Avaldatud<\/a><\/noindex> JavaScript-mootori v\u00e4ljalaskmine Duktape 2.4.0<\/a><\/noindex>, mis on suunatud C\/C++ projekti koodibaasi integreerimisele. Mootor on kompaktne, k\u00f5rgelt \u00fclekantav ja madala ressursikasutusega. Mootori allikakood on kirjutatud C keeles ja levitatakse<\/a><\/noindex> MIT litsentsi alusel. <\/p>\n

Duktape kood v\u00f5tab umbes 160 kB ja kasutab ainult 70 kB RAM-i, madala m\u00e4lu tarbimise re\u017eiimis aga 27 kB RAM-i. Duktape'i integreerimiseks C\/C++ koodi piisab<\/a><\/noindex> projektis duktape.c ja duktape.h failide lisamisest ning Duktape API<\/a><\/noindex> kasutamisest JavaScripti funktsioonide kutsumiseks C\/C++ koodist v\u00f5i vastupidi. M\u00e4lus kasutamata objektide vabastamiseks rakendatakse kokkuv\u00f5ttega pr\u00fcgikoristajat, mis p\u00f5hineb kombinatsioonil algoritmist<\/a><\/noindex> viidete lugemise ja m\u00e4rgpuhastus (Mark and Sweep) algoritmist. Mootorit kasutatakse JavaScripti t\u00f6\u00f6tlemiseks brauseris NetSurf<\/a><\/noindex>.<\/p>\n

Tagatakse t\u00e4ielik \u00fchilduvus Ecmascript 5.1 spetsiifikatsioonidega ja osaline toetamine<\/a><\/noindex> Ecmascript 2015 ja 2016 (E6 ja E7), sealhulgas Proxy objekti tugi omaduste virtualiseerimiseks, t\u00fc\u00fcpide massiivid, ArrayBuffer, Node.js Buffer, Encoding API, Symbol objekt jne. Komplektil on sisseehitatud t\u00f5rkefinder, regulaaravaldiste t\u00f6\u00f6tlemise mootori ja Unicode'i toetas\u00fcsteem. Samuti pakutakse spetsiifilisi laiendusi, nagu n\u00e4iteks kooperatiivide tugi, sisseehitatud logimise raamistik, CommonJS-p\u00f5hine moodulite laadimise mehhanism ja s\u00fcmbioosi salvestamise s\u00fcsteem, mis v\u00f5imaldab salvestada ja laadida kompileeritud funktsioone.<\/p>\n

Uues v\u00e4ljaandes on ellu viidud<\/a><\/noindex> uued duk_to_stacktrace() ja duk_safe_to_stacktrace() kutsed stektrassi saamiseks, duk_push_bare_array() s\u00f5ltumatute massiivide eksemplaride lisamiseks. Avalikuks on saanud funktsioonid duk_require_constructable() ja duk_require_constructor_call(). Parandatud on \u00fchilduvus ES2017 spetsifikatsiooniga. Massiivide ja objektidega t\u00f6\u00f6tamine on optimeeritud. CLI-interfaci duk on lisatud valik «—no-auto-complete» sisestamise automaatsete t\u00e4ienduste v\u00e4ljal\u00fclitamiseks.<\/p>\n
