Overview

Package pcre is a set of functions that implement regular expression pattern matching using the same syntax and semantics as Perl, with just a few differences. Some features that appeared in Python and PCRE before they appeared in Perl are also available using the Python syntax, there is some support for one or two .NET and Oniguruma syntax items, and there is an option for requesting some minor changes that give better JavaScript compatibility.

Types

type Option

type Option int

type Regexp

type Regexp struct {
	// contains filtered or unexported fields
}

func Compile

func Compile(pattern string, options Option, tables Table) (*Regexp, error)

func MustCompile

func MustCompile(s string, options Option, tables Table) *Regexp

MustCompile is like Compile but panics if the expression cannot be parsed. It simplifies safe initialization of global variables holding compiled regular expressions.

func (*Regexp) Close

func (re *Regexp) Close()

func (*Regexp) Exec

func (re *Regexp) Exec(subject []byte, options Option, out []int32) (int, error)

func (*Regexp) FindIndex

func (re *Regexp) FindIndex(b []byte, options Option) (loc []int32, err error)

func (*Regexp) Fullinfo

func (re *Regexp) Fullinfo(what int32) (int32, error)

func (*Regexp) ReplaceAll

func (re *Regexp) ReplaceAll(b, repl []byte, options Option) (r []byte, err error)

type Table

type Table struct{ crt.Intptr }
