regexmap

Very simple and straight forward function to take a regex and, for all given named matches, populate a map.

Installation

$ go get github.com/nikole-dunixi/regexmap

Usage

Suppose you want to extract named groups from a string using a regular expression:

input := `Nikole Dunixi`
pattern := `^(?P<first>\w+)\s+(?P<last>\w+)$`
// err ignored for brevity
matches, _ := regexmap.MatchPattern(pattern, input)
fmt.Println(matches["first"], matches["last"])

// Output:
// Nikole Dunixi
