I was looking at the short intro to GCD in Matt's book 'Macruby - The
Definitive Guide'
I have macruby 0.8 and I come across an immediate problem
macirb --simple-prompt
>> require 'dispatch'
LoadError: no such file to load -- dispatch
However, it knows about Dispatch:
macirb --simple-prompt
>> @queue = Dispatch::Queue.new('a-queue-name')
=> a-queue-name
but it doesn't know about Job:
macirb --simple-prompt
>> job = Dispatch::Job.new { slow_operation }
NameError: uninitialized constant Dispatch::Job
and, finally, the line on p24, 'To see the available concurrent
enumerable methods'
macruby -rdispatch -e "puts [].methods.grep(/^p_/)"
no such file to load -- dispatch (LoadError)
which, I suppose, just reiterates the first point.
Is there an 'official' site where I can post queries regarding this
book?
