Sichaza ukuthi yini ofuna ukuyilinganisa ngesiNgisi esilula futhi uthole i-regex ekhethekile — PCRE, JavaScript, Python, Go (RE2), noma POSIX — ngengxenye-ngengxenye yolwazi kanye nomlinganisi ophilayo obonisa ukufana nokulahleka.

Indlela yokusetshenziswa Umkhiqizi we-Regex
1
Faka isingeniso sakho
Bhala umbhalo, thumela ihele, noma chaza ofuna ukukwenza. Akukho akhawunti edingekayo.
2
Chofoza ukudala
I-AI yethu isebenza isicelo sakho emaminithini ambalwa usebenzisa amamodeli angcono kakhulu avulekile.
3
Layisha phezulu futhi uhlukanise
Layisha phezulu, kopela, noma uhlukanise imiphumela yakho. Imahhala ukusebenziseka komuntu siqu nebhizinisi.
Sebenzisa lesi sisetshenziswa nge-API
Yenza lokhu sixhobo sisebenze ngokuzenzakalela kusuka kukhodi yakho. I-REST ehambisanayo ne-OpenAI, ubufakazi be-token, akukho SDK edingekayo. Izindleko ze-token zifana ne-web interface.

Umkhiqizi we-Regex - FAQ
Ichaza ukuthi yini ofuna ukuyilinganisa ngesiNgisi esilula ("US zip codes", "all URLs except localhost", "balanced parentheses up to depth 3") futhi uthola i regex efanele nge-flavor-aware syntax (PCRE, JavaScript, Python re, Go regexp, POSIX), umbono ohamba phambili, kanye ne-test panel ebonisa imibhalo ekhona elingana vs. ayifani.
Regex101 / Regexr / Debuggex yizinto ezisetshenziswayo ze EXPLAINER - ubhala i regex, zichaza. Free.ai yi GENERATOR - uchaza ukuthi yini odinga ngesiNgisi, ibhala i regex. Sebenzisa i Free.ai ku- draft yokuqala, bese ufaka ku Regex101 ukuhlola idatha yakho ephilayo. Umsebenzi ohlangene ugcina amahora ngaphezulu kokubhala ngesandla i regex kusuka kukhasi lokukhangisa.
PCRE (iphutha ku-PHP, Perl, izinhlelo eziningi zeLinux). JavaScript (ibrowser + Node, akukho ukubheka emuva ku-Safari ≤16.3). Python re (iphakathi kwe-PCRE, akukho ukulinganisela okunesibopho). Go regexp (RE2 - akukho ukubhekisa emuva, akukho ukubheka emuva, kodwa isikhathi esihamba phambili siqinisekisiwe). POSIX BRE/ERE (grep, sed ngaphandle kwe- -E). Khetha enye i-language yakho efuna ukuyisebenzisa - izici ezifana nokubheka emuva / ukulinganisela okunesibopho / amaqembu abizwanga angeke afike kuzo zonke izithako.
Imibuzo ecacile: akukho regex efana nezo zonke izingeniso ze-real-world ngokugcwele. Ukuqinisekisa i-imeyili kuphela kune-6,425-isithombe "RFC 5322 ehambisanayo" regex akukho muntu osebenzisayo. Free.ai ibeka inhloso ye-99% yecala lokusetshenziswa okushoyo futhi itshela mayelana necala elibizwa nge-edge elisetshenziswe echaza (isibonelo, "lesi sifana ne-example.co.uk kodwa hhayi example.museum"). Qaphela ukuhlola idatha ebonakalayo ngaphambi kokuthumela kukhiqizwa.
Yebo - chofoza i-regex kwibhokisi lokubonisa eliqanjiwe nge-"explain: " (isibonelo, `explain: ^(?=.*[A-Z])(?=.*\d).{8,}$`) futhi imodeli izohlukanisa yonke i-token futhi izokutshela ukuthi ifana kanjani. Sebenzisa /code/explain/ ukunikeza ubufakazi obuningi bokuthi ikhodi ikhona.
Yebo - uma i-flavour ekhethiwe ixhasa lokhu. PCRE/Python/JS ivumela ukubuka emuva okulungile/okungalungile nokubheka phambili; ukubhekisa emuva kusebenza ku-PCRE/Python/Java kodwa AKUKHO ku-Go (RE2). Imodeli ikhetha ukwakha okulungile okulula futhi itshela uma izici azikwazi ukuthunyelwa.
Uma kucelwa ukufana "ama-letters" noma "igama lezinhlamvu" imodeli isebenzisa iziqu ezizizwayo ze-Unicode (`\p{L}`, `\p{N}` ku PCRE/Python/Java; `[\p{L}]` nge-`u` flag ku JavaScript) endaweni ye-ASCII-only edlulele `[a-zA-Z]`. Nquma "ASCII only" ku-prompt uma ufuna ukuziphatha okudlulele.
Imodeli iqondiswe ukuthi igweme ukubekezelelana okuncane okufana ne `(.+)+` okubangela i-ReDoS. Ku-Go (RE2) i-engine iqinisekisa isikhathi esihamba phambili ngakho lokhu akukwazi ukukwenziwa ngokuthuthukiswa. Ku-PCRE/JS/Python, hlola njalo izingeniso ezide ngemuva - chofoza ku-Regex101 nge-10,000-character string bese ubheka i-step counter.
ChatGPT (GPT-4) iphatha i-regex kahle kodwa ibiza i- $ 20 / mo futhi i-context ayi-regex-tuned. i-Free.ai's system prompt icindezela i-flavour ecacile + i-match / i-non-match test cases + i-complexity warnings. I-Qwen 3 Coder eholayo imahhala ngaphansi kwe-token pool yansuku zonke. I-premium GPT-5 itholakala nge-token ekhokhelwa.
Yebo - chofoza i-regex bese ubuza "ukuguqula le-Python regex ibe yi-Go RE2". Imodeli ibhala kabusha ngokusebenzisa kuphela izici ezixhasiwe ze-target flavor futhi itshela uma izici zingalingani (isibonelo, izixhumanisi ezimisiwe uma zihamba i-Python → Go).
Yebo - UTHENGA ku /v1/incoko/ nge-regex-specialist system prompt kanye nolwazi lwakho njengomehluko womyalezo womsebenzisi. Kubalulekile kumathuluzi akhiqiza ngokuzenzakalela i-regex kusuka kumsebenzisi ongeniswe (akukho kodwa-code form builders, log-parser configurators). Bona /api/.
Yebo - ikhodi eliyinhloko liqukethe imodeli emnyama NEMIQHULU yesilimi esifanele (`/imodeli/iflags` yeJavaScript, `r"imodeli"` yePython, ```imodeli``` yeGo). Chofoza Kopela bese ufaka ngqo emthonjeni wakho.
