Golang : Match strings by wildcard patterns with filepath.Match() function
Problem:
You want to match strings using the same wildcard patterns commonly used in Linux/Unix shells such as *.go
or *data[0-9]*
. How to do that?
Solution:
package main
import (
"fmt"
"path/filepath"
)
func main() {
filename := "start.txt"
pattern := "*art*"
matched, err := filepath.Match(pattern, filename)
if err != nil {
fmt.Println(err)
}
fmt.Println(matched)
//---------------------------------
pattern = "*fart*"
matched, err = filepath.Match(pattern, filename)
if err != nil {
fmt.Println(err)
}
fmt.Println(matched)
//---------------------------------
filename = "data123.csv"
pattern = "data[0-9]*"
matched, err = filepath.Match(pattern, filename)
if err != nil {
fmt.Println(err)
}
fmt.Println(matched)
}
Output :
true
false
true
NOTES: This example is for matching strings. For filenames in the current or specific directory. See this tutorial https://socketloop.com/tutorials/golang-use-wildcard-patterns-with-filepath-glob-example
It should work as well if you replace filepath.Match()
with path.Match()
