Clio programming language support

Describe your feature request
Add highlighting, a language server, and a template for Clio, a new programming language that compiles to JavaScript. A VSCode highlighting extension already exists, as well as the language server.

What problem(s) would this feature solve?
It would allow easier usage of Clio.

Explain what you were trying to do when you came across the problem leading to this feature request
I was trying to write a backend server in Clio.


@PoolloverNathan Replit uses Nix, so someone has to make a Clio Nix package (which doesn’t exist). And sadly, Replit is not making templates anymore.
And I highly doubt Replit will even bother with making a language server and add highlighting for an unknow language.

To summarize, you can’t use Clio in Replit.
So just go back to VSCode.


I made a basic clio template here, but there is no syntax highlighting since the language is not supported by the Replit IDE.
