special blocks extras

[Michael Welle]

Hi,

I wanted to play with special blocks and started by installing the
package org-special-block-extras and defining a new block:

(org-defblock hmwfoo nil (reps 3)
  "Ahoj"
  (message "ahoj: %s" contents)
  (org-parse (s-repeat reps contents)))

For the tests I started with exporting to html.

A link like [[hmwfoo:][oink]] seems to work, I see three concatenated
oinks.

A block like

#+begin_hmwfoo
oink
#+end_hmwfoo

exports to only one single oink. According to my understanding both, the
link and the block, should be equivalent?

Well, then I activated the special block extras minor mode before
exporting and things got strange. The link still seems to work, but the
block results in an html page rendered like this:

#+end_export oink

oink

oink

#+begin_export html

Three oinks, but lots of line breaks and the export markers are part of
the rendered page. Hm, that's not what I expected ;). Do I use it the
wrong way or is there a bug hidden somewhere?

Exporting images to different output formats

[Michael Welle]

Hello,

I want to export to different output formats. Trouble is the way ox-gfm
exports images. So I thought, hm, why not utilise macros to abstract away
the differences. Well, that escalated quickly:

#+macro: img_gfm (eval (concat "#+begin_export md\n![img](" $1 " \"" $2  
"\")\n*Abb.: " $2 "* (Quelle: " $3 ")\n#+end_export"))

#+macro: img_latex (eval "foobar")

# Image export for Github flavoured markdown
# $1 path to image
# $2 caption
# $3 source
#+macro: img (eval (cl-case org-export-current-backend ('gfm (concat 
"{{{img_gfm(" $1 "," $2 "," $3")}}}")) ('latex "{{{img_latex}}}") (t "barfoo")))


{{{img(./foo, foo, barfoo)}}}

That kind of works (and breaks if I want commas in the caption), but is
ugly as... and doesn't get better if I implement the other output formats.

Maybe syntax like @@latex: ...@@ would help. But no, I think that is
defined in the specific backends, not as a general mechanism.

So, how can I do it better?

funnily I observed something similar while generating semester projects
for my students.

Example:

#+name: seprj_conf_table

| xxxdrei | ${eins} |

#+begin_src sh :session foo :var conf=seprj_conf_table :separator =

older Org:

Backport commit 8dacd8cd9 from Emacs

I smell something strange going on here ;). For every Org related
question I had in the last few weeks I found at least one other person
that had the same question roughly at the same time.

I use Org to generate projects, import stuff, set permissions etc. on
several servers for a software engineering course. I think it would be
nice to separate the student's personal data in Org tables from the Org
code that get checked into a repository.

My first attempt was :var data=data.org::remote-table, but the familiar
double colon didn't work, the single colon indeed did the trick.

Generating documentation about Org from random org file

[Michael Welle]

Hello,

the subject is a bit unmeaning, so let me explain. I have an Org file
implementing a real use case. The file consists of documentation of the
use case, of code blocks and all the other stuff. That's mostly fine.

Now I want to use this file to showcase the use case a bit, but also to
produce documentation about Org, about how to solve a problem with Org.
Therefore I want to show the code blocks, but this time with the
begin/end tags, with header parameters etc. Is there a nice way to do
that without too much code duplication and convolution? Or should I just
copy the file and separate the use case and the showcase one?

interestingly I asked a similar question in #org-mode yesterday. I came
up with this approach:

* table test
** user data
#+name: userdata
| uid | name | foo   | bar  |
| a2s | a2   | afoo  | abar |
| b2s | b2   | bfoo  | bbar |
| c2s | c2   | c foo | cbar |

** code
#+begin_src sh :var userdata=userdata :separator , :results raw
  echo "$userdata" | while read line ; do
  IFS=','
  echo "$line" | while read u n f b ; do
  echo "u: $u n: $n f: $f b: $b"
  done
  done
#+end_src

This looks a bit clumsy, but should also work with shell that doesn't
support (2D) array type variables.

thanks for bringing that up again. Your example works, of course. After
further inspection I think that variables kill my example:

This code block comes from a file I processed with org-babel-lob-ingest.
o-b-l-i returns the correct number of code blocks in that file and org-bab

