cannot call-last-kbd-macro on named macro

cannot call-last-kbd-macro on named macro

[james.kingston]

GNU Emacs 21.4.1....

I have saved some keyboard macros using insert-kbd-macro into my
.emacs, like the following:

(fset 'toggle-next-perlsub
   [?\C-\M-s ?\\ ?b ?s ?u ?b ?\\ ?b ?\C-m ?\C-\M-s ?{ ?\C-m ?\M-x ?f ?o
?l ?d ?- ?d ?w ?i ?m ?- ?t ?o ?g ?g ?l ?e return])

I can M-x fold-next-perlsub if I want to run the macro, but I cannot
then run call-last-kbd-macro (which I have bound to an F-key)... it's
as if the macro is loaded as a function rather than a kbd macro.

As a workaround I could change the binding of the F-key to call my
named macro, but then I wouldn't be able to use the macros with
apply-macro-to-region-lines... So is there some way to push a named
macro onto some sort of macro stack so I can use the macro commands
with my macro?

As a workaround... I realized that I could define a kbd macro that
called my named macro...
C-x ( M-x toggle-next-perlsub C-x )

heh... it works, I guess

No, a keyboard macro is also an interactive function (i.e. a command).
But `M-x call-last-kbd-macro' (which is already bound to `C-x e', not
any harder to type than <Fn>) calls the last keyboard macro that you
defined interactively with `C-x (', not the last macro you defined
programatically with `fset'.

If you want to run the last keyboard macro that you called via `M-x'
again, try `M-x M-p'.

First, note that `M-x apply-macro-to-region-lines' is available as
`C-x C-k r' in Emacs 22.  But in previous versions I used `C-x E':

(global-set-key "\C-xE" 'apply-macro-to-region-lines) ; uppercase `E'

To call named macros via apply-macro-to-region-lines, I use `C-u ...':

(defadvice apply-macro-to-region-lines (before read-named-macro activate)
   "With a prefix arg, read a named macro to apply (instead of the last 
macro)."
   (interactive
    (list (region-beginning)
          (region-end)
          (if current-prefix-arg
              (read-command "Name of keyboard macro to apply: ")))))

I'd have to disagree that C-x e is easier to type than F5. I find that
if I tried typing it a bunch of times in a row I'd eventually hit C-x
C-e and land in the backtrace buffer... but thank you for clearing that
all up.

A very nice feature of CVS emacs is that once you type C-x e to
execute a macro, you can re-execute it by typing e.

Wow, there are a lot of nice features in Emacs 22 (see etc/NEWS):

** The new kmacro package provides a simpler user interface to
emacs' keyboard macro facilities.

Basically, it uses two function keys (default F3 and F4) like this:
F3 starts a macro, F4 ends the macro, and pressing F4 again executes
the last macro.  While defining the macro, F3 inserts a counter value
which automatically increments every time the macro is executed.

There is now a keyboard macro ring which stores the most recently
defined macros.

The C-x C-k sequence is now a prefix for the kmacro keymap which
defines bindings for moving through the keyboard macro ring,
C-x C-k C-p and C-x C-k C-n, editing the last macro C-x C-k C-e,
manipulating the macro counter and format via C-x C-k C-c,
C-x C-k C-a, and C-x C-k C-f.  See the commentary in kmacro.el
for more commands.

The normal macro bindings C-x (, C-x ), and C-x e now interfaces to
the keyboard macro ring.

The C-x e command now automatically terminates the current macro
before calling it, if used while defining a macro.

In addition, when ending or calling a macro with C-x e, the macro can
be repeated immediately by typing just the `e'.  You can customize
this behavior via the variables kmacro-call-repeat-key and
kmacro-call-repeat-with-arg.

Keyboard macros can now be debugged and edited interactively.
C-x C-k SPC steps through the last keyboard macro one key sequence
at a time, prompting for the actions to take.

Yes, that is really neat! How is it done? Programatically I mean. It
would be cool to be able to do the same with other commands (buffer
cycling, for example, which is now by default on C-x <left> and C-x
<right>).

The function kmacro-call-macro in kmacro.el might be a good
starting point.

Aaaaa... After looking at that piece of code for a while I noticed
this:

	(if (equal repeat-key (read-event))

So *that* is what it does, read another event and then handles that.

Cool!

Don't ask me why I did not bother to look this up myself, it was right
there, only a C-h k away... :)
