# glob.[go](https://golang.org)
[![GoDoc][godoc-image]][godoc-url] [![Build Status][travis-image]][travis-url]
> Go Globbing Library.
## Install
```shell
go get github.com/gobwas/glob
```
## Example
```go
package main
import "github.com/gobwas/glob"
func main() {
var g glob.Glob
// create simple glob
g = glob.MustCompile("*.github.com")
g.Match("api.github.com") // true
// quote meta characters and then create simple glob
g = glob.MustCompile(glob.QuoteMeta("*.github.com"))
g.Match("*.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 with set of delimiters as ["."]
// but now with super wildcard
g = glob.MustCompile("api.**.com", '.')
g.Match("api.github.com") // true
g.Match("api.gi.hub.com") // true
// create glob with single symbol wildcard
g = glob.MustCompile("?at")
g.Match("cat") // true
g.Match("fat") // true
g.Match("at") // false
// create glob with single symbol wildcard and delimiters ['f']
g = glob.MustCompile("?at", 'f')
g.Match("cat") // true
g.Match("fat") // false
g.Match("at") // false
// create glob with character-list matchers
g = glob.MustCompile("[abc]at")
g.Match("cat") // true
g.Match("bat") // true
g.Match("fat") // false
g.Match("at") // false
// create glob with character-list matchers
g = glob.MustCompile("[!abc]at")
g.Match("cat") // false
g.Match("bat") // false
g.Match("fat") // true
g.Match("at") // false
// create glob with character-range matchers
g = glob.MustCompile("[a-c]at")
g.Match("cat") // true
g.Match("bat") // true
g.Match("fat") // false
g.Match("at") // false
// create glob with character-range matchers
g = glob.MustCompile("[!a-c]at")
g.Match("cat") // false
g.Match("bat") // false
g.Match("fat") // true
g.Match("at") // false
// create glob with pattern-alternatives list
g = glob.MustCompile("{cat,bat,[fr]at}")
g.Match("cat") // true
g.Match("bat") // true
g.Match("fat") // true
g.Match("rat") // true
g.Match("at") // false
g.Match("zat") // false
}
```
## 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 will not use compiled `glob.Glob` object, and do `g := glob.MustCompile(pattern); g.Match(...)` every time, then your code will be much more slower.
Run `go test -bench=.` from source root to see the benchmarks:
Pattern | Fixture | Match | Speed (ns/op)
--------|---------|-------|--------------

except that `**` is aka super-asterisk, that do not sensitive for separators.
