我想在运行时使用参数列表创建一些Gems:my_app --help。
就像所有的宝石(耙子,铁轨等)。
示例:
Usage:
rails new APP_PATH [options]
Options:
-J, [--skip-prototype] # Skip Prototype files
-T, [--skip-test-unit] # Skip Test::Unit files
[--dev] # Setup the application with Gemfile pointing to your Rails checkout
-G, [--skip-git] # Skip Git ignores and keeps
-b, [--builder=BUILDER] # Path to an application builder (can be a filesystem path or URL)
-m, [--template=TEMPLATE] # Path to an application template (can be a filesystem path or URL)
[--edge] # Setup the application with Gemfile pointing to Rails repository
[--skip-gemfile] # Don't create a Gemfile
-d, [--database=DATABASE] # Preconfigure for selected database (options:
通过这种方式,我可以通过以下方式使用它:
gem install my_gem
my_gem --help
my_gem delete files file1.jpg file2.jpg
my_gem update
etc...
是否有某种宝石框架或是否需要从头开始?

有很多选择(haaaa ......)
标准的是Ruby的stdlib:http://ruby-doc.org/stdlib/libdoc/optparse/rdoc/index.html
Rails使用Thor,可能更适合您的需求。 http://rubygems.org/gems/thor
