Hm?  This sounds as if you need to implement in Kermit lots of things
that Tramp already does reasonably well.  I'm not sure that this is
the right solution.

Tramp executes a lot of different shell commands during normal
activity.  Even if you don't use filename completion.

So the only thing I really need is:

(1) How do I get a shell prompt from Kermit?
    This goes into a special connection function.  Look at
    tramp-open-connection-rsh and tramp-open-connection-telnet for
    some examples.
    Probably it is enough to start Kermit, then send "telnet

I think it shouldn't do that, as the host is running Unix, not Cygwin,
right?  So why does tramp-handle-expand-file-name change file into
c:/cygwin/home/user/file?

Ah.  tramp-handle-expand-file-name runs the real expand-file-name
operation.  I guess that this does the wrong thing.  Is this correct?

Maybe tramp-handle-expand-file-name should do all the hard work
itself, rather than relying on the regular function.  In fact, it
seems that by reusing existing filename operations, I get into
trouble.  So I think that in the long run I will need to just
reimplement all the functions myself.  It's a pity, though.

Maybe not, but kermit also already does these thing very well.
Folks have been scripting terminal sessions with kermit for
years, so it has lots of features to simplify the job.

That's pretty much the way it works, there are just other commands
for opening other kinds of connections (rlogin, ssh, etc).

tramp ($Id: tramp.el,v 1.8 2002/04/15 11:27:18 kaig Exp $); tramp-methods defcustom mismatch


--bug report follows this line--

I noticed that when trying to customize tramp-methods, there appeared
to be a mistmatch between the variable and the type.  After bit of
playing, I found that tramp-su-program element was the culprit, but I
can't figure out why.

My other problem is under Cygwin, while I can get dired to work if I
choose the scpx method, trying to load a file hangs.  I'm wondering if
the tramp isn't detecting that the scp operation has completed.  

Thanks.

This sounds as if it might be useful to write another package which
does it this way.  I think most of the Tramp code isn't useful in that
case.

For reusing a lot of Tramp code, the other mechanism seems right,
where Kermit opens a shell prompt at the remote end and then calls
Kermit on the remote side as appropriate.

Are you willing to work on this?

Tramp: import existing SourceForge CVS tree

Tramp now lives on SourceForge and I would like to migrate it to
Savannah.  Can you import the CVS repository from SourceForge?

I think it makes more sense for you to just use the most current
repository version from SourceForge, rather than setting up an
appointment with me.  Just tell me from when was the tarball.

The SourceForge tarball is available under the following URL:

http://cvs.sourceforge.net/cvstarballs/tramp-cvsroot.tar.gz

Thanks,
kai

I have now also committed it to CVS.  So you can also use the most
recent version from there.

Note that the tarball available from SourceForge contains the CVSROOT
directory; is this a problem?

Hm.  There is code in Tramp to detect this:

    (when (>= numchase numchase-limit)
      (error "Maximum number (%d) of symlinks exceeded" numchase-limit))

Do you have these lines in tramp-handle-file-truename?  Maybe
numchase-limit is too high (it's 100)?
