No support for workspaces (aka monorepo)

[luc-j-bourhis]

My situation is a Project.toml in a top directory like:

[workspace]
projects = ["PackageA", "PackageB", ...]

[deps]
PackageA = "..."
PackageB = "..."
...

and then "PackageA/Project.toml", "PackageB/Project.toml", … are just of the vanilla kind. This will result in a single "Manifest.toml" in the top directory, that merges the dependencies of all the dependencies listed in "PackageA/Project.toml", "PackageB/Project.toml", …

But then, when I open a source file inside "PackageA" that features using FileIO for example, hovering over "FileIO" does not show anything, and I don't get any completion of the symbols exported by FileIO either (e.g. File, format, etc). Apart from that, LSP works superbly in my SublimeText. Is that actually a limitation of the LSP server itself? Or is there a configuration tweak I am missing? The only configuration I touched is User/LSP-julia.sublime-settings:

{
    "julia_executable_path": "/Users/luc/.juliaup/bin/julia",
    "julia.lint.missingrefs": "all",
    "enabled": true,
}

I tried to use the command LSP-Julia: Change Current Environment: it finds the top directory but selecting that does not solve my problem.

I think workspaces are a new feature in Julia 1.12, and to be honest I haven't used that feature yet, so I'm not really sure. But I assume it's a limitation of the language server, because there were very few commits over the last 1-2 years and I've seen things not working properly before when multiple submodules are used in a Julia project.

In general I would recommend to also give the newer JETLS server a try, which is very actively depeloped and has some more cool features that work out of the box. It still has some rough edges, like diagnostics behaving a bit weird (some diagnostics are only updated when saving the file, because analysis via JET can take a few seconds for bigger projects), and signature help also sometimes doesn't seem to work fully reliable. But it looks like the author is currently working on displaying the inferred types of variables and functions in the hover popup and for inlay hints, which seems like it will be a very useful feature.

I haven't tested, but perhaps workspaces work correctly in JETLS.

Instructions for (manual) installation are at https://lsp.sublimetext.io/language_servers/#jetls and here is an example config with more settings (most of it default values):

{
    "JETLS": {
        "enabled": true,
        "command": ["jetls", "serve", "--socket=${port}"],
        "tcp_port": 0,
        "selector": "source.julia",
        "settings": {
            // "jetls.full_analysis.debounce": 1.0,
            // "jetls.full_analysis.auto_instantiate": true,
            // "jetls.diagnostic.enabled": true,
            // "jetls.diagnostic.all_files": true,
            // "jetls.diagnostic.allow_unused_underscore": true,
            "jetls.diagnostic.patterns": [
                {
                    "pattern": "lowering/unused-local",
                    "match_by": "code",
                    "match_type": "literal",
                    "severity": "off"
                },
            ],
            "jetls.completion.latex_emoji.strip_prefix": false,
            "jetls.completion.method_signature.prepend_inference_result": false,
            "jetls.code_lens.references": true,
            "jetls.code_lens.testrunner": true,
            "jetls.inlay_hint.block_end.enabled": true,
            "jetls.inlay_hint.block_end.min_lines": 25,
        }
    },
}

Thanks for the suggestion and the config, I will report back.
