Hi, thanks for these helping regexes.

Some suggestions:

• Maybe add some explanation for short, medium, etc., twig syntax. How does short, medium, etc., syntax look like?
  What are the new conventions?

• Add possibly a hint that all regexes cover different syntaxes.

• Transform .txt file to .md file and use markdown features

• Some tags and functions in twig are currently not supported here. (only form_theme was relevant for us, hint would be nice)

  • form_theme
  • source
  • embed
  • render-esi

• Warning about template_from_string

• Ternary syntax is not supported. E.g.: {% extends editmode ? 'foo.html.twig' : 'bar.html.twig' %}

• Shorthand syntax with two colons is not supported. E.g.: {% include '::test/foo.html.twig' %}

  • Or without further path elements {% include '::foo.html.twig' %}

This doesn't solve cases like <?= $this->input("headline", ['placeholder' => 'Headline']); ?>, right?

Are there any expressions available for converting PHP syntax to TWIG syntax?

Hello @kovinet!

If you have stumbled across this collection during the update of Pimcore 6.9 to Pimcore X keep in mind:

• If I remember correctly, this will only find some changes in the Twig syntax and their namespace resolution (especially for render and include functionalities).
  • e.g.: {% extends ':Layout:default.html.twig' %} to {% extends 'Layout/default.html.twig' %}
• At this point in the update process we have already migrated all/most of our PHP templates. This will probably be a manual process but you can help yourself by searching for specific keywords in the project (<?=).
• The major problem during this migration process are not the syntax changes but that you can have a lot of logic in the PHP templates that you cannot (and shouldn't) have in Twig. This will be the most time consuming change, in my opinion.

TLDR; no it does not migrate PHP templates to twig templates but updates the Twig namespace syntax.

Good luck with the update!
