#
# Helper function for extracting translatable messages from Calligra/Krita/Kexi source code.
# Usage: kundo2_aware_xgettext <pot-filename-without-path> <source-files-list>
# If there are no messages or the <source-files-list> is empty, the pot file is deleted.
#
# Example usage that creates $podir/myapp.pot file:
# kundo2_aware_xgettext myapp.pot `find . -name \*.cpp -o -name \*.h`
#
function kundo2_aware_xgettext() {
POTFILE="$podir/$1"

if test -n "$*"; then
# we rely on last line being a 'msgstr' signaling that strings has been extracted (a header is always present)
# normally it ends with 'msgstr ""' but if plural it can end with eg 'msgstr[1] ""'
kundo2_aware_xgettext_internal $* | tee "${POTFILE}" | tail -n1 | grep "^msgstr" > /dev/null \
|| rm -f "${POTFILE}" 2> /dev/null
fi
}
# How to unit test:
# export podir=.
# cp init-sample.pot sample.pot
# source krita_xgettext.sh
# add_ctxt_qtundo sample.pot
#
# Then check that all messages in sample.pot have "(qtundo-format)" in msgctxt.
