WhatsApp conversations can be exported from the app in a .txt format.
However, the .txt files are not easy to read. This tool takes the .txt
file, parses it, generates a HTML page with CSS styling,
and compiles the page into a pdf using wkhtmltopdf.
This project is built with stack. Make sure you have stack and wkhtmltopdf
installed. The application is run with stack run [path to chat.txt].
Note
The app requires the version of wkhtmltopdf with the Qt patch.
On Arch, you need to install the wkhtmltopdf-static package from AUR.
WhatsApp might change the format of the .txt file in the future,
in which case you might have to fiddle with the parse functions in Lib.hs.
