Text.Regex.PCRE2

Contents

Wrap, for =~ and =~~, types and constants

Description

The Text.Regex.PCRE2 module provides a backend for regular expressions. If you import this along with other backends, then you should do so with qualified imports, perhaps renamed for convenience.

This library uses the newer libpcre2, which supports UTF8-encoded strings by default.

The regular expression can be provided as a ByteString. The regular expression and search string are passed as CStringLens and may contain NUL bytes and do not need to end in a NUL byte. ByteStrings are searched in place (via unsafeUseAsCStringLen).

A String will be converted into a CStringLen for processing. Doing this repeatedly will be very inefficient.

The Text.Regex.PCRE2.String, Text.Regex.PCRE2.ByteString, and Text.Regex.PCRE2.Wrap modules provide both the high-level interface exported by this module and medium- and low-level interfaces that return errors using Either structures.
