Yes, I think: compile + class + packages = process, if I don't joint
them to a profile setting, it is impossible to swith process easily.


If you know the default class and packages setting is suitable for your
process, just ignore :default-class :valid-classes :packages-alist
:default-packages-alist and :packages-override, the four options are
used by user special processes.

because latex system can deal with English very well by default, so you
can "don't care about the process", if I don't care about the process,
"the final document and its correctness" is just a dream. :-)

packages selected by org may conflict with user's latex package, so user
should edit `org-latex-default-packages-alist' by hand.

`org-export-define-derived-backend' seem to be overkill for this situation.

power users can do "anything" in org-mode, even rewrite ox-latex, my
question is that: is it flexible enough to let some power users to well
maintain some predefined configures which can make many beginning user's
install and config easily?

By the way, I don't like the #+latex_compile approach, In my opinion, it seem 
to be a
hack. For user, ox-latex provide too much configure options.

Maybe someone says, it is stupid duplicate code:

#+BEGIN_COMMENT
pdflatex-pdflatex-pdflatex
pdflatex-pdflatex-pdflatex
pdflatex-bibtex-pdflatex-pdflatex
xelatex-xelatex-pdflatex
xelatex-xelatex-pdflatex
xelatex-bibtex-xelatex-xelatex
luatex-luatex-lualatex
luatex-luatex-lualatex
luatex-bibtex-luatex-lualatex
#+END_COMMENT

but I think, it is a right approach, we must know, we have org contrib
package, and we have other personnel org extension package, we don't
need put all the process setting to ox-latex.el, we just add the
following three as defaults and examples.

#+BEGIN_COMMENT
pdflatex-pdflatex-pdflatex
pdflatex-pdflatex-pdflatex
pdflatex-bibtex-pdflatex-pdflatex
#+END_SRC

ox-latex-process:xelatex package can be provided in elpa or melpa,
if some need xelatex process setting, just install it.

Users can develop and share their own special processes with the
help of emacs package.

Similar, but include more information, maybe it it like:

#+BEGIN_SRC emacs-lisp
(setq org-latex-pdf-process-alist
  '(("pdflatex-pdflatex-pdflatex"
 :commands ("pdflatex -interaction nonstopmode -output-directory %o %f"
"pdflatex -interaction nonstopmode -output-directory %o %f"
"pdflatex -interaction nonstopmode -output-directory %o %f")

 ;; A string in `:valid-classes',
 ;; when nil, fallback to `org-latex-default-class'
 :default-class "article"
 
 ;; class-settings which works well with the process,
 ;; they must be defined `org-latex-classes'.
 ;; when nil, all class-settings defined `org-latex-classes'
 ;; are valid.
 :valid-classes ("article" "beamer" "report" "book")

 ;; the process's default packages, when nil
 ;; fallback to `org-latex-default-packages-alist'
 :default-packages-alist nil

 ;; the process's packages, when nil
 ;; fallback to `org-latex-packages-alist'
 :packages-alist nil
 :packages-override nil)))
#+END_SRC

>

It is different, 3 runs of latex as example:

if we don't deal with %latex place-hold in process commands,
#+latex_compiler is useless, we need to define pdf process
in org-latex-pdf-process-alist, 

   "pdflatex-pdflatex-pdflatex" "xelatex-xelatex-xelatex" 
"lualatex-lualatex-lualatex"
 
otherwise, we can use #+latex_compile and define pdf process

   "latex-latex-latex"

Reason:
1. Not so simple, we often need to edit `org-latex-classes'
   `org-latex-default-packages-alist' and `org-latex-package-alist'
   for many reason, for example: macro conflict

2. I don't want every users have to write latex-header in every org-file
and I like: install ox-latex-chinese and

   (setq org-latex-default-pdf-process "cn/xelatex-xelatex-xelatex")

every org-file can export to pdf.

