[chef] Re: Re: Re: Re: Re: Bulk expansion of templates

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).
