@lmcbout I believe it's the same errors you noticed when testing the go vscode extension?

[akosyakov]

I'm testing go extension :) Do you have an issue already? Is it a dup?

No no :) I know @lmcbout was trying the go extension to see how well it worked.
It'd be nice to know your findings as well while you test.

@tolusha you don't have these errors ?

[tolusha]

I didn't have any errors.
I've just put GO extension [1] in the plugins folder and checked.

Hi,
I tried to install the same vscode go extension. It seems to work. However, there is no textmate. To add the coloring, I created a local copy for

• GoContribution: in packages/textmate-grammars/src
• go.tmLanguage.json: in packages/textmate-grammars/data // Copied it from vscode
  -textmate-grammars-frontend-module.ts : add handling for the GoContribution
  then I reloaded the application and I have the textmate available for the "*.go" file.
  I tried the Go:run.. and the debug. Both seems to work well, i was able to add break point in the file as well.
  My changes might not be necessary when Theia supports all vs-code API (Issue #4446 and issue #4448)

From the go extension documentation there is not mention of providing the textmate-grammar (coloring) so I don't believe the extension attempts to provide it. In addition, I can see coloring in vscode for go files without the extension even installed.

[akosyakov]

I've installed built-in go extension to enable coloring, you can get it from https://github.com/theia-ide/vscode-builtin-extensions We can move textmate grammars from Theia go extension to textmate-grammars extension as well. Please file an issue and PRs are welcomed as usual.

[benoitf]

FYI about grammar, (and the move from theia go extension to textmate-grammars)I it was part of https://github.com/theia-ide/theia/pull/4070
but due to being blocked by https://dev.eclipse.org/ipzilla/show_bug.cgi?id=18775 it was being opt-out of the PR
it is postponed until CQ is accepted

[akosyakov]

I can reproduce it with https://marketplace.visualstudio.com/items?itemName=hoovercj.vscode-power-mode wanted to have some fun :)
