display only script messages with mitmdump

It would be nice if there is a built-in way to only display script messages with mitmdump. Currently it looks like there is no feature like this, the --flow-detail 0 option displays other messages as well so a workaround is to use grep to display the message we want to catch from a script, for example mitmdump --flow-detail 0 -s script.py | grep MESSAGE. The disadvantage is that it does filtering with unnecessary processing through a third-party tool like grep.

Can you combine --quiet with print() inside your script? mitmdump itself should then not print anything and all you get is the output of your script. Worked well for me so far.

@mhils Thanks. In a future version, would it be possible to have an option to use ctx.log.info() instead of print() to display only script messages with mitmdump? This would be useful in case we have a script that is already using ctx.log.info() but we don’t want to change the code to use print() or if we want to use the event log of mitmproxy also.
