Re: [O] [PATCH] Separate clocksum format for durations = 1 day
Toby Cubitt ts...@cantab.net writes: Here's an updated patch. Now both org-time-clocksum-format and org-time-clocksum-fractional-format can be plists, as discussed. That was quick. Thank you. In the org-time-clocksum-format case, I made the values cons cells which specify both a format string and a boolean. The latter indicates whether the time component should always be included in the formatted duration, even if its value is 0. This is needed for the hours component to reproduce the current default format, and I figured I might as well make it general. I understand. It is a necessary evil. Though, instead of asking for cons cells, maybe the boolean could be provided as another property. I.e. '(:hour ... :persistent-hour t) would be a replacement for: '(:hour (... . t)) And, better, '(:hour ...) would the become a replacement for '(:hour (... . nil)) What do you think about it? The name of the property is only a suggestion. I used a somewhat complex customization type in the defcustoms, instead of a straight plist, in order to produce a better ui for the customization interface.

Re: [O] subtree-export limitations
Ok, thanks to both of you. I'll stick with the workarounds pointed out by Alan for now. Anyway, I'm still curious if it wouldn't be feasible to treat subtree-options more similar to inbuffer-options?

The responsible function is org-export--get-subtree-options, which builds a list of already seen keywords. The lists members are then ignored if seen again. Is there any particular reason why this is done? Since Alan gave you a workaround, I will try to answer the why. I believe the reason behind this behaviour is properties are not designed to accumulate values. I believe there is a special case treatment for certain babel uses; as I'm hazy on the details, you have to look in the archives from about a year back (my memory tells me September 2011 to December 2011). You should look for discussions involving Rainer(?) and Eric Schulte. Hope this helps.

Using the new exporter, something like should replace any table using

automatically.
I didn't manage to get your (Nicolas') or my own attempt working
correctly for exporting matrices. I still think it would be nice.
I tried to use the regexp
(not (string-match |[\\+-]+| table))
to identify tables without heading separators, but it didn't work
properly.
Thinking about it, it might be nice to be able to specify table export
function more generally. For instance, I might have a matrix with
labels (in LaTeX a bordermatrix or kbordermatrix). Likewise, it might
also be nice to specify a header argument to tables s.t. I can specify
a name, e.g.
#+NAME: P
#+TBLOPTIONS: :prefix P= :type matrix

It's hard to fix this since you're not very explicit here.
I tried to use the regexp

It cannot work in filters. These are applied on back-end ouput, in this

Thinking about it, it might be nice to be able to specify table export

labels (in LaTeX a bordermatrix or kbordermatrix). Likewise, it might
also be nice to specify a header argument to tables s.t. I can specify
a name, e.g.
#+NAME: P
#+TBLOPTIONS: :prefix P= :type matrix
| a| b|
| c| d|
would export to
\[P=\begin{bmatrix}ab\\cd\end{bmatrix}\]
There is no TBLOPTIONS affiliated keyword, but it could go in ATTR_LATEX
since this probably only makes sense in a LaTeX-type output. If you
provide a full description of options and their effect, I might try to
implement it.

Re: [O] Beamer frame with an empty title ?
Would a non-breaking space as the title work?
Nope, because, the space for the title would still be there and I want to
put a full frame image

But this one will work and is esay enough. Thanks.

If such need is common enough, we may provide a special environment,
much like againframe, which would provide a frame without title. For
example:
* Headline

I don't fully understand this thread but to get a full frame photo on a

Re: [O] Export tables as matrices (change tbl-export function on the fly)
Nicolas Goaziou n.goaz...@gmail.com writes:
I didn't manage to get your (Nicolas') or my own attempt working
correctly for exporting matrices. I still think it would be nice.
It's hard to fix this since you're not very explicit here.
Sorry; you posted a code first which didn't work at all for me; I
tried to fix it, and I posted a code which I though worked but in the
end it didn't. Thus, I though it would be fair to post another
message stating this, if nothing else than for future viewers.
I tried to use the regexp
(not (string-match |[\\+-]+| table))
to identify tables without heading separators, but it didn't work
properly.
It cannot work in filters. These are applied on back-end ouput, in
this case LaTeX code, not on Org code.
Aha, that explains a lot. At some point when I don't have so many
assignments I really need to get to know the details of your work.
It's has so many cool features.
There is no TBLOPTIONS affiliated keyword, but it could go in
ATTR_LATEX
That a lot more clever. I just made up TBLOPTIONS since I couldn't
think of anywhere better. But you are of right. Such an option would
fit perfectly into ATTR_LATEX.
If you provide a full description of options and their effect, I
might try to implement it.
Okay I'll try. I don't know whether something like the below is what
you are thinking of. I use matrices all of the time so it would be
nice for me.
- PROPOSAL: New option(s)for ATTR_LATEX
- :type :: options a lisp translation function or key words
associated with a lisp list translation function.
- Default keyword: table; other known keywords: matrix
- table: current exporter
- matrix: exports to LaTeX matrix determined by the variable
org-export-latex-tables-matrix-default-type or :matrix-type.
Default is: bmatrix or pmatrix (probably bmatrix).
- in general array requires more configuration, but for me
array need not be supported.
- Matrix relevant keywords :: are the following
- If the additional variable ALIGN is set to k ∈ {l,r,c} use
the starred version of
org-export-latex-tables-matrix-default-type or :matrix-type
- If the additional keyword :bordered is t use the typeset
the matrix as \borderedmatrix{col1
... colN\\row1...\\...\\rowN}. A better example is
here ¹. Also, the default bordermatrix macro is determined
via org-export-latex-tables-matrix-bordered-type s.t. one
can specify kbordermatrix ² or qbordermatrix ³. Perhaps
Org automatically add the respective usepackage if this
option is set to something different from bordermatrix
(i.e. org-export-latex-tables-matrix-bordered-type is a
list of lists where the first element of a list is the
macro name and the second is the needed package).
- If :matrix-pre string is set string is typeset before
the matrix
- If :matrix-post string is set then string is typeset
after the matrix.
- Alternatively, CAPTION could be used, but it seems weird.
Are they written before or after the matrix? I'd prefer
CAPTIONs to be ignored typeset when matrices are typeset.
- If the table has a name the matrix is typeset using
equation and given an label. If not it may be typeset
using equation* or \[·\].
- Potentially: an :inline exists s.t. if inline is t the
matrix is typeset inline [i.e. with \(\)]. Perhaps, it
should be smart and use the small verison of
org-export-latex-tables-matrix-default-type. I.e. if
bmatrix use bsmallmatrix. This could be set via
org-export-latex-tables-matrix-inline-small.

