Re: [O] [patch] ox-latex.el: support for pgf files

2013-05-21 Thread Nicolas Goaziou

Hello,

Rasmus ras...@gmx.us writes:

 This patch adds support for pgf files.  pgf is the machine upon which
 tikz is build.  For instance matplotlib (of Python) and printpgf (of
 Octave) both produces pgf files.  It's just a question of recognizing
 the extension.  With this patch the following document exports
 correctly:

 #+TITLE: PGF test
 #+LATEX_HEADER: \usepackage{pgf}
 #+BEGIN_SRC emacs-lisp :exports none
   (set (make-local-variable 'org-latex-pdf-process)
'(xelatex -pdf %f))
 #+END_SRC
 #+BEGIN_SRC python :results raw :exports results
   from matplotlib import pylab as plt
   x, y = plt.rand(2)
   plt.scatter(x, y)
   fig = test.pgf
   plt.savefig(fig) ## utf8 by default
   return(.join([[[file:, fig, ]]]))
 #+END_SRC

Applied. Thank you.

 Hi,
 
 I'd like to commit the following patch which improves htmlize's handling
 of svg image overlays.  I couldn't find an upstream for htmlize, is it
 appropriate to patch htmlize in the Org-mode source tree?

 I found a bug in that the subject variable should be a list cf. the
 KOMA manual.  This patch fixes this.

 It's pretty complex for something so simple, and I might be inclined
 to admit to the put it in a LCO-file approach might be better.

I'd really like to have a second opinion on this. Viktor?

Re: [O] Starting emacs followed directly by org-agenda search and visiting file removes color formatting

Hi John,

 Sorry for the long title, but that's the summary! I fired up a fresh
 Emacs session and used =C-a s search-term RET= to navigate to a
 headline in the results by putting the cursor on the line and pressing
 RET.

 The file text was all black.

 If I visited the file directly, I had the typical color-coded text for
 headlines/keywords. I decided to replicate with a minimal config, and
 I was able to. Here's the context of the min config:

 #+begin_min-config
 ;; set load paths
 ;; set load dirs and global config options
 (add-to-list 'load-path ~/.elisp/org.git/lisp/)
 (add-to-list 'load-path ~/.elisp/org.git/contrib/lisp)
 #+end_min-config

 This was on a work file, and I couldn't initially replicate with a
 test file... but it appears it has to do with my header options.
 Here's the test file:

 #+begin_src org
 #+setupfile: ~/org/aux/setupfile.org
 #+options: :t num:t author:t creator:nil tags:t toc:nil date:t
 #+latex_header: \usepackage{lscape}
 #+latex_header: \usepackage{amsmath}

 * Test headline

 Some paragraph just to give me a keyword to search for

 ** Sub headline

 Some more text in the next headline
 #+end_src

 My process:
 - emacs -Q
 - M-x load-file RET ~/path/to/min-config RET
 - C-x C-f /path/to/file.org RET
 - C-c [ to add to agenda list
 - C-x C-k RET to kill buffer
 - M-x org-agenda RET s RET text RET
 - Navigate to test.org matching line RET
 - File looks like attached pic

 I deleted everything but my #+setupfile line and it still does that.

 Last bit of input -- when this behavior is displayed, if I C-c C-c on
 my options block at the top of the file, it returns to fontified
 behavior and stays that way (even if meddling with headlines). It
 appears that navigating to a headline with various #+keyword lines is
 not letting Org recognize something. Refreshing the setup seems to
 handles this. This is on:

 Org-mode version 8.0.3 (release_8.0.3-139-g419b69 @
 /home/jwhendy/.elisp/org.git/lisp/)

 Happy to try anything else or provide more info. For now, I think I've
 made enough noise about this!

 Without any #+ options at the top of the file, it appears in color.

End of last week, after updating Org, I also got lots of fontification
troubles inside Org buffers, but as well in more places (Gnus, in particular).

I restarted Emacs many, many times, used Org in different contexts, and
problems did always appear after some time (a couple of minutes, generally).

I did check out an older version of Org, and all the highlighting problems are
gone.

Currently used version: Org-mode version 8.0.3 (release_8.0.3-114-gab3f45 @
~/Public/Repositories/org-mode/lisp/).

I did not have time yet to bisect the problem, but it _seems_ to be a newly
introduced feature.

Maybe you can try to check out older versions ( 10 days ago), and see whether
you can replicate your problem?

Re: [O] TOC in HTML export - how to change formatting of ToDo levels?

2013-05-21 Thread Sebastien Vauban

Hi David,

David Rogoff wrote:
 I've just started diving back into org-mode. I'm mostly using it for ToDo /
 Status tracking. I've been trying to change the format of the TOC entries with
 little success. I've figured out how to use org-export-html-style to change
 the CSS markup for my customized ToDo levels, but that just affects the
 formatting in the body of the document. The table of contents appears to
 ignore that. I've been digging through org-html.el and the TOC formatting
 (around line 1474) looks to be mostly card-coded with almost no variables to
 control anything. Any ToDo status of done is not marked up at all and anything
 else is just marked as class todo instead of the actual class of the item.

 Am I missing something? The only solution I've found is to write a script to
 fix the HTML after exporting. Any better solution? It's a very big ToDo list
 and I (and others who will look at the document) want to see the actual status
 (preferably with the CSS font/text markups) in the TOC to know which items to
 look into for further details.

You should be able to customize the todo class only within the TOC context
with such a rule:

--8---cut here---start-8---
#table-of-contents .todo {
...
}
--8---cut here---end---8---

 This means I cannot put the above code in my init.el file where I

For such cases, I do write:

Typo: it's PGF, not PFG, just in case you wanted to google it or
something;).

Oops -- typo on my part.

I'd also mention Metapost, on which I believe TikZ was modeled (at least
to some extent).

Since you mentioned embedding in LaTeX, I'd also suggest TikZ; it has a
huge manual, but /very/ well written, with quite a few tutorials and
examples. One benefit is that it is tightly integrated into LaTeX,
but it can also export SVG (though with a few limitations compared to
the pdfLaTeX-produced output). Also, you might want to check out the
gallery of TikZ examples here: http://www.texample.net/tikz/ .

The examples are great. The link I provided goes right to the examples
vs. that sort of home page screen which only shows the most recent
couple that have been submitted.
