In the following example copied from
https://github.com/mjijackson/citrus/blob/master/lib/citrus/grammars/...

require 'ipv4address'                 # (1)
require 'ipv6address'

grammar IPAddress
  include IPv4Address
  include IPv6Address

  rule IPaddress
    IPv4address | IPv6address
  end
end

Is the line (1) should be written like

   Citrus.require 'ipv4address'

Do I miss anything?

Hi Ken,

The thing you need to remember is that although .citrus files look like
Ruby, they're not really Ruby. They're actually a custom little language
that looks a lot like Ruby. You can see the implementation for a `require`
statement inside a .citrus file here:

https://github.com/mjijackson/citrus/blob/master/lib/citrus/file.rb#L...

It simply tries to use Kernel.require first, and falls back to
Citrus.require if that fails. If both fail, the original LoadError is
raised.

     # File lib/citrus.rb, line 99
 99:   def self.require(file, options={})
100:     file += '.citrus' unless /\.citrus$/ === file
101:     found = nil
102:
103:     paths = ['']
104:     paths += $LOAD_PATH unless Pathname.new(file).absolute?

If you look at line 103, it seems the paths is initialized with an
empty value,
then the "require" will run a unnecessary loop actually because paths
will be
the "" + the current $LOAD_PATH, I think this may be corrected like
below,

  paths = []

or just remove the line 103, as $LOAD_PATH is an Array, so we can just
change 104 to,

  paths = $LOAD_PATH unless Pathname.new(file).absolute?

The initialization of a new array to paths seems to be not needed.
