Loading .rb files in IRb

ruby-talk
1

Hi..

I am trying to get IRb to load a file. I am running a fresh install of
Mac OS X Leopard and I have updated my gems and RubyGems. Below is the
Class file ( From the Pickaxe and saved under /Users/gudni/Song.rb ) and
the results from my previous attempts.

Attempt 1:

load '/Users/gudni/Song.rb'

--> LoadError: no such file to load -- /Users/gudni/Song.rb
  from (irb):3:in `load'
  from (irb):3

Attempt 2:

require '/Users/gudni/Song.rb'

-->LoadError: no such file to load -- /Users/gudni/Song.rb
  from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:27:in
`gem_original_require'
  from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:27:in `require'
  from (irb):5

I can't get it to work. According to the pickaxe it should be enough to
give the full path to the file, but it doesn't seem to work for me. Any
help would be much appreciated :smiley:

P.S. Happy holidays :smiley:

class Song
  def initialize(name, artist, duration)
    @name = name
    @artist = artist
    @duration = duration
  end

  def to_s
    "Song: #@name--#@artist (#@duration)"
  end
end

Content of my $:

puts $:

/Library/Ruby/Gems/1.8/gems/wirble-0.1.2/bin
/Library/Ruby/Gems/1.8/gems/wirble-0.1.2/.
/Library/Ruby/Site/1.8

.

and my irbrc

    File::open(histfile, File::WRONLY|File::CREAT|File::TRUNC) { |io|
io.puts lines.join("\n") }

It really should work. Note that path and file names are probably
case-sensitive, though. You can try to use Dir.glob to list the
contents of the directory :

Dir.glob('/home/fred/*.rb')

=> ["/home/fred/toto.rb", "/home/fred/main.rb"]

Thanks for the Reply Fred...

I figured out that TextMate added a whitespace after .rb !

Dir.glob('/Users/gudni/*')
=> ["/Users/gudni/Desktop", "/Users/gudni/Documents",
"/Users/gudni/Downloads", "/Users/gudni/KaraokeSong.rb ",
"/Users/gudni/Library", "/Users/gudni/Movies", "/Users/gudni/Music",
"/Users/gudni/Pictures", "/Users/gudni/Public", "/Users/gudni/Sites",
"/Users/gudni/Song.rb ", "/Users/gudni/test.rb "]

That is whack :smiley:

Anyway thanks for pointing me in the right direction :smiley:
