lsp-metals was extracted out of lsp-emacs into a separate package. This
change adds that separate package to the scala module when the lsp
feature is selected.
Fixeshlissner/doom-emacs#3362
Ensime just went missing from everywhere.
On [[ensime.github.io]], they encourage to switch to metals -
a new Scala language server already supported by lsp-mode.
This commit:
- removes ensime completely
- adds a doctor.el to check for metals-emacs binary
