Support "variables scoped per workspace folder" (e.g. ${workspaceFolder:Project1}) in config values

[braindevices]

Please describe the problem.
For hints on what information is helpful, see: https://clangd.llvm.org/troubleshooting.html

If you can, provide a minimal chunk of code that shows the problem (either inline, or attach it if larger).

settings:

"clangd.trace": "~/clangd.log",
"clangd.path": "${workspaceFolder:cpp-project}/clangd.sh"

It will report cannot find '/path/to/workspace/${workspaceFolder:cpp-project}/clangd.sh' cannot be found.
Log file is also missing.

${workspaceFolder} should work, its substitution is implemented here.

~ is not supported but looking further up in the same function, ${userHome} should work as an alternative.

Hmm, but at least it doesn't expand the workspacefolder in my example when I put it in clangd.path

I can't reproduce this, it seems to be expanded fine for me.

Can you provide some more details?

• vscode-clangd version
• vscode version
• path to the file containing the "clangd.path" setting
• contents of the file contianing the "clangd.path" setting
• contents of clangd.sh (assuming it's a script)

Sorry, since I modify the settings too many times for testing, I actually mixed up things.
${workspaceFolder} works fine, but the Variables scoped per workspace folder ${workspaceFolder:<one of the workspace root folder name>} does not work.

I have to use ${workspaceFolder:cpp-project} to identify the path, since clangd only starts in the root1.

{
	"folders": [
		{
			"name": "non-cpp-project",
			"path": "../root1"
		},
		{
			"name": "cpp-project",
			"path": "../root2"
		}
	],
	"settings": {
		"python.defaultInterpreterPath": "${workspaceFolder}/venv/bin/python",
		"cmake.cmakePath": "${workspaceFolder}/cmake.sh",
		"cmake.configureArgs": [
			"--fresh"
		],
		"cmake.useCMakePresets": "always",
		"clangd.arguments": [
			"--log=verbose",
			"--suggest-missing-includes",
			"--pretty"
		]
	}
}

Thanks. I revised the issue title to be about this latter case.
