I'm working on a Mac, here is a list of things I know I needed to install, all of which I did via homebrew:
- NeoVim
- Vundle (I've heard
vim-plugis more modern, but Vundle is working fine for me so far) - OneDark theme files? Check the git repo for more info.
- Scala
- SBT
- Scalafmt
- NPM
- Node
- Yarn
- Coursier (might have been a direct download?)
- OpenJDK - I'm using 11, metals supports 8 or 11 at the time of writing.
Clone this repo into ~/.config/nvim/ so that init.vim is at ~/.config/nvim/init.vim as is coc-settings.json.
In your terminal, open nvim - I often open nvim ~/.config/nvim/init.vim only because if this doesn't work I'm probably going to be tweaking the setting file again!
Type: :PluginInstall then :CocInstall - think you only have to do that last one once.
Restart NeoVim.
Look at the plugins in the config file. I've added a bunch of things for IDE-like workflow tools but it's left to the reader to check the docs for each one. FZF and Nerdtree are important, go read up.
The Scala metals keyboard shortcuts are largely in the config file or in the link above... because it gives you the config file...
I'm using the automatic update / install version of Metals via CoC (conqueror of completetion or something), other options on the link.
I had a problem where my scala project was in a sub folder of the git repo and vim/coc/metals was confused because it assumes the workspace starts at the git repo. I'm hoping I've fixed this in the coc-settings.json file, but a workaround is to drop a folder called .vim next to your build.sbt file and then it does the right thing.
