Generating an updated PHP translation file using gettext

readme.md

Simple Instructions:

Run the command.

Explanations:

1. xgettext will parse a file and look for strings which are wrapped in _(). It will output those strings to a .po file for translations (default filename = messages.po).
   • What it looks for varies based on language - see 5.1.6.
2. The find command will cause xgettext to parse all of the files which find returns rather than just parsing a single file.
3. --join-existing will merge the results to an existing message.po file in the same output directory.
   • --join-existing shouldn't be used if a messages.po file doesn't already exist in the location which your output points to.

Invocation documentation for xgettext.

update-translation-file.sh

find /var/www/project/source -iname "*.php" -o -iname "*.phtml" | xargs xgettext --output-dir=/var/www/project/source/application/languages/ --language=PHP --no-wrap --default-domain='translation-template' --copyright-holder='Company' --msgid-bugs-address=support@company.com --join-existing

Running this on OSX, you might need to install gettext:
