Publi\u00e9<\/a><\/noindex> Lancement du moteur JavaScript Duktape 2.4.0<\/a><\/noindex>, con\u00e7u pour \u00eatre int\u00e9gr\u00e9 dans le code de base de projets en C\/C++. Le moteur se distingue par sa taille compacte, sa grande portabilit\u00e9 et sa faible consommation de ressources. Le code source du moteur est \u00e9crit en C et sont distribu\u00e9s<\/a><\/noindex> sous licence MIT. <\/p>\n

Le code de Duktape occupe environ 160 kB et consomme seulement 70 kB de RAM, et en mode faible consommation de m\u00e9moire, 27 kB de RAM. Pour int\u00e9grer Duktape dans le code C\/C++ sont suffisants<\/a><\/noindex> ajoutez les fichiers duktape.c et duktape.h \u00e0 votre projet, et utilisez Duktape API<\/a><\/noindex> pour appeler des fonctions JavaScript depuis le code C\/C++ ou vice versa. Un ramasse-miettes avec finaliseur est utilis\u00e9 pour lib\u00e9rer les objets inutilis\u00e9s en m\u00e9moire, bas\u00e9 sur une combinaison de l'algorithme<\/a><\/noindex> de comptage des r\u00e9f\u00e9rences et de l'algorithme de marquage et balayage (Mark and Sweep). Le moteur est utilis\u00e9 pour ex\u00e9cuter JavaScript dans le navigateur NetSurf<\/a><\/noindex>.<\/p>\n

Il assure une compatibilit\u00e9 compl\u00e8te avec les sp\u00e9cifications Ecmascript 5.1 et partielle avec la prise en charge<\/a><\/noindex> Ecmascript 2015 et 2016 (E6 et E7), y compris le support de l'objet Proxy pour la virtualisation des propri\u00e9t\u00e9s, des tableaux typ\u00e9s, ArrayBuffer, Node.js Buffer, l'API d'encodage, l'objet Symbol, etc. Il comprend un d\u00e9bogueur int\u00e9gr\u00e9, un moteur pour l'ex\u00e9cution d'expressions r\u00e9guli\u00e8res et un sous-syst\u00e8me pour le support de l'Unicode. Des extensions sp\u00e9cifiques sont \u00e9galement fournies, telles que le support des coroutines, un cadre int\u00e9gr\u00e9 pour la journalisation, un m\u00e9canisme de chargement de modules bas\u00e9 sur CommonJS, et un syst\u00e8me de mise en cache de bytecode permettant de sauvegarder et charger des fonctions compil\u00e9es.<\/p>\n

Dans cette nouvelle version sont impl\u00e9ment\u00e9s<\/a><\/noindex> nouvelles fonctions duk_to_stacktrace() et duk_safe_to_stacktrace() pour obtenir des traces de pile, duk_push_bare_array() pour ajouter des instances de tableaux ind\u00e9pendants. Les fonctions duk_require_constructable() et duk_require_constructor_call() ont \u00e9t\u00e9 traduites en public. Am\u00e9lioration de la compatibilit\u00e9 avec la sp\u00e9cification ES2017. Optimisation de la gestion des tableaux et des objets. Dans l'interface CLI de duk, une option «—no-auto-complete» a \u00e9t\u00e9 ajout\u00e9e pour d\u00e9sactiver la compl\u00e9tion automatique de l'entr\u00e9e.<\/p>\n
