        <pre>I've got clangd hooked up in VSCode and really like it. As part of my work I
also need to write MATLAB code for which I'm using the vscode-matlab extension
and have the extension .m bound to the language "matlab" in VSCode:

  "files.associations": {"*.m": "matlab"}

However when I open a .m file in VSCode with clangd running, it validates the
file, likely as Objective-C, causing a bunch of errors to show up.

Can clangd indexing be based off of the language rather than the file
extension?

<a href="https://github.com/microsoft/vscode-extension-samples/blob/master/lsp-sample/package.json">https://github.com/microsoft/vscode-extension-samples/blob/master/lsp-sample/package.json</a>

shows binding with a language as well as their client:

Using this mechanism allows users to perform the extension to language mapping
on their own.</pre>
