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)
	}
}
