Project Overview

Module github.com/shoenig/regexplus provides a package with extra functions for managing regular expressions, beyond what the standard library regexp provides.

Getting Started

The regexplus package can be installed by running

$ go get github.com/shoenig/regexplus

Example usage

re := regexp.MustCompile(`(?P<foo>[a-z]+)-(?P<bar>[0-9]+)`)
m := FindNamedSubmatches(re, "abc-123")
// m == Map{"foo":"abc", "bar":"123"}

Overview

Package regexplus provides additional convenience functions over regexp.

Index

• type Map
  • func FindNamedSubmatches(re *regexp.Regexp, s string) Map

Types

type Map

type Map map[string]string

A Map represents the key-value pairs generated by a regexp named group string matching. The keys are the names of named groups and the values are the matched strings.

func FindNamedSubmatches

func FindNamedSubmatches(re *regexp.Regexp, s string) Map

FindNamedSubmatches uses re to find named submatches of s, and returns a Map from keys (names of groups) to values (matches).

Example:

re := regexp.MustCompile(`(?P<foo>[a-z]+)-(?P<bar>[0-9]+)`)
m := FindNamedSubmatches(re, "abc-123")
m == Map{"foo":"abc", "bar":"123"}
