It'd be nice to be able to treat this like a 'ff'.
ff=unix =<NL>
ff=dos =<CR><NL>
ff=mac =<CR>
ff={anything-else} = custom line terminator
Since that currently doesn't exist, though, is there a plugin to do
roughly what that would accomplish?
I don't know of a plugin, but shooting from the hip, I'd be tempted to
use "tr" as a filter like xxd[1] is used for binary files:
tr '#\012' '\012#'
will swap newlines and "#" signs, which can then be reversed upon
writing to get the originals back.
Good call. I'll likely set up something similar to the 'hex mode'[1]
tip, replacing `%!xxd` and `%!xxd -r` with perl equivs of your `tr`
example. (I want to be able to handle multi-character newlines, and I
know Perl better than sed/awk.)
I'll wikify it if I get it working nicely.
