I did try something this:
#+begin_src emacs-lisp
(defun my-func ()
(with-current-buffer (get-buffer-create "my-capture-buffer")))
(defun my-hook ()
(with-current-buffer
(try-completion "CAPTURE" (mapcar #'buffer-name (buffer-list)))
(let ((content (buffer-string)))
(kill-buffer)
content)))
(defun my-read-string ()
(let ((org-capture-templates
`(("s" "string" plain (function my-func))))
(org-capture-before-finalize-hook #'my-hook))
(org-capture nil "s")))
#+end_src
But that does not work well, because capture will put buffer it is called from
as original buffer and write to that one. To prevent that I can call capture
from a temporary buffer:
#+begin_src emacs-lisp
(defun my-read-string ()
(with-current-buffer (get-buffer-create "my-capture-buffer")
(let ((org-capture-templates
`(("s" "string" plain (function ignore))))
(org-capture-before-finalize-hook #'my-hook))
(org-capture nil "s"))))
#+end_src
but than capture complains about the buffer not being a file buffer, despite the
before finalize hook. I could point it to some temp file like /tmp/my-capture,
by
manipulating capture plist myself, but it seems to be too expensive to create a
temp file just for a hack to read a string form a buffer. There is probably some
other way, but I give up here, especially since you point our
read-string-from-buffer :)
Anyway, thanks for the input and help.
