> 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
|
|
|
|
// 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 | Operations | Speed (ns/op)
