This is probably specific to w32 and CVS Emacs (I use CVS Emacs from
today on w32).
I am using `copy-file' to upload single files to a web site on a unix
host. I did not notice any problems as long as I just uploaded
html-files, but when I uploaded a perl script I got into troubles. I
took me quite some time to find out that `copy-file' somehow added
^M^M to end of line for all lines.
After some testing I found that this happens when the line ending
style is DOS, but not if it is UNIX. So it seems like a ^M is added
instead of removed in that case.
This site is reached through ftp. I use the ftp program from
ftp://ftp.gnu.org/old-gnu/emacs/windows/contrib/ftp-for-win32.zip that
is recommended at http://www.emacswiki.org/cgi-bin/wiki/AngeFtp#toc7.
And `ange-ftp-ftp-program-args' has the standard value.
I do not know if this is a bug in the ftp-program, Emacs or my setup.
I would be glad for some hints here! (I am cross-posting to be able to
collect more info.)
I have to admit I have done something stupid again. Ange-ftp is in no
way to blame here. Nothing in Emacs is to blame here.
This is what happened:
- I uploaded the file using `copy-file' it was uploaded with ftp as binary.
- When I downloaded the file again using another ftp program that was
aware of that the host was a unix host and I was using w32. This program
added ^M before ^J. So the line ending became ^M^M^J (ie CR-CR-LF).
How I found out? Downloaded the file using http instead. Http does not
try to convert line endings as far as I know.
I see no good way of fixing this if I have CR-LF line endings in the
files I want to upload to a unix host. So, finally, I accept the advice
of many here to use LF line endings (ie unix style line endings) for
most of what I do. (And I will implement something to take care of this
in nxhtml-mode.)
Sorry for the noise.
