Export your Octopress files to Ghost

This is a very rough script to export your octopress files to Ghost. You will still need to check your data but it will give you a head start. Feel free to fork and optimize the script for your purpose.

The following should be considered:

  1. You need to execute the script in the source/_posts directory
  2. You need to manually copy all the images to /var/www/ghost/content/images
  3. Images with external URLs are not handled
  4. Blockquotes have their issues
  5. Lists are not exported correctly

For the content I had to migrate it was a good compromise between automation and manual checking and corrections.

Hope this helps anyone ;-)
