Examples
Extracting an ISO
package main
import (
"log"
"github.com/kdomanski/iso9660/util"
)
func main() {
f, err := os.Open("/home/user/myImage.iso")
if err != nil {
log.Fatalf("failed to open file: %s", err)
}
defer f.Close()
if err = util.ExtractImageToDirectory(f, "/home/user/target_dir"); err != nil {
log.Fatalf("failed to extract image: %s", err)
}
}
Creating an ISO
package main
import (
"log"
"os"
"github.com/kdomanski/iso9660"
)
func main() {
writer, err := iso9660.NewWriter()
if err != nil {
log.Fatalf("failed to create writer: %s", err)
}
defer writer.Cleanup()
f, err := os.Open("/home/user/myFile.txt")
if err != nil {
log.Fatalf("failed to open file: %s", err)
}
defer f.Close()
err = writer.AddFile(f, "folder/MYFILE.TXT")
if err != nil {
log.Fatalf("failed to add file: %s", err)
}
outputFile, err := os.OpenFile("/home/user/output.iso", os.O_WRONLY | os.O_TRUNC | os.O_CREATE, 0644)
if err != nil {
log.Fatalf("failed to create file: %s", err)
}
err = writer.WriteTo(outputFile, "testvol")
if err != nil {
log.Fatalf("failed to write ISO image: %s", err)
}
err = outputFile.Close()
if err != nil {
log.Fatalf("failed to close output file: %s", err)
}
}
Recursively create an ISO image from the given directories
package main
import (
"fmt"
"log"
"os"
"path/filepath"
"strings"
"github.com/kdomanski/iso9660"
)
func main() {
writer, err := iso9660.NewWriter()
if err != nil {
log.Fatalf("failed to create writer: %s", err)
}
defer writer.Cleanup()
isoFile, err := os.OpenFile("C:/output.iso", os.O_WRONLY|os.O_TRUNC|os.O_CREATE, 0644)
if err != nil {
log.Fatalf("failed to create file: %s", err)
}
defer isoFile.Close()
prefix := "F:\\" // the prefix to remove in the output iso file
sourceFolders := []string{"F:\\test1", "F:\\test2"} // the given directories to create an ISO file from
for _, folderName := range sourceFolders {
folderPath := strings.Join([]string{prefix, folderName}, "/")
walk_err := filepath.Walk(folderPath, func(path string, info os.FileInfo, err error) error {
if err != nil {
log.Fatalf("walk: %s", err)
return err
}
if info.IsDir() {
return nil
}
outputPath := strings.TrimPrefix(path, prefix) // remove the source drive name
fmt.Printf("Adding file: %s\n", outputPath)
fileToAdd, err := os.Open(path)
if err != nil {
log.Fatalf("failed to open file: %s", err)
}
defer fileToAdd.Close()
err = writer.AddFile(fileToAdd, outputPath)
if err != nil {
log.Fatalf("failed to add file: %s", err)
}
return nil
})
if walk_err != nil {
log.Fatalf("%s", walk_err)
}
}
err = writer.WriteTo(isoFile, "Test")
if err != nil {
log.Fatalf("failed to write ISO image: %s", err)
}
}
