker`.
+- If it says that some command is missing, install it.
+
+If everything goes well, the newly built binary will appear in `./usrbin`. It'll be picked up
+by shell bindings automatically.
+
+When you update shell bindings, they may refuse to work with the binary you've built earlier. In
+this case you'll need to rebuild.
+
+If you are using gitstatus through [Powerlevel10k](https://github.com/romkatv/powerlevel10k), the
+instructions are the same except that you don't need to clone gitstatus. Instead, change your
+current directory to `/path/to/powerlevel10k/gitstatus` (`/path/to/powerlevel10k` is the directory
+where you've installed Powerlevel10k) and run `./build -w -s -d docker` from there as described
+above.
+
+### Compiling for distribution
+
+It's currently neither easy nor recommended to package and distribute gitstatus. There are no
+instructions you can follow that would allow you to easily update your package when new versions of
+gitstatus are released. This may change in the future but not soon.

+Usage: build [-m ARCH] [-c CPU] [-d CMD] [-i IMAGE] [-s] [-w]
+
+Options:
+
+  -m ARCH   `uname -m` from the target machine; defaults to `uname -m`
+            from the local machine
+  -c CPU    generate machine instructions for CPU of this type; this
+            value gets passed as `-march` (or `-mcpu` for ppc64le) to gcc;
+            inferred from ARCH if not set explicitly
+  -d CMD    build in a Docker container and use CMD as the `docker`
+            command; e.g., `-d docker` or `-d podman`
+  -i IMAGE  build in this Docker image; inferred from ARCH if not set
+            explicitly
+  -s        install whatever software is necessary for build to
+            succeed; on some operating systems this option is not
+            supported; on others it can have partial effect
+  -w        automatically download tarballs for dependencies if they
+            do not already exist in ./deps; dependencies are described
+            in ./build.info

+# Fast directory listing
+
+In order to find untracked files in a git repository, [gitstatusd](../README.md) needs to list the
+contents of every directory. gitstatusd does it 27% faster than a reasonable implementation that a
+seasoned C/C++ practitioner might write. This document explains the optimizations that went into it.
+As directory listing is a common operation, many other projects can benefit from applying these
+optimizations.
+
+## v1
+
+Given a path to a directory, `ListDir()` must produce the list of files in that directory. Moreover,
+the list must be sorted lexicographically to enable fast comparison with Git index.
+
+The following C++ implementation gets the job done. For simplicity, it returns an empty list on
+error.
+
+```c++
+vector<string> ListDir(const char* dirname) {
+  vector<string> entries;
+  if (DIR* dir = opendir(dirname)) {
+    while (struct dirent* ent = (errno = 0, readdir(dir))) {
+      if (!Dots(ent->d_name)) entries.push_back(ent->d_name);
+    }
+    if (errno) entries.clear();
+    sort(entries.begin(), entries.end());
+    closedir(dir);
+  }
+  return entries;
+}
+```
+
+Every directory has entries `"."` and `".."`, which we aren't interested in. We filter them out with
+a helper function `Dots()`.
+
+```c++
+bool Dots(const char* s) { return s[0] == '.' && (!s[1] || (s[1] == '.' && !s[2])); }
+```
+
+To check how fast `ListDir()` performs, we can run it many times on a typical directory. One million
+runs on a directory with 32 files with 16-character names takes 12.7 seconds.
+
+## v2
+
+Experienced C++ practitioners will scoff at our implementation of `ListDir()`. If it's meant to be
+efficient, returning `vector<string>` is an unaffordable convenience. To avoid heap allocations we
+can use a simple arena that will allow us to reuse memory between different `ListDir()` calls.
+
+(Changed and added lines are marked with comments.)
+
+```c++
+void ListDir(const char* dirname, string& arena, vector<char*>& entries) {  // +
+  entries.clear();                                                          // +
+  if (DIR* dir = opendir(dirname)) {
+    arena.clear();                                                          // +
+    while (struct dirent* ent = (errno = 0, readdir(dir))) {
+      if (!Dots(ent->d_name)) {
+        entries.push_back(reinterpret_cast<char*>(arena.size()));           // +
+        arena.append(ent->d_name, strlen(ent->d_name) + 1);                 // +
+      }
+    }
+    if (errno) entries.clear();
+    for (char*& p : entries) p = &arena[reinterpret_cast<size_t>(p)];      // +
+    sort(entries.begin(), entries.end(),                                   // +
+         [](const char* a, const char* b) { return strcmp(a, b) < 0; });   // +
+    closedir(dir);
+  }
+}
+```
+
+To make performance comparison easier, we can normalize them relative to the baseline. v1 will get
+performance score of 100. A twice-as-fast alternative will be 200.
+
+| version |     optimization           |     score |
+|---------|----------------------------|----------:|
+| v1      | baseline                   |     100.0 |
+| **v2**  | **avoid heap allocations** | **112.7** |
+
+Avoiding heap allocations makes `ListDir()` 12.7% faster. Not bad. As an added bonus, those casts
+will fend off the occasional frontend developer who accidentally wanders into the codebase.
+
+## v3
+
+`opendir()` is an expensive call whose performance is linear in the number of subdirectories in the
+path because it needs to perform a lookup for every one of them. We can replace it with `openat()`,
+which takes a file descriptor to the parent directory and a name of the subdirectory. Just a single
+lookup, less CPU time. This optimization assumes that callers already have a descriptor to the
+parent directory, which is indeed the case for gitstatusd, and is often the case in other
+applications that traverse filesystem.
+
+```c++
+void ListDir(int parent_fd, const char* dirname, string& arena, vector<char*>& entries) {   // +
+  entries.clear();
+  int dir_fd = openat(parent_fd, dirname, O_NOATIME | O_RDONLY | O_DIRECTORY | O_CLOEXEC);  // +
+  if (dir_fd < 0) return;                                                                   // +
+  if (DIR* dir = fdopendir(dir_fd)) {
+    arena.clear();
+    while (struct dirent* ent = (errno = 0, readdir(dir))) {
+      if (!Dots(ent->d_name)) {
+        entries.push_back(reinterpret_cast<char*>(arena.size()));
+        arena.append(ent->d_name, strlen(ent->d_name) + 1);
+      }
+    }
+    if (errno) entries.clear();
+    for (char*& p : entries) p = &arena[reinterpret_cast<size_t>(p)];
+    sort(entries.begin(), entries.end(),
+         [](const char* a, const char* b) { return strcmp(a, b) < 0; });
+    closedir(dir);
+  } else {                                                                                  // +
+    close(dir_fd);                                                                          // +
+  }                                                                                         // +
+}
+```
+
+This is worth about 3.5% in speed.

+
+## v4
+
+Copying file names to the arena isn't free but it doesn't seem like we can avoid it. Poking around
+we can see that the POSIX API we are using is implemented on Linux on top of `getdents64` system
+call. Its documentation isn't very encouraging:
+
+```text
+These are not the interfaces you are interested in.  Look at
+readdir(3) for the POSIX-conforming C library interface.  This page
+documents the bare kernel system call interfaces.
+
+Note: There are no glibc wrappers for these system calls.
+```
+
+Hmm... The API looks like something we can take advantage of, so let's try it anyway.
+
+First, we'll need a simple `Arena` class that can allocate 8KB blocks of memory.
+
+```c++
+class Arena {
+ public:
+  enum { kBlockSize = 8 << 10 };
+
+  char* Alloc() {
+    if (cur_ == blocks_.size()) blocks_.emplace_back(kBlockSize, 0);
+    return blocks_[cur_++].data();
+  }
+
+  void Clear() { cur_ = 0; }
+
+ private:
+  size_t cur_ = 0;
+  vector<string> blocks_;
+};
+```
+
+Next, we need to define `struct dirent64_t` ourselves because there is no wrapper for the system
+call we are about to use.
+
+```c++
+struct dirent64_t {
+  ino64_t d_ino;
+  off64_t d_off;
+  unsigned short d_reclen;
+  unsigned char d_type;
+  char d_name[];
+};
+```
+
+Finally we can get to the implementation of `ListDir()`.
+
+```c++
+void ListDir(int parent_fd, Arena& arena, vector<char*>& entries) {                       // +
+  entries.clear();
+  int dir_fd = openat(parent_fd, dirname, O_NOATIME | O_RDONLY | O_DIRECTORY | O_CLOEXEC);
+  if (dir_fd < 0) return;
+  arena.Clear();                                                                          // +
+  while (true) {                                                                          // +
+    char* buf = arena.Alloc();                                                            // +
+    int n = syscall(SYS_getdents64, dir_fd, buf, Arena::kBlockSize);                      // +
+    if (n <= 0) {                                                                         // +
+      if (n) entries.clear();                                                             // +
+      break;                                                                              // +
+    }                                                                                     // +
+    for (int pos = 0; pos < n;) {                                                         // +
+      auto* ent = reinterpret_cast<dirent64_t*>(buf + pos);                               // +
+      if (!Dots(ent->d_name)) entries.push_back(ent->d_name);                             // +
+      pos += ent->d_reclen;                                                               // +
+    }                                                                                     // +
+  }                                                                                       // +
+  sort(entries.begin(), entries.end(),
+       [](const char* a, const char* b) { return strcmp(a, b) < 0; });
+  close(dir_fd);
+}
+```
+
+How are we doing with this one?
+
+| version | optimization                     |     score |

