I'm trying to make ido work sensibly with tramp syntax -- but
getting a grip on file-name-all-completions is really a nightmare.
Ido uses file-name-all-completions to get a list of all possible
completions of "the next component" to be entered by the user.
Now, consider these tramp file name:
/method:[EMAIL PROTECTED]:/file
/[EMAIL PROTECTED]:/file
/host:/file
Ideally, ido would like to call file-name-all-completions like this:
(file-name-all-completions "/method:" "")
(file-name-all-completions "/method:user@" "")
(file-name-all-completions "/method:[EMAIL PROTECTED]:" "")
(file-name-all-completions "/method:[EMAIL PROTECTED]:/file" "")
(file-name-all-completions "/user@" "")
(file-name-all-completions "/[EMAIL PROTECTED]:" "")
(file-name-all-completions "/host:" "")
However, this does not always work -- look at these examples:
========
(file-name-all-completions "/telnet:" "")
=> OK
========
(file-name-all-completions "/telnet:kfs@" "")
=> ERROR: "Not a tramp file name: "
The desired result can be obtained with this call
(remove leading / of first arg, add / to second arg):
(file-name-all-completions "telnet:kfs@" "/")
=> OK
========
(file-name-all-completions "/telnet:[EMAIL PROTECTED]:" "")
=> ERROR: "Not a tramp file name: "
The desired result can be obtained with this call
(swap the two args):
(file-name-all-completions "" "/telnet:[EMAIL PROTECTED]:")
=> OK
========
(file-name-all-completions "/telnet:[EMAIL PROTECTED]:/tmp" "")
=> ERROR: "Not a tramp file name: "
The desired result can be obtained with this call
(swap the two args):
(file-name-all-completions "" "/telnet:[EMAIL PROTECTED]:/tmp")
=> OK
========
Now, one would suppose that swapping the two args would work for
the first two forms above, but not so:
(file-name-all-completions "" "/telnet:")
=> ERROR: Login failed
(file-name-all-completions "/telnet:kfs@" "")
=> ERROR: Login failed
========
(file-name-all-completions "/kfs@" "")
=> OK
========
(file-name-all-completions "/[EMAIL PROTECTED]:" "")
=> ERROR: "Not a tramp file name: "
Swapping the args works here too:
(file-name-all-completions "" "/[EMAIL PROTECTED]:")
=> OK
========
(file-name-all-completions "/localhost:" "")
=> ERROR: "Not a tramp file name: "
Again swapping the args will work:
(file-name-all-completions "" "/localhost:")
=> OK
========
I have made ido adapt to all these strange rules, but it is not very
nice -- and I have to know whether /xxx: is a method or a host, since:
(file-name-all-completions "/telnet:" "")
=> OK
(file-name-all-completions "/localhost:" "")
=> FAILS
(file-name-all-completions "" "/telnet:")
=> FAILS
(file-name-all-completions "" "/localhost:")
=> OK
========
