var'aq is a programming language based loosely upon the grammatical structure of the Klingon language. It was created as part of a speculative exercise in imagining what the computer culture of the fictional Klingon race might be like, and was created by Brian Connors and Chris Pressey c. 2000.

The language is a stack-based language based loosely on PostScript, with aspects of the Lisp language added for handling data structures.

The following keywords are currently supported:

tlhIngan Hol has names for the numbers and there are also pIqaD (the Klingon writing system) versions of those numbers:

||pagh|| wa'|| cha'|| wej|| loS|| vagh|| jav|| Soch|| chogh|| Hut|| wa'maH||
||0   || 1  || 2   || 3  || 4  || 5   || 6  || 7   || 8    || 9  || 10    ||

Sample Program

Name: hello, world
Dialect: English
Version: 5 June 2000
Comments: Not the canonical var'aq "hello, world";
          actually prints "What do you want, universe?" in Klingon

~ nuqneH { ~ 'u' ~ nuqneH disp disp } name
nuqneH
