We should automate some of the checks that people perform during i18n review of our code.

Below I've included one by Erik Bernhardson that checks for missing i18n documentation.[2] The maintenance/language directory has several check* scripts[1];  I couldn't get its checkExtension.php to run, it references a $wgTranslateAC that was removed from extension Translate in 4651bd97f.

[2] This is in the form of a git hook but I hope it's straightforward to turn it into a Jenkins job.  (Its assumption that MyExtension has a MyExtension.i18n.php file is true for 150 of the 180 extensions I have locally.)

In .git/hooks/pre-review put the following:

    #!/usr/bin/env php
    <?php

    // This file must have the executable flag set to work as a hook

    // A hooks path is always /path/to/repo/.git/hooks/hook-name
    $repo = dirname( dirname( dirname( realpath( $argv[0] ) ) ) );

    include "$repo/Flow.i18n.php";

    $missing = array_diff( array_keys( $messages['en'] ), array_keys( $messages['qqq'] ) );
    if ( $missing ) {
            echo "Missing i18n messages:\n\t" . implode( "\n\t", $missing ) . "\n";
            exit( 1 );
    }

chmod +x the new file.
