Pattern generation fails with an error

[davidcmoulton]

Generating the patterns using this starter kit gives the following error (file paths have been sanitised)):

Fatal error: Uncaught Error: Call to undefined method __TwigTemplate_cb87d917ee046806b780332adb3b678cc4ebc7d51303b5fbaa0bca108638e7a0::getinput() in [...]/pattern-library/vendor/twig/twig/lib/Twig/Environment.php(467) : eval()'d code:50

Steps to reproduce:

Prerequisite: install PHP Pattern Lab Twig and verify it works with the base starter kit

1. install Pattern Lab edition-php-twig-standard via recommended composer command (composer create-project pattern-lab/edition-twig-standard pattern-library && cd $_)
2. during the installation process choose to install starterkit-twig-base. (Note we're not choosing starterkit-twig-demo because of the advice not to install this via Composer.)
3. once installation has finished, run php core/console --generate. This runs fine.

Demonstrate the error

1. install starterkit-twig-demo (don't use Composer): php core/console --starterkit --install pattern-lab/starterkit-twig-demo.
2. once installation has finished, run php core/console --generate. This causes the error.

This looks like a bug to me, but I realise I might be missing something.

Same issue here. @davidcmoulton did you find a workaround?

[ladyhunterbear]

Workaround:

1. Delete patterns/00-atoms/05-forms/00-text-fields.twig - there appears to be an issue with the import.
2. Edit patterns/03-templates/03-article-2col.twig, first line should read
   {% extends "@templates/00-layouts/page-2col.twig" %} not {% extends "@templates/page-2col.twig" %}

Confirming this works for me. Thanks @ladyhunterbear.

Based on what @ladyhunterbear said I'd like to add my findings:

1. you don't have to delete that file (00-text-fields.twig)! Just have a closer look into the config.yml and change the line twigMacroExt: macro.twig to twigMacroExt: macro.php

This way php should be able to render the referenced macros.

@jirmueller Unfortunately changing twigMacroExt to macro.php doesn't work for me. I will keep on searching and updating the thread with my fiends. Thank you!
