Directory search

ruby-talk
1

I am writing a program to go in all the folders, then in to there folders....

def dirsearch (coming_in) #declare coming_in is the directory to be searched
print "\n\n\n",coming_in," line 2 \n\n\n" #testing
Dir.chdir(coming_in) #change to the directory
mainloc = Dir.getwd #new base
file = Array.new

print "\n\n\n",mainloc," line 7 \n\n\n" #testing

loc = Dir.open(mainloc) #open the folder
loc.each {|x| file.push(x) } #get the folders and files

dir = Array.new
count = file.size #amounts

if count==0 then break end#check if there are any files
print "-----------list------------",count,"--"
while count>0
if(!(file[count-1].include? ?.)) #for windows assume that file has an
extension and no folders have a .
reform = mainloc +'/'+ file[count-1] # create list of folders
print reform
dir.push(reform)
end
count-=1
end
print "\n"
if !(dir.size==0) then #check if any folders to go in to
many = dir.size-1;
while many>0
print dir[many],"loop at 28th\n"
if(!(dir[many].nil?))then #having a problem with nil folders? any help?
dirsearch(dir[many])#call function with new directory
end
many-=1
end
end
end

dirsearch("c:") # light the candle

i am using SciTE in windows XP. It just seems to be cutting out after
about 5 runs of the function. Am i writing over the same variables?

Hi Stephen,

It looks like all you do is print out the directory name. This might be
a bit closer to what you're looking for:

def recurse(path, max_depth = 5)
  Dir::entries(path).select do |file|
    file !~ /^\./ && test(?d, File::join(path, file))
  end.each do |dir|
    puts File::join(path, dir)
    recurse(File::join(path, dir), max_depth - 1) if max_depth > 0
  end
end

Hope this helps...

You might like to read
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/20172

and the answers to that one. What's done there is to add a walker method to class DIR - which as the name implies walks through the directory and uses a passed block to do something with the current path name.

I currently have code like this

class Dir
   def walk ( prefix = nil, &walker )
     e = self.entries
     e.delete "."
     e.delete ".."

     e.collect!{ | x | File.join( prefix, x ) } if prefix

     if block_given?
       e.each { | x |
         if File.directory?( x )
           Dir.new( x ).walk( x, &walker )
         end
         yield x
       }
     end
     nil
   end
end

Dir.new( "E:/" ).walk( "E:/" ) { | p | puts p if p =~ /ruby/ }

But note that this code won't work on XP if there are any directories of files which can only be read with administrator rights: You'll run into a 'permission denied (Errno::EACCES)'...
I'll have to work on that.

Happy rubying
