Method: PlainText.tail_inverse

Defined in:
lib/plain_text.rb

.tail_inverse(instr, *rest, **k) ⇒ Object

Module function of #tail_inverse

The return String includes PlainText as Singleton.

Parameters:

  • instr (String) —

    String that is examined.

  • num_in (Integer, Regexp) —

    Number (positive or negative, but not 0) of :unit to extract (Def: 10), or Regexp, which is valid only if unit is :line. If positive, the last num_in lines are returned. If negative, the lines from the num-in-th line from the head are returned. In short, calling this method as tail(3) and tail(-3) is similar to the UNIX commands “tail -n 3” and “tail -n +3”, respectively.

  • unit (Symbol) —

    One of :line (as in -n option), :char, :byte (-c option)

  • inclusive (Boolean) —

    read only when unit is :line. If inclusive (Default), the (entire) line that matches is included in the result.

  • linebreak (String) —

    \n etc (Default: $/), used when unit==:line (Default)

Returns:

  • as instr
