Loading .rb files in IRb

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:inrequire’
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

puts $:

Some default enhancements/settings for IRB, based on

http://wiki.rubygarden.org/Ruby/page/show/Irb/TipsAndTricks

Require RubyGems by default.

require ‘rubygems’
require ‘wirble’

Activate auto-completion.

require ‘irb/completion’

Use the simple prompt if possible.

IRB.conf[:PROMPT_MODE] = :SIMPLE if IRB.conf[:PROMPT_MODE] == :DEFAULT

Setup permanent history.

HISTFILE = “~/.irb_history”
MAXHISTSIZE = 100
begin
histfile = File::expand_path(HISTFILE)
if File::exists?(histfile)
lines = IO::readlines(histfile).collect { |line| line.chomp }
puts “Read #{lines.nitems} saved history commands from
‘#{histfile}’.” if $VERBOSE
Readline::HISTORY.push(*lines)
else
puts “History file ‘#{histfile}’ was empty or non-existant.” if
$VERBOSE
end
Kernel::at_exit do
lines = Readline::HISTORY.to_a.reverse.uniq.reverse
lines = lines[-MAXHISTSIZE, MAXHISTSIZE] if lines.nitems >
MAXHISTSIZE
puts “Saving #{lines.length} history lines to ‘#{histfile}’.” if
$VERBOSE
File::open(histfile, File::WRONLY|File::CREAT|File::TRUNC) { |io|
io.puts lines.join("\n") }
end
end

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:
