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

Isidingo sesantya: Xa uPhendlo luba yiBottleneck

Ehlabathini lophuhliso lwesoftware kunye nolawulo lweenkqubo, ukukwazi ukukhangela ngokukhawuleza kwiintaba zekhowudi kunye neefayile zetekisi ayiyona nto inqabileyo; yimfuneko. Kangangeminyaka, izixhobo ezinje `grep` ibingamahashe okusebenza athembekileyo. Emva koko kwafika isizukulwana esitsha "sokukhangela amaqhawe amakhulu" anje nge `ag` (ISiliva iSeandi) kunye nabanye, sithembisa isantya esivuthayo ngokungahoywa kwezalathisi zolawulo lwenguqulelo kunye nokwandisa ubukrelekrele. Nangona kunjalo, ngo-2016, umntu omtsha okhuphisanayo wavela kwaye waphumelela ngokugqibeleleyo imilinganiselo yokusebenza. Eso sixhobo `ripgrep` (rg), kwaye ibali layo liyi-masterclass ekuphuculeni okugxilileyo okubonisa ifilosofi emva kwamaqonga oshishino asebenzayo afana neMewayz, apho ukusebenza kunye namava omphuhlisi abaluleke kakhulu.

Kutheni uRipgrep eshiye uKhuphiswano ngasemva

I-Ripgrep, eyenziwe ngu-Andrew Gallant, ayizange iphucule ngokunyukayo kwizixhobo ezikhoyo; yaphinda yacinga indlela. Isantya sayo esingundoqo sivela kwindibaniselwano enamandla yobuchwepheshe. Okokuqala, isebenzisa injini yeRust ye-regex, ekhawulezayo kwaye ikhuselekile. Okona kubaluleke kakhulu, `i-ripgrep` iyagqibeka kukhangelo lolawulo oluphinda-phindayo ngelixa uhlonipha ngokuzenzekelayo imithetho yakho `.gitignore`, iqinisekisa ukuba awukhe uchithe imijikelo yokukhangela ngezinto zolwakhiwo okanye izinto ezixhomekeke kuwe. Inzuzo yayo ebalulekileyo yobugcisa kukukwazi ukukhetha ngobulumko isicwangciso esilungileyo sokukhangela. Kwimitya yokoqobo, isebenzisa i-hyper-optimized SIMD algorithm ebizwa ngokuba nguTeddy. Kwiipateni ezintsonkothileyo zeregex, itshintshela ngaphandle komthungo kwinjini efanelekileyo. Le ndlela ikrelekrele ithetha ukuba isoloko isebenzisa eyona ndlela ikhawulezayo kumbuzo wakho.

"i-ripgrep ikhawuleza ngakumbi kune- {grep, ag, git grep, ucg, pt, sift} kuba yakhiwe phezulu kwe-injini ye-regex ye-Rust esebenzisa i-automata enesiphelo, i-SIMD kunye nokulungiswa okuthe ngqo ukwenza ukukhangela ngokukhawuleza." – Andrew Gallant, ripgrep umdali.

Ibenchmark Etshintshe iingqondo

Ibenchmark edumileyo ka-2016, eyenza isiseko sesihloko senqaku, ibibanzi. Ivavanye izixhobo zokukhangela kuluhlu olubanzi lweemeko ezinokwenyani: ukukhangela isilawuli esikhulu sekhowudi, ukuzingela igama lokoqobo, usebenzisa iintetho eziqhelekileyo ezintsonkothileyo, kunye nokucoca ngeefayile ezinkulu ezingatshatanga. I-Ripgrep ihlala ibeka phezulu iitshathi. Ngelixa izixhobo ezikhethekileyo zinokuphumelela kudidi olunye, olumxinwa, `ripgrep` igqwese kwibhodi iphela. Lo msebenzi ungaguquguqukiyo, othembekileyo yiloo nto eyenza ukuba ibambelele. Abaphuhlisi kunye nee-sysadmins bafumanise ukuba ukuthatha `i-ripgrep` kususa ingqondo engaphezulu yokukhetha izixhobo ezahlukeneyo zemisebenzi eyahlukeneyo. Kuphuhliso lwangoku lokuhamba komsebenzi, apho isantya kunye nokutshintsha umxholo kubaluleke kakhulu, ukuba nesixhobo esinye esithembekileyo, esikhawulezayo kuzo zonke iimfuno zokukhangela kukwandisa imveliso. Lo mgaqo wokumanyanisa ukusebenza ngobuchule ngulowo esiwuqonda ngokunzulu eMewayz, apho ukudibanisa imisebenzi eyahluka-hlukeneyo yeshishini kwi-OS emanyeneyo kusindisa amaqela ekutshintsheni okuthe gqolo kwesicelo.

