# Allows the opening of various resources including URIs.
  #
  # If the first argument responds to the 'open' method, 'open' is called on
  # it with the rest of the arguments.
  #
  # If the first argument is a string that begins with xxx://, it is parsed by
  # URI.parse.  If the parsed object responds to the 'open' method,
  # 'open' is called on it with the rest of the arguments.
  #
  # Otherwise, the original Kernel#open is called.
  #
  # Since open-uri.rb provides URI::HTTP#open, URI::HTTPS#open and
  # URI::FTP#open, Kernel[#.]open can accept URIs and strings that begin with
  # http://, https:// and ftp://.  In these cases, the opened file object is
  # extended by OpenURI::Meta.

# OpenURI is an easy-to-use wrapper for net/http, net/https and net/ftp.
#
#== Example
#
# It is possible to open an http, https or ftp URL as though it were a file:
#
#   open("http://www.ruby-lang.org/") {|f|
#     f.each_line {|line| p line}
#   }
#
# The opened file has several getter methods for its meta-information, as
# follows, since it is extended by OpenURI::Meta.
#
#   open("http://www.ruby-lang.org/en") {|f|
#     f.each_line {|line| p line}
#     p f.base_uri         # <URI::HTTP:0x40e6ef2 URL:http://www.ruby-lang.org/en/>
#     p f.content_type     # "text/html"
#     p f.charset          # "iso-8859-1"
#     p f.content_encoding # []
#     p f.last_modified    # Thu Dec 05 02:45:02 UTC 2002
#   }
#
# Additional header fields can be specified by an optional hash argument.
#
#   open("http://www.ruby-lang.org/en/",
#     "User-Agent" => "Ruby/#{RUBY_VERSION}",
#     "From" => "foo@bar.invalid",
#     "Referer" => "http://www.ruby-lang.org/") {|f|
#     # ...
#   }
#
# The environment variables such as http_proxy, https_proxy and ftp_proxy
# are in effect by default.  :proxy => nil disables proxy.
#
#   open("http://www.ruby-lang.org/en/", :proxy => nil) {|f|
#     # ...
#   }
#
# URI objects can be opened in a similar way.
#
#   uri = URI.parse("http://www.ruby-lang.org/en/")
#   uri.open {|f|
#     # ...
#   }
#
# URI objects can be read directly. The returned string is also extended by
# OpenURI::Meta.

