open files in other directories

[Matthew Margolis]

I am trying to figure out how to open up a text file in a subdirectory
of my programs main directory. The file I want is in the subdirectory
labeled text. I get a "Permission denied - text/" message when
attempting to run the code found below.

campershash = Hash.new
Dir.entries("text").each do |textfilename|
campershash["#{textfilename.chop.chop.chop.chop}"] =
File.open("text/" + "#{textfilename}") { |f| f.gets(nil) }
end

The Dir.entries call works finer but on the next line when I go to open
up each text file in the text directory I run into problems. I am
running the program on windows XP with administrator privileges so I am
unclear as to why I am having permission issues.

Any and all help is greatly appreciated,
Matthew Margolis

You're probably trying to open a directory (. and .. in 'text/'). Try
one of the two examples below:

campershash =3D {}
Dir.entries("text").each do |textfilename|
# Don't know why you're using four chop's - but I've replaced them
# with 'strip' to make the example more readable.
campershash[textfilename.strip] =3D=20
File.read(File.join("text", textfilename)) if File.file?(textfilena=
me)
end

or

campershash =3D {}
Dir["text/*"].each do |f|
campershash[f.strip] =3D File.read(f)
end
