Error: Illegal argument: character must be non-negative

[renpytom]

I've been getting the attached error in language-renpy v , in vs code 1.79.2. When it happens, it interrupts my typing, with a second-long pause. I'm seeing this in the extension host output - not sure if there's something more directly part of vs code. It seems to happen when editing strings in the renpy/common directory.

I'm also seeing a lot of "The token tree is not covering the entire match range" errors in the developer tools console.

To repeat, go to renpy/common/00director.rpy, line 1372, and add a space after int(v), at the end of the line.

Hi tom, it seems you are still using v2.2.1.

at t.getSignatureHelp (/home/tom/.vscode/extensions/luquedaniel.languague-renpy-2.2.1/dist/extension.js:2:73557)

In 2.2.1 we had a bug in the tokenizer that would cause an infinite loop or major slowdown in some cases. v2.2.2 stable was just released with all the bug fixes from the pre-release version so it should be okay in the latest build.

I did try to reproduce it, but I was unable to do so. Let me know if you are still experiencing issues in the latest build and I'll be happy to take another look :)

I actually did manage to find the error you got. #352 should fix that, though it seems the error is unrelated to the interrupted typing
