Sifflet and sifflet-lib 1.2.5 are now available on Hackage.
This is a compatibility release for GHC 7.4.1.

Sifflet is a visual, functional programming language
and support system for students learning about recursion.
Sifflet programmers define functions by drawing diagrams,
and the Sifflet interpreter uses the diagrams to show how
function calls are evaluated.

Sifflet-lib is the library containing many modules of the sifflet 

What's New

June 1, 2012: Version 1.2.5 provides compatibility with GHC 7.4.1.

About Sifflet

Sifflet is a visual, functional programming language
intended as an aid for learning about recursion.

*   A picture explains Sifflet better than words:
    please see the screenshot showing how to evaluate 3!:

*   Features:
    -   Visual editor.
    -   Visual tracer/debugger which shows how recursive and
        other function calls are evaluated.  To support active learning
        and avoid screen clutter, Sifflet displays only
        as much of the computation as the user requests.
    -   A carefully crafted tutorial with 31 pictures and about as many pages.
    -   Number, string, and list data types.
    -   A small collection of primitive functions.
    -   Runnable examples of compound functions.
    -   Sifflet functions can be exported to Scheme, Python 3, and Haskell.
