\u041f\u0440\u0435\u0434\u0441\u0442\u0430\u0432\u043b\u0435\u043d<\/a><\/noindex> prvi izdanak alata PyOxidizer<\/a><\/noindex>, koji omogu\u0107ava pakovanje projekta napisanog u Pythonu u oblik samostalne izvr\u0161ne datoteke, koja uklju\u010duje Python interpreter i sve potrebne biblioteke i resurse. Takve datoteke mogu se izvr\u0161avati u okru\u017eenjima bez instaliranog Python alata ili nezavisno od dostupnosti odgovaraju\u0107e verzije Pythona. PyOxidizer tako\u0111e mo\u017ee formirati stati\u010dki povezane izvr\u0161ne datoteke koje nisu vezane za sistemske biblioteke. Kod projekta je napisan na jeziku Rust i se distribuira<\/a><\/noindex> pod MPL licencom (Mozilla Public License) 2.0. <\/p>\n

Projekt se temelji na istoimenom modulu za jezik Rust, koji omogu\u0107ava ugra\u0111ivanje Python interpreter-a u Rust programe radi pokretanja Python skripti. PyOxidizer je sada pre\u0161ao granice dodatka za Rust i pozicionira se kao alat dostupniji \u0161iroj publici za formiranje i distribuciju samostalnih paketa sa Python-om. Za one kojima nije potrebno distribuirati aplikacije u obliku izvr\u0161ne datoteke, PyOxidizer pru\u017ea mogu\u0107nosti za generisanje biblioteka koje se mogu povezivati sa bilo kojim aplikacijama za ugra\u0111ivanje Python interpreter-a i potrebnog skupa ekstenzija.<\/p>\n

Za krajnje korisnike, isporuka projekta u obliku jedne izvr\u0161ne datoteke zna\u010dajno olak\u0161ava instalaciju i elimini\u0161e potrebu za radom na uskla\u0111ivanju zavisnosti, \u0161to je posebno va\u017eno za kompleksne projekte na Python-u, kao \u0161to su video editori. Za programere aplikacija, PyOxidizer omogu\u0107ava u\u0161tedu vremena na organizaciji isporuke aplikacije, bez potrebe za kori\u0161\u0107enjem razli\u010ditih alata za formiranje paketa za razli\u010dite operativne sisteme.<\/p>\n

Uporaba predlaganih paketov tudi pozitivno vpliva na zmogljivost \u2014 datoteke, ustvarjene v PyOxidizerju, se za\u017eenejo hitreje kot pri uporabi sistemskega Pythona, saj se izognejo uvozu in definiciji osnovnih modulov. V PyOxidizerju se moduli uva\u017eajo iz pomnilnika \u2014 vsi vgrajeni moduli se takoj nalo\u017eijo v pomnilnik in nato uporabljajo brez dostopa do diska). V testih se \u010das za zagon aplikacije pri uporabi PyOxidizerja zmanj\u0161a pribli\u017eno za polovico.<\/p>\n

Od ve\u0107 postoje\u0107ih sli\u010dnih projekata mo\u017ee se istaknuti: PyInstaller<\/a><\/noindex> (raspakovava fajl u privremeni katalog i unosi module iz njega), py2exe<\/a><\/noindex> (vezana za Windows platformu i zahteva distribuciju vi\u0161e datoteka), py2app<\/a><\/noindex> (vezana za macOS), cx-freeze<\/a><\/noindex> (zahteva posebno pakovanje zavisnosti), Shiv<\/a><\/noindex> in PEX<\/a><\/noindex> (formira paket u zip formatu i zahteva prisustvo Pythona u sistemu), Nuitka<\/a><\/noindex> (kompajlira kod, a ne ugra\u0111uje interpreter), pynsist<\/a><\/noindex> (vezana za Windows), PyRun<\/a><\/noindex> (proprietarna razvojna verzija bez obja\u0161njenja principa rada).<\/p>\n

U trenutnoj fazi razvoja, PyOxidizer ve\u0107 ima osnovnu funkcionalnost za generisanje izvr\u0161nih datoteka za Windows, macOS i Linux. Od trenutnih nedostupnih mogu\u0107nosti, se opozarja<\/a><\/noindex> pomanjkanje standardnega okolja za gradnjo, nezmo\u017enost generiranja paketov v formatih MSI, DMG in deb\/rpm, te\u017eave pri pakiranju projektov, ki vklju\u010dujejo kompleksne raz\u0161iritve v jeziku C, pomanjkanje ukazov za podporo dostavi (\u00bbpyoxidizer add\u00ab, \u00bbpyoxidizer analyze\u00ab in \u00bbpyoxidizer upgrade\u00ab), omejena podpora za Terminfo in Readline, pomanjkanje podpore za razli\u010dice, ki niso Python 3.7, pomanjkanje podpore za stiskanje virov, nezmo\u017enost kri\u017enega prevajanja.<\/p>\n
