DEPRECATED - lsp-scala

lsp-scala is now part of lsp-mode as lsp-metals. Please do not use this package.

Scala support for lsp-mode, mainly focus on metals.

Installation

Installation instructions with metals are available here: https://scalameta.org/metals/docs/editors/emacs.html

Other Scala language servers

Other Scala language servers should work in theory. The easiest way, if your server launches from the command line, is to customize lsp-scala-server-command and lsp-scala-server-args.

Does it work?

metals describes itself as "work in progress". Temper your expectations, cheer them on, and help if you can. Though many lsp-mode features are not yet implemented, those that are appear to be working well. Kudos to the metals team.

Some of this is too nuanced to fit in a boolean. Some of this may be me my misunderstanding. More user experience reports welcome.
