Method: OptParseBuilder.build_bundle

Defined in:

lib/opt_parse_builder.rb

.build_bundle {|bundler| ... } ⇒ Object

Build a bundle of arguments that can be added to a parser together. Yields an ArgumentBundleBuilder.

This is useful when you have a group of arguments that go together:

bundle = OptParseBuilder.build_bundle do |args|
  args.add do |arg|
    arg.key :x
    op.on "-x", Integer, "X coordinate"
  end
  args.add do |arg|
    arg.key :y
    op.on "-y", Integer, "Y coordinate"
  end
end

arg_parser = OptParseBuilder.build_parser do |args|
  args.add bundle
end

Raises BuildError if the argument cannot be built or added.

This is most useful when you are building a related suite of programs that share some command-line arguments in common. Most of the time you will just add the arguments using the block form of OptParseBuilder#add.

Yields:

• (bundler)

  bundler = ArgumentBundleBuilder.new
  yield bundler
  bundler.argument
