Not with the existing Tramp packages. One ould introduce a new method "sshfs", which works similar as in tramp-gvfs.el: mount the sshfs "filesystem" on a temporary mount point, and map silently file names like "/sshfs:host:/path/to/file" to "/mount_point/path/to/file". Processes on the remote host could be handled similar to the handling for the "ssh" method. I will add an entry to Tramp's todo list.

To make it even more simple, what if we have a list like '(('/volumes/arch' . 'arch')...) of (paths . name_in_ssh_config) What I would want then is that every time I execute a command it's executed instead of my local machine on the remote machine. With some hooks or advising the shell-command could not that work or is too ugly/not working? ^ permalink raw reply [flat|nested] 5+ messages in thread

There are some packages like this. tramp-smb.el, tramp-gvfs.el, tramp-imap.el. All of them add new methods to Tramp. You could try to study them. >> And also I only found a CVS repository, something distributed would be >> better if I want to play with my version. >> Is there anything or should I use git-import magic? Until now, being the only continously working Tramp maintainer, I was too lazy to move somewhere else but cvs. It is on the "maybe we shall change it" list. If needed, we could use a different dvcs, like git or bzr. It depends on what gnu.org supports. > To make it even more simple, what if we have a list like > '(('/volumes/arch' .

Tramp offers own implementations for so called "magic file name handlers". The idea is, that in `file-name-handler-alist' for every such a primitive function it is checked, whether there is a file name handler, depending on the syntax of the file name in question. You find there an entry like ("\\`/\\([^[/:]+\\|[^/]+]\\):" . tramp-file-name-handler) That means, for file names with Tramp's remote file name syntax, the Tramp implementation for these magic functions is applied. See (info "(elisp) Magic File Names") for the list of magic functions. > With some hooks or advising the shell-command could not that work or is > too ugly/not working? One could add another entry to `file-name-handler-alist', like (cons (reqexp-quote "/volumes/arch") 'sshfs-file-name-handler) `sshfs-file-name-handler' would add implementations at least for `file-remote-p', `process-file', `shell-command', `start-file-process'. Maybe also for other functions, don't know. This could be part of Tramp, or a package on its own. Best regards, Michael. ^ permalink raw reply [flat|nested] 5+ messages in thread
