A brutish migration script from Tumblr posts to Jekyll-friendly markdown files.

tumblr_to_jekyll.sh

# Change this to your blog URL...
export TUMBLR_URL="http://zeke.tumblr.com"

# As of this writing, jekyll and jekyll-import are busted. :(
gem uninstall jekyll -aIx

# Install an old version of jekyll that includes a migration script
gem install jekyll -v 0.11.2

# Install a python package that converts HTML to Markdown
sudo pip install html2text

# Get them posts (various sources suggest that a "markdown" argument can be passed 
# to the process function, but it didn't work for me)
ruby -rubygems -e 'require "jekyll/migrators/tumblr"; Jekyll::Tumblr.process(ENV["TUMBLR_URL"])'

# Convert HTML files to Markdown
for file in _posts/tumblr/*.html; do html2text "$file" > "${file/.html/.md}"; rm "$file"; done;
