|

|
||||
The =docco= tool (see http://jashkenas.github.com/docco/) generates
|
||||
HTML from JavaScript source code providing an attractive side-by-side
|
||||
display of source code and comments. This file (see [[http://orgmode.org/w/?p=org-mode.git;a=blob_plain;f=contrib/scripts/org-docco.org;hb=HEAD][org-docco.org]])
|
||||
generates the same type of output from Org-mode documents with code
|
||||
embedded in code blocks.
|
||||
|
||||
The way this works is an Org-mode document with embedded code blocks
|
||||
is exported to html using the standard Org-mode export functions.
|
||||
This file defines a new function named =org-docco-buffer= which, when
|
||||
added to the =org-export-html-final-hook=, will be run automatically
|
||||
as part of the Org-mod export process doccoizing your Org-mode
|
||||
document.
|
||||
|
||||
A pure source code file can be extracted (or "/tangled/") from the
|
||||
Org-mode document using the normal =org-babel-tangle= function. See
|
||||
[[http://orgmode.org/manual/Working-With-Source-Code.html][Working With Source Code]] chapter of the Org-mode manual for more
|
||||
information on using code blocks in Org-mode files.
|
||||
|
||||
*Disclaimer*: this currently only works on /very/ simple Org-mode
|
||||
files which have no headings but rather are just a collection of
|
||||
alternating text and code blocks. It wouldn't be difficult to
|
||||
generalize the following code so that it could be run in particular
|
||||
sub-trees but I simply don't have the time to do so myself, and this
|
||||
version perfectly satisfies my own limit needs. I make no promises to
|
||||
support this code moving forward. /Caveat Emptor/

#+end_src
|
||||
|
||||
The =cl= package provides all of the state-changing functions used
|
||||
below e.g., =push= and =incf=. It looks like a namespace-safe version
|
||||
of =cl= may soon be permissible for use in official Emacs packages.
|
||||
#+begin_src emacs-lisp
|
||||
;;; Code:
|
||||
(require 'cl)
|
||||
#+end_src
|
||||
|
||||
This is a function which returns the buffer positions of matching
|
||||
regular expressions. It has two special features...
|
||||
1. It only counts matched instances of =beg-re= and =end-re= which are
|
||||
properly nested, so for example if =beg-re= and =end-re= are set to
|
||||
=(= and =)= respectively and we run this against the following,
|
||||
: 1 2 3 4 5 6
|
||||
: | | | | | |
|
||||
: v v v v v v
|
||||
: (foo (bar baz) (qux) quux)
|
||||
it will return 1 and 6 rather than 1 and 3.
|
||||
2. It uses [[www.gnu.org/s/emacs/manual/html_node/elisp/Markers.html][markers]] which save their position in a buffer even as the
|
||||
buffer is changed (e.g., by me adding in extra HTML text).
|
||||
#+begin_src emacs-lisp
|
||||
(defun org-docco-balanced-re (beg-re end-re)
|
||||
"Return the beginning and of a balanced regexp."
|
||||
(save-excursion
|
||||
(save-match-data
|
||||
(let ((both-re (concat "\\(" beg-re "\\|" end-re "\\)"))
|
||||

||||

|
||||

#+end_src
|
||||
|
||||
This ugly large function does the actual conversion. It wraps the
|
||||
entire main content =div= of the exported Org-mode html into a single
|
||||
large table. Each row of the table has documentation on the left side
|
||||
and code on the right side. This function has two parts.
|
||||
1. We use =(org-docco-balanced-re "<div" "</div>")= to find the
|
||||
beginning and end of the main content div. We then break up this
|
||||
div at =<pre></pre>= boundaries with multiple calls to
|
||||
=(org-docco-balanced-re "<pre class\"src" "</pre>")=.
|
||||
2. With all documentation/code boundaries in hand we step through the
|
||||
buffer inserting the table html code at boundary locations.
|
||||
#+begin_src emacs-lisp
|
||||
(defun org-docco-buffer ()
|
||||
"Call from within an HTML buffer to doccoize it."
|

(let ((table-start "<table>\n")
|
||||
(doc-row-start "<tr><th class=\"docs\">\n") (doc-row-end "</th>\n")
|
||||
(code-row-start " <td class=\"code\">\n") (code-row-end "</td></tr>\n")
|
||||
(table-end "</table>" )
|
||||

|

|

|

|
||||
(push (cdr next) transition-points))
|
||||
(goto-char (cdr pair))
|
||||
(push (and (re-search-backward "</div>" nil t) (point-marker))
|
||||
transition-points)
|
||||
;; collected transitions, so build the table
|

(setq transition-points (nreverse transition-points))
|

(goto-char (pop transition-points))
|
||||
(insert table-start doc-row-start)
|
||||
(while (> (length transition-points) 1)
|
||||
(goto-char (pop transition-points))
|
||||
(insert doc-row-end code-row-start)
|
||||
(goto-char (pop transition-points))
|

(insert code-row-end doc-row-start))
|

(goto-char (pop transition-points))
|
||||
(insert code-row-end table-end)
|
||||
(unless (null transition-points)
|
||||
(error "leftover points")))))))
|
||||
#+end_src
|
||||
|
||||
We'll use Emacs [[http://www.gnu.org/software/emacs/manual/html_node/emacs/Specifying-File-Variables.html][File Local Variables]] and the
|
||||
=org-export-html-final-hook= to control which buffers have
|
||||
=org-docco-buffer= run as part of their export process.
|
||||
#+begin_src emacs-lisp
|
||||
(defvar org-docco-doccoize-me nil
|
||||
"File local variable controlling if html export should be doccoized.")
|
||||
(make-local-variable 'org-docco-doccoize-me)
|
||||
#+end_src
|
||||
|
||||
A simple function will conditionally process HTML output based on the
|
||||
value of this variable.
|
||||
#+begin_src emacs-lisp
|
||||
(defun org-docco-buffer-maybe ()
|
||||
(when org-docco-doccoize-me (org-docco-buffer)))
|
||||
#+end_src
|
||||
|
||||
Finally this function is added to the =org-export-html-final-hook=.
|
||||
#+begin_src emacs-lisp
|
||||
(add-hook 'org-export-html-final-hook #'org-docco-buffer-maybe)
|
||||
#+end_src
|
||||
|
||||
That's it. To use this simply;
|
||||
1. Checkout this file from https://github.com/eschulte/org-docco,
|
||||
: git clone git://github.com/eschulte/org-docco.git
|
||||
and open it using Emacs.
|
||||
2. Tangle =org-docco.el= out of this file by calling
|
||||
=org-babel-tangle= or =C-c C-v t=.
|
||||
3. Load the resulting Emacs Lisp file.
|
||||
4. Execute the following in any Org-mode buffer to add file local
|
||||
variable declarations which will enable post-processed with
|
||||
=org-docco-buffer=.
|
||||
: (add-file-local-variable 'org-export-html-postamble nil)
|
||||
: (add-file-local-variable 'org-export-html-style-include-default nil)
|
||||
: (add-file-local-variable 'org-docco-doccoize-me t)
|
||||
And add the following style declaration to make use of the
|
||||
=docco.css= style sheet taken directly from
|
||||
https://github.com/jashkenas/docco.
|
||||
: #+Style: <link rel="stylesheet" href="docco.css" type="text/css">
|
||||
|
||||
#+begin_src emacs-lisp
|
||||
(provide 'org-docco)
|
||||
;;; org-docco.el ends here
|
||||
#+end_src
|
||||
|
||||
# Local Variables:
