Access the translations within a helper function

[lorezyra]

How should one use i18n inside a helper function?

Ideally, I'd like to use the __() function call to get the translated text from the language files.
I'm building a theme and using helpers to build the HTML instead of embedding all the logic in the EJS template. What am I missing?

Use this.__. For example:

hexo.extend.helper.register('post_edit', function(src) {
  const { post_edit } = this.theme;
  if (!post_edit.enable) return '';
  return this.next_url(post_edit.url + src, '<i class="fa fa-pen-nib"></i>', {
    class: 'post-edit-link',
    title: this.__('post.edit')
  });
});

I've tried both this.__('post.edit') and __('post.edit'). I still get the error: "__ is not a function". Maybe I'm too sleepy to figure this out right now. Time for 🛌💤. Perhaps, I'm not in the right scope.

Yeah, that was my problem - Scope. Thanks. It works.
