JSSupported

JavaScript / ECMAScript

Browser-native RegExp. Default if you don't pick.

PYSupported

Python (re)

CPython stdlib `re`. Unicode-aware `\w` and `\d` by default.

GOSupported

Go (RE2)

Linear-time matching. No backreferences or lookarounds.

Pattern

regexengine-agnostic
rediss?:\/\/(?:([^:@\s]+)(?::([^@\s]*))?@)?([^:\/\s]+)(?::(\d+))?(?:\/(\d+))?   (flags: g)

Raw source: rediss?:\/\/(?:([^:@\s]+)(?::([^@\s]*))?@)?([^:\/\s]+)(?::(\d+))?(?:\/(\d+))?

How it works

rediss?:\/\/ matches either scheme. The optional auth group captures user and optional password. The host group captures the hostname. (?::(\d+))? optionally captures the port. (?:\/(\d+))? optionally captures the database index (Redis databases are numeric).
