Clone repository to a bare repository.
Return information about git repository.
Information include: - Path of the git directory - Repository name - Current/active branch
Will return status 412 if working directory is not inside a git repository. Will return status 500 on errors, e.g. if git command cannot recognize the repository.
git
Run post-commit hook.
Basically the same as:
% .git/hooks/post-commit
except can be done anywhere inside git repo.
Run pre-commit hook.
% .git/hooks/pre-commit
Alias for run-hook.
% .git/hooks/<hook-name>
except can be done anywhere inside git repo and provides tab completion.
Run a hook.
* marks required options.
*
Select subcommand.
This is useful if a default subcommand exists, where that subcommand will be chosen if user does not specify another explicitly.
Set path to configuration file.
Can actually be specified multiple times to instruct application to read from multiple configuration files (and merge them).
Set configuration profile to use.
A single configuration file can contain profiles, i.e. alternative sets of values that can be selected. For example:
[profile=dev] username=foo pass=beaver [profile=production] username=bar pass=honey
When you specify --config-profile=dev, username will be set to foo and password to beaver. When you specify --config-profile=production, username will be set to bar and password to honey.
--config-profile=dev
username
foo
password
beaver
--config-profile=production
bar
honey
Choose output format, e.g. json, text.
Default value:
undef
Output can be displayed in multiple formats, and a suitable default format is chosen depending on the application and/or whether output destination is interactive terminal (i.e. whether output is piped). This option specifically chooses an output format.
Display help message and exit.
Set output format to json.
When outputing as JSON, strip result envelope.
0
By default, when outputing as JSON, the full enveloped result is returned, e.g.:
[200,"OK",[1,2,3],{"func.extra"=>4}]
The reason is so you can get the status (1st element), status message (2nd element) as well as result metadata/extra result (4th element) instead of just the result (3rd element). However, sometimes you want just the result, e.g. when you want to pipe the result for more post-processing. In this case you can use --naked-res so you just get:
--naked-res
[1,2,3]
Do not use any configuration file.
If you specify --no-config, the application will not read any configuration file.
--no-config
Do not read environment for default options.
If you specify --no-env, the application wil not read any environment variable.
--no-env
Filter output through a pager.
This option will pipe the output to a specified pager program. If pager program is not specified, a suitable default e.g. less is chosen.
less
List available subcommands.
Display program's version and exit.
View output using a viewer.
This option will first save the output to a temporary file, then open a viewer program to view the temporary file. If a viewer program is not chosen, a suitable default, e.g. the browser, is chosen.
A directory inside git repo.
If not specified, will assume current directory is inside git repository and will search .git upwards.
.git
Target repo directory.
If not specified, defaults to $repodir.bare/.
$repodir.bare/
Hook name, e.g. post-commit.
Can also be specified as the 1st command-line argument.
This script has shell tab completion capability with support for several shells.
To activate bash completion for this script, put:
complete -C gu gu
in your bash startup (e.g. ~/.bashrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.
It is recommended, however, that you install modules using cpanm-shcompgen which can activate shell completion for scripts immediately.
To activate tcsh completion for this script, put:
complete gu 'p/*/`gu`/'
in your tcsh startup (e.g. ~/.tcshrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.
It is also recommended to install shcompgen (see above).
For fish and zsh, install shcompgen as described above.
This script can read configuration files. Configuration files are in the format of IOD, which is basically INI with some extra features.
By default, these names are searched for configuration filenames (can be changed using --config-path): /home/s1/.config/gLtTcp7C8L.conf, /home/s1/gLtTcp7C8L.conf, or /etc/gLtTcp7C8L.conf.
--config-path
All found files will be read and merged.
To disable searching for configuration files, pass --no-config.
To put configuration for a certain subcommand only, use a section name like [subcommand=NAME] or [SOMESECTION subcommand=NAME].
[subcommand=NAME]
[SOMESECTION subcommand=NAME]
You can put multiple profiles in a single file by using section names like [profile=SOMENAME] or [SOMESECTION profile=SOMENAME] or [subcommand=SUBCOMMAND_NAME profile=SOMENAME] or [SOMESECTION subcommand=SUBCOMMAND_NAME profile=SOMENAME]. Those sections will only be read if you specify the matching --config-profile SOMENAME.
[profile=SOMENAME]
[SOMESECTION profile=SOMENAME]
[subcommand=SUBCOMMAND_NAME profile=SOMENAME]
[SOMESECTION subcommand=SUBCOMMAND_NAME profile=SOMENAME]
--config-profile SOMENAME
You can also put configuration for multiple programs inside a single file, and use filter program=NAME in section names, e.g. [program=NAME ...] or [SOMESECTION program=NAME]. The section will then only be used when the reading program matches.
program=NAME
[program=NAME ...]
[SOMESECTION program=NAME]
You can also filter a section by environment variable using the filter env=CONDITION in section names. For example if you only want a section to be read if a certain environment variable is true: [env=SOMEVAR ...] or [SOMESECTION env=SOMEVAR ...]. If you only want a section to be read when the value of an environment variable equals some string: [env=HOSTNAME=blink ...] or [SOMESECTION env=HOSTNAME=blink ...]. If you only want a section to be read when the value of an environment variable does not equal some string: [env=HOSTNAME!=blink ...] or [SOMESECTION env=HOSTNAME!=blink ...]. If you only want a section to be read when the value of an environment variable includes some string: [env=HOSTNAME*=server ...] or [SOMESECTION env=HOSTNAME*=server ...]. If you only want a section to be read when the value of an environment variable does not include some string: [env=HOSTNAME!*=server ...] or [SOMESECTION env=HOSTNAME!*=server ...]. Note that currently due to simplistic parsing, there must not be any whitespace in the value being compared because it marks the beginning of a new section filter or section name.
env=CONDITION
[env=SOMEVAR ...]
[SOMESECTION env=SOMEVAR ...]
[env=HOSTNAME=blink ...]
[SOMESECTION env=HOSTNAME=blink ...]
[env=HOSTNAME!=blink ...]
[SOMESECTION env=HOSTNAME!=blink ...]
[env=HOSTNAME*=server ...]
[SOMESECTION env=HOSTNAME*=server ...]
[env=HOSTNAME!*=server ...]
[SOMESECTION env=HOSTNAME!*=server ...]
To load and configure plugins, you can use either the -plugins parameter (e.g. -plugins=DumpArgs or -plugins=DumpArgs@before_validate_args), or use the [plugin=NAME ...] sections, for example:
-plugins
-plugins=DumpArgs
-plugins=DumpArgs@before_validate_args
[plugin=NAME ...]
[plugin=DumpArgs] -event=before_validate_args -prio=99 [plugin=Foo] -event=after_validate_args arg1=val1 arg2=val2
which is equivalent to setting -plugins=-DumpArgs@before_validate_args@99,-Foo@after_validate_args,arg1,val1,arg2,val2.
-plugins=-DumpArgs@before_validate_args@99,-Foo@after_validate_args,arg1,val1,arg2,val2
List of available configuration parameters:
format (see --format) naked_res (see --naked-res)
dir (see --dir) target_dir (see --target-dir)
dir (see --dir)
dir (see --dir) name (see --name)
Specify additional command-line options.

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.
Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:
% prove -l
If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
