Sylvestre Ledru, zn\u00e1my svojou pr\u00e1cou na zostavovan\u00ed Debian GNU\/Linux s pou\u017eit\u00edm kompil\u00e1tora Clang, ozn\u00e1mil \u00faspe\u0161n\u00e9 vykonanie experimentu s vyu\u017eit\u00edm alternat\u00edvneho s\u00faboru util\u00edt coreutils, prep\u00edsan\u00e9ho v jazyku Rust.

Pre prv\u00fa f\u00e1zu integr\u00e1cie variantu coreutils v jazyku Rust do Debianu boli stanoven\u00e9 nasleduj\u00face ciele: <\/p>\n
\n
Vytvorenie bal\u00edka s alternat\u00edvnym variantom coreutils v jazyku Rust pre Debian a Ubuntu.\n
Na\u010d\u00edtanie Debianu s pracovnou plochou GNOME, pou\u017e\u00edvaj\u00fac rust-coreutils.\n
In\u0161tal\u00e1cia 1000 najpopul\u00e1rnej\u0161\u00edch bal\u00edkov z repozit\u00e1ra.\n
Zostavenie z trieden\u00fdch zdrojov\u00fdch textov Firefox, LLVM\/Clang a jadra Linux v prostred\u00ed s rust-coreutils. <\/ul>\n
Po vytvoren\u00ed viac ako 100 patchov pre Rust\/coreutils sa podarilo \u00faspe\u0161ne realizova\u0165 v\u0161etky stanoven\u00e9 ciele. V pokra\u010duj\u00facej pr\u00e1ci sa spom\u00edna realiz\u00e1cia ch\u00fdbaj\u00facich util\u00edt a mo\u017enost\u00ed, zlep\u0161enie kvality a jednotnosti k\u00f3du, rozvoj testovacieho s\u00faboru a odstr\u00e1nenie ch\u00fdb, ktor\u00e9 sa vyskytovali pri spusten\u00ed testovacieho s\u00faboru od GNU Coreutils (doteraz \u00faspe\u0161ne prebehlo 141 testov zo 613). <\/p>\n
Pri vytv\u00e1ran\u00ed bal\u00edka rust-coreutils sa rozhodlo nezamie\u0148a\u0165 bal\u00edk coreutils, ale zabezpe\u010di\u0165 mo\u017enos\u0165 ich paraleln\u00e9ho fungovania. Varianty util\u00edt v jazyku Rust sa in\u0161taluj\u00fa do \/usr\/lib\/cargo\/bin\/ a aktivuj\u00fa sa pridan\u00edm tejto cesty do premennej prostredia PATH. Vytvorenie bal\u00edka rust-coreutils skomplikovala potreba na\u010d\u00edta\u0165 do repozit\u00e1ra v\u0161etky z\u00e1vislosti pre zostavovanie, vr\u00e1tane Rustu a r\u00f4znych drobn\u00fdch crate-bal\u00edkov. <\/p>\n
