Guile kan worden gebruikt als een taal voor het ontwikkelen van extensies voor applicaties, het defini\u00ebren van configuraties of het ontwikkelen van componenten voor de interactie tussen verschillende primitieve elementen die door de applicatie worden aangeboden. Guile is de offici\u00eble extensietaal voor het besturingssysteem GNU. <\/p>\n<p>De basis van Guile is een effici\u00ebnte virtuele machine die een draagbare set instructies uitvoert, gegenereerd door een speciale optimaliserende compiler. De Guile-virtuele machine kan eenvoudig worden ge\u00efntegreerd met applicatiecode geschreven in C en C++. Naast de Scheme-taal, waarvoor ondersteuning is ge\u00efmplementeerd volgens de specificaties <noindex><a rel=\"nofollow\" href=\"http:\/\/www.schemers.org\/Documents\/Standards\/R5RS\/\">R5RS<\/a><\/noindex>, <noindex><a rel=\"nofollow\" href=\"http:\/\/www.r6rs.org\/\">R6RS<\/a><\/noindex> en <noindex><a rel=\"nofollow\" href=\"https:\/\/small.r7rs.org\/\">R7RS<\/a><\/noindex>, zijn er binnen het Guile-project ook compilers ontwikkeld voor andere talen, zoals ECMAScript, Emacs Lisp en Lua (in ontwikkeling). Het pakket bevat een bibliotheek met modules, waarin typische servicefuncties zijn ge\u00efmplementeerd, zoals HTTP-protocolbeheer, XML-parsering en het gebruik van methoden uit de objectgeori\u00ebnteerde programmering.<\/p>\n<p>Een belangrijke vernieuwing in GNU Guile 3.0 was de introductie van een JIT-compiler, naast de eerder aangeboden interpreter en compiler naar bytecode, die wordt uitgevoerd in een speciale virtuele machine die aan de applicatie is gekoppeld als een bibliotheek. JIT maakt het mogelijk om machinecode on the fly te genereren en versnelt de uitvoering van Guile-applicaties aanzienlijk (tests tonen snelheden tot 4 keer sneller aan). De JIT-compiler ondersteunt architecturen zoals x86-64, i686, ARMv7 en AArch64.<\/p>\n<p>Enkele andere verbeteringen:<\/p>\n<ul>\n<li class=\"l\"> Ondersteuning voor de nieuwe specificatie van de Scheme-taal <noindex><a rel=\"nofollow\" href=\"https:\/\/small.r7rs.org\/\">R7RS<\/a><\/noindex> en de daarin gedefinieerde bibliotheekmodules;\n<li class=\"l\"> In de Guile-virtuele machine is ondersteuning ge\u00efmplementeerd voor een laag-niveau bytecode, die uitgebreide optimalisaties mogelijk maakt;\n<li class=\"l\"> Ondersteuning voor het combineren van interne define-definities en -uitdrukkingen (bijvoorbeeld &#171;(define _ (begin (foo) #f))&#187;);\n<li class=\"l\"> Een uniforme implementatie van gestructureerde datatypen (&#171;records&#187;);\n<li class=\"l\"> Verbeteringen in de primitieve uitzonderingsverwerking (throw en catch);\n<li class=\"l\"> Bindings voor de uitgebreide syntaxis &#171;else&#187;, &#171;=&gt;&#187;, &#171;&#8230;&#187; en &#171;_&#187; zijn gedefinieerd;\n<li class=\"l\"> In http-request, http-get en andere gerelateerde webclientprocedures is de mogelijkheid toegevoegd om inhoud te laden via een versleuteld communicatiekanaal met TLS en een correcte certificatavalidatie.\n<\/ul>\n<p><noindex><a rel=\"nofollow\" name=\"link\"><\/a><\/noindex><\/p>\n<p>Bron: <a \ncontent=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=52203\">opennet.ru<\/a><\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u0421\u043e\u0441\u0442\u043e\u044f\u043b\u0441\u044f \u0440\u0435\u043b\u0438\u0437 GNU Guile 3.0, \u0441\u0432\u043e\u0431\u043e\u0434\u043d\u043e\u0439 \u0440\u0435\u0430\u043b\u0438\u0437\u0430\u0446\u0438\u0438 \u0444\u0443\u043d\u043a\u0446\u0438\u043e\u043d\u0430\u043b\u044c\u043d\u043e\u0433\u043e \u044f\u0437\u044b\u043a\u0430 \u043f\u0440\u043e\u0433\u0440\u0430\u043c\u043c\u0438\u0440\u043e\u0432\u0430\u043d\u0438\u044f Scheme, \u043f\u043e\u0434\u0434\u0435\u0440\u0436\u0438\u0432\u0430\u044e\u0449\u0435\u0439 \u0432\u043e\u0437\u043c\u043e\u0436\u043d\u043e\u0441\u0442\u044c \u0432\u0441\u0442\u0440\u0430\u0438\u0432\u0430\u043d\u0438\u044f \u043a\u043e\u0434\u0430 \u0432 \u043f\u0440\u0438\u043b\u043e\u0436\u0435\u043d\u0438\u044f \u043d\u0430 \u0434\u0440\u0443\u0433\u0438\u0445 \u044f\u0437\u044b\u043a\u0430\u0445 \u043f\u0440\u043e\u0433\u0440\u0430\u043c\u043c\u0438\u0440\u043e\u0432\u0430\u043d\u0438\u044f.
