ability to manipulate configuration variables

[amir-arad]

I've encountered a similar need to #73888 . I pass ${workspaceFolder} as a parameter to some (ms-vscode.cmake-tools plugin) and it parses the string, producing the following error:

[cmake]   Syntax error in cmake code when parsing string
[cmake] 
[cmake]     c:\workspace\EmptyEpsilon/../SeriousProton/src/soundManager.cpp

So for my specific case I need a version of workspaceFolder with either backward slashes, or double forward slashes. But in general I think a way to manipulate the value (replace?) can come in handy.

Where are you passing ${workspaceFolder} as a parameter?
Please be aware that in general variables like ${workspaceFolder} can only be used in launch.json and tasks.json, but non in settings.json.

as part of a parameter in settings.json. This is a workspace configuration I wrote, which several people use, and for some reason no longer works.

could you please show me a reference to what configuration should go where?so that I can re-write my configuration, or at least offer a heads up to the vscode-cmake-tools people

The variables available in launch.json and tasks.json are specified here: https://code.visualstudio.com/docs/editor/variables-reference

In that document is an FAQ entry for settings.json:
https://code.visualstudio.com/docs/editor/variables-reference#_is-variable-substitution-supported-in-user-and-workspace-settings

@bpasero do we have a complete list of variables that can be used in settings.json?

[bpasero]

Forwarding to @roblourens @sandy081 do we have a complete list of variables that can be used in settings.json?

Maybe they should be showing up in IntelliSense?

[roblourens]

They do show up in intellisense, but they are only supported as special cases for specific settings like window.title.

[sandy081]

We do not support any variables in settings. Its up to each setting to define their own variable and resolve them.

See - #2809
