NAME

       PerlIO::eol - PerlIO layer for normalizing line endings

VERSION

       This document describes version 0.14 of PerlIO::eol, released December 18, 2006.

SYNOPSIS

           binmode STDIN, ":raw:eol(LF)";
           binmode STDOUT, ":raw:eol(CRLF)";
           open FH, "+<:raw:eol(LF-Native)", "file";

           binmode STDOUT, ":raw:eol(CRLF?)"; # warns on mixed newlines
           binmode STDOUT, ":raw:eol(CRLF!)"; # dies on mixed newlines

           use PerlIO::eol qw( eol_is_mixed );
           my $pos = eol_is_mixed( "mixed\nstring\r" );

DESCRIPTION

       This layer normalizes any of "CR", "LF", "CRLF" and "Native" into the designated line
       ending.  It works for both input and output handles.

       If you specify two different line endings joined by a "-", it will use the first one for
       reading and the second one for writing.  For example, the "LF-CRLF" encoding means that
       all input should be normalized to "LF", and all output should be normalized to "CRLF".

       By default, data with mixed newlines are normalized silently.  Append a "!"  to the line
       ending will raise a fatal exception when mixed newlines are spotted.  Append a "?" will
       raise a warning instead.

       It is advised to pop any potential ":crlf" or encoding layers before this layer; this is
       usually done using a ":raw" prefix.

       This module also optionally exports a "eol_is_mixed" function; it takes a string and
       returns the position of the first inconsistent line ending found in that string, or 0 if
       the line endings are consistent.

       The "CR", "LF", "CRLF" and "NATIVE" constants are also exported at request.
