Visual Studio Code Contributing to OSS

Visual Studio Code was officially made open source in November of 2015 and I immediately began building extensions for it. I had spent the summer as an intern working on internal tools for the Visual Studio Code team but the extensibility API had not yet been built so I got to learn with the rest of the community. I recognized that most of the effort was being put into extensions for javascript and javascript-adjacent areas such as TypeScript and Angular and I could provide more value if I pursued less crowded options. I was taking a couple classes that used Ruby and Haskell so I decided that’s where I would focus my effort. I started with a utility extension for converting between numeric bases, then created a couple linters, and most recently have been working to add more sophisticated language support for Haskell leveraging a tool called ghc-mod. Along the way I’ve also made a handful of pull requests against the actual Visual Studio Code repository, related tools, and the docs. You can read more about my published extensions below.

  • Base Converter - A simple utility for converting between bases. i.e. Converting 5 in decimal to 101 in binary. (repo)
  • Ruby linter - Brings built in ruby linting capabilities to VS Code. (repo)
  • Haskell Linter - Brings hlint suggestions to VS Code and provides code actions to turn the suggestions into code changes. (repo)
  • Haskell ghc-mod - Utilizes a tool called ghc-mod to bring type and definition information for haskell projects to VS Code. (repo)
