Are you sure _every_ line ends in "^M"?
Positive. Every single line shows an ^M at the end. "set fileformat"
gives "unix" after loading. Setting fileformat to "dos" doesn't change
the files interpretation in vim. Somehow I think I miss something.
Uhhh, don't think it *should* automagically delete the ^Ms. I'm always
running into that, and in addition to an almost reflexive alt-EIFD to go
dos-mode, I *still* always have to ':s/^V^M' to get rid of 'em, and I'm
using version 6.4, not even 7.x, so it's definitely been around for a
while.
Setting ff=dos after the file is loaded changes nothing to the contents of the
file data in memory, it only changes how the ends-of-lines will be represented
on output. So if you have a file with mixed ends-of-lines and 'fileformat'
detected as "unix", using ":setlocal ff=dos" will result in some lines having
CR+LF (where there was only LF before) and others (which already had CR+LF
shown as ^M at end of line) will get CR+CR+LF. So this is not the way to go.
To detect a file with mixed ends-of-lines as dos-format, we must first disable
automatic "unix" filetype detection. One way to do this is to set the
'fileformats' (plural) option to the empty string:
:set fileformats=
Now we can manually detect the file's format (see ":help ++opt"):
:e ++ff=dos filename
which will interpret CR+LF as an end-of-line, and LF-without-CR also as an
end-of-line. So now all lines (in memory) are as they should be, with no
spurious end-of-line ^M showing. ^M will only appear if there is a CR not
immediately followed by a LF (either a lone CR in the middle, or more than one
CR before a LF).
We must now save this "file-in-memory" to disk, to make the "repairs"
permanent. Here we have the choice of how we want to save it:
- To save the file with CR+LF at the end of every line, leave 'fileformat' at
its current value ("dos") and just write the file:
:w
- To save the file with LF-only:
:setlocal ff=unix
:w
- To save the file with CR-only:
:setlocal ff=mac
:w
After that, we may want to re-enable automatic fileformat detection: either
set it back to its default:
:set fileformats&
or set the value explicitly, for example:
:set ffs=dos,unix,mac
Best regards,
Tony.
