In this video I demonstrate the use of command-line tools to interactively explore Haskell source code. The tools provide a fluid development experience but can be tricky to configure. This talk covers their use, configuration, and integration with an editor.

Haskell Source Navigation

Summary

• Types provide more than just safety
• Haskell has enough structure to support sophisticated tools
  • Jump to symbol definitions
  • Find all uses of functions
  • Get (good) linting suggestions
  • Interactive error checking
  • Finding docs by type or name
  • Autocompletion from dependencies
  • Code formatting
• Getting into the tools themselves, below the editor layer
  • hasktags
  • codex
  • hscope
  • hoogle
  • hoobuddy
  • Alfred shortcuts
