Compy

About

Compy is a very small transpiler that takes Python-looking code and turns it into plain C.

It produces readable output, adds no runtime, and supports dropping real C code with __inline_c__ and __inline_c_global__ blocks.

What it understands

• def name(args): → int name(args) {
• if cond: / else:
• return value
• print(expr) → printf(…) with basic type guessing
• fprint_str("text ${x}") / fprint_int() / fprint_flt()
• Short type names: int, flt, str, bool, char, double
• include stdio.h or include "file.h"
• Indent-based blocks (automatically adds/closes braces)
• Raw C inside __inline_c__ {…} blocks
• Global raw C with __inline_c_global__ {…}

Compy stdlib (included when you use it)

• pow_int(base, exp)
• sqrt_flt(x)
• abs_int(x)
• len_str(s)
• concat(a, b) → new allocated string
• substr(s, start, len) → new allocated string
• seed_rand() / rand_int(min,max) / rand_flt(min,max)
• input_str(buf, maxlen, prompt)
• input_int(prompt) / input_flt(prompt)
• write_file(path, content)
• read_file(path) → allocated string or NULL

Quick usage

1. Write code in .cmpy file
2. Run: ./compy yourfile.cmpy
3. Compile generated file: gcc out.c -O3 -o program
4. Run: ./program

Output always goes to out.c in current directory.
Compiler itself is tiny (~400 LOC).
