parse_printf_format(format, opts) click to toggle source

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)
<conversion specifier>[diouxXeEfgGcsb%]

 
               # File irb/output-method.rb, line 53
def parse_printf_format(format, opts)
  return format, opts if $1.size % 2 == 1
end

pp(*objs) click to toggle source

Prints the given objs calling Object#inspect on each.

See puts for more detail.

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

ppx(prefix, *objs) click to toggle source

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

See puts for more detail.

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

print(*opts) click to toggle source

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

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

printf(format, *opts) click to toggle source

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

 
               # File 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) click to toggle source

Prints the given opts, with a newline delimiter.

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

puts(*objs) click to toggle source

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

 
               # File irb/output-method.rb, line 59
def puts(*objs)
