[Question] Integration with Rustaceanvim

[pi314ever]

How do I integrate this with rustaceanvim? It has many more features that I would love to have that builds on top of rust analyzer, but I cannot figure out an interface between ra-multiplex and rustaceanvim.

I have tried ln -s ra-multiplex rust-analyzer to see if it can drop-in replace at least the client side, but it doesn't work due to differing APIs. Specifically, it complained that it could not use --log-file flag.

Any help on this would be greatly appreciated!

Having had a look at the rustaceanvim help (:help rustaceanvim.config I believe) there's a rustaceanvim configuration object which contains a settings object which can override cmd. It doesn't look like this can take the result of vim.lsp.rpc.connect() but you can try that first (as per the neovim example). If it doesn't work, set it to the path of "ra-multiplex".

While undocumented, rustaceanvim appears to also look for an init_options in the same place (as per https://github.com/mrcjkb/rustaceanvim/blob/29f42cc149f915d771c550b6dfe7c788d856cf04/lua/rustaceanvim/lsp/init.lua#L112 ).

Once you set those two things, it hopefully should work.
