I-Ripgrep ishesha kune-grep, ag, git grep, ucg, pt, sift (2016)

Isidingo Sejubane: Uma Usesho Luba Ibhodlela

Emhlabeni wokuthuthukiswa kwesofthiwe nokuphathwa kwezinhlelo, ikhono lokusesha ngokushesha ezintabeni zekhodi kanye namafayela ombhalo akuyona into ewubukhazikhazi; kuyisidingo. Iminyaka eminingi, amathuluzi afana nokuthi `grep` bekungamahhashi okusebenza athenjwayo. Kube sekufika isizukulwane esisha "samaqhawe okusesha" afana `ne-ag` (Isisheli Sesiliva) namanye, athembisa isivinini esivuthayo ngokuziba izinkomba zokulawula inguqulo nokusebenzisa ukulungiselelwa okuhlakaniphile. Kodwa-ke, ngo-2016, kwavela imbangi entsha futhi yawina ngokunembile ama-benchmarks okusebenza. Lelo thuluzi lithi `ripgrep` (rg), futhi indaba yalo iyisigaba sobuciko ekuthuthukiseni okugxilile esibukisa ifilosofi ngemuva kwezinkundla zebhizinisi eziphumelelayo njenge-Mewayz, lapho ukusebenza nolwazi lonjiniyela kubaluleke kakhulu.

Kungani u-Ripgrep Ashiye Umncintiswano Ngemuva

I-Ripgrep, edalwe ngu-Andrew Gallant, ayizange ivele ithuthuke kancane kancane kumathuluzi akhona; yacabanga kabusha indlela. Ijubane layo eliwumgogodla livela ekuhlanganiseni okunamandla kobuchwepheshe. Okokuqala, isebenzisa injini ye-Rust's regex, eshesha ngendlela emangalisayo futhi ephephile. Okubaluleke nakakhulu, `i-ripgrep` ishintsha ngokuzenzakalelayo kusesho lwenkomba ephindaphindayo kuyilapho ihlonipha ngokuzenzekelayo imithetho yakho yokuthi `.gitignore`, iqinisekisa ukuthi awumoshi imijikelezo yokusesha ngama-artifact okwakhiwa noma okuncikile. Inzuzo yayo ebaluleke kakhulu yobuchwepheshe ikhono layo lokukhetha ngobuhlakani isu elilungile lokusesha. Ochungechungeni lwangempela, isebenzisa i-algorithm ye-SIMD eyenziwe nge-hyper-optimized ebizwa ngokuthi i-Teddy. Kumaphethini e-regex ayinkimbinkimbi, ishintshela enjinini efanele. Lo mgudu ohlakaniphile usho ukuthi cishe njalo usebenzisa indlela eshesha kakhulu embuzweni wakho othize.

"i-ripgrep iyashesha kune-{grep, ag, git grep, ucg, pt, sift} ngoba yakhiwe phezu kwenjini ye-Rust's regex esebenzisa i-automata ene-finite, i-SIMD kanye nokulungiselelwa okungokoqobo okunamandla ukwenza ukusesha kusheshe kakhulu." – Andrew Gallant, ripgrep umdali.

Ibhentshimakhi Eshintshe Imiqondo

Ibhentshimakhi edumile yango-2016, eyenza isisekelo sesihloko se-athikili, ibiphelele. Ihlole amathuluzi okusesha ezimweni eziningi ezingokoqobo: ukucinga uhlu lwemibhalo olukhulu lwekhodi, ukuzingela igama elingokoqobo, kusetshenziswa izinkulumo ezivamile eziyinkimbinkimbi, nokuhlunga ngamafayela amakhulu angawodwa. I-Ripgrep ihlale iphezulu kumashadi. Nakuba amathuluzi akhethekile angase awine esigabeni esisodwa, esiwumngcingo, `ripgrep` iphumelele ebhodini lonke. Lokhu kusebenza okungaguquguquki, okuthembekile yikhona okwenze yanamathela. Onjiniyela nama-sysadmins bathole ukuthi ukuthatha `i-ripgrep` kuqede ukugxila kwengqondo ekukhetheni amathuluzi ahlukene emisebenzi eyahlukene. Ekuthuthukisweni komsebenzi wesimanjemanje, lapho isivinini nokuguqulwa komongo kubalulekile, ukuba nethuluzi elilodwa elithembekile, elisheshayo lazo zonke izidingo zosesho kuwukuthuthuka okukhulu kokukhiqiza. Lesi simiso sokuhlanganisa ukusebenza kahle yileso esisiqonda ngokujulile e-Mewayz, lapho ukuhlanganisa imisebenzi yebhizinisi ehlukene ku-OS ehlangene kusindisa amaqembu ekushintsheni njalo kwezinhlelo zokusebenza.

