convert region to html?

convert region to html?

[David O'Toole]

I am working on my blog extension for org-publish. I would like to
convert a region of text (say, between two markers) from org-mode
markup into html and then paste the resulting html into another buffer
where I am building a full page. I need to do this from a lisp
program. It says that org-export-as-html will export an active region
but I tried it and it doesn't work in a temp-buffer where
(buffer-file-name) is nil. Anyway, would it be hard to expose a
function like the following?

(defun org-export-region-to-html (beg end)
  "Convert region between BEG and END into HTML, placing the result
  into a new buffer. The new buffer is returned."
  ...
  ...

I did something similar for Muse recently.  I'm including the code
snippet in case it comes in handy.

;;;###autoload
(defun muse-publish-region (beg end &optional title style)
  "Apply the given STYLE's markup rules to the given region.
The result is placed in a new buffer that includes TITLE in its name."
  (interactive "r")
  (when (interactive-p)
    (unless title (setq title (read-string "Title: ")))
    (unless style (setq style (muse-publish-get-style))))
  (let ((muse-publishing-current-style style)
        (muse-publishing-p t)
        (text (buffer-substring beg end))
        (buf (generate-new-buffer (concat "*Muse: " title "*"))))
    (with-current-buffer buf
      (insert text)
      (muse-publish-markup-buffer title style)
      (goto-char (point-min))
      (let ((inhibit-read-only t))
        (remove-text-properties (point-min) (point-max)
                                '(rear-nonsticky nil read-only nil))))
    (pop-to-buffer buf)))

Thanks for this idea, will be useful for many things.

- Carsten

4.75 will contain the following function:

(defun org-export-region-as-html (beg end &optional body-only buffer)
   "Convert region fron BEG to END in org-mode buffer to HTML.
If prefix arg BODY-ONLY is set, omit file header, footer, and table of
contents, and only produce the region of converted text, useful for
cut-and-paste operations.
If BUFFER is a buffer or a string, use/create that buffer as a target
of the converted HTML.  If BUFFER is the symbol `string', return the
produced HTML as a string and leave no buffer behind.  For example,
a Lisp program could call this function in the following way:

   (setq html (org-export-region-as-html beg end t 'string))

When called interactively, the output buffer is selected, and shown
in a window.  A non-interactive call will only retunr the buffer."

org-blog.el updated to v1.17

[David O'Toole]

Available from http://dto.freeshell.org/e/org-blog.el

This is the first usable release of org-blog. Instructions for setup
and use are in the file's commentary. It requires org-mode at least
4.75 (very recent, see quoted posts below.)

You can see an example of the output at http://dto.freeshell.org/blog/
and the generated XML at http://dto.freeshell.org/blog/blog.xml

Features: 

  - write blog posts in org-mode syntax
  - juggle multiple posts while writing, publish in any order when finished
  - RSS 2.0 file. Now you can be on planet.emacsen.org!
  - "blogroll" (not well-tested)

Re: org-blog.el v1.17 and org-publish-org-to-html

[Rick Moynihan]

Hi,

I was using the version with org-mode (4.75) which seems to be the same 
as the one on your site.  Anyway, It seems like I was mistaken and 
org-publish-org-to-html is defined, it's just that the function wasn't 
interactive and I was expecting it to be.  I've not had chance to look 
much further into org-blog than this, but I have managed to get it to 
output some HTML.

On another note, I've not really used org-publish before, and have just 
seen that it supports multiple projects.  Is it possible to configure a 
project that is a 'single.org' file, which is in a folder of org files. 
  What I'd like is to be able to publish only single.org, and none of 
the others.  Is it possible to include *ONLY* this file?

Thanks again,

R.
