[dokuwiki] [PATCH] Translatable Javascript strings

Hello,

attached you will find a patch that enables translatable string for the
script.js file of plugins.
If you want to use translatable strings, create a file called lang.js in the
lang/en directory of your plugin. The lang.js file has the following
structure:

LANG.addTranslation('plugin_name', {
        key1:'Text1',
        key2:'Text2'
        // etc ...
});

Here is a concrete example for a plugin named "exampleplugin":

LANG.addTranslation('exampleplugin', {
        errmsg:'Wrong foo in bar!'
});

If you put a lang.js file in another language directory, for example
lang/de, the structure is the same and the keys of the default language will
be overwritten - if they exist in the foreign language file. A language file
of a foreign language can't introduce new keys.

Here is an example on how to use a translatable string in your script.js:

alert(LANG.plugins.exampleplugin.errmsg);

Keep in mind that your lang.js files must be UTF-8 encoded.

I would be glad if you could accept this modification.

Greetings,

Gabriel
