Synopsis: Programming language with non-linear pattern-matching against non-free data
Description:
An interpreter for Egison, a **pattern-matching-oriented**, purely functional programming language.
We can directly represent pattern-matching against lists, multisets, sets, trees, graphs and any kind of data types.
.
We can find Egison programs in @lib@ and @sample@ directories.
This package also include Emacs Lisp file @elisp/egison-mode.el@.
.
We can do non-linear pattern-matching against non-free data types in Egison.
An non-free data type is a data type whose data have no canonical form, a standard way to represent that object.
It enables us to write elegant programs.
.
/Twin Primes/
.
We can use pattern-matching for enumeration.
The following code enumerates all twin primes from the infinite list of prime numbers with pattern-matching!

.
/Poker Hands/
.
The following code is the program that determines poker-hands written in Egison.
All hands are expressed in a single pattern.

.
/Mahjong/
.
We can write a pattern even against mahjong tiles.
We modularize patterns to represent complex mahjong hands.

.
/Graphs/
.
We can pattern-match against graphs.
We can write program to solve the travelling salesman problem in a single pattern-matching expression.

Aren't thsese exciting?
We can run these demonstrations on our website!
Please view and try more demonstrations!

Egison makes programming dramatically simple.
Please enjoy Egison!
