Return the full path to the cached gem file matching the given name and version requirement. Returns ‘nil’ if no match.
Example:
get_path 'rake', '> 0.4' # "/usr/lib/ruby/gems/1.8/cache/rake-0.4.2.gem" get_path 'rake', '< 0.1' # nil get_path 'rak' # nil (exact name required)
Corresponds to $(LIBPATH) in mkmf
Path of activations from the current list.
Does this dependency request match spec?
NOTE: matches_spec? matches prerelease versions. See also match?
Returns the path to the trusted certificate
Enumerates trusted certificates.
Returns the path to the trusted certificate with the given ASN.1 name
Loads the given certificate_file
Returns the full file path of this frame.
Same as path, except that it will return absolute path even if the frame is in the main script.
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.
["foo", "bar"].lazy.flat_map {|i| i.each_char.lazy}.force #=> ["f", "o", "o", "b", "a", "r"]

[{a:1}, {b:2}].lazy.flat_map {|i| i}.force
#=> [{:a=>1}, {:b=>2}]
Like Enumerable#take_while, but chains operation to be lazy-evaluated.
Sets the length of the authentication tag to be generated or to be given for AEAD ciphers that requires it as in input parameter. Note that not all AEAD ciphers support this method.
In OCB mode, the length must be supplied both when encrypting and when decrypting, and must be before specifying an IV.
Loads the given private key identified by id and data.
An EngineError is raised of the OpenSSL::PKey is unavailable.
