pre-commit hook to run the grunt release to ensure that all files static are also committed (runs only if js,less or css have been changed). I assume that all the generated files are stored in static's folder

gistfile1.sh

#!/bin/sh
# stash unstaged changes, run release task, stage release updates and restore stashed files

PATH=$PATH:/usr/local/bin:/usr/local/sbin

NAME=$(git branch | grep '*' | sed 's/* //')

# Run the commit only if we have css,less or js files changed
files=$(git diff --cached --name-only --diff-filter=ACM | grep -E "\.(js|less|css)$")
if [ "$files" = "" ]
then
  exit 0
fi

# don't run on rebase
if [ $NAME != '(no branch)' ]
then
  # first we discard the changes into static
  # as it will be generated by grunt just below
  git checkout static && git stash -q --keep-index
  grunt --no-color release

  RETVAL=$?

  if [ $RETVAL -ne 0 ]
  then
    git stash pop -q
    exit 1
  fi

  # Only add files that are into static
  git add static
  git stash pop -q
fi
