transtest

A basic Drupal 8 module for testing translation within Twig {% trans %} block see t() variable placeholders not appearing to work in Twig {% trans %}

To run the test with this module:

1. Install this module in D8 the normal way
2. Enable the 4 multilingual modules
3. In admin/config/regional/language click Add Language and add Spanish
4. go to [path/to/drupal]/trans-test and then for Spanish [path/to/drupal]/es/trans-test

From the link above:

According to a few sources, the t() variable placeholders are supposed to work in the following way, using a {% trans %} block:

{% set string = '&"<>' %}
{% trans %}
  Escaped: {{ string }}                    <-- default, same as @  (i.e. escape plain text to HTML)
{% endtrans %}
{% trans %}
  Pass-through: {{ string|passthrough }}   <-- same as !  (i.e. insert as is)
{% endtrans %}
{% trans %}
  Placeholder: {{ string|placeholder }}    <-- same as %  (i.e. <em class="placeholder">' . escape plain text to HTML . '</em>')
{% endtrans %}

However, running some tests, I am not able to get this to work.

In the output generated by this module, note that tests 2,3&5 are not supposed to produce translations (and they don't), but that tests 1,4,6,7 should do so; however, only test 1 is producing a translation. None of the tests inside {% trans %}...{% endtrans %} produce translations.

A 2nd thing to note, from looking at the HTML source code, is that for the string '&"<>' the characters are not being escaped (turned into HTML entities), although they might be intended to by tests 1,4,7. (Note that straight Twig does do, this though: {{ string }} ).
