words.list should be in the same directory as the .rb that''s calling
it. If that doesn''t work and using the absolute path doesn''t
work try
a relative path like ../../words.list if it''s in your rails_root. In
addition the following code might change things or not, I doubt it
will make it work but it''s a little prettier.
Try the following code:
File.open("words.list").each do |line|
# Do something with the var line
end
or a slightly different approach
words = File.readlines("words.list")
I''m not sure why but IO and foreach seem to be pretty rarely used. I
think they''ve gone out of style. Maybe just because File is easier to
get the gist of when dealing with Files and IO when doing io streams
like tcp/ip.
Hope that helps. If you don''t already have it in your bookmarks try to
find _why''s Pickaxe on google; it''s an old copy of the Ruby
manual
with links to the sections. Got me through a lot of pain :)
Sincerely,
Chuck Vose
