wordpress2tumblr.rb

# Export your Wordpress posts to Tumblr (also allows to delete some.)
# Author: Alexandre Solleiro <alex@webcracy.org> 
# How-to:
# 1. Export your Wordpress posts (http://en.blog.wordpress.com/2006/06/12/xml-import-export/)
# 2. Edit the information below to match your settings
# 3. To import, type "ruby wordpress2tumblr.rb --run" in the command line 
# 4. To delete some posts, type "ruby wordpress2tumblr.rb --delete 1,2,3,4" where 1,2,3,4 are post numbers. (Be careful not to use spaces between IDs)

# Edit these
WP_EXPORT_PATH = "./wordpress.2009-09-14.xml"   # path to the Wordpress Export file
TUMBLR_BLOG_URL = "http://yourblog.tumblr.com"  # without a trailing slash!
TUMBLR_EMAIL = "email@domain.com"               # the email of your Tumblr account
TUMBLR_PASSWORD = "password"                    # your Tumblr account password
TUMBLR_DRAFT = 1                                # 1 saves your posts as drafts on Tumblr; 0 publishes them

# Dependencies: the following gems
require 'rubygems'
require 'open-uri'
require 'rest_client'
require 'hpricot'
require 'json'
require 'time'

# No need to touch here
TUMBLR_WRITE_API = "http://www.tumblr.com/api/write"
TUMBLR_DELETE_API = "http://www.tumblr.com/api/delete"

# This was borrowed from http://choonkeat.svnrepository.com/svn/rails-plugins/misc/hpricot/rss.rb
# It trims the CDATA[] declaration in WP's RSS output

  text.gsub!(/\<\!\[CDATA\[(.*)\]\]\>/m, '\1') if text =~ /<\!\[CDATA\[/ && text =~ /\]\]>/
