translations.sh

#!/usr/bin/env bash

# This script pulls translation files from Transifex
# Files are stored there in two big files, one for xivoclient, one for baselib
# We duplicate the big files for every .ts file we need, then we use lupdate to
# strip them down.

# To add a new translation :
# find . -name '*.pro' -exec sed -i -e 's|^TRANSLATIONS += $${\?ROOT_DIR}\?/i18n/\(.*\)_en.ts|\0\nTRANSLATIONS += $$ROOT_DIR/i18n/\1_it.ts|' {} \;
# find . -name '*.qrc' -exec sed -i -e 's|^\( *\)<file>\(.*\)obj/\(.*\)_fr.qm</file>|\0\n\1<file>\2obj/\3_de.qm</file>|' {} \;
