#403: rescue block executed if exception raised in previous iteration -------------------------------+-------------------------------------------- Reporter: pwilson@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: MacRuby 0.5 Component: MacRuby | Keywords: -------------------------------+-------------------------------------------- If a begin/rescue block is inside an iterator and the block raises an exception on the first iteration but calls return on the second iteration, the return is ignored and the rescue block ran a second time. Here is an example: {{{ def main [1,2].each do |iter| puts "Starting iteration #{iter}" begin if iter == 1 raise StandardError end puts " Successful iteration #{iter}" return true rescue StandardError puts " Failed iteration #{iter}" next end end return false end puts main }}} In Ruby 1.8.7, the main method returns true, but in the Oct 24 nightly build of MacRuby, it returns false with this output: {{{ Starting iteration 1 Failed iteration 1 Starting iteration 2 Successful iteration 2 Failed iteration 2 false }}} Note that on the second iteration, both the Successful and Failed log messages get printed. -- Ticket URL: <http://www.macruby.org/trac/ticket/403> MacRuby <http://macruby.org/>

I'm back from vacation and wrote a very simple tutorial: MacRuby tips: create a Cocoa file/folder browser in a few lines of code: http://bit.ly/1VuxBZ It looks like it's time for me to move my tutorials http://merbist.com/category/macruby/ to MacRuby's recipes. Anyone feels like contributing more examples/tutorials? - Matt

Drawing in Custom Views
by John-Paul Bader 26 Oct '09

26 Oct '09

Hey, just saw the previous question regarding an example from the Cocoa book. I'm currently trying play with custom views and paths. Right now I'm trying the Example from page 240 »Drawing with NSBezierPath« but I can't get the path to draw. I uploaded the xcode project onto http://smyck.org/drawing.zip The Controller is quite simple http://pastie.textmate.org/private/kafqjbqoml48otms0ddcqq Something is not right but I don't know what - maybe one of you more experienced cocoa coders can help me out. Kind regards, John
