I Made a Programming Language with Python Syntax, zero-copy and C-Speed

In plain words

This is a programming language built with Python syntax that aims for zero-copy memory management and C-level performance. It is designed for developers who want Python's familiar syntax without sacrificing speed or memory efficiency. The language is available on GitHub for review and contribution.

From the sources

def main(): x = 2 y = 3 print("Hello from Mantis") Mantis 7 is a minimal, deterministic, zero‑copy compiler toolchain. It takes Mantis source code (.mt), compiles it into portable bytecode (.mtn), translates that bytecode into native machine code (x86‑64 or ARM64), embeds a position‑independent string runtime, and executes it directly from RWX memory. .mt — Mantis source file .mtn — Single‑module bytecode file .mtnb — Multi‑module bundle (MTNB format) Contains modules + assets + offsets -1 → print(...) (not yet mapped natively) -2 → concat(a, b) → __mantis_string_concat -3 → to_string(i64) → __mantis_format_i64 Backends resolve these using runtime offsets provided by build(). python cli.py…from github.com

  Micro-mitten – Research language with compile-time memory management2020 · github.com · ▲236

  I've been working on implementing the compile-time approach to memory management described in this thesis (https://www.cl.cam.ac.uk/techreports/UCAM-CL-TR-908.pdf) for some time now - some of the performance results look promising! (Although some less so...) I think it would be great to see this taken further and built into a more complete functional language.

  Going into freshman year, figured I should build an interpreter2023 · ▲138

  Hi all! I'm going into my freshman year, and figured that the best way to prepare for the intro to programming Racket course would be to implement my own garbage-collected, dynamically typed, functional programming language in C ;) Anyways... here's the repo: https://github.com/liam-ilan/crumb I started learning C over the summer, so I still have a whole lot to learn... Any feedback would be greatly appreciated! :D

  Copy-and-patch compiler for hard real-time PythonFeb 2026 · github.com · ▲65

  I built Copapy as an experiment: Can Python be used for hard real-time systems? Instead of an interpreter or JIT, Copapy builds a computation graph by tracing Python code and uses a custom copy-and-patch compiler. The result is very fast native code with no GC, no syscalls, and no memory allocations at runtime. The copy-and-patch compiler currently supports x86_64 as well as 32- and 64-bit ARM. It comes as small Python package with no other dependencies - no cross-compiler, nothing except Python. The current focus is on robotics and control systems in general. This project is early but…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
