Shell script to be used in build phases in xCode, so it will inject git revision and stuff into bundle

xCodeGitRevision.sh

#!/bin/bash
BUILD_NUMBER=`git rev-parse --short HEAD`
git update-index -q --refresh
CHANGES=$(git diff-index --name-only HEAD --)
if [ ! -z "${CHANGES}" ]; then
    BUILD_NUMBER="${BUILD_NUMBER}+"
    if [ "${CONFIGURATION}" == "Debug" ]; then
        git diff --color | tools/ansi2html.sh --bg=dark > gitdiff.html
        cp ${PROJECT_DIR}/gitdiff.html ${BUILT_PRODUCTS_DIR}/${CONTENTS_FOLDER_PATH}
    fi

/usr/libexec/PlistBuddy -c "Set :GitRevision $BUILD_NUMBER" "${TARGET_BUILD_DIR}"/"${INFOPLIST_PATH}"
