I think it's different: the goal here is too reveal the file in its
enclosing directory.

[O] Is it possible for the clock table to display only clocked activities between two timestamps?

[Marcin Borkowski]

More precisely, I'd like to have a clock report, say, from today 6:00
until now?  I tried with :tstart/:tend, but didn't succeed.

(This is what I naively tried:

#+BEGIN: clocktable :maxlevel 2 :scope subtree :tstart <2014-12-10 wed 06:00> 
:tend <2014-12-10 wed 23:59>

It may not be that hard, but it will require tests.

You also need to check that the footnote definition doesn't appear
within included area, in which case it needs not be moved.

Mainly performance, and to prevent some bugs that might be introduced
with duplicate footnote definitions.

I have the collection of footnotes in the (beg end) area sorted out in the
patch I wrote last night.  Storing the triplet
  (document-path label footnote-text)
should be enough to pin down one of them footnotes.

I'm curious about the hash table.  (info "(elisp) Hash Tables") says "For
smaller tables (a few tens of elements) alists may still be faster [than
hash tables]".

For an Org document, might it not make more sense to use an alist for
this?  Or will the speed be regained when doing many includes from the
same document (since I'd check if a footnote is already in the table)?

Also, since INCLUDE is expanded before info, should I just create a new
defvar holding the table during export?  I guess that's the only way to
hold it in memory across several INCLUDE words.

[O] "org-plus-contrib" yes, "org" no!

And yet almost every time that I update my packages it installs
"org", which I've already got with "org-plus-contrib". So I then
delete the fresh "org". How can I stop it installing "org" and just

"org-plus-contrib" already includes "org" doesn't it?

[O] [org-babel R] Difference between output in RStudio and in Org Babel

[Sebastien Vauban]

Hello,

I have yet another [1] code chunk that produces very different results
whether it's executed in RStudio or in an Org document.

Here is the code:

#+begin_src R :results value replace :rownames yes :colnames yes
  df.str <- '"liste","nb"
  "item31\nitem80","2"
  "item52","1"'
  df <- read.csv(text=df.str, header = TRUE)
  row.names(df) <- c("abc", "def")
  df
#+end_src

See http://screencast.com/t/qlUVYCoLUZWA for a diff between Org Babel
and RStudio.

Of course, the problem comes from \n being interpreted as a newline, but
who's right here?

[O] Entering Repeating Scheduled Tasks in the Minibuffer

[Kenneth Jacker]

Good day!

Is there a way that I can specify a scheduled task's repeat period
within a single "time specification" in the minibuffer?  I thought
something like this would work:

Dec 25 +1y

but it neither inserts the "repeater" nor gives any error message.

I've tried various things and checked the manual, but can't seem to find
the right combination of keystrokes.


Thanks for your comments!

[O] How do I stop org-info.js showing all children recursively?

[Daniele Parisi]

When org-info.js is in (org-like) folding mode and you click on a heading,
it expands showing all of its childrend headings recursively.

Is there a way so that it shows only the first children headings?


Instead of this:

* A
Expanding into

* A
 ** B1
  *** C1
  *** C2
 ** B2

I want it to expand to just this:

* A
 ** B1
 ** B2

and this should happen at every level.

True, but then, both a small table and a small alist are very fast.
OTOH, hash tables scale better.

It doesn't matter much. I'd still favor a hash-table since it's hard to
predict an upper bound for include keywords in a document, but it's your
call, really. 

I doubt the alist or hash table will be the bottleneck.

You would need to access the alist/hash table for each include keyword,
not necessarily from the same document.

It should be in the scope of `org-export-expand-include-keyword', much
like `file-prefix'. No need for a global variable.

It is exactly hours I need.

I often work past midnight, and I really would like the day to start at,
say 3:00.  If this is not possible (AFAIK, it's not), I'd like at least
to exclude 0:00-3:00 from the clock report.

Wow.  :tstart "2014-12-10 06:00" :tend "2014-12-10 23:59" works!

Yes, that's exactly right.

Alan, I hadn't realized your code would work using the normal
keybindings. I tried it out this morning, and it works perfectly! I
really have been searching around for this kind of thing for a long
time. It seems like many people could find it useful.

For me, I'll construct a list of project files in an org-mode buffer.
Then I'll be able to easily visit those files in a dired directory and
do whatever I need to (usually copying the files to a stick drive or
other portable media to transfer to collaborators).

Thanks again!

[O] Several org-entities to be fixed.

On all the computers I've used so far, including: Windows[8, 8.1] ,
OSX[Mavericks,Yosemite], debian[wheezy], ubuntu[14.04.1], I've seen the
same problem: the org-entities symbols for phi and varphi were inverted,
and the symbol for setminus was displayed as a W with a strike-through.

