language_name: DRAMAQUEEN

notes_from_prof: |
    Language designed by Austin Benigni.
    This is a fun and silly-looking language, but it seriously works!
    Some aspects follow a similar structure to languages you are used to
    like Python, but with different operators and keywords.
    The string literal syntax is pretty clever - notice how it allows us
    to completely avoid the need for escapes.


example_program: |
    shhh This is a simple program in the DRAMA QUEEN language shhh
    shhh HEAR_YE() serves as a call to print the enclosed expression shhh
    shhh The spaces just inside the ~'s are required, and do not go into the string itself shhh
    HEAR_YE(~ I am a DRAMATIC LANGUAGE ~) shhh I NEED MY SPACE! shhh

    HEAR_YE(REVERTERE(GIVE_ME))
    shhh GIVE_ME takes a single line of text from the console as a string.
         REVERTERE reverses a string given to it shhh

    shhh In order to concatenate strings you use the UNIFY operator as shown below shhh
    HEAR_YE(~ I will be as DRAMATIC ~ UNIFY ~   ~ UNIFY ~ as I WANT ~)

    shhh Should you like to print a ~, all you have to do is join
         any combination of capital letters to the opening tilde as well as the ending tilde.
         Now any tilde on the inside can be printed shhh
    HEAR_YE(~APPLE I'd like to print a ~ thank you very much. ~APPLE)

example_input_1: |
    hello

example_output_1: |
    I am a DRAMATIC LANGUAGE
    olleh
    I will be as DRAMATIC as I WANT
    I'd like to print a ~ thank you very much.

example_input_2: |
    That seems like a bit much

example_output_2: |
    I am a DRAMATIC LANGUAGE
    hcum tib a ekil smees tahT
    I will be as DRAMATIC as I WANT
    I'd like to print a ~ thank you very much.


language_syntax: |
    statements:
        Print: HEAR_YE(expr)

    expressions:
        String Literal:
            A sequence of ASCII characters enclosed by a left and right delimiter.
            The left delimiter is a '~',
                followed by 0 or more uppercase letters (the magic word),
                followed by a single space.
            The right delimiter is a single space,
                followed by a '~',
                followed by the same magic word.

        Concatenation: expr1 UNIFY expr2

        Reversal: REVERTERE(expr)

        Input: GIVE_ME

    Comments: A comment can be opened by writing "shhh" and then closed
        just the same "shhh". If no closing "shhh" is provided, everything
        following the opening "shhh" will be commented out. Multiline and
        single line comments are both capable of being used with this
        format.

    Comments and whitespace are ignored everywhere except inside a
    string literal.


language_semantics: |
    Print: HEAR_YE() takes in a string and prints it out to the terminal

    String literal: The exact sequence of characters between (but not
        including) the opening and closing spaces of the delimiters,
        forms the string.

    Concatentaion: UNIFY operator takes two string literals and combines
        them together into one string.

    Reversal: REVERTERE() takes any string expression within parentheses
        and converts it to be completely reversed.

    Input: GIVE_ME can read in a singular line of text from the console
        as a string literal. Once the user hits the 'Enter' key what has
        been written gets read in.
