history

Project history and usage

Hy is a Lisp dialect embedded in Python. It reads Lisp syntax and transforms it into Python abstract syntax tree objects, giving users macros and Lisp syntax while keeping access to Python built-ins, libraries, packaging, and runtime behavior.

Project history

The public repository was created in December 2012. Hy's README frames the project with the line that Lisp and Python should love each other, and explains the core technical idea: Hy code becomes Python AST, so Python's ecosystem remains available.

The 1.0.0 announcement in September 2024 described that release as arriving after nearly 12 years of on-and-off development and real-world use. The NEWS file states that Hy follows semantic versioning since 1.0.0, marking a stabilization point after the long 0.x period.

Adoption history

Hy is distributed through Python packaging and also appears in system package managers such as Homebrew, Debian, Ubuntu, Arch, Alpine, and Nix. Its community surfaces include GitHub Discussions, Stack Overflow's `hy` tag, documentation on hylang.org, and a browser console for trying the language.

How it is used

Users run `hy` for a REPL, execute `.hy` programs with `hy myprogram.hy`, translate with `hy2py`, and compile with `hyc`. The homepage examples show Python-equivalent forms for assignment, sorting, functions, context managers, comprehensions, and macros.

Why package nerds care

Hy is interesting to package nerds because it is not a separate virtual machine or runtime island. It packages as a Python-hosted language that can import Python modules directly, which makes it easier to install experimentally while still offering Lisp macros and syntax.

Timeline

  • 2012: Public GitHub repository created.
  • 2024: 1.0.0 released after nearly 12 years of development.
  • 2024: NEWS states semantic versioning begins with 1.0.0.
  • 2026: 1.3.0 release notes list support for Python 3.9 through Python 3.15.

Related projects

  • Hy is related to Python, Lisp-family languages, macro systems, Python AST tooling, PyPI packaging, and editor/REPL workflows for experimental languages.

Sources

  • Hy homepage, README, NEWS, 1.0.0 announcement, repository metadata, and Homebrew package metadata were used.
