Use this to automatically scrape all of your saved Instapaper articles locally as HTML and PDF files. I originally wrote this to read my saved documents on my reMarkable tablet. Instapaper does not have an option to export all my stuff as PDF as far as I could tell (the built-in options only export a subset).
You will need to have the following packages installed:
Configure your username and password, then run the script. It will go through all articles shown on your home page and download the copy Instapaper has stored into a folder called output as HTML file and convert it into a PDF. You can customize the look by updating the included styles.css file. Any errors will be reported and logged to failed.txt. Errors might be due to parsing errors on Instapaper's side or due to PDF conversion issues.
