Signal Group User Activity

"How active is each user in the signal groups I'm in?"

This project generates a spreadsheet that looks like this:

	Alice	Bob	...
Neighborhod Chat	1	5	...
Roomate Chat	12	0	...
...	...	...	...

Each cell is the total message count for a user in a chat.

The goal is to afford distributed collection of group participation metadata from a community that uses disparate signal groups. No one member of the community is a member of every signal group, so we need to make use of multiple users' signal data.

I personally would not at all feel comfortable sending someone my decrypted signal database, so I implemented this as a dockerized python command line tool that runs locally. It generates a simple csv file that's easily inspectable before sharing.

Usage

The following command will build the necessary docker image, then run it against the signal config directory you point it to, and dump the output to ./output/table.csv:

$ ./run.sh -c ~/.config/Signal

Adding -f will filter the groups under consideration to only those listed in config/chat_list.txt

$ ./run.sh -c ~/.config/Signal -f

You might want to run the command once without filtering, then paste the chat name column from the spreadsheet into config/chat_list.txt and narrow down to only the ones you care about and run it again with -f.
