Functions
func CopyDirContents
func CopyDirContents(src, dst string) error
CopyDirContents recursively copies contents of src to dst.
Example
package main
import (
"log"
"go.astrophena.name/gen/fileutil"
)
func main() {
if err := fileutil.CopyDirContents("phryne", "fisher"); err != nil {
log.Fatal(err)
}
}
func CopyFile
func CopyFile(src, dst string) error
CopyFile copies the file src to dst.
Example
package main
import (
"log"
"go.astrophena.name/gen/fileutil"
)
func main() {
if err := fileutil.CopyFile("/etc/hostname", "/tmp/hostname"); err != nil {
log.Fatal(err)
}
}
func Exists
func Exists(path string) bool
Exists returns true if a file or directory does exist and false
otherwise.
Example
package main
import (
"fmt"
"go.astrophena.name/gen/fileutil"
)
func main() {
if fileutil.Exists("example") {
fmt.Println("example exists")
} else {
fmt.Println("no example!")
}
}
func Files
func Files(dir string, exts ...string) (files []string, err error)
Files returns a slice of files in the directory dir recursively
with extensions exts, or an error. If no file extensions are
supplied, all files are returned.
Example
package main
import (
"fmt"
"path/filepath"
"go.astrophena.name/gen/fileutil"
)
func main() {
dir := filepath.Join("testdata/files")
fmt.Println(fileutil.Files(dir))
}
func Mkdir
func Mkdir(dir string) error
Mkdir creates the directory, if it does not already exist. It also
creates parent directories as needed.
Example
package main
import (
"log"
"go.astrophena.name/gen/fileutil"
)
func main() {
if err := fileutil.Mkdir("example"); err != nil {
log.Fatal(err)
}
}
