Re: [O] Just sharing another orgmode use: usability tests

[Eduardo Mercovich]

Hi Karl.

+ automatic task clocking, including automated time stamping of 
every observation.



You seem to use headings for any events.
If list items does the trick as well, you can take a look at 
timers
for doing the clocking thing: 
http://orgmode.org/manual/Timers.html


Totally agree, that's exactly what I use now. :)
Lists are used inside each task, at 1 item per (short) 
observation. 

+ observation tagging (there are repeating patterns of use or 
interaction problems or sources that you could catch on the 
fly, so any observation could be related to those common 
issues).


You already mentioned templates. I'd go with yasnippets for that 
as well.


Sorry I wasn't clear, I meant more the use of tags related to 
common observed patterns mark and select after (with sparse tree) 
those in which that pattern or issue is relevant. Great to group 
things (tasks, observations, etc.) related to the same issue. 

+ automatic filling of User/task-results-and-time matrix (the 
most fundamental metric of usability tests).



Wow, this would be great.


Yes, but for that I have to learn Lisp. ;)
I'm starting with "An Introduction To Programming in Emacs Lisp" 
by Robert J. Chassell. Just minutes a week sadly, but this is what 
I can do now. :)


In the document structure we have: 
* Users,

** Pre-task interview
** tasks (with TODO states as indicators of success|failure|so-so; 
  maybe we can use properties).

- each one with one or more timer entry
- so total task time is the last item timer value,
** Post-task interview

To make the User/task-results-and-time matrix we'll have to walk 
the hierarchy and get for each User the sequence of tasks, and of 
each, the success (or not), time and tag (issue) related and put 
that in the results matrix. 

Since I couldn't find other references about orgmode used for 
usability, I am organizing an informal workshop to share this 
experience next week with 10 people or so from the usability 
community in Buenos Aires.
If someone is interested, we can arrange another in English after 
this 1st one. ;)


Best regards...

Yes I found this nice piece of code  

It switches to svg if backend is html and to raw latex if backend is
latex. You only have to tweak it your needs.

#+header: :file (by-backend (html "tree.svg") (t 'nil))

  child { node [circle, draw, fill=green!30] {3} }
  child { node [circle, draw, fill=yellow!30] {4} }};
  \end{tikzpicture}

#+begin_src emacs-lisp :results silent

Re: [O] Slow usage of capture templates

[Tim Cross]

Probably no real help, but win10 is (or soon will be) bundling in bash
shell, which may address many of the reasons to use Cygwin. From posts
I've seen on a number of lists, I would not be surprised to see cygwin
slowly decline into obscurity. I see little interest in the emacs devel
list for cygwin since the native windows version has matured (and it has
been suggested, is the largest emacs user base).

Having bash, a native emacs and even a 'better' system shell in
powershell (better than bat scripts and VB that is), at some point, you
will likely have to switch and I can say, it is much less distasteful
than it was (I've been using Linux since 1993 and Emacs since 97 and am
also forced to run windows at work).

Alternatively, do what I actually do - run vmware and Linux as a
virtual - technically, I'm running the work SOE and within policy! When
I absolutely have to do things in windows, I use native Emacs and a
small amount of powershell, but plan to use the bash shell once I find
time to sort it all out.

I put this at the bottom of each Org file and it works well:

[O] setting local variables

[Eric Abrahamsen]

Hi there,

I'm writing an Emacs manual in Org, using
https://github.com/tarsius/ox-texinfo-plus to make things a bit easier.

I'm trying to locally set `sentence-end-double-space' to t, to conform
to the Emacs manual style. If I set it at the top of the file with:

-*- sentence-end-double-space: t -*-

That line appears in the exported *.texi/*.info files (which I don't
think it should!).

I'm not able to set it at the bottom of the file, either, with a "Local
Variables:" section, as the Org comment syntax isn't recognized by
emacs (or maybe it's the indentation?), and the elisp comment syntax is
exported literally.

How do you all set local variables in Org files to be exported?

Thanks,
Eric

Yes, I'll try that, too.

The next iteration of the patch should include ob-vala.el itself, some

Re: [O] Finding calc/elisp methods

[Adonay Felipe Nogueira]

Hi, you can find such information in the Calc Mode info pages:

[[info:calc]]

Avoid the commands between parenthesis which start with "calc-" because
these are actually Emacs Lisp procedures --- if you would really need to
use such, you would have to write the formula as a Emacs Lisp notation
and as far as I know, we can't mix Emacs Lisp procedures together with
Calc commands in the same formula, like so:

vmax([2, 3, '(max 2 4)])

The example above would cause an error. 'max is a "native" Emacs Lisp
procedure that would return the maximum value from the values given.