+| v1      | baseline                         |     100.0 |

+| v3      | open directories with `openat()` |     116.2 |
+| **v4**  | **call `getdents64()` directly** | **137.8** |
+
+Solid 20% speedup. Worth the trouble. Unfortunately, we now have just one `reinterpret_cast` instead
+of two, and it's not nearly as scary-looking. Hopefully with the next iteration we can get back some
+of that evil vibe of low-level code.
+
+As a bonus, every element in `entries` has `d_type` at offset -1. This can be useful to the callers
+that need to distinguish between regular files and directories (gitstatusd, in fact, needs this).
+Note how `ListDir()` implements this feature at zero cost, as a lucky accident of `dirent64_t`
+memory layout.
+
+## v5
+
+The CPU profile of `ListDir()` reveals that almost all userspace CPU time is spent in `strcmp()`.
+Digging into the source code of `std::sort()` we can see that it uses Insertion Sort for short
+collections. Our 32-element vector falls under the threshold. Insertion Sort makes `O(N^2)`
+comparisons, hence a lot of CPU time in `strcmp()`. Switching to `qsort()` or
+[Timsort](https://en.wikipedia.org/wiki/Timsort) is of no use as all good sorting algorithms fall
+back to Insertion Sort.
+
+If we cannot make fewer comparisons, perhaps we can make each of them faster? `strcmp()` compares
+characters one at a time. It cannot read ahead as it can be illegal to touch memory past the first
+null byte. But _we_ know that it's safe to read a few extra bytes past the end of `d_name` for every
+entry except the last in the buffer. And since we own the buffer, we can overallocate it so that
+reading past the end of the last entry is also safe.
+
+Combining these ideas with the fact that file names on Linux are at most 255 bytes long, we can
+invoke `getdents64()` like this:
+
+```c++
+int n = syscall(SYS_getdents64, dir_fd, buf, Arena::kBlockSize - 256);
+```
+
+And then compare entries like this:
+
+```c++
+[](const char* a, const char* b) { return memcmp(a, b, 255) < 0; }

+
+This version doesn't give any speedup compared to the previous but it opens an avenue for another
+optimization. The pointers we pass to `memcmp()` aren't aligned. To be more specific, their
+numerical values are `N * 8 + 3` for some `N`. When given such a pointer, `memcmp()` will check the
+first 5 bytes one by one, and only then switch to comparing 8 bytes at a time. If we can handle the
+first 5 bytes ourselves, we can pass aligned memory to `memcmp()` and take full advantage of its
+vectorized loop.
+
+Here's the implementation:
+
+```c++
+uint64_t Read64(const void* p) {                                                          // +
+  uint64_t x;                                                                             // +
+  memcpy(&x, p, sizeof(x));                                                               // +
+  return x;                                                                               // +
+}                                                                                         // +
+
+void ByteSwap64(void* p) {                                                                // +
+  uint64_t x = __builtin_bswap64(Read64(p));                                              // +
+  memcpy(p, &x, sizeof(x));                                                               // +
+}                                                                                         // +
+
+void ListDir(int parent_fd, Arena& arena, vector<char*>& entries) {
+  entries.clear();
+  int dir_fd = openat(parent_fd, dirname, O_NOATIME | O_RDONLY | O_DIRECTORY | O_CLOEXEC);
+  if (dir_fd < 0) return;
+  arena.Clear();
+  while (true) {
+    char* buf = arena.Alloc();
+    int n = syscall(SYS_getdents64, dir_fd, buf, Arena::kBlockSize - 256);                // +
+    if (n <= 0) {
+      if (n) entries.clear();
+      break;
+    }
+    for (int pos = 0; pos < n;) {
+      auto* ent = reinterpret_cast<dirent64_t*>(buf + pos);
+      if (!Dots(ent->d_name)) {
+        ByteSwap64(ent->d_name);                                                          // +
+        entries.push_back(ent->d_name);
+      }
+      pos += ent->d_reclen;
+    }
+  }
+  sort(entries.begin(), entries.end(), [](const char* a, const char* b) {
+    uint64_t x = Read64(a);                                                               // +
+    uint64_t y = Read64(b);                                                               // +
+    return x < y || (x == y && a != b && memcmp(a + 5, b + 5, 256) < 0);                  // +
+  });
+  for (char* p : entries) ByteSwap64(p);                                                  // +
+  close(dir_fd);
+}
+```
+
+This is for Little Endian architecture. Big Endian doesn't need `ByteSwap64()`, so it'll be a bit
+faster.

+## Conclusion
+
+Through a series of incremental improvements we've sped up directory listing by 43.3% compared to a
+naive implementation (v1) and 27.2% compared to a reasonable implementation that a seasoned C/C++
+practitioner might write (v2).
+
+However, these numbers are based on an artificial benchmark while the real judge is always the real
+code. Our goal was to speed up gitstatusd. Benchmark was just a tool. Thankfully, the different
+versions of `ListDir()` have the same comparative performance within gitstatusd as in the benchmark.
+In truth, the directory chosen for the benchmark wasn't arbitrary. It was picked by sampling
+gitstatusd when it runs on [chromium](https://github.com/chromium/chromium) git repository.
+
+The final version of `ListDir()` spends 97% of its CPU time in the kernel. If we assume that it
+makes the minimum possible number of system calls and these calls are optimal (true to the best
+of my knowledge), it puts the upper bound on possible future performance improvements at just 3%.
+There is almost nothing left in `ListDir()` to optimize.

+
+If positional arguments are specified, call this on success:
+
+  CMD [ARG]... DAEMON VERSION INSTALLED
+
+DAEMON is path to gitstatusd. VERSION is a glob pattern for the
+version this daemon should support; it's supposed to be passed as
+-G to gitstatusd. INSTALLED is 1 if gitstatusd has just been
+downloaded and 0 otherwise.
+
+Options:
+
+  -s KERNEL  use this instead of lowercase `uname -s`
+  -m ARCH    use this instead of lowercase `uname -m`
+  -d DIR     use this instead of `dirname "$0"`
+  -p CMD     eval this every second while downloading gitstatusd
+  -e ERRFD   write error messages to this file descriptor
+  -f         download gitstatusd even if there is one locally
+  -n         do not download gitstatusd (fail instead)

+# This script does not have a stable API.
+#
+# Usage: mbuild [-b git-ref] [kernel-arch]...
+#
+# Builds a bunch of gitstatusd-* binaries. Without arguments builds binaries
+# for all platforms. git-ref defaults to master.
+#
+# Before using this script you need to set up build servers and list them
+# in ~/.ssh/config. There should be a Host entry for every value of `assets`
+# association defined below. VMs and cloud instances work as well as physical
+# machines, including localhost. As long as the machine has been set up as
+# described below and you can SSH to it without password, it should work.
+#
+#                    ===[ Build Server Setup ]===
+#
+#                              Linux
+#
+# - Install docker.
+#   $ apt install docker.io     # adjust appropriately if there is no `apt`
+#   $ usermod -aG docker $USER  # not needed if going to build as root
+# - Install git.
+#   $ apt install git           # adjust appropriately if there is no `apt`
+#
+#                              macOS
+#
+# - Install compiler tools:
+#   $ xcode-select --install
+# - Install homebrew: https://brew.sh/.
+#   $ bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
+#
+#                             FreeBSD
+#
+# - Install git.
+#   $ pkg install git
+#
+#                             Windows
+#
+# - Disable Windows Defender (optional).
+#   ps> Set-MpPreference -DisableRealtimeMonitoring $true
+# - Install 64-bit and 32-bit msys2: https://www.msys2.org/wiki/MSYS2-installation/.
+#   - Open each of them after installation, type `pacman -Syu --noconfirm` and close the window.
+#   - Then run in powershell while having no msys2 or cygwin windows open:
+#     ps> C:\msys32\autorebase.bat
+#     ps> C:\msys64\autorebase.bat
+# - Install 64-bit and 32-bit cygwin: https://cygwin.com/install.html.
+#   - Choose to install 32-bit to c:/cygwin32 instead of the default c:/cygwin.
+#   - Select these packages: binutils, cmake, gcc-core, gcc-g++, git, make, perl, wget.
+#
+# IMPORTANT: Install msys2 and cygwin one at a time.
+#
+# IMPORTANT: msys2 builder can reboot the build machine.
+#
+# Option 1: OpenSSH for Windows
+#
+# - Install OpenSSH: https://docs.microsoft.com/en-us/windows-server/administration/openssh/openssh_install_firstuse.
+#   ps> Add-WindowsCapability -Online -Name OpenSSH.Server~~~~0.0.1.0
+#   ps> Start-Service sshd
+#   ps> Set-Service -Name sshd -StartupType 'Automatic'
+# - Enable publickey authentication: https://stackoverflow.com/a/50502015/1095235.
+#   ps> cd $env:USERPROFILE
+#   ps> mkdir .ssh
+#   ps> notepad.exe .ssh/authorized_keys
+#     - Paste your public key, save, close.
+#   ps> icacls .ssh/authorized_keys /inheritance:r
+#   ps> notepad.exe C:\ProgramData\ssh\sshd_config
+#     - Comment out these two lines, save, close:
+#       # Match Group administrators
+#       #   AuthorizedKeysFile __PROGRAMDATA__/ssh/administrators_authorized_keys
+#   ps> Restart-Service sshd
+#
+# Option 2: OpenSSH from WSL
+#
+# - Install WSL.
+# - Install Ubuntu.
+# - Install sshd.
+#   $ apt install openssh-server
+#   $ dpkg-reconfigure openssh-server
+#   $ cat >/etc/ssh/sshd_config <<\END
+#     ClientAliveInterval 60

+#     AllowStreamLocalForwarding no
+#     AuthenticationMethods publickey
+#   END
+#   service ssh --full-restart
+# - Add your public ssh key to ~/.ssh/authorized_keys.

