Overview
An abstract output class for IO in irb. This is mainly used internally by Notifier. You can define your own output method to use with Irb.new, or Context.new
Instance Method Summary
-
#parse_printf_format(format, opts)
Returns an array of the given
format
andopts
to be used byKernel.sprintf
, if there was a successful Regexp match in the givenformat
from #printf -
#pp(*objs)
Prints the given
objs
callingObject#inspect
on each. -
#ppx(prefix, *objs)
Prints the given
objs
callingObject#inspect
on each and appending the givenprefix
. -
#print(*opts)
Open this method to implement your own output method, raises a NotImplementedError if you don't define #print in your own class.
-
#printf(format, *opts)
Extends
IO#printf
to format the givenopts
forKernel.sprintf
using #parse_printf_format -
#printn(*opts)
Prints the given
opts
, with a newline delimiter. -
#puts(*objs)
Calls #print on each element in the given
objs
, followed by a newline character.
