Install

NOTE:

If using a nix-provided nvim, coc-solargraph may fail to start within vim because directories are not writable.

If you are not getting completions, see :CocInfo.

gem install neovim
gem install solargraph
gem install solargraph-rails --pre  # if using rails

:CocInstall coc-solargraph   " uses solargraph on backend

For each project:

# add docs from project's gems to solargraph
solargraph bundle

Make sure to see ruby solargraph instructions for additional optimizations.

Usage

• ctrl+space triggers coc completion.
• ctrl+n/p will continue to use vim's builtin keyword completion.
