Well, I figured it was the least I could do, since he's put so much effort into outshine, outorg, and navi-mode over the years. Be advised, although I am now the maintainer, I only comprehend a tiny fraction of them; I learn more about them when I need to fix something, which so far has hardly happened. :) > How can I collapse block-indented comments like a or b in the following?: > > ;; * Org > (defun foo () > ;; ** a > (bar) > ;; ** b > (beer)) > ;; * Calc > > orgstruct-mode supports it with orgstruct-heading-prefix-regexp set to > for example " *;;;* ". I don't think this is possible, or at least not easily. The outline-regexp variable says: Regular expression to match the beginning of a heading. Any line whose beginning matches this regexp is considered to start a heading. Note that Outline mode only checks this regexp at the start of a line, so the regexp need not (and usually does not) start with ‘^’. So I think you would need to modify outline-mode to do this. However, there are other ways to fold text besides outline/outline-minor-mode/outshine. You could probably do it fairly easily with the origami package. Or you could do what I do: I modify outline-regexp and outline-level so that the asterisks aren't even necessary. Instead, the heading level is set by how many semicolons there are, e.g.: ;; Regular comment ;;; Heading level 1 ;;;; Heading level 2 ... Then any comment that starts with 3 or more semicolons is indented to the left edge and becomes a collapsible heading, regardless of the indentation of the code under it. #+BEGIN_SRC elisp (defun ap/el-outline-level () (or ;; Commented outline heading (and (string-match (rx (* space) (group (one-or-more (syntax comment-start))) (one-or-more space)) (match-string 0)) (- (match-end 0) (match-beginning 0) 1)) ;; Lisp def heading ;; Add 8 (the highest standard outline level) to every keyword ;; heading (+ 8 (- (match-end 0) (match-beginning 0))))) (defun ap/el-mode-outline-hook () (setq outline-level 'ap/el-outline-level) (setq outline-regexp "\\(;;[;]\\{1,8\\} \\|\\((defun\\)\\)")) (add-hook 'emacs-lisp-mode-hook 'ap/el-mode-outline-hook) #+END_SRC It works well for me, and it doesn't even require outshine IIRC, just outline-minor-mode. I've tried to make this work in other languages too, like using the number of # characters for the outline level in shell scripts, but I failed miserably, so I use outshine for other languages. It's easier in elisp since Emacs already treats triple-semicolon comments as headings. > A bit less important for me: How can I turn off syntax highlighting of > headings, respectively generally in outshine.el? Well, the first thing that comes to mind is to unset the properties of the outline-level faces, but I'm not sure if you can do that per-buffer. So you might try removing the outline-font-lock-keywords or outline-font-lock-faces. Hope this helps. Adam