#+name: boing
#+begin_src elisp :var range=42
(message "Hello, crude world: %s" range)
#+end_src

This comes from the file where I want to use the code block:

|+|
| <2020-02-19 Wed>--<2020-02-21 Fri> | #ERROR |
#+TBLFM: $2='(org-sbe "boing" (range 23))

That fails. After removing the variable from the code block and from
org-sbe it works as expected. It works as well if I copy the code block
including the variable into the file with the table. Might be a bug or
my own stupidity?

org-sbe and code blocks in a different files

[Michael Welle]

Hello,

I can execute code blocks in different (separate?) files like this:

#+call: ../lob.org:convert-time-range-to-days(range="<2020-02-19
 Wed>--<2020-02-21 Fri>")

That is great. Can I call the same function from a table function?
org-sbe doesn't support the above notation extended with an Org file
name, I think.


Second, I try to concentrate useful reusable code blocks in one file,
lob.org in my case. That works. But I feel that I need some of the elisp
based code blocks as code blocks, that I can execute, as well as
separate elisp forms that I can eval from elisp code. How to deal
with that?

Ideas:

Having two code blocks per function: one with the actual elisp code that
can be tangled and a second one that just evals the form and can be used
as a, well, code block usable with #+call?

Or should I give them names like func and func_code (that's the one with
actual elisp code) and write an elisp form that grabs all code blocks
named *_code and evals them at start-up to bring the forms into the
environment?

Other ideas are also welcome.

Re: #+call and strange behaviour

sorry, for the noise. Just minutes after posting the question I

Hello,

in a file named test.org I have an elisp src code block and a line like
this:

#+call: test.org:hcw(d="foo")

C-c C-c on that line executes the code block just fine. Copying the line
to another org file and pressing C-c C-c results in nothing obvious. On
the other hand, putting a code block in this other org file C-cC-c works
as expected again on a line such as this:

#+call: other.org:hcwother(d="foo")

It seems like it doesn't work if one references a code block in a file
that isn't the current/own file of the reference. Any hints on this,
please?

well, I don't do this for Emacs specifically, but for the compilers,
tools, etc. I need in operating system and systems programming courses.
A surprisingly huge number of students struggle with installing the
needed tools on their systems and it is always very time consuming for
us to try fix their problems (different OS, different compilers, etc.
ppp.). Since about a year I hand out pre-configured VM images that can
be imported into Virtualbox, VMWare, etc. That way we only need to
support the installation of a single product (we encourage the students
to use Virtualbox). That works out quite good. Typical problems are:
student can't figure out that their disk is full, virtualisation
extension of the hardware is disabled in firmware, student uses hardware
with not enough RAM or disk capacity. Very rarely the students own
hardware that don't allow to enable the virtualisation extension, I had
that once or twice. And there are always a few students who seem to have
strange random problems and when we ask for details the students don't
show up again.

well, I think there are only wuerg-arounds to gain the desired
behaviour. First, you can use a sexp to specify the days on which your
task will be inserted into your agenda:

SCHEDULED: <%%(memq (calendar-day-of-week date) '(1 2 3 4 5))>

But with that your task is done when you set it to done. Something
like the following isn't perfect, but seems to work:


** TODO foobar
   DEADLINE: <2020-01-04 Sat +1d>
   SCHEDULED: <%%(memq (calendar-day-of-week date) '(1 2 3 4 5))>

I thought that behaviour is natural, scanning dirs for files and opening
them is a costly operation. But a week ago I changed from rotating rust
to solid state disks and that behaviour did not change much. I expected
a speed up, but mee.

since no one answered yet, there are some similar threads. IIRC the way
to go is to use elp for profiling.

Well, on my laptop the initial agenda run takes about 7s or so (150
agenda files) using the current day/week agenda ("a"). All subsequent
(after loading the files) agenda runs are fast (split second I would
say). I had some performance issues in the past caused by SCM. Emacs
tried to check if every file is checked out in the latest version. That
slowed down the process a lot (starting 150 mercurial processes in
sequential order, checking results, etc.). The initial run doesn't
bother me much. I bound the initial agenda run to an idle timer at Emacs
start.

