parse_printf_format(format, opts)

Returns an array of the given format and opts to be used by Kernel#sprintf, if there was a successful Regexp match in the given format from printf

%
<flag>  [#0- +]
<minimum field width> (\*|\*[1-9][0-9]*\$|[1-9][0-9]*)
<precision>.(\*|\*[1-9][0-9]*\$|[1-9][0-9]*|)?
#<length modifier>(hh|h|l|ll|L|q|j|z|t)

pp(*objs)

Prints the given objs calling Object#inspect on each.

See puts for more detail.

Source: show 

# File lib/irb/output-method.rb, line 69
def pp(*objs)
  puts(*objs.collect{|obj| obj.inspect})
end
ppx(prefix, *objs)

Prints the given objs calling Object#inspect on each and appending the given prefix.

See puts for more detail.

Source: show 

# File lib/irb/output-method.rb, line 77
def ppx(prefix, *objs)
  puts(*objs.collect{|obj| prefix+obj.inspect})
end
print(*opts)

Open this method to implement your own output method, raises a NotImplementedError if you don't define print in your own class.

Source: show 

# File lib/irb/output-method.rb, line 25
def print(*opts)
  OutputMethod.Raise NotImplementedError, "print"
end
printf(format, *opts)

Extends IO#printf to format the given opts for Kernel#sprintf using parse_printf_format

Source: show 

# File lib/irb/output-method.rb, line 36
def printf(format, *opts)
  if /(%*)%I/ =~ format
    format, opts = parse_printf_format(format, opts)
  end
  print sprintf(format, *opts)
end
printn(*opts)

Prints the given opts, with a newline delimiter.

Source: show 

# File lib/irb/output-method.rb, line 30
def printn(*opts)
  print opts.join(" "), "\n"
end
puts(*objs)

Calls print on each element in the given objs, followed by a newline character.

Source: show 

# File lib/irb/output-method.rb, line 59
def puts(*objs)
  for obj in objs
    print(*obj)
    print "\n"
  end
