Results for: "Pathname"

Raises when the given argument word can’t be completed uniquely.

A pattern is an object that wraps a Ruby pattern matching expression. The expression would normally be passed to an ‘in` clause within a `case` expression or a rightward assignment expression. For example, in the following snippet:

case node
in ConstantPathNode[ConstantReadNode[name: :Prism], ConstantReadNode[name: :Pattern]]
end

the pattern is the ConstantPathNode[...] expression.

The pattern gets compiled into an object that responds to call by running the compile method. This method itself will run back through Prism to parse the expression into a tree, then walk the tree to generate the necessary callable objects. For example, if you wanted to compile the expression above into a callable, you would:

callable = Prism::Pattern.new("ConstantPathNode[ConstantReadNode[name: :Prism], ConstantReadNode[name: :Pattern]]").compile
callable.call(node)

The callable object returned by compile is guaranteed to respond to call with a single argument, which is the node to match against. It also is guaranteed to respond to ===, which means it itself can be used in a ‘case` expression, as in:

case node
when callable
end

If the query given to the initializer cannot be compiled into a valid matcher (either because of a syntax error or because it is using syntax we do not yet support) then a Prism::Pattern::CompilationError will be raised.

Generated when trying to lookup a gem to indicate that the gem was found, but that it isn’t usable on the current platform.

Provides classes and methods to request, create and validate RFC3161-compliant timestamps. Request may be used to either create requests from scratch or to parse existing requests that again can be used to request timestamps from a timestamp server, e.g. via the net/http. The resulting timestamp response may be parsed using Response.

Please note that Response is read-only and immutable. To create a Response, an instance of Factory as well as a valid Request are needed.

Create a Response:

#Assumes ts.p12 is a PKCS#12-compatible file with a private key
#and a certificate that has an extended key usage of 'timeStamping'
p12 = OpenSSL::PKCS12.new(File.binread('ts.p12'), 'pwd')
md = OpenSSL::Digest.new('SHA1')
hash = md.digest(data) #some binary data to be timestamped
req = OpenSSL::Timestamp::Request.new
req.algorithm = 'SHA1'
req.message_imprint = hash
req.policy_id = "1.2.3.4.5"
req.nonce = 42
fac = OpenSSL::Timestamp::Factory.new
fac.gen_time = Time.now
fac.serial_number = 1
timestamp = fac.create_timestamp(p12.key, p12.certificate, req)

Verify a timestamp response:

#Assume we have a timestamp token in a file called ts.der
ts = OpenSSL::Timestamp::Response.new(File.binread('ts.der'))
#Assume we have the Request for this token in a file called req.der
req = OpenSSL::Timestamp::Request.new(File.binread('req.der'))
# Assume the associated root CA certificate is contained in a
# DER-encoded file named root.cer
root = OpenSSL::X509::Certificate.new(File.binread('root.cer'))
# get the necessary intermediate certificates, available in
# DER-encoded form in inter1.cer and inter2.cer
inter1 = OpenSSL::X509::Certificate.new(File.binread('inter1.cer'))
inter2 = OpenSSL::X509::Certificate.new(File.binread('inter2.cer'))
ts.verify(req, root, inter1, inter2) -> ts or raises an exception if validation fails

Module that defines helper methods for pretty_print.

An error class raised when dynamic parts are found while computing a constant path’s full name. For example: Foo::Bar::Baz -> does not raise because all parts of the constant path are simple constants var::Bar::Baz -> raises because the first part of the constant path is a local variable

An X.509 name represents a hostname, email address or other entity associated with a public key.

You can create a Name by parsing a distinguished name String or by supplying the distinguished name as an Array.

name = OpenSSL::X509::Name.parse_rfc2253 'DC=example,CN=nobody'

name = OpenSSL::X509::Name.new [['CN', 'nobody'], ['DC', 'example']]

An error class raised when missing nodes are found while computing a constant path’s full name. For example:

Foo

-> raises because the constant path is missing the last part

A source that is represented by a file path.

A field that represents the file path.

A representation of a DNS name.

Generator

Passwd is a placeholder Struct for user database on Unix systems.

The struct contains the following members

name

contains the short login name of the user as a String.

passwd

contains the encrypted password of the user as a String. an 'x' is returned if shadow passwords are in use. An '*' is returned if the user cannot log in using a password.

uid

contains the integer user ID (uid) of the user.

gid

contains the integer group ID (gid) of the user’s primary group.

dir

contains the path to the home directory of the user as a String.

shell

contains the path to the login shell of the user as a String.

The following members below are system-dependent

gecos

contains a longer String description of the user, such as a full name. Some Unix systems provide structured information in the gecos field, but this is system-dependent.

change

password change time(integer).

quota

quota value(integer).

age

password age(integer).

class

user access class(string).

comment

comment(string).

expire

account expiration time(integer).