I asked something similar earlier this year (concatenating compiler

wget -c "http://ben.akrin.com/crackzor/crackzor_1.0.c.gz; -O-

I'm not sure if I understand your problem correctly. # starts a comment
in shell, and $ denotes (among others maybe) a variable name. In that
sense 

#+begin_src bash
$ls
#+end_src

delivers the value of the variable ls. The semantic of $ is not to
execute the command ls as a non-root user. Same goes for #. If you want
to put your own semantics into $ and # it might be better to not use a
bash code block.

If you want to note that some commands in a script needs root privilege,
maybe something like this would do the trick:

#+begin_src bash
ls
su - -c 'fdisk /dev/rdsk/c0d1/p0'
emacs&

Hm, the property values can be functions that get evaluated to get the

Well, maybe it's just me, but the headings do not look vertically
centered. They jump up and down a lot while flipping through the slides.
For slides with a lot of content the heading is a bit more to the top of
the page, for slides with less content the heading 'sinks down' to the
center of the page. If you look at page 20 the heading is just above the
vertical middle of the slide, not at the top.

That jumping of the headings is one of my main issues, I think it's not
acceptable. 

I can glue the headings to the top of the page (setting reveal-center to
nil). But then I have trouble centering the content. I tried with
putting in an empty  of a certain height. That works, for certain
meanings of work. The trouble is finding the height, which also might
change with changing resolution and content.

I have the feeling that all that can be fixed with using flex layout.
That means changing the CSS entirely, I think. But that is a lot of
work. On the other hand, I'm not a CSS expert.

Don't get me wrong, reveal is fine. It's just that I can't (within an
appropriate amount of time) produce a slide with the layout I
want (header at the top, footer at the bottom, content centered).

I guess that's the downside of using html. Every render engine has a
certain amount of degrees of freedom on how they can render a html
construct. To tackle that problem my idea was, as a first step, to
produce slides based on reveal.js. That way I can use features, that
might be handy when it comes to teaching stuff. And maybe (I don't have
numbers etc., so I can be totally wrong) it is more likely to have a
more or less decent web browser at hand than a pdf viewer, esp. when it
comes to mobile devices.

As a second step, I wanted to use decktape to generate a pdf file from
the html based slides. That gives me a format with a more reproducible
layout (assuming that the render engine in decktape generates the same
output for subsequent runs).

Re: [O] org-reveal: content side by side

[Michael Welle]

Hello,

I just wanted to tell you how my adventure in reveal land ended ;).
Well, I spent a couple of hours last week and the better part of this
weekend with css. I could produce a slide similar to [0]. I couldn't
solve the structure problem I described earlier. And what put me off
in the end is, that I wasn't able to produce a slide like the one in [1]. 

Looks easy, eh? A header at the top, a footer at the bottom and a lot
of space in between. In some cases, like in [1], I wanted content (e.g.
Ich...OS/2 Warp 4) to be centered horizontally and
vertically between the footer and the header. 

Maybe it's my lack of understanding of css (I set colored borders for
every element and used the browser's web inspector tool to figure out
what happened.), maybe the css must be rewritten using flex layout, I
don't know. Until I will get bored again, I will stick with Org's beamer
export :)[2]. But anyways, if you want to share your experience with
ox-reveal, you are welcome.

thanks, I will check it out. I have to say it takes quite some time to
get a presentation that looks as good as the beamer based presentation I
use as an example.

The current issue I have is this. I have a structure like this:

* foo
** foo1
** foo2

Basically foo acts as a container for the content. I want foo to appear
in the table of contents and I want two slides, foo1 and foo2, and none
for foo. I'm nearly there, but I don't know how to suppress the
generation of a slide for foo.

I could use this structure:

* foo1
* foo2

But I miss the container that groups the content for me, the presenter.
And what is more important, I don't know how to get foo into the TOC (in
a nice way).

Or I could use:

* foo1
** foo2

Which seems to have even more issues: the content of foo2 is on the same
level as the content of foo1, it's not sub-content. The headers of the
slides have different sizes then, etc.

