Language Documentation

A rick roll oriented, dynamic, strong, interpreting esoteric programming language.

Notice:

The syntax of RickRoll-Lang is not same as Python

1. It doesn't need indentation
2. The code must be written inside the main method, otherwise the interpreter will not execute

Commands to execute your code

I usually execute my source code like this:

python3 rickroll.py -r [Source Code File Name]

If you want to know the execution time:

python3 rickroll.py -r [Source Code File Name] --time

The interpreter can generate a .mp3 file from your source code (This feature is not completed yet)

python3 rickroll.py -r [Source Code File Name] -audio [Audio_File_Name]

Also the interpreter provides you to "sing" code (This feature is not completed yet)

python3 rickroll.py -sing [MP3 File Name] [Source Code(Text) File Name]

Hello World

take_me_to_ur_heart                                                      # This is the MAIN METHOD
    give_u_up msg = "Never gonna give you up, never gonna let you down~" # Define a variable
    i_just_wanna_tell_u_how_im_feeling msg                               # print the "msg" variable
say_good_bye                                                             # End the main method

And you can get the output on your terminal:

Never gonna give you up, never gonna let you down~

Defining Variable

You can define int, float, string, list/array, set, and tuple.

give_u_up a = 10~
give_u_up b = "It is a string"
give_u_up c = ["This", "is", "an", "array"]

If Statement

Indentation in RickRoll-lang is optional.

take_me_to_ur_heart~    # You can add "~" at the end of the statement (it is totally optional)
    give_u_up a = 10

    and_if_u_ask_me_how_im_feeling a is 10
        i_just_wanna_tell_u_how_im_feeling "A is 10!"
    say_good_bye

say_good_bye~

Equivalent to Python:

if __name__ == '__main__':
    a = 10
    if a == 10:
        print("A is 10!")

And you will get this on your terminal

"A is 10!"

Loop

take_me_to_ur_heart
    together_forever_and_never_to_part # Endless loop

    say_good_bye

say_good_bye

Equivalent to Python:

if __name__ == "__main__":
    while True:
        pass

Defining Function

never_knew func arg1, arg2 could_feel_this_way  # Define a function
    when_i_give_my arg1, arg2 it_will_be_completely # Return arg1 and arg2
say_good_bye

Equivalent to Python:

def func(arg1, arg2):
    return arg1, arg2
