Opublikowano<\/a><\/noindex> Wydanie silnika JavaScript Duktape 2.4.0<\/a><\/noindex>, zaprojektowanego z my\u015bl\u0105 o integracji w kodzie projekt\u00f3w w j\u0119zyku C\/C++. Silnik wyr\u00f3\u017cnia si\u0119 kompaktowymi rozmiarami, wysok\u0105 przeno\u015bno\u015bci\u0105 i niskim zu\u017cyciem zasob\u00f3w. Kod \u017ar\u00f3d\u0142owy silnika napisany jest w j\u0119zyku C i s\u0105 rozpowszechniane<\/a><\/noindex> na licencji MIT. <\/p>\n

Kod Duktape zajmuje oko\u0142o 160 kB i zu\u017cywa zaledwie 70 kB RAM, a w trybie niskiego zu\u017cycia pami\u0119ci 27 kB RAM. Aby zintegrowa\u0107 Duktape z kodem w C\/C++ wystarczy<\/a><\/noindex> nale\u017cy doda\u0107 do projektu pliki duktape.c oraz duktape.h i u\u017cywa\u0107 API Duktape<\/a><\/noindex> do wywo\u0142ywania funkcji JavaScript z kodu C\/C++ lub odwrotnie. Aby zwolni\u0107 nieu\u017cywane obiekty z pami\u0119ci, stosuje si\u0119 zbieracz \u015bmieci z finizatorem, oparty na kombinacji algorytmu<\/a><\/noindex> liczenia referencji z algorytmem znacznik\u00f3w (Mark and Sweep). Silnik jest stosowany do przetwarzania JavaScript w przegl\u0105darce NetSurf<\/a><\/noindex>.<\/p>\n

Zapewnia pe\u0142n\u0105 zgodno\u015b\u0107 ze specyfikacjami Ecmascript 5.1 oraz cz\u0119\u015bciow\u0105 wsparcie<\/a><\/noindex> Ecmascript 2015 i 2016 (E6 i E7), w tym wsparcie dla obiektu Proxy do wirtualizacji w\u0142a\u015bciwo\u015bci, typizowane tablice, ArrayBuffer, Node.js Buffer, Encoding API, obiekt Symbol itp. Zawiera wbudowany debugger, silnik do wykonywania wyra\u017ce\u0144 regularnych oraz podsystem wsparcia Unicode. Oferuje r\u00f3wnie\u017c specyficzne rozszerzenia, takie jak wsparcie dla korutyn, wbudowany framework do logowania, mechanizm \u0142adowania modu\u0142\u00f3w oparty na CommonJS oraz system cache'owania kodu bajtowego, pozwalaj\u0105cy na zapis i \u0142adowanie skompilowanych funkcji.<\/p>\n

W nowym wydaniu wdro\u017cono<\/a><\/noindex> Nowe wywo\u0142ania duk_to_stacktrace() i duk_safe_to_stacktrace() do uzyskiwania \u015blad\u00f3w stosu, duk_push_bare_array() do dodawania niezale\u017cnych instancji tablic. Do publicznych przeniesiono funkcje duk_require_constructable() i duk_require_constructor_call(). Ulepszona kompatybilno\u015b\u0107 z specyfikacj\u0105 ES2017. Zoptymalizowano dzia\u0142anie z tablicami i obiektami. W interfejsie CLI duk dodano opcj\u0119 «—no-auto-complete» do wy\u0142\u0105czenia automatycznego uzupe\u0142niania wej\u015bcia.<\/p>\n
