Isetyenziswa se-regex esibonakalayo

Yakha i-regex. Jonga zonke iimatch. Yigcinele ixesha elizayo.

Ukukhanya okuphilayo, isibonisi seqela lokubamba, iingcaciso zolwimi olulula, kunye nethala leencwadi elikhethiweyo leepatheni ozibhala rhoqo.

Yeka ukunamathisela i-regex kwi-Stack Overflow

Vavanya, chaza, gcina — ngaphandle kokushiwa iphepha okanye ulahlekelwe ngumsebenzi wakho.

Ukukhanya okuphilayo kwe-match

Bhala i-regex, bhala umtya ovavanywayo — yonke imatch iyakhanya ngoko nangoko. Amaqela okubamba aboniswa ngaphakathi nokuxhaswa kweqela elinamagama.

Ingcaciso yolwimi olulula

Ncamathisela nayiphi na i-regex, ufumane ingcaciso inyathelo ngenyathelo: lookbehind, anchors, iiklasi zoonobumba, ii-quantifiers, iiflags. Yonke into ichazwe ngesiNgesi esiqhelekileyo.

Ithala leencwadi leepatheni

I-imeyile, i-URL, i-IPv4, i-IPv6, i-UUID, i-ISO-8601, inombolo yefowuni, ikhadi letyala, i-slug, umbala we-hex — iipatheni ezikhethiweyo ezidlula iimeko zokwenyani (hayi ezo zomgca ozi-5 kwi-Stack Overflow).

Gcina eyakho

Yonke i-regex oyibhalayo — yinike igama, yinike ithagi, buyela kuyo. Iiakhawunti zePro zivumelanisa ilifu kuzo zonke izixhobo.

Imowudi yokutshintsha

Vavanya utshintsho nge-backreferences ($1, $2). Jonga kanye oko ucingo lwakho lwe-sed / JS .replace() luya kuvelisa.

Iintlobo ezininzi

Tshintsha phakathi kweentlobo zeJavaScript, PCRE kunye nePOSIX. RegexBuilder ikuxelela ukuba zeziphi iimpawu ezixhaswayo kwenye neye.

Ukusuka kwinto engacacanga ukuya kwi-regex evavanyiweyo echaziweyo.

Khetha okanye ncamathisela

Qala ngepatheni yethala leencwadi okanye ncamathisela i-regex sele uyibhale.

Vavanya

Imibuzo eqhelekileyo

Zeziphi iintlobo zerejeksi oyixhasayo?

JavaScript (default), ehambelana ne-PCRE, kunye ne-POSIX. Sibonisa ngokucacileyo iimpawu ezingaxhaswayo xa utshintsha iintlobo.

Ingaba umtya wam wokuvavanya uyaphuma kwibhrawuza yam?

Hayi. Konke kusebenza kwicala lomsebenzisi; asithumeli irejeksi yakho okanye imitya yokuvavanya kwi-server ngaphandle kokuba ukhetha ukuvumelanisa iipatheni zakho ezigciniweyo kwifowuni.

Ingaba ingachaza irejeksi endingayibhaleyo?

Ewe — yena kanye lo nto eyenza umcacisi. Ncamathisa nayiphi na irejeksi ufumane ukuqhekeka okucacileyo inyathelo ngenyathelo.

Ndifumana ithuba lokuzama lasimahla?

Hayi — esi sisixhobo esihlawulwayo esineepakethe ezisukela kwi-$5 ngenyanga. I-Starter yi-$5/mo kwaye i-Pro yi-$15/mo; unokukhansela nangaliphi na ixesha.

Ndikhanisela njani?

Kwiphepha le-akhawunti yakho, okanye ngokuthumela i-imeyile. Ukurhoxisa kuyayima ukuvuselelwa okulandelayo.
