Any errors you see here are probably due to a bug in Ruby’s OpenSSL implementation.

Returns a default parser

Spawns the specified command on a newly allocated pty. You can also use the alias ::getpty.

The command’s controlling tty is set to the slave device of the pty and its standard input/output/error is redirected to the slave device.

command and command_line are the full commands to run, given a String. Any additional arguments will be passed to the command.

Return values

In the non-block form this returns an array of size three, [r, w, pid].

In the block form these same values will be yielded to the block:

r

A readable IO that contains the command’s standard output and standard error

w

A writable IO that is the command’s standard input

pid

The process identifier for the command.

Closes the syslog facility. Raises a runtime exception if it is not open.

Calculates Adler-32 checksum for string, and returns updated value of adler. If string is omitted, it returns the Adler-32 initial value. If adler is omitted, it assumes that the initial value is given to adler. If string is an IO instance, reads from the IO until the IO returns nil and returns Adler-32 of all read data.

Example usage:

require "zlib"

data = "foo"
puts "Adler32 checksum: #{Zlib.adler32(data).to_s(16)}"
#=> Adler32 checksum: 2820145

Returns true if the named file exists and has a zero size.

file_name can be an IO object.

Returns true if the named file is a block device.

file_name can be an IO object.

Returns the currently set formatter. By default, it is set to DidYouMean::Formatter.

Updates the primary formatter used to format the suggestions.

Is uri the URI for the current local server?

Is uri the URI for the current local server?

Set the changed state of this object. Notifications will be sent only if the changed state is true.

state

Boolean indicating the changed state of this Observable.

Returns true if this object’s state has been changed since the last notify_observers call.

Synopsis

URI::regexp([match_schemes])

Args

match_schemes

Array of schemes. If given, resulting regexp matches to URIs whose scheme is one of the match_schemes.

Description

Returns a Regexp object which matches to URI-like strings. The Regexp object returned by this method includes arbitrary number of capture group (parentheses). Never rely on its number.

Usage

require 'uri'

# extract first URI from html_string
html_string.slice(URI.regexp)

# remove ftp URIs
html_string.sub(URI.regexp(['ftp']), '')

# You should not rely on the number of parentheses
html_string.scan(URI.regexp) do |*matches|
  p $&
end

Raises a TypeError to prevent cloning.

By default calls instance(). Override to retain singleton state.

Returns the result of converting the serialized data in source into a Ruby object (possibly with associated subordinate objects). source may be either an instance of IO or an object that responds to to_str. If proc is specified, each object will be passed to the proc, as the object is being deserialized.

Never pass untrusted data (including user supplied input) to this method. Please see the overview for further details.