Thank you for you help too :-)

The next work i want to do is:

1. org-latex-pdf-process -> org-latex-pdf-default-process
2. Add new variable org-latex-pdf-process-alist
3. Add #+LATEX_PDF_PROCESS setting


I am a member of emacs community in chinese, many org-mode latex
beginners will ask me: "How to export org to pdf by latex?",
this problem is annoying, so i deside to write a package:
ox-latex-chinese and tell them: "Install org-latex-chinese package!"

But, it is a diffcult work to convert my own org latex configure
to a well organized emacs package, setq nightmare!.

The above suggestion is a try to solve this problem.

Any suggestion? if you agree, i will code the patch.

`org-latex-preview-process' is a good idea, which make org-latex
beginner easily, i will add it.

I suggest to add (:generator my-generator-function) style configure
to `org-latex-pdf-process', it is simple and powerful feature, we
can use this feature to switch latex commands dynamicially, for example:

(defun my-latex-pdf-process-generator (texfile snippet extra-info)
  (cond
   (() ()
   (() ()

although we can set org-latex-pdf-process to a function to do the same work,
but this function is hard to write as org-latex-compile, it may only
useful for developer instead of user

caller-info argument is for the above feature.

Remove the above two and only use the below *one* ?

I have found the other problem, the below two version of
org-create-formula-image-with-dvipng generate different size png,
for they use different dpi.

I think, we should hold :scale to 1.0 and fix size problem in function

   adheres to org-contacts' method of structuring contacts and contact
   information. It not only supports the properties specified in
   org-contacts.el, but many other properties as well.

 * Basic support for vCard 4.0, 3.0 and 2.1.

   org-vcard is working towards full compliance with the vCard 4.0 (RFC
   6350), 3.0 (RFC 2426 and RFC 4770) and 2.1 specifications.

 * New contacts style: 'tree'.

Is it possible support this style?

Re: [O] To interrupt org-latex-pdf-process to regexp-replace some string of the .tex intermediate file and continue to export

[Feng Shu]

Leu Zhe lzhe...@gmail.com writes:

 I am using org-mode to write some article now. Org-mode is really a
 great tool to outline a article with great table and image support.

 Org-mode can display inline .png image but not .pdf file. Because now
 org-mode can not control the width or height of shown inline image, so
 i use matplotlib to produce low dpi .png image in PNG folder for
 inline display and higher dpi pdf image in PDF folder for finally
 article export.

 In .org file, the image link is like [[file:PNG\*.png]] and
 \includegraphics{PNG\*.png}in the produced .tex file. Then emacs will
 use org-latex-pdf-process to render it to pdf file. What I want is
 that before or in org-latex-pdf-process, a regexp replace function is
 added to replace the \includegraphics{PDF\*.pdf}, and then produce the
 final pdf file.

 Can anyone give a hand?

 Hello,

 I'm collaborating on a paper with some colleagues, and I convinced them

Maybe you can write a Makefile to change their emacs configure...

 My questions are:
 - is there a way to do this without an emacs-lisp block?
 - is there a nicer way to make sure that an emacs-lisp block is
 evaluated upon export than :exports results :results silent? (If
 I don't put it there, the block is not evaluated.)
 - is there a way to just say the name of the documentclass without all
 the boilerplate code below? In other words, can I say this is a llncs
 documentclass with the same sectioning as an article?

You should defun a classe for llncs.sty before use it. maybe
you can rename llncs.sty to article.sty, and put it to directory which contain
your org file.

 I sort of follow the below, but I think it would be more helpful to
 describe what you *don't* like about the output below. In other words,
 what are you trying to achieve that is not working below?


 It just suit my need, but I want to know more simper solution, which let
 me type less code.

 Hmmm. Not seeing a ton of ways to optimize, but it might depend on
 your total usage scenario. How many of these types of table/plot
 combinations are you creating? Just a couple sets, or a lot?

