How to handle polkit policy file translations?

[buhtz]

Hello,

does anyone has a good tool (chain) to handle translatable strings in *.policy files owned by polkit?

My idea is to create a pot file of that strings, let translators create there language specific po files. To my knowledge polkit does use the gettext domain and ask the system via gettext for a translation of existing strings.

Here is an example of the XML based source using "backintime" as gettext-domain:

  <action id="net.launchpad.backintime.qtgui">
    <message gettext-domain="backintime">Authentication is required to run Back In Time as root.</message>
    <description gettext-domain="backintime">Start Back In Time GUI as root.</description>
    <defaults>
      <allow_any>auth_admin</allow_any>
      <allow_inactive>auth_admin</allow_inactive>
      <allow_active>auth_admin_keep</allow_active>
    </defaults>
    <annotate key="org.freedesktop.policykit.exec.path">/usr/bin/backintime-qt</annotate>
    <annotate key="org.freedesktop.policykit.exec.allow_gui">true</annotate>
  </action>

I checked the gettext tools and po4a. They don't fit.

I can only imagine a self written script (e.g. Python using polib or dealing with plain text files). But I want to prevent that and assuming there are others out their with the same problems and maybe solutions.

Thanks
Christian
