### INSTRUCTIONS ###

# Place the code to file "pre-commit" (no extension) and add it to the one of
# the following locations:
# 1) Repository hooks folder - C:\Path\To\Repository\.git\hooks
# 2) User profile template   - C:\Users\<USER>\.git\templates\hooks
# 3) Global shared templates - C:\Program Files (x86)\Git\share\git-core\templates\hooks
#
# The hooks from user profile or from shared templates are copied from there
# each time you create or clone new repository.

### SETTINGS ###

# Path to the php.exe
$php_exe = "C:\php\php.exe";

# Path to the phpcs
$php_cs = "phpcs";

# Extensions of the PHP files
$php_ext = 'php|module|inc|install|test|profile|theme|txt|class';

# Flag, if set to $true git will unstage all files with errors, set to $false to disable
$unstage_on_error = 0;
