GRPH Programming Language

GRPH is my first attempt at creating a programming language. There have been multiple iterations of the language, with multiple versions: - The first version was interpreted and implemented in Java - The second version was rewritten in Swift but still interpreted - The final version is still in Swift, reusing the frontend of the previous version, but is now compiled using LLVM

The main usage of GRPH is for procedural graphics animations, though it can also be used for general-purpose programming.

Hello World

log: "Hello, World!"

Fizz Buzz

GRPH is indentation based, like Python.

#compiler indent spaces

#foreach n : range[0 100]
    #if n % 3 == 0 && n % 5 == 0
        log: "FizzBuzz"
    #elseif n % 3 == 0
        log: "Fizz"
    #elseif n % 5 == 0
        log: "Buzz"
    #else
        log: n

There are two ways to call functions and methods: - Instruction syntax: function: arg1 arg2 arg3 or method subject: arg1 arg2 arg3 - Expression syntax: function[arg1 arg2 arg3] or subject.method[arg1 arg2 arg3]

Expression syntax can also be used anywhere the instruction syntax is allowed, but when the return value is needed, expression syntax must be used.

Docker

GRPH can be installed using Docker:

docker run --rm -it --entrypoint /bin/bash snowy1803/grph
