The attached patch seems to work with my extremely limited testing so that Perl scripts can be any of the LF, CRLF, or CR end-of-lined. (Not that great a feat since the LF and CRLF have both worked already.) (No, this patch doesn't do the mythical LFCR.) The new test script t/comp/eol.t is the extremely limited testing, it tries to create a script in all the three EOLings, and parse and execute it, and verify the results. I've only tried this in one UNIX variant of the PerlIO_fast_gets() kind, so I can't really say that I've tested much. Looking at the crux of the matter, Perl_sv_gets(), I notice both that strange and wonderful lands like VMS and non-PerlIO_fast_gets() lands might not be quite right yet. Furthermore, there might be more parsing code changes needed in various places (mostly toke.c, probably) like the changes I needed to make to format parsing. An additional doubt I have whether my changes slowed down, err, quieted down, the screaming of Perl_sv_gets() too much. That is, does my extra logic slow down reading in scripts too much. Of course, the ultimate acid test will be whether this patch really works in Mac OS Classic (CR) and whether the patch didn't broke Win32 (CRLF). -- Jarkko Hietaniemi <jhi@iki.fi> http://www.iki.fi/jhi/ "There is this special biologist word we use for 'stable'.
