;;;; Commentary
;;;;; About outorg
;; Outorg is for editing comment-sections of source-code files in
;; temporary Org-mode buffers. It turns conventional
;; literate-programming upside-down in that the default mode is the
;; programming-mode, and special action has to be taken to switch to the
;; text-mode (i.e. Org-mode).
;; Outorg depends on Outshine, i.e. outline-minor-mode with outshine
;; extensions activated. An outshine buffer is structured like an
;; org-mode buffer, only with outcommented headlines. While in
;; Org-mode text is text and source-code is 'hidden' inside of special
;; src-blocks, in an outshine buffer source-code is source-code and
;; text is 'hidden' as comments.
;; Thus org-mode and programming-mode are just two different views on
;; the outshine-style structured source-file, and outorg is the tool
;; to switch between these two views. When switching from a
;; programming-mode to org-mode, the comments are converted to text
;; and the source-code is put into src-blocks. When switching back
;; from org-mode to the programming-mode, the process is reversed -
;; the text is outcommented again and the src-blocks that enclose the
;; source-code are removed.
;; When the code is more important than the text, i.e. when the task
;; is rather 'literate PROGRAMMING' than 'LITERATE programming', it is
;; often more convenient to work in a programming-mode and switch to
;; org-mode once in a while than vice-versa. Outorg is really fast,
;; even big files with 10k lines are converted in a second or so, and
;; the user decides if he wants to convert just the current subtree
;; (done instantly) or the whole buffer. Since text needs no session
;; handling or variable passing or other special treatment, the outorg
;; approach is much simpler than the Org-Babel approach. However, the
;; full power of Org-Babel is available once the *outorg-edit-buffer*
;; has popped up.
;;;;; Usage
;; Outorg (like outshine) assumes that you set
;; `outline-minor-mode-prefix' in your init-file to 'M-#':
;; #+BEGIN_EXAMPLE
;; ;; must be set before outline is loaded
;; (defvar outline-minor-mode-prefix "\M-#")
;; #+END_EXAMPLE
;; Outorg's main command is
;; #+begin_example
;; M-# # (or M-x outorg-edit-as-org)
;; #+end_example
;; to be used in source-code buffers where `outline-minor-mode' is
;; activated with `outshine' extensions. The Org-mode edit-buffer popped
;; up by this command is called *outorg-edit-buffer* and has
;; `outorg-edit-minor-mode' activated, a minor-mode with only 2 commands:
;; #+begin_example
;; M-# (outorg-copy-edits-and-exit)
;; C-x C-s (outorg-save-edits-to-tmp-file)
;; #+end_example
;; If you want to insert Org-mode source-code or example blocks in
;; comment-sections, i.e. you don't want outorg to remove the
;; enclosing blocks, simply outcomment them in the outorg-edit buffer
;; before calling `outorg-copy-edits-and-exit'.
;; Note that outorg only treats 'active' src-blocks in a special way -
;; the blocks whose Babel language is equal to the major-mode of the
;; associated programming-mode buffer. All other (src-) blocks are
;; treated like normal text.
;; Note further that outorg uses example-blocks as 'fallback' when it
;; cannot find the major-mode of the programming-mode buffer in the
;; `org-babel-load-languages'. In this case you should not use
;; example-blocks for other tasks, since they will be removed when
;; exiting the *outorg-edit-buffer*, use e.g. quote-blocks or
;; verse-blocks instead.
;;;;; Installation
;; You can get outorg.el either from Github (see section MetaData) or
;; via MELPA. It depends on outshine.el, so you have to install and
;; configure outshine first to make outorg work.
;; Installation is easy, simply insert
;; #+begin_example
;; (require 'outorg)
;; #+end_example
;; in your init file. When you use navi-mode.el too, the third Outshine
;; library, it suffices to (require 'navi), since it requires the other
;; two libraries.
;;;;; Bugs and Shortcomings
;; Outorg started out purely line-based, it only worked with
;; 'one-line' comments, i.e. with comment-sections like those produced
;; by `comment-region' (a command that comments or uncomments each
;; line in the region). It was enhanced later on to recognize comment
;; regions too, i.e. those special multi-line comments found in many
;; programming languages. But using outorg on such multi-line comments
;; will probably change their syntax back to 'single-line', whenever
;; `comment-region' uses this style.
;;;;; Tests
;; A special kind of test has been developed for outorg using the
;; `ert-buffer' library, the so called 'conversion test'. It has the
;; following steps:
;; 1. programming-mode -> org-mode
;; 2. edit in org-mode, store undo-information
;; 3. org-mode -> programming-mode
;; 4. programming-mode -> org-mode (again)
;; 5. undo edits
;; 6. org-mode -> programming-mode (again)
;; After these 4 conversions, the original programming-mode buffer
;; must be unchanged when the conversion process is perfect, i.e. does
;; not introduce any changes itself. See `outorg-test.el' for details.
;;;;; Emacs Version
;; Outorg works with GNU Emacs 24.2.1 or later. No attempts of testing
;; with older versions or other types of Emacs have been made (yet).

(defun outorg-prepare-iorg-edit-buffer-for-editing ()
"Prepare a buffer opened with `edit' from iorg-scrape for outorg.
This function assumes that a PicoLisp symbol that contains the
text of an Org-mode file (fetched from an iOrg application) has
been loaded into a PicoLisp `edit' buffer. It transforms the
buffer content to a `outshine' compatible format, such that
`outorg-edit-as-org' can be applied on it.
In particular, this function assumes that the original `edit'
buffer has the following format
;; #+begin_quote
txt \"<content-org-file>\"
\(********\)
;; #+end_quote
and that the text must be transformed to a format that looks
somehow like this
;; #+begin_quote
## #+DESCRIPTION txt
\[## #+<OPTIONAL-EXPORT-HEADERS>\]
## * Org-file
## Content
\(********\)
;; #+end_quote
i.e. the symbol-name 'txt' is converted to a #+DESCRIPTION keyword