 The plot command is the only one that looks inefficient since a babel
 block with :file header would automate opening/closing a device... If
 you defined your data.frame in another babel block and used the
 :session argument, you could do something like this:
 #+name: plot
 #+header: :file /path/to/file.png :width 1600 :height 900 :res 200
 #+begin_src R :session r :exports results :results output graphics

 plot(data)

 #+end_src

 After that executes, you'll end up with a named results block which
 you can manually add the #+caption to? I typically use something like
 the above. Your solution is nice as one could add things like
 #+attr_latex or #+begin/end_center code via the paste() function in
 R... while mine saves having to manually do pnt(); plot(); dev.off().


 Another option might be to generate all your plots in a loop, perhaps,
 and then stick to just programmatically including them with Org
 syntax? I essentially did that here:
 - http://lists.gnu.org/archive/html/emacs-orgmode/2012-08/msg01167.html

 Not really much different than what your'e doing, though, I suppose.

 It would just scale nicely if you have various data sets and always
 generate a table and plot from them all. Then you could create your
 data.frames in a list and then lapply() through them with each of your
 functions, printing the proper Org syntax as the result (with :results
 drawer, as you're already using).

I use loop to generate multi tables.

There is a problem:  only the first table generated from current R src.
can be aligned correctly, which sometime is very annoy.

The below hook can align all the tables generate from R code:

#+begin_src elisp
(add-hook 'org-babel-after-execute-hook 'eh-org-babel-align-tables)

(defun eh-org-babel-align-tables (optional info)
  Align all tables in the result of the current source
  (interactive)
  (let ((location (org-babel-where-is-src-block-result nil info)))
(when location
  (save-excursion
(goto-char location)
(when (looking-at (concat org-babel-result-regexp .*$))
  (while ( (point) (progn (forward-line 1) (org-babel-result-end)))
(when (org-at-table-p)
  (toggle-truncate-lines 1)
  (org-table-align)
  (goto-char (org-table-end)))
(forward-line)))
#+end_src



 This thread also came to mind, as I was reusing lines like you are,
 and keeping them in separate babel blocks. I got the suggestion to
 call a named block, which might be of interest if you've not done that
 before?
 - General use: 
 https://www.mail-archive.com/emacs-orgmode@gnu.org/msg56684.html- Using a 
 #+call line:

 I don't think you can.

 You have to use it this way (not tested):

   (align-multi-table content)
 #+END_SRC
 #+begin_src R :results output raw drawer :post

 #+end_src

I prefer using a hook function to do this job, The below is my hook:

#+begin_src elisp

(defun eh-org-babel-align-tables (optional info)

Re: [O] Basic vcard-to-org-contacts converter

[Feng Shu]

Titus von der Malsburg malsb...@posteo.de writes:

 Hi list!

 I decided to give org-contacts a try.  Since there doesn't seem to be a
 facility for importing contacts in vcard format, I wrote a little Python
 script for that.  Perhaps someone on this list finds it useful.

   https://gist.github.com/tmalsburg/9747104

 The script uses the Python package vobject for parsing vcard files.  On
 Debian-like systems this package is available as python-vobject.  I
 tested the script with contacts exported from Apple's iCloud service and
 that worked well.  However, the vcard format is somewhat messy and I
 don't know what happens with vcard files generated in other contact
 managers.  Use at your own risk.

Import from csv is a solution too, I use the below hack functions to import a
csv file...

