[coffeescript] syntax highlighting breaks on indented comment blocks

[pzuraq]

• VSCode Version: 1.7.0
• OS Version: 10.11.6

Steps to Reproduce:

1. Add comment block (three hashtags in a row)
2. Indent comment block

[pzuraq]

This appears to be caused by the lookbehind used in the regular expression marking the beginning of a comment block here. For some reason, this expression matches all characters except for empty spaces.

A temporary fix on my machine is to change the expression from (?<!#)###(?!#) to ^[^#]*###(?!#), though this would possibly break for multiple block comments on a single line.

Per @aeschli, VSC's CoffeeScript grammar is from https://github.com/textmate/coffee-script.tmbundle. There is a corresponding issue in that repo.

Any word on this and #15008? I've been fixing it manually but whenever VSCode updates it wipes that out. Really tedious for me, would love to fix it if I can help.

They already have a PR in for the fix ... textmate/coffee-script.tmbundle#11

[pzuraq]

@drKnoxy seems to be dead in the water, and there isn't a fix for #15008. Are we sure that the maintainers of that package are active?

[drKnoxy]

Probably inactive, I hear everyone is switching from textmate to vscode (har har har)

[aeschli]

Fixed by switching to the atom/language-coffee-script grammar.
