Problem with UNIX/DOS issue on Emacs for Windows

Problem with UNIX/DOS issue on Emacs for Windows

[exits funnel]

Hello,

I'm running the native Emacs for windows version
21.3.1 on a Win2000 machine.  I'm using it to edit two
different java source files.  One of the source files
looks fine in the buffer but the other, while
formatted correctly, displays '^M' olong with each
carriage return.  I also note that for this file
'(Unix)' appears all the way to the left of the
modeline.

It seems that Emacs thinks that this file is formatted
for unix.  When I look at the files in a hex-editor
they look the same to me - each line ending is marked
by a '0d0a' pair.  I also tried running 'unix2dos'
(under cygwin) on the offending file but to no avail. 
So, what's going on?  On what does emacs base the
determination that the one file is a unix file while
hte other is not?  How can I fix it?  Thanks in
advance for any replies!

This in decimal 13 and 10 meaning C-m and C-j, i.e. they're CR-LF -- 
and this should be DOS.

You could try to revert the buffer from the file with a new encoding: 
C-x RET r <something ending with -dos> RET 
(revert-buffer-with-coding-system).

The line ends are inconsistent. Or there is a ^M in the middle
of a line somewhere. If this is deliberate (part of a string maybe),
you should probably use "\x0d" instead.

There may be better ways, but usually I use the following method to
repair such files (do not type any spaces, they are just seperating
keystrokes for clarity):

Keystrokes             Explanation

M-<                    Ensure you are starting at the beginning of the file.
M-%  C-q C-m RET RET   Replace all ^M characters with nothing.
C-x RET f  d o s RET   Set the file to DOS mode.
C-x C-s                Save the repaired file.

You can omit the third step if you don't mind the file having Unix line
ends.

  ;; doesn't OP need a ! (bang) after the second RET?

Yes, thanks for pointing out the omission.

Google for eol-conversion.el. It is an emacs package the provides you
with a few user functions for changing files between DOS Unix, and MAC.
It also adds these functions under your Edit button on the menu bar.

Thanks Jason.  I never was able to figure out why
Emacs thought the file was a UNIX file, but in any
case the steps you provided got the file straightened
out.  Thanks agains.
