Notice

Since 1.43.0 VSCode enabled a new feature called Semantic Highlighting, this extension supports it.

By default, only the built-in themes has semantic highlighting enabled, so if you are using a 3rd party theme that doesn't support the semantic coloring yet, you have to add these lines to your settings.json file to have the feature enabled.

"editor.tokenColorCustomizations": {
	"[name of the theme]": {
		"semanticHighlighting": true
	}
}

For extra information see https://github.com/microsoft/vscode/wiki/Semantic-Highlighting-Overview.

Here is the comparison with and without semantic highlighting.

On left enabled, on right disabled
