Mixin module providing HTML generation methods.

For example,

cgi.a("http://www.example.com") { "Example" }
  # => "<A HREF=\"http://www.example.com\">Example</A>"

Modules Html3, Html4, etc., contain more basic HTML-generation methods (#title, #h1, etc.).

See class CGI for a detailed example.

The Observable module extended to DRb. See Observable for details.

This module has all methods of FileUtils module, but it outputs messages before acting. This equates to passing the :verbose flag to methods in FileUtils.

Configuration options for dumping YAML.

Using the Pull Parser

This API is experimental, and subject to change.

parser = PullParser.new( "<a>text<b att='val'/>txet</a>" )
while parser.has_next?
  res = parser.next
  puts res[1]['att'] if res.start_tag? and res[0] == 'b'
end

See the PullEvent class for information on the content of the results. The data is identical to the arguments passed for the various events to the StreamListener API.

Notice that:

parser = PullParser.new( "<a>BAD DOCUMENT" )
while parser.has_next?
  res = parser.next
  raise res[1] if res.error?
end

Nat Price gave me some good ideas for the API.

You don’t want to use this class. Really. Use XPath, which is a wrapper for this class. Believe me. You don’t want to poke around in here. There is strange, dark magic at work in this code. Beware. Go back! Go back while you still can!

This is the JSON parser implemented as a C extension. It can be configured to be used by setting

JSON.parser = JSON::Ext::Parser

with the method parser= in JSON.
