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.

Written by the indexing model from the issue text.

Description

bug

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.
