Description

Describe the bug
When passing a value starting with - to --matlabLaunchCommandArgs, the server exits with a Not enough arguments following: matlabLaunchCommandArgs error, while other strings work as expected.

To Reproduce
From the repository root (after building out/index.js):

  1. Run:

    node out/index.js --stdio --matlabLaunchCommandArgs "xxx"
    

    The server starts normally.

  2. Then run:

    node out/index.js --stdio --matlabLaunchCommandArgs "-xxx"
    

    The process exits with the following error (or similar):

    Not enough arguments following: matlabLaunchCommandArgs
    

Expected behavior
--matlabLaunchCommandArgs should accept arbitrary strings as its value, including strings that start with - (e.g. "-xxx"), and pass them through to MATLAB in the same way as "xxx".

Useful Information

  • MATLAB-language-server: current main (commit: 6c7e6b4)
  • Node.js: v24.11.1

Additional context
This looks like the value is not being counted as an argument for matlabLaunchCommandArgs, but I am not sure whether this is intended behavior or a bug in how the CLI options are parsed.

If you need additional information or logs, I can provide them.

Research direction

Build out/index.js and reproduce the two commands from the issue, then inspect the CLI argument parsing for --matlabLaunchCommandArgs. Verify that values beginning with '-' are accepted and passed through like other strings, while the existing command continues to start normally.
