ruby - Directory walk call method when directory is reached -

-

trying write script search through directory , sub-directories specific files. know how directory or directories come call method.

this have tried , failed: 

def display_directory(path) list = dir[path+'/*']  return if list.length == 0  list.each |f|         if file.directory? f #is directory?     if file.directory?('config')       puts "this config folder"     end     printf "%-50s %s\n", f, "is directory:".upcase.rjust(25)   else     printf "%-50s %s\n", f, "is not directory:".upcase.rjust(25)   end  end end   start = file.join("**") puts "processing directory\n\n".upcase.center(30) display_directory start

this want happen. 

        app app/controllers app/helpers app/mailers app/models app/models/bugzilla app/models/security app/views app/views/auth app/views/calendar app/views/layouts app/views/step app/views/step_mailer app/views/suggestion app/views/suggestion_mailer app/views/task app/views/user bin -------------------------------------- config <----------(call method foo) config/environments config/initializers config/locales -------------------------------------- db db/bugzilla db/migrate db/security lib lib/tasks log public public/images public/javascripts public/stylesheets script script/performance script/process -------------------------- test <---------(call method foobar) test/fixtures test/fixtures/mailer test/functional test/integration test/performance test/unit -------------------------- vendor vendor/plugins

instead

if file.directory?('config')

try

if f.path.include?('config')

but work every directory have config on name. can put larger substring make better match.

also, idiomatic in ruby use do..end multiline blocks , {..} single line.
