Ho appena trovato un'espressione regolare estremamente lunga (6000+ caratteri) per una convalida di e-mail WordPress. Questo mi ha fatto pensare, qual è il più lungo che tu abbia mai visto che viene utilizzato in un ambiente di produzione.Qual è l'espressione regolare più lunga che hai visto
A correct email address validation regex.
6.343 caratteri.

"Questa espressione regolare convaliderà solo gli indirizzi che hanno ricevuto commenti spogliati e sostituiti con spazi bianchi (operazione eseguita dal modulo)." –
Questo è esattamente lo stesso di Jason. O forse Jason's è uguale al tuo? – Ponkadoodle
L'espressione regolare per convalidare gli indirizzi e-mail (possibilmente multiple in to:, cc: e bcc: forma) (da RFC 822) è abbastanza robusto; sicuramente la più lunga espressione regolare non banale che ho visto. Sfortunatamente, sembra che ci siano molti siti là fuori su Internet che non usano questa espressione regolare o una validazione equivalente poiché ho incontrato troppi siti che non accettano [email protected] come un indirizzo email valido.

Per evitare confusione: questo non è così complesso da convalidare un singolo indirizzo email, ha bisogno di questa complessità per convalidare i blocchi di indirizzi, ad es. nella parte di destinazione dell'intestazione dell'email (A :, cc :, ecc.). Questi blocchi possono contenere newline, spazi bianchi, ecc. –
