# mass-rename: update source files (gyp lists, #includes) to reflect
# a rename.  Expects "git diff --cached -M" to list a bunch of renames.
#
# To use:
#   1) git mv foo1 bar1; git mv foo2 bar2; etc.
#   2) *without committing*, ./tools/git/mass-rename.sh
#   3) look at git diff (without --cached) to see what the damage is
#   4) commit, then use tools/sort-headers.py to fix #include ordering:
#   for f in $(git diff --name-only origin); do ./tools/sort-headers.py $f; done

DIR="$( cd "$( dirname "$0" )" && pwd )"

# Make the 'read' used in the while loop split only on tabs/newlines.
