Esitletud on rars projekt, mis arendab avatud teostust RAR-formaadi t\u00f6\u00f6riistadest, kirjutatud Rust keeles ja toetab mitte ainult dekompressiooni, vaid ka RAR-aruandete loomist. T\u00f6\u00f6riistad toetavad nii varasemaid RAR 1.3\/1.4 formaate, millel on allkiri 'RE~^', kui ka viimast RAR 7 versiooni. Saadaval on laiendatud toimingud, nagu mahtude jagamine, paroolikaitse, pealkirjade kr\u00fcpteerimine, kommentaaride lisamine, RARVM-filterid, kiire avamise indeksid ja vigaste andmete taastamise mehhanismid. Kood on litsentseeritud MIT ja Apache-2.0 alusel. PyO3 raamatukogu p\u00f5hjal on valmis Python'i \u00fcmbermugandused, mis rakendavad rarfile stiilis API-d arhivate vaatamiseks, testimiseks ja v\u00e4ljav\u00f5tmiseks ning RarBuilder stiilis API-d arhivate loomimiseks v\u00f5i \u00fcmberpakendamiseks.<\/p>\n

Projekti erip\u00e4ra on see, et see rakendab RAR formaadiga t\u00f6\u00f6tamist ilma unrar utiliidi koodi kasutamata, mis on saadaval mittesvabaduse litsentsiga, mis keelab unrar koodi kasutamise RAR kokkusurumismeetodi taastamiseks v\u00f5i RAR-\u00fchilduva arhiivija arendamiseks. Selle piirangu t\u00f5ttu on enamik avatud arhiivijaid piirdunud vaid RAR-failide dekompressiooniga, samas kui RAR-arhiivide loomiseks on vajalik kasutada RARLAB-i omandi all oleva t\u00f6\u00f6riista.<\/p>\n

Erakordselt on loodud repository rar-research, kus on avaldatud spetsifikatsioonid RAR 1.3\/1.4, RAR 1.5-4.x ja RAR 5.0\/7.0 formaatide jaoks, samuti m\u00e4rkmed kasutatavate algoritmide, filtrite, kontrollimist ja taastamist\u00f5husust, kr\u00fcptimise, mahu jagamise ja kaitsemehhanismide kohta. Kuna projekti rars loomise hetkel ametlikku p\u00f5hjalikku spetsifikatsiooni ei olemas, loodi dokumentatsioon dekompresseerijate koodi, vanade rakenduste, testarhiivide ja RAR bin\u00e4\u00e4rversioonide anal\u00fc\u00fcsi p\u00f5hjal DOS ja Windows jaoks.<\/p>\n

Rakendus loodi kasutades OpenAI Codex 5.5 ja Claude Opus 4.7 AI t\u00f6\u00f6riistu, vabastatud t\u00f6\u00f6ajast, ligikaudu viie n\u00e4dala jooksul. Esimeses etapis kasutati mudeleid teabe s\u00fcstematiseerimiseks formaadi kohta ning kirjeldamise l\u00fcnkade t\u00e4itmiseks, seej\u00e4rel genereeriti taastatud spetsifikatsiooni p\u00f5hjal Rust keeles kood. Spetsifikatsiooni t\u00e4psustamiseks ja rakenduse viimistlemiseks kasutati reaalarhiivide testimist ning v\u00f5rdlemist etalonrakendustega.<\/p>\n

T\u00e4heldatakse, et AI- t\u00f6\u00f6riistad suudavad h\u00e4sti vormide kirjeldusi koodiks t\u00f5lkida ning teostada suurt hulka funktsionaalsust, kuid nad ei suuda tagada arhitektuurilist kontrolli. Ilma rangete j\u00e4relevalveta kipuvad AI-mudelid katseid ignoreerima, koodi keerulisemaks muutma ja ilmseid probleeme, mis m\u00f5jutavad t\u00f6\u00f6 mugavust, k\u00f5rvale j\u00e4tma. Autori hinnangul on sellise ulatuse projektis testid, dokumentatsioon ja kommentaarid muutunud mitte ainult kontrollimise vahenditeks, vaid ka viisiks suunata koodi genereerimist soovitud suunas.<\/p>\n

Arenduse sundimine \u00f5nnestus p\u00e4rast OpenAI Codex'i 'goal' re\u017eiimi ilmumist, mis v\u00f5imaldab AI-agendil t\u00f6\u00f6tada \u00fche \u00fclesande kallal pikka aega, sisse kokkusuruma konteksti ja j\u00e4tkama t\u00e4itmist p\u00e4rast selle \u00fcletamist. Selle re\u017eiimi ajal t\u00f6\u00f6tas Codex mitu korda rohkem kui 6 tundi ja \u00fchel korral umbes 16 tundi, rakendades suure osa \u00fclej\u00e4\u00e4nud funktsionaalsusest, n\u00e4iteks andmete taastamist, kr\u00fcpteerimist ja mitme mahuti arhiive. Arvestades olulisi toetusi tokenite jaoks, kulus 40 naela.<\/p>\n

Sisset\u00f5mbumise tasemelt j\u00e4\u00e4b rars keskmiselt 5-10% maha WinRAR-st. Sisset\u00f5mbe ja dekompressiooni kiirus on rars m\u00e4rgatavalt aeglasem kui WinRAR-l, kuna puuduvad t\u00e4ielikud optimeerimised. Sellegipoolest on projektis juba re\u017eiim '--features fast', mis rakendab SIMD-instruktsioone p\u00f5hinevaid optimeerimisi sisset\u00f5mbamise ja dekompressiooni kiirendamiseks, kuid on seotud eksperimentaalse API std::simd-ga, mis on saadaval ainult Rust t\u00f6\u00f6riistade testversioonides. Samuti on rakendatud re\u017eiim '--features parallel', mis kasutab Rayoni raamatukogu \u00fcksikfailide sisset\u00f5mbamise paralleliseerimiseks.<\/p>\n

Evgeny Roshal, RAR-i looja, kommenteeris vanade RAR binaarfailide tagurpidi inseneritehnoloogia kasutamist rars\u2019i arendamisel, mis on litsentsilepinguga keelatud. Evgeny s\u00f5nul ei ole ta veel otsustanud, mida sellega teha, ja plaanib oodata arvamust ettev\u00f5ttelt win.rar GmbH.
