Sorry, the problem is the output of literal OrgMode formatting
characters in LaTeX which could be misinterpreted for PDF generation.

I get links in my PDF labeled:

- literal output "/Org-Mode/" and "=Org-Mode="
- miinterpreted "rg-Mode"

The formatting in URLs labels is managed for HTML, I was
expecting something like the following for LaTeX:

#+begin_src latex
\href{http://orgmode.org}{\emph{Org-Mode}}

\href{http://orgmode.org}{\verb=Org-Mode=}

\href{http://orgmode.org}{\underline{Org-Mode}}
#+end_src

Or at least, stripping the formatting characters to prevent clash with
LaTeX processing.

Regards.

It is a bad idea(TM) to track both the sources and the result of a
generation from that source in the same repo.  That other projects are
doing that doesn't mean we should follow their example.

It may not be a problem for you.  It probably isn't for me.  I'm still
not saying it won't be a problem for every org-mode user.  You need to
think about possible problems from the user perspective.

Please have a look at Nicolas' code first before making such statements.
I haven't seen ragel output, especially not in ELisp and I don't know
how easy it will be to debug parse errors.  The other thing to keep in
mind is that org-mode doesn't have a formal syntax description, much
less one that follows one of the standard grammars.  This will be a much
bigger fish to fry then

I haven't checked.  But all this happens in machine code, not ELisp, so
it is not clear on whether a re-implementation of the regex engine, even
if it is vastly superior to the one Emacs uses now would be a net win.

That trait is shared by all regex engines that allow backreferences.

One problem - when using bash as the shell, when trying to execute the compiled 
file, it tries to execute the empty file, not the file that was just compiled 
(which has the same name, but the extension .exe, added by the compiler). 

A partial solution to this is to append ".exe" to the name of the binary temp 
file if running under Windows. E.g., start org-babel-C-execute something like 
this:

(defun org-babel-C-execute (body params)
  "This function should only be called by `org-babel-execute:C'
or `org-babel-execute:C++'."
  (let* ((tmp-src-file (org-babel-temp-file
"C-src-"
(cond
 ((equal org-babel-c-variant 'c) ".c")
 ((equal org-babel-c-variant 'cpp) ".cpp"
 (tmp-bin-file (org-babel-temp-file 
"C-bin-"
(if (equal system-type 'windows-nt) ".exe" "")))

[...]

I say "partial solution" because the output in the org file is *still* blank, 
but at least the program does get run this way...

One question - why create a temp file for the executable before running the 
compilation? Why not just have it created by the compiler?

I have been experimenting with parsing the format-string to build a
regexp to match the generated-strings.  This approach depends upon the
parsability of the expansions of each of the percent-codes.  As concerns
org-log-note-headings, %t, %T, %d, %D, %s, %S, and %u all have parseable
expansions, as far as I can tell.  I'm not sure about %U, but if the
rest of the string is not too complicated, it shouldn't be a problem.
Format-code flag, width, and precision add some complexity to the
problem of generating regexps to match the codes, and I haven't done
that bit yet.  Overall I think this could be a very viable approach, and
I'll paste my scraps of code below:

;;; parsing state changes
;;;
(defun org-split-format-string (str)
  (let ((case-fold-search t)
(format-regexp "%[+ #-0]*[0-9]*\\(\\.[0-9]+\\)?[%a-z]")
(parts (list))
(s 0))
(while (string-match format-regexp str s)
  (let* ((beg (match-beginning 0))
 (end (match-end 0))
 (before (substring str s beg)))
(unless (string= before "")
  (push before parts))
(push (substring str beg end) parts)
(setq s end)))
(let ((last (substring str s)))
  (unless (string= last "")
(push last parts)))
(nreverse parts)))

I reverted David's change and replaced `delete-backward-char'
by `backward-delete-char', which isn't caught by the compiler*.

`backward-delete-char' is remapped to `delete-backward-char' 
by Emacs and `delete-backward-char' is remapped by Org to
`org-delete-backward-char'.

Thanks for your patience on this one!

* This looks weird that an alias isn't caught by the compiler,

This looks clever, but is it safe?  E.g. if cells of the table are
surrounded by double-quotes, you'll have the same number of quotes in
each row, but the double-quote char by itself is _not_ the separator.

