ok, then i'll answer it myself
I'm on OS X which has 'tail'
If you're on windows (why aren't you using flashdevelop?) you'll have to use cygwin or get fancy with the batch scripting.
Found this:
http://flash-focus.blogspot.com/2007/06 ... ow-in.htmlfollowed those instructions ... then in Eclipse added an External tool configuration:
Run >> External Tools >> External Tools Configurations
New Program
Location: /usr/bin/tail
Arguments: -f "/Users/MYUSER/Library/Preferences/Macromedia/Flash Player/Logs/flashlog.txt"
I wasn't able to point to the user Library via ~/Library -- maybe that's an eclipse shortcoming...
Launch that, and it appears as one of the running console logs, then you can run your build normally, ANT or what-have-you, and you'll still get the trace output without all the debug perspective stuff, and it's about a zillion times faster. yay!
seems like there ought to be console level configuration somewhere, but I'm no eclipse expert.
hope this helps someone else.
