Re: New release of LSP server; LSP clients for Emacs and VSCodium available

[Aleix Conchillo Flaqué]

Fantastic, thank you! I just packaged both scheme-json-rpc (as
guile-json-rpc) and scheme-lsp-server (as guile-lsp-server) for
homebrew-guile (https://github.com/aconchillo/homebrew-guile). Tests and
executable seem to work (or not fail) but I haven't really tried it yet.
The plan is to make it easy for everyone on macOS to hack on Guile using
either Emacs or VSCode.
