Subject: Re: Syntax for gem list file when hosting own rubygems repository

Well...documentation...no, but its a good idea to document.  Here is what
you need to do in a nutshell (what kind of nut...):

You need webserver/virtual host where you can have two files in the root:

www.whatever.com/yaml
www.whatever.com/yaml.Z

Then you place the gem files in a subdirectory:

www.whatever.com/gems/whatever.gem

If you have a set of gem files that you want to host and you want to build
the yaml and yaml.Z file use the following code:

require 'optparse'
require 'rubygems'
require 'zlib'

Gem.manage_gems

class Indexer

  def initialize(directory)
    @directory = directory
  end

  def gem_file_list
    Dir.glob(File.join(@directory, "*.gem"))
  end

  def build_index
    File.open(File.join(@directory, "yaml"), "w") do |file|
      file.puts "--- !ruby/object:Gem::Cache"
      file.puts "gems:"
      gem_file_list.each do |gemfile|
        spec = Gem::Format.from_file_by_path(gemfile).spec
        file.puts "  #{spec.full_name}: #{spec.to_yaml.gsub(/\n/, "\n
")[4..-1]}"
      end
    end
    build_compressed_index
  end
  
  def build_compressed_index
    File.open(File.join(@directory, "yaml.Z"), "w") do |file|
      file.write(Zlib::Deflate.deflate(File.read(File.join(@directory,
"yaml"))))
    end
  end
end

##
#
# Build index
#
#

Indexer.new(".").build_index

_______

If that code is to hard to extract from the email, let me know and I will
post it.  Note that the directory that you pass in to the indexer is
location of the gem files.  You need to chmod the yaml and yaml.Z files so
they are readable from a web client, yada yada yada.

To use it you then do:

gem install whatever.gem --source http://www.whatever.com

Hope that helps,

Rich
