Esoterische Programmiersprachen

• haben nichts mit Esoterik an sich zu tun
• verfolgen Konzepte fern der konventionellen Programmiersprachen
• sind nicht für den praktischen Einsatz entwickelt worden
• Anwendung z.B. als Proof of Concept
• oft nur Theorien/Ideen ohne wirkliche Implementierung
• können hohen akademischer Wert haben
  • sind aber oftmals einfach nur ein Witz

Sie können unterteilt werden in:

Befehlende Sprachen

Befehlende Sprachen sind J-A-J-I-Sprachen (Jochebed, Aaron, Jafet, Isaschar)

• Befehlende Sprachen sind wortreich und deterministisch und verwenden Register
• Befehlende Sprachen können lesbar oder unlesbar sein
• Befehlende Sprachen sind Abwandungen von langweiligen imperativen Programmiersprachen

".Getrude Stein" is a new programming language named after the writer (which
I happen to like). Actually, its less of a language and more of a language
encoding.

The idea is simple: the code consists of regular sentences of any kind of
natural language. For each sentence, an average word length is calculated
(and rounded up/down). Words that are exactly as long as the average word
are ignored. For the other words, a ratio [words longer than average]/[words
smaller than average] is calculated and used as an instruction index. (For
instance, the ratio 4/1 could be the add instruction and so on). Sentences
that contain ! or ? are ignored and can be used as comments. Numbers are
encoded as ratios of the form 1/x , then decoded as (int)(1/(1/x)).

I think programming in this encoding should be *quite* difficult, because
you have the "unenforced" restriction that the sentences should be proper
english (or German, or Swaheli or whatever) sentences. [So, cheating aka
using "xxx" as word is not allowed]. Maybe one can enforce as restriction
some language heuristics (e.g. not too many of the same character in one
word etc.]

"Hello World

Subject: [.Gertrude] [Long] Hello, World
Date: Sat, 5 May 2001 11:04:01 +0100

The following is a -working- version of "Hello, World" in .Gertrude. All sentences are taken either from the 1914 text "Tender Buttons" by Gertrude Stein, available online at http://www.bartleby.com/140/1.html, or from Kants Critique of Pure Reason. The interpreter for this fine sourcecode will be available for downloading on my site tomorrow. I'm looking for great online texts to turn into .gertrude sourcecode, so if you have suggestions, shoot.

It shows what use there is in a whole piece if one uses it and it is extreme

 Romeo, a young man with a remarkable patience.
 Juliet, a likewise young woman of remarkable grace.
 Ophelia, a remarkable woman much in dispute with Hamlet.
 Hamlet, the flatterer of Andersen Insulting A/S.


                     Act I: Hamlet’s insults and flattery.

                     Scene I: The insulting of Romeo.

 [Enter Hamlet and Romeo]

 Hamlet:
  You lying stupid fatherless big smelly half-witted coward!
  You are as stupid as the difference between a handsome rich brave
  hero and thyself! Speak your mind!

  You are as brave as the sum of your fat little stuffed misused dusty
  old rotten codpiece and a beautiful fair warm peaceful sunny summer’s
  day. You are as healthy as the difference between the sum of the
  sweetest reddest rose and my father and yourself! Speak your mind!

  You are as cowardly as the sum of yourself and the difference
  between a big mighty proud kingdom and a horse. Speak your mind.

  Speak your mind!

 [Exit Romeo]

                     Scene II: The praising of Juliet.

 [Enter Juliet]

 Hamlet:
  Thou art as sweet as the sum of the sum of Romeo and his horse and his
  black cat! Speak thy mind!

 [Exit Juliet]

                     Scene III: The praising of Ophelia.

 [Enter Ophelia]

 Hamlet:
  Thou art as lovely as the product of a large rural town and my amazing
  bottomless embroidered purse. Speak thy mind!

  Thou art as loving as the product of the bluest clearest sweetest sky
  and the sum of a squirrel and a white horse. Thou art as beautiful as
  the difference between Juliet and thyself. Speak thy mind!

 [Exeunt Ophelia and Hamlet]


                     Act II: Behind Hamlet’s back.

                     Scene I: Romeo and Juliet’s conversation.

 [Enter Romeo and Juliet]

 Romeo:
  Speak your mind. You are as worried as the sum of yourself and the
  difference between my small smooth hamster and my nose. Speak your
  mind!

 Juliet:
  Speak YOUR mind! You are as bad as Hamlet! You are as small as the
  difference between the square of the difference between my little pony

  codpiece. Speak your mind!

 [Exit Romeo]

Mehrdimensionale Sprachen

• Mehrdimensionale Sprachen sind H-M-H-I-Sprachen (Heftzibah, Mose, Ham, Isaschar)
• Mehrdimensionale Sprachen sind un-wortreich, un-lesbar und deterministisch
• Sie benutzen einen Stack zur Speicherung von Werten
• Ein Programmzeiger startet in der linken oberen Ecke, die Richtung ändert sich während des Programmes

Bsp.: PIET

Erfunden von:

• David Morgan-Mar (<= 2002)

Designkriterien:

• Programme sollen aussehen wie abstrakte Kunst
• Besonders schöne Programme sehen aus wie Bilder von Piet Mondrian

Es existieren:

• Interpreter
• Piet-Editor mit Traces
• Online Piet Editor und Compiler (Demo)

Die kleinste semantische Einheit in einer solchen Bilddatei ist ein „Codel“ (Zusammensetzung von „Code“ und „Pixel“), ein – in der visuellen Repräsentation als Bild – Quadrat aus n2 Pixeln gleicher Farbe. Dieser Wert n wird dem Piet-Interpreter als Parameter übergeben und für die visuelle Darstellung von Piet-Programmen so gewählt, dass ein optisch ansprechendes (nicht zu kleines) Bild resultiert. Bei den Beispielen rechts hat n den Wert 4 (oben) beziehungsweise 11 (unten).

Technisch muss der Programmcode in Form einer Bilddatei im GIF-Format vorliegen. Piet ist eine Interpretersprache, das heißt der Piet-Interpreter liest den Inhalt der Datei (hier einer Bilddatei) mit dem Quelltext bitweise ein und interpretiert die darin enthaltenen Informationen als Programmbefehle.

Syntax

• Piet ist eine grafische Programmiersprache
• Zwei Programmzeiger bewegen sich durch das Bild und werden durch Farbübergänge gedreht
• Es gibt einen Stack, auf den Werte gepusht werden können
• Die Zahl der Codels ("Code + Pixel") in einer zusammenhängenden Farbfläche repräsentiert einen Integer
• Der Übergang von einer Farbe zur nächsten triggert eine Anweisung
• Schwarze Felder können nicht betreten werden, der Programmzeiger bleibt hängen und wählt eine andere Richtung
• Durch weiße Farbfelder gleitet der Programmzeiger ohne Veränderung

• Hue Cycle: red → yellow → green → cyan → blue → magenta → red
• Lightness Cycle: light → normal → dark → light
