Yhc/Yhe

Part of Yhc (Download)

Yhe is a command-line style tool in the vein of Ghci and Hugs. It consists of a command-line tool, yhe, and a GUI, Gyhe, written using Gtk2hs. It was mostly written by Mike Dodds.

Features of Gyhe:

• Single and multi-line input
• Cross-platform gui (works on Linux, Windows and MacOS)
• Syntax-highlighting of input with gtksourceview widget

Trying Gyhe

Gyhe is still very much alpha software - if you need a stable haskell command-line gui, I'd suggest you use WinHugs. That said, if you want to try Gyhe:

• Download the yhc-devel branch from darcs
• Ensure that you have the development version of Gtk2hs installed.
• Change directory to yhc-devel/src/interactive/
• Run 'make gui'

...and the gyhe executable should be created in yhc-devel/inst/bin/. Any comments or patches you have would be welcome.

Todo List

Sensible short-term aims:

• Add lazy evaluation - currently we only get a result after the program terminates
• Add file URI support to link to a file and load a text editor. Currently waiting for parsable error messages from the Yhc developers.
• Fix the makefile to detect the sourceview widget - at the moment it is always off at compile-time

Less sensible longer-term aims:

• Add clickable links into Hoogle
• Handle drag-and-drop events from other processes
• Add support for other compilers.
• Windows version, like WinHugs, using native widgets.
