Tool for maintenance of .po and .pot files

Normally, the i18n-related files contain for each translatable string a

reference to all the source code locations where this string is found. This

meta data is useful for translators to assess how strings are used, but is not

relevant for normal development nor for running Kallithea. Such meta data, or

derived data like kallithea.pot, will inherently be outdated, and create

unnecessary churn and repository growth, making it harder to spot actual and

important changes.

    If a .pot file is specified, the po files will instead be updated by

    running GNU msgmerge with this .pot file, thus updating source code

    references and preserving comments and outdated translations.

    Add the following to your user or repository-specific .hgrc file to use it:

        [merge-tools]

        i18n.executable = /path/to/scripts/i18n

        i18n.args = normalized-merge $local $base $other $output

    and then invoke merge/rebase/graft with the additional argument '--tool i18n'.

    """

    i18n_utils._normalize_po_file(other, merge_pot_file=merge_pot_file, strip=strip)

    # simplemerge will write markers to 'local' if it fails, keep a copy without markers
