See below. I put the same text also at http://www.emacswiki.org/emacs/Comments_on_outline-magic.el. The version 0.9 (or 20120505.1234 from MELPA) doesn’t work for me. In some files (e.g. outline-magic.el itself), when the point is at the beginning of the buffer and I run ‘outline-cycle’, the whole buffer gets hidden. Subsequent runs of ‘outline-cycle’ fail and everything remains hidden. The failure is caused by (error “before first heading”) called from `outline-back-to-heading`. I run GNU Emacs 24.3.1 (x86_64-pc-linux-gnu, GTK+ Version 3.4.2) of 2013-04-13 on trouble, modified by Debian. This patch fixes the problem. diff --git a/outline-magic.el b/outline-magic.el index 52ca5cf..81331c5 100644 --- a/outline-magic.el +++ b/outline-magic.el @@ -266,7 +266,13 @@ them set by set, separated by a nil element.

I kind of took over outline-magic.el from Carsten when I merged it into outshine.el and he asked me if I want to be the new maintainer. I remember I hit the same bug like you and fixed it - but nothing else ;) There is a version 0.9.1 available on github: ,-------------------------------------- | https://github.com/tj64/outline-magic `-------------------------------------- and I think its this version I merged into outshine.el ,--------------------------------- | https://github.com/tj64/outshine `--------------------------------- and since outshine does not have the problem you describe any more, I conclude that its fixed in version 0.9.1 of outline-magic too. May be you can check it out? PS If you use outshine.el in combination with outorg.el and navi-mode.el (all available in my github account) you get everything outline-magic offers (since it is merged into outshine.el) + the extensions from out-xtra.el + many new ideas and features, see this tutorial ,----------------------------------------------------------- | http://orgmode.org/worg/org-tutorials/org-outside-org.html `----------------------------------------------------------- on Worg (there are links to related screencasts on youtube at the end of the page).

I think I'll give it a try. If you like Org-mode, it is for you - it blurs the line between Org-mode and programming language major modes. I organize all my source-code files like Org-mode files, and with outshine they just look and feel like Org-mode buffers. But outshine.el is not a complete replacement for outline-magic.el, although all of its functionality is merged into outshine, otherwise support for the latter could be dropped. outshine.el is based on a simple but powerful idea: ,---------------------------------------------- | headlines are outcommented Org-mode headlines `---------------------------------------------- using whatever comment-syntax the programming-language major-mode at hand defines. There is only one special case supported: - oldstyle Emacs Lisp headlines ,--------------------------- | ;;;; Second Level Header `--------------------------- instead of "outshine-style" ,---------------------------- | ;; ** Second Level Header `---------------------------- Thus, if you do not adopt this basic idea and use outline/outline-magic in other ways (i.e. you structure your source-code files without using outcommented Org-mode headlines), you cannot use outshine.el. But you still can benefit from outline-magic's extension to outline mode, so outline-magic.el should be maintained independently from outshine.el. >> There is a version 0.9.1 available on github: >> >> ,-------------------------------------- >> | https://github.com/tj64/outline-magic >> `-------------------------------------- > > Hmm, what about modifying the pages on Emacs Wiki [1], [2] to reflect > the location of the new version.

I wanted to promote outshine.el, outorg.el and navi-mode.el on Emacs Wiki, but I was turned off by the fact that they publish my full name together with my IP address. I find that strange. PS Did you test the new version - does it fix the bug you encountered?. Would be nice to get some confirmation that things work before announcing them on Emacs Wiki. -- cheers, Thorsten ^ permalink raw reply [flat|nested] 6+ messages in thread

I think I'll give it a try. I've just looked at outshine.el and I like the idea. What I don't like is that it does not work in buffers without "modern" headers such as LaTeX, programming languages etc. where outline-magic worked. In my opinion, the strength of outline-magic is that it works the same in all major modes that set outline-regexp reasonably. From the quick look at the code, it seems that you try to detect the presence of "modern" headers in files (at least elisp files). It would be nice if you could change outshine to work like outline-magic when modern headers are not detected. I also miss the functionality to fold elisp defuns with outshine. Therefore, I'll stay with outline-magic. The bug I reported is present even in your version so I've sent you a pull request over github.

With outline/outline-magic you can define whatever you want as a headline. Outshine tries to make source-code files look&feel like Org-mode files, and it actually works with all kinds of major-modes (even those not yet written), but not with all kinds of headline styles (only outcommented Org-mode headers). > From the quick look at the code, it seems that you try to detect the > presence of "modern" headers in files (at least elisp files). It would > be nice if you could change outshine to work like outline-magic when > modern headers are not detected. Just like the Org-mode maintainers decided that the asteriks ,--------- | * Header `--------- is hardcoded syntax in Org-mode, I decided to only cover the case that users structure their files with outcommented Org-mode headers. This keeps things simple and generic. If users want it only for some major-modes and others not, they can still use outline/outline-magic without loading outshine in the major-mode hook. I'm afraid it would be quite difficult to fall-back to plain outline/outline-magic once outshine was loaded in the case that no 'modern' headers are detected, so I would prefer to rather not touch this. > I also miss the functionality to fold elisp defuns with outshine. I Org-mode, headlines are folded, not their content, and in an elisp buffer structured with outshine headers, the defuns are content, not headlines. But navi-mode.el gives you something similar, and much more: 'M-s n' for opening the navi-buffer (e.g. in outshine.el buffer) then 'f' for showing functions and macros: ,-------------------------------------------------------------------------- | 48 matches for "^[[:space:]]*(def[mau][^e][a-z]* " in buffer: outshine.el | 204:(defun outshine-compatible-face (inherits specs) | 468:(defmacro outshine-define-key-with-fallback | 501:(defun outshine-chomp (str) | 511:(defun outshine-set-outline-regexp-base () | 524:(defun outshine-normalize-regexps () | 539:(defun outshine-modern-header-style-in-elisp-p (&optional buffer) | 550:(defun outshine-calc-comment-region-starter () | 560:(defun outshine-calc-comment-padding () ... `-------------------------------------------------------------------------- 'v' for showing variables: ,--------------------------------------------------------------------------- | 39 matches for "^[[:space:]]*(def[vcgf][^l][a-z]+ " in buffer: outshine.el | 123:(defconst outshine-version "1.0" | 127:(defconst outshine-level-faces | 132:(defconst outshine-outline-heading-end-regexp "\n" | 136:(defconst outshine-oldschool-elisp-outline-regexp-base "[;]+" | 142:(defvar outline-minor-mode-prefix "\M-#" | 150:(defvar outline-promotion-headings nil ... `--------------------------------------------------------------------------- '3' for showing headers up to level 3: ,--------------------------------------------------------------------- | 34 matches for "^;; \*\*?\*?

Yes, you are right - I always orderly start with level 1 when structuring my files, so I did not notice.
