Is ra-multiplexer suitable to multiplex any language server?

[andrewhamon]

The section "Other LSP servers" seems to indicate ra-multiplexer supports at least clangd.

Is any generic language server supported? Any caveats to be aware of?

[pr2502]

LSP is a standard protocol and ra-multiplex supports a significant portion of it, meaning other LSP servers should just work. Caveat is that I haven't tested anything beyond rust-analyzer and clangd and only use it myself for rust-analyzer since no other language server I regularly use is heavy enough to warrant it. But you're welcome report issues specific to LSP servers other than rust-analyzer if you run into any.
