Move your stashes from one repo to another

---

This was useful for me when we created a new branch for a new major release, but were still working on our current version as well. I cloned our repo again and kept the new project on our new branch, but also wanted to get my stashes there.

Download your stashes

git stash show -p > patch

You'll have to specify your stash and name your file whatevery you want. Do this for as all your stashes, and you'll have patch files in your pwd.

  pattern = /^\d+\.\d+\.\d+(\-(dev|beta|rc\d+))?$/
  raise "Tried to set invalid version: #{version}".red unless version =~ pattern
end

def correct_version version
  ver, flag = version.split '-'
  v = ver.split '.'
  (0..2).each do |n|
    v[n] = v[n].to_i
