Manage git hooks easily in your composer configuration. This command line tool makes it easy to implement a consistent project-wide usage of git hooks. Specifying hooks in the composer file makes them available for every member of the project team. This provides a consistent environment and behavior for everyone which is great. It is also possible to use to manage git hooks globally for every repository on your computer. That way you have a reliable set of hooks crafted by yourself for every project you choose to work on.
Add a hooks
section to the extra
section of your composer.json
and add the hooks there.
{
"extra": {
"hooks": {
"pre-commit": [
"echo committing as $(git config user.name)",
"php-cs-fixer fix ." // fix style
],
// verify commit message. ex: ABC-123: Fix everything
"commit-msg": "grep -q '[A-Z]+-[0-9]+.*' $1",
"pre-push": [
"php-cs-fixer fix --dry-run ." // check style
"phpunit"
],
"post-merge": "composer install"
"...": "..."
}
}
}
Then install with
composer require --dev pepperfm/composer-git-hooks
This installs the cghooks
binary to your vendor/bin
folder. If this folder is not in your path, you will need to preface every command with vendor/bin/
.
Note: hooks declared in the scripts
or hooks
root sections of composer.json
are no longer supported in v3.
You can also install it globally. This feels much more natural when cghooks
is used with the newly added support for managing global git hooks.
composer global require --dev pepperfm/composer-git-hooks
All commands have global support (besides testing the hooks. Still requires being in the directory with the composer.json
file).
When a hook is a sequence of commands, it can be useful to stop the execution when a command fails.
Specify the impacted hooks in the stop-on-failure
config section.
{
"extra": {
"hooks": {
"config": {
"stop-on-failure": ["pre-push"]
},
"pre-push": [
"php-cs-fixer fix --dry-run --stop-on-violation .",
"phpunit"
],
}
}
}
Always be sure to run the update command after changing the stop-on-failure
config section.
Custom hooks can be added to the custom-hooks
array of the `config section.
{
"extra": {
"hooks": {
"config": {
"custom-hooks": ["pre-flow-feature-start"]
},
"pre-flow-feature-start": [
"echo 'Starting a new feature...'"
]
}
}
}
Always be sure to run the update command after changing the custom-hooks
config section.
Note: config
is not valid custom hook value.
Add a cghooks
script to the scripts
section of your composer.json
file. That way, commands can be run with composer cghooks ${command}
. This is ideal if you would rather not edit your system path.
{
"scripts": {
"cghooks": "vendor/bin/cghooks",
"...": "..."
}
}
Add the following events to your composer.json
file. The cghooks
commands will be run every time the events occur. Go to Composer Command Events for more details about composer's event system.
{
"scripts": {
"post-install-cmd": "cghooks add --ignore-lock",
"post-update-cmd": "cghooks update",
"...": "..."
}
}
All the following commands have to be run either in the same folder as your composer.json
file or by specifying the --git-dir
option to point to a folder with a composer.json
file.
After installation is complete, run cghooks add
to add all the valid git hooks that have been specified in the composer config.
Option | Description | Command |
---|---|---|
no-lock |
Do not create a lock file | cghooks add --no-lock |
ignore-lock |
Add the lock file to .gitignore | cghooks add --ignore-lock |
force-win |
Force windows bash compatibility | cghooks add --force-win |
The lock
file contains a list of all added hooks.
If the --global
flag is used, the hooks will be added globally, and the global git config will also be modified. If no directory is provided, there is a fallback to the current core.hooksPath
in the global config. If that value is not set, it defaults to $COMPOSER_HOME
(this specific fallback only happens for the add
command). It will fail with an error if there is still no path after the fallbacks.
The update command which is run with cghooks update
basically ignores the lock file and tries to add hooks from the composer file. This is similar to what the --force
option for the add
command did. This command is useful if the hooks in the composer.json
file have changed since the first time the hooks were added.
This works similarly when used with --global
except that there is no fallback to $COMPOSER_HOME
if no directory is provided.
Hooks can be easily removed with cghooks remove
. This will remove all the hooks that were specified in the composer config.
Hooks can also be removed by passing them as arguments. The command cghooks remove pre-commit post-commit
which will remove the pre-commit
and post-commit
hooks.
Option | Description | Command |
---|---|---|
force |
Delete hooks without checking the lock file | cghooks remove --force |
CAREFUL: If the lock file was tampered with or the force option was used, hooks that already existed before using this package, but were specified in the composer scripts config will be removed as well. That is, if you had a previous pre-commit
hook, but your current composer config also has a pre-commit
hook, this option will cause the command to remove your initial hook.
This also does not have a fallback to $COMPOSER_HOME
if no directory is provided when used with --global
.
Hooks can be listed with the cghooks list-hooks
command. This basically checks composer config and list the hooks that actually have files.
The following options are common to all commands.
Option | Description | Command |
---|---|---|
git-dir |
Path to git directory | cghooks ${command} --git-dir='/path/to/.git' |
lock-dir |
Path to lock file directory | cghooks ${command} --lock-dir='/path/to/lock' |
global |
Runs the specified command globally | cghooks ${command} --global |
Each command also has a flag -v
to control verbosity for more detailed logs. Currently, only one level is supported.
Hooks can be tested with cghooks ${hook}
before adding them. Example cghooks pre-commit
runs the pre-commit
hook.
