2 years ago Thanks for the report @agdt3. I want to guess that if everything else is working as expected Scalafix has downloaded fine, but there might just be an issue with clearing the message. In a file can you test the organize imports command to see if it works?
Also do you have metals.statusBarEnabled?

2 years ago Running :CocCommand editor.action.organizeImport does in fact re-organize my imports. So I guess its correct to say that Scalafix is installed, but just hasn't cleared the message. This is without metals.statusBarEnabled.
For reference, with metals.statusBarEnabled, the status bar just says Metals after a while (no reference to Scalafix).
With airline:
At this point it seems to be stuck compiling forever, evidenced by the fact that I can't seem to access the treeview.

2 years ago On an somewhat related question (to my install of metals), how do I debug hover functionality? It doesn't appear to be working for me and I'm not exactly sure if there's something I need to do to toggle it in neovim/iterm2. Is it even supported?

Ok, this is expected. If there are no new statuses after it's cleared it will just say "Metals" to let you know that it's attatched. I'd highly highly recommend using coc-metals with statusBarEnabled. Without it I've found the messages to be spotty, they don't always clear like you're seeing etc. Everything is better with using status. So it shouldn't be "compiling forever", but rather done. Is everything else working at that point?

What does your mapping for hover look like?

2 years ago Thanks for the tip about statusBarEnabled!
For hover, I have set up the normal command nmap <Leader>ws <Plug>(coc-metals-expand-decoration) and also tested it with nmap <space>w <Plug>(coc-metals-expand-decoration). Neither seem to do anything.
My config file is (but I've tried a more minimal version too):
{
"coc.preferences.formatOnSaveFiletypes": ["scala"],
"metals.statusBarEnabled": true,
"metals.superMethodLensesEnabled": true,
"metals.showInferredType": true,
"metals.showImplicitArguments": true,
"codeLens.enable": true
}I think however that there might be something wrong with my install. When I try to open the tree view protocol on a completely new project (created with sbt new scala/scala3.g8), I end up with this (both root and root-test are empty):

That mapping is only to expand the metals decorations found in worksheets. The generic hover you want to use is this one:

Actually atm, this is expected. The Tree View Protocol isn't yet supported in Scala 3

2 years ago Ah, K does work to display hover test and TVP isn't supposed to work. Thank you for clearing that up!
Describe the bug
After indexing and compiling my scala 3 project in neovim, the command bar always says:
[coc.nvim] Downloading scalafix⠇. The loading boxes do not move, the notification never goes away. metals doctor doesn't show any obvious issues. Its also worth noting that the build.sbt file does not have scalafix as a dependency, nor is there a.scalafix.conffile in the root.To Reproduce
Steps to reproduce the behavior:
For me, its just opening any scala file in neovim v0.5.1 with coc.nvim and coc-metals installed as per the guide.
Expected behavior
Scalafix is presumably required by metals, so it should finish installing eventually.
Screenshots
Installation:
Additional context
coc.nvimorcoc-metalsrepos, but given that this is (probably) ametalsdependency, it might also be an issue here..metals/metals.logdoes not mention scalafix or any errors (beside lack of build target)Search terms