Agreed. Perhaps a new property, OPTIONAL_TITLE? The texinfo back-end

sectioning command, e.g., \chapter[optional]{title} (if this isn't
already possible).
On the other hand, wouldn't it

I don't think so. We want either sentence case (Properties and columns)
or title case (Properties and Columns), not capitalized (Properties And
Columns).

I had overlooked the fact that you wanted the property to be effective
across back-ends. So, it would define how the entry should appear in the
table of contents in every back-end where it makes sense.
That's a bit of work, because, so far, node-property values are not
parsed. So it would require to define a new class of node-properties:
those with a parsed value. But then, how to decide which properties have
their value parsed are parsed and which have not?

Re: [O] Bug? R: Org babel block execution *drastically* slower than in ESS session directly
2012ko azaroak 16an, Eric Schulte-ek idatzi zuen: The attached patch adds a really-silent results header argument. To see the impact compare the running time of the following two code blocks. Unfortunately, the attached patch doesn’t work correctly. This can be seen by replacing the “seq” command in your examples with a command that has side effects – notify-send, aplay, etc. In the :results none” case, the command is not run at all. That’s because the “(funcall cmd body params)” call at l. 574 of ob.el (patched version) has been put in a branch that is only run if :results != none. That funcall is responsible for actually evaluating the code block. (The indentation of the patch as applied isn’t correct – the two branches of the if on l. 565 are indented at the same depth as each other, and as the if. So it’s possible that the problem is due to a paren in the wrong place. But I cannot see a way to make this approach work.) The code generating the slowdown is in backend-specific files. So, for example, a new branch needs to be added to the case statements in org-babel-R-evaluate(-session), to detect the :results none case and not read the result. I suspect that each backend will need this treatment (unless some of them share code). In the meantime, attached to this email is a patch that implements a size check on reading results. If the results file is over 10kb, it asks the user whether to proceed. You can test this by evaluating: #+begin_src sh :results silent seq 1 #+end_src 10kb of results actually doesn’t result in a very serious hang (~5sec on my system). But I chose the value as more of a sanity check – odds are (?) that very few people want to see 10k of results in the (mini)buffer. The value could be made customizable. I also chose the polarity of the y-or-n-p so that picking the default (yes) option does the sensible thing of not hanging emacs, although it thus does discard data.

Re: [O] Bug? R: Org babel block execution *drastically* slower than in ESS session directly
2012ko azaroak 17an, Eric Schulte-ek idatzi zuen: Oh!, thanks for catching this, I just pushed up a fix. This is no longer a (complete) fix for the original problem, though. (A large part of) the slowdown comes from reading the results from a temp file and transforming them into an elispy format, which is handled by the backends. Your code only prevents them from being echoed to the minibuffer. You can see this by trying your original “seq” tests. You should see them taking the same (very long) amount of time. If you set debug-on-quit to t (before evaluating the block) and interrupt emacs with C-g when it hangs, you’ll see a backtrace that goes through ‘org-babel-execute:sh’ and then ‘org-babel-import-elisp-from-file’. The presence of the former in the call stack is why I claim that per-backend fixes are ultimately needed. The latter is where my patch addresses the problem in a temporary way. I may be outvoted, but I find this approach too be overly complicated. Also, size may frequently not be the best proxy for the time which Emacs will take to ingest the results. I agree that my patch is a stopgap. But until per-backend fixes are available, this allows certain code to run that otherwise wouldn’t (at least not without hacks, such as putting NULL at the end of an R source block so that the “.Last.value” in the block is trivial). -- Aaron Ecay
Re: [O] [PATCH] org-edit-special too much space if starting with empty block

Also, you may want to reverse the if test in order to get rid of the progn. I've refactored and added comments. Finally, could you provide the patch as git format-patch and add a changelog entry to it? The patch is now in the requested format. If the commit message and inlined comments still aren't enough to explain the changes, please let me know. Thanks! -- Le org-src.el.patch Description: Binary data
Re: [O] source code disappears
Hi all, This is what my patch http://www.mail-archive.com/emacs-orgmode@gnu.org/msg62256.html is meant to fix. @Neil, can you confirm the fix? On Sat, Nov 17, 2012 at 8:41 PM, Bastien b...@altern.org wrote: I will take care of this before the end of the pretest week. -- Le
