Version 4 (modified by judah, 9 years ago)



The haskeline library provides a user interface for line input in command-line programs. This library is similar in purpose to readline, but since it is written in Haskell it is (hopefully) more easily used in other Haskell programs.


  • Provides a rich line editing interface which may be customized in a ~/.haskeline file.
  • Runs on POSIX-compatible systems, using the terminfo library to support non-ANSI terminals.
  • Runs on Windows using MinGW (Cygwin support is TODO).
  • Supports Unicode cross-platform (UTF8-only on POSIX, for now).
  • History recall and incremental search.
  • Custom tab completion functions which may run in an arbitrary monad.
