I'm writing a vscode extension and I'd like to register languages dynamically, based on user configuration. The extension would then instantiate LSP clients to talk to servers derived from user configuration as well.
This would allow for people writing custom and toy languages to get an extension "for free" and experiment with editor features without necessarily having to implement and publish the vscode part of it.
I've dug a bit in the vscode sources, and found an interface that seem like it could help : "ILanguageService", but I'm unsure as to whether this is something that's accessible from the extension API.
Any idea how I could go at it ? Is it even possible ?
