recursive output of a directory and its sub-directories

[Alexander Fleck]

hi,
I want to walk through a directory recursively.

I have the follwing code:

'
#!/usr/bin/env ruby

def search
Dir.foreach(".\\") { |x|
if File.directory?(x)
search
else
open(x) do |file|
file.each { |l| puts l}
end
puts x
end
}
end

search
'

I get a 'stack level too deep'-error. What does that mean and how can I
avoid it?

thanks,
Alex.

Hi,

You reach this limit because you are stacking forever: your search
method has no argument, so no recursion occures. You have to pass the
path of the subdirectory to search into to the search method.

Another (better) way is to use the "find" standard library of Ruby.

require "find"

Find.find(".") do |f|
puts f
end

(I haven't tested this code but it should work).
It will do the work for you.

Regards,
Come

thanks,

I now use the 'find' module.
