Fix embedding in new YAML grammar

[RedCMD]

VSCode is adopting a new YAML grammar
microsoft/vscode#224978

Injecting into nested block maps doesn't work fully anymore
this is because the new grammar captures the prefixing whitespace, disallowing this injection to capture the newline ^

Workaround is to change ^ to (^|\\G)

I haven't been able to replicate your nested test example. Is there anything specific that needs to be done? Here's my version of VS Code

Version: 1.92.2

VSCode temporarily reverted it in 1.92.1 microsoft/vscode#224862 (comment)
1.92.0 had the new grammar
or you can install the grammar directly https://marketplace.visualstudio.com/items?itemName=RedCMD.yaml-syntax

Hmm strange, even after installing your extension directly I haven't been able to reproduce it. Is there any difference between the grammar released by VS Code and your extension? Also I've noticed we seem to lose bracket pair colorization. Do you know why this might be? If this is the new grammar could you look to add this back at some point? It's nice to have someone looking to actively maintain the YAML grammar, so thanks.

Also I've noticed we seem to lose bracket pair colorization

That is caused by 3 different issues

• I had removed parenthesis (, ) from bracket pairs in YAML. Because YAML has no () brackets.
• I had disabled all bracket matching within meta.scalar.yaml.
  I've fixed it now, {} and [] will match highlight now. (pre-release version)
• js is not a language; in your package.json. Fixing this will readd ()

Could you send a screenshot of the code with editor.action.inspectTMScopes enabled please

nested:
  test: | #js
    console.log("hello world")

Thanks, I've fixed this on my end in #29. I have downloaded the old version of VS code (1.92.0) and again can't reproduce.

I'm interesting in you're following statement which sounds like it could potentially fix #13

this is because the new grammar captures the prefixing whitespace

do you have another YAML extension installed? RedHats?

my extension does partially fix it

but only if there is sufficient nesting for the current indentation

[harrydowning]

do you have another YAML extension installed? RedHats?

Ah yeah, that could be it

[RedCMD]

early September if they decide to re-add it

how does it break with the old grammar?

sorry didn't mean to close it

[harrydowning]

early September if they decide to read it

how does it break the old grammar

Sorry, I just tested this and it doesn't. Merged now
