Hy (alternately, Hylang) is a dialect of the Lisp programming language designed to interoperate with Python by translating expressions into Python's abstract syntax tree (AST). Similar to Clojure's mapping of s-expressions onto the JVM[1], Hy is meant to operate as a transparent Lisp front end to Python's abstract syntax.[2] Hy also allows for Python libraries (including the standard libraries) to be imported and accessed alongside Hy code with a compilation[note 1] step converting the data structure of both into Python's AST.[3][4]

Because Lisp allows for programming on the language, Hy can be used to write domain-specific languages.[5]

Hy is compatible with Python 2.6 to 3.4 and multiple Python interpreters (e.g. PyPy).[4] Hy was introduced at PyCon 2013 by Paul Tagliamonte. [6]

Notes

  1. ^ "Compiled" is a term which may apply to expressing Hy code in Pythons AST or converting that AST into bytecode.
