Kipple is a minimalistic programming language where all data manipulation is done with stacks of integers. Kipple's only features are the stacks, four operators and one control structure, but it is nonetheless Turing-complete. My primary source of inspiration for creating Kipple was the programming language Brainfuck which introduced me to the wonderful world of Esoteric programming languages. For details about the language see the specification, or check out the examples below.
The word kipple is taken from the excellent book Do Androids Dream Of Electric Sheep by Philip K. Dick.
Questions, comments, bug reports etc. can be sent to me at rune@krokodille.com. If you write anything cool in Kipple, please let me know! I'll be happy to put it here on this page.

The site is online again.

Added two programs by Jannis Harder to the samples section. One who squares a number read from input, and one who computes the digital root.
Wow! Daily updates. Where will this end...

I've uploaded an early version of the Kipple 05 specification. Subject to change without notice.
Also, Jannis Harder has written a C interpreter which beats the crap out of mine when it comes to performance. Get the latest version here.

Added a prime number generator made by Jannis Harder to the samples section.

The web site is up again. I've added a linux binary version of the interpreter (compiled with gcj) for download, for people who don't wish to install Java. Get it here (requires glibc 2.3.2).

Gregor Richards has written the world's second Kipple interpreter. And he did it in ORK! The interpreter can be found here.

My web server crashed last week. It's up and running again now, but since I don't know what caused the crash, I don't know for how long...
In other news, Keymaker has made a great quine in Kipple. It can be found in the samples section. I've also added a nice bubblesort program made by DeathPing a while back.

Fixed a bug in the interpreter which caused the applet version to not clear the stacks between executions. Also added a clarification to the Specification about what happens with statements of type a+a (Thanks to Daniel Cristofani for pointing this out).
