I’m not sure if this is either the simplest or the best solution, but when I want to see the log while Rack is running, I launch the app as usual and then run a command such as
tail -f -n10000 <Rack user folder>/log.txt
in a separate terminal window, where the 10000 is an arbitrary number that’s large enough to ensure that I can scroll back to see the beginning of the file.
It doesn’t look like using -d to get terminal logging is fit for a standard install. So the option then is to simply tail the log file output as said above, possibly augmented with a | grep -F MySlug to only see specific module output.
tx! yeah, for what I need to do (find a crazy bug that’s arm only), I just delete the log, run normally, harvest the log, edit. It’s working well enough.