#+begin_src

(defun eh-org-contacts-parse-csv-line (line)
  Build a org contact from a csv line
  (let ((list (split-string line ,)))
(concat *  (nth 0 list) \n
:PROPERTIES:\n
:PHONE:  (nth 1 list) \n
:EMAIL:  (let ((string (nth 2 list)))
 (if (string-match-p @ string) string
   (if ( (length string) 0) (concat string 
@qq.com \n
:NOTE:   (mapconcat 'identity (nthcdr 3 list) ; ) \n
:END:\n)))

(defun eh-org-contacts-csv-import (optional filename)
  Convert a csv file to org contacts format and insert current point
  (interactive)
  (let ((file (if filename filename (read-file-name CSV file:)))
(buffer (current-buffer))
(point (point))
contacts-string)
  (with-temp-buffer
(insert-file-contents file)
(goto-char (point-min))
(while ( (point) (point-max))
  (setq contacts-string (concat contacts-string 
(eh-org-contacts-parse-csv-line (buffer-substring (point) (progn (end-of-line) 
(point \n))
  (forward-line 1)
  (beginning-of-line 1)))
  (switch-to-buffer buffer)
  (goto-char point)
  (insert contacts-string)))

#+end_src


 If there's interest, I might migrate the script to a proper Github
 repository and develop it further, i.e., merge your pull-requests ;-)

 way to get an html parse tree (libxml-parse-html-region start end),
 but I can't figure out how to convert that to the text I want. 

 Has anyone done anything like this?

Maybe eww can help you...

 The reason I wrote it in Python is that I don't know ELISP well

the below function  will only export name, phones and email

 So far, it is a one-direction approach and no synchronization
 solution.



 By the way: does somebody know of any somewhat intelligent tool that
 is able to compare two different VCard files? The main issue here is
 the fact that VCard order and property order within a single VCard
 can be different but the VCard file could still contain the same
 information. So line-by-line comparisons like diff do not work here.

This may be difficult, I use org-contacts and use a elisp function to
merge all the contacs which have  same name. then export contacts to a
vcard file.

 That should be possible with the existing VCard export.  See `org-contacts-

 Fair enough :-)

 However, I did additional things like checks, filtering, and so

 I have to admit that I don't know the feature-set of the Org-mode
 export. I would be very surprised, if the Org-mode export method is
 able to follow my custom photo: link I am using, grab the image
 file, test if it has a image format that works with VCard
 2.1 on Android, and encodes it in base64 accordingly.

 You see: I want to have ways to tweak the export process. And as
 long as I don't know ELISP that well, I stick to the tools I know.


 A side remark of mine: a couple of months ago I tried to find out
 how to store address information, phone numbers, and so on in
 org-contact properties. AFAIR I could not find anything except the
 :EMAIL: property. Is there a standard out there that answers
 questions like separate street from house number?, how to cope
 with multiple addresses for one contact?, and so forth? I created
 something on my own as you can see on [1].


 I am happy if you can get benefit from my little project and I am
 also happy when Org-mode offers a great export functionality for the
 rest of us :-)

Eric Schulte schulte.e...@gmail.com writes:

 Hi,

 I've been using ox-bibtex.el for a couple of days now and am really
 enjoying both the bibtex integration and the HTML export through
 bibtex2html.  I have run into one issue which I'm now sure how best to
 fix.

 When exporting multiple sequential citations e.g., cite:foo cite:bar
 etc... I would like to see something like the following (latex used for
 this example) \cite{foo, bar}, but instead I'm getting \cite{foo}
 \cite{bar}, which leads to poorly formed PDFs (a similar thing happens
 for HTML export).

May be you should use \cite{foo, bar} directly in org file.


 My question is how best to fix this, should I write a filter function,
 or does the export engine already have processes in place to handle
 these sorts of export context issues?

 Thanks,

 Hi,
 
 I don't have the developer skillz.
 
 Otherwise I'd be happy to help out any way I can, e.g. tracking issues

 patches on a more systematic basis.

 Thanks, this would be great.

 
 (The latter two assuming I can root out the setup/installation weirdness
 that seems to affect my local ODT export.)
 
 I see Jambunathan has placed his patches in the public domain under a
 GPL-compatible CC0 license. Other considerations aside, doesn't that
 mean they could be applied in Org?