Ngakumbi kunesantya esikrwada nje: Umda wamava oMsebenzisi

Intsebenzo ayikho malunga ne-milliseconds; imalunga namava ewonke. I-Ripgrep ithunyelwe ngezinto ezingagqibekanga ezinengqiqo ezihambelana nokusebenza komphuhlisi wale mihla ngaphandle kwebhokisi. Ukukhutshwa kwayo okukhazimlayo, kunye nekhowudi yombala ecocekileyo kunye namanani emigca, yenza iziphumo zifundeke ngoko nangoko. Iimpawu eziphambili ezibe negalelo kukwamkelwa kwayo ngokukhawuleza ziquka:

• Ukuhlonipha `.gitignore` ngokungagqibekanga kukhangelo olufanelekileyo, olukhawulezayo.
• Ukukhangela iifayile ezifihliweyo kunye neefayile zokubini kuphela xa zibuzwa ngokucacileyo.
• Inkxaso ye-Unicode "esebenzayo nje," ikhusela ukusilela kwepateni ephazamisayo.
• Ukwazi ukukhangela ngaphakathi kweentlobo zefayile ezithile usebenzisa isivakalisi esilula (umzekelo, `rg -tjs 'function'`).

Olu gxininiso kumava aphezulu angagqibekanga athethe ukuba abaphuhlisi bachithe ixesha elincinane besenza iiflegi zomgca womyalelo ofihlakeleyo kunye nexesha elininzi lokuvelisa. Isuse ukruthakruthwano, njengokuba iMewayz ijolise ekususeni ukruthakruthwano olusebenzayo ngokubonelela nge-OS yemodyuli yeshishini apho izixhobo zidityaniswa ngokungenamthungo, zivumela amaqela ukuba agxile kumsebenzi wawo ongundoqo endaweni yokumisela iinkqubo ezingadibaniyo.

Ilifa Elihlala Lihleli: Isantya njengophawu

Ibenchmark ka-2016 yayingengomfanekiso nje wexesha; ibonise utshintsho kulindelo. U-Ripgrep ubonakalise ukuba izixhobo zokuphuhlisa isiseko zinokuphinda zenziwe kwakhona kwixesha langoku ngeziphumo ezimangalisayo. Impumelelo yayo igxininise ukuba kwisixhobo, isantya ekrwada luphawu olunzulu-lunciphisa ixesha lokulinda kwi-loop yengxelo yophuhliso, ukwenza uphononongo, ukulungisa iimpazamo, kunye nokwenza izinto zibe lula. Kwisoftware yokwakha amashishini, ukhetho lwezixhobo ezisebenzayo lunempembelelo ethe ngqo kwisantya kunye nokuziphatha. Ngendlela efanayo, ukukhetha inkqubo esebenzayo yoshishino efana neMewayz, eyenzelwe isantya kunye nokudibanisa, inokuguqula i-agility yentlangano. Kanye njengokuba `ripgrep` iphucule ukuhamba kwekhowudi yokufumana, iMewayz ikhulisa ukuhamba kolwazi lweshishini, iqinisekisa ukuba amaqela akashiywa elindile kwizixhobo zabo.
