Hugo Estrada's House of Wonder

I needed to erase SVN folders from a directory. Ironically, I needed to do this so that I could put them back, in a cleaner format, into the repository.

Here is the script that I wrote in ruby to do this:

#! usr/bin/env ruby
 
def delete_dir(dir_name)
 d = Dir.new(dir_name)
 d.each{ |file|
   if !(file == "." || file == "..") then
     if File.directory?(file) then
       delete_dir(file)
     else
        File.delete(file)
     end  
   end
 }
 Dir.delete(dir_name)
end
 
 
def clean_svn(dir_name)
d = Dir.new(dir_name)
d.each {|file_name|
if !(file_name == "." || file_name == "..") then
  if file_name == ".svn" then
    delete_dir(file_name)
  end
  if File.directory?(file_name) then
    clean_svn(file)
  end
end
}
end
 
file = ARGV[0]
clean_svn(file)

I have two comments on the script. First, there seems to be a nice FileUtils method that does delete a folder recursively. I learned about it after I finished writing this, so delete_dir is unnecessary.

Second, the limitation of this script is that it is using recursion, and that stack must be shallow, since ruby is not an optimized functional language. So if there are too many directories within directories, it will choke at some point.

But for my purposes, this worked well.
