multithreading - User interrupt in Ruby infinite loop (multiple classes)? -

i found question similar mine solution worked me when wrote in 1 simple script. wrote second simple example sort of simulating i'm trying do, , seemed still work.

my simulation was:

class   def looper(&block)     thread.new       loop         exit if gets.chomp == 'q'       end     end     loop       block.call     end   end end  class b <   def looper     super       puts 'howddyyyy b'     end   end end 

this works fine, exiting when press q<enter>. however, when tried implement actual project, fails work. i'll post code method in question in child class, parent class literally same example above.

def looper   super     if obj = object.first(:process_status => status_unprocessed)       puts "[object ##{obj.id}] processing..."       puts "-" * 60        obj.set_failed       if @obj.process(obj)         obj.set_processed       end        puts "-" * 60       puts "[object ##{obj.id}] finished!"       puts       puts     else       sleep 10     end   end end 

so, reason, doesn't work. put puts new thread (listening q), , seems output puts before every loop of block.call. maybe isn't able key, mean, maybe timeframe in have enter q<enter> way small? i'm not sure, why i'm asking advice here. other guess has methods called within method (process, or possible sequel calls database) blocking other thread(s)?

i'm new threading, have no clue.

okay, everybody. feel little stupid typing up, came solution not 5 minutes later (and 1 had overlooked here on stack overflow).

for facing similar issue in future, ended doing (in parent class):

def looper(&block)   interrupted = false   trap("int") { interrupted = true }   until interrupted     block.call   end   exit end 

this manages achieve trying do.

thanks reading!
