Results for: "Logger"

Creates a global method from the given C signature.

The Fiddle::CompositeHandler instance

Will raise an error if no handlers are open.

See IO#getch.

See IO#getpass.

Reads the next “line” from the stream. Lines are separated by eol. If limit is provided the result will not be longer than the given number of bytes.

eol may be a String or Regexp.

Unlike IO#gets the line read will not be assigned to +$_+.

Unlike IO#gets the separator must be provided if a limit is provided.

Reads one character from the stream. Returns nil if called at end of file.

Pushes character c back onto the stream such that a subsequent buffered character read will return it.

Unlike IO#getc multiple bytes may be pushed back onto the stream.

Has no effect on unbuffered reads (such as sysread).

Closes the SSLSocket and flushes any unwritten data.

If a block is given, it prints out each of the elements encountered. Block parameters are (in that order):

• depth: The recursion depth, plus one with each constructed value being encountered (Integer)

• offset: Current byte offset (Integer)

• header length: Combined length in bytes of the Tag and Length headers. (Integer)

• length: The overall remaining length of the entire data (Integer)

• constructed: Whether this value is constructed or not (Boolean)

• tag_class: Current tag class (Symbol)

• tag: The current tag number (Integer)

Example

der = File.binread('asn1data.der')
OpenSSL::ASN1.traverse(der) do | depth, offset, header_len, length, constructed, tag_class, tag|
  puts "Depth: #{depth} Offset: #{offset} Length: #{length}"
  puts "Header length: #{header_len} Tag: #{tag} Tag class: #{tag_class} Constructed: #{constructed}"
end

Generate a BlockQuote element as a string.

cite can either be a string, give the URI for the source of the quoted text, or a hash, giving all attributes of the element, or it can be omitted, in which case the element has no attributes.

The body is provided by the passed-in no-argument block

blockquote("http://www.example.com/quotes/foo.html") { "Foo!" }
  #=> "<BLOCKQUOTE CITE=\"http://www.example.com/quotes/foo.html\">Foo!</BLOCKQUOTE>

Returns an Array of Range objects which represent the Range: HTTP header field, or nil if there is no such header.

Parses self destructively in order and returns self containing the rest arguments left unparsed.

Parses self destructively in permutation mode and returns self containing the rest arguments left unparsed.

Substitution of getopts is possible as follows. Also see OptionParser#getopts.

def getopts(*args)
  ($OPT = ARGV.getopts(*args)).each do |opt, val|
    eval "$OPT_#{opt.gsub(/[^A-Za-z0-9_]/, '_')} = val"
  end
rescue OptionParser::ParseError
end

Is local fetching enabled?

Displays an alert statement. Asks a question if given.

Calls say with msg or the results of the block if really_verbose is true.

SecureRandom.alphanumeric generates a random alphanumeric string.

The argument n specifies the length, in characters, of the alphanumeric string to be generated.

If n is not specified or is nil, 16 is assumed. It may be larger in the future.

The result may contain A-Z, a-z and 0-9.

require 'securerandom'

SecureRandom.alphanumeric     #=> "2BuBuLf3WfSKyQbR"
SecureRandom.alphanumeric(10) #=> "i6K93NdqiH"

If a secure random number generator is not available, NotImplementedError is raised.
