Unable to exclude elements with "textmate" scope selectors in custom themes

[madeso]

Issue Type: Bug

Hello!
I haven't found great documentation for the tokenColors.scope property. The only syntax documentation about scope selectors I've been able to find is the textmate "specification", so it's possible this is just a documentation/user issue and not a bug:

I'd like to highlight function names entity.name.function and exclude function calls. Most languages I tested (c, c++, js, ts) doesn't seem to differ between theese (python does) but seems to add a additional scope called meta.function-call to distinguish.

Sample code (from doom) that I'm testing highlight with:

static void derror(char* msg)
{
    fprintf(stderr, "\nwadread error: %s\n", msg);
    exit(-1);
}

And just like the textmate documentation (13.3 Excluding Elements) says I try to exclude function calls from functions but the whole exclude pattern seems to be picked up as a identifier.

{
	"tokenColors": [
		{
			"name": "Global definitions",
			"scope":
			[
				"entity.name.function - meta.function-call"
				, "entity.name.scope-resolution.function.definition"
				, "entity.global"
			],
			"settings": {
				"foreground": "#6c71c4"
			}
		}
	]
}

So I guess this is a bug, if not:

• where can I find better documentation more suitable for vs code and
• how should I exclude one, or more, scopes?

vscode-textmate (the library we use to tokenize and theme) does not support the minus operator in theming rules.