So I'm not sure about this heuristics -- want to ear/test more.

That an easier way and I would favor it: keep the current behavior, 
but add an option for a list of separators that the user can set.  
Org would then test this list sequentially.  

What do you think?

Agreed.  

Is anyone volunteering for listing the items in such a menu for Babel?

If so, I'm willing to implement this.  

I'm not convince we should have a menu item to (de)activate each
language though -- more a menu that exposes the basics.

Writing an Org parser with Ragel looks like an interesting project in
itself, theoretically speaking -- and you will find great minds around
that will follow and support your progress on this.

But for a GSoC project, we have to think in very practical terms ("how
will this improve the current code-base?)  Achim's remarks are good
ones.  And remember potential mentors are volunteers, the same ones 
that (try to) maintain Org everyday.

Anyway, I'm glad to learn about Ragel.  But as I said, my priority 
goes to anything that can help Nicolas parser (testing, learning, 
adding new backends, etc.)

Can you post your patch to the list, along with a commit message as

It's not clear to me if you are talking about manually inserted LaTeX
labels within an Org file or if you mean LaTeX labels that will be
inserted in the .tex file as exported from an Org file.

Can you be more precise here?  Maybe send an example?  I'm pretty sure

Not really.

But adding commas for the rare occasions where C-c C-c on a src block
will insert "*" at the beginning of lines will triggers questions from
users who don't read the manual (there are a few.)

Since you only need to export your preamble in HTML once, I'd rather use
`org-export-html-preamble' and set it to the HTML string you want.

There may be other ways using #+INCLUDE but the solution above is the
one I use.

It seems that the problem is with the ASCII export, the backslash to
escape the underscore is not striped.

Ragel is written in C++ and has no dependency.

* every major platform has a C++ compiler
* ragel input along with generated code can be tracked in the repo
* the generated code is portable since it's elisp (doesn't need to be
regenerated on different platforms)
* the parser is a confined part of org-mode

I don't think this is a problem.

I think the fix will be shorter and simpler in the syntax because it's
easier to reason on an abstract definition when it comes to language.
When you're neck-deep in your handwritten implementation trying to
figure what you did wrong, it can take a long time.

I haven't tested anything yet.
If I remember correctly, the emacs regex API doesn't provide a way to
compile patterns and thus have to be compiled at each call.
Also the underlying FSM implementation uses NFA which can lead to a
exponential complexity in time [1] for certain patterns.

That works as a workaround, as long as I remember to do it.  Is there a reason
not to automatically do this to the return value of doing "C-c C-c" on all
"#begin_src R" blocks?

Also, what if I need real commas in my literal stuff?  Any way to escape those?
 Just add one more comma, maybe?

[O] [PATCH] Support hour in repeated task cookie

[Takafumi Arakaki]

Hi,

Basically, this patch changes all occurrence of "[dwmy]" with
"[hdwmy]" and adds "("h" . hour)" to whata of org-auto-repeat-maybe.

I think it is better to have some constant to indicate "dwmy".  So,
this pull request is rather a proof-of-concept and a feature request.
I didn't try to do it by myself because I thought org developers might
have some preference to how to add this constant.  If somebody who can
commit the change can add a constant and introduce "h" for repeated
cookie, please do it.  If you think I should create another patch to
add the constant, please give me a name of the constant.   How should
we call "dwmy"?  "Time unit chars" or something like that?  If the
current patch is acceptable, it is fine for me.  Maybe you want to introduce
some constants afterward.

Best,
Takafumi

It needs yet another tool to fully build org-mode from scratch, which
needs to be installed, bug-free and configured correctly.  Right now all
one really needs to have to build org-mode is a working Emacs (even make

No, you can (for a suitably restricted set of languages) formally proof
that the implementation and the specification is identical for any
input.

The assumption that an FSM running in ELisp is faster than a bunch of

[O] Export of link with underscore does not work nicely

[Daniel Dehennin]

Hello,

I try to export the following as HTML and text but the output is not
optimal:

#+begin_src org
This is the
[[http://www.postgresql.org/docs/9.1/static/client-authentication.html][pg_hba.conf]]
configuration file
#+end_src

With HTML export, the "hba" is subscript.

