The Shakespeare Programming Language (SPL) is an esoteric programming language created by Karl Hasselström and Jon Åslund in 2001. The design goal of Shakespeare was, according to the Manual, to make a language with beautiful source code that resembled Shakespeare plays.
Language Overview
Instructions are written as a play script, using characters as variables. Most variable manipulation is done through dialogue.
Title
Shakespeare starts with a title name (consisting of any character other than new line and .) and a ..
Example Title. (This is simply to specify what the program does, and nothing else.)
Introductions
You must then introduce characters, restricted to ones from Shakespeare plays, followed by a comma, description, and .. There must be at least one non-whitespace character in the description.
Romeo, a young man with a remarkable patience.
Acts
At least one act must be defined. Denoted as Act RomanNumeral: description. Act numbers start at one, and increment by for each new act.
Act I: The Murder of Juliet.
Scenes
Scenes are used as goto labels. At least one scene is required per act.
Scene I: description_goes_here..
Instructions
For all operations, "you" and all of "it's" forms are interchangeable with "thou" and "it's" forms, as long a proper grammar is maintained.
To be written, characters must first enter the stage. Use the format "[Enter Character]" or "[Enter Character and OtherCharacter]". A maximum of two characters can be on the stage at any one time. You can remove a character from the stage with "[Exit Character]" or remove all characters using "[Exeunt]".
By a character saying the following commands,
- "Speak your mind." - Outputs the ASCII character corresponding to the value held in the character being spoken to.
- "Open your heart." - Outputs the numeric value held in the character being spoken to.
- "Open your mind." - Inputs an ASCII character from the user and stores it in the character being spoken to.
- "Listen to your heart." - Inputs a number from the user and stores it in the character being spoken to.
To set which character is speaking, write:
Name:
Characters edit each other's values using dialogue. The general form is "You are" followed either by a character, constant expression, operation expression, or simile.
Constant expressions consist of a 'positive' (complementing) or 'negative' (insulting) noun, preceded by zero or more adjectives. A noun is equal to either 1 or -1, and each attached adjective doubles its value. A simile is written "as adjective as ", means nothing, and can be followed by a constant expression, character, or an operation expression. Operation expressions are written the operation of constant, operation, or character and constant, operation, or character.. Characters can be referenced using "yourself" or "thyself" if they are on stage, or by name if they aren't. For example:
[Enter Romeo and Juliet] Romeo: Thou art a vile coward! Open thy heart! Juliet: You are as lovely as the sum of Hamlet and a brave tree. Open thy heart.
Output:
-2>Hamlet+2<
Conditional statements are written something like this:
Scene II: The grand if greater than condition. [Enter Romeo and Juliet] Juliet: Am I better than you? Romeo: If so, let us proceed to scene I.
Scene II: The just as incredible if equal to condition. [Enter Romeo and Juliet] Juliet: Am I as good as you? Romeo: If so, let us proceed to scene I.
Computational class
As every Shakespeare program can be converted from a brainfuck program, (see here: https://github.com/mjdarby/Brain2Speare) Shakespeare is turing- complete. (More information needed)
