# Fetch the Transifex translations for Calamares and incorporate them
# into the source tree, adding commits of the different files.

### INITIAL SETUP
#
# This stuff needs to be done once; in a real CI environment where it
# runs regularly in a container, the setup needs to be done when
# creating the container.
#
#
# cp ~/jenkins-master/.transifexrc ~  # Transifex user settings
# cp ~/jenkins-master/.gitconfig ~    # Git config, user settings
# cp -R ~/jenkins-master/.ssh ~       # SSH, presumably for github
#
# cd "$WORKSPACE"
# git config --global http.sslVerify false

test -f "CMakeLists.txt" || { echo "! Not at Calamares top-level" ; exit 1 ; }
test -f ".tx/config" || { echo "! Not at Calamares top-level" ; exit 1 ; }
test -f "calamares.desktop" || { echo "! Not at Calamares top-level" ; exit 1 ; }

### FETCH TRANSLATIONS
#
# Use Transifex client to get translations; this depends on the
# .tx/config file to locate files, and overwrites them in the
# filesystem with new (merged) translations.
export QT_SELECT=5
tx pull --force --source --all

### COMMIT TRANSLATIONS
#
# Produce multiple commits (for the various parts of the i18n
# infrastructure used by Calamares) of the updated translations.
# Try to be a little smart about not committing trivial changes.

# Who is credited with these CI commits
AUTHOR="--author='Calamares CI <groot@kde.org>'"
# Message to put after the module name
BOILERPLATE="Automatic merge of Transifex translations"