Escaping it with a backslash works fine for HTML export but not for
ASCII one.

Is this intended or a bug?

Regards.

Re: [O] Problems running C code in org-mode under Windows

[Richard Stanton]

I think the "Access is denied" problem is probably the same as that listed here:

http://lists.gnu.org/archive/html/help-gnu-emacs/2010-04/msg00247.html

Unfortunately, when I switch to using bash as my shell under Windows, this 
causes problems with python-mode (though this is not really your problem...) 
This change does get the compilation to work on my machine, however, and a .exe 
file is created. So far so good...

However, the output still appears blank in the org buffer. More tracing 
required...

I'm discovering org-mode little by little. The whole org-babel thing
is really nice too. So what you want is an org-babel interface that
will convert a source block input for ragel to an image of the
automata/generated code once you export e.g. to html?

You mean it complicates the build process? I'm not sure I understand.

Well I've never done it for big language but I did not find it that
easy. Mistakes are easily made e.g. you end up accepting more thing
that the language does in order to simplify the code, etc.

I'm not familiar with this. Does this mean you test random valid and
invalid input against the parser (aka fuzzing)?

I'm not very experienced (just a student :) but for me their
usefulness is in the robustness and the abstraction it brings. It also
happens to be faster. But I see what you're saying.

[O] table not returned

[Andreas Leha]

Hi all,

I have problems with the following table to be inserted into the org
mode buffer:

#+begin_src R :results table
  data.frame(parameter=c("parameter", "", "param1"),
 mean=c("mean ± sd", "", "1.1 ± 0.1"),
 median=c("median", "(minimum;maximum)", "1 (1;2)"))
#+end_src

#+results:

The problem seems to be the "(" as a first character in a cell.  Is
this a to-be-expected limitation of org-mode tables?

Andreas

Using a parser generator can be flexible too. Big changes in the
syntax usually implies big changes in the parsing code. With a tool
like ragel the operation is much less painful since the code is
generated. Also, if the org syntax can be written as a grammar, it can
be safely imported in other software that have a parser for it making
the format more portable.

Frankly, I don't know ragel very much either. I've only used it on
very simple things. But it's easy to use. You can even execute action
at any state while parsing a token (look closely at the example on the
homepage).

Yes, the output of the parser has to remain the same otherwise I would
have to rewrite everything :p

[O] table column with trailing 0s

[Andreas Leha]

Hi all,

I am trying to get a table generated from R to be pretty printed in
org mode (and the export).

Suppose, I have a table like this (typical statistical table):

#+attr_latex: align=lr
#+begin_src R :colnames yes :exports results
  data.frame(parameter=c("param1", "param2", "param3", "param4"),
 pvalue=c("0.80", "0.15", "*0.03*", "*< 0.01*"))
#+end_src

#+results:
| parameter | pvalue   |
|---+--|
| param1| 0.8  |
| param2| 0.15 |
| param3| *0.03*   |
| param4| *< 0.01* |

Here, org mode strips the trailing 0 from param1 which makes the
table a lot less readable.

How can I tell org not to trim the contents of string(!) columns?

Regards,
Andreas

There is still one thing, that we can do: call org-notify-process
periodically, but only when the user is idle for at least some seconds.
This logic exists already in gnus-demon-add-handler but the gnus-demon
runs only when gnus is running. So, what we can do is:
- patch gnus-demon.el to allow running the daemon independently of gnus
- copy parts of gnus-demon.el
- perhaps something else...

Some day I'll take a look.

Thanks for tracking down the source of this problem.  Unfortunately this
is beyond my abilities to address.  It would be interesting to hear if
others on this list are having issues compiling C code blocks on
windows.  To the extent that this appears to be a problem with the Emacs
`call-process' and the cmdproxy executable maybe a bug report to Emacs
would be appropriate.

Re: [O] Problems running C code in org-mode under Windows

[Richard Stanton]

I've been tracing through, and a problem occurs when the compilation gets run, 
which is at about line 155 in file ob-eval.el, inside function 
org-babel-shell-command-on-region, where call-process region is called.

