An esoteric language/compiler written with Rust and Rust LLVM bindings

MeidoLang (メイドラング)

A not so useful and esoteric language.

The goal of this project was to contain some quirky or novel syntax in a stack-style programming language. The behavior of this language borrows heavily from a language I briefly looked into called gforth.

The language is not turing-complete, and therefore is not likely useful for any real-world task. Operations supported include:

• "+"
• "-"
• "*"
• "/"
• Printing the stack
• Printing the string

The grammar as I understand it (Hopefully I understand it. It is my language after all.) looks like this:

program: expList PROGRAMEND
    ;

expList: exp expList 
    | exp
    ;
    
exp:
    value FINALIZER
    | exp exp PLUS
    | exp exp MINUS
    | exp exp MULT
    | exp exp DIV
    | PRINTSTACK
    |  STRINGSTART STRINGLITERAL STRINGEND
    ;

value: value ONE 
    | ONE
    ;

The language utilizes llvm through the inkwell wrapper of the rust bindings. If you have been struggling to learn how to use it, hopefully this code is useful to you!

Note: If you are trying to use this language, although I have not tested it, I would recommend you have a C compiler lying around, presuming then you've also got those libraries around as well. The print code makes use of printf, so I would imagine having C installed on your system would be important.
