No dia 16 de janeiro, ocorreu o lan\u00e7amento da vers\u00e3o principal do GNU Guile \u2014 uma implementa\u00e7\u00e3o integrada da linguagem de programa\u00e7\u00e3o Scheme com suporte a multi-threading, ass\u00edncronas, manipula\u00e7\u00e3o de redes e chamadas de sistema POSIX, interface bin\u00e1ria C, an\u00e1lise PEG, REPL pela rede, XML; possui seu pr\u00f3prio sistema de programa\u00e7\u00e3o orientada a objetos.<\/p>\n

A principal caracter\u00edstica da nova vers\u00e3o \u00e9 o suporte completo \u00e0 compila\u00e7\u00e3o JIT, o que permitiu acelerar a execu\u00e7\u00e3o de programas em m\u00e9dia em duas vezes, com um m\u00e1ximo de trinta e duas vezes para o benchmark mbrot. Em compara\u00e7\u00e3o com a m\u00e1quina virtual Guile da vers\u00e3o anterior, o conjunto de instru\u00e7\u00f5es se tornou mais de baixo n\u00edvel.<\/p>\n

<\/p>\n

Al\u00e9m disso, houve melhorias na compatibilidade com os padr\u00f5es da linguagem de programa\u00e7\u00e3o Scheme R5RS e R7RS, incluindo suporte a exce\u00e7\u00f5es estruturadas<\/a> e declara\u00e7\u00f5es e express\u00f5es alternadas<\/a> dentro do contexto lexical. O eval escrito em Scheme agora tem desempenho equivalente ao correspondente em C; Para diferentes implementa\u00e7\u00f5es do tipo Record, foi fornecido um conjunto unificado de ferramentas para trabalhar com eles; As classes no GOOPS deixaram de ser sobrescrev\u00edveis; Detalhes e outras altera\u00e7\u00f5es podem ser lidos no an\u00fancio de lan\u00e7amento.<\/p>\n

<\/noindex><\/noindex><\/p>\n

A nova vers\u00e3o est\u00e1vel da linguagem agora \u00e9 a 3.x. Ela \u00e9 instalada paralelamente \u00e0 vers\u00e3o est\u00e1vel anterior 2.x.<\/p>\n
