My .vimrc is pretty basic (I guess), only julia formatter, julia vim, coc-julia, coc.nvim and some extras like nerdtree, slime and so on.

Any idea what could be the problem?

use PackageCompiler.jl to compile a sysimage of LanguageServer.jl.
:CocCommand julia.CompileLanguageServerSysimg
You may have to install PackageCompiler if not exists.(Pkg.add)

I tried to run :CocCommand julia.CompileLanguageServerSysimg after installing PackageCompiler, but I got this

[coc.nvim]: Error on notification "runCommand": Command: julia.CompileLanguageSer
verSysimg not found

I was following a few weeks ago these instructions, and I uninstalled the coc-julia (because they didn’t mention installing it in the forum). My concern now, is I am getting missing references in different parts of the code. Like this one.

So I am still stuck with these hahah

I’m facing exactly the same problem.

Did you got any updates about it?

indymnv · July 1, 2023, 1:57am

Hi!, I solved this problem by going on another path. Now I am using Neovim and instead of COC, I am using the LSP. I am not sure if it’s useful for you, but this was my process.

Install Neovim
Created an init.lua and just keep simple using the kick starter, which consider the most basic stuff to use.
In the init.lua also I added julia for the treesitter and the julials = {} for localservers
Finally, to set up the language server protocol, you will need to create the sysimage, you can follow the instructions considering in this discussion
With that should be enough, and you can consider adding other stuffs you need like vim-slime for example.

Finally, if you open a Julia file it should take a few seconds to prepare the lsp and you can start working with that.

Hope that can help you.

Works for me. Launch Julia in the specific project \usr\bin\julia project=.config/coc/extensions/node_modules/coc-julia/server. Then check if LanguageServer.jl package is installed : Pkg.status().

In my case it was there but not downloaded so I ran Pkg.instantiate() to download it and worked. You’ll be prompted to run Pkg.instantiate() all packages are not downloaded. run it anyway and might work.

Although I also had installed PackageCompiler.jl but didn’t need to do anything with this.
