Keyboard macro and regexp syntax search

Keyboard macro and regexp syntax search

[spamfilteraccount]

Here's a key sequence which searches a whitespace character with a non-
whitespace character after it and moves right to terminate the search
there (just an example):

M-C-s	\s-\S- <right>


According to the macro editor it is recorded like this:

;; Keyboard Macro Editor.  Press C-c C-c to finish; press C-x k RET to
cancel.
;; Original keys: M-C-s \ s \ S <right>

Command: last-kbd-macro
Key: none

Macro:

M-C-s			;; isearch-forward-regexp
\			;; self-insert-command
s			;; self-insert-command
\			;; self-insert-command
S			;; self-insert-command
<right>			;; forward-char-nomark



The dash (-) character is missing after the syntax matcher (\s and
\S), so the macro doesn't work at playback. Is it a bug?

It works as expected for me, running Emacs 22.1.1:

;; Keyboard Macro Editor.  Press C-c C-c to finish; press C-x k RET to cancel.
;; Original keys: M-C-s \ s- \ S- <right>

Command: last-kbd-macro
Key: none

Macro:

M-C-s			;; isearch-forward-regexp
\			;; self-insert-command
s-			;; self-insert-command * 2
\			;; self-insert-command
S-			;; self-insert-command * 2
<right>			;; forward-char

Can you reproduce the problem when you launch Emacs with no init files
(i.e., emacs -Q)?

Yes. It seems the i-search and dash interaction is problematic. A
simple macro for searching for a dash:

;; Keyboard Macro Editor.  Press C-c C-c to finish; press C-x k RET to
cancel.
;; Original keys: C-s <right>

Command: last-kbd-macro
Key: none

Macro:

C-s			;; isearch-forward
<right>			;; forward-char

The dash is missing after C-s.


A macro which inserts a dash character into the buffer works. I tested
it.

Looks like it, but please try starting from

   emacs -Q

If the problem persists then report it as a bug.
