A Resolver::Specification contains a subset of the information contained in a Gem::Specification. Only the information necessary for dependency resolution in the resolver is included.

A VendorSpecification represents a gem that has been unpacked into a project and is being loaded through a gem dependencies file through the path: option.

The StaticSet is a static set of gem specifications used for testing only. It is available by requiring Gem::TestCase.

Basic Authentication for WEBrick

Use this class to add basic authentication to a WEBrick servlet.

Here is an example of how to set up a BasicAuth:

config = { :Realm => 'BasicAuth example realm' }

htpasswd = WEBrick::HTTPAuth::Htpasswd.new 'my_password_file'
htpasswd.set_passwd config[:Realm], 'username', 'password'
htpasswd.flush

config[:UserDB] = htpasswd

basic_auth = WEBrick::HTTPAuth::BasicAuth.new config

Basic authentication for proxy servers. See BasicAuth for details.

RFC 2617 Digest Access Authentication for WEBrick

Use this class to add digest authentication to a WEBrick servlet.

Here is an example of how to set up DigestAuth:

config = { :Realm => 'DigestAuth example realm' }

htdigest = WEBrick::HTTPAuth::Htdigest.new 'my_password_file'
htdigest.set_passwd config[:Realm], 'username', 'password'
htdigest.flush

config[:UserDB] = htdigest

digest_auth = WEBrick::HTTPAuth::DigestAuth.new config

When using this as with a servlet be sure not to create a new DigestAuth object in the servlet’s initialize. By default WEBrick creates a new servlet instance for every request and the DigestAuth object must be used across requests.

Digest authentication for proxy servers. See DigestAuth for details.

Htpasswd accesses apache-compatible password files. Passwords are matched to a realm where they are valid. For security, the path for a password database should be stored outside of the paths available to the HTTP server.

Htpasswd is intended for use with WEBrick::HTTPAuth::BasicAuth.

To create an Htpasswd database with a single user:

htpasswd = WEBrick::HTTPAuth::Htpasswd.new 'my_password_file'
htpasswd.set_passwd 'my realm', 'username', 'password'
htpasswd.flush

Root of the HTTP status class hierarchy

Stores multipart form data. FormData objects are created when WEBrick::HTTPUtils.parse_form_data is called.

An object representation of a stack frame, initialized by Kernel#caller_locations.

For example:

# caller_locations.rb
def a(skip)
  caller_locations(skip)
end
def b(skip)
  a(skip)
end
def c(skip)
  b(skip)
end

c(0..2).map do |call|
  puts call.to_s
end

Running ruby caller_locations.rb will produce:

caller_locations.rb:2:in `a'
caller_locations.rb:5:in `b'
caller_locations.rb:8:in `c'

Here’s another example with a slightly different result:

# foo.rb
class Foo
  attr_accessor :locations
  def initialize(skip)
    @locations = caller_locations(skip)
  end
end

Foo.new(0..2).locations.map do |call|
  puts call.to_s
end

Now run ruby foo.rb and you should see:

init.rb:4:in `initialize'
init.rb:8:in `new'
init.rb:8:in `<main>'

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

JSON.generator = JSON::Ext::Generator

with the method generator= in JSON.
