Go implementation of Regexp::Assemble

This is a Go language package for joining regular expressions into a regular expression which matches all strings that any of the arguments matches.

package main

import (
	"fmt"
	"log"

	"github.com/itchyny/rassemble-go"
)

func main() {
	xs, err := rassemble.Join([]string{"abc", "ab", "acbd", "abe"})
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(xs) // a(?:b[ce]?|cbd)
}

A command line tool is also provided.
