How do you use org for other formats

How do you use org for other formats

[zwz]

Hi,

I recently found the problem when I want to export the org file to
html and pdf. I guess there will be some people (who are also not so
familiar with the powerful org-mode) bothered by the same issue, that
is, html and pdf requires different org format sometimes.
 - I use $ y = x_1^2 + x_2^2 $ in org, it works for pdf, but not for html
 - "_" in text will introduce mess in pdf, not in html

I definitely want to keep only one org which I can export to other
formats correctly. I do not know if it is already implemented in
org-mode.

I just wondered if it is possible to introduce a abstract level (or
notations) so that org can translate it according to the target
format, just like how org treat the headlines (*).

The following test file works fine for me as far as I can tell

Hi all,

I don't export from org at all, but Bernt's pdf doesn't look right to 
me. Notice that in the first equation, the exponents appear as `^2' 
(i.e., with the `^' character). As a heavy LaTeX user, I would write 
it as `y = x_{1}^{2} + x_{2}^{2}', but trying Bernt's file with this 
modification, I still had the same result (`^2' in the output as 
opposed to a superscripted `2'). Org 6.28d and emacs 22.2.1 on ubuntu 
8.10.

Best,

Brian vdB

Well, not quite: the subscripts in HTML are too big  and the first formula in
the PDF does not have superscripts (it still has the carets): I checked LaTeX
export and the problem is present there:

  y = x$_1$\^{}2 + x$_2$\^{}2

  y$^2$ = 2x$^2$ + 1

  z$_2$ = x$_1$ + x$_2$ + 2 (y$_1$ + y$_2$ + r)

PS. The exponent in the last formula (i.e. the 4) is absent from the org
    file: cut-n-paste problem?

Actually you're right - I didn't notice that.  If I export via docbook
(C-c C-e V) it looks better:  http://www.norang.ca/tmp/x-3.pdf

Bah.  I added the ^4 after I'd already included it in the email :-P.
Sorry.

  Some math formulae:

  y = x_1^2 + x_2^2

  y^2 = 2x^2 + 1

  z_2 = x_1 + x_2 + 2 (y_1 + y_2 + r)^4

Yes, it does look much better (does it work as well with HTML?). So there
is a bug in the LaTeX exporter apparently. However, I tried the LaTeX
fragments approach in section 11.3 of the manual and it works fine with
both LaTeX and HTML (but you have to turn the LaTeX option on: exporting
to HTML then preprocesses the LaTeX fragments to produce images that can
then be included in the HTML file):

I've never tried that.  My DocBook toolchain seems to be a bit broken
ATM since installing nxhtml mode.  I just used the standard PDF via
Docbook export in org-mode to generate that file.  I've never tried
DocBook to HTML (or any other format).  I'd really like to get to a
point where everything goes through a standard DocBook toolchain since
it supports more output formats.

As long as the PDF generated from DocBook output is good, the HTML
format should be good too.

Here is the HTML output converted from DocBook XML file (the command I
used is ``xsltproc /Users/bcui/Downloads/docbook-xsl-ns/xhtml/chunk.xsl
t.xml'', where t.xml is the DocBook exporting result):

Wow, so many options I have not used before ...

I copied the text, but the exported HTML and PDF looks the same as the
formula in ORG. Then I found it was because in my .emacs, there is

(setq org-export-with-sub-superscripts nil)

After I comment this, it works.

But in this way, I have to pay special attention to sub- and super-
scripts.

The #+OPTIONS: line with ^:t or ^:nil controls whether _ and ^ create
subscripts and superscripts.  I set this per org file to control that
option for export.

Please note that the non-LaTeX processing is only good for really  
trivial
math in Org.  The LaTeX exporter has a really hard job handling
a variable with both a sub and a superscript, because it needs to insert
the dollar signs to create math mode without messing up with the number
of dollars.  Actually, it is a small wonder that it works as well as  
it does,
Bastien did a amazing job when he wrote the LaTeX exporter.  The HTML
exporter does not have this specific problem, so it handles x_1^2 OK,
but anything more complex will fail as well.

If you want to typeset a document with math beyond a single subscript
or exponent, the much better way is to actually enclose it in LaTeX
math delimiters.  For LaTeX export this will work perfectly.  For
HTML export you need to follow Nick's advice in this thread to turn
on LaTeX fragment processing with

#+OPTIONS: LaTeX:t

When you have installed dvipng, HTML files will then include the math
formulas as small images.

I think this is probably fixable with CSS, decreasing the font size
in sub and sup.   Apparently Docbook does this automatically for
its subscript and superscript tags.

Should we decrease the size of sub and sup in Org's default CSS?
