### 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:\Program Files (x86)\Zend\ZendServer\bin\php.exe";
# Extensions of the PHP files 
$php_ext = "php|engine|theme|install|inc|module|test"
# Flag, if set to 1 git will unstage all files with errors, se to 0 to disable
$unstage_on_error = 0;