[O] org-reveal: content side by side

[Michael Welle]

Hello,

a new year, a new tool ;). I try to shift a bit away from beamer based
slides to a format, that allows me to create nice html-based slides and
nice pdf-based slides from the same source. It looks like org-reveal and
decktape might be what I want. Maybe. To find out I try to convert an
org-beamer based set of slides.

With the second slide first problems... revealed ;). How can I position
content, let's say images or images and text, side by side? Using
org-beamer I would do something like that: 

#+BEGIN_CENTER
#+ATTR_HTML: :width 25% :center
[[./img/1290250232.pdf]]
#+ATTR_HTML: :width 25% :center
[[./img/Machovka-chip.pdf]]
#+ATTR_HTML: :width 30% :center
[[./img/SAN-Disk-Array-SCSI-29.07.11.pdf]]
#+END_CENTER

That gives me three scaled images in a row (s. [0]).

That doesn't work with org-reveal. Putting the content into a table
works, kind of. But I don't know how to add the attributes used for
scaling, styles etc. And it will get complicated if I want to compose
the slide out of three or more blocks, e.g. something like that:

  aaa bbb
  aaa bbb
  ccc
  ccc

Any hints on that? I guess the question boils down
to how to produce a slide like the one in [0] with org-reveal.

having access to an archive is a good thing. On the other hand, I don't
make much use of the older postings in my own archive (about 65k
postings), maybe because Org changed so much over time.

it is from org-id. It gives the heading a unique id and uses that to
reference the heading instead of the heading's text. That way the
reference does not become invalid if the heading's text changes. And, as
a side effect, it works around the problem you found.

No, it doesn't solve the problem. I guess the problem is that the
heading's text is fed to a format form or something like that.

interestingly I did not found a good solution after a bit of thinking...
The best I could come up with is something like this (which doesn't work):


#+name: foosql
#+BEGIN_SRC sql :dbuser weather :database environment :engine postgresql
select time, temperature from weather limit 10;
#+END_SRC


#+begin_src emacs-lisp :results raw :var hosts=(list "db1" "db2" "db3")
(dolist (host hosts)
  (org-sbe foosql (concat ":dbhost " host)))
#+end_src

Error: Symbol's definition is void: host. I guess that's caused by the
way the macro is evaluated. And the result, if any, of the sql query had
to be transformed back into a nice table for some use cases.

Using other means of calling a code block, like #+call etc., aren't
suitable for usage in a loop. So maybe someone can come up with a nice
solution ;).

it basically means that state is preserved for code blocks that run in
the same session (as long as the interpreter is running). Or in other
words, imagine two code blocks: the first sets a variable, the second
prints the variable. Without sessions the code blocks run in different
shell instances and the second block doesn't 'see' the variable set by
the first code block. But if both run in the same session, the second
code block 'sees' the state left by the first code block.

oh, I should add that. Albeit the example I posted earlier runs locally,
my goal is to execute the shell code on a remote machine. But the
result is the same with both scenarios.

#+BEGIN_SRC shell :session n42 :dir /localhost: :shebang "#!/bin/bash"

[O] ob-shell, output and continuation prompts

this code block:

#+BEGIN_SRC shell :session n42 :shebang "#!/bin/bash"

echo "u: $i"
done
#+end_src

produces this output when it first runs:

After the first run, subsequent runs produce this output:

#+RESULTS:

| u: | bb ||
| u: | cc ||

If I set :session to none the output is always like follows:

#+RESULTS:

[O] ob-shell and remote shells

[Michael Welle]

Hello,

I want to execute shell blocks like follows:

#+BEGIN_SRC shell :session n42 :dir /127.0.0.1: :shebang "#!/bin/bash"
echo los
echo $SHELL
echo $BASH
echo ready
#+end_src

The trouble is that the shebang property doesn't work in this case. The
script is executed with the login shell of the user and fails because of
syntax errors (for instance, if bashisms are used in the script).

With my minimal and dangerous knowledge about Org's source code ;), I
think the following might work (from ob-shell.el):

(defun org-babel-sh-initiate-session ( session _params)
  "Initiate a session named SESSION according to PARAMS."
  (when (and session (not (string= session "none")))
(save-window-excursion
  (or (org-babel-comint-buffer-livep session)
  (progn
(let ((explicit-shell-file-name (xxx)))
(shell session))
;; Needed for Emacs 23 since the marker is initially
;; undefined and the filter functions try to use it without
;; checking.
(set-marker comint-last-output-start (point))
(get-buffer (current-buffer)))


Note the let form. Further tasks that have to be done is to add the
shebang key to _params, which I hope is available at all places where
o-b-s-i-s is evaluated. Further at (xxx) a regexp etc. is needed to
transform the shebang line to a shell path suitable for e-s-f-n.

Any opinions, please? Depending on the opinions I will implement the
approach this week and see if it works as expected.

I use this ad hoc implementation:

  "Go up to a section of level `level', if there is any, and then call 
`org-export-dispatch'. `level' defaults to 1."
  (interactive)

yepp. Maybe add a 'braininess' factor to every task. Tasks, that need a
lot of thinking, let's say hacking, have a higher 'braininess' than, for
instance, sharpening pencils. Depending on the 'braininess' of the
interrupted task add another 15 or 30 minutes to the interruption
account.

something like this would do the trick:

[O] Creating consecutive time stamps

[Michael Welle]

Hello,

the subject is a bit fuzzy, so let me depict an example use case:
creating an appointment for a multi-day conference. I use a capture
template with the placeholder %T for that (I use the same template for
single day appts, which occur more often.). Then I adjust the inserted
time stamp, add --, press C-. and add the second time stamp.

So far, good. The itching point is that the calendar view for the second
time stamp starts today, again, not at the date of the first time stamp.
I can dimly remember -or I think I do ;)- that that was different in the
past, maybe with a different template. Any ideas for a 'grey ointment'
that stops the itching?

Yes. Trouble is nobody could explain to me what I have to sign and what
that means in the legal system I'm in. My last attempt to find that out
was in #emacs. It's about 'transfer of copyright' to the FSF. If I

Even if we assume its quality is high enough to integrate it into Org,
there might or might not be another problem: I haven't signed the FSF

someone can sneak it in ;). I can repost the code, stating that it is

[O] Temporary cancelling recurring tasks

[Michael Welle]

Hello,

I want to temporary cancel recurring tasks. Let's say I have tasks, that
only make sense when I'm in my office. Now I'm away for a few months.
The tasks would clutter my agenda. I could comment them, archive them or
use org-cancel-repeater and set the task's state to DONE. But all that
makes it hard to restore the previous state when I'm back in my office.

I think, the clean solution is to set the state of the task to CANCELLED
or STOPPED or something like that, to deactivate the recurring task.
When I activate the task again, the scheduled date and the repeater
should be restored. To achieve that, I tried the following:


;;
;; Deactivate/Activate recurring tasks
;;


;; Prior to Org commit 7d52a8c3cc86c8ce03eda006752af1ab4bed4316
;; there seems to be no way to set the repeater of a, let's say,
;; SCHEDULED property programmatically. So we use this function.
(defun hmw/org-schedule-set-value (val)
  "Sets the value of the SCHEDULED property. This allows for
setting the repeater as well."
  (interactive)
  (save-excursion
(org-back-to-heading t)
(let ((bound1 (point))
  (bound0 (save-excursion (outline-next-heading) (point
  (when (re-search-forward
 (concat "\\(" org-scheduled-time-regexp "\\)")
 bound0 t)
(replace-match val t nil nil 2)

(defvar hmw/org-scheduled-property-backup "DISABLED-SCHEDULED"
  "Back up the original value of the SCHEDULED property into this
property when deactivating a recurring task. The value is rescued from
this property to initialise the SCHEDULED property when activating the
task again.")

(defvar hmw/org-activated-recurring-task-state "TODO"
  "Switch a recurring task to this state after activating.")

(defvar hmw/org-deactivated-recurring-task-state "CANCELLED"
  "Switch a recurring task to this state after deactivating.")