Attached is a patch that exchanges between the inverted symbols, and
replaces the W symbol by the unicode 'SET MINUS' symbol.

[O] [PATCH] Adding org-babel support for rust (ob-rust.el)

[Philip Munksgaard]

Dear org-mode developers

I've been working on adding support for rust in org-babel, and this is
what I've come up with so far. It's basically just a modification of
ob-C.el. The branch is viewable at [0], but so far the only commit is
[1]. I've also attached an example of how it works. Note that you will
need rustc to run the examples, and that I've only tested them with
rust 0.12 and the latest from git.

I'm very interested in getting this merged into org-mode, as I imagine
other rust developers are, so please let me know what I can do to
help, for example if you require tests or other forms of
documentation.

Kind regards
Philip Munksgaard

I tried that yesterday and ran into some trouble, I've set ":noweb yes"
for all C++ blocks in the files and it seems that lob does not pickup on
this and will not resolve noweb references. When referencing a lob src
block, the references in that block will not be resolved. I tried
setting ":noweb yes" in `org-babel-default-header-args´ and in
`org-babel-lob-header-args´ with no success.

[O] org-babel for prolog

[Bjarte Johansen]

Hi,

I have started to implement org-babel support for (swi-)prolog. I have gotten 
to the point where I can execute a goal in an external process and have the 
result show up in the org file. I am now working on getting the session to work 
correctly. It runs and prints, but it doesn’t do the correct thing in the 
inferior-mode-buffer and the output is garbled. I still have some work ahead of 
me.

I just thought I would let you know in case someone was interested in following 
the progress or maybe also in helping me. I have the mode hosted in its current 
state here https://gist.github.com/ljos/2e346333e1b7bfd56d05 
 . 

And before you ask, yes, if I get this into a working order, I would eventually 
be interested in getting this into either contrib or core.

Regards,
Bjarte

[O] Patch to implement sorting Org tables by IP address

[Jon Snader]

There is currently no easy way to sort an Org table by IP address. The only 
method I could find involves selecting the IP addresses in a rectangle and 
piping them to sort with a complicated sort recipe. Even though I am not a 
system administrator, I sometimes need to maintain tables that I’d like to keep 
sorted by IP address.

The attached patch implements sorting Org tables natively.

I’ve just completed the FSF Copyright assignment process—let me know if you 
need details.

Very good.

The above "not enough input" contradicts with "no input" from the
docstring of orgtbl-aggregate-apply-calc-1arg-function:

Empty value is returned when all input values are empty.

If this function would follow its docstring by having "(if (cdr vec)"
also for sum, min, max and prod then the user could benefit from
adding "E" and/or "N" or not in the mode string of the TBLFM:

#+TBLNAME: test

| a|   2 |   2 |

== "nan" || "$3" == "nan", string("NA"), if($2 > $3, string(">"),
if($2 < $3, string("<"), string("eq"; E
#+END

The current orgaggregate for comparison:

| Item | sum(Value_1) | sum(Value_2) |   |   ||
|--+--+--+---+---+|
| a|4 |2 | 3 | 3 | >  |
| b|2 |4 | 3 | 3 | <  |
| c|0 |4 | 2 | 2 | <  |
| d|0 |0 | 0 | 0 | eq |

One could still get the current behavior by adding the column formula
~$2 = if("$2" == "nan", 0, $0); E~ etc. for the aggregated columns.

What do you think?

An additional, more convenient and more natural way to add headers for
a TBLFM column formula could be to add support for this (matches the
TBLFM of the example of my other post from today):

:cols ("Item" "sum(Value_1)" "sum(Value_2)" "Mean of non-empty"

OK, now I feel sheepish.  I assumed from the screencast.com URL that

There’s no convention in org tables that “\n” (i.e. two characters,
backslash + n) means newline (i.e. one character).

> In this case, I'd expect the same as in RStudio; that is, no multi-line

What R’s console shows you (either RStudio or vanilla R) is a “human
readable” representation of the data frame, which includes doing
things like changing the newline character into a \n escape sequence
(and other stuff, like padding the columns with spaces so they all
line up vertically).  But when Org communicates with R, it asks for a
machine-readable version, which doesn’t include such niceties.  When
that machine-readable version includes a newline character in a data
field (as your example table does), org doesn’t know what to do and
messes up.

On a substantive note, “as long as Emacs runs” is not quite accurate –
it’s until the interpreter process exits, which could happen because the
user kills it, it crashes, a piece of code which is executed tells it to
exit, ...

