Search through a JSON dump of Trello cards. Trello does not currently offer a way to search through card contents (description, comments) - only their titles. If you export a board as a JSON dump, you can use this script to search through everything.
I do not intend to maintain this script. I needed it to search for something at work and I thought it might help someone else. If it does, cool. Feel free to modify it and do whatever you want with it (see the license).
./grep_trello.py [options] "your search term" <the_dump.json
Options include -i (for case insensitive search) and -r (for Perl-compatible regular expression search).
