Haskell Debugger for GHC 9.14
Announcing the brand new Haskell Debugger, which I've been working on for the past year. It is first compatible with GHC 9.14.
Welcome to Romes' Musings
I work at Well-Typed as part of the Glasgow Haskell Compiler Team. I've got a Master's degree from Faculdade de Ciências e Tecnologia in Lisbon -- the thesis was on type-checking linear types in GHC's Core and throughout its optimisation pipeline.
I try to write interdisciplinary articles, am a Haskell enthusiast and GHC contributor. Besides work, I'm developing a language to design distributed algorithms, a shader-centric and type-heavy 3d renderer / game engine, trying to get e-graphs into GHC, and recently have been working on a deck of cards to learn Japanese. You can find below my latest posts.
