markup2pdf converts markdown and textile to a pdf file.
The reason for this program is that often I've written text in markdown or textile and when somebody asked me about the text I did not have the tools ready to convert the text to pdf. You can test it here.
Install on heroku
$ git clone https://github.com/swerter/markup2pdf.git
$ cd markup2pdf/
$ bundle install
$ heroku create --stack cedar
$ git push heroku master
The project is based on Presto. The pdf conversation uses pdfkit, which is based on wkhtmltopdf.