 Putting them under CC0 means that we could use them, and that Emacs
 could in principle use them as well.  However, Emacs has made the *choice*
 to only include stuff for which they have the copyright assignment to
 the FSF.  (Stefan does reiterate this in the thread following Jambunathans
 message). Since Org is distributed as part of Emacs, this also applies
 to us.

 I have looked at the patches.

 1. Implement an alternative format for description lists.  Description
lists are, I think, already supported by the odt exporter, even
though odt does not seem to support them natively.
 2. As far as I can see, this mainly implements a simpler way to access
attributes internally.  It does not fix any bug I would know about.
 3. Introduces some kind of new way to force page breaks.  I don't
see why we need it.
 4. adds jabref support.  Sounds interesting, but I don't know if anyone
here uses it or would like to use it.

I use this feature now. In my opinion, this is very cool. 
I use org-mode to write paper draft and export the draft to odf file instead of 
pdf file, the 
reason is that I can't develop a suitable latex style 
for our university... so  ox-jabref.el + ox-odt.el become a 
easy approach.


 So I don't think any of this is required at this moment.  But it would
 be great if you could keep en eye out for mailing list requests and
 bug reports around this exporter and try to get things fixed when necessary.

 Thanks!

 Thanks for the requests.

 Numbering is done by ox-jabref.el and not by JabRef application, so
 these requests can indeed be met with 5-15 minute of effort.  But I
 hesitate to

 The main problem is there are just too many styles a Bibliographic
 Reference can be typeset - right from what some standard says, to what
 my university wants to what I prefer myself.

 This is where some sort of common agreement - even just among the
 members of the community - will help.  I will keep listening to the
 conversation and hopefully an opinion will emerge during the course of
 time.


We don't need include all the styles, but we should make the feature easy
hack for end users. we can introduce hook and filter!



  Forgot to mention:

  The speed of converting bib to xml is slow, may be we should introduce
  a cache system.

 If you use Numbered transcoders, then the citekeys are processed one
 by one.  So if there are 10 citekeys, then there will be 20 invocations
 of command line.

 One way of dealing with this is to choose a transcoder, that doesn't
 enumerate.  In that case the Bibliographic Reference is created enbloc.
 So the number of command line invocations will reduce to 11 = 10 + 1.
 The ASCII document that I circulated gives examples of such transcoders.

  just like previewing latex snippet.

 Caching of citekey-XML or whatever transformation is one option.
 Another option is to just disable citations for casual exports and
 enable it one for the final output.

 Something like

cite:t

 for #+OPTIONS.

 For now you can customize `org-odt-citation-transcoders' so that
 citation processing is disabled.

 I have wondered aloud in the past whether it is necessary to have two
 methods for this. They are pretty much equivalent although the
 imagemagick method is IMO slightly less brittle than the dvipng method.
 So instead of spending time to tie them even more closely together, we
 should investigate whether one of them should go.

 Maybe we can have a poll...
imagemagick method is useful for xelatex users, but it compile a snippet
more slower than dvipng method. 

We don't need remove one of them. we can do like this:

1. conbine tex:dvipng and tex:imagemagick to  tex:image
2. remove `org-latex-create-formula-image-program'
3. defcustom `org-create-formula-image-processes' in my patch.
4. update document.

It is very similar `org-latex-pdf-process'

[O] Please Comment: a potential Innovation about proviewing latex fragement with imagemagick

[feng shu]

* Approach of previewing latex fragement  with imagemagick is like this:
**  The original:

1. (emacs buffer font height) - (evalue a density value) -- (imagemagick
destiny option)
2. (latex fragement) -- (tmp latex file) - (pdf) - (png) ( convert with
above destiny option)

** Advantages
1. It works well at the moment.
** disadvantages
2. we get the formula about (font height - density value) by test and test
and test...


** A pontential approach:
1. (emacs buffer font height) - (latex macros;
\fontsize{font-size}{fontsize*1.2}) - (insert tmp latex file )- pdf -
png( convert with fixed density, for example: 96)

** Advantages
1. More intuition
2. This approach may be used  the feature p-with-dvipng, by using this
approach,
Maybe we can code a common function shared with imagemagick ang dvipng.

