Some or all JS files are not respected by potx

[olafgrabienski]

I extracted the language template files of the core and the profiles directory of a Backdrop 1.6.3. site using the potx module via Drush.

When I compared these files at random with a language template file exported otherwise, I noticed that some (or all?) .js files weren't respected by potx.

As an example see core/misc/backdrop.js which seemingly wasn't interpreted by potx although there are relevant language strings in it, for instance Backdrop.t("An AJAX HTTP error occurred.").

replace Drupal.t.

I went ahead and merged my PR at #4. It gets the UI working.

• Enable potx module.
• Visit /admin/config/regional/translate/extract
• Select a module that has calls to either Drupal.t() or Backdrop.t() (both should be detected now).
• Export.
• Get a .pot file downloaded in the browser.

I noticed that while Backdrop.t() calls are now exported, they all are reported as line number "0". But that seems to be the current design of the module that it doesn't track line numbers in JS files. So it's not perfect but it's matching the Drupal module functionality.
