LogWatchr on xruby for my real world performance articles

[pat eyler]

I thought I'd try to get LogWatchR running on the 0.3.2 release of XRuby
so I could start including it in my 'Real World Performance' series. Alas,
it fails right off the bat. Any clues about where I should start?

$ java -jar xruby-0.3.2.jar -c logwatcher.rb
$ java -jar xruby-0.3.2.jar logwatcher.jar < 20_minute_log
Exception in thread "main" line 1:3: unexpected char: 0x3

Hey pat,
 
Thank you for reporting the issue. The problem is xruby is not following c ruby correctly with command line processing, it tried to run '20_minute_log' as a ruby program.

Recently all xruby team members, including myself, have been busy with other stuffs and made little progress in recent two months. We may not be able to fix the problems of running logwatcher.rb promptly. I am sorry about that.
