Hi, I am developing a package to which I have added an example folder including some additional dependencies in a separate `Project.toml` file. The overall structure looks more or less like

```julia
├── examples
│ ├── first_example.jl
│ ├── Manifest.toml
│ └── Project.toml
├── Manifest.toml
├── Project.toml
├── README.md
└── src
    └── MyPackage.jl

```

For editing I use helix with the following language server configuration

```julia
[language-server.julia]
command = "julia"
args = [
 "--startup-file=no",
 "--history-file=no",
 "-e",
 """
 using Pkg;
 using LanguageServer;
 runserver()
 """,
 ]

```

While in `MyPackage.jl` the LS works as I would expect, in `first_example.jl` I keep getting `Missing reference: ...` warnings. If I activate the environment in my examples folder I can run `first_example.jl` without any issues so there must be something wrong with my LS configuration.

Interestingly enough, the LSP starts correctly in the examples folder and I do get `[ Info: Package MyPackage (<UUID>) is cached` along with all other dependencies at the start and `[ Info: Loaded all packages into cache in 0.84s` at the very end, so I have no idea what might be the problem.

This kind of workflow should be supported by LS, so there must indeed be something wrong with the way you set things up.

You didn’t provide much details about the way you created the environment in `examples`. Did you use something like `Pkg.develop(path="..")`?

Also, I’m not familiar with helix at all, but do you know in which directory it starts the language server? This is important because the language server current working directory will be used to determine the environment in which the language server operates.

It may not have anything to do with your issue, but seeing how short you LS invocation is, I can’t help wondering how it works. In which environment is `LanguageServer` installed?

Yes. I created an empty `Project.toml` file, started julia in the examples folder, activated the environment using `] activate .`, added all other dependencies except `MyPackage` using `] add` and then ran `] develop ..`

> [@ffevotte](#):

It does seem to start in the current directory as there is a difference in the packages being loaded depending on if I start helix in `MyPackage` or `MyPackage/examples`.

`LanguageServer` should be installed in the main environment of the “user”. It is certainly not installed in `MyPackage` nor `MyPackage/examples` and to install it globally I expect sudo privileges would be required.

If there is a different invocation you’d recommend I can try it.

OK, this is what I do too; it should work.

If by “current directory” you mean the directory in which helix is started, this might be (part of) the problem. AFAIK `LanguageServer.runserver()` will try to determine the current project by

1. looking in `ARGS[1]` (but here you don’t provide any command-line argument)
2. working its way up from `pwd()` until it finds a `Project.toml`.

So you’d need to either ensure that LS is started in the directory of the file you’re editing. Or you could perhaps give an additional command-line arg to tell LS where to find the relevant `Project.toml`.

This might require some support from helix. For example, for emacs in `eglot-jl` all this logic is done in the emacs side of things: we try to determine which project the file currently being edited belongs to, and provide this to the LanguageServer.

> [@lieskjur](#):

This should be fine. But other ways are possible. For example, again in `eglot-jl` we have `LanguageServer` and `SymbolServer` installed in a small, dedicated environment. This makes it less likely that globally installed packages interfere with LS.

I am almost certain the LS starts in the correct directory and sees the `Project.toml` as I do get different (and correct) packages listed as cached — `[ Info: Package <PackageName> (<UUID>) is cached` — by the LS, depending on if I start helix in `MyPackage` or `MyPackage/examples`.

OK, this makes sense. I tried doing the same but I still get the `Missing reference:` warnings.

* * *

Maybe, just to make sure I didn’t mess-up somewhere in my project, this is the [package](https://github.com/JurajLieskovsky/IterativeLQR.jl/tree/main) where I’m trying to get it to work. So if you could open `examples/cartpole_swing_up/optimization.jl` and check that you don’t get any `Missing reference` warnings, the problem would really be somewhere in the config/LS/editor.

Yes, I can confirm that everything works on my side (Emacs with eglot-jl handling the LS stuff). What I did:

```shell
shell$ git clone https://github.com/JurajLieskovsky/IterativeLQR.jl/

shell$ cd IterativeLQR.jl/examples

shell$ julia --project
(examples) pkg> dev ..
   Resolving package versions...
   Installed FFMPEG ─ v0.4.2
   Installed GR_jll ─ v0.73.8+0
   Installed GR ───── v0.73.8
[...]

shell$ emacs cartpole_swing_up/optimization.jl

```

Of course, at first I did get `Missing reference` warnings all over the place, but once LS had some time to index everything, the warnings disappeared. Here is a screenshot of LS listing all references for `IterativeLQR.nominal_trajectory`

 ![Screenshot_2024-10-24_23-45-54](https://global.discourse-cdn.com/julialang/original/3X/2/c/2c350d055b82c8f9e83cff26bfdfc99185f44d73.png)

FYI, here is `LanguageServer`’s startup summary, showing it took around 40 seconds on my machine for it to get fully operational:

There seem to be some extra steps performed in your LS startup, specifically

> [@ffevotte](#):
>
> ```julia
> [stderr] 3.5914 - LSP/workspace/didChangeConfiguration (0.22061s since last event)
> [stderr] 3.9803 - LSP/textDocument/signatureHelp (0.38892s since last event)

> [stderr] 4.9816 - LSP/textDocument/documentHighlight (0.61376s since last event)
> 
> ```

The odd thing is that I the difference is still there even after I used `eglot-jl` for my LS configuration

```toml
[language-server.julia]
command = "julia"
args = [
 "--project=/home/juraj/eglot-jl",
 "/home/juraj/eglot-jl/eglot-jl.jl"
]

```

I would assume, the only difference in the startup is that I don’t have a `depot_path` set

```log
┌ Info: Running language server\n
│ env = \"/home/juraj/eglot-jl/Project.toml\"\n
│ src_path = \"/home/juraj/OneDrive/u12110/IterativeLQR/examples\"\n
│ project_path = \"/home/juraj/OneDrive/u12110/IterativeLQR/examples\"\n
└ depot_path = \"\"\n

```

Good idea to use `eglot-jl`’s julia script to launch the server inexactly the same conditions!

I wouldn’t worry about the depot path. It’s rarely used, and in any case I don’t set one either.

I would now assume that remaining differences come from the LSP client, i.e. Emacs’ (or VS Code’s) LSP implementation _vs_ Helix’ implementation.

In case it would help investigating this, here is a pretty representation of the first request sent by `eglot` to initialize the language server:

Edit: The issue does indeed seem to be in the workspace folder

I suppose the correct `Project.toml` file is found but helix starts the LS in the base folder of the package?

Remembering that helix likes to base its workspace based on the location the containing git repository (workspace directory seem to differ from the working directory which might explain why the correct `Project.toml` file was loaded) I created a copy of my package where I deleted the `.git` folder and now the LS works.

So I’ll have to figure out a way which does not require me to delete the `.git` folder but I think that’s specific to helix. @ffevotte thank you for all your help.

The solution seems to be adding a `.helix/config.toml` file to the root of my package

```toml
# .helix/config.toml
[editor]
workspace-lsp-roots = ["examples"]

```

and then starting helix in the `examples` folder. This results in the LS starting with the `examples` folder as its “LSP root”.

Considering this I was wondering if I would have to use a similar solution for a potential `test` folder but to my surprise the LS works in this case even if the “LSP root” in helix remains the base directory of the package.

Test dependencies benefit from a special treatment, at least in `Pkg`. Maybe LS also handles them specifically?

However, you’re probably going to have to use the same kind of solution for your `docs` folder if you need LS to work in it.