(defun hmw/org-deactivate-recurring-task ()
  "Deactivate a recurring task. The value of the SCHEDULED property is
stored in the property referenced by `hmw/org-scheduled-property-backup',
so it can be restored later. The task's state is set to the value of
`hmw/org-deactivated-recurring-task-state'." 
  (interactive)
  (when (org-entry-is-todo-p)
(save-excursion
  (org-back-to-heading t)
  (let* ((pom (point-at-bol))
 (val (org-entry-get pom "SCHEDULED")))
(when val
  ;; Remove the time stamp meaning. We don't want active
  ;; timestamp to trigger any actions for the deactivated
  ;; task.
  (setq val (replace-regexp-in-string "^<\\(.*\\)>$" "\\1" val))
  (org-entry-put pom hmw/org-scheduled-property-backup val)
  (org-entry-put pom "SCHEDULED" nil)
  (org-todo hmw/org-deactivated-recurring-task-state))

(defun hmw/org-activate-recurring-task ()
  "Activate a previously deactivated recurring task. The value of the
SCHEDULED property is retrieved from the property referenced by
`hmw/org-scheduled-property-backup', which is then deleted. The task's 
state is set to the value of `hmw/org-activated-recurring-task-state'."
  (interactive)
  (when (org-entry-is-done-p)
(save-excursion
  (org-back-to-heading t)
  (let* ((pom (point-at-bol))
 (val (org-entry-get pom hmw/org-scheduled-property-backup)))
(when val
  ;; For Org commit 7d52a8c3cc86c8ce03eda006752af1ab4bed4316 or
  ;; later use this
  ;;(setq val (replace-regexp-in-string "^\\(.*\\)$" "<\\1>" val))
  ;;(org-entry-put pom "SCHEDULED" val)
  
  ;; For older Org use this
  (org-entry-put pom "SCHEDULED" val)
  (hmw/org-schedule-set-value val)
  
  (org-entry-delete pom hmw/org-scheduled-property-backup)
  (org-todo hmw/org-activated-recurring-task-state))
 

The idea is to store the value of the SCHEDULED property somewhere when
the task gets deactivated. Later, on activation, the property value is
restored.

There are two variants. The one above, which should work for Org prior
to commit 7d52a8c3cc86c8ce03eda006752af1ab4bed4316 and also for later
revisions. And one for that commit and later. If you use the newer Org
revision, you optionally can get rid of the function
hw/org-schedule-set-value and follow the comments in
hmw/org-activate-recurring-task.

it's quite a hack. I don't want Org to evaluate source code blocks
without confirmation. This could lead to all sorts of trouble. On the
other hand, there are a few source code blocks, that I want to eval
without confirmation. So I use this:


(defun hmw/org-post-publish-export-confirm-evaluate (lang body)
  (not (string-match "^#post publish exporter" body)))
  
(setq org-confirm-babel-evaluate 'hmw/org-post-publish-export-confirm-evaluate)

A source code block looks like follows:

#+BEGIN_SRC shell :exports results :shebang #!/bin/sh :var 
SRCDIR=(expand-file-name (plist-get plist :base-directory)) :var 
DESTDIR=(expand-file-name (plist-get plist :publishing-directory))
#post publish exporter
(
echo "Starting esxwithforeman.org $(date)"

cd ${SRCDIR}

echo "Finish esxwithforeman.org $(date)"
) >> /tmp/c0t0d0s0_publish.log 2>&1
#+END_SRC

As you can see, this is not a security feature, esp. now that I
published it ;).

I will have a look at it later this week.

If you have enough information to perform a semantic merge, there should
be also enough information to spit out a diff. Defining what a
difference is in Org would be a starting point. An implementation will
follow then. Maybe a task for the next winter ;).

ohschockschwerenot, I found it. I set org-confirm-babel-evaluate to a
function that does look at the body of the code block and then decides
if it should be executed without confirmation or not.

I'm not sure, why that is a problem. In the case of the examples, the
function returns t and that is the default value of o-c-b-evaluate.

Uhm, no ;). Unfortunately the column and the script block share the same
name in the example. That should be no problem, I changed that and still
no success with current Org. Org 8 works as expected.

well, the docstring is a bit misleading, IMHO. Current source code block
means that the function looks around to find a source code block. I
though, it means the source code block 'I am in' at the moment.

I've tracked it down to org-babel-check-confirm-evaluate so far. In the
let*, export and eval are nil. The 5. element of info is nil, that means
(goto-char (nth 5 info)) will barf. Hmm.
