`LanguageServer.jl` can be installed with `julia` and `Pkg`:
```sh
julia -e 'using Pkg; Pkg.add("LanguageServer"); Pkg.add("SymbolServer")'
```
The default config lazily evaluates the location of the julia language server from the your global julia packages.
This adds a small overhead on first opening of a julia file. To avoid this overhead, replace server_path in on_new_config with
a hard-coded path to the server.
```lua
require'lspconfig'.julials.setup{
on_new_config = function(new_config,new_root_dir)
server_path = "/path/to/directory/containing/LanguageServer.jl/src"
cmd = {
"julia",
"--project="..server_path,
"--startup-file=no",
"--history-file=no",
"-e", [[
using Pkg
Pkg.instantiate()
using LanguageServer
depot_path = get(ENV, "JULIA_DEPOT_PATH", "")
project_path = let
dirname(something(
## 1. Finds an explicitly set project (JULIA_PROJECT)
Base.load_path_expand((
p = get(ENV, "JULIA_PROJECT", nothing);
p === nothing ? nothing : isempty(p) ? nothing : p
)),
## 2. Look for a Project.toml file in the current working directory,
## or parent directories, with $HOME as an upper boundary
Base.current_project(),
## 3. First entry in the load path
get(Base.load_path(), 1, nothing),
## 4. Fallback to default global environment,
## this is more or less unreachable
Base.load_path_expand("@v#.#"),
))
end
@info "Running language server" VERSION pwd() project_path depot_path
server = LanguageServer.LanguageServerInstance(stdin, stdout, project_path, depot_path)
server.runlinter = true
run(server)
\]\]
};
new_config.cmd = cmd
end
}
```
You can find the path to the globally installed LanguageServer.jl package with the following command:
```bash
julia -e 'print(Base.find_package("LanguageServer"))'
```
Note: the directory passed to `--project=...` should terminate with src, not LanguageServer.jl.
