Worked on the nvim-treesitter/nvim-treesitter repository to improve the reliability of parser installation for Perl and Pod grammars. Addressed a core issue by ensuring the parser-generation workflow tracks the default main branch instead of the release branch, which allows the correct grammar.json to be used during parser creation. This change reduced installation failures and enhanced the stability of syntax highlighting and code analysis for users relying on these grammars. The work involved Lua scripting, parser development, and ongoing software maintenance, focusing on backend improvements rather than new features, and contributed to a more consistent parsing layer across environments.
