[WIP] Twig extension testing, fix nontype collections

[dbu]

this tries to address #37

unfortunately, i still don't know how to really handle string tags and would need somebody to experiment with the minimum required thing to use the createjs tag plugin for them and see if we can inline such tags with the main entity in some way or not.

Hi,

just a quick comment: travis says the tests fail for this because some doctrine stuff can't be found:

PHP Fatal error:  Class 'Doctrine\Common\Annotations\AnnotationRegistry' not found in /home/travis/builds/flack/createphp/tests/Test/Midgard/CreatePHP/Extension/Twig/CreatephpExtensionTest.php on line 40

so it seems composer.json or something has to be updated. I wonder if composer supports conditional dependencies, but well, for the moment we can make do with the dev switch

[dbu]

yes, would be a typical case for --dev. the optional stuff is handled with suggest and up to the user whether he wants to include suggestions in his main composer.json.

i will investigate this when i find time again to work on it, not sure how soon that can happen.

[dbu]

what is done here is fixed in #46 too. the only issue are the nontype collections of tags where i still miss an example of how the tag plugin of create.js works

@dbu: I'm not really sure I understand your last comment. Do you mean to say that this is superseded by #46? If so, can I close this PR? Travis shows 3 errors and one failure for it right now, but different ones than when I made my last comment, so there seems to be some progress :-)

[dbu]

i will update this branch once #46 has been merged and see what is still relevant.