+when directory cannot be shortened any further, start chopping off segments from the left and
+replacing the chopped off part with `…`. e.g., `…/x/anchor/y/anchor`. the shortest dir
+representation is thus `…/last` or `…/last` depending on whether the last segment is an anchor.

+- add swiftenv
+
+---
+
+- add faq: how to customize directory shortening? mention POWERLEVEL9K_DIR_TRUNCATE_BEFORE_MARKER,
+POWERLEVEL9K_DIR_MAX_LENGTH and co., and truncate_to_last.
+
+---
+
+fix a bug in zsh: https://github.com/romkatv/powerlevel10k/issues/502. to reproduce:
+
+```zsh
+emulate zsh -o prompt_percent -c 'print -P "%F{#ff0000}red%F{green}%B bold green"'
+```
+
+---
+
+add `p10k explain` that prints something like this:
+
+```text
+segment     icons meaning
+
+---
+
+---
+
+---
+
+---
+
+---
+
+---
+
+---
+
+---
+--
+status      ✔  ✘  exit code of the last command
+```
+
+implement it the hard way: for every enabled segment go over all its {state,icon} pairs, resolve
+the icon (if not absolute), apply VISUAL_IDENTIFIER_EXPANSION, remove leading and trailing
+whitespace and print without formatting (sort of like `print -P | cat`); print segment names in
+green and icons in bold; battery can have an unlimited number of icons, so `...` would be needed
+(based on total length of concatenated icons rather than the number of icons); user-defined
+segments would have "unknown" icons by default (yellow and not bold); can allow them to
+participate by defining `explainprompt_foo` that populates array `reply` with strings like this:
+'-s STATE -i LOCK_ICON +r'; the first element must be segment description.
+
+---
+
+add `docker_context` prompt segment; similar to `kubecontext`; the data should come from
+`currentContext` field in `~/.docker/config.json` (according to
+https://github.com/starship/starship/issues/995); there is also `DOCKER_CONTEXT`; more info:
+https://docs.docker.com/engine/reference/commandline/context_use; also
+https://github.com/starship/starship/pull/996.
+
+---
+
+support `env`, `ionice` and `strace` precommands in `parser.zsh`.
+
+---
+
+Add ruler to configuration wizard. Options: `─`, `·`, `╌`, `┄`, `▁`, `═`.
+
+---
+
+Add frame styles to the wizard.
+
+```text
+╭─
+╰─
+
+┌─
+└─
+
+┏━
+┗━
+
+╔═
+╚═
+
+▛▀
+▙▄
+```
+
+Prompt connection should have matching options.
+
+---
+
+Add `POWERLEVEL9K_{LEFT,RIGHT}_SEGMENT_MIRROR_SEPARATOR`. If set, left segments get separated with
+`POWERLEVEL9K_LEFT_SEGMENT_SEPARATOR` followed by `POWERLEVEL9K_LEFT_SEGMENT_MIRROR_SEPARATOR`.
+Each is drawn without background. The first with the foreground of left segment, the second with
+the background of right segment. To insert space in between, embed it in
+`POWERLEVEL9K_{LEFT,RIGHT}_SEGMENT_MIRROR_SEPARATOR`.
+`POWERLEVEL9K_{LEFT,RIGHT}_SUBSEGMENT_SEPARATOR` is unused.
+
+---
+
+Add *Segment Connection* screen to configuration wizard with options *Fused*, *Touching* and
+*Disjoint*. The last two differ by the absence/presence of space between `SEGMENT_SEPARATOR` and
+`SEGMENT_MIRROR_SEPARATOR`.
+
+*Fused* requires line separator (there is already a screen for it) but the other two options require
+two filled separators similar to heads and tail. Figure out how to present this choice.
+
+---
+
+Optimize auto-wizard check.
+
+```text
+time ( repeat 1000 [[ -z "${parameters[(I)POWERLEVEL9K_*~(POWERLEVEL9K_MODE|POWERLEVEL9K_CONFIG_FILE)]}" ]] )
+user=0.21s system=0.05s cpu=99% total=0.264
+
+time ( repeat 1000 [[ -z "${parameters[(I)POWERLEVEL9K_*]}" ]] )
+user=0.17s system=0.00s cpu=99% total=0.175
+```
+
+---
+
+Add the equivalent of `P9K_PYTHON_VERSION` to all `*env` segments where it makes sense.
+
+---
+
+Define `P9K_ICON` on initialization. Fill it with `$icon`. Duplicate every key that ends in `_ICON`.
+Respect `POWERLEVEL9K_VCS_STASH_ICON` overrides but not anything with segment name or state.
+
+Define `POWERLEVEL9K_VCS_*` parameters in config templates for all symbols used in
+`my_git_formatter`. Add missing entries to `icons`. Use `$P9K_ICON[...]` within `my_git_formatter`.
+Add a screen to the wizard to choose between clear and circled icons.
+
+---
+
+Add a screen to the wizard asking whether to set `POWERLEVEL9K_VCS_DISABLED_WORKDIR_PATTERN='~'`.
+Show it only if there is `$HOME/.git`. By default this parameter should be commented out.

+
+Thanks for opening an issue! For a project that deals with as many different things as P9k, debugging problems can be difficult. Please follow the guide, below, to create a bug report that will help us help you!
+
+### Before Opening a Bug
+P9k is lovingly maintained by volunteers, and we are happy to help you! You can help us by first making sure your issue hasn't already been solved before opening a new one. Please check the [Troubleshooting Guide](https://github.com/bhilburn/powerlevel9k/wiki/Troubleshooting) first. Many issues are actually local configuration problems, which may have previously been solved by another user - be sure to also [search the existing issues](https://github.com/bhilburn/powerlevel9k/issues?utf8=%E2%9C%93&q=is%3Aissue) before opening a new one.
+
+Once you've done these things, you can delete this section and proceed `=)`
+
+-----
+
+#### Describe Your Issue
+What is happening?
+
+Most issues are best explained with a screenshot. Please share one if you can!
+
+#### Have you tried to debug or fix it?
+
+Have you tinkered with your settings, and what happened when you did? Did you find a bit of code that you think might be the culprit? Let us know what you've done so far!
+
+#### Environment Information
+
+This information will help us understand your configuration.
+
+  - What version of ZSH are you using? You can use `zsh --version` to see this.
+  - Do you use a ZSH framework (e.g., Oh-My-ZSH, Antigen)?
+  - How did you install P9k (cloning the repo, by tarball, a package from your OS, etc.,)?
+  - What version of P9k are you using?
+  - Which terminal emulator do you use?
+
+#### Issues with Fonts & Icons
+You may delete this section if your issue is not font / icon related.
+
+  - Which font do you use?
+  - Which [font configuration mode](https://github.com/bhilburn/powerlevel9k/wiki/About-Fonts) are you using? You can check this with (`echo $POWERLEVEL9K_MODE`).
+  - Please share the contents of `$P9k/debug/font-issues.zsh`.
+  - If this is an icon problem, does the output of `$ get_icon_names` look correct?

+about: For performance Issues
+title: "[Performance]"
+labels: performance
+assignees: ''
+
+---
+
+Sorry to hear that the performance of P9K is not adequate. To fix this, please provide us with some hints.
+
+### Your Hardware
+
+Disk I/O is critical for P9K, so do you use a spinning disk, or a SSD?
+
+### Virtualization
+
+Do you use P9K in some sort of virtualization? This is also the case, if you use WSL on Windows..
+
+### How Fast is Fast
+
+Could you quantify how fast the specific segment is, that you think is slow?
+For example, if you think the `vcs` segment is slow, could you execute this command in the directory, where the segment is slow:
+
+```zsh
+time (repeat 10; do; prompt_vcs left 1 false >/dev/null; done;)
+```
+
+Also, please provide us with some context around the segment. In the `vcs` example:
+
+- How big is the repo?
+- Does it contain a lot of untracked files?
+- Does it contain a lot of git submodules?
+- Does it contain a lot of files in general?
+
+Additionally, you could install [zsh-prompt-benchmark](https://github.com/romkatv/zsh-prompt-benchmark), to benchmark the general performance of ZSH and P9K.
+
+If you don't know which segment is slow, could you remove one by one, and spot the one that made the greatest impact?

