Weird errors while trying to properly configure the ls

[Q-Master]

I'm trying to configure nim ls in vs code. Seems that I'm doing something wrong because I'm constantly getting anything except working code highlighting.

The config I'm trying now is

    "nim.projectMapping": [
        {
            "projectFile": "gui-engine.nimble",
            "fileRegex": "src/.*\\.nim"
        }
    ]

This is the library code, so it has no one file which imports everything and exports all the functionality.

Most files are not showing any symbols and showing some weird errors like this:

The existing documentation is not describing how should library projects be configured.

[jmgomez]

You dont need to setup your project entry to the nimble file. nimble lsp support is limited in the nimble file itself. If you are using nimble, you shouldnt need to setup anything in the extension, as the lsp uses nimble dump to figure the project root

[Q-Master]

The documentation for nim lsp is not describing on how should one properly set up the configuration while writing a library code, not single binary. The're is usually no single entrance point for all the library code, thus pointing the lsp to some file will definitely not show any symbols from files not imported there. I've already checked this.
