Hi Alan, Ouch, you may have found a bug… can you file a ticket? I will look into it for the upcoming release. Thanks, Laurent On Jan 12, 2011, at 1:03 AM, Alan Skipp wrote:
Hi everyone, Below is a reduction of a problem I've noticed when using 'enumerateObjectsUsingBlock' from inside a proc. The line which causes trouble is: [1,2,3].enumerateObjectsUsingBlock( Proc.new { |o, i, s| puts "inner enumeration #{o}" } )
If this line is replaced with: [1,2,3].each { |e| puts "inner enumeration #{e}" } Then the code behaves as expected.
framework 'Foundation'
proc = Proc.new do |arg| [1,2,3].enumerateObjectsUsingBlock( Proc.new { |o, i, s| puts "inner enumeration #{o}" } ) puts arg.upcase end
%w[a b c].enumerateObjectsUsingBlock( Proc.new do |obj, idx, stop| proc.call(obj) end )
The output is as follows:
inner enumeration 1 inner enumeration 2 inner enumeration 3 A inner enumeration b inner enumeration c
The output I would expect is this:
inner enumeration 1 inner enumeration 2 inner enumeration 3 A inner enumeration 1 inner enumeration 2 inner enumeration 3 B inner enumeration 1 inner enumeration 2 inner enumeration 3 C