** disadvantages
1. depend latex command \fontsize.

 I understand that. Though, you didn't tell me what was wrong with the
 hook I provided.

 In my opinion, the solution seemd more hacky than mine for a user,  

 Of course. A hook (or a filter) is a hack. But at least, it doesn't live
 in core.

 It let my org-mode file more unportable.

 Portability is not an issue here. If you're really worried about it, you
 need to share your configuration file along with your Org documents
 anyway. If you don't, your documents will never be totally portable.

You are right, totally protable is impossible.  My goal is that my
document can work correct in standard org-mode environment, But it seemd
impossible in real world.  emacs = toss


 Could you share you opinion and reason about my approach:  Is the idea ,
 separating with  a new option, hacky?  or my code hacky? .

 My opinion is that we cannot add options to handle every possible use
 case. That's why filters and hooks exist in the first place. Thus, when
 a feature can be implemented in a couple of lines with a hook/filter,
 I just ask to think twice before adding it to core.

 Now, speaking about the patch, you only provide an option to ignore
 bibliography keyword when exporting with latex back-end, but you still
 have to write correct bibliography command by hand in the Org buffer.

filter can be used in babel? for example:

#+begin_src emacs-lisp
...
#+end_src


 I think a cleaner solution would be to be able to choose both
 bibliography and style according to back-end from within the keyword
 itself. I very much like Babel's by-backend approach.
I like Babel's by-backend approach too, but it may be  beyond my elisp 
ability... :-(

Before this patch, I tested below code, failed!
I like this approach, but it may be impossible  to realize.

#+BEGIN_HTML
#+BIBLIO
#+END_HTML



 That's more work for sure, but, meanwhile I think something like the
 hook I provided is good enough for the job at hand.

 What do you think?

 If you don't mind my chiming in, the standard way to customise Emacs
 behaviour (across all modes, not just Org) is through
 customize-variable.  Org cannot keep on introducing new keywords just
 because of convenience.

I don't think so, Convenience is very important in most situation. we can
introduce new keywords just for convenience!  #+LATEX_CLASS is a good example,
If we don't want convencience.  we can just customize `org-latex-default-class

The core is that how many org-mode users or potential users  
can benefit from this keyword!

we can export pdf with latex by using many different schemes and we can export 
pdf
with libreoffice. So adding a keyword which let users choose a pdf export 
scheme  
for current file is not a bad idea.


 In any case, this is also a security risk.  This starts an external
 process.  Allowing something like this means one can run an arbitrary
 command just by exporting a file.  I do not think that is wise at all.
 Exactly for this reason we have org-confirm-babel-evaluate defaulting to
 t.
If we only let user select scheme predefined in org-latex-pdf-process, I don't 
think security is a problem. If a user adding a dangerous command in 
'org-latex-pdf-process, he should know what he is doing. It's his choose.

 There is a big difference between the two variables.  Consider this:
 org-latex-classes depends per document (most likely you wand different
 documents for different things, hence maybe you also want different
 classes), however you want to choose your LaTeX backend once (at most it
 varies from project to project).  But again, if you use one build system
 for a project you are most likely using the same build system in other
 projects too.  The only difference I can see is when you have something
 like make for projects, but simply LaTeX for a simple document/notes.
 In that case, I would say Bastien's suggestion to use file local
 variables is best suited.  At one point I used something like this
 headline at the end of few Org files:

 * COMMENT local setup :ARCHIVE:

 # Local Variables:
 # org-latex-to-pdf-process: (xelatex -interaction nonstopmode
 -output-directory %o %f xelatex -interaction nonstopmode
 -output-directory %o %f xelatex -interaction nonstopmode
 -output-directory %o %f)

Powerful Tips, I like!  Maybe it should be include into org document. 


