Logging when files are required/loaded

ruby-talk
1

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'
     rubygems
     rubygems/rubygems_version
     rubygems/defaults
     thread
     thread.so
     rbconfig
     rbconfig/datadir
     rubygems/exceptions
     rubygems
     rubygems/version
     rubygems
     rubygems/requirement
     rubygems/version
     rubygems/requirement
     rubygems/dependency
     rubygems
     rubygems/gem_path_searcher
     rubygems
     rubygems/source_index
     rubygems
     rubygems/user_interaction
     rubygems/specification
     rubygems
     rubygems/version
     rubygems/platform
     rubygems
     rubygems/platform
     rubygems/builder
     rubygems/custom_require
     rubygems
     => true
