You may have tried to pass args to ruby via  bat file before, like

ruby -e “puts %*” # print out all the arguments

turns out this doesn’t work if you pass in an argument with backslashes, though [like \a\b\a -- it interpolates them as escaped strings]

To overcome this, create go.bat

ruby some_file.rb %*

then use ARGV within that file–it will no longer be escaped.

Enjoy.

you could do this by using set_trace_func (or it’s C wrappers)

require 'faster_rubygems'
require 'event_hook'

class Demo < EventHook   def self.process(*args)      # args => [64, #, :initialize, Exception]
   begin
     if args[1].is_a? Exception
       puts args.inspect
     end
   rescue
     # fantastically, this check fails within rails at times
   end
  end
end

Demo.start_hook

or you can just run ruby -d [$DEBUG = true] and it will do it for you automatically.

appears that by default the command line parameters [ARGV] are frozen strings. go figure.

You can still do funky things with ARGV, though.

ARGV.map!{|name| name.dup} # now they’re not frozen

ARGV.shift

etc