+
+There is now an option to use [nerd-fonts](https://github.com/ryanoasis/nerd-fonts) with P9k. Simply configure the `nerdfont-fontconfig`, and you'll be set!
+
+### `vcs` changes
+
+The VCS segment can now display icons for remote repo hosting services, including Github, Gitlab, and 'other'.
+
+### `dir` changes
+
+Added an option to configure the path separator. If you want something
+else than an ordinary slash, you could set
+`POWERLEVEL9K_DIR_PATH_SEPARATOR` to whatever you want.
+
+#### `truncate_with_package_name` now searches for `composer.json` as well
+
+Now `composer.json` files are searched as well. By default `package.json` still takes
+precedence. If you want to change that, set `POWERLEVEL9K_DIR_PACKAGE_FILES=(composer.json package.json)`.
+
+### New segment `command_execution_time` added
+
+Shows the duration a command needed to run. By default only durations over 3 seconds
+are shown (can be adjusted by setting POWERLEVEL9K_COMMAND_EXECUTION_TIME_THRESHOLD).
+

+This segment displays a lock icon if your user has no write permissions in the current folder.
+
+### New segment `disk_usage` added

+
+## v0.5.0
+
+### `load` and `ram` changes
+
+These two segments now support BSD.
+
+### `vcs` changes
+
+- We implemented a huge speed improvement for this segment.
+- Now this segment supports Subversion repositories.
+- Add ability to hide tags by setting `POWERLEVEL9K_VCS_HIDE_TAGS` to true.
+
+## `anaconda` changes
+
+Speed improvements for `anaconda` segment.
+
+## v0.4.0
+
+### Development changes
+
+From now on, development makes use of a CI system "travis".
+
+### `vcs` changes
+
+The default state was renamed to `clean`. If you overrode foreground
+or background color in the past, you need to rename your variables to:
+
+```zsh
+POWERLEVEL9K_VCS_CLEAN_FOREGROUND='cyan'
+POWERLEVEL9K_VCS_CLEAN_BACKGROUND='white'
+```
+
+Additionaly the vcs segment now has an `untracked` state which
+indicates that you have untracked files in your repository.
+
+The foreground color of actionformat is now configurable via:
+```zsh
+POWERLEVEL9K_VCS_ACTIONFORMAT_FOREGROUND='green'
+```
+
+Also, the vcs segment uses the foreground color it was configured to.
+That said, the variables `POWERLEVEL9K_VCS_FOREGROUND` and
+`POWERLEVEL9K_VCS_DARK_FOREGROUND` are no longer used. Instead use
+the proper variable `POWERLEVEL9K_VCS_<STATE>_FOREGROUND` to change
+foreground color.
+
+### `dir` Shortening Strategies
+
+There is now a path shortening strategy that will use the `package.json` file to
+shorten your directory path. See the documentation for the `dir` segment for more
+details.
+
+Also, the shorten delimiter was changed to an unicode ellipsis. It is configurable
+via `POWERLEVEL9K_SHORTEN_DELIMITER`.
+
+### `rbenv` changes
+
+The `rbenv` segment now makes use of the full rbenv command, so the correct
+ruby version is now shown if it differs from the globally one.
+
+### `node`, `nvm` Segments
+
+Improvements to speed / reliability.
+
+### `ram` changes
+
+The `ram` segment was split up into `ram` and `swap`. The
+`POWERLEVEL9K_RAM_ELEMENTS` variable is obsolete.
+
+### New segment `swap` added
+
+Due to the split up of the ram segment, this one was created. It
+shows the currently used swap size.
+
+### New segment `nodeenv` added
+
+Added new `nodeenv` segment that shows the currently used node environment.
+
+### New segment `aws_eb_env` added
+
+This segment displays the current Elastic Beanstalk environment.
+
+### New segment `chruby` added
+
+Added new `chruby` segment to support this version manager.
+
+### New segment `docker_machine` added
+
+Added new `docker_machine` segment that will show your Docker machine.
+
+### New segment `anaconda` added
+
+A new segment `anaconda` was added that shows the current used
+anaconda environment.
+
+## New segment `pyenv` added
+
+This segment shows your active python version as reported by `pyenv`.
+
+
+## v0.3.2
+
+### `vcs` changes
+
+A new state `UNTRACKED` was added to the `vcs` segment. So we now
+have 3 states for repositories: `UNTRACKED`, `MODIFIED`, and the
+default state. The `UNTRACKED` state is active when there are files
+in the repository directory which have not been added to the repo
+(the same as when the `+` icon appears). The default color for the
+`UNTRACKED` state is now yellow, and the default color for the
+`MODIFIED` state is now read, but those colors can be changed by
+setting these variables, for example:
+
+```zsh
+POWERLEVEL9K_VCS_MODIFIED_FOREGROUND='black'
+POWERLEVEL9K_VCS_MODIFIED_BACKGROUND='white'
+POWERLEVEL9K_VCS_UNTRACKED_FOREGROUND='green'
+POWERLEVEL9K_VCS_UNTRACKED_BACKGROUND='blue'
+```
+
+## v0.3.1
+
+### `dir` changes
+
+A new state `HOME_SUBFOLDER` was added. So if you want to overwrite
+colors for this segment, also set this variables:
+```zsh
+POWERLEVEL9K_DIR_HOME_SUBFOLDER_BACKGROUND='black'
+POWERLEVEL9K_DIR_HOME_SUBFOLDER_FOREGROUND='white'
+```
+
+### `background_jobs` changes
+Now displays the number of background jobs if there's more than 1.
+You can disable it by setting :
+```zsh
+POWERLEVEL9K_BACKGROUND_JOBS_VERBOSE=false
+```
+
+## v0.3.0
+
+### Introduced "visual identifiers" to the segments
+
+Now almost every segment can have a visual identifier, which is an
+icon whose color could be adjusted by users.
+
+### Added ability for "joined" segments
+
+You can now merge segments together by suffixing the segment name with "_joined".
+For Developers: Be aware that the order of parameters in left/right_prompt_segment
+has changed. Now a boolean parameter must be set as second parameter (true if joined).
+
+### `dir` changes
+
+This segment now has "state", which means you now can change the colors seperatly
+depending if you are in your homefolder or not.
+Your variables for that should now look like:
+```zsh
+POWERLEVEL9K_DIR_HOME_BACKGROUND='green'
+POWERLEVEL9K_DIR_HOME_FOREGROUND='cyan'
+POWERLEVEL9K_DIR_DEFAULT_BACKGROUND='red'
+POWERLEVEL9K_DIR_DEFAULT_FOREGROUND='yellow'
+```
+
+### `status` changes
+
+The `status` segment was split up into three segments. `background_jobs` prints
+an icon if there are background jobs. `root_indicator` prints an icon if the user
+is root. The `status` segment focuses now on the status only.
+The `status` segment also now has "state". If you want to overwrite the colors,
+you have to add the state to your variables:
+```zsh
+POWERLEVEL9K_STATUS_ERROR_BACKGROUND='green'
+POWERLEVEL9K_STATUS_ERROR_FOREGROUND='cyan'
+POWERLEVEL9K_STATUS_OK_BACKGROUND='red'
+POWERLEVEL9K_STATUS_OK_FOREGROUND='yellow'
+```
+
+### New segment `custom_command` added
+
+A new segment that allows users to define a custom command was added.
+
+### `virtualenv` changes
+
+This segment now respects `VIRTUAL_ENV_DISABLE_PROMPT`. If this variable is set
+to `true`, the segments does not get rendered.
+
+### `load` changes
+
+The `load` segement was split and a new segment `ram` was extracted. This new
+segment is able to show the free ram and used swap.
+
+### `vcs` changes
+
+This prompt uses the `VCS_INFO` subsystem by ZSH. From now on this subsystem
+is only invoked if a `vcs` segment was configured.
+
+### `rvm` changes
+
+This segment now does not invoke RVM directly anymore. Instead, is relys on the
+circumstance that RVM was invoked beforehand and just reads the environment
+variables '$GEM_HOME' and '$MY_RUBY_HOME'. It also now displays the used gemset.
+
+### New segment `battery` added
+
+A new segment that shows the battery status of your laptop was added.
+
+### New segment `go_version` added
+
+This segment shows the GO version.
+
+### New segment `nvm` added
+
+This segment shows your NodeJS version by using NVM (and if it is not 'default').
+
+### New segment `todo` added
+
+This segment shows your ToDos from [todo.sh](http://todotxt.com/).
+
+### New segment `rust_version` added
+
+This segment shows your local rust version.
+
+## v0.2.0
+
+### `longstatus` is now `status`
+
+The segments got merged together. To show the segment only if an error occurred,
+set `POWERLEVEL9K_STATUS_VERBOSE=false` (this is the same behavior as the old
+`status` segment.
+
+### Icon overriding mechanism added
+
+All icons can now be overridden by setting a variable named by the internal icon
+name. You can get a full list of icon name by calling `get_icon_names`.
+
+### Same color segements get visual separator
+
+This separator can be controlled by setting `POWERLEVEL9K_LEFT_SUBSEGMENT_SEPARATOR`
+or `POWERLEVEL9K_RIGHT_SUBSEGMENT_SEPARATOR`. By default this separator is
+printed in the foreground color.
+
+### `dir` segment has different strategies for truncation
+
+Now you can choose between `truncate_middle` or `truncate_from_right` by setting
+`POWERLEVEL9K_SHORTEN_STRATEGY`. Default behavior is unchanged (truncate whole
+directories). `POWERLEVEL9K_SHORTEN_DIR_LENGTH` can be used to influence how
+much will be truncated (either direcories or chars).
+
+### New segment `ip` added
+
+This segment shows your internal IP address. You can define which interfaces IP
+will be shown by specifying it via `POWERLEVEL9K_IP_INTERFACE`.
+
+### New segment `load` added
+
+This segment shows your computers 5min load average.
+
+### New segment `os_icon` added
+
+This segment shows a little indicator which OS you are running.
+
+### New segment `php_version` added
+
+This segment shows your PHP version.
+
+### New segment `vi_mode` added
+
+This segment gives you a hint in which VI-mode you currently are. This
+segment requires a proper configured VI-mode.
+
+### Added the ability to have empty left or right prompts
+
+By setting the according variable to an empty array, the left or right
+prompt will be empty.
+

