Whatsapp chat statistics

Little python script to analyze and export your Whatsapp chats from the Whatsapps chat database. It creates some beautiful plots, an HTML and a LaTeX version of the chat history.
Printing HTML files to PDFs can be a problem for large chat histories. With the LaTeX version, you can create a beautiful (printable) PDF version of all your messages (with all emojis). (see below)
With the built-in export functionality you can only export the last 10,000 (with images) or 40,000 (without images) messages. Using the database you can analyze your complete chat history.

1. Export of your message database:

1. Option: Your phone is rooted. Just copy the file msgstore.db from the directory /data/data/app/com.whatsapp/databases to your computer.
2. Option: You have a Huawei Phone. In this case, follow these instructions.

There may be other possibilities to get your message database like decrypting the sd-card backup, but they will not be discussed here.

2. Creating chat statistics

Download or clone the repository and run

foo@bar:~$ python whatsapp-stats.py --phone_number '+49 170 00000000' 'C:\PathToFile\msgstore.db' --mode tex

Available modes are normal (default, no html or LaTeX generation), html (generates html) and tex (generates tex). They can also be combined: html|tex.

See all available options with

foo@bar:~$ python whatsapp-stats.py --help

LaTeX version to PDF

With the generated .tex file you can create a beautiful PDF version of your chat history which includes all emojis. Printing HTML files to a PDF with a normal computer is only possible for a small number of pages. PDF generation by LaTeX is much more efficient. Follow these steps to create your PDF file:

1. If not already done: Download and install a LaTeX distribution (which comes with the lualatex package, probably all common distributions do that)
2. If you want to display your emojis correctly, copy the contents of this coloremoji repository to your tex-output folder (probably output/tex).
   Pay attention, that the directory coloremoji and the file coloremoji.sty are in the same directory as your chat.tex.
3. Outcomment \usepackage{coloremoji} in line 15 of your chat.tex.
4. Navigate a terminal to the directory of your chat.tex and run

   foo@bar:~$ lualatex chat.tex

   You can use other LaTeX compiler but for me lualatex worked the best for non-ASCII characters and very large chat histories.
