# Config file for Powerlevel10k with the style of Pure (https://github.com/sindresorhus/pure).
#
# 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.
# Temporarily change options.

# 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`.

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 config run
`xrdb ~/.Xresources` to reload it. The new config is applied to all new terminals.
- **xterm**: Create or open `~/.Xresources` and add the following line to it:
```text
xterm*faceName: MesloLGS NF
```
After changing the config run `xrdb ~/.Xresources` to reload it. The new config is applied to
all new terminals.
- Crostini (Linux on Chrome OS): Open
chrome-untrusted://terminal/html/nassh_preferences_editor.html, set *Text font family* to
`'MesloLGS NF'` (including the quotes) and *Custom CSS (inline text)* to the following:
```css
@font-face {
font-family: "MesloLGS NF";
src: url("https://raw.githubusercontent.com/romkatv/powerlevel10k-media/master/MesloLGS%20NF%20Regular.ttf");
font-weight: normal;
font-style: normal;
}
@font-face {
font-family: "MesloLGS NF";
src: url("https://raw.githubusercontent.com/romkatv/powerlevel10k-media/master/MesloLGS%20NF%20Bold.ttf");
font-weight: bold;
font-style: normal;
}
@font-face {
font-family: "MesloLGS NF";
src: url("https://raw.githubusercontent.com/romkatv/powerlevel10k-media/master/MesloLGS%20NF%20Italic.ttf");
font-weight: normal;
font-style: italic;
}
@font-face {
font-family: "MesloLGS NF";
src: url("https://raw.githubusercontent.com/romkatv/powerlevel10k-media/master/MesloLGS%20NF%20Bold%20Italic.ttf");
font-weight: bold;
font-style: italic;
}
```
**_CAVEAT_**: If you open the normal terminal preferences these settings will be overwritten.
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
**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. If you install Powerlevel10k, you don't need to
install gitstatus.
![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
```
Users in 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 ~/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
```
Users in 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.
```bash
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:
| 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 |
If you'd like to change the format of git status, or want to have greater control over the
process of assembling `PS1`, you can copy and modify parts of
[gitstatus.prompt.sh](gitstatus.prompt.sh) instead of sourcing the script. Your `~/.bashrc` might
look something like this:
```bash
source ~/gitstatus/gitstatus.plugin.sh
function my_set_prompt() {
PS1='\w'
if gitstatus_query && [[ "$VCS_STATUS_RESULT" == ok-sync ]]; then
if [[ -n "$VCS_STATUS_LOCAL_BRANCH" ]]; then
PS1+=" ${VCS_STATUS_LOCAL_BRANCH//\\/\\\\}" # escape backslash
else
PS1+=" @${VCS_STATUS_COMMIT//\\/\\\\}" # escape backslash
fi
(( VCS_STATUS_HAS_STAGED" )) && PS1+='+'
(( VCS_STATUS_HAS_UNSTAGED" )) && PS1+='!'
(( VCS_STATUS_HAS_UNTRACKED" )) && PS1+='?'
fi
PS1+='\n\$ '
shopt -u promptvars # disable expansion of '$(...)' and the like
}
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 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.

# 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.
| version | optimization | score |
|---------|--------------------------------------|----------:|
| v1 | baseline | 100.0 |
| v2 | avoid heap allocations | 112.7 |
| **v3** | **open directories with `openat()`** | **116.2** |
## 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 |
| v2 | avoid heap allocations | 112.7 |
| 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.

Fast and respectably arcane.
## 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.

Usage: install [-s KERNEL] [-m ARCH] [-d DIR] [-p CMD] [-e ERRFD] [-f|-n] [-- CMD [ARG]...]
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)

#!/usr/bin/env zsh
#
# 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
# AcceptEnv TERM LANG LC_*
# PermitRootLogin no
# AllowTcpForwarding no
# AllowAgentForwarding no
# AllowStreamLocalForwarding no
# AuthenticationMethods publickey
# END
# service ssh --full-restart
# - Add your public ssh key to ~/.ssh/authorized_keys.
# - Make `sshd` start when Windows boots.

battery: use the same technique as in vpn_ip to avoid reset=2.
---
implement fake gitstatus api on top of vcs_info (or plain git?) + worker and use it if there is no
gitstatus.
---
- call vcs_info on worker. the tricky question is what to display while "loading".
---
- add _SHOW_SYSTEM to all *env segments.
---
- support states in SHOW_ON_COMMAND: POWERLEVEL9K_SEGMENT_STATE_SHOW_ON_COMMAND='...'
---
add POWERLEVEL9K_${SEGMENT}_${STATE}_SHOW_IN_DIR='pwd_pattern'; implement the same way as
SHOW_ON_UPGLOB. how should it interact with POWERLEVEL9K_${SEGMENT}_DISABLED_DIR_PATTERN?
---
add `p10k upglob`; returns 0 on match and sets REPLY to the directory where match was found.
---
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.
the replacement parameter's value is `…/` (with a slash) to allow for `x/anchor/y/anchor`.
---
- add to faq: how do i display an environment variable in prompt? link it from "extensible"
---
- add to faq: how do i display an icon in prompt? link it from "extensible"
---
- add root_indicator to config templates
---
- test chruby and add it to config templates
---
- add ssh to config templates
---
- add swift version to config templates; see if there is a good pattern for PROJECT_ONLY
---
- 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.