+
+Powerlevel9k is a theme for ZSH which uses [Powerline
+Fonts](https://github.com/powerline/fonts). It can be used with vanilla ZSH or
+ZSH frameworks such as [Oh-My-Zsh](https://github.com/robbyrussell/oh-my-zsh),
+[Prezto](https://github.com/sorin-ionescu/prezto),
+[Antigen](https://github.com/zsh-users/antigen), and [many
+others](https://github.com/bhilburn/powerlevel9k/wiki/Install-Instructions).
+
+Get more out of your terminal. Be a badass. Impress everyone in 'Screenshot Your
+Desktop' threads. Use powerlevel9k.

+
+You can check out some other users' configurations in our wiki: [Show Off Your
+Config](https://github.com/bhilburn/powerlevel9k/wiki/Show-Off-Your-Config).
+
+There are a number of Powerline ZSH themes available, now. The developers of
+this theme focus on four primary goals:
+
+1. Give users a great out-of-the-box configuration with no additional
+   configuration required.
+2. Make customization easy for users who do want to tweak their prompt.
+3. Provide useful segments that you can enable to make your prompt even more
+   effective and helpful. We have prompt segments for everything from unit test
+   coverage to your AWS instance.
+4. Optimize the code for execution speed as much as possible. A snappy terminal
+   is a happy terminal.
+
+Powerlevel9k can be used to create both very useful and beautiful terminal environments:

+### Installation
+There are two installation steps to go from a vanilla terminal to a PL9k
+terminal. Once you are done, you can optionally customize your prompt.
+
+[Installation Instructions](https://github.com/bhilburn/powerlevel9k/wiki/Install-Instructions)
+
+1. [Install the Powerlevel9k Theme](https://github.com/bhilburn/powerlevel9k/wiki/Install-Instructions#step-1-install-powerlevel9k)

+
+No configuration is necessary post-installation if you like the default
+settings, but there are plenty of segment customization options available if you
+are interested.
+
+### Prompt Customization
+
+Be sure to check out the wiki page on the additional prompt customization
+options, including color and icon settings: [Stylizing Your Prompt](https://github.com/bhilburn/powerlevel9k/wiki/Stylizing-Your-Prompt)
+
+#### Customizing Prompt Segments
+Customizing your prompt is easy! Select the segments you want to have displayed,
+and then assign them to either the left or right prompt by adding the following
+variables to your `~/.zshrc`.
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_LEFT_PROMPT_ELEMENTS`|`(context dir vcs)`|Segment list for left prompt|
+|`POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS`|`(status root_indicator background_jobs history time)`|Segment list for right prompt|
+
+
+The table above shows the default values, so if you wanted to set these
+variables manually, you would put the following in
+your `~/.zshrc`:
+```zsh
+POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(context dir vcs)
+POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(status root_indicator background_jobs history time)
+```

