Worked on enhancing Fortran language support in the helix-editor/helix repository by expanding language detection to recognize uppercase Fortran file extensions and refining syntax highlighting. Leveraged configuration skills and code parsing expertise to update the Tree-sitter grammar, which improved parsing accuracy and folding behavior for Fortran files. Focused on TOML and scm languages to ensure robust integration with the editor’s existing language support framework. The work addressed gaps in file extension recognition and improved the overall editing experience for Fortran developers. Delivered one feature during the month, demonstrating depth in syntax highlighting and language grammar refinement without addressing bug fixes.
