🔬 Setup Julia in Neovim

short guide about setup Julia

This Week I try to setup Julia Development in Neovim in linux/wsl, I use lazyvim (read the installation on lazyvim doc).

after initial setup in lazyvim, you need install julia-lsp with Mason then search julia-lsp it will install julia lsp on your ~/.local/share/nvim/mason/packages/julia-lsp

• install juliaup (i use yay, pacman not provide it) yay -S juliaup --noconfirm
• then install latest stable version with juliaup add <version>, to list version run juliaup list
• after install, make latest stable version as juliaup default with juliaup default <version>
• next go to julia folder cd ~/.julia/environments/v1.11/
• it may contain mainfest.toml and project.toml, if not, try to create new project then add package in this folder (as shown below)

[deps]
GLMakie = "e9467ef8-e4e7-5192-8a1a-b1aee30e663a"
Makie = "ee78f7c6-11fb-53f2-987a-cfe4a2b5a57a"
PackageCompiler = "9b87118b-4619-50d2-8e1e-99f35a4d4d9d"

• next run julia with julia then enter Pkg with ]
• active current env with activate .
• and run precompile
• it will compile all needed package for your project
• then try to create or open project outside of .julia
• when you first open julia project it may run slow / timeout, because the server itself is not compiled yet, julia will compile (based on your system it may slow or fast), then after first compile it able to indexing your project
• in neovim you can see lsp log with LspLog

• if first trigger compiling not work from neovim (by opening julia file), try to trigger by run the server from mason folder ~/.local/share/nvim/mason/bin then ./julia-lsp ~/path/to/external/julia/project
