Explore Haskell code exploration techniques using Emacs in this 30-minute conference talk from EmacsConf 2022. Dive into the fundamentals of Haskell programming, including its structure and syntax, before delving into the concept of code explorers. Learn about various tools and features available in Emacs for Haskell development, such as Haskell mode, declaration jumping, reference finding, and the Haskell language server. Discover the power of Hoogle, Hackage, and the Haskell Code Explorer through live demonstrations. Gain insights into advanced topics like monads, web clients, and user freedom in Haskell development. Explore the hc.el package and its integration with Emacs, including features like Eldoc support, identifier searching, and help buffer integration. Delve into Haddock documentation, Servant framework, and Org mode integration. Finally, learn about navigation techniques and bidirectional exploration in Haskell code using Emacs.
