Register the Symbol
command
as a gem command.
Unregister the Symbol
command
as a gem command.
Return a sorted list of all command names as strings.
Does this dependency match spec
?
NOTE: This is not a convenience method. Unlike match?
this method returns true when spec
is a prerelease version even if this dependency is not a prerelease dependency.
Defaults to use Ruby’s program prefix and suffix.
Indicate if this NameTuple
matches the current platform.
This is ported over from the yaml_tree in 1.9.3
Dump only the raw version string, not the complete object. It’s a string for backwards (RubyGems 1.3.5 and earlier) compatibility.
Load custom marshal format. It’s a string for backwards (RubyGems 1.3.5 and earlier) compatibility.
A recommended version for use with a ~> Requirement.
Sets the rubygems_version
to the current RubyGems version.
Used to hide lines
The search alorithm will group lines into blocks then if those blocks are determined to represent valid code they will be hidden
Returns the RFC822 e-mail text equivalent of the URL, as a String
.
Example:
require 'uri' uri = URI.parse("mailto:ruby-list@ruby-lang.org?Subject=subscribe&cc=myaddr") uri.to_mailtext # => "To: ruby-list@ruby-lang.org\nSubject: subscribe\nCc: myaddr\n\n\n"
Returns Regexp
that is default self.regexp[:ABS_URI_REF]
, unless schemes
is provided. Then it is a Regexp.union
with self.pattern[:X_ABS_URI]
.

OpenSSL::PKCS5.pbkdf2_hmac
has been renamed to OpenSSL::KDF.pbkdf2_hmac
. This method is provided for backwards compatibility.
PKCS #5 PBKDF2 (Password-Based Key Derivation Function 2) in combination with HMAC
. Takes pass, salt and iterations, and then derives a key of length bytes.
For more information about PBKDF2, see RFC 2898 Section 5.2 (tools.ietf.org/html/rfc2898#section-5.2).
The password.
The salt. Salts prevent attacks based on dictionaries of common passwords and attacks based on rainbow tables. It is a public value that can be safely stored along with the password (e.g. if the derived value is used for password storage).
The iteration count. This provides the ability to tune the algorithm. It is better to use the highest count possible for the maximum resistance to brute-force attacks.
The desired length of the derived key in octets.
The hash algorithm used with HMAC
for the PRF. May be a String
representing the algorithm name, or an instance of OpenSSL::Digest
.
Generates a mask bit for a priority level. See mask=
Generate an Image Button Input element as a string.
src
is the URL of the image to use for the button. name
is the input name. alt
is the alternative text for the image.
Alternatively, the attributes can be specified as a hash.
image_button("url") # <INPUT TYPE="image" SRC="url"> image_button("url", "name", "string") # <INPUT TYPE="image" SRC="url" NAME="name" ALT="string"> image_button("SRC" => "url", "ALT" => "string") # <INPUT TYPE="image" SRC="url" ALT="string">
