Publicado<\/a><\/noindex> lanzamiento del motor JavaScript Duktape 2.4.0<\/a><\/noindex>, orientado a la integraci\u00f3n en la base de c\u00f3digo de proyectos en C\/C++. El motor se distingue por su tama\u00f1o compacto, alta portabilidad y bajo consumo de recursos. Los c\u00f3digos fuente del motor est\u00e1n escritos en C y se distribuyen<\/a><\/noindex> bajo licencia MIT. <\/p>\n

El c\u00f3digo de Duktape ocupa alrededor de 160 kB y consume solo 70 kB de RAM, y en modo de bajo consumo de memoria 27 kB de RAM. Para integrar Duktape en c\u00f3digo C\/C++, hay suficiente<\/a><\/noindex> se deben incluir en el proyecto los archivos duktape.c y duktape.h, y utilizar la API de Duktape<\/a><\/noindex> para invocar funciones en JavaScript desde c\u00f3digo C\/C++ o viceversa. Para liberar objetos no utilizados de la memoria, se utiliza un recolector de basura con finalizador, basado en una combinaci\u00f3n de algoritmo<\/a><\/noindex> de conteo de referencias con el algoritmo de marcado y barrido (Mark and Sweep). El motor se utiliza para procesar JavaScript en el navegador NetSurf<\/a><\/noindex>.<\/p>\n

Se garantiza la compatibilidad total con las especificaciones Ecmascript 5.1 y parcial soporte<\/a><\/noindex> Ecmascript 2015 y 2016 (E6 y E7), incluyendo soporte para el objeto Proxy para la virtualizaci\u00f3n de propiedades, arreglos tipados, ArrayBuffer, Node.js Buffer, Encoding API, objeto Symbol, etc. Tambi\u00e9n incluye un depurador integrado, motor para ejecutar expresiones regulares y subsistema para soporte de Unicode. Adem\u00e1s, se proporcionan extensiones espec\u00edficas, como soporte para corrutinas, marco integrado para registro y mecanismo de carga de m\u00f3dulos basado en CommonJS, sistema de cach\u00e9 de bytecode que permite guardar y cargar funciones compiladas.<\/p>\n

En esta nueva versi\u00f3n se han implementado<\/a><\/noindex> nuevas llamadas a duk_to_stacktrace() y duk_safe_to_stacktrace() para obtener trazas de pila, duk_push_bare_array() para agregar instancias independientes de arreglos. Se han traducido al p\u00fablico las funciones duk_require_constructable() y duk_require_constructor_call(). Se ha mejorado la compatibilidad con la especificaci\u00f3n ES2017. Se ha optimizado el trabajo con arreglos y objetos. Se ha a\u00f1adido la opci\u00f3n «—no-auto-complete» a la interfaz CLI de duk para desactivar la autocompletaci\u00f3n de entradas.<\/p>\n
