Please fill the following fields with a star (*) and provide as much related information as possible.

Pre-checks*

Please change the following [ ] to [x] for confirmation.

• [x] The issue has not been reported in this repository.
• [x] The issue remains after disabling all other extensions and restarting Visual Studio Code.
• [x] The FAQ cannot address the issue.
• [x] The issue is not related to compiling a document, or the document can be successfully compiled in the OS terminal but not in Visual Studio Code with this extension. (it actually just compiles fine and I get a PDF, chktex is just going frenzy)

Environment*

Please write exact version numbers instead of descriptors such as latest.

• Operating System: MacOS 14.2.1
• Visual Studio Code Version: 1.87.2
• LaTeX Workshop Version: 9.19.1
• TeX Distribution Version: TeXLive2024

The Issue*

I updated my TeXLive to 2024 today and since then on every save chktex errors with

chktex: WARNING -- Compilation of regular expression \[(?![^\]\[{}]*{(?![^\]\[{}]*}))[^\]]*\[ failed with error repetition-operator operand invalid.

which I am not sure where it is from, but I thought I would just deactivate it for a while. So I Unchecked

• Latex-workshop > Listing > Chktex > Convert Output > Column: Enabled
• Latex-workshop > Listing > Chktex: Enabled

But the error still appears on every save.

Reproduction Steps

1. Update to TeXLIve 2024
2. open a LaTeX file in VS COde
3. click save

Expected Behavior

chktex would not run if not enabled

I have made a test and I confirm that when latex-workshop.linting.chktex.enabled is unchecked, chktex is not called. When chktex is called, you should find in your logs something like

[17:14:02.555][Linter] ChkTeX lints root %WS1%/empty.tex .
[17:14:02.556][Linter][ChkTeX] Linter for ChkTeX command The command is chktex:["-wall","-e16","-n1","-n6","-n12","-n19","-n21","-n22","-n24","-n25","-n30","-n37","-n44","-n46","-q","-n45","-n36","-n2","-n3","-l","%WS1%/.chktexrc","-f%f:%l:%c:%d:%k:%n:%m\n","%WS1%/empty.tex"].

I am pretty sure the warning comes from your configuration of chktex. Do you have a .chktexrc file somewhere?

[kellertuer]

Hm. No nothing. and It also only started showing up (but something like every other second!) since the update. I never set up anything besides enabling it in the extension. so there is not .chktexrcfile or such.

[jlelong]

I have just installed TexLive 2024 and I confirm that the default chktex configuration has an issue. See https://savannah.nongnu.org/bugs/index.php?65033 No new version has been released so far. The latest release seems to go back to 2022.

Yet, unchecking latex-workshop.linting.chktex.enabled does disable chktex.

[kellertuer]

Thanks for the follow up. For me it did not disable the call it seems, I really tried several times. But I can check back; my impression was that the chutex was still called, maybe not for this one document open but for some other reasons and still caused the error.

[kellertuer]

Ah, I just saw I also have the LaTeX extension running (disabled that, not sure why I had that) – that still called chktex. So deactivating works and the error is gone, but it would of course be nice to have linting back at some time ;)

[jlelong]

Even with the current warning message of chktex about the invalid regex, LaTeX-Workshop is able to parse its output and displays the correct linting messagesat least on my configuration. Can you try again now that you have disabled the LaTeX extension ?

[kellertuer]

Ah nice, indeed, that works again. Now it would just be nice to exclude a few (46 – use ( ) instead if $ $ for example). But that is maybe something for an own configfile. Will check

Nice, thanks, will do :)
