Escapes a string so that it can be safely used in a Bourne shell command line. str can be a non-string object that responds to to_s.

str must not contain NUL characters because of nature of exec system call.

Note that a resulted string should be used unquoted and is not intended for use in double quotes nor in single quotes.

argv = Shellwords.escape("It's better to give than to receive")
argv #=> "It\\'s\\ better\\ to\\ give\\ than\\ to\\ receive"

String#shellescape is a shorthand for this function.

argv = "It's better to give than to receive".shellescape
argv #=> "It\\'s\\ better\\ to\\ give\\ than\\ to\\ receive"

# Search files in lib for method definitions
pattern = "^[ \t]*def "
open("| grep -Ern -e #{pattern.shellescape} lib") { |grep|
  grep.each_line { |line|
    file, lineno, matched_line = line.split(':', 3)
    # ...
  }
}

It is the caller’s responsibility to encode the string in the right encoding for the shell environment where this string is used.

Multibyte characters are treated as multibyte characters, not as bytes.

Returns an empty quoted String if str has a length of zero.

Serializes obj and all descendant objects. If anIO is specified, the serialized data will be written to it, otherwise the data will be returned as a String. If limit is specified, the traversal of subobjects will be limited to that depth. If limit is negative, no checking of depth will be performed.

class Klass
  def initialize(str)
    @str = str
  end
  def say_hello
    @str
  end
end

(produces no output)

o = Klass.new("hello\n")
data = Marshal.dump(o)
obj = Marshal.load(data)
obj.say_hello  #=> "hello\n"

Marshal can’t dump following objects:

• anonymous Class/Module.

• objects which are related to system (ex: Dir, File::Stat, IO, File, Socket and so on)

• an instance of MatchData, Data, Method, UnboundMethod, Proc, Thread, ThreadGroup, Continuation

• objects which define singleton methods

Waits up to the continue timeout for a response from the server provided we’re speaking HTTP 1.1 and are expecting a 100-continue response.

The version of Ruby required by this gem. The ruby version can be specified to the patch-level:

$ ruby -v -e 'p Gem.ruby_version'
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin12.4.0]
#<Gem::Version "2.0.0.247">

Prereleases can also be specified.

Usage:

# This gem will work with 1.8.6 or greater...
spec.required_ruby_version = '>= 1.8.6'

# Only with final releases of major version 2 where minor version is at least 3
spec.required_ruby_version = '~> 2.3'

# Only prereleases or final releases after 2.6.0.preview2
spec.required_ruby_version = '> 2.6.0.preview2'

# This gem will work with 2.3.0 or greater, including major version 3, but lesser than 4.0.0
spec.required_ruby_version = '>= 2.3', '< 4'

Returns URL-unescaped string following RFC 3986.

Sets the SSL/TLS protocol version for the context. This forces connections to use only the specified protocol version. This is deprecated and only provided for backwards compatibility. Use min_version= and max_version= instead.

History

As the name hints, this used to call the SSL_CTX_set_ssl_version() function which sets the SSL method used for connections created from the context. As of Ruby/OpenSSL 2.1, this accessor method is implemented to call min_version= and max_version= instead.

Sets the lower bound on the supported SSL/TLS protocol version. The version may be specified by an integer constant named OpenSSL::SSL::*_VERSION, a Symbol, or nil which means “any version”.

Example

ctx = OpenSSL::SSL::SSLContext.new
ctx.min_version = OpenSSL::SSL::TLS1_1_VERSION
ctx.max_version = OpenSSL::SSL::TLS1_2_VERSION

sock = OpenSSL::SSL::SSLSocket.new(tcp_sock, ctx)
sock.connect # Initiates a connection using either TLS 1.1 or TLS 1.2

Sets the upper bound of the supported SSL/TLS protocol version. See min_version= for the possible values.

Adds session to the session cache.

Removes sessions in the internal cache that have expired at time.
