Thanks, this solved the problem. Out of curiosity, why is not org-mode

I'm just curious because it seems that, as an example, open-office
exporting understands the language.

set italian language in LaTeX export

[Luca Ferrari]

Hi all,
this has to be trivial, but it is not working on my system (Emacs
28.2, Org 9.5.5): I set in my document
#+language: it

and I correctly got in the LaTeX buffer something like:

pdflang={Italian}}

but not something like:

\usepackage[italian]{babel}

and therefore the generation of the PDF uses English hyphenation, not
the correct italian one.
On my system I've installed the package texlive-lang-italian and if I
add the babel package line above by hand, I'm able to produce the
italianized PDF.
What am I missing here?

Thanks,
Luca

track birthdays without having them constantly being in the agenda view

[Luca Ferrari]

Hi all,
I would like to switch to org-agenda to track birthdays, but if I

DEADLINE: <2022-12-14 mer +1y>
the birthday pops in the agenda view even after it has passed. I'm

Any suggestion?

table formula for the second last row

[Luca Ferrari]

Hi all,
I've a table that is keep growing, and in the end I've added the
following to formulas:

#+TBLFM: @>$3=vsum(@3..@-1)
#+TBLFM: @>$3=round( vsum(@3..@-2)/60 )

but both overwrite the last row of the third column, while I would
like the former to be on the second last row.
Apparently I'm not able to understand how to do @> - 1, and I don't
want to place a fixed row number since the table will add new rows
over the time.
Any help is appreciated.

Imagine I've this org fragment:

Link: [[https://foo.com]]

where the link is displayed without brackets, in org mode.
I place the point at the beginning of the first visibile character,
hence the 'h', and the C-space M-e M-w and then go to another
application and paste the content of the clipboard.
I've seen that sometimes the link is copied as text, so both beginning
and ending brackets are there, but with long links the ending brackets
are not there, but it could be they I remove them accidentally.
I would like to copy only the visible part, but I guess there's no
solution unless I do something manually or configure a web package to
open the link into another application.

copying text from links makes it with a starting [[

[Luca Ferrari]

Hi all,
I'm not sure this is an org problem, rather a clipboard problem or
what else, but when I select an org link in Emacs and I copy into my
Firefox browser, the link has always a starting pair of square
brackets (e.g. [[https://...).
What puzzles me is that there are no ending brackets, as it would make
more sense to me.
Is there a way to insrtument Emacs to copy in the clipboard only the
marked text and not the org mode formatting text?

I'm running Emacs 28.2 and org 9.5.5

By the way, even if off-topic, is there a way to "dump" configuration

No, there is no buffer named cpu nor memory nor something alike in the
buffer list.

Besides, I'm now more able to reproduce the original issue: I open one
of my perl-based org files, and it takes a lot, then I switch to

Never seen nothing like this before.

Apparently I'm not able to get the profiler report written.
However, I discovered that, for instance, when I'm editing a piece of
code with regexp Emacs seems to suffer, at least it is the only
chances I had today to get it slower.
The messages buffer does not help very much:

End of ‘m/ ... /’ string/RE not found: (scan-error Unbalanced parentheses 74 82)
Auto-saving...done
CPU and memory profiler stopped
profiler-write-profile: Wrong type argument: arrayp, nil

As you can see, I cannot save the profiler report, neither by placing
a filename, nor leaving it to save in the current directory of the
file I'm editing.

Oh, I also tried to disable flyspell, but it seems to me it gets
re-enabled for the source code block I'm within (but it's just a
feeling).

Any idea?

emacs really slow when inserting a new source code block

[Luca Ferrari]

Hi all,
I'm having issues in my org files whenever I insert a new source block
(perl if that matters) with "#+begin_src perl" Emacs becomes really
slow.
I can move, paste, edit within the source block (in the same org
buffer, not an external window) but at a very slow rate.
In the messages I've only this:

Starting new Ispell process aspell with default dictionary...done
Error enabling Flyspell mode:
(No Ispell process to read output from!)

This puzzles me because the language of my org document is set to
"it", but I never found such a big problem before.
I've tried other type of source blocks, and while they appear to
behave smoothier, whenever I edit "#+end_src" Emacs has a freeze, and
in fact in the screen I see only "#+end_s" and after a second the line
completes.

I'm running GNU Emacs 28.2 (build 2, x86_64-pc-linux-gnu, GTK+ Version
3.24.20, cairo version 1.16.0) with org-mode 9.5.5.

Anything I can inspect?

therefore I would like to have a frame for ever second level title.

[O] export code snippet in beamer with different fonts

setbeamerfont{verbatim}{size=\tiny}

1) the highlight seems not to work, all the text is made in fixed size
font but in plain back (no keyword highlighted). How can I circumvent
this?
2) is it possible to tella latex to export the snippet at the max size

Thanks a lot, I'm refactoring it to my needs but it is a very good

Yes, this is what I'm doing so far. The problems I see are:
1) the image contains a footer, and LaTeX does not anything about such
footer so sometimes text can overlap with the footer. If I isolate the
footer as a separate image, how can I specify to place it to the
bottom of each slide and have beamer not placing controls and other
text on the slides?
2) I usually provide two sets of slides, one dark and one light
(printable), and therefore I suspect to provide two different
backgrounds and duplicate my org file for each theming accordingly.
Any better idea? If I can isolate the footer (which is what makes the
slides look like what is requested), is there a way to apply say a
color as background and do a "variable"-based export to beamer
choosing the color as option?

By the way, things were even worst of how I described them: the
template was Microsoft Office (not even Open Office)!

[O] from org to openoffice presentations (or make org looks like openoffice)

[Luca Ferrari]

Hi,
it seems I'm out of luck searching for a solution: I've got a library
of org-mode files that I export with beamer. So far, so good.
But know I'm forced by my management to apply an openoffice slide
layout, so I was looking for a way to export from org to open office
presentations (impress). It seems nothing so weird exists on earth.
My second thought was to put the template as a background image on all
my slides, but this is a little complicated considered my knowledge of
LaTeX and beamer (and that's why I'm using org!).
Assuming none of the above two can be answered, is there a path to get
things done? Like converting from org to markdown and then to open
office?
Anyone has a suggestion or an hint?

(and no, I don't want to rewrite my slides in open office because they
will become quickly unmantainable!).

Am I missing something?

[O] latex formula error when nested into a list?

[Luca Ferrari]

Hi all,
don't know if this is a normal behavior, but using a latex formula like this:

\begin{equation}
\begin{align}
a \times b = c \times d \\ = f
\end{align}
\end{equation}

into an org list, that is:

- \begin{equation}
\begin{align}
a \times b = c \times d \\ = f
\end{align}
\end{equation}

produces the following latex error:

! Package amsmath Error: Erroneous nesting of equation structures;
(amsmath)trying to recover with `aligned'.

while removing the list bullet makes it working. Am I doing something
wrong? Is it possible to nest formulas into lists?

[O] cannot export to openoffice

Hi all,
I'm running emacs 24.3.1 on Linux, and I've LibreOffice installed.
When trying to export an org buffer (C-c C-e) I don't have any
OpenDocument option.
I've checked and I've the zip command on my path. What else should I check?

[O] Invalid specification of styles.xml: nil

[Luca Ferrari]

Hi all,
when exporting to OpenOffice using a ott file as template I get the
error Invalid specification of styles.xml: nil, even if I placed the
property

in the org file. Regular exports to ODT works out of the box, of course!
What am I missing?

Re: [O] some key sequence transform my text in outline

[Luca Ferrari]

Apparently I found the sequence that lead to the problem: I opened a
#+begin_src on a line and then pressed TAB on such line. This folded
the following text until a new #+end_src is found, masking whole
sections. The problem is that this is no more able to be expanded.
However, editing the text file externally and removing some text after
the #+begin_src (in particular a table) solved the problem.
I'm investigating more...

Thanks,
Luca

 Hi,

 Now, with some key sequence Org eated all the text below the cursor

 with TAB, and moreover I cannot delete it without killing the whole

 I know this is not a detailed explaination, but I don't understand

 Any suggestion?

[O] avoid subscripting text

[Luca Ferrari]

Hi all,
in my file I've got some text that I'd like to be represented as fixed
font size, and therefore I write it as ~cap_mkdb~ surrounding with ~.
The problem is that, when I export the document to ODF, I got the word
following the underscore written as a subscript. Now this reminds me
the LaTeX behavior, and when I export it happens to me that LaTeX is
used for a preliminary conversion.
Is there a smart way to avoid escaping any underscore?

Thanks,
Luca

[O] inserting a path string fires the italic formatting

[Luca Ferrari]

Hi all,
this could be trivial, but if I have to place a unix path name into my
org text, without having a link, how can I prevent the mode to assume
I'm doing italic formatiing?
For instance in the text:
   - check /usr/bin/chmod
   - check /usr/lib/bla

I got italic from the first slash to the last slash in the second line.
Suggestions?

Thanks,
Luca

Re: [O] inserting a path string fires the italic formatting

[Luca Ferrari]

Thanks,
using the = symbol makes it looking less strange that a ~ (for the
backup, home directory, and so on).

 For example, by protecting those paths, declaring them as `org-code' or
 `org-verbatim', that is using the markers `=' or `~'; for example:

 - check ~/usr/bin/chmod~
 - check ~/usr/bin/bla~

[O] #+STARTUP: content question

[Luca Ferrari]

Hi,
I'd like to have my org files to show the contents of all the nodes
that have (sub)items not marked as completed/done.
Therefore the following:

* FIRST
** second
*** TODO blah
*** DONE blah

** third
*** DONE blah
*** DONE blah

should be shown when visiting the file as follows:

* FIRST
** second
*** TODO blah
*** DONE blah

** third ...


Is that possible using the #+STARTUP or org-startup-folded variable?

Thanks,
Luca

[O] using org mode and git efficiently

[Luca Ferrari]

Hi all,
I'm using Org mode to manage my coding projects, that are all based on
git. I was wondering if there are tips and tricks to use the two
efficiently, for instance storing the current head when a task is
marched as completed in org mode, so that the task can link to the
commit that completed a feature. Also having the commit text being
based on the org task one (or viceversa?) could be useful.
Anyone has an hint on how to achieve a more org-to-git integration?
I'm using magit to what it matters.

Thanks,
Luca

Re: [O] using org mode and git efficiently

[Luca Ferrari]

Thanks,
this is really close to what I was searching for (I believe that using
the bare metal mode with the commit object is what I need to track
which commit closed the task.
I'll try it.

[O] help advicing org-todo

[Luca Ferrari]

Hi all,
I'd like to advice the function org-todo to check in and check out the
clock automatically.
I've defined the org-todo-keywords so that they have a choice letter as follows:

(setq org-todo-keywords
  '( (sequence TODO(t!) | DONE(d!))
 (sequence FEATURE(f!) BUG(b!)  IMPLEMENTING(i!) |
COMPLETED(c!))
 ))

and I'd like to start the clock each time the i (implementing) is
chosen, stopping the clock each time the c (completed) is selected.
However I've a little problem doing the advice because the argument is
null and therefore I don't know which letter the user has pressed.
Anyone can provide a little help?

Thanks,
Luca

Re: [O] help advicing org-todo

[Luca Ferrari]

Thanks,
a very good advice. Now, forgive my lisp ignorance, but I've defined
the following function to do what I want:

(defun org-todo-automatic-clock ()
  Starts/Stops the clock when a task is marked as implementing or completed
  (if (string= state org-todo-fluca1978-running)
  (org-clock-in)
(if (or (string= state last-state) (string= state
org-todo-fluca1978-suspended))
(org-clock-out)
  )
)
  ) ;end of defun


the problem is how to tell the org-todo-keyword to use variables
instead of strings, since the following is not working:

(setq org-todo-fluca1978-running   IMPLEMENTING(i!) )
(setq org-todo-fluca1978-suspended SUSPENDED(s!) )

(setq org-todo-keywords
  '(
 (sequence FEATURE(f!) BUG(b!)
'org-todo-fluca1978-running 'org-todo-fluca1978-suspended |
COMPLETED(c!))
 ))

What am I missing here?

Thanks,
Luca
