Binding a key to an ibuffer filter

Binding a key to an ibuffer filter

[etay.meiri]

Hi,

I'm trying to bind a key to a filter in ibuffer-mode. I created a
filter to display only C/C++ source files and it works ok manually (I
can switch to it using ibuffer-switch-to-saved-filter). I also added
the following code to .emacs:

(defun ibuffer-display-source-files ()
  (ibuffer-switch-to-saved-filter "c"))

(define-key ibuffer-mode-map [f1] 'ibuffer-display-source-files)

However, when I click F1 in ibuffer I get the following error:

Wrong type argument: commandp, ibuffer-display-source-files

Any idea?

Thanks,

The error message is telling you that `ibuffer-display-source-files' is not a
command. A command in Emacs is a function that has an `interactive' spec. So do
this:

(defun ibuffer-display-source-files ()
  (interactive) ; <==== MISSING
  (ibuffer-switch-to-saved-filter "c"))

Consider also adding a doc string, for your users. ;-)

Thanks a lot.
Looks like some progress was made.
Now when I click F1 I get an error: "Symbol's function definition is
void: c"

My filter definition is as follow:

'(ibuffer-saved-filters (quote (("c" ((mode . c++-mode))) ("gnus" ((or
(mode . message-mode) (mode . mail-mode) (mode . gnus-group-mode)
(mode . gnus-summary-mode) (mode . gnus-article-mode))))
("programming" ((or (mode . emacs-lisp-mode) (mode . cperl-mode)
(mode . c-mode) (mode . java-mode) (mode . idl-mode) (mode . lisp-
mode)))))))

And I'm calling the switch function using:

(ibuffer-switch-to-saved-filters "c")

Maybe I'm not passing the parameter correctly?

Thanks,

-Etay

I'm not familiar with Ibuffer; perhaps someone else can help here. The error
message is telling you that `c' is not a function.

If someone else doesn't have a suggestion, try: (1) loading the source files
(e.g. ibuf-ext.el), not the byte-compiled files (e.g. ibuf-ext.elc), and then
(2) `M-x debug-on-entry RET ibuffer-switch-to-saved-filters'. Then step through
the debugger using `d' and `c', to see where the problem is.
