How to disable flymake in tramp buffers

How to disable flymake in tramp buffers

[Gary]

I'm pretty tired of the messages telling my flymake has been switched
off every time I visit a file on a remote host. Is there any way to
ensure it is only switched on for local files?

Maybe you can tweak `flymake-allowed-file-name-masks'.

Best regards, Michael.

Why is it switched off?
For which modes does it do that?

"Error (flymake): Flymake: Configuration error has occurred while
running (php -f test_flymake.php -l). Flymake will be switched OFF"

It is a known problem with flymake when opening files on a remote
host. It uses the wrong function to start the checking process, I
believe. Michael Albinus knows more than I do, it was one of his posts I
found explaining it :) - see
http://groups.google.com/group/gnu.emacs.help/browse_thread/thread/dda14275ce2b8b02/aa9533ce3666e0ca
Sadly it looks like it hasn't even been changed in CVS :(

Maybe you can use something like (in the hook)
--8<---------------cut here---------------start------------->8---
(when (not (tramp-file-name-p current-file-name))
    ; start flymake
--8<---------------cut here---------------end--------------->8---
(not tested)

IIRC, I've asked for a bug report. Nobody did report, consequently
nobody did work on it.

However, the change is not risky. I have committed the following patch
to the Emacs 23 branch:

  	  (set-process-filter process 'flymake-process-filter)
            (push process flymake-processes)
--8<---------------cut here---------------end--------------->8---

Could somebody, please, check, whether this is TRT? I do not use flymake.

Best regards, Michael.
