Contributing to GHC 3: Hacking Syntax and Parsing
Too Long; Didn't Read
In <a href="https://mmhaskell.com/blog/2018/6/18/contributing-to-ghc-2-basic-hacking-and-organization" target="_blank">last week’s article</a>, we made more progress in understanding GHC. We got our basic development cycle down and explored the general structure of the code base. We also made the simplest possible change by updating one of the error messages. This week, we’ll make some more complex changes to the compiler, showing the ways you can tweak the language. It’s unlikely you would make changes like these to fix existing issues. But it’ll help us get a better grasp of what’s going on.
