Regex101 / Regexr / Debuggex ndezve EXPLAINER zvinhu - iwe unonyora regex, ivo vanoiratidza. Free.ai ndeimwe GENERATOR - iwe unotaura zvaunoda muChirungu, inonyora regex. Usashandisa Free.ai yekutanga draft, wozoisa muRegex101 kuti uzviongorore nedata rako rakanaka. Kubatanidzwa kwebasa rinochengeta mazuva pamusoro pekunyora-maoko regexes kubva kune cheat sheet.
PCRE (yakajairika mu PHP, Perl, uye mamwe maLinux maturusi). JavaScript (browser + Node, hapana kutsvaka-kumberi mu Safari ≤16.3). Python re (inofananidza nePCRE, hapana kutsvaka-kumberi).

Chokwadza imwe yaunofarira rurimi rwaunofarira - zvinhu senge kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / kutsvaka-kumberi / ku
Kutenda mashoko: hapana regex inoenzanisa chero real-world input zvakakwana. Email validation chete ane 6,425-character "RFC 5322 compliant" regex hapana munhu anoshandisa. Free.ai anotarisana 99% kesi yekushandisa iwe unotaura uye anozivisa nezve edge cases munyaya (eg, "iyi inoenzanisa example.co.uk asi kwete example.museum"). Dai nguva dzose bvunzo pamusoro real data pamberi kutumira kugadzirwa.
Yeah - pedza regex mubhokisi remashoko rakabva pa "explain: " (e.g., `explain: ^(?=.*[A-Z])(?=.*\d).{8,}$`) uye chirongwa chinoparadza chero chinhu chinofananidza. Usashandisa /code/explain/ kuti uwane ruzivo rwakawanda nezvechirongwa.
Yeah - kana zvachose zvatsigirwa neyakasarudzwa flavor. PCRE/Python/JS inobvumira kuongorora zvakaipa/zvakanaka uye kuongorora zvakapfuura; backreferences inoita basa muPCRE/Python/Java asi HAINA kuita basa muGo (RE2). The model picks the simplest correct construct and warns when a feature is not portable.
Pakati apambwa kuti afanane ne "letters" kana "word characters" iyo model inoshandisa Unicode-aware classes (`\p{L}`, `\p{N}` muPCRE/Python/Java; `[\p{L}]` ne`u` flag muJavaScript) panzvimbo pekare ASCII-only `[a-zA-Z]`. Nzira yekuti uite izvi ndeyokuti utore "ASCII only" muprompt.
Model inodzidziswa kuti irambe ichidzivirira 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) handles regex well but costs $20/mo and the context isn't regex-tuned. Free.ai's system prompt forces explicit flavor + match/non-match test cases + complexity warnings. Self-hosted Qwen 3 Coder is free under the daily token pool. For unusually weird patterns, premium GPT-5 is available with paid tokens.
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.
