Foi lan\u00e7ado o pacote uutils coreutils 0.0.12, que desenvolve uma alternativa ao pacote GNU Coreutils, reescrito na linguagem Rust. O coreutils inclui mais de cem utilit\u00e1rios, incluindo sort, cat, chmod, chown, chroot, cp, date, dd, echo, hostname, id, ln e ls. Simultaneamente, foi lan\u00e7ado o pacote uutils findutils 0.3.0 com a implementa\u00e7\u00e3o em Rust dos utilit\u00e1rios do conjunto GNU Findutils (find, locate, updatedb e xargs). <\/p>\n

A raz\u00e3o para a cria\u00e7\u00e3o do projeto e o uso da linguagem Rust \u00e9 o desejo de criar uma implementa\u00e7\u00e3o alternativa e multiplataforma do Coreutils e Findutils, capaz de funcionar tamb\u00e9m em plataformas Windows, Redox e Fuchsia. Outra diferen\u00e7a importante do uutils \u00e9 a distribui\u00e7\u00e3o sob a licen\u00e7a permissiva MIT, em vez da licen\u00e7a copyleft GPL. <\/p>\n

Atualmente, a implementa\u00e7\u00e3o de 88 utilit\u00e1rios est\u00e1 totalmente equiparada ao GNU Coreutils. Algumas lacunas s\u00e3o notadas em 18 utilit\u00e1rios, incluindo cp, dd, date, df, install, ls, more, sort, split, tail e test. Apenas o utilit\u00e1rio stty permanece n\u00e3o implementado. Durante a execu\u00e7\u00e3o do conjunto de testes do projeto GNU Coreutils, 214 testes s\u00e3o executados com sucesso, mas 313 testes da vers\u00e3o em Rust ainda n\u00e3o passam. Ao mesmo tempo, a intensidade do desenvolvimento do projeto aumentou visivelmente \u2014 agora adicionam-se de 400 a 470 patches por 20 a 50 desenvolvedores, em compara\u00e7\u00e3o com 30 a 60 de 3 a 8 desenvolvedores no ano passado.

\"Atualiza\u00e7\u00e3o<\/center> <\/p>\n

Entre os \u00faltimos avan\u00e7os, destaca-se a otimiza\u00e7\u00e3o de desempenho \u2014 no estado atual, muitos utilit\u00e1rios, como head e cut, superam significativamente em desempenho suas vers\u00f5es do GNU Coreutils. A cobertura do conjunto de testes foi ampliada de 55% para 75% de todo o c\u00f3digo (um objetivo desej\u00e1vel \u00e9 80%). Foi realizado um refatoramento do c\u00f3digo para simplificar a manuten\u00e7\u00e3o; por exemplo, o tratamento de erros foi unificado em diferentes programas, e em chgrp e chown, o c\u00f3digo para gerenciamento de permiss\u00f5es foi integrado. V\u00e1rias mudan\u00e7as foram adicionadas para melhorar a compatibilidade com o GNU Coreutils. <\/p>\n

Entre os planos futuros est\u00e3o a implementa\u00e7\u00e3o da ferramenta stty, a continuidade do trabalho para melhorar a compatibilidade com o GNU Coreutils, a adi\u00e7\u00e3o de otimiza\u00e7\u00f5es para reduzir o tamanho dos arquivos execut\u00e1veis, al\u00e9m da continua\u00e7\u00e3o dos experimentos com a utiliza\u00e7\u00e3o das ferramentas uutils em Debian e Ubuntu, em substitui\u00e7\u00e3o ao GNU Coreutils e ao GNU Findutils (um dos principais desenvolvedores do uutils j\u00e1 trabalhou no projeto de constru\u00e7\u00e3o do Debian GNU\/Linux usando o compilador Clang). Adicionalmente, est\u00e1 em preparo o pacote uutils-coreutils para macOS, experimentos para substituir o GNU Coreutils por uutils coreutils no NixOS, a inten\u00e7\u00e3o de usar uutils coreutils por padr\u00e3o na distribui\u00e7\u00e3o Apertis e a adapta\u00e7\u00e3o do conjunto uutils para o Redox OS.
