This is a dirty little Ruby program to export a Habari blog to markdown format. I used it to avoid installing PHP on a small VPS in order to run a tiny blog of ~2000 posts.

The program makes a few assumptions about your setup, and this conditions what you should expect to get from it.

• It will connect to a MariaDB/MySQL database,
• fetch all of its posts and:

  • dump one file per published post in the out directory ;

  • use a filename like YYYY-MM-DD-post-slug.md where YYYY-MM-DD are the year, month, and month day when a particular post was published ;

  • and format a post header with:

    title: The original post title
    author: The author's username
    

This process can be pretty specific, and if it does not fit your setup, feel free to file an issue or, better, send a pull-request. ;)

• Ruby >= 1.9
• Python >= 2.x
