xgettext

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

• Scan file and output strings to messages.po:

xgettext {{path/to/input_file}}

• Use a different output filename:

xgettext {{[-o|--output]}} {{path/to/output_file}} {{path/to/input_file}}

• Append new strings to an existing file:

xgettext {{[-j|--join-existing]}} {{[-o|--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}}

• Display help:

xgettext {{[-h|--help]}}
