I'm writing a little helper function for use when I'm starting work on a
particular long-term writing project. Basically I found myself doing the
same little ritual of commands two or three times a day, and I got tired
of it. Here's what I've got so far, it's pretty self-explanatory. The "my-"
variables are set elsewhere.
#+BEGIN_SRC emacs-lisp
(defun my-project-start ()
(interactive)
(delete-other-windows)
(find-file my-project-file)
;; here's where I go to the most recent Chapter heading
(org-narrow-to-subtree)
(split-window-horizontally)
(other-window 1)
(goto-char (point-max))
(read-abbrev-file my-project-abbrev-file)
)
#+END_SRC
The bit I'm missing is in the comment above. The file is full of
different headings, most (but not all) of which look like
* Chapter XXX
I've looked at the code for org-goto, but it's a wee bit complicated,
and I don't need to do things like pushing to the mark ring. My question
is, what's the simplest way to either:
1. Jump to the "Chapter" heading with the largest number
2. Jump to the bottom-most "Chapter" heading (the bottom-most heading is
not a Chapter)
Additionally, in this case is there any practical difference between
using narrowing or using an indirect buffer? I'm not doing anything but
writing…
Thanks!
Eric

Hi Eric,
If your chapters are always level 1 headings you can do something like
this:
--8<---------------cut here---------------start------------->8---
(defun bh/jump-to-last-level-1-heading ()
(interactive)
(goto-char (point-max))
(while (org-up-heading-safe)))
--8<---------------cut here---------------end--------------->8---
HTH,

Thanks for the pointers! A =while= form with no body wasn't
something that had occured to me, that's pretty useful. The final
command, which does just what I want, is below.
Eric
#+begin_src emacs-lisp
(defun my-project-start ()
(interactive)
(delete-other-windows)
(find-file my-project-file)
(goto-char (point-max))
(while (org-up-heading-safe))
(while (not (looking-at "\\* Chapter"))
(org-backward-same-level 1))
(org-narrow-to-subtree)
(split-window-horizontally)
(other-window 1)
(show-subtree)
(goto-char (point-max))
(abbrev-mode 1)
(read-abbrev-file my-project-abbrev-file)
)
#+end_src
