[O] Bug: Evil's evil-ex-substitute does not expand headlines as necessary. [8.2.10 (release_8.2.10 @ /usr/share/emacs/25.2/lisp/org/)]

[Gary Cheng]

Emacs  : GNU Emacs 25.2.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.22.16)
 of 2017-07-15
Package: Org-mode version 8.2.10 (release_8.2.10 @
/usr/share/emacs/25.2/lisp/org/)




When using evil's substitute (:%s/string1/string2/c) in an org file, if the
string that is to be substituted is hidden under a headline, the cursor
will go to the end of the line of the headline of the string, as opposed to
expanding the headline automatically and putting the cursor on the string
the way evil's find (/) does. It should match evil's find behavior which is
more intuitive and useful by doing the same thing.

Thanks to both of you: It used to work, then it didn't, only a
few days ago I realised there was a difference between M-RETURN
and M-RET but thought of this as a configuration error and now it
simply works again!

You are creating a file that Org is supposed to fill with the output
from your script.  Your script doesn't produce output, but instead
writes to the same file.  When the script returns, Org dutifully
truncates the file to nothing.

This is because L is not a valid list. In particular, it contains two

[O] org-list-to-subtree strange behaviour

[Robert Klein]

Hi,

I'm trying to use org-list-to-subtree in a publishing projects
sitemap-function.

However, the org-list-to-subtree function only returns the first entry.

That is, when I run

(org-list-to-subtree  l '(:istart "** "))

after setting the variable l (see below, I didn't want the
120+ lines interrupting this text) , I get this result:


"**   [[file: openbsd-pxe.org][OpenBSD deployment via PXE]]
#+begin_article-info
#+BEGIN_date
2017-09-10
#+END_date
#+BEGIN_tags
OpenBSD, PXE, Installation, Deployment
#+END_tags
#+begin_article-info

"

where I expected all nine entries in the list.


It works for simple lists, e.g.

  (setq l '(unordered
("alpha")
("beta")
("gamma")))

results in

"** alpha
** beta
** gamma"

which is about what I expect.

Any Ideas?


Thank you very much!

Best regards
Robert

I may also want a evaluation that submits the code to online judge and

This seems to be another topic. One that Babel is not concerned about. 
Are you trying to set up a work-flow where students submit their 
solutions to a teacher who is the "judge"? Isn't email between students

> Does customizing `org-show-context-detail' fix your issues? 

Hi,

Thanks, it would have taken me quite some time to find that.

The default was "ancestors." Changing it to "local" works well for me.

I'm puzzled because, for years, it was behaving as I wanted. I believe the 
former behavior was "local" -- I have a slight shred of a doubt only because, 
when things are working as you expect, you take the behavior for granted and 
don't pay attention to all of the details.

I'm 100% certain that I was seeing at least the next sibling when jumping to an 
item from the agenda. If I had been seeing the "ancestors" behavior all along, 
I would have asked this question years ago and set it explicitly.

So, again, somehow this morning, one minute I had good behavior, and literally 
five minutes later (no restart, no software update, no quit/relaunch Emacs), it 
was a different, inconvenient behavior. I don't understand how that could 
happen.

Thanks for the tip, though. The behavior now is much better.

Re: [O] evaluate cpp snippet in org babel with default includes and customized entry point

You may further hide the includes with a property drawer. An additional 
benefit is that those includes are shared among all babels under the 
same section.

  :includes:

#+BEGIN_SRC C++

* Array

** Two Sum

Given an array of integers, return indices of the two numbers such that they 
add up to a specific target.

You may assume that each input would have exactly one solution, and you may not 
use the same element twice.

Example:
Given nums = [2, 7, 11, 15], target = 9,

Because nums[0] + nums[1] = 2 + 7 = 9,
return [0, 1].


#+BEGIN_SRC cpp
class Solution {
public:
vector twoSum(vector& nums, int target) {

}
};
#+END_SRC

#+RESULTS:


I need to add default headers and pass arguments to the entry class.
