If you want to do globbing, include subdirectories and want to have relative paths. I would look at Pathname. You can, for example, generate relative paths via #relative_path_from:
irb(main):025:0> Pathname("/var/log/foo").relative_path_from(Pathname("/var"))
=> #<Pathname:log/foo>
irb(main):026:0> Pathname("/var/log/foo").relative_path_from(Pathname("/var")).to_s
=> "log/foo"
Pathname has also a method #find which yields Pathname instances to the block and can be used for things like this.
Kind regards

In the program Im making I need to read some wma files into a variable
and I did like this:songs = Dir.glob("C:\\Users\\Public\\Music\\Sample Music\\*.wma")
Note that this is NOT the wrong directory, I've copy pasted it from the
map itself and also the files are wma and nothing else. My programming
teacher has no idea why this dosnt work and the other ppl I've talked
with dosnt know either. Most said something like "aside from a simple
mistake like wrong directory/extension, I don't know what could be going
wrong." So now this forum is my last resort, why on earth dosnt this
work?!The only way I could get it to work is to use the example at class Dir - RDoc Documentation and create a directory variable such as: lfiles=Files.join("C:", "Users", "Public", "Music", "Sample Music", "*.wma") and then use a=Dir.glob(lfiles).
The only problem with that approach is that the entire path is added to each file. I don't know if this is a concern or not.Further experimenting found two other solutions. The first is to use:
a=Dir.glob("C:/Users/Public/Music/Sample Music/*.wma") which has the same "problem" as my first solution.
A better solution may be to use Dir.chdir to change to the directory and then use Dir.glob to extract the file names. This has the advantage of not including the path in front of each file name.chdir is not thread safe, it changes the pwd which is global to the process. Here's an alternative:
d = Dir.new("/tmp") # use fwd slashes even on windows
d.grep(/\.wma$/)This should give you an array of filenames in the dir.
Is there a way to expand this to include subdirectories like .glob allows? .grep doesn't appear to work on the string created by File.join.
