Bug#694057: ed: add a mode to deal with crlf-terminated lines

[Matthew Vernon]

Package: ed
Version: 1.6-2
Severity: wishlist
Tags: upstream

Hi,

ed doesn't deal very nicely with text files generated on inferior
operating systems, e.g. those that have lines that end crlf. The
failure mode is that queries / replacement regexps involving $ don't
do what you want.

It would be nice if ed could have a -crlf mode or similar (or even
arbitrary line-ending mode). Any chance? :)

Thanks,

Matthew

Hi,

there's a somewhat old (from 2012) wishlist bug in the Debian BTS
[694057], asking for a proper support of crlf-terminated lines (or
arbitrary line-endings) in ed. Are there any plans to support the
requested mode?

I'm not pretending to implement it, just want to let upstream know about
the requested functionality.

I knew about the issue, but I have not yet done anything about it
because it seems neither easy nor well defined, and implementing it
properly is likely to cause some headaches, for example when stripping
escaped newlines. IMHO using two characters to end a line is a bad idea.

I'll make an attempt at a --crlf option as soon as I find the time.

Best regards,
Antonio.

Thank you for your answer, Antonio.
