sifflet

Simple, visual, functional language for learning about recursion.

Sifflet is a visual, functional programming language. It is intended as an aid for learning about recursion. Sifflet users can make programs by drawing diagrams to connect functions and other units. Sifflet shows the intermediate steps of the computation on the diagram, and can expand function calls to show further details.

Installation

A. In a Cabal sandbox (bracketed parts are optional) (with the source distribution unpacked)

$ cabal sandbox init
$ cabal update

You will need this to build the Haskell gtk library if it is not already installed:

$ cabal install gtk2hs-buildtools

Continue:

$ cabal install --only-dependencies [--enable-tests]
$ cabal configure [--enable-tests]
$ cabal build [-j4]
$ cabal install

B. In a Cabal sandbox, directly installing from Hackage:

$ cabal sandbox init
$ cabal update
$ cabal install sifflet

1. Configure, either for system-wide installation:

   $ runghc Setup configure

   or for installation in a user directory:

   $ runghc Setup configure --user --prefix=~/where/to/install/

2. Build and install:

   $ runghc Setup build $ runghc Setup install
