Andreas Kling, zakladatel webov\u00e9ho prohl\u00ed\u017ee\u010de Ladybird, ozn\u00e1mil, \u017ee se rozhodl vyu\u017e\u00edt jazyk Rust p\u0159i v\u00fdvoji projektu a za\u010dal p\u0159episovat \u010d\u00e1sti Ladybird v tomto jazyce. Jako experiment byl JavaScriptov\u00fd engine LibJS ji\u017e p\u0159eps\u00e1n z C++ do Rustu.

Pro urychlen\u00ed portov\u00e1n\u00ed byly zapojeny AI asistenti Claude Code a OpenAI Codex, co\u017e umo\u017enilo p\u0159eps\u00e1n\u00ed k\u00f3du b\u011bhem dvou t\u00fddn\u016f.

Po z\u00edsk\u00e1n\u00ed k\u00f3du byly r\u016fzn\u00e9 AI modely podrobeny revizi a anal\u00fdze k\u00f3du na chyby a pochybn\u00e9 rozhodnut\u00ed. <\/p>\n

Je pozoruhodn\u00e9, \u017ee v roce 2024 se v\u00fdvoj\u00e1\u0159i Ladybird rozhodli pou\u017e\u00edt programovac\u00ed jazyk Swift, ale narazili na nedostate\u010dnou interoperabilitu s k\u00f3dem v C++ a omezenou podporu platforem jin\u00fdch ne\u017e Apple. Co se t\u00fd\u010de Rustu, je pro tento jazyk sice uvedena zralej\u0161\u00ed ekosyst\u00e9m pro syst\u00e9mov\u00e9 programov\u00e1n\u00ed a zaru\u010den\u00ed bezpe\u010dnosti. Krom\u011b toho je mezi v\u00fdvoj\u00e1\u0159i Ladybird mnoho \u00fa\u010dastn\u00edk\u016f, kte\u0159\u00ed znaj\u00ed tento jazyk. V roce 2024 nebyl jazyk Rust schv\u00e1len pro pou\u017eit\u00ed v Ladybird kv\u016fli paradigmat na z\u00e1klad\u011b vlastnictv\u00ed, kter\u00e9 se zcela nehodily k objektov\u011b orientovan\u00e9mu stylu C++. <\/p>\n

Andreas Kling kdysi pracoval ve spole\u010dnosti Nokia a zab\u00fdval se v\u00fdvojem KHTML, pot\u00e9 byl v Apple jedn\u00edm z v\u00fdvoj\u00e1\u0159\u016f Safari.
