simple-glob

Go Simple Globbing Library.

This repository was forked from https://github.com/gobwas/glob, but with some simplifications. Only * is supported as a wildcard to match any string other than a delimiter.

Install

    go get github.com/gopherlib/simple-glob

Example

package main

import "github.com/gopherlib/simple-glob"

func main() {
	var g glob.Glob

	// create simple glob
	g = glob.MustCompile("*.github.com")
	g.Match("api.github.com") // true

	// create new glob with set of delimiters as ["."]
	g = glob.MustCompile("api.*.com", '.')
	g.Match("api.github.com") // true
	g.Match("api.gi.hub.com") // false
	
	// create new glob without set of delimiters as ["."]
	g = glob.MustCompile("api.*.com")
	g.Match("api.github.com") // true
	g.Match("api.gi.hub.com") // true
}

Performance

This library is created for compile-once patterns. This means, that compilation could take time, but strings matching is done faster, than in case when always parsing template.

If you do not use compiled glob.Glob object, and do g := glob.MustCompile(pattern); g.Match(...) every time, then your code will be much slower.

Run go test -bench=. from source root to see the benchmarks:
