Evaluates erb providing servlet_request and servlet_response as local variables.

Returns, when successfully the only child-node

@param [Vertex] other the other vertex to compare to @return [Boolean] whether the two vertices are equal, determined

solely by {#name} and {#payload} equality

Creates the initial state for the resolution, based upon the {#requested} dependencies @return [DependencyState] the initial state for the resolution

Get all [gem, version] from the command line.

An argument in the form gem:ver is pull apart into the gen name and version, respectively.

Returns an array of two elements: the filename where the calling method is located, and the line number where it is defined.

Takes an optional argument i, which specifies how many callers up the stack to look.

Examples:

require 'rss/utils'

def foo
  p RSS::Utils.get_file_and_line_from_caller
  p RSS::Utils.get_file_and_line_from_caller(1)
end

def bar
  foo
end

def baz
  bar
end

baz
# => ["test.rb", 5]
# => ["test.rb", 9]

If i is not given, or is the default value of 0, it attempts to figure out the correct value. This is useful when in combination with instance_eval. For example:

require 'rss/utils'

def foo
  p RSS::Utils.get_file_and_line_from_caller(1)
end

def bar
  foo
end

instance_eval <<-RUBY, *RSS::Utils.get_file_and_line_from_caller
def baz
  bar
end
RUBY

baz

# => ["test.rb", 8]

Returns a new lazy enumerator with the concatenated results of running block once for every element in lazy.

["foo", "bar"].lazy.flat_map {|i| i.each_char.lazy}.force
#=> ["f", "o", "o", "b", "a", "r"]

A value x returned by block is decomposed if either of the following conditions is true:

a) <i>x</i> responds to both each and force, which means that
   <i>x</i> is a lazy enumerator.
b) <i>x</i> is an array or responds to to_ary.

Otherwise, x is contained as-is in the return value.

[{a:1}, {b:2}].lazy.flat_map {|i| i}.force
#=> [{:a=>1}, {:b=>2}]

Sets the cipher’s additional authenticated data. This field must be set when using AEAD cipher modes such as GCM or CCM. If no associated data shall be used, this method must still be called with a value of “”. The contents of this field should be non-sensitive data which will be added to the ciphertext to generate the authentication tag which validates the contents of the ciphertext.

The AAD must be set prior to encryption or decryption. In encryption mode, it must be set after calling Cipher#encrypt and setting Cipher#key= and Cipher#iv=. When decrypting, the authenticated data must be set after key, iv and especially after the authentication tag has been set. I.e. set it only after calling Cipher#decrypt, Cipher#key=, Cipher#iv= and Cipher#auth_tag= first.

Sets the authentication tag to verify the contents of the ciphertext. The tag must be set after calling Cipher#decrypt, Cipher#key= and Cipher#iv=, but before assigning the associated authenticated data using Cipher#auth_data= and of course, before decrypting any of the ciphertext. After all decryption is performed, the tag is verified automatically in the call to Cipher#final.

Gets the authentication tag generated by Authenticated Encryption Cipher modes (GCM for example). This tag may be stored along with the ciphertext, then set on the decryption cipher to authenticate the contents of the ciphertext against changes. If the optional integer parameter tag_len is given, the returned tag will be tag_len bytes long. If the parameter is omitted, the maximum length of 16 bytes will be returned. For maximum security, the default of 16 bytes should be chosen.

The tag may only be retrieved after calling Cipher#final.

Gets the value of key from the given section

Given the following configurating file being loaded:

config = OpenSSL::Config.load('foo.cnf')
  #=> #<OpenSSL::Config sections=["default"]>
puts config.to_s
  #=> [ default ]
  #   foo=bar

You can get a specific value from the config if you know the section and key like so:

config.get_value('default','foo')
  #=> "bar"

Set the target key with a given value under a specific section.

Given the following configurating file being loaded:

config = OpenSSL::Config.load('foo.cnf')
  #=> #<OpenSSL::Config sections=["default"]>
puts config.to_s
  #=> [ default ]
  #   foo=bar

You can set the value of foo under the default section to a new value:

config.add_value('default', 'foo', 'buzz')
  #=> "buzz"
puts config.to_s
  #=> [ default ]
  #   foo=buzz
