sbt server talks Language Server Protocol using Unix domain sockets. sssio (sbt server standard input and output) automatically discovers sbt server's opened socket and converts it to standard input and output which most of the editors expect.

If you are using neovim with autozimu/LanguageClient-neovim then add the following to your ~/.config/nvim/init.vim:

let g:LanguageClient_serverCommands = {
    \ 'scala': ['coursier', 'launch', 'lt.dvim.sssio:sssio_2.12:0.0.1'],
    \ }

This uses coursier to fetch the artifacts. If you are running Archlinux you can install coursier from AUR.

To write all of the communication between sbt and LSP client to a file, add the following parameter:

-Dsssio.logfile=target/sssio.log