As far as I can see, at this point the command being called is

C:/emacs/emacs-24.0.94/bin/cmdproxy -c "gcc -o 
\"c:/users/stanton[...]C-bin-10700opx\" 
\"c:/users/Stanton[...]C-src-10700bfr.c\""

(where [...] just means I deleted some more path information, but it's all 
valid).

If I execute this exact command at the command line, the compilation works 
fine, and creates an executable file C-bin-10700opx.exe (note that gcc on 
Windows automatically adds the .exe extension if you omit it). However, after 
running the call-process-region command in the .el file, no executable file is 
produced, and error-file has the contents

Access is denied

Not sure why this should be, but the compilation is not happening.

If you'd rather set this up as a web service (instead e.g., an email
front-end as mentioned in another reply) one intermediate step would be
to write a tool for conversion between json (or some other web-friendly
data type) and the Org-mode list representation defined in
org-element.el in the contrib directory.

Such a task should be fairly straightforward (in fact there may already
be elisp<->json conversion tools written), and once done would allow for
easy generation of Org-mode files from structured data.

To me this does seem like it could be useful.

Assume a workgroup of people - they use emacs / orgmode.  Mostly Linux and OS X,
but there might be a weirdo or two still using Solaris.

They get TODOs from people who do -not- use emacs: managers, project managers,
Windows users, end users ... like that.

The input arrives (mostly) via email.  'Attend Meeting Foo at 08:00 p.m.' 'Fix
Bug umptyfratz this week'.

orgmode user manually inputs this data into emacs.



I had a few free minutes and thought 'there must be a better way': 20 minutes a
day to organize tasks * Y people on a team = a lot of wasted hours.


Is there a programatic method already coded up to take bits delivered to a

[O] Document Freedom Day tomorrow

[Bastien]

Dear all,

tomorrow is the "Document Freedom Day": 

  http://documentfreedom.org

I will be online and connected to the IRC channel #org-mode
from 9:30am to 6:30pm (Paris time), with a break at lunch.

Is anyone interested in participating to the improvement of
Org's documentation during the day?

Here is a suggested list of tasks:

- org.texi enhancement: fix typos, spelling mistakes and other
  problems with the main documentation file org.texi.

- Worg tutorials: write tutorials that are currently missing:
  http://orgmode.org/worg/org-tutorials/index.html#sec-7

- Org screencasts: select a list of useful screencast to have
  and review/publish them.

- Org/Worg documentation translations: translate tutorials and
  main documentation (org.texi, orgcard.tex, etc).

If you can spend some time on #org-mode to participate to this
that'd be great!

Thanks,

I had the same problem on ubuntu. What I did was:

- I get org-mode from git and install it in my ~/emacs/org-mode directory. 

$ cd ~/src/org-mode
$ make SHELL=/bin/bash prefix=/home/aitor/emacs/org-mode
$ make SHELL=/bin/bash prefix=/home/aitor/emacs/org-mode install

- In my .emacs, I have this:

(defun remove-org-dirs (dirs)
  "remove all list elements containing the matching '/org$'"
(let ((result))
  (dolist (dir dirs)
(unless (string-match "org\\'" dir)
  (setq result (cons dir result
  (nreverse result)))

(setq load-path (cons "~/emacs/org-mode/share/emacs/site-lisp"
  (cons "~/emacs/org-contrib/lisp"
(remove-org-dirs load-path

The "remove-org-dirs" function removes any system directory for "org"
and thus makes sure that my copy of org-mode gets loaded.

Hope this helps,

[O] [BUG] [babel] result wrapping with indented source blocks

[Andreas Leha]

Hi all,

there seems to be another bug related to indented babel source
blocks when the results are wrapped.

Here is an example.  Try to evaluate this block twice.  (Keeping the
indentation)

,
|   #+begin_src sh :results file wrap
| echo "test.txt"
|   #+end_src
| 
|   #+results:
|   :RESULTS:
|   [[file:test.txt]]
| :END:
`

The second evaluation fails with the error
#+begin_quote
progn: Search failed: #("^  :END:" 1 3 (face org-special-keyword fontified t))
#+end_quote

Regards,
Andreas

[O] org-mime-htmlize: visual representation (thunderbird)

[Uwe Brauer]

Hello

Now that the bug in org-mime-htmlize is fixed, I would like
to comment on the visual representation. Most likely this
has to do with the mml package.

