#!/usr/bin/env bash
# This script is part of RawTherapee.
#
# This Bash4 script checks whether each key in "default" is used in
# a .cc or .h file. Those that are not are printed to screen, and the
# user is asked if they should be deleted from all language files.
#
# Keys in commented-out sections "//" are ignored.
#
# Some concatenated keys are ignored, these need to be added to the list manually:
# HISTORY_MSG_
# EXTPROGTARGET_
# FILEBROWSER_POPUPRANK
# FILEBROWSER_POPUPCOLORLABEL
# SAMPLEFORMAT_
# TP_RAW_[demosaic_method]
#
# The script can also clean up already-translated files by removing keys which
# do not exist in default.
#
# Run the script from the project root:
# ./tools/generateUnusedKeys
#
# Run ./tools/generateTranslationDiffs before and after running this script.
# Double-check the deletion before committing.
#
# Blame DrSlony
