StupidStackLanguage

StupidStackLanguage (SSL) is an esoteric programming language in which all operations are performed on a stack. Created by Lebster, SSL is case-insensitive and uses the characters A-Z to define its set of operations, with each character corresponding to a specific stack manipulation or input/output function. The language is designed for exploring stack-based computation and unconventional programming paradigms.

In SSL, only numbers can be stored on the stack, and the operations include pushing and popping values, arithmetic operations such as addition, subtraction, multiplication, division, incrementing and decrementing values, as well as stack manipulation commands like swapping items, duplicating the top value, and deleting the entire stack. SSL also includes input and output instructions, such as reading numbers or characters from the user and printing values either as ASCII characters or numbers. Control flow is handled using paired commands that allow for conditional skipping and looping based on the stack's top value. The language provides examples for a variety of classic programming problems, including "Hello World", the cat program, addition, truth-machine, factorial calculation, calculator, Fibonacci sequence, printing a box of characters, and the Ackermann function.

SSL can be used through an online interpreter available on a website, which executes programs at a slower pace compared to the Python interpreter. There is also a Python-based implementation of the language, which can be run from the command line by providing a filename containing SSL code. The Python interpreter processes SSL source code by removing comments and non-alphabetic characters, then executing the corresponding stack operations as defined by the language specification.

The tool is primarily intended for language enthusiasts and those interested in esoteric programming languages or experimenting with stack-based computation.
