Forked from drewish brilliant take on Cal Newport's Time-Block Planner. It generates a PDF with a week's worth of A4 pages. You can take a look at a sample and see what you think.
Assuming you've got Ruby and Bundler installed you can just run:
git clone git@github.com:jlorenzetti/planner.git
cd planner
bundle install
It assumes you want to generate pages for the next week so there are no options:
bundle exec planner.rb
Probably only works on a Mac since it hardcodes the font path.
