Golang Regular Expressions for Humans

This module is inspired in a similar project for javascript.

Example:

import (
	. "github.com/dakerfp/re"
)

re := Regex(
	Group("dividend", Digits),
	Then("/"),
	Group("divisor", Digits),
)

m = re.FindSubmatch("4/3")
fmt.Println(m[1]) // > 4
fmt.Println(m[2]) // > 3

the equivalent regexp would be:

regexp.MustCompile("(\\d+)/(\\d+)")

which is far more cryptic.

Another good example is the following regex (limited) to parse URLs:

import . "github.com/dakerfp/re"

re := re.Regex(
	StartOfLine,
	Then("http"),
	Maybe("s"),
	Then("://"),
	Maybe("www"),
	AtLeastOne(AnythingBut(' ')),
	EndOfLine,
)

which corresponds to

regexp.MustCompile("^http[s]?://(www)?[^\\ ]+$"),
