This is a null install as this specification is already installed. options are ignored.
This is a null install as a locked specification is considered installed. options are ignored.
The platform this gem works on.
Installs this specification using the Gem::Installer options. The install method yields a Gem::Installer instance, which indicates the gem will be installed, or nil, which indicates the gem is already installed.
After installation spec is updated to point to the just-installed specification.
This is a null install as this gem was unpacked into a directory. options are ignored.
Returns the file name of this frame. This will generally be an absolute path, unless the frame is in the main script, in which case it will be the script location passed on the command line.
For example, using caller_locations.rb from Thread::Backtrace::Location
loc = c(0..1).first loc.path #=> caller_locations.rb
This method verifies that there are no (obvious) ambiguities with the provided col_sep and strip parsing options. For example, if col_sep and strip were both equal to \t, then there would be no clear way to parse the input.
Returns a new lazy enumerator with the concatenated results of running block once for every element in the lazy enumerator.
["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:
x responds to both each and force, which means that x is a lazy enumerator.
x 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}]
Returns a new lazy enumerator with the concatenated results of running block once for every element in the lazy enumerator.

Like Enumerable#take_while, but chains operation to be lazy-evaluated.
Like Enumerable#take, but chains operation to be lazy-evaluated.
Generates a random prime number of bit length bits. If safe is set to true, generates a safe prime. If add is specified, generates a prime that fulfills condition p % add = rem.
Sets the authentication tag to verify the integrity of the ciphertext. This can be called only when the cipher supports AE. The tag must be set after calling Cipher#decrypt, Cipher#key= and Cipher#iv=, but before calling Cipher#final. After all decryption is performed, the tag is verified automatically in the call to Cipher#final.
For OCB mode, the tag length must be supplied with auth_tag_len= beforehand.
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 default length of 16 bytes or the length previously set by auth_tag_len= will be used. For maximum security, the longest possible should be chosen.
The tag may only be retrieved after calling Cipher#final.
Called with encoding when the YAML stream starts. This method is called once per stream. A stream may contain multiple documents.
See the constants in Psych::Parser for the possible values of encoding.
Called when the document starts with the declared version, tag_directives, if the document is implicit.
version will be an array of integers indicating the YAML version being dealt with, tag_directives is a list of tuples indicating the prefix and suffix of each tag, and implicit is a boolean indicating whether the document is started implicitly.
Given the following YAML:
%YAML 1.1 %TAG ! tag:tenderlovemaking.com,2009: --- !squee
The parameters for start_document must be this:
version # => [1, 1] tag_directives # => [["!", "tag:tenderlovemaking.com,2009:"]] implicit # => false
Called when a sequence is started.
anchor is the anchor associated with the sequence or nil. tag is the tag associated with the sequence or nil. implicit a boolean indicating whether or not the sequence was implicitly started. style is an integer indicating the list style.
See the constants in Psych::Nodes::Sequence for the possible values of style.
Here is a YAML document that exercises most of the possible ways this method can be called:
--- - !!seq [ a ] - &pewpew - b
The above YAML document consists of three lists, an outer list that contains two inner lists. Here is a matrix of the parameters sent to represent these lists:
# anchor tag implicit style [nil, nil, true, 1 ] [nil, "tag:yaml.org,2002:seq", false, 2 ] ["pewpew", nil, true, 1 ]
Called when a map starts.
anchor is the anchor associated with the map or nil. tag is the tag associated with the map or nil. implicit is a boolean indicating whether or not the map was implicitly started. style is an integer indicating the mapping style.
See the constants in Psych::Nodes::Mapping for the possible values of style.
Here is a YAML document that exercises most of the possible ways this method can be called:
---
k: !!map { hello: world }
v: &pewpew
hello: world
The above YAML document consists of three maps, an outer map that contains two inner maps. Below is a matrix of the parameters sent in order to represent these three maps:
# anchor tag implicit style [nil, nil, true, 1 ] [nil, "tag:yaml.org,2002:map", false, 2 ] ["pewpew", nil, true, 1 ]
Called before each event with line/column information.
