> 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)
|
||
|
--------|---------|-------|--------------
|
||
|
`[a-z][!a-x]*cat*[h][!b]*eyes*` | `my cat has very bright eyes` | `true` | 432
|
||
|
`[a-z][!a-x]*cat*[h][!b]*eyes*` | `my dog has very bright eyes` | `false` | 199
|
||
|
`https://*.google.*` | `https://account.google.com` | `true` | 96
|
||
|
`https://*.google.*` | `https://google.com` | `false` | 66
|
||
|
`{https://*.google.*,*yandex.*,*yahoo.*,*mail.ru}` | `http://yahoo.com` | `true` | 163
|
||
|
`{https://*.google.*,*yandex.*,*yahoo.*,*mail.ru}` | `http://google.com` | `false` | 197
|
||
|
`{https://*gobwas.com,http://exclude.gobwas.com}` | `https://safe.gobwas.com` | `true` | 22
|
||
|
`{https://*gobwas.com,http://exclude.gobwas.com}` | `http://safe.gobwas.com` | `false` | 24
|
||
|
`abc*` | `abcdef` | `true` | 8.15
|
||
|
`abc*` | `af` | `false` | 5.68
|
||
|
`*def` | `abcdef` | `true` | 8.84
|
||

`*def` | `af` | `false` | 5.74
|

|
`ab*ef` | `abcdef` | `true` | 15.2
|
||
|
`ab*ef` | `af` | `false` | 10.4
|
||
|
|
||
|
The same things with `regexp` package:
|
||
|
|
||
|
Pattern | Fixture | Match | Speed (ns/op)
|
||
|
--------|---------|-------|--------------
|

|
`^https:\/\/.*\.google\..*$` | `https://account.google.com` | `true` | 1205
|
||
|
`^https:\/\/.*\.google\..*$` | `https://google.com` | `false` | 767
|
||
|
`^(https:\/\/.*\.google\..*|.*yandex\..*|.*yahoo\..*|.*mail\.ru)$` | `http://yahoo.com` | `true` | 1435

## Syntax
|
||
|
|
||
|
Syntax is inspired by [standard wildcards](http://tldp.org/LDP/GNU-Linux-Tools-Summary/html/x11655.htm),
|
||
|
except that `**` is aka super-asterisk, that do not sensitive for separators.
