RE #: momwe tidapangira injini yachangu kwambiri ya regex mu F #

Kutulutsa Liwiro Losayerekezeka: Philosophy Kumbuyo kwa RE#

M'dziko lazachitukuko cha mapulogalamu, mawu okhazikika ndi chida chofunikira chofotokozera ndikutsimikizira mawu. Komabe, monga wopanga aliyense akudziwa, regex yosakometsedwa bwino imatha kukhala vuto lalikulu, kuchedwetsa kukonza kwa data ndikukhudza zomwe ogwiritsa ntchito akukumana nazo. Ku Mewayz, komwe bizinesi yathu yokhazikika ya OS idapangidwa kuti izigwira ntchito zovuta zamabizinesi ndikuchita bwino kwambiri, sitinathe kulipira zovuta zotere. Tinkafuna injini ya regex yomwe inali yamphamvu komanso yothamanga kwambiri. Izi zidatitsogolera paulendo womanga RE #, injini yogwira ntchito kwambiri ya regex yolembedwa kwathunthu mu F #. Cholinga chathu chinali kupititsa patsogolo paradigm yoyamba ya F# kuti tipeze yankho lomwe limaposa malaibulale a C++ okongoletsedwa kwambiri, ndipo zidatheka.

Chifukwa chiyani F# ya Regex Engine?

Kusankha kwa F# kunali kwadala komanso mwanzeru. Ngakhale zilankhulo monga C kapena C++ nthawi zambiri zimakhala zosasinthika pama code ofunikira, tinkakhulupirira kuti mawonekedwe apadera a F # anali oyenererana ndi kayendetsedwe ka boma komwe kamakhala pakuwunika kwa regex. Kufananiza kwake kwamphamvu, kusasinthika mwachisawawa, komanso mawonekedwe amtundu wamtunduwu zidatilola kutengera dera lamavuto mwachilengedwe komanso opanda malo olakwika. M'malo molimbana ndi kasamalidwe ka kukumbukira pamanja ndi malingaliro ovuta a pointer, titha kuyang'ana pa algorithm yayikulu. Izi zimagwirizana bwino ndi filosofi ya Mewayz yomanga ma modules olimba, osasunthika, komanso apamwamba omwe amapanga msana wa machitidwe odalirika a bizinesi. F# idatipatsa mphamvu kuti tilembe khodi yachangu komanso yolondola.

Kupanga Magwiridwe: Kuchokera ku NFA mpaka Kuphatikizidwe Kwamachitidwe

Pakatikati pake, injini zambiri za regex zimamangidwa pa Non-deterministic Finite Automaton (NFA). Vuto liri pa momwe mumatengera automaton iyi. Ma injini achikhalidwe nthawi zambiri amagwiritsa ntchito chitsanzo chomasulira, chomwe chimayenda ndi NFA pang'onopang'ono pamtundu uliwonse. RE# imatenga njira ina, yaukali kwambiri: timapanga mawonekedwe a regex mwachindunji mu ntchito yapadera ya F # panthawi yothamanga. Njirayi, yomwe imadziwika kuti Just-in-Time (JIT) compilation, imasintha mawonekedwe ang'onoang'ono kukhala khodi ya NET Intermediate Language (IL). Chotsatira chake ndi chakuti kufananitsa chingwe sikuphatikizanso kutanthauzira mawonekedwe a graph, koma kuchita ntchito yopangidwa mwaluso yomwe imayang'ana chekeyo mozungulira. Zigawo zazikulu zamamangidwe athu ndi izi:

• Kuwola Kwachitsanzo: Kuphwanya pateni ya regex kukhala Mtengo Wosasinthika wa Abstract Syntax Tree (AST).
• IL Code Generation: Kutulutsa mwachangu malangizo a IL omwe akuyimira malingaliro ofanana.
• Mapangidwe Osasunga Cache: Kusunga movutikira kumapangidwa kuti tipewe kubwezanso pamapateni omwe amagwiritsidwa ntchito pafupipafupi.
• Zero-Overhead Backtracking: Kukhazikitsa zowongolera zobwerera m'mbuyo pogwiritsa ntchito magwiridwe antchito a F# komanso kukhathamiritsa kwa kuyimba mchira.

Kuphatikizikaku ndiye chifukwa chachikulu RE# imakwaniritsa liwiro lake, nthawi zambiri kumachepetsa nthawi yofananira ndi kuchuluka kwa anthu omwe akuphedwa.

"Popanga mapangidwe a regex kukhala IL yokongoletsedwa bwino, timachotsa bwino omasulira, kulola RE# kuchita bwino kuposa mainjini olembedwa m'zilankhulo zotsika. Ndi umboni wa mphamvu za F#'s metaprogramming capations." - Injiniya Wotsogolera, Gulu la Mewayz Core

Kuphatikiza ndi Zotsatira mkati mwa Mewayz OS

Kukula kwa RE# sikunali ntchito yamaphunziro; idayendetsedwa ndi zosowa zenizeni za nsanja ya Mewayz. Bizinesi yathu OS imadalira kukonza kwachangu kwa data pachilichonse kuyambira kusanthula kwanthawi yeniyeni ndi kuyika logi mpaka kutsimikizira kuyika kwa ogwiritsa ntchito ndikusintha mitsinje ya data. Asanafike RE#, tidakumana ndi zovuta m'ma module omwe amalowetsa ndi kutsimikizira. Mwa kuphatikiza RE# ngati injini yokhazikika ya regex kudutsa Mewayz OS, tidawona kusintha kwaposachedwa komanso kochititsa chidwi. Mapaipi opangira ma data omwe poyamba ankavutika ndi katundu wolemetsa tsopano akugwira ntchito bwino, kuonetsetsa kuti makasitomala athu amatha kupanga ndi kuyendetsa zovuta, zogwiritsa ntchito deta popanda kudandaula za kuchedwa kwa malemba. Kuchita bwino kumeneku kumapangitsa kuti chilengedwe chonse chikhale bwino, ndikupangitsa gawo lililonse lomwe limadalira kusintha mawu kukhala lomvera komanso lowopsa.

Mapeto: Maziko a Zamtsogolo Zatsopano

Kupanga injini ya regex yothamanga kwambiri mu F# kunali kupambana kwakukulu komwe kumatsimikizira kudzipereka kwa Mewayz pakuchita bwino kwambiri. RE# imatsimikizira kuti kusankha chinenero ngati F # kwa oyambitsa ergonomics sikutanthauza kusiya ntchito; kwenikweni, ikhoza kukhala kiyi yotsegula. Kupambana kwa pulojekitiyi kumapereka maziko olimba a ma module amtsogolo mkati mwa Mewayz OS, kuwonetsetsa kuti tikamawonjezera zida zamphamvu zopangira makina ogwiritsira ntchito komanso kusanthula deta, kuthekera kwathu kosinthira zolemba sikudzakhala cholepheretsa. Tapanga injini yothamanga kwambiri masiku ano, koma yopangidwa kuti ikwaniritse zovuta za data zamawa.
