Results for: "Pathname"

Returns a hash representing information about named captures of rxp.

A key of the hash is a name of the named captures. A value of the hash is an array which is list of indexes of corresponding named captures.

/(?<foo>.)(?<bar>.)/.named_captures
#=> {"foo"=>[1], "bar"=>[2]}

/(?<foo>.)(?<foo>.)/.named_captures
#=> {"foo"=>[1, 2]}

If there are no named captures, an empty hash is returned.

/(.)(.)/.named_captures
#=> {}

Returns the socket path as a string.

Addrinfo.unix("/tmp/sock").unix_path       #=> "/tmp/sock"

Returns library name. If the method fails to access library name, WIN32OLERuntimeError is raised.

tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library')
tlib.library_name # => Excel

Set date-time format.

datetime_format

A string suitable for passing to strftime.

Returns the date format being used. See datetime_format=

Returns a Hash using named capture.

A key of the hash is a name of the named captures. A value of the hash is a string of last successful capture of corresponding group.

m = /(?<a>.)(?<b>.)/.match("01")
m.named_captures #=> {"a" => "0", "b" => "1"}

m = /(?<a>.)(?<b>.)?/.match("0")
m.named_captures #=> {"a" => "0", "b" => nil}

m = /(?<a>.)(?<a>.)/.match("01")
m.named_captures #=> {"a" => "1"}

m = /(?<a>x)|(?<a>y)/.match("x")
m.named_captures #=> {"a" => "x"}

Ensures that names only includes names for the :rdoc, :clobber_rdoc and :rerdoc. If other names are given an ArgumentError is raised.

Iterates over all hostnames for address.

Iterates over all hostnames for address.

Find the full path to the executable for gem name. If the exec_name is not given, an exception will be raised, otherwise the specified executable’s path is returned. requirements allows you to specify specific gem versions.

Reset the dir and path values. The next time dir or path is requested, the values will be calculated from scratch. This is mainly used by the unit tests to provide test isolation.

Use the home and paths values for Gem.dir and Gem.path. Used mainly by the unit tests to provide environment isolation.

Default gem load path

Prefix and suffix the program filename the same as ruby.

Returns the destination encoding name as a string.

Returns the destination encoding name as a string.

Return the list of all instance variables.

Merges a base path base, with relative path rel, returns a modified base path.

Generates new parameters for the algorithm. algo_name is a String that represents the algorithm. The optional argument options is a Hash that specifies the options specific to the algorithm. The order of the options can be important.

A block can be passed optionally. The meaning of the arguments passed to the block varies depending on the implementation of the algorithm. The block may be called once or multiple times, or may not even be called.

For the supported options, see the documentation for the ‘openssl genpkey’ utility command.

Example

pkey = OpenSSL::PKey.generate_parameters("DSA", "dsa_paramgen_bits" => 2048)
p pkey.p.num_bits #=> 2048

Returns the name of the cipher which may differ slightly from the original name provided.

Returns the sn of this Digest algorithm.

Example

digest = OpenSSL::Digest.new('SHA512')
puts digest.name # => SHA512

Get the descriptive name for this engine.

OpenSSL::Engine.load
OpenSSL::Engine.engines #=> [#<OpenSSL::Engine#>, ...]
OpenSSL::Engine.engines.first.name
  #=> "RSAX engine support"
