I have this little LaTeX helper function:
(defun my--insert-chord (chord)
"Prompt for a CHORD and insert it at point. TODO: make it agnostic to the package used."
(interactive "MChord: ")
(insert (concat "\\[" chord "]")))
that works like a breeze.
Now, I want to integrate with isearch. I have this other helper function (taken from this question and in turn from Endless Parentheses):
(defun isearch-exit-other-end ()
"Exit isearch, at the opposite end of the string."
(interactive)
(goto-char isearch-other-end)
(isearch-exit))
Now, I want to combine the two and bind themto a key. Since it's a one-off use, IIUC it makes sense to use a lambda:
(define-key isearch-mode-map (kbd "C-M-c")
(lambda () (interactive) (isearch-exit-other-end) (call-interactively (my--insert-chord))))
But Emacs complains:
Debugger entered--Lisp error: (wrong-number-of-arguments (lambda (chord) "Prompt for a CHORD and insert it at point. TODO: m..." (interactive "MChord: ") (insert (concat "\\[" chord "]"))) 0)
my--insert-chord()
(call-interactively (my--insert-chord))
(lambda nil (interactive) (isearch-exit-other-end) (call-interactively (my--insert-chord)))()
funcall-interactively((lambda nil (interactive) (isearch-exit-other-end) (call-interactively (my--insert-chord))))
command-execute((lambda nil (interactive) (isearch-exit-other-end) (call-interactively (my--insert-chord))))
Now, of course I haven't provided the correct number of arguments, that's because my--insert-chord should prompt for one. How can I achieve this? Of course, I can duplicate the interactive string in the lambda, but I suspect there's a clever way, since this would lead to code duplication. My Google-fu only provided examples to pass arguments via code, but that's not what I want. If this is a dup I apologize, and I will gratefully taken redirection.
Thanks!
