问题
I am trying to take a chunk of bytes and compress them using the archive/zip
package in Go. However, I can't understand it at all. Are there any examples of how it could be done and is there any explanation of that cryptic package?

Thanks to jamessan I did find the example (which doesn't exactly catch your eye).
Here is what I come up with as the result:
func (this *Zipnik) zipData() {
// Create a buffer to write our archive to.
fmt.Println("we are in the zipData function")
buf := new(bytes.Buffer)
// Create a new zip archive.
zipWriter := zip.NewWriter(buf)
// Add some files to the archive.
var files = []struct {
Name, Body string
}{
{"readme.txt", "This archive contains some text files."},
{"gopher.txt", "Gopher names:\nGeorge\nGeoffrey\nGonzo"},
{"todo.txt", "Get animal handling licence.\nWrite more examples."},
}
for _, file := range files {
zipFile, err := zipWriter.Create(file.Name)
if err != nil {
fmt.Println(err)
}
_, err = zipFile.Write([]byte(file.Body))
if err != nil {
fmt.Println(err)
}
}
// Make sure to check the error on Close.
err := zipWriter.Close()
if err != nil {
fmt.Println(err)
}
//write the zipped file to the disk
ioutil.WriteFile("Hello.zip", buf.Bytes(), 0777)
}
I hope you find it useful :)
