Compiler for a C/Go/Jai inspired language, written in C99.

This is a hobby project for fun, I don't expect people to write real code with it. This is the result of countless attempts to create a functioning compiler over the last four years, you can find my very first attempt here.

Right now it only compiles on Linux, because I'm developing it under Windows Subsystem for Linux version 2. Just run /build.sh and it will spit out an ELF executable called lang, providing you have gcc installed on your Linux system.

#import "std/basic.lang"

// Type inference, same as:
//    msg: string = get_message();
msg := get_message();

proc main() {
    print(msg.data);
}

proc get_message(): string {
    return "Hello, world\n";
}

I consider this project pre-alpha software, it has some bugs, but it mostly works. I'm working towards the basic feature set of the language being implemented robustly, then I will move onto real additions, right now it's basically a skin over C.

I am actively developing this project (as of September 2020), but here's some notes on the current progress:

• Currently outputting C code, this will change in the future.
• The bytecode interpreter for compile-time code execution is not currently working at all. It has been #if'd out for the time being while I redesign it.
• The lexer, parser, "resolver" (symbol resolution, expression-to-type evaluation, type inference) and checker (semantic and type checking) are fairly robust, though they most likely contain undiscovered bugs.

• /scratch: random files in the language itself which I use to test various aspects of the compiler, most of the code in here is nonsense and doesn't do anything lol.

• /demos: actual functioning code which serves some purpose.

• src/headers/: header files, this is where most of the types are declared.

• src/headers/stb: headers from the public-domain libraries by Sean Barrett.

• src/: actual C code, the file names should be self-explanatory, and each file has a comment describing what it contains at the very top.
