Hi all,

I am wondering if there is a quick and dirty way of displaying via  
“puts” the relative path name of files as required or loaded within the  
console. It would be useful for debugging. Presently I have a line at  
the top of my files something like:

puts “Loading somefile.rb…”

This has been invaluable for diagnosing most errors.

Obviously, in a dynamic language this seems silly. Somehow I know the  
ability to do this in a few lines of code is build straight into ruby.

Thanks much.  
Mario

Sure, it is a matter of aliasing:

```
 $ irb
 irb(main):001:0> def require_with_puts(filename) puts filename;

```

require\_without\_puts(filename); end  
=\> nil  
irb(main):002:0\> alias require\_without\_puts require  
=\> nil  
irb(main):003:0\> alias require require\_with\_puts  
=\> nil  
irb(main):004:0\> require ‘rubygems’
