Using LanguageServer.jl with eglot in emacs

4aHxKzD · January 18, 2020, 11:54am

After installing eglot-jl, opening a julia-mode buffer, calling init-eglot-jl and eglot, I get the following error:

[jsonrpc] Server exited with status 1
error in process sentinel: eglot--error: [eglot] -1: Server died
error in process sentinel: [eglot] -1: Server died

I noticed that you initialize LanguageServerInstance with 6 arguments, but I checked the package LanguageServer,jl and the constructor for LanguageServerInstance only accepts 5 arguments. I also tried removing the last argument “Dict()” and was able to overcome this error. I still have others though.

That’s strange. The signatures of LanguageServer.jl may very well have changed, but the eglot package should have things pinned to a working version of the language server. Could you try instantiating the environment in the REPL and see if it works without modifying the arguments? Maybe using LanguageServer is picking up the wrong version despite the Manifest.toml.

In general, for troubleshooting, please post the output of the eglot stderr buffer. It’s much more useful for me to tell what’s going on.

This was an error on my end. I wasn’t testing the version that I thought I was testing. Patch release v1.1.1 should have this fixed. Thanks for bringing it to my attention. Please post or file issues for the other errors you’re running into.

4aHxKzD · January 20, 2020, 4:07pm

When you define eglot-jl-default-environment version 1.2 of Julia is assumed, but right now we are at 1.3, should I change it for the package work?

Vasily_Pisarev · April 13, 2020, 11:40am

I have a problem of LanguageServer crashing soon after start, because eglot sends it nil where an array is expected.

So far, I added Base.length(::Nothing) = 0 to eglot-jl.jl as a workaround. Not sure which package is responsible for the bug - eglot-jl, eglot or LanguageServer.

non-Jedi · April 13, 2020, 12:01pm

Could you please give replication details? File it crashes on, versioninfo(), etc? In general, I’m happy to have bugs filed against eglot-jl and forward them upstream when necessary.

Vasily_Pisarev · April 13, 2020, 12:34pm

I hope that has the relevant information…

I’ve updated eglot-jl to use the latest release of LanguageServer.jl (so it’s now compatible with julia 1.4) and have been using it for the past 24 hours with no issues so far. I’ve also cleaned up the code for locking eglot-jl to a specific version of LanguageServer.jl so that it should get the correct version even if LanguageServer.jl is installed in your default environment.

Big kudos to @ZacLN and @davidanthoff for the work on the language server in recent months. It seems much more stable to me now. In particular, the parallel symbol server caching is a big win for usability (no longer have to wait multiple hours for the symbol server to process all dependencies before getting a usable language server).

Give it a try and let me know if any problems. If you’ve been using lsp-julia, this a great chance to give the other side of the fence a try until julia 1.4 support is ironed out. I’ve updated the LanguageServer.jl wiki with a description of the capabilities that are currently working.

I’ve been using eglot with eglot-jl lately and it has improved a lot since I first tried it. Now it helps instead of getting in the way!

non-Jedi · May 4, 2020, 12:44pm

Since this thread keeps popping up (mostly my fault) and I’m unable to edit the OP anymore, would somebody with discourse moderator rights be willing to edit this link into the OP?

Glad it’s working better for you now; I’ve experienced roughly the same thing in the past month (no longer a hinderance).

non-Jedi · June 5, 2020, 12:47pm

@ffevotte has contributed tooling to make using LanguageServer.jl compiled by PackageCompiler simple with eglot. I would appreciate if anyone who is interested in the significantly alleviated startup time this gives (from 15 seconds down to less than 1) could test out his branch before I merge to master so that we can work out any bugs.

4aHxKzD · June 5, 2020, 2:52pm

based on a quick test, works crazy fast for me!

ffevotte · June 5, 2020, 4:43pm

Glad to hear that! What type of system did you try this on?

I’d really like it if a MacOS user could try it, since I have not been able to test on this OS…

4aHxKzD · June 5, 2020, 4:49pm

manjaro linux, but I’ll try it on macOS when I have the time.

dlakelan · June 5, 2020, 11:55pm

This sounds all kinds of awesome… I’m a more or less old-school emacs user and haven’t kept up with newer emacs features… How do I get this installed effectively?

I installed eglot-jl from MELPA, am in a julia buffer with julia mode and company mode on, and I get:

[jsonrpc] Server exited with status 1
error in process sentinel: eglot--error: [eglot] -1: Server died
error in process sentinel: [eglot] -1: Server died

Running julia 1.4.1 and emacs-gtk 1:26.3+1-2 on Debian testing.

non-Jedi · June 5, 2020, 11:59pm

Could you post the contents of the "EGLOT (Env/julia-mode) events buffer please?

dlakelan · June 6, 2020, 12:01am

Sure!

I tested the sysimage branch on MacOS, it seems to work and indeed accelerate the startup time.

Not sure whether it matters but I tested it only on a mock project .

I am having some problems with the language server crashing on a real project (not related to this branch) which are probably related to LanguageServer.jl. I will try to open an issue. Is there a way to make eglot to not reconnect after a server crash? I would like to provide the relevant details from the event buffer but eglot just keeps reconnecting (and the server keeps crashing) swamping the event buffer with new info.

Thanks for testing!

You can try to customize eglot-autoreconnect:

(setq eglot-autoreconnect nil)

Does that EGLOT events buffer give any clue as to what happened?
