Worked on enhancing Haskell developer tooling by expanding Cabal support within the haskell-language-server and haskell/cabal repositories. Delivered Cabal autocompletion for autogen-includes and autogen-modules fields across all major cabal stanzas, implementing new completer functions and comprehensive tests to ensure robust code completion in Haskell IDE environments. Introduced NFData instances for core Cabal data types, enabling reliable data serialization for HLS plugin integration and reducing runtime errors. Focused on improving configuration accuracy and developer productivity by strengthening IDE integration and plugin stability. Utilized Haskell, Cabal, and the Language Server Protocol to deliver features supporting maintainable, configuration-ready Haskell project workflows.
