Re: [tlaplus] TLA+ tree-sitter grammar updates

[Andrew Helwer <andrew.helwer@xxxxxxxxx>]

Yeah Markus pointed this out to me a couple months back. Originally the plan was to keep using the regex highlighter for snippets for this reason, but I guess that was overlooked when this was enabled. I think what I will do is modify the grammar to parse TLA+ snippets that aren’t contained within module start/end markers. This will mean the grammar accepts invalid TLA+ but it already does that in a few cases (tree-sitter grammars are permissive by design) so no big deal. Then I will email github contacts to update it (this feature is still not publicly available unless you know somebody).

Yes, snippets broke when the new grammar rolled out. I reported [1] a bug, but nothing has happened.

It seems that now TLA+ snippets in Markdown aren't highlighted unless they are contained within a full module e.g see here. I could be mistaken, but I seem to recall that in past these snippet blocks would highlight TLA+ expressions even if they weren't enclosed within a full module definition.
