During a one-month period, Anders Cristoffers upgraded MATLAB language support in the helix-editor/helix repository by updating the tree-sitter-matlab grammar. This work involved configuring the editor to use the latest grammar version, which improved MATLAB syntax parsing and highlighting, thereby reducing parsing errors and enhancing code editing reliability. Anders applied a minor version bump to ensure compatibility and maintainability within the project. The technical approach centered on configuration management using TOML, focusing on integrating upstream grammar changes. While the scope was limited to a single feature, the update addressed a clear need for more accurate MATLAB language support in Helix Editor.
