The ghc-vis User Guide
ghc-vis is a tool to visualize live Haskell data structures in GHCi. Evaluation is not forced and you can interact with the visualized data structures. This allows seeing Haskell’s lazy evaluation and sharing in action. Functional programming languages like Haskell offer a way to write well-structured software, which is easy to understand and still performs well. In order to achieve this one has t

Visualize live data structures in GHCi. Evaluation is not forced and you can interact with the visualized data structures. This allows seeing Haskell's lazy evaluation and sharing in action. See https://dennis.felsing.org/ghc-vis/#basic-usage for the basic usage of ghc-vis or watch a short video demonstrating how it can be used with GHCi's debugger: https://dennis.felsing.org/ghc-vis/#combined-deb
GHCi debugger を使ってみた - khibino blog
Haskell Advent Calendar 2011 のためのエントリです。 最近、会社でも Haskell を開発のメンバーで使っていくことに正式に決まりました。 Haskell のプログラムをデバッグするときにデバッガーのようなツールを使うことが できるのか社内で質問されたので調べてみました。 GHCi debugger 公式のドキュメント http://www.haskell.org/ghc/docs/7.0.4/html/users_guide/ghci-debugger.html や その翻訳 http://www.kotha.net/ghcguide_ja/7.0.4/ghci-debugger.htmlを 参考にしながら試してみて、私なりに理解した内容を紹介しようと思います。 mkothaさん、すばらしい翻訳をありがとうございます。 さっそく、GHCi debugger

Sat, 18 Oct 2014 Haskell : A neat trick for GHCi Just found a really nice little hack that makes working in the GHC interactive REPL a little easier and more convenient. First of all, I added the following line to my ~/.ghci file. :set -DGHC_INTERACTIVE All that line does is define a GHC_INTERACTIVE pre-processor symbol. Then in a file that I want to load into the REPL, I need to add this to the t