+---------------------------------------------------------------------------------
+
+
+##### anaconda
+
+This segment shows your active anaconda environment. It relies on either the
+`CONDA_ENV_PATH` or the `CONDA_PREFIX` (depending on the `conda` version)
+environment variable to be set which happens when you properly `source
+activate` an environment.
+
+Special configuration variables:
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_ANACONDA_LEFT_DELIMITER`|"("|The left delimiter just before the environment name.|
+|`POWERLEVEL9K_ANACONDA_RIGHT_DELIMITER`|")"|The right delimiter just after the environment name.|
+
+Additionally the following segment specific parameters can be used to customize
+it: `POWERLEVEL9K_PYTHON_ICON`, `POWERLEVEL9K_ANACONDA_BACKGROUND`, and
+`POWERLEVEL9K_ANACONDA_FOREGROUND`.
+
+##### aws
+
+If you would like to display the [current AWS
+profile](http://docs.aws.amazon.com/cli/latest/userguide/installing.html), add
+the `aws` segment to one of the prompts, and define `AWS_DEFAULT_PROFILE` in
+your `~/.zshrc`:
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`AWS_DEFAULT_PROFILE`|None|Your AWS profile name|
+
+##### background_jobs
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_BACKGROUND_JOBS_VERBOSE`|`true`|If there is more than one background job, this segment will show the number of jobs. Set this to `false` to turn this feature off.|
+`POWERLEVEL9K_BACKGROUND_JOBS_VERBOSE_ALWAYS`|`false`|Always show the jobs count (even if it's zero).|
+
+##### battery
+
+The default settings for this segment will display your current battery status (fails gracefully on
+systems without a battery). It is supported on both OSX and Linux (note that it requires `acpi` on Linux).
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_BATTERY_CHARGING`|`"yellow"`|Color to indicate a charging battery.|
+|`POWERLEVEL9K_BATTERY_CHARGED`|`"green"`|Color to indicate a charged battery.|
+|`POWERLEVEL9K_BATTERY_DISCONNECTED`|`$DEFAULT_COLOR`|Color to indicate absence of battery.|
+|`POWERLEVEL9K_BATTERY_LOW_THRESHOLD`|`10`|Threshold to consider battery level critical.|
+|`POWERLEVEL9K_BATTERY_LOW_COLOR`|`"red"`|Color to indicate critically low charge level.|
+|`POWERLEVEL9K_BATTERY_VERBOSE`|`true`|Display time remaining next to battery level.|
+|`POWERLEVEL9K_BATTERY_HIDE_ABOVE_THRESHOLD`|`unset`|Threshold from which the battery segment should not be displayed.|
+
+Note that you can [modify the `_FOREGROUND`
+color](https://github.com/bhilburn/powerlevel9k/wiki/Stylizing-Your-Prompt#segment-color-customization)
+without affecting the icon color.
+
+You can also change the battery icon automatically depending on the battery
+level. This will override the default battery icon. In order to do this, you
+need to define the `POWERLEVEL9k_BATTERY_STAGES` variable.
+
+
+| Variable                      | Default Value | Description                                                   |
+|-------------------------------|---------------|---------------------------------------------------------------|
+| `POWERLEVEL9K_BATTERY_STAGES` | Unset         | A string or array, which each index indicates a charge level. |
+
+Powerlevel9k will use each index of the string or array as a stage to indicate battery
+charge level, progressing from left to right. You can provide any number of
+stages. The setting below, for example, provides 8 stages for Powerlevel9k to use.
+```zsh
+POWERLEVEL9K_BATTERY_STAGES="▁▂▃▄▅▆▇█"
+```
+
+If you require extra spacing after the icon, you will have to set it as an array,
+since spaces in the string will be used as one of the stages and you will get a
+missing icon. To do this, declare the variable as follows:
+```zsh
+POWERLEVEL9K_BATTERY_STAGES=($'\u2581 ' $'\u2582 ' $'\u2583 ' $'\u2584 ' $'\u2585 ' $'\u2586 ' $'\u2587 ' $'\u2588 ')
+```
+
+Using the array syntax, you can create stages comprised of multiple characters.
+The below setting provides 40 battery stages.
+```zsh
+POWERLEVEL9K_BATTERY_STAGES=(
+   $'▏    ▏' $'▎    ▏' $'▍    ▏' $'▌    ▏' $'▋    ▏' $'▊    ▏' $'▉    ▏' $'█    ▏'
+   $'█▏   ▏' $'█▎   ▏' $'█▍   ▏' $'█▌   ▏' $'█▋   ▏' $'█▊   ▏' $'█▉   ▏' $'██   ▏'
+   $'██   ▏' $'██▎  ▏' $'██▍  ▏' $'██▌  ▏' $'██▋  ▏' $'██▊  ▏' $'██▉  ▏' $'███  ▏'
+   $'███  ▏' $'███▎ ▏' $'███▍ ▏' $'███▌ ▏' $'███▋ ▏' $'███▊ ▏' $'███▉ ▏' $'████ ▏'
+   $'████ ▏' $'████▎▏' $'████▍▏' $'████▌▏' $'████▋▏' $'████▊▏' $'████▉▏' $'█████▏' )
+```
+
+You can also change the background of the segment automatically depending on the
+battery level. This will override the following variables:
+`POWERLEVEL9K_BATTERY_CHARGING`, `POWERLEVEL9K_BATTERY_CHARGED`,
+`POWERLEVEL9K_BATTERY_DISCONNECTED`, and `POWERLEVEL9K_BATTERY_LOW_COLOR`. In
+order to do this, define a color array, from low to high, as shown below:
+```zsh
+POWERLEVEL9K_BATTERY_LEVEL_BACKGROUND=(red1 orangered1 darkorange orange1 gold1 yellow1 yellow2 greenyellow chartreuse1 chartreuse2 green1)
+```
+
+As with the battery stages, you can use any number of colors and Powerlevel9k
+will automatically use all of them appropriately.
+
+Some example settings:
+
+| Brightness     | Possible Array                                                                                                |
+|----------------|---------------------------------------------------------------------------------------------------------------|
+| Bright Colors  | `(red1 orangered1 darkorange orange1 gold1 yellow1 yellow2 greenyellow chartreuse1 chartreuse2 green1)`       |
+| Normal Colors  | `(red3 darkorange3 darkgoldenrod gold3 yellow3 chartreuse2 mediumspringgreen green3 green3 green4 darkgreen)` |
+| Subdued Colors | `(darkred orange4 yellow4 yellow4 chartreuse3 green3 green4 darkgreen)`                                       |
+
+##### chruby
+
+This segment shows the version of Ruby being used when using `chruby` to change your current Ruby stack.
+
+It uses `$RUBY_ENGINE` and `$RUBY_VERSION` as set by `chruby`.
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_CHRUBY_SHOW_ENGINE`|true|Show the currently selected Ruby engine (e.g. `ruby`, `jruby`, `rbx`, etc)
+|`POWERLEVEL9K_CHRUBY_SHOW_VERSION`|true|Shows the currently selected engine's version (e.g. `2.5.1`)
+
+##### command_execution_time
+
+Display the time the previous command took to execute if the time is above
+`POWERLEVEL9K_COMMAND_EXECUTION_TIME_THRESHOLD`. The time is formatted to be
+"human readable", and so scales the units based on the length of execution time.
+If you want more precision, just set the
+`POWERLEVEL9K_COMMAND_EXECUTION_TIME_PRECISION` field.
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_COMMAND_EXECUTION_TIME_THRESHOLD`|3|Threshold above which to print this segment. Can be set to `0` to always print.|
+|`POWERLEVEL9K_COMMAND_EXECUTION_TIME_PRECISION`|2|Number of digits to use in the fractional part of the time value.|
+
+##### custom_command
+
+The `custom_...` segment allows you to turn the output of a custom command into
+a prompt segment. As an example, if you wanted to create a custom segment to
+display your WiFi signal strength, you might define a custom segment called
+`custom_wifi_signal` like this:
+```zsh
+POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(context time battery dir vcs virtualenv custom_wifi_signal)
+POWERLEVEL9K_CUSTOM_WIFI_SIGNAL="echo signal: \$(nmcli device wifi | grep yes | awk '{print \$8}')"
+POWERLEVEL9K_CUSTOM_WIFI_SIGNAL_BACKGROUND="blue"
+POWERLEVEL9K_CUSTOM_WIFI_SIGNAL_FOREGROUND="yellow"
+```
+If you prefer, you can also define the function in your `.zshrc` rather than
+putting it in-line with the variable export, as shown above. Just don't forget
+to invoke your function from your segment! Example code that achieves the same
+result as the above:
+```zsh
+zsh_wifi_signal(){
+    local signal=$(nmcli device wifi | grep yes | awk '{print $8}')
+    local color='%F{yellow}'
+    [[ $signal -gt 75 ]] && color='%F{green}'
+    [[ $signal -lt 50 ]] && color='%F{red}'
+    echo -n "%{$color%}\uf230  $signal%{%f%}" # \uf230 is 
+}
+
+POWERLEVEL9K_CUSTOM_WIFI_SIGNAL="zsh_wifi_signal"
+POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(context time battery dir vcs virtualenv custom_wifi_signal)
+```
+The command, above, gives you the wireless signal segment shown below:
+
+![signal](http://i.imgur.com/hviMATC.png)
+
+You can define as many custom segments as you wish. If you think you have
+a segment that others would find useful, please consider upstreaming it to the
+main theme distribution so that everyone can use it!
+
+##### context
+
+The `context` segment (user@host string) is conditional. By default, it will
+only print if you are not your 'normal' user (including if you are root), or if
+you are SSH'd to a remote host. `SUDO` and `REMOTE_SUDO` states are also available to show whether the current user or remote user has superuser privileges.
+
+To use this feature, make sure the `context` segment is enabled in your prompt
+elements (it is by default), and define a `DEFAULT_USER` in your `~/.zshrc`.
+
+You can customize the `context` segment. For example, you can make it to print the
+full hostname by setting
+
+```
+POWERLEVEL9K_CONTEXT_TEMPLATE="%n@`hostname -f`"
+```
+
+You can set the `POWERLEVEL9K_CONTEXT_HOST_DEPTH` variable to change how the
+hostname is displayed. See [ZSH Manual](http://zsh.sourceforge.net/Doc/Release/Prompt-Expansion.html#Login-information)
+for details. The default is set to %m which will show the hostname up to the first ‘.’
+You can set it to %{N}m where N is an integer to show that many segments of system
+hostname. Setting N to a negative integer will show that many segments from the
+end of the hostname.
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`DEFAULT_USER`|None|Username to consider a "default context" (you can also set `$USER`).|
+|`POWERLEVEL9K_ALWAYS_SHOW_CONTEXT`|false|Always show this segment, including $USER and hostname.|
+|`POWERLEVEL9K_ALWAYS_SHOW_USER`|false|Always show the username, but conditionalize the hostname.|
+|`POWERLEVEL9K_CONTEXT_TEMPLATE`|%n@%m|Default context prompt (username@machine). Refer to the [ZSH Documentation](http://zsh.sourceforge.net/Doc/Release/Prompt-Expansion.html) for all possible expansions, including deeper host depths.|
+
+This segment can have different states. They might help you to visualize your
+different privileges. Read more about styling with states [here](https://github.com/bhilburn/powerlevel9k/wiki/Stylizing-Your-Prompt#special-segment-colors).
+
+| State         | Meaning                                                  |
+|---------------|----------------------------------------------------------|
+| `DEFAULT`     | You are a normal user                                    |
+| `ROOT`        | You are the root user                                    |
+| `SUDO`        | You are using elevated rights                            |
+| `REMOTE_SUDO` | You are SSH'ed into the machine and have elevated rights |
+| `REMOTE`      | You are SSH'ed into the machine                          |
+
+##### date
+
+The `date` segment shows the current system date.
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_DATE_FORMAT`|`%D{%d.%m.%y}`|[ZSH time format](http://zsh.sourceforge.net/Doc/Release/Prompt-Expansion.html#Date-and-time) to use in this segment.|
+
+##### dir
+
+The `dir` segment shows the current working directory. When using the "Awesome
+Powerline" fonts, there are additional glyphs, as well:
+
+| `Compatible` | `Powerline` | `Awesome Powerline` | Situation
+|------------|-----------|-------------------|----------------------------
+| None       | None      | ![](https://cloud.githubusercontent.com/assets/1544760/12183451/40ec4016-b58f-11e5-9b9e-74e2b2f0b8b3.png) | At the root of your home folder |
+| None       | None      | ![](https://cloud.githubusercontent.com/assets/1544760/12369315/8a5d762c-bbf5-11e5-8a20-ca1179f48d6c.png) | Within a subfolder of your home directory |
+| None       | None      | ![](https://cloud.githubusercontent.com/assets/1544760/12183452/40f79286-b58f-11e5-9b8c-ed1343a07b08.png) | Outside of your home folder |
+| None       | None      | ⚙ | Within the `/etc` directory |
+
+To turn off these icons you could set these variables to an empty string.
+```zsh
+POWERLEVEL9K_HOME_ICON=''
+POWERLEVEL9K_HOME_SUB_ICON=''
+POWERLEVEL9K_FOLDER_ICON=''
+POWERLEVEL9K_ETC_ICON=''
+```
+You can limit the output to a certain length by truncating long paths.
+Customizations available are:
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_DIR_PATH_ABSOLUTE`|None|If set to `true`, will use absolute paths instead of home folder abbreviation `~`|
+|`POWERLEVEL9K_SHORTEN_DIR_LENGTH`|`2`|If your shorten strategy, below, is entire directories, this field determines how many directories to leave at the end. If your shorten strategy is by character count, this field determines how many characters to allow per directory string.|