Ngaphezulu Kunejubane Elingavuthiwe: I-Edge Yokuzizwisa Umsebenzisi

Ukusebenza akukhona nje ama-millisecond; imayelana nolwazi oluphelele. I-Ripgrep ihanjiswe ngokuzenzakalelayo okunengqondo okufana nokugeleza komsebenzi kanjiniyela wesimanje ngaphandle kwebhokisi. Ukukhishwa kwayo okupholishiwe, okunombhalo wekhodi ohlanzekile nezinombolo zomugqa, kwenze imiphumela yafundeka ngokushesha. Izici ezibalulekile ezibe nomthelela ekwamukelweni kwayo ngokushesha zihlanganisa:

• Ukuhlonipha `.gitignore` ngokuzenzakalelayo ukuze uthole ukusesha okuhlobene, okusheshayo.
• Isesha amafayela afihliwe namafayela kanambambili kuphela uma ebuzwa ngokucacile.
• Usekelo lwe-Unicode "oluvele lusebenze," lugweme ukuhluleka kwephethini okukhungathekisayo.
• Ikhono lokusesha ngaphakathi kwezinhlobo ezithile zamafayela usebenzisa i-syntax elula (isb., `rg -tjs 'function'`).

Lokhu kugxila kokuhlangenwe nakho okuzenzakalelayo okuphezulu kusho ukuthi onjiniyela bachithe isikhathi esincane benza amafulegi omugqa womyalo angacacile kanye nesikhathi esengeziwe sokukhiqiza. Kususe ukungqubuzana, kufana nokuthi i-Mewayz ihlose ukususa ukungqubuzana kokusebenza ngokuhlinzeka nge-OS yebhizinisi eyimodulayo lapho amathuluzi ehlangana khona ngaphandle komthungo, okuvumela amaqembu ukuthi agxile emsebenzini wawo oyinhloko esikhundleni sokumisa amasistimu ahlukene.

Ifa Elihlala Njalo: Isivinini Njengesici

Ibhentshimakhi yango-2016 kwakungesona nje isifinyezo ngesikhathi; kwabonisa ukushintsha kokulindelwe. U-Ripgrep ufakazele ukuthi amathuluzi onjiniyela ayisisekelo angahlelwa kabusha enkathini yesimanje ngemiphumela emangazayo. Ukuphumelela kwayo kugcizelele ukuthi ekusetshenzisweni kwamathuluzi, isivinini esingahluziwe siyisici esijulile—sinciphisa ukubambezeleka ku-loop yempendulo yokuthuthukisa, kwenze ukuhlola, ukulungisa amaphutha, kanye nokwenza kabusha kungabi nesicefe. Kuhlelo lwesoftware yokwakha amabhizinisi, ukukhethwa kwamathuluzi asebenzayo kunomthelela oqondile kusivinini kanye nesimilo. Ngendlela efanayo, ukukhetha uhlelo olusebenzayo lwebhizinisi olufana ne-Mewayz, eklanyelwe isivinini nokuhlanganiswa, kungaguqula ukusebenza kwenhlangano. Njengoba nje `i-ripgrep` ithuthukise ukuhamba kwekhodi yokuthola, i-Mewayz ithuthukisa ukuhamba kolwazi lwebhizinisi, iqinisekisa ukuthi amaqembu awashiywa elindile kumathuluzi awo.
