Hy
Hy es una implementación de Lisp para Python que permite escribir sintaxis Lisp que se compila a bytecode de Python. Opera como un dialecto de Lisp basado en Python y lenguaje de S-expressions, proporcionando acceso completo a la librería estándar y al ecosistema de Python.
El lenguaje se centra en la metaprogramación basada en macros, presentando un sistema de macros que recorre el AST y macros de lectura que permiten transformaciones de sintaxis personalizadas y reglas de análisis. Permite la manipulación del árbol de sintaxis abstracta para extender las capacidades del lenguaje.
El proyecto incluye un bucle de lectura-evaluación-impresión (REPL) para desarrollo interactivo y admite la ejecución de scripts independientes. Cubre capacidades de programación funcional como la coincidencia de patrones estructurales y el desarrollo de programas asíncronos usando construcciones async y await.
El código fuente puede traducirse a archivos fuente de Python equivalentes para inspección o distribución.
Features
