Allow copying local directories instead of using symlinks

[laverya]

Sometimes, you really do just want a copy of the files, and not a symlink. For example, when you'll be editing the files that have just been go-gettered - as we do in replicatedhq/ship. Edits being reflected in the upstream files would be extremely unexpected behavior, and so true copies are needed.

Hello,

I have the same issue. I'm trying to create a full copy of the source folder to the destination path:

client := &getter.Client{
	Src:  sourceUrl,
	Dst:  destination,
	Pwd:  pwd,
	Mode: getter.ClientModeDir,
	Detectors: []getter.Detector{
		new(getter.FileDetector),
	},
	Getters: map[string]getter.Getter{
		"file": &getter.FileGetter{
			Copy: true,
		},
	},
}

err := client.Get()

But even with the Copy of the FileGetter to true I only have a symlink.

I worked around it with a quick fix here, creating a custom getter:

use is here:

I used a ready made folder copy algorithm, but ideally, it should be included in go-getter itself.
