golang: cross platform path.Dir

Question

I\'d like to use path.Dir() on Unix and Windows with a platform specific directory. Please take a look at the code:

package main

import (
    \"fmt

I see where the "problem" is. This discussion at golang-nuts gave me the hint, that path.Dir() always uses / and filepath.Dir() is the function to be used for platform dependent manipulation.

package main

import (
    "fmt"
    "path/filepath"
)

func main() {
    fmt.Println(`filepath.Dir("a/b/c"): `, filepath.Dir("a/b/c"))
    fmt.Println(`filepath.Dir("c:\foo\bar.exe"): `, filepath.Dir(`c:\foo\bar.exe`))
}

on windows:

filepath.Dir("a/b/c"):  a\b
filepath.Dir("c:\foo\bar.exe"):  c:\foo