I think something should be said like “If the session name is empty, a
default name based on the block’s language will be used.”  The session
name also becomes the interpreter process’s buffer name, and leaving
:session empty does not generate a buffer named “” (the empty string).

(It’s also a perverse but true fact that if you specify the same session
name for two blocks of different languages, they will both send their
code to the same interpreter process.  But for two blocks in different
languages with an empty :session, they will each use their language’s
default name.)

>PS  What is the meaning of "(=>F)" that appears at the end of the

I believe this means org has chosen the future option of an ambiguous
input. e.g., it is December 10th. I use C-c . to create a timestamp and
simply put in "9". The closest date that matches is December 9th, but
there is a setting (I think org-read-date-prefer-future) that makes it
prefer to choose a date in the future, so it is letting you know that it
is opting for the future date instead of the closest date.

I could be wrong, but that is my understanding.

My mistake.Fixed to:

Well... Many different topics here.First of all, empty input & empty
output are unrelated. So let us take them one at a time.

* Input
In the spreadsheet formulas, we have those modifiers:
- E = keep empty fields when counting input vector size.
- N = replace non-numbers (including empties) by zero.

The first version of orgaggregate behaved as thought it had the EN
modifiers.The latest version behaves as thought it had no modifiers at all.

For the shake of consistency, it would be nice to have specifiers in
orgaggregate. E & N, of course, but also p7 (precision 7 digits), %.3
(three decimal places after dot), F (fraction), and so on.

* Output
If a function is able to compute a result, then it should give it. If
for any reason it is not able to compute a result, it should tell it in
some way. Right now, orgaggregate signals problems by leaving a blank
output. But it could be anything else: nan, NA, #ERROR, vmean([]), 1/0,
whatever.

The =sum= aggregation is always able to return a value, even for a zero
length input vector, in which case the sum is zero. On zero length
vectors, =prod= gives one. The =mean= aggregation has a hard time
telling what is the mean of a zero length input vector.

Here is how the spreadsheet handles those cases (without modifiers):
  |   |   |   | sum |  mean | prod |
  |---+---+---+-+---+--|
  | 1 | 2 | 3 |   6 | 2 |6 |
  |   | 2 | 3 |   5 | 1.667 |6 |
  |   |   | 3 |   3 | 1 |3 |
  |   |   |   |   0 | 0 |1 | <--- see
  #+TBLFM: $4=vsum($1..$3)::$5=vmean($1..$3)::$6=vprod($1..$3)

This is correct. Orgaggregate should behave in a similar way.
Fortunately in its latest version it does.

* Summary
Modifiers are lacking in orgaggregate for it to be fully consistent with
the spreadsheet. If someone knowns how to add them easily...

Why not?  Or perhaps I should ask: how is it determined whether

Thanks a lot!  I've noticed a couple of minor issues - hopefully I'll
fix them when I get time and then maybe submit a patch.

[O] Bug: org-babel-script-escape misses a lonely double quote [8.2.10 (8.2.10-23-g1ec416-elpaplus @ c:/Users/jowik/.emacs.d/elpa/org-plus-contrib-20141208/)]

[Johan W . Klüwer]

I encountered a problem with unmatched double quotes in an org-babel
table of results. Seems like the issue lies with escaped double quotes:

  (org-babel-script-escape "[[\"a\", \"b\\\"\"]]")

  returns error >  Invalid read syntax: "] in a list".

Adding the following after line 41 of org-babel-script-escape appears to
fix the problem.

  (92 (if in-single ; \
 (append (list 92 34 out))
  (setq in-double (not in-double)) (cons 92 out)))

We now get

  (org-babel-script-escape "[[\"a\", \"b\\\"\"]]")
  (("a" "b\""))

Thanks Grant.

My emacs version is in the sig, and my org-version is "Org-mode
version 8.2.10 (8.2.10-23-g1ec416-elpaplus @
/home/boudiccas/.emacs.d/elpa/org-plus-contrib-20141208/)" so we're
in agreement, but still it happens. I've checked everywhere in my
"init.org" and I don't have a spare "(require 'org)" floating
around, its not in there at all!

I'm puzzled!

My guess is that the version of Org that comes bundled with Emacs is
being loaded. If so, you could try renaming the `org` directory in your
Emacs installation's `lisp` directory to e.g. `.org` so that it's not
found by default, then restart Emacs.

I'm very glad it helps, but Bastien should get all the credit here (I
only tweaked the solution he sent me).

My main motivation for using this is that I have some code to preview a
file using Quicklook (I'm on OS X), and code to open a file in an
external app when in dired, so it's quite useful for files that emacs
cannot display:

 (dired-get-marked-files)))
  (bury-buffer proc

(defun open-in-external-app ()
