Go Zip Example

An example of how to zip a directory in Go.

• Utilizes filepath.Walk to traverse a directory (or single file)
• Handles each of
  • Files (deflated, compressed)
  • Directories (empty, not compressed)
  • Symlinks (not compressed)
  • Skips irregular files (pipes, sockets, devices, chars)
• Names zip file after the name of the directory
• Trims path prefix

git clone https://git.coolaj86.com/coolaj86/go-examples.git
pushd go-examples/zip

go run . path/to/whatever

wrote whatever.zip

Separates concerns into functions for readability:

• func main()
• func Zip(w io.Writer, src string, trim string) error
  • zipOne
    • zipDirectory
    • zipFile
    • zipSymlink