 Hope this helps,

 You need to use upper cases for keywords: @code{#+CAPTION}. Also,

   @code{#+CAPTION} keyword is the simplest way to set a caption for

 I agree that #+CAPTION isn't ready for complex caption commands (nor

 be documented in the manual (see 12.7.4 LaTeX specific attributes). In
 particular, documentation should insist on the fact that:

   1. :caption attribute has precedence over #+caption keyword
   2. :caption attribute is only meaningful special caption commands,
  i.e., this isn't the standard way to set a caption in Org.
   3. This is a raw command, nothing in it will be interpreted by Org.

 Here are some comments about the code:
  +  (caption-from-attr-latex (plist-get (org-export-read-attribute
 :attr_latex element) :caption)))

 You can use the following slightly shorter sexp:

   (caption-from-attr-latex (org-export-read-attribute :attr_latex element
 :caption))

  +(if (and caption-from-attr-latex (not (equal
 caption-from-attr-latex )))
  + (concat caption-from-attr-latex \n)
  +  (cond
  +   ((and (not main) (equal label-str )))
  +   ((not main) (concat label-str \n))

  +   (org-export-data main info)))
  +   ;; Standard caption format.
  +   (t (format \\caption{%s%s}\n label-str (org-export-data main
 info)))

 Here you can include the then part in the `cond', and use
 `org-string-nw-p':

   (cond ((org-string-nw-p caption-from-attr-latex)
  (concat caption-from-attr-latex \n))
 ((and (not main) (equal label-str )) )

 Hi Feng,

 In my thesie, I need add a caption to table or figure with
 \bicaption{中文标题}{English title}

 I assume you'd still want to use the #+CAPTION-cookie, no?  If so, one
 solution that comes to mind is writing captions like
 #+CAPTION:  my-Asian-string (sorry about my ignorance)  MYSPLIT  
 my-English-string

 and write a filter using (org-split-string text MYSPLIT) and format it
 as (format \bicaption{%s}{%s} LIST) if the length is two.  

 Org perhaps regexps could be used to identify 'my-Asian-string'.

 I'm not sure where to apply the filter, though, but a better solution
 than the one below would use `org-export-get-caption' on the correct
 elements at the correct time. . .

---
#+caption: 中文标题
#+caption: English Title
| 1 | 2  |

I think this is the best document construct, simple and  intuitive.

But, realizing this feature need some dirty hack, the main reason is
that \bicaption often a custom latex command, fig caption and table
caption are different in option, for example:

\bicaption[图]{...}[fig]{...}
\bicaption{图}{fig}{...}{...}
\bicaption{...}{...}

\bicaption[表]{...}[Table]{}

...


 Here's a dirty, inelegant regexp filter that's run on the final
 tex-string.
 #+begin_src emacs-lisp
 (defun org-latex-filter-split-caption (text backend info)
   When ## is present in a string make a bicaption.
   (when (org-export-derived-backend-p backend 'latex 'beamer)
 (replace-regexp-in-string caption{\\(.*?\\)[ \t]*##[ 
 \t]+?\\(.*\\)}
 bicaption{\\1}{\\2} text)
 ))

   (add-to-list 'org-export-filter-final-output-functions
'org-latex-filter-split-caption)
 #+end_src

It is a very useful tip, thanks!

 It will export this document 'correctly':
 #+begin_src org
 #+TITLE: my test doc
 #+CAPTION: -‡˜ ## english title

 #+CAPTION: english title

 Hope this inspires you to solve the problem in a more elegant manner.

CLASS and class-name are confusing,  I think LATEX_CLASS should rename

 Thanks for your patch.

 Though, it adds another keyword and another defcustom without providing
 any new functionality. I understand it is a shortcut, but the cons, IMO,
 outweigh the pros : adding a new class to `org-latex-classes' is a bit
 more tedious, but needs to be done only once.

