class IRB::Notifier::AbstractNotifier

An abstract class, or superclass, for CompositeNotifier and LeveledNotifier to inherit. It provides several wrapper methods for the OutputMethod object used by the Notifier.

Attributes

prefix [R]

The prefix for this Notifier, which is appended to all objects being inspected during output.

new (prefix, base_notifier)

Creates a new Notifier object

# File lib/irb/notifier.rb, line 41
def initialize(prefix, base_notifier)
  @prefix = prefix
  @base_notifier = base_notifier
end

exec_if () { |base_notifier| ... }

Execute the given block if notifications are enabled.

# File lib/irb/notifier.rb, line 99
def exec_if
  yield(@base_notifier) if notify?
end

notify? ()

A wrapper method used to determine whether notifications are enabled.

Defaults to true.

# File lib/irb/notifier.rb, line 53
def notify?
  true
end

pp (*objs)

Same as ppx, except it uses the prefix given during object initialization. See OutputMethod#ppx for more detail.

# File lib/irb/notifier.rb, line 82
def pp(*objs)
  if notify?
    @base_notifier.ppx @prefix, *objs
  end
end

ppx (prefix, *objs)

Same as pp, except it concatenates the given prefix with the prefix given during object initialization.

See OutputMethod#ppx for more detail.

# File lib/irb/notifier.rb, line 92
def ppx(prefix, *objs)
  if notify?
    @base_notifier.ppx @prefix+prefix, *objs
  end
end

print (*opts)

See OutputMethod#print for more detail.

# File lib/irb/notifier.rb, line 58
def print(*opts)
  @base_notifier.print prefix, *opts if notify?
end

printf (format, *opts)

# File lib/irb/notifier.rb, line 68
def printf(format, *opts)
  @base_notifier.printf(prefix + format, *opts) if notify?
end

printn (*opts)

# File lib/irb/notifier.rb, line 63
def printn(*opts)
  @base_notifier.printn prefix, *opts if notify?
end

puts (*objs)

See OutputMethod#puts for more detail.

# File lib/irb/notifier.rb, line 73
def puts(*objs)
  if notify?
    @base_notifier.puts(*objs.collect{|obj| prefix + obj.to_s})
  end
end
