Eval defaulting to binding

ruby-talk

Hi,

sometimes (or many times), i put some debugging lines in my code. something like,

C:\family\ruby>cat -n debugger.rb
     1 #-----------------
     2 # debugger.rb
     3 #-----------------
     4
     5 DEBUG_MACRO_1='puts "FILE: #{__FILE__} LINE: #{__LINE__}, ID: #{[self
.to_s, self.object_id]}"'
     6
     7 def debugger bin
     8 eval(DEBUG_MACRO_1,bin)
     9 end

C:\family\ruby>cat -n test5.rb
     1 #------------
     2 # test5.rb
     3 #------------
     4
     5 require 'debugger.rb'
     6
     7 class A
     8 def a
     9 debugger binding #<-- this is my debugging line
    10 end
    11 end
    12
    13 A.new.a

C:\family\ruby>ruby test5.rb
FILE: test5.rb LINE: 9, ID: #<A:0x28804bc>21234270

I'd like to pass the "binding" argument as default on the debugger line, so that i do not have to state it; ie, just "debugger" instead of "debugger binding". Is that possible? tips, pls :slight_smile:

kind regards -botp

No, but there is no need for eval here. This is as good:

class Object
   def debug
     md = caller[0].match /\A(.+):(\d+):confused: || [nil, "unknown", "unknown"]
     puts "FILE: #{md[1]} LINE: #{md[2]}, ID: #{object_id}, OBJECT: #{inspect}"
   end
end

Kind regards

# class Object
# def debug
# md = caller[0].match /\A(.+):(\d+):confused: || [nil, "unknown", "unknown"]
# puts "FILE: #{md[1]} LINE: #{md[2]}, ID: #{object_id}, OBJECT: #{inspect}"
# end
# end

robert, as always, thanks for the tip.