+|`POWERLEVEL9K_SHORTEN_STRATEGY`|None|How the directory strings should be truncated. See the table below for more informations.|
+|`POWERLEVEL9K_SHORTEN_DELIMITER`|`..`|Delimiter to use in truncated strings. This can be any string you choose, including an empty string if you wish to have no delimiter.|
+
+| Strategy Name | Description |
+|---------------|-------------|
+|Default|Truncate whole directories from left. How many is defined by `POWERLEVEL9K_SHORTEN_DIR_LENGTH`|
+|`truncate_absolute_chars`|Truncates an absolute number of characters from the left such that the number of characters that your path displays (with or without `POWERLEVEL9K_SHORTEN_DELIMITER`) is no more than `POWERLEVEL9K_SHORTEN_DIR_LENGTH` + the length of `POWERLEVEL9K_SHORTEN_DELIMITER` |
+|`truncate_middle`|Truncates the middle part of a folder. E.g. you are in a folder named `~/MySuperProjects/AwesomeFiles/BoringOffice`, then it will truncated to `~/MyS..cts/Awe..les/BoringOffice`, if `POWERLEVEL9K_SHORTEN_DIR_LENGTH=3` is also set (controls the amount of characters to be left).|
+|`truncate_from_right`|Just leaves the beginning of a folder name untouched. E.g. your folders will be truncated like so: `/ro../Pr../office`. How many characters will be untouched is controlled by `POWERLEVEL9K_SHORTEN_DIR_LENGTH`.|
+|`truncate_absolute`|Truncates everything exept the last few characters in the path. E.g. if you are in a folder named `~/Projects/powerlevel9k` and you have set `POWERLEVEL9K_SHORTEN_DIR_LENGTH=3`, you will get `..l9k`.|
+|`truncate_to_last`|Truncates everything before the last folder in the path.|
+|`truncate_to_first_and_last`|Truncate middle directories from the path. How many directories will be untouched is controlled by `POWERLEVEL9K_SHORTEN_DIR_LENGTH`. E.g. if you are in a folder named `~/Projects/powerlevel9k` and you have set `POWERLEVEL9K_SHORTEN_DIR_LENGTH=1`, you will get `~/../powerlevel9k`.||
+|`truncate_to_unique`|Parse all parent path components and truncate them to the shortest unique length. If you copy & paste the result to a shell, after hitting `TAB` it should expand to the original path unambiguously.|
+|`truncate_with_package_name`|Search for a `package.json` or `composer.json` and prints the `name` field to abbreviate the directory path. The precedence and/or files could be set by `POWERLEVEL9K_DIR_PACKAGE_FILES=(package.json composer.json)`. If you have [jq](https://stedolan.github.io/jq/) installed, it will dramatically improve the speed of this strategy.|
+|`truncate_with_folder_marker`|Search for a file that is specified by `POWERLEVEL9K_SHORTEN_FOLDER_MARKER` and truncate everything before that (if found, otherwise stop on $HOME and ROOT).|
+
+For example, if you wanted the truncation behavior of the `fish` shell, which
+truncates `/usr/share/plasma` to `/u/s/plasma`, you would use the following:
+```zsh
+POWERLEVEL9K_SHORTEN_DIR_LENGTH=1
+POWERLEVEL9K_SHORTEN_DELIMITER=""
+POWERLEVEL9K_SHORTEN_STRATEGY="truncate_from_right"
+```
+In each case you have to specify the length you want to shorten the directory
+to. So in some cases `POWERLEVEL9K_SHORTEN_DIR_LENGTH` means characters, in
+others whole directories.
+
+The `truncate_with_package_name` strategy gives your directory path relative to the root of your project.  For example, if you have a project inside `$HOME/projects/my-project` with a `package.json` that looks like:
+
+```json
+{
+  "name": "my-cool-project"
+}
+```
+
+The path shown would be `my-cool-project`.  If you navigate to `$HOME/projects/my-project/src`, then the path shown would be `my-cool-project/src`.  Please note that this currently looks for `.git` directory to determine the root of the project.
+
+If you want to customize the directory separator, you could set:
+```zsh
+# Double quotes are important here!
+POWERLEVEL9K_DIR_PATH_SEPARATOR="%F{red} $(print_icon 'LEFT_SUBSEGMENT_SEPARATOR') %F{black}"
+```
+To omit the first character (usually a slash that gets replaced if you set `POWERLEVEL9K_DIR_PATH_SEPARATOR`),
+you could set `POWERLEVEL9K_DIR_OMIT_FIRST_CHARACTER=true`.
+
+You can also customize the leading tilde character when you are in `$HOME` using:
+```zsh
+# Double quotes are important here!
+POWERLEVEL9K_HOME_FOLDER_ABBREVIATION="%F{red} $(print_icon 'HOME_ICON') %F{black}"
+```
+You can also configure the `dir` segment to show when you are in a directory without write permissions, using the variable below.
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_DIR_SHOW_WRITABLE`|`false`|If set to `true` and you are in a directory that you do not have write permissions for, this segment will display a lock icon and enter the `NOT_WRITABLE` state (which can be customized per [our usual process](https://github.com/bhilburn/powerlevel9k/wiki/Stylizing-Your-Prompt#segment-color-customization)). Note that this functionality is also available in a separate segment, `dir_writable`.|
+
+If you want to customize the last directory of the path, you can now set `POWERLEVEL9K_DIR_PATH_HIGHLIGHT_FOREGROUND` to a custom color and/or `POWERLEVEL9K_DIR_PATH_HIGHLIGHT_BOLD=true` to display that part in bold.
+
+You can also color the separator separately by setting the color using `POWERLEVEL9K_DIR_PATH_SEPARATOR_FOREGROUND`.
+
+##### disk_usage
+
+The `disk_usage` segment will show the usage level of the partition that your current working directory resides in. It can be configured with the following variables.
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_DISK_USAGE_ONLY_WARNING`|false|Hide the segment except when usage levels have hit warning or critical levels.|
+|`POWERLEVEL9K_DISK_USAGE_WARNING_LEVEL`|90|The usage level that triggers a warning state.|
+|`POWERLEVEL9K_DISK_USAGE_CRITICAL_LEVEL`|95|The usage level that triggers a critical state.|
+
+##### host
+
+The `host` segment will print the hostname.
+
+You can set the `POWERLEVEL9K_HOST_TEMPLATE` variable to change how the hostname
+is displayed. See (ZSH Manual)[http://zsh.sourceforge.net/Doc/Release/Prompt-Expansion.html#Login-information]
+for details. The default is set to `%m` which will show the hostname up to the
+first `.`. You can set it to `%{N}m` where N is an integer to show that many
+segments of system hostname. Setting `N` to a negative integer will show that many
+segments from the end of the hostname.
+
+```
+POWERLEVEL9K_HOST_TEMPLATE="%2m"
+```
+
+By default, LOCAL hosts will show the host icon and remote hosts will show the SSH icon. You can override them by setting
+```
+POWERLEVEL9K_HOST_ICON="\uF109 "
+POWERLEVEL9K_SSH_ICON="\uF489 "
+```
+
+
+##### ip
+
+This segment tries to examine all currently used network interfaces and prints
+the first address it finds.  In the case that this is not the right NIC, you can
+specify the correct network interface by setting:
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_IP_INTERFACE`|None|The NIC for which you wish to display the IP address. Example: `eth0`.|
+
+##### vpn_ip
+
+This segment tries to extract the VPN related IP addresses from nmcli, based on the NIC type:
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_VPN_IP_INTERFACE`|`tun`|The VPN interface.|
+
+##### public_ip
+
+This segment will display your public IP address. There are several methods of obtaining this
+information and by default it will try all of them starting with the most efficient. You can
+also specify which method you would like it to use. The methods available are dig using opendns,
+curl, or wget. The host used for wget and curl is http://ident.me by default but can be set to
+another host if you prefer.
+
+If you activate a VPN, the icon for this segment will change to the defined VPN icon.
+
+The public_ip segment will attempt to update your public IP address every 5 minutes by default(also
+configurable by the user). If you lose connection your cached IP address will be displayed until
+your timeout expires at which point every time your prompt is generated a new attempt will be made.
+Until an IP is successfully pulled the value of $POWERLEVEL9K_PUBLIC_IP_NONE will be displayed for
+this segment. If this value is empty(the default)and $POWERLEVEL9K_PUBLIC_IP_FILE is empty the
+segment will not be displayed.
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_PUBLIC_IP_FILE`|'/tmp/p9k_public_ip'|This is the file your public IP is cached in.|
+|`POWERLEVEL9K_PUBLIC_IP_HOST`|'http://ident.me'|This is the default host to get your public IP.|
+|`POWERLEVEL9K_PUBLIC_IP_TIMEOUT`|300|The amount of time in seconds between refreshing your cached IP.|
+|`POWERLEVEL9K_PUBLIC_IP_METHODS`|(dig curl wget)| These methods in that order are used to refresh your IP.|
+|`POWERLEVEL9K_PUBLIC_IP_NONE`|None|The string displayed when an IP was not obtained|
+
+##### load
+
+Displays one of your load averages with appropriate state coloring. The thresholds are:
+- `0.7 * NUM_CORES <`: critical
+- `0.5 * NUM_CORES <`: warning
+- `less`: normal
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_LOAD_WHICH`|5|Which average to show. Possible values: 1, 5 or 15|
+
+##### newline
+
+Puts a newline in your prompt so you can continue using segments on the next
+line. This allows you to use segments on both lines, unlike
+`POWERLEVEL9K_PROMPT_ON_NEWLINE`, which simply separates segments from the
+prompt itself.
+
+This only works on the left side.  On the right side it does nothing.
+
+##### nodeenv
+
+Shows the currently used [nodeenv](https://github.com/ekalinin/nodeenv). To avoid
+Nodeenvs activate command from interfering with Powerlevel9k, you should set
+`NODE_VIRTUAL_ENV_DISABLE_PROMPT=1` in your `~/.zshrc`.
+
+##### rbenv
+
+This segment shows the version of Ruby being used when using `rbenv` to change your current Ruby stack.
+
+It figures out the version being used by taking the output of the `rbenv version-name` command.
+
+* If `rbenv` is not in $PATH, nothing will be shown.
+* By default, if the current local Ruby version is the same as the global Ruby version, nothing will be shown. See the configuration variable, below, to modify this behavior.
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_RBENV_PROMPT_ALWAYS_SHOW`|`false`|Set to true if you wish to show the rbenv segment even if the current Ruby version is the same as the global Ruby version|
+
+##### pyenv
+
+This segment shows the version of Python being used when using `pyenv` to change your current Python stack.
+
+The `PYENV_VERSION` environment variable will be used if specified. Otherwise it figures out the version being used by taking the output of the `pyenv version-name` command.
+
+* If `pyenv` is not in $PATH, nothing will be shown.
+* If the current Python version is the same as the global Python version, nothing will be shown.
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_PYENV_PROMPT_ALWAYS_SHOW`|`false`|Set to true if you wish to show the pyenv segment even if the current Python version is the same as the global Python version|
+
+##### rspec_stats
+
+See [Unit Test Ratios](#unit-test-ratios), below.
+
+##### status
+
+This segment shows the return code of the last command.
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_STATUS_CROSS`|`false`|Set to true if you wish not to show the error code when the last command returned an error and optionally hide this segment when the last command completed successfully by setting `POWERLEVEL9K_STATUS_OK` to false.|
+|`POWERLEVEL9K_STATUS_OK`|`true`|Set to true if you wish to show this segment when the last command completed successfully, false to hide it.|
+|`POWERLEVEL9K_STATUS_SHOW_PIPESTATUS`|`true`|Set to true if you wish to show the exit status for all piped commands.|
+|`POWERLEVEL9K_STATUS_HIDE_SIGNAME`|`false`|Set to true return the raw exit code (`1-255`).  When set to false, values over 128 are shown as `SIGNAME(-n)` (e.g. `KILL(-9)`)|
+
+##### ram
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_RAM_ELEMENTS`|Both|Specify `ram_free` or `swap_used` to only show one or the other rather than both.|
+
+##### symfony2_tests
+
+See [Unit Test Ratios](#unit-test-ratios), below.
+
+##### time
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_TIME_FORMAT`|`'H:M:S'`|ZSH time format to use in this segment.|
+
+As an example, if you wanted a reversed time format, you would use this:
+```zsh
+# Reversed time format
+POWERLEVEL9K_TIME_FORMAT='%D{%S:%M:%H}'
+```
+If you are using an "Awesome Powerline Font", you can add a time symbol to this
+segment, as well:
+```zsh
+# Output time, date, and a symbol from the "Awesome Powerline Font" set
+POWERLEVEL9K_TIME_FORMAT="%D{%H:%M:%S \uE868  %d.%m.%y}"
+```
+##### user
+
+The `user` segment will print the username.
+
+You can also override the icons by setting:
+
+```
+POWERLEVEL9K_USER_ICON="\uF415" # 
+POWERLEVEL9K_ROOT_ICON="#"
+POWERLEVEL9K_SUDO_ICON=$'\uF09C' # 
+```
+
+| Variable | Default Value | Description |

