I'm not sure anyone but me even cares - but if anyone is looking to move an entire directory structure of templates without specifying each template individually - maybe this will help them too!

Dir["/your/path/to/your/templates/**/*"].each do |file|
    if (File.file?(file))
      filename = File.basename(file)
      newfilename = File.absolute_path(file).split("templates/")
      if (newfilename[1].rindex('/') != nil && newfilename[1].rindex('/') > 1)
          dirstocreate = newfilename[1][0, newfilename[1].rindex('/')]
         directory "/path/you/want/them/created/in/#{dirstocreate}"  do
             recursive true
             action :create
          end
      end 
      template "//path/you/want/them/created/in/#{newfilename[1]}" do
         local true
         source "#{file}"
      end
   end
end

seemed to work for me - hope this helps someone else!

Hey guys -

Thanks for the feed back!

I have this much working:

Dir["/some/path/to/templates/**/*"].each do |file|
    if (File.file?(file))
      filename = File.basename(file)
      template "/tmp/foo/#{filename}" do
         local true
         source "#{file}"
      end
   end
end

The only outstanding issue with this is the path is NOT maintained/preserved :-/

so if I have:

templates/subdir/textfile.txt

and the target location is:

/tmp/foo

I wind up with:

/tmp/foo/textfile.txt

when I really want

/tmp/foo/subdir/textfile.txt

I think I need to add in a directory resource....

You could use the ruby_block to generate (and store) an array of template paths to interact with, during convergence phase after the extraction.

The only issue is that the "each" loop as you have it will be run at compile-time.  So if you don't create the directory full of templates until convergence (eg: with Chef), that will be an empty array.  This is why Adam was using the "ruby_block" resource.

Of couse the ruby_block resource might have its own problems.  I don't know whether something like this will actually work (I think it won't)

ruby_block "process templates" do

  Directory["/srv/app/templates/**"].each do |filename|

    template filename do

      #stuff

    end

  end

end

Hmmm - ok, it's a bit clearer now, but this is an area I'm not familiar with.

Can't I do:

Directory["/path/to/templates/**"].each do |file|
  template /tmp/foo/file do
     local true
     source file
  end
end

??

I'm not sure how to reference the file variable in the actual template resource now tho...

Ack!

Something like this:

remote_file "/srv/app/deploy.zip" do
  source "http://example.com/deploy.zip"
end

execute "unzip /srv/app/deploy.zip"

ruby_block "process templates" do
  source <<-EOH
Directory["/srv/app/templates/**"].each do |file|
  ...
end
EOH
End

Should do the trick (where Š is fill in the blanks).
