pre-commit

#
# Pre commit hook to run phpcs and abort commits on failures or warnings
#
# To use, copy or link to the .git/hooks folder of your repository.
#
# This simple script:
# 1. Determins the width of the current console, so the report is full-width
# 2. Determins which commit to diff against (to know what is being commited) - 
#    using a fictional commit if it's the first commit.
# 3. Skip files which don't exist or are not php files
# 4. If the commit is multiple files run in summary mode, otherwise show details
#
# If phpcs returns a none-zero value (which means errors or warnings where found)
# The commit will be aborted. A developer can override this pre-commit hook and
# thus still commit despite the errors or warnings raised with the command:
#
# 		git commit --no-verify <same args as before>
