Genex package for Go

Easy and efficient package to expand any given regex into all the possible strings that it can match.

This is the code that powers namegrep.

Usage

package main

import (
    "fmt"
    "regexp/syntax"

    "github.com/alixaxel/genex"
)

func main() {
    charset, _ := syntax.Parse(`[0-9a-z]`, syntax.Perl)

    if input, err := syntax.Parse(`(foo|bar|baz){1,2}\d`, syntax.Perl); err == nil {
        fmt.Println("Count:", genex.Count(input, charset, 3))

        genex.Generate(input, charset, 3, func(output string) {
            fmt.Println("[*]", output)
        })
    }
}