When I write the following message 
Integral


$$\int fdx=0$$
And


\begin{equation} 
\sum_{\alpha} 
\end{equation}

and apply org-preview-latex-fragment and then
org-mime-htmlize and send this message to gmail. 
The 'gmail-reader' displays them fine.

However thunderbird does not and I apply the resulting eml 
file below (I presume a screenshot is not appropriated)

Now tunderbird itself has an extension (latex-it) which does
something similar to org-mime-htmlize, it sends latex math
as png. However there are "better* displayed, I attach the
relevant eml file below.

Could org-mime-htmlize use the structure of latex-it?

Thanks 

Uwe Brauer

So there are quite a lot of possibilities.

I think I have to figure out a standard set of keybindings/window-moves
and set them in all my 3 window managers (tmux, stumpwm, and emacs
itself) in a similar way (only with different prefix), otherwise it will
drive me nuts to do the same thing in so many different ways. I will try
Bastiens library first, since it looks quite impressive.

Thanks for the tips.

M- is somehow used by Archlinux itself it seems, they change

Wow, almost 1000 lines and more than 50 defuns ... a real hidden gem, it
seems. I will try it out, it is probably much more than what I was
looking for in terms of functionality, but maybe I can figure out a core
set of functions that work consistently in most situations
(console, X11, orgmode ...).

Thanks a lot!

the current exporters don't allow this, but the new export engine

The plan is to merge the new export engine into Org's core before
version 8.0, so please stay tuned.

[O] Create preamble from an .org file ?

[Vincent Beffara]

Hi,

To manage my personal website I would like to use the publish function 
of org-mode. For the contents of pages, there is no problem, and the 
auto-sitemap feature is promising. however, I would like to have some 
common contents to all the individual pages, and they would best fit in 
the preamble part. Essentially, I would have a preamble.org file 
containing this:



#+IMPORT: sitemap.org

* A few links
  - link 1
  - link 2

* Contact info
  - address
  - email


and the contents of the preamble would be an html version of that (of 
course without all the  section and so on). Optimally, of course, 
preamble.org should not be linked from the site map.


How do I do that? Maybe a dedicated .org file for the navigation bar is 
not the right way to do, is there a better one?


Thanks,

/vincent

[O] [PATCH] link descriptions in :file results of src blocks

[Andreas Leha]

Hi all,

this small patch adds :filelinkdescr to the list of possible header
arguments for babel source blocks.
Its intented functionality is to allow source blocks to return links to
files with description.

Two small examples:

,[ example1 ]
| #+begin_src R :results graphics :file test.png :filelinkdescr here
|   plot(1:10)
| #+end_src
| 
| #+results:
| [[file:test.png][here]]
`

,[ example2 ]
| #+begin_src R :results graphics :file test2.png :filelinkdescr
|   plot(1:10)
| #+end_src
| 
| #+results:
| [[file:test2.png][test2.png]]
`

If used with value ("here" in the example1) that value will become the
description.  If used without value (as in example2), the description is
taken from either the :file header argument or the results of the code block
evaluation (in that order).

Have not done much testing yet, though.

Regards,
Andreas

There is window-numbering-mode which grabs the ALT+num key
combos in order to switch to numbered windows.  I now am used to
^U-NUM to enter numerical arguments but its strange at first.

Then there is switch-window which captures the ^X-o key binding,
displays a number in each window and you are required to press
the correct number in order to switch to its window.  While the
numbers are shown one does not see the contents of the windows
any more which is a bit distracting.

Both work at the console.

Re: [O] link to pdf in latex export

On second thought, not a very good solution. It only solves your 
problem if you always want to link to a certain file type (here PDFs) 
and not sometimes inline it as a graphic.


I usually just fix this manually, by evaluating the source once, 
removing the #+RESULT line and adding a description part to the 
resulting link so it is exported as a link hereafter.

You might want to try windresize:

I hacked this quite a while ago because windmove.el didn't fit
