"require" with many files

ruby-talk
1

Hi, is there any preferred way to load/require all the fiels in a directory?
For example, my main file does:

  require "header.rb"

and file "header.rb" must load all the related files contained in
"headers/" directory. I do the following in "header.rb":

  headers_path = File.dirname(__FILE__) + '/headers'
  Dir.chdir(headers_path)
  Dir["*.rb"].each do |file|
      require "#{headers_path}/#{file}"
  end

Is it enought ok or can it receive some Ruby's magic? XD

Thanks for any suggestion.

You do use Ruby magic here ;-). The only thing I would suggest is that if you do not have to set the current directory to headers_path for some other reason, use this variation:

  Dir[File.join(File.dirname(__FILE__), 'headers', "*.rb")].each do |file|
      require file
  end

glob = File.join( File.dirname(__FILE__), 'headers', '*.rb' )

Dir.glob(glob){|lib| require lib}

is a bit shorter...

we can deny everything, except that we have the possibility of being better. simply reflect on that.

If you say

$: << theDirectory

then you can just require the files by name, I believe... m.

I seem to recall proposals for allowing something like "require header/
*" ala Java's import (maybe I brought it up myself?) but I can't
remember what the arguments against it were.

Dir.glob(glob){|lib| require lib}

The problem is that I need to load before some specifi files because have
modules that others files require:

headers_path = File.dirname(__FILE__) + '/headers'
Dir.chdir(headers_path)

require "#{headers_path}/header.rb"
require "#{headers_path}/modules.rb"

Dir["hdr_*.rb"].each do |file|
  require "#{headers_path}/#{file}"
end

But ok, thanks a lot for all your suggestions :slight_smile:
