Starts the Roux LSP server over stdio.
The server reads language configuration from the :roux key in
Mix.Project.config/0 and registers all languages with a fresh
database before accepting LSP protocol messages.
Needs the optional :gen_lsp dependency: add {:gen_lsp, "~> 0.11.3"}
to the project's deps.
Usage
mix roux.lspConfiguration
# In mix.exs project/0:
def project do
[
...,
roux: [languages: [MyLang]]
]
end
