Hi @justb3a,

I just noticed when I upgraded to the latest version of TemplateEngineTwig that I'm now getting an error message.  I think the TwigExtensions vendor library might possibly need to be upgraded in this module as well.

On https://github.com/twigphp/Twig-extensions it say's it is up to 1.5.1.  This module includes 1.3.  TemplateEngineTwig upgraded Twig from 1.24.2 to 1.35

I just manually tried to "composer update" in the TwigExtensions module directory, but now I get a different error:


Do you have any ideas as to why I'm getting these errors?

This is not working for me! I'm using the following:

  • Template Engine Factory 1.1.3
  • Template Engine Twig 1.1.0

I get this error:

User Error Exception: An exception has been thrown during the compilation of a template ("Object of class Twig_Source could not be converted to string") in {}. (in C:\MAMP\htdocs\twig\site\assets\cache\FileCompiler\site\modules\TemplateEngineTwig\TemplateEngineTwig.module line 94)

Since I'm new to PW, I'm afraid I can't be much help!

@V7dev - Twig Extensions module seems to work fine with Template Engine Factory 1.1.3 and Template Engine Twig 1.0.4

Hopefully @justb3a can take a look some time soon to see why it's not working with Template Engine Twig 1.1.0?

I'm still trying to figure it out, but I'm not making much progress.  :(

@gmclelland - That's odd, I just installed a fresh copy of TE Factory and TE Twig with the latest Twig Extensions and I get an internal server error; I disable the Twig Extensions, the site works fine - not sure how I could have messed up such a simple procedure, but I wouldn't put it past me! :)

@justb3a I was able to fix this module to work with the latest version of TemplateEngineTwig by modifying TwigExtensions/composer.json to:

    "require": {
        "twig/extensions": "~1.5",
        "twig/twig": "~1.35"

and then run composer update.

Twig also gets installed when composer install is ran because it is a dependency of Twig Extensions Library.  So anytime the TemplateEngineTwig module updates it's version of Twig, this module will also need it's version to match.

Here's the pull request. https://github.com/justb3a/processwire-twigextensions/pull/11

I think we also should remove the debug extension.  That's included in the TemplateEngineTwig module now.  See https://github.com/wanze/TemplateEngineTwig/commit/776d3d8b3cf2fd04ea584d92fdc33e214468996b#diff-174a5e0bac30f021aa66bb8899550f87R55

I'll try to create a pull request for this fix as well.

Hope that helps!
