Relative Path in GO
Matches relative file paths (./, ../, or path/to/file).
Try it in the GO tester →Pattern
regexGO
^(\.{1,2}\/)?([^\/\0]+\/)*[^\/\0]+$Go (RE2) code
goGo
package main
import (
"fmt"
"regexp"
)
func main() {
re := regexp.MustCompile(`^(\.{1,2}\/)?([^\/\0]+\/)*[^\/\0]+$`)
input := `./src/index.ts`
for _, match := range re.FindAllString(input, -1) {
fmt.Println(match)
}
}Uses `regexp.MustCompile` (panics on bad patterns at startup) and `FindAllString` for all matches.
How the pattern works
`^(\.{1,2}\/)?` optionally matches `./` or `../` prefix. `([^\/\0]+\/)*` matches zero or more directory segments. `[^\/\0]+$` matches the final file segment.
