NT-emacs & Cygwin ssh/scp

[David Starks-B. <da...@st...>]

Greetings,

I managed to get tramp working with NT-Emacs and Cygwin ssh/scp, based
on the scpx method.  There were two main problems:

1.  Cygwin's scp cannot handle the Windows path of the local tramp
    temp file.  Without any Cygwin-awareness in Emacs, I handle it by
    invoking a wrapper script instead of scp directly.  The script
    converts the Windows path to the Cygwin path before invoking scp.
    If the remote hostname is just one letter, it will fool the
    script. :-)

2.  Cygwin-mount.el is a popular way to make Emacs "Cygwin-aware".
    But it breaks tramp.  The problem is first manifested in
    tramp-find-file-exists-command, where "/" in the remote filesystem
    gets translated to "/cygwin/".  I didn't investigate further, I
    just disabled cygwin-mount.  It would be great if cygwin-mount and
    tramp could co-exist.  (Perhaps cygwin-mount could even be used to
    supply a Cygwin path to scp?)

Other than that, it was just a matter of invoking runemacs from the
Cygwin bash shell, after invoking ssh-agent and ssh-add.  Then scp can
communicate with ssh-agent and no password or passphrase is required.

I wrote everything down at
<http://www.starks-browning.com/david/tramp/>.  If anyone has a better
approach, I'd like to hear about it.  Even better, if anyone has ideas
for using both cygwin-mount and tramp, that would be really nice.

Thanks for tramp!

Kind regards,
David
