Syntax error after update to ST4

#1

I have just updated to ST4 and I got a new error when it starts:

error: Error loading syntax file "Packages/....sublime-syntax": Apparent recursion within a with_prototype action: 25000 context sanity limit hit

All I have with “with_prototype” is in this fashion, one per language:

- match: ^__python$
  push: Packages/Python/Python.sublime-syntax
  with_prototype:
    - match: (^__$)    # OR (?=^__$)
      pop: true

- match: ^__html$
  push: Packages/HTML/HTML.sublime-syntax
  with_prototype:
    - match: (^__$)
      pop: true

…

This tries to apply a specific syntax to the text between two strings. Is there anything wrong in the syntax?

HTML includes CSS and JS which got a bit more complex. So it is very likely for with_prototype to cause that issue.

Replacing those lines by

- match: ^__python$
  embed: Packages/Python/Python.sublime-syntax
  escape: (^__$)    # OR (?=^__$)

- match: ^__html$
  embed: Packages/HTML/HTML.sublime-syntax
  escape: (^__$)

should do the trick.

It works indeed! No more errors. So I suppose the issue was caused by HTML interdependencies, and for some reason the error check was not enabled in ST3. Thanks

The error checking mechanism hasn’t changed, but syntaxes got more complex over time so it’s more likely to hit the limits with those legacy constructs.
