In this video, reacting to a reader's comment, I explain how you can add your own regex to my re-search.py tool (without changing the code).

I create a file with name re-search.txt and content:

str-bang="[^"]+![^"]+"

This will add regurlar expression "[^"]+![^"]+" named str-bang to re-search's library:
