|
> Simple 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.New("*.github.com")
|
|
g.Match("api.github.com") // true
|
|
|
|
// create new glob with set of delimiters as ["."]
|
|
g = glob.New("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.New("api.**.com", ".")
|
|
g.Match("api.github.com") // true
|
|
g.Match("api.gi.hub.com") // true
|
|
|
|
// create glob with single symbol wildcard
|
|
g = glob.New("?at")
|
|
g.Match("cat") // true
|
|
g.Match("fat") // true
|
|
g.Match("at") // false
|
|
|
|
// create glob with single symbol wildcard and delimiters ["f"]
|
|
g = glob.New("?at", "f")
|
|
g.Match("cat") // true
|
|
g.Match("fat") // false
|
|
g.Match("at") // false
|
|
}
|
|
|
|
```
|
|
|
|
## Performance
|
|
|
|
In comparison with [go-glob](https://github.com/ryanuber/go-glob), it is ~2.7x faster (on my personal Mac),
|
|
because my impl compiles patterns for future usage. If you will not use compiled `glob.Glob` object,
|
|
and do `g := glob.New(pattern); g.Match(...)` every time, then your code will be about ~3x slower.
