Syntax Highlighting doesn't update properly

[DianaNites]

Syntax Highlighting in the current tab fails to update properly with changes.

A workaround is to switch to another tab and then back, which I guess makes it recompute highlighting, but thats not very practical when writing code.

Examples:

Normal:

After typing a comment:

Even weirder, some parts of the line actually have updated, the =, :, ;, (, and ) characters are green. But / is blue?

Using VSCode 1.37.1 and rust-analyzer master, commit c7d37e4

Not using rust-analyzer.rainbowHighlightingOn

That was a really stupid bug, sorry! Will be fixed by #1712

To clarify, you need to update vscode plugin to get the fix, with

cargo install-ra —client-code

Works great now, thanks!

[shekohex]

works fine 👍 , thank you!

I've done cargo install-ra --client-code and still suffer from this:

Very confusing highlight:

Steps to reproduce: open up a properly-highlighted code file, select a bunch of code, drag them elsewhere (which messes everything up 🤣) and undo. You'll see highlighting like this.

This has regressed for me too, including for newly opened projects. Have to switch tabs to get highlighting at all when first opening a project.

Unable to test the new commit right now, but says the fix is windows only? I use Linux and experience this issue, though.
