Outstanding Grammar Issues #3924

vmg · 2017-11-30T11:07:35Z

The following is a detailed list of all the outstanding issues in the grammars that GitHub.com uses for syntax highlighting the code in our website.

These issues are detected by our grammars compiler (#3915) and are probably causing minor rendering bugs in the website.

Help is very much welcome! If you're seeing bugs or rendering issues in your source code in GitHub, please start by taking a look at this list to make sure we're not detecting any issues in your language's grammar.

Feel free to ask any questions about any given issue and what would be the appropriate way to fix it. I'll keep the issue up-to-date as I work through grammar fixes myself.

Thanks for the useful and actionable list @vmg. One question...

repository vendor/grammars/language-babel (from https://github.com/gandm/language-babel) (14 errors)

Is this the actual upstream grammar as it stands now or the old pinned copy we're shipping with Linguist at the moment?

I'm assuming the latter, but thought I'd check to be sure.

vmg · 2017-11-30T14:12:57Z

I'm assuming the latter, but thought I'd check to be sure.

Correct! I fucked up my submodules. Sorry about that, I'll update the list with the proper URL.

Alhadis · 2017-12-05T00:19:15Z

Hey, sorry about the (really) slow response. My MacBook died last week, which means I've been painfully limited in what I'm able to do on GitHub (I'm using my work's computer for the time being, when time permits).

The issues reported by my grammars are easily fixed; but the LilyPond grammar should be fixed with a PR to the upstream repository. Basically, the scope.AtLilyPond should be replaced with just scope.lilypond so it's consistent with other LilyPond grammars (and I can therefore replace the offending rule in text.roff with a single inclusion: {include: "source.lilypond"}.

Alhadis · 2018-01-01T05:42:30Z

What's the maximum token length permitted by the new compiler? I was about to start fixing the issues with Emacs Lisp's grammar, but realised I don't have the actual limit to go by.

Admittedly, I'm not really fond about the size limit, because the "fix" here is to simply break the pattern down into multiple rules that're bunched together under the same name. It feels terribly hacky, and the fact that the rules in question were compiled from an external source means that updating the list in future might be made more complicated...

vmg · 2018-01-08T09:48:57Z

@Alhadis: Sorry, you caught me on Holidays. The maximum size is enforced by PCRE, not by our parser, and it's 64kb for a single regexp. I'm aware it's a bummer, but it's the way PCRE was designed.

Alhadis · 2018-01-08T11:29:36Z

That's understandable. How is whitespace treated inside expressions which use "expanded" notation...?

m/
	abc
	(?:
		xyz
	)
	(?=\w+)
/x;

Because there are two different ways to represent that in CSON. One is with an ordinary quoted-string, which includes embedded newlines as part of the pattern...

pattern: "(?x)
	abc
	(?:
		xyz
	)
	(?=\\w+)
"

... and the other is to use triple-quoted strings ("heredocs"):

pattern: """(?x)
	abc
	(?:
		xyz
	)
	(?=\\w+)
"""

The latter will strip as much indentation as it can, leaving some (but not all) horizontal whitespace after the CSON-to-JSON conversion:

(?x)
	abc
	(?:
	        xyz
	)
	(?=\\w+)

Now this won't make any difference to the regex engine, but it will to my subdivision efforts... 😀

vmg · 2018-01-08T17:59:58Z

@Alhadis I'm honestly not sure of how exactly does PCRE implement this -- you should be able to test it out by simply downloading libpcre and trying to compile in the regexps. Our parser has no custom behavior here.

lildude · 2018-01-29T14:00:37Z

I've updated the sublime-mask output in the OP as the latest grammar compiler now prefer the "compiled" .tmLanguage file over the YAML file and sublime-mask has only updated the YAML file. I have pinged the author in tenbits/sublime-mask#1 asking them to update the mask.tmLanguage file too.

tmillr · 2022-09-19T05:19:55Z

I'm not sure where to post this so I'm just gonna post it here. I came across a TypeScript rendering/syntax highlighting issue the other day here on GitHub. I sent in a support ticket and they redirected me to this repo.

The issue can be viewed here. Thanks

lildude · 2022-09-19T10:27:03Z

@tmillr grammar problems should be reported with the upstream maintainers. In the case of TypeScript it is this repo. As this is a tree-sitter grammar, Linguist has no control over the updates so it's possible this issue has been fixed but not yet pulled into GitHub.

DaelonSuzuka · 2022-11-29T23:22:41Z

@lildude The Godot Engine grammars should have been fixed in godotengine/godot-vscode-plugin#416.

I attempted to validate the fixes using the grammar compiler instructions you gave us, but I don't know how to actually run linguist to make 100% sure that they're working now.

lildude · 2022-11-30T10:49:49Z

I don't know how to actually run linguist to make 100% sure that they're working now.

Running Linguist wouldn't help you as it doesn't actually do the highlighting. This is done by an internal service so you can only go based on what the validator says, or not.

dragoncoder047 · 2023-01-31T16:35:07Z

The Python grammar referenced by this repo (MagicStack/MagicPython@7d0f2b2) includes support for the new Python match/case keywords but I'm not seeing them highlighted (see here). Is this just caused by the latest Linguist not being deployed to the Github backend servers (why would it take three months to do that??), or is there some other bug?

Alhadis · 2023-01-31T16:38:50Z

@dragoncoder047 Unfortunately, GitHub uses a specialised Tree-Sitter parser for Python; the MagicPython grammar is only used to highlight code-blocks in comments.

@dragoncoder047 Unfortunately, GitHub uses a specialised Tree-Sitter parser for Python; the MagicPython grammar is only used to highlight code-blocks in comments.

I guess it's a bug in the grammar then. It's already been reported (tree-sitter/tree-sitter-python#141) so I won't bother re-filing it.

Hello hello,

I don't know how this issue works but we supposedly eliminated the \p problems from the Raku repository. I'm curious about the result...

Not gonna lie, I'm perfectly clueless how Digit could remain when I even noted that it can/should be replaced to Nd... anyway, soon to be addressed.
