Using “M-x insert-kbd-macro” can insert an incorrect kmacro form for a
named macro, while still correctly inserting the “last-kbd-macro”.
To see this, we’ll define a macro that simply inserts the HTML string
“<b>hello</b>” (press F3, type the previous string, then press F4).
We’ll name this macro “bold-hello” using “C-x C-k n”.
Inserting the definition to the last macro (using “M-x insert-kbd-macro”
and leaving the prompt blank) returns:
(setq last-kbd-macro
(kmacro "< b > H e l l o < / b >"))
Inserting the definition to “bold-hello” (using “M-x insert-kbd-macro”
and typing “bold-hello” at the prompt) returns:
(defalias 'bold-hello
(kmacro "<b> H e l l o < / b >"))
Notice the difference in “< b >” vs “<b>”. The “bold-hello” command
doesn’t work, printing the message:
“After 0 kbd macro iterations: Keyboard macro terminated by a command ringing
the bell”
I think this may have to do with the use of “key-parse” in “kmacro” (see
“(find-function 'kmacro)”).
(key-parse "<b>hello</b>") returns
“[b 104 101 108 108 111 60 47 98 62]”
but
(macro--string-to-vector "<b>hello</b>") returns
“[60 98 62 104 101 108 108 111 60 47 98 62]”
The latter form is used in “insert-kbd-macro” when inserting
“last-kbd-macro”.
You can also quickly replicate the issue by evaluating the following
form:
(progn
(setq last-kbd-macro "<b>hello</b>")
(kmacro-name-last-macro 'bold-hello)
(let ((temp-buffer (generate-new-buffer "*macros*")))
(with-current-buffer temp-buffer
(insert-kbd-macro (intern ""))
(insert-kbd-macro 'bold-hello))
(display-buffer temp-buffer)))
