Regex Generator — FAQ
Kutaura kuti chii iwe uchida kuti zvienzanise muChirungu chikuru ("US zip codes", "sezvo URLs kunze localhost", "kuzvimirira parentheses kusvika kudzika 3") uye regazve a zvakajeka regex ne flavor-aware syntax (PCRE, JavaScript, Python re, Go regexp, POSIX), nhanho-ne-nzira mashoko, uye a bvunzo panel kuratidzwa chokwadi zvinyorwa kuti zvienzanise vs. haasi kusangana.
Regex101 / Regexr / Debuggex ndezve EXPLAINER zviwanikwa — iwe unonyora regex, ivo vanoiratidza. Free.ai ndeye GENERATOR — iwe unotaura zvaunoda muChirungu, inonyora regex. Usashandisa Free.ai yekutanga draft, wozoisa muRegex101 kuti uone kuti ndezvipi zvinoitika kune yako data. Kubatanidzwa kwebasa rinochengetedza mazuva anopfuura ekudhinda regexes kubva pa cheat sheet.
PCRE (yakajairika mu PHP, Perl, mamwe maLinux maturusi). JavaScript (browser + Node, hapana kutsvaka-kumberi mu Safari ≤16.3). Python re (inosvika paku PCRE, hapana kutsvaka-kumberi). Go regexp (RE2 — hapana kutsvaka-kumberi, hapana kutsvaka-kumberi, asi nguva-yekutevedzera inogaranwa kuti ichengeteke). POSIX BRE/ERE (grep, sed pasina -E). Chova neimwe yaunofarira rurimi rwaunosarudza — zvinhu sekutsvaka-kumberi / kutsvaka-kumberi / mapoka ane zita hazvina kuiswa kune ese marudzi.
Kutenda mashoko: hapana regex inoenzanisa chero real-world input zvakakwana. Email validation chete ine 6,425-character "RFC 5322 compliant" regex hapana munhu anoshandisa. Free.ai inotarisa pa 99% yenyaya yekushandiswa iwe unotaura uye unozivisa nezvezvinozivikanwa edge cases muruzivo (e.g., "iyi inoenzanisa example.co.uk asi kwete example.museum").
Yeah — pedza regex mubhokisi remashoko rakabva pa "explain: " (e.g., `explain: ^(?=.*[A-Z])(?=.*\d).{8,}$`) uye chirongwa chinoparadza ma tokens ese uye chinokuudza kuti chii chacho chakafanana. Usashandisa /code/explain/ kuti uwane ruzivo rwakawanda nezvekodhi.
Yeah — kana iyo yakasarudzwa flavor ichitsigira izvi. PCRE/Python/JS inobvumira kuongorora zvakaipa/zvakanaka uye kuongorora zvakapfuura; backreferences inoita basa muPCRE/Python/Java asi HAII muGo (RE2).
Pakati pekubvunza kuti uenzanise "mazita" kana "mavara emazwi" mufananidzo unoshandisa marudzi anozivikanwa neUnicode (`\p{L}`, `\p{N}` muPCRE/Python/Java; `[\p{L}]` ne`u` flag muJavaScript) panzvimbo pekare ASCII-only `[a-zA-Z]`. Nzira yekutaura "ASCII chete" mubvunzo kana uchida kutevedzera hunhu hwekare.
Model inodzidziswa kuti idzivirire kuiswa kwekwantifiers se `(.+)+` izvo zvinokonzera ReDoS. For Go (RE2) the engine guarantees linear time so this is impossible by construction. For PCRE/JS/Python, always test long inputs after — paste into Regex101 with a 10,000-char string and watch the steps counter.
ChatGPT (GPT-4) anodzora regex zvakanaka asi zvinoda $20/mo uye mamiriro haasi regex-tuned. Free.ai's system prompt inomanikidza zvakajeka flavor + match/non-match test cases + complexity warnings. Self-hosted Qwen 3 Coder ndeyemahara pasi pezuva nezuva token pool.
Yeah — pedza regex uye taura "convert this Python regex to Go RE2". The model rewrites it using only the target flavor's supported features and warns when a feature has no equivalent (e.g., backreferences when going Python → Go).
Yeah — POST to /v1/chat/ with a regex-specialist system prompt and your description as the user message. Useful for tools that auto-generate regex from user input (no-code form builders, log-parser configurators). See /api/.
Yeah — primary code block ine raw pattern WITH the language-appropriate delimiters (`/pattern/flags` for JavaScript, `r"pattern"` for Python, `` `pattern` `` for Go).Click Copy and paste directly into your source.
