Vscode-r: [feature-request] Richer syntax definition

[Shians]

Could I suggest adding richer syntax definitions and highlighting? Something like https://github.com/randy3k/R-Extended?

@Shians Great! I'll hope your help. Thank you.
I think same developers https://github.com/randy3k/R-Box/tree/master/syntax product is better. Because it is MIT license and updating still.

@Shians In new version, it has been expanded from Rbox.
But it's immature and R markdown and R documentation are yet.

I can't quite get my head around how these tmLanguages are written, it seems to be very hard to read or write by hand. Some resources suggest they are compiled from a JSON file but nobody provides the source JSONs. Upon comparison with the highlighting in Sublime I see that the main difference is for function calls to be highlighted.

Since base VS Code has an R syntax I wonder if it's worthwhile figuring out the syntax definition for a function call then pulling it into the main project.

OK, now I'm making script that convert sublime-syntax to JSON, and submited PR to VS Code base.

Along these lines, I'd also very much appreciate if code symbols could be included in the extension as well; this would enable IntelliSense auto completion and browsing by symbol which is essential for larger projects. Here are the docs for how this should be specified. Thanks again for the great work.

@schelhorn Looks good. I'll try it, thank you!

Sorry, my reply is late.
@Shians In Microsoft/vscode@012d7da, this repository will be referenced original VS Code repository Microsoft/vscode#28982, and VS Code user can use better R syntax without installing this extension.
So, this repository will update continually and take latest syntax.

@schelhorn, We will create IntelliSence autocompletion by https://github.com/REditorSupport/languageserver #24.
