Hey, I’m trying to set up matlab lsp language server as described here: matlab language server

I’m using this setting:

"matlab": {
               "command": ["/path/to/lsp-matlab", "--stdio", "--matlabInstallPath '/usr/local/MATLAB/R2023a'"],
               "enabled": true,
               "selector": "source.m"
           }

where the lsp-matlab file has this:

#!/usr/bin/env bash

node /home/user/software/MATLAB-language-server/out/index.js $@

But nothing happens. Can you tell what I’m doing wrong?

Regards

source.matlab, to see the scope, press ctrt+alt+shift+p

after doing that I got this log:

That said it’s now starting. As for how to properly set it up, you may have to ask its author, read its docs, or worstly, read its source codes.

**kira** · December 6, 2023, 2:14pm

Is there any other option in the configuration that could help?

**jfcherng** · December 6, 2023, 2:39pm

This is still my answer. This is not LSP plugin issue. The first thing is to know how to start the server properly (what cli command should be used? what initializationOptions should be used? what settings should be used?), which is not LSP-related and not ST-related.

**jwortmann** · December 6, 2023, 3:25pm

Currently, this project is not intended to be installed on its own, however that may change in the future.

It seems to be another case of “LSP is for VSCode, we don’t care about other editors…”

Is there any error message from the server in the log panel (LSP: Toggle Log Panel from the command palette)?

**kira** · December 6, 2023, 3:48pm

yes, I got THIS (too long to post).

**rwols** · December 6, 2023, 5:47pm

Can you instead try the following command? Just a shot in the dark here.

"command": ["/path/to/lsp-matlab", "--stdio", "--matlabInstallPath",  "/usr/local/MATLAB/R2023a"]

**rwols** · December 6, 2023, 5:49pm

I see that you have a single file open due to 'workspaceFolders': None.

Can you instead try opening a root directory?

(I would expect single files to work nonetheless, since VSCode supports that as well).

**kira** · December 6, 2023, 6:10pm

what do you mean opening a root directory?
if you mean open a folder with sublime text, I updated the LOG:

**rwols** · December 6, 2023, 6:09pm

Looking at the neovim config,

it seems like you do have to open a directory rather than a file (which is weird since a None value for workspaceFolders is allowed per the spec.
it seems to expect some settings. I’m not quite sure whether these are initializationOptions or settings.

In case they are initializationOptions, try this:

        "matlab": {
            "command": [
                "/path/to/lsp-matlab",
                "--stdio",
                "--matlabInstallPath",
                "/usr/local/MATLAB/R2023a"
            ],
            "enabled": true,
            "selector": "source.m",
            "initializationOptions": {
                "MATLAB.indexWorkspace": true,
                "MATLAB.installPath": "/usr/local/MATLAB/R2023a",
                "MATLAB.matlabConnectionTiming": "onStart",
                "MATLAB.telemetry": false
            }
        }

In case they are server settings, try this configuration:

        "matlab": {
            "command": [
                "/path/to/lsp-matlab",
                "--stdio",
                "--matlabInstallPath",
                "/usr/local/MATLAB/R2023a"
            ],
            "enabled": true,
            "selector": "source.m",
            "settings": {
                "MATLAB.indexWorkspace": true,
                "MATLAB.installPath": "/usr/local/MATLAB/R2023a",
                "MATLAB.matlabConnectionTiming": "onStart",
                "MATLAB.telemetry": false
            }
        }

**kira** · December 6, 2023, 6:10pm

ok, let me try it

**kira** · December 6, 2023, 6:21pm

Hey, thatk you very much!!
using system settings didn’t crash even in a single file. It seems to be working fine, although I haven’t read what should do, is recognizing basic stuff like missing semicolon or non used variables.

**kira** · December 8, 2023, 7:38pm

I just put all together in this little REPO, with instructions on how to install the server.
