Biscuit Programming Language (BL)

The Biscuit Language (BL) is simple imperative programming language using LLVM backend implemented in C. Language syntax and all it's features are still in development and not ready for real use yet. Biscuit is designed to be simple, fast and explicit. Language syntax is inspired by JAI.

Motivation: I'm enjoying programming in C, but I miss some features there, on the other side C++ seems to be too much complicated for me and language itself require sometimes more attention than solved problem. So I decided to create my own language with all features I need and which I considered useful.

Goals:

manual memory management
pointers
no exceptions
fast compilation
full compile-time execution (integrated interpreter)
no OOP
types as values in compile-time
use of the LLVM backend
multiplatform

Example program:

#load "std/file.bl"

main :: fn () s32 {
    file := file_open(#file);
    defer file_close(file);

    content := file_read_all(file);
    defer mem_free(auto content.ptr);
    print("%\n", content);

    return 0;
};

main :: fn () s32 { file := file_open(#file); defer file_close(file);

content := file_read_all(file);
defer mem_free(auto content.ptr);
print("%\n", content);

return 0;

}; [/code]

Compile time execution:

$blc -r test.bl
Compiler version: 0.5.1 (pre-alpha)
Target: x86_64-apple-darwin17.7.0
Compile assembly: test

Executing 'main' in compile time...
#load "std/file.bl"

main :: fn () s32 {
    file := file_open(#file);
    defer file_close(file);

    content := file_read_all(file);
    defer mem_free(auto content.ptr);
    print("%\n", content);

    return 0;
};

Execution finished with state: 0

Running native linker...
Compiled 1355 lines in 0.258531 seconds.

What is done:

Language basic features
Some documentation
DWARF debug symbol generation
Compile time execution
Static RTTI generation
Experimental wrappers for SDL2, SDL2_Image and Vulkan API
Two demo projects included in repository

What is planned to do:

Explicit compile time executed calls
Better error messages
Full documentation
Lot of bug-fixes
Use multiple cores for lexing and parsing
Better handling of invalid syntax in parser
Speed optimizations of the compiler
Support of multithreading in interpreter
Create bigger "real" project using this language to validate functionality and feature set
