xgettext

Extract gettext strings from code files. More information: https://www.gnu.org/software/gettext/manual/html_node/xgettext-Invocation.html.

  • Scan file and output strings to messages.po:

xgettext {{path/to/input_file}}

  • Use a different output filename:

xgettext --output {{path/to/output_file}} {{path/to/input_file}}

  • Append new strings to an existing file:

xgettext --join-existing --output {{path/to/output_file}} {{path/to/input_file}}

  • Don't add a header containing metadata to the output file:

xgettext --omit-header {{path/to/input_file}}
