Delus

pypi project : https://pypi.org/project/delus/

A set of super lightweight, zero-dependency code generators and compilers written in pure Python. It provides automated context managers (with scopes) to generate clean, highly-optimized C and Assembly code without the overhead of heavy Abstract Syntax Trees (AST).

Why this exists?

Traditional decompilers and transpilers rely on massive AST parsing trees and external dependencies (like LLVM). This project implements an elegant, pure Python Builder Pattern that tracks register allocations and memory states directly via Python's __enter__ and __exit__ magic methods. It generates fast, naked, and obfuscated-ready outputs.

Contribution & Development

This is a hacker-centric project. We welcome and encourage anyone to contribute to this repository. You are completely free to submit a Pull Request with a brand new code architecture, or suggest refactoring and optimizations for the existing codebase.

Quick Examples

1. C Generation Example

if __name__ == "__main__":
    program = Mylang()
    program.add_lib("cstdio")

    with program.function(program, "main", "int") as main:
        with main.for_loop("int i = 0", "i<10", "i++"):
            with main.if_condintion("i % 2 == 0"):
                main.print("i", variable=True)
        main.return_val("0")
        
    print(program.run())

2. Assembly Generation Example

if __name__ == "__main__":
    mylan = mylang()
    mylan.create_func("counter")
    mylan.create_func("out")
    mylan.create_func("check")
    
    mylan.sys_exit(0, "out")
    mylan.print("hello world", "counter")
    mylan.newline("counter")
    mylan.decrease("r10", "counter")
    mylan.mov("r10", "10", "_start")
    mylan.jmp("check", "_start")
    mylan.cmp("r10", "0", jmp_if_equal="out", jmp_if_not_equal="counter", func="check")
    mylan.jmp("check", "counter")
    
    print(mylan.run())