+
+##### vcs
+
+By default, the `vcs` segment will provide quite a bit of information. Further
+customization is provided via:
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_HIDE_BRANCH_ICON`|`false`|Set to `true` to hide the branch icon from the segment.|

+
+##### vcs truncation
+
+You can limit the branch name to a certain length by truncating long names.
+Customizations available are:
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_VCS_SHORTEN_LENGTH`|None|This field determines how many characters to show.|
+|`POWERLEVEL9K_VCS_SHORTEN_MIN_LENGTH`|None|This field determines minimum branch length. Branch name will be truncated if its length greater than this field.|
+|`POWERLEVEL9K_VCS_SHORTEN_STRATEGY`|None|This field determines how branch name should be truncated. See the table below for more information.|
+|`POWERLEVEL9K_SHORTEN_DELIMITER`|`...`|Delimiter to use in truncated strings. This can be any string you choose, including an empty string if you wish to have no delimiter.|
+
+| Strategy Name | Description |
+|---------------|-------------|
+|`truncate_middle`|Truncates the middle part of a branch. E.g. branch name is `1234-super_super_long_branch_name`, then it will truncated to `1234-..._name`, if `POWERLEVEL9K_VCS_SHORTEN_LENGTH=5` is also set (controls the amount of characters to be left).|
+|`truncate_from_right`|Just leaves the beginning of a branch name untouched. E.g. branch name will be truncated like so: `1234-...`. How many characters will be untouched is controlled by `POWERLEVEL9K_VCS_SHORTEN_LENGTH`.|
+
+For example, if you want to truncate `1234-super_super_long_branch_name` to `1234-..` and don't do it with `development`:
+```zsh
+POWERLEVEL9K_VCS_SHORTEN_LENGTH=4
+POWERLEVEL9K_VCS_SHORTEN_MIN_LENGTH=11
+POWERLEVEL9K_VCS_SHORTEN_STRATEGY="truncate_from_right"
+POWERLEVEL9K_VCS_SHORTEN_DELIMITER=".."
+```
+
+##### vi_mode
+
+This segment shows ZSH's current input mode. Note that this is only useful if
+you are using the [ZSH Line Editor](http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html)
+(VI mode).  You can enable this either by `.zshrc` configuration or using a plugin, like
+[Oh-My-Zsh's vi-mode plugin](https://github.com/robbyrussell/oh-my-zsh/blob/master/plugins/vi-mode/vi-mode.plugin.zsh).
+
+| Variable | Default Value | Description |
+|----------|---------------|-------------|
+|`POWERLEVEL9K_VI_INSERT_MODE_STRING`|`"INSERT"`|String to display while in 'Insert' mode.|
+|`POWERLEVEL9K_VI_COMMAND_MODE_STRING`|`"NORMAL"`|String to display while in 'Command' mode.|
+
+To hide the segment entirely when in `INSERT` mode, set `POWERLEVEL9K_VI_INSERT_MODE_STRING=''`
+
+##### virtualenv
+
+This segment shows your Python [VirtualEnv](https://virtualenv.pypa.io/en/latest/). To avoid
+VirtualEnvs activate command from interfering with Powerlevel9k, you should set
+`VIRTUAL_ENV_DISABLE_PROMPT=1` in your `~/.zshrc`.
+
+#### Unit Test Ratios
+
+The `symfony2_tests` and `rspec_stats` segments both show a ratio of "real"
+classes vs test classes in your source code. This is just a very simple ratio,
+and does not show your code coverage or any sophisticated stats. All this does
+is count your source files and test files, and calculate the ratio between them.
+Just enough to give you a quick overview about the test situation of the project
+you are dealing with.
+
+### Disabling / Enabling Powerlevel9k
+
+You can disable P9k and return to a very basic prompt at any time simply by
+calling:
+
+```zsh
+$ prompt_powerlevel9k_teardown
+```
+
+You can then re-enable it by calling:
+
+```zsh
+$ prompt_powerlevel9k_setup
+```

+# Tests
+
+## Automated Tests
+
+The Unit-Tests do not follow exactly the file structure of Powerlevel9k itself,
+but we try to reflect the structure as much as possible. All tests are located
+under `test/`. Segment specific tests under `test/segments/` (one file per
+segment).
+
+### Installation
+
+In order to execute the tests you need to install `shunit2`, which is a
+submodule. To install the submodule, you can execute 
+`git submodule init && git submodule update`.
+
+### Executing tests
+
+The tests are shell scripts on their own. So you can execute them right away.
+To execute all tests you could just execute `./test/suite.spec`.
+
+### General Test Structure
+
+The tests usually have a `setUp()` function which is executed before every
+test function. Speaking of, test functions must be prefixed with `test`. In
+the tests, you can do [different Assertions](https://github.com/kward/shunit2#-asserts).
+It is always a good idea to mock the program you want to test (just have a
+look at other tests), so that the testrunner does not have to have all
+programs installed.
+
+### Travis
+
+We use [Travis](https://travis-ci.org/) for Continuous Integration. This
+service executes our tests after every push. For now, we need to tell travis
+where to find the tests, which is what happens in the `.travis.yml` file.
+
+## Manual Testing
+
+If unit tests are not sufficient (e.g. you have an issue with your prompt that
+occurs only in a specific ZSH framework) then you can use either Docker or
+or our Vagrant.
+
+### Docker
+
+This is the easiest to use _if_ you have Docker already installed and running.
+
+The command `./test-in-docker` should make it fairly easy to get into a running
+container with the framework of your choice.
+
+Examples:
+
+``` zsh
+# Test Antigen with the oldest version of ZSH
+$ ./test-in-docker antigen
+```
+
+``` zsh
+# Test Prezto with ZSH version 5.2
+$ ./test-in-docker --zsh 5.2 prezto
+```
+
+You can get Docker at <https://www.docker.com/community-edition>.
+
+**Note:** Not all frameworks work with all versions of ZSH (or the underlying OS).
+
+### Vagrant
+
+Currently there are two test VMs. `test-vm` is an Ubuntu machine with several
+pre-installed ZSH frameworks. And there is `test-bsd-vm` which is a FreeBSD!
+For how to run the machines see [here](test-vm/README.md).
