Presentert<\/a><\/noindex> den f\u00f8rste utgaven av verkt\u00f8yet PyOxidizer<\/a><\/noindex>, som gj\u00f8r det mulig \u00e5 pakke et prosjekt skrevet i Python som en selvstendig kj\u00f8rbar fil som inkluderer Python-tolkeren og alle n\u00f8dvendige biblioteker og ressurser. Slike filer kan kj\u00f8res i milj\u00f8er uten installert Python-verkt\u00f8y eller uavhengig av hvilke versjoner av Python som er tilgjengelige. PyOxidizer kan ogs\u00e5 lage statisk sammenkoblede kj\u00f8rbare filer som ikke er avhengige av systembiblioteker. Prosjektkoden er skrevet i Rust og distribueres<\/a><\/noindex> lisensiert under MPL (Mozilla Public License) 2.0. <\/p>\n

Prosjektet er basert p\u00e5 den samme modulen for Rust som gj\u00f8r det mulig \u00e5 integrere Python-tolkeren i Rust-programmer for \u00e5 kj\u00f8re Python-skript. PyOxidizer har n\u00e5 g\u00e5tt utover \u00e5 v\u00e6re et tillegg for Rust og posisjonerer seg som et tilgjengelig verkt\u00f8y for en bredere brukergruppe for \u00e5 lage og distribuere selvstendige Python-pakker. For de som ikke trenger \u00e5 distribuere applikasjoner som kj\u00f8rbare filer, gir PyOxidizer muligheter for \u00e5 generere biblioteker som kan kobles til enhver applikasjon for \u00e5 integrere Python-tolkeren og det n\u00f8dvendige settet med utvidelser.<\/p>\n

For sluttbrukere gj\u00f8r distribusjonen av prosjektet som en enkelt kj\u00f8rbar fil installasjonen betydelig enklere og eliminerer behovet for \u00e5 h\u00e5ndtere avhengigheter, noe som er relevant for komplekse Python-prosjekter som videoredigerere. For applikasjonsutviklere lar PyOxidizer dem spare tid p\u00e5 \u00e5 organisere distribusjonen av applikasjonen, uten \u00e5 m\u00e5tte bruke ulike verkt\u00f8y for \u00e5 lage pakker for forskjellige operativsystemer.<\/p>\n

Bruken av de foresl\u00e5tte byggene har ogs\u00e5 en positiv effekt p\u00e5 ytelsen \u2014 filene som genereres i PyOxidizer starter raskere enn n\u00e5r man bruker systemets Python, fordi det eliminerer import og definisjon av grunnleggende moduler. I PyOxidizer importeres modulene fra minnet \u2014 alle innebygde moduler lastes umiddelbart inn i minnet og brukes deretter uten \u00e5 m\u00e5tte hente dem fra disken. I testene reduseres oppstartstiden for applikasjonen med omtrent halvparten n\u00e5r man bruker PyOxidizer.<\/p>\n

Blant eksisterende lignende prosjekter kan nevnes: PyInstaller<\/a><\/noindex> (dekomprimerer filen til en midlertidig katalog og importerer moduler fra den), py2exe<\/a><\/noindex> (bundet til Windows-plattformen og krever distribusjon av flere filer), py2app<\/a><\/noindex> (bundet til macOS), cx-freeze<\/a><\/noindex> (krever egen pakking av avhengigheter), Shiv<\/a><\/noindex> og PEX<\/a><\/noindex> (lager pakker i zip-format og krever at Python er installert i systemet), Nuitka<\/a><\/noindex> (kompilerer kode i stedet for \u00e5 integrere tolk), pynsist<\/a><\/noindex> (bundet til Windows), PyRun<\/a><\/noindex> (propriet\u00e6r utvikling uten forklaring av driftsprinsippene).<\/p>\n

P\u00e5 n\u00e5v\u00e6rende utviklingsstadium har PyOxidizer allerede implementert hovedfunksjonaliteten for \u00e5 generere kj\u00f8rbare filer for Windows, macOS og Linux. N\u00e5r det gjelder tilgjengelige funksjoner, merkes<\/a><\/noindex> mangel p\u00e5 standard byggeomgivelser, umulighet til \u00e5 generere pakker i formatene MSI, DMG og deb\/rpm, problemer med innpakking av prosjekter som inkluderer kompliserte utvidelser p\u00e5 C-spr\u00e5ket, mangel p\u00e5 kommandoer for \u00e5 st\u00f8tte distribusjonen (\u00abpyoxidizer add\u00bb, \u00abpyoxidizer analyze\u00bb og \u00abpyoxidizer upgrade\u00bb), begrenset st\u00f8tte for Terminfo og Readline, mangel p\u00e5 st\u00f8tte for versjoner annet enn Python 3.7, mangel p\u00e5 st\u00f8tte for ressurskomprimering, umulighet for krysskompilering.<\/p>\n
