GolfScript is an esoteric programming language that is stack-based and designed to allow programs to be written in as few keystrokes as possible. It aims to be simple and easy to write.[1] The design of the language makes it easy to use in code golfing contests.
History
GolfScript was released on 13 December 2007 and added to the golf server run by Shinichiro Hamaji the next day.[1] The GolfScript specification was originally implemented in Ruby by Darren Smith.[2] A Perl implementation was released by Marty O' Brien on 11 July 2011.[3]
Language
Programs in GolfScript consist of lists of items, each of which is pushed onto the stack as it is encountered with the exception of variables which have code blocks as their value, in which case the code is executed. When a variable assignment (carried out through the placement of a colon before the name of the variable) is encountered, the top item on the stack is popped and assigned to the variable.[4]
GolfScript attempts to reach its goal of solving problems in as few keystrokes as possible through the use of single symbols to represent high-level operations.[1] A single symbol can stand for multiple operations depending on the type of the arguments passed to it.[4]
Input and output
If input is supplied to a GolfScript program, it is pushed onto the stack as a string before the program is executed. Output is provided via the stack's contents being printed when execution of the program finishes.[4]
Examples
Hello world
The traditional Hello world program can be written in GolfScript as:[5]
"Hello World!"
This program has only one item, the string "Hello World!", which is pushed onto the stack and then printed at the end of the program.
Other examples
A program to get two numbers from standard input, add them together, and print the result can be written in GolfScript as:[6]
n%'+'*'"#{
}"'n/\*~