 Therefore, unless you convince me this feature brings something new, or
 clearly eases a process, I'll stand on my ground.

Not all the org-mode users are expert of lisp and  not all of the org-mode
users are well in English, so finding the variable `org-latex-classes can
customize latex class and adding  a lisp block to it  may be not a easy
things for many users. 

So I expect org-mode can properly export latex without any configure,
but it is impossible for the complexity of tex system. So 

reusing exist `org-latex-classes items will become  a valuable thing, 
it should be implement. My patch is not best way to implement and it can 
be deny, but the problem can't be ignore. 

1. we can add a function `(defun org-latex-add-deriverd-class (class 
exist-class) ...)  to menupulate `org-latex-classes
2. My patch's approach.
3. others.

I think it is a way reusing the exist class defines in `org-latex-classes
If your class is similar with a exist one, 

For example:

#+begin_example

(article

 (\\section{%s} . \\section*{%s})
 (\\subsection{%s} . \\subsection*{%s})
 (\\subsubsection{%s} . \\subsubsection*{%s})
 (\\paragraph{%s} . \\paragraph*{%s})
 (\\subparagraph{%s} . \\subparagraph*{%s}))

(ctexart
 \\documentclass[11pt]{ctexart}
 (\\section{%s} . \\section*{%s})
 (\\subsection{%s} . \\subsection*{%s})
 (\\subsubsection{%s} . \\subsubsection*{%s})
 (\\paragraph{%s} . \\paragraph*{%s})
 (\\subparagraph{%s} . \\subparagraph*{%s}))

#+end_example

You don't need to add  ctexart to `org-latex-classes,

just type:

#+LATEX_CLASS: article
#+LATEX_CLASS_NAME: ctexart

 org-latex-fragment-templete-file

 Hello,

 I don't know other language users, for Chinese latex user, the first
 thing of write a document may  change the document class, for example,
 change article to ctexart. If I want use org-mode ,I should add all
 the class common used  to the org-latex-classes, It will be  a
 nightmare.

 In org-latex-class, article  and  ctexart elements are  very similar, the
 only different may be their class names.

 I want such result:

 1. I don't need customize 'org-latex-classes

 I don't see why customizing `org-latex-classes' _once_ would be
 a nightmare.

If all the CJKV org-mode users need customize this virable _once_ ,
It's a nightmare for org-mode, for all the CJKV org-mode users need to
know how to customize this virable!

If we add all the class common used in the world, `org-latex-classes
will be very very long!

 (eval-after-load 'ox-latex
   '(add-to-list 'org-latex-classes
   '(myclass \\documentclass{article}
 [NO-DEFAULT-PACKAGES]
 [NO-PACKAGES]
 [EXTRA]
 \\usepackage{mychinesestylefile}
   (\\section{%s} . \\section*{%s})
   (\\subsection{%s} . \\subsection*{%s})
   (\\subsubsection{%s} . \\subsubsection*{%s})
   (\\paragraph{%s} . \\paragraph*{%s})
   (\\subparagraph{%s} . \\subparagraph*{%s}

 And then in any given document:

 #+LaTeX_CLASS: myclass

At the moment, I am using the similar solution!  

If you use this way,  org-mode fragement previewing  may be broken if
you setting \pagestyle{fancy}. 



 If I need to layer another project-specific style file on top of that, I
 add a second line in the header:

 #+LaTeX_HEADER: \usepackage{someparticularpackage}

 Any document that might require Chinese starts as a myclass, and then
 goes from there. I set this up a year ago, and haven't needed to mess
 with it since.

There are many, the first one is ctex, which may be the most popular
latex solution of  chinese users.

All the university latex templates in China seem to be writen as
class, instead of style.

and nearly all  of them are derive from  class article or book

It is the reason that I want this feature:

#+LaTeX_CLASS: article:myclass

It will use default article template, and replace class name to myclass!


 Hope that helps,
 Eric
