Subject: Chopping and chomping to no avail


It seems chop and chomp just won't do what I want.

My input has lines ending with \n or \r\n,
possibly both in the same file, and there is
also the possibility that the last line will
not have either.

chop works for lines ending with \n or \r\n,
but incorrectly removes the last character
from the last line if it's unterminated.

chomp won't remove the last char from an
unterminated line, but it only works on one
type of record separator, so it won't handle
\n and \r\n at the same time.

I can say:

    str.chomp.chomp("\r")

or make up some regexp horror, but I'd really
like to know if there is some method that I've
overlooked that can flexibly, reliably and
safely remove a line terminator from any string.