# Mixin for HTTP and FTP URIs.
  module OpenRead
    # OpenURI::OpenRead#open provides `open' for URI::HTTP and URI::FTP.
    #
    # OpenURI::OpenRead#open takes optional 3 arguments as:
    #
    #   OpenURI::OpenRead#open([mode [, perm]] [, options]) [{|io| ... }]
    #
    # OpenURI::OpenRead#open returns an IO-like object if block is not given.
    # Otherwise it yields the IO object and return the value of the block.
    # The IO object is extended with OpenURI::Meta.
    #
    # +mode+ and +perm+ are the same as Kernel#open.
    #
    # However, +mode+ must be read mode because OpenURI::OpenRead#open doesn't
    # support write mode (yet).
    # Also +perm+ is ignored because it is meaningful only for file creation.
    #
    # +options+ must be a hash.
    #
    # Each option with a string key specifies an extra header field for HTTP.
    # I.e., it is ignored for FTP without HTTP proxy.
    #
    # The hash may include other options, where keys are symbols:
    #
    # [:proxy]
    #  Synopsis:
    #    :proxy => "http://proxy.foo.com:8000/"
    #    :proxy => URI.parse("http://proxy.foo.com:8000/")
    #    :proxy => true
    #    :proxy => false
    #    :proxy => nil
    #
    #  If :proxy option is specified, the value should be String, URI,
    #  boolean or nil.
    #
    #  When String or URI is given, it is treated as proxy URI.
    #
    #  When true is given or the option itself is not specified,
    #  environment variable `scheme_proxy' is examined.
    #  `scheme' is replaced by `http', `https' or `ftp'.
    #
    #  When false or nil is given, the environment variables are ignored and
    #  connection will be made to a server directly.
    #
    # [:proxy_http_basic_authentication]
    #  Synopsis:
    #    :proxy_http_basic_authentication =>
    #      ["http://proxy.foo.com:8000/", "proxy-user", "proxy-password"]
    #    :proxy_http_basic_authentication =>
    #      [URI.parse("http://proxy.foo.com:8000/"),
    #       "proxy-user", "proxy-password"]
    #
    #  If :proxy option is specified, the value should be an Array with 3
    #  elements.  It should contain a proxy URI, a proxy user name and a proxy
    #  password.  The proxy URI should be a String, an URI or nil.  The proxy
    #  user name and password should be a String.
    #
    #  If nil is given for the proxy URI, this option is just ignored.
    #
    #  If :proxy and :proxy_http_basic_authentication is specified,
    #  ArgumentError is raised.
    #
    # [:http_basic_authentication]
    #  Synopsis:
    #    :http_basic_authentication=>[user, password]
    #
    #  If :http_basic_authentication is specified,
    #  the value should be an array which contains 2 strings:
    #  username and password.
    #  It is used for HTTP Basic authentication defined by RFC 2617.
    #
    # [:content_length_proc]
    #  Synopsis:
    #    :content_length_proc => lambda {|content_length| ... }
    #
    #  If :content_length_proc option is specified, the option value procedure
    #  is called before actual transfer is started.
    #  It takes one argument, which is expected content length in bytes.
    #
    #  If two or more transfer is done by HTTP redirection, the procedure
    #  is called only one for a last transfer.
    #
    #  When expected content length is unknown, the procedure is called with
    #  nil.  This happens when the HTTP response has no Content-Length header.
    #
    # [:progress_proc]
    #  Synopsis:
    #    :progress_proc => lambda {|size| ...}
    #
    #  If :progress_proc option is specified, the proc is called with one
    #  argument each time when `open' gets content fragment from network.
    #  The argument +size+ is the accumulated transferred size in bytes.
    #
    #  If two or more transfer is done by HTTP redirection, the procedure
    #  is called only one for a last transfer.
    #
    #  :progress_proc and :content_length_proc are intended to be used for
    #  progress bar.
    #  For example, it can be implemented as follows using Ruby/ProgressBar.
    #
    #    pbar = nil
    #    open("http://...",
    #      :content_length_proc => lambda {|t|
    #        if t && 0 < t
    #          pbar = ProgressBar.new("...", t)
    #          pbar.file_transfer_mode
    #        end
    #      },
    #      :progress_proc => lambda {|s|
    #        pbar.set s if pbar
    #      }) {|f| ... }
    #
    # [:read_timeout]
    #  Synopsis:
    #    :read_timeout=>nil     (no timeout)
    #    :read_timeout=>10      (10 second)
    #
    #  :read_timeout option specifies a timeout of read for http connections.
    #
    # [:ssl_ca_cert]
    #  Synopsis:
    #    :ssl_ca_cert=>filename
    #
    #  :ssl_ca_cert is used to specify CA certificate for SSL.
    #  If it is given, default certificates are not used.
    #
    # [:ssl_verify_mode]
    #  Synopsis:
    #    :ssl_verify_mode=>mode
    #
    #  :ssl_verify_mode is used to specify openssl verify mode.
    #
    # [:ftp_active_mode]
    #  Synopsis:
    #    :ftp_active_mode=>bool
    #
    #  <tt>:ftp_active_mode => true</tt> is used to make ftp active mode.
    #  Ruby 1.9 uses passive mode by default.
    #  Note that the active mode is default in Ruby 1.8 or prior.
    #
    # [:redirect]
    #  Synopsis:
    #    :redirect=>bool
    #
    #  +:redirect+ is true by default.  <tt>:redirect => false</tt> is used to
    #  disable all HTTP redirects.
    #
    #  OpenURI::HTTPRedirect exception raised on redirection.
    #  Using +true+ also means that redirections between http and ftp are
    #  permitted.
    #
