The pcre2 vocab implements a simple binding for libpcre2, enabling rich regular expression support for Factor applications.

Precompiling and optimizing a regular expression:

<pcre2> ( expr -- pcre2 )

Once compiled, a pcre2 is a Deterministic resource disposal disposable and should be released with dispose (or used inside with-disposal).

Searching, testing, and splitting:

findall ( subject obj -- matches )

matches? ( subject obj -- ? )

split ( subject obj -- strings )

Querying a compiled pattern and the library:

has-option? ( pcre2 option -- ? )

version ( -- f )

Examples



Notes
Regular expressions are by default utf8 and unicode aware.