Happy hacking! :)

A long time ago, I struggled with this question and I don't know
of a satisfying answer. For a while, I went directly to the
following info node and looked around:

(info "(calc) Matrix Functions")

Now I just remember the initial "v" :-)

But there are other calc functions that are useful as well, so this
will certainly not suffice in general. But it's a start.

Putting together a macro seems like the best option.  Recall that you can use 
elisp in macros by placing it between `(eval’ and `)', so the following emits 
“def’ in all but latex exports and “abc” for latex.

#+BEGIN_SRC emacs-lisp
(defun foo (a b) (if (eq 'latex org-export-current-backend) a b))
#+END_SRC


#+MACRO: bar (eval (foo $1 $2))


{{{bar("abc" "def")}}}

[O] run bash sessions without config files

[Tyler Smith]

Hi,

I use shell-mode a lot, and have a very complex prompt, coloured with
escape codes and lots of bells and whistles. This appears to confuse
org-babel when I'm running code blocks in a session, similar to what's
described here:

https://emacs.stackexchange.com/questions/19735/emacs-freezes-with-any-org-babel-snippet-using-session

Is it possible to configure org-babel to ignore any customization files,
such as .emacs.d/init_bash.el and .bashrc?

As a workaround, I redefine PS1 and PS2 at the top of my org buffer,
which fixes the problem temporarily. I'd like a permanent fix if
possible.

Best,

Tyler

[O] refile workflow -- move to same heading in different file?

[Raymond Zeitler]

How do I customize org to refile from one file to another?  I am baffled
that org-refile is not set up to do this out-of-the-box.

 

versions:

Org mode version 9.0.9 (9.0.9-30-g796a78-elpa @
c:/Users/rayz/AppData/Roaming/RZHOME/.emacs.d/elpa/org-20170703/)

GNU Emacs 25.2.1 (x86_64-w64-mingw32) of 2017-04-24

Windows 7 SP1

user is a member of the local administrator group

 

Details.

C-c C-w cannot seem to recognize any of my agenda files, even though
org-refile-targets is set to (in custom-set-variables):

(org-refile-targets (quote ((org-agenda-files :regexp . "Tasks"

 

Suppose org-agenda-files contains "~/proj1.org" "~/proj2.org" "~/proj3.org"
"~/todo.org".

 

My expectation is that when I press C-c C-w with point on a subheading of
Tasks in todo.org, I can specify, say proj1.org and get the subheading moved
to proj1.org under Tasks.  However, org-refile responds [No Match], even if
I provide the file as ~/proj1.org.  And Emacs is visiting proj1.org in
another buffer.

 

So I now do this manually:

 

Visit todo.org

For Each subheading of Tasks related to proj1.

Place point at the start of subheading

Invoke set-mark-command at end of subheading

; and BTW this is very tricky business, I guess due to narrowing

kill

switch buffer to proj1.org

place point as close to column 1 under the Tasks line

; again very tricky business

yank

switch buffer back to todo.org

Next

 

(Sorry for posting pseudocode that resembles Vi$ual Ba$ic!  The org-babel
question for *that* is in queue.)

Leslie helped here by mentioning vmin/vmax which is that obvious
that I do feel embarrassed now ;-)

#+TBLFM: 
@2$1=vmin(remote(myvalues,@2$1..@>$1))::@2$2=vmax(remote(myvalues,@2$1..@>$1))::@2$3=vmean(remote(myvalues,@2$1..@>$1))::@2$4=remote(myvalues,@2$1)::@2$5=remote(myvalues,@>$1)

However, let's make this thread a valuable one by adding a question:
how does somebody find such things? Is there a source of information
where I could find calc methods by "apropos" method together with
elisp methods?

"M-h a minimum" returns only calc-find-minimum which is hardly of
any help in this case. "apropos-documentation" returns more results
but still lacks "vmin".

What is your method of choice to find answers to those kind of
questions? At least my internet search engine of choice did not help
me in the first place.

[O] exporting org to latex, execute matlab before exporting

[Uwe Brauer]

Hello

Take the following example

* Test section

This is a test
#+begin_src matlab :results output latex :exports results
X=[1,2,3,4,5,6,7];
p=[1/7 1/7 1/7 1/7 1/7 1/7 1/7];
E=X*p';
x2=X.*X;
E2=x2*p';
V=E2-E^2;
disp('\begin{align}')
fprintf('E[X]&=%g \n', E)
fprintf('E^2[X]&=%g\n', E2)
fprintf('V[X]&=%g\n', V)
disp('\end{align}')
#+end_src

Executing the src block leads

#+RESULTS:
#+BEGIN_EXPORT latex
\begin{align}
E[X]&=4\\ 
E^2[X]&=20\\
V[X]&=4
\end{align}
#+END_EXPORT

Which is what I want. When I convert the org file to latex I am again
asked to execute the src block, which I don't want since it is already
executed. How can I avoid this question, without deleting the src block.
This is important if I have a lot of blocks which I already have
executed, and want to export the file without denying is executing every
time I am asked.

Thanks

[O] problem running certain matlab code

[Uwe Brauer]

Hello

Using GNU emacs 26 and the latest orgmode (git), I have problem
executing the followting matlab code
clear all
C =[   7 ,  8 ,  9 , 10 ]
latexarray(C,'format','%3.3f')

I can execute the matlab code in a matlab shell or
in an emacs matlab shell as provided by by matlab.el.
Latexarray is a 3rd party m file found in the matlab website.

But when I run the code in 

#+begin_src matlab :results output latex :exports results
clear all
C =[   7 ,  8 ,  9 , 10 ]
latexarray(C,'format','%3.3f')
#+end_src

I obtain 
#+RESULTS:
#+BEGIN_EXPORT latex

C =

 7 8 910

Warning: This implementation of uiputfile has been deprecated and is no longer
supported.
> In uitools/private/uiputfile_deprecated at 105

??? Error using ==> fprintf
Invalid file identifier.  Use fopen to generate a valid file identifier.

Error in ==> latexarray at 144
fprintf(fid,'%s\n',['\[\begin{array}{',col,'}']);


#+END_EXPORT


What shall I do? I don't understand that orgmode is nitpicking here
while matlab is not.

Thanks

Re: [O] Slow usage of capture templates

[Adam Porter]

This isn't much help, but the best suggestion I have is to try the
non-Cygwin, native Windows build.  I use the Cygwin build myself, but it
is inherently slow compared to Linux builds for some reason.  It takes
probably 10-20 times as long to startup, and everything I do it in it is
slow compared to in Linux.  Maybe the native Windows build will perform
better.

[O] [feature-request] make org-quote-csv-field customizable

[Thomas von Dein]

Hello,

currently when exporting a table to CSV, fields are quoted automatically
if they contain a comma or a quote character. The regexp for this
determination is hard-coded in 'org-quote-csv-field.

This is good for most use cases. However, if you want to import such a
CSV with MS Excel then some unquoted fields will be automatically
converted by Excel into another format.

An example is a field containing 192.168.10.233. 'org-quote-csv-field
doesn't quote it, but Excel - for reasons I cannot fathom - considers
this a number (it doesn't do this when the last octet is below 233
though) and converts it to 19216810233 - which is wrong.

I wrote the following code to circumvent this Excel bug:

(defun tvd-org-quote-csv-field (s)
  "Quote every field and precede it with = to disable excel automatisms."
  (if (string-match "." s)
  (concat "=\"" (mapconcat 'identity
   (split-string s "\"") "\"\"") "\"")
s))

(defun table-to-excel ()
  "export current org table to CSV format suitable for MS Excel."
  (interactive)
  ;; quote everything, map temporarily 'org-quote-csv-field
  ;; to my version
  (cl-letf (((symbol-function 'org-quote-csv-field)
 #'tvd-org-quote-csv-field))
   (org-table-export "/tmp/ex.csv" "orgtbl-to-csv")))

To make this customizable, it would be good to have a variable which
contains the regex to determine what to quote. A parameter to
org-table-export would be an even better solution.


best regards, and thanks for this great module!
Tom

Re: [O] Slow usage of capture templates

[Johan Ekh]

Hi again,
I googled and found this.

(setq
  x-select-enable-clipboard nil
  x-select-enable-primary t)

It improves the situation but capture is still painfully slow.

Any ideas? / Johan

Not really an answer to your request, but, OOC, is there any reason to
move "org-notemuch.el" within "lisp/"?

Hi, thanks,
but I have 25.2.1 so that will not solve it for me. I'm using several
platforms, including Linux, Windows and Cygwin. Only seen this problem n
Cygwin, which of course is the platform I need to use at work...

I also encountered this problem (even though I do not use Windows). It
disappeared when I switched to Emacs 25.2.

Re: [O] Slow usage of capture templates

[Johan Ekh]

Hi again, I tried with elp-instrument-package, see the results below. Seems
like function "org-get-x-clipboard" is taking a long time. CPU usage is
100% for the process "emacs-X11" during this time.

Does anyone have a clue what I should do?
