# 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:
#
# URI.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.
#
# URI.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.
#
# URI.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. Here we disable proxy:
#
# URI.open("http://www.ruby-lang.org/en/", :proxy => nil) {|f|
# # ...
# }
#
# See OpenURI::OpenRead.open and URI.open for more on available options.
#
# 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.

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 transfers are performed by HTTP redirection, the
# procedure is called only once for the 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.
#
# [:open_timeout]
# Synopsis:
# :open_timeout=>nil (no timeout)
# :open_timeout=>10 (10 second)
#
# :open_timeout option specifies a timeout of open for http connections.
#
# [:ssl_ca_cert]
# Synopsis:
# :ssl_ca_cert=>filename or an Array of filenames
#
# :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.
