Have you signed FSF papers? Otherwise, you need to add TINYCHANGE at the

If yes, then it's really worth mentioning this fact in the manual (4.6
Link abbreviations) because ones get the impression that only - and _
are allowed. One of the most strong sides of org is its readability as
raw text and in this case space makes link more readable.

I wanted to avoid `org-link-abbrev-alist' as it is Emacs specific, while
#+INCLUDE: is part of the org-mode standard which should work also on
other platforms (theoretically).

I don't know any of these, but here come some comments about the code.

Nitpick: You can merge the `unless' into the `cond'.

The `run-js' probably needs to be declared at the beginning of the file.

My bad. Spaces are not allowed, because

  #+LINK: linkword URL

would not be parse-able. The manual states

The linkword must be a word, starting with a letter, followed by
letters, numbers, ‘-’, and ‘_’.

but it seems implementation only disallows spaces (for LINK keyword) and
colons (for links).

#+LINK: link word URL

Why should this not be parse-able? Cut #+LINK: from the beginning, URL
(last token) from the end, and the rest will be "link word", even with
(several) spaces in between...

[O] Capture template expansion: feature or bug?

[François Allisson]

Hello everyone,

When one uses the following template expansion,

> %^{prop}p   Prompt the user for a value for property ‘prop’.

it supposes one to supply a non-empty string of characters. If one
simply hits RETURN on a given prompt for property, the capture process
ends with an

> org-capture: Capture abort: (quit)

message. This means that all prompts for properties are mandatory. It
this a feature or a bug?

Of course, if I ask the question, it is because I clearly see use cases
for optional properties prompts (which would leave empty the property in
question): you ask for several information, which you don't always have;
and you don't want the capture process to quit because of that. But may
be there is a better way to achieve this?

Many thanks in advance for your time!

Best,
François

Yes, I even did a clean install:

CURR_DIR=$(pwd)
# make test
make
make doc
make refcard
make config

printf "Only root can do this...\n"
sudo make --directory=${CURR_DIR} install

This is what the installation process said:

= Emacs executable and Installation paths
EMACS   = emacs
DESTDIR = 
ORGCM   = dirall
ORG_MAKE_DOC= info html pdf
lispdir = /usr/share/emacs/site-lisp/org
infodir = /usr/share/info
datadir = /usr/share/emacs/etc/org
testdir = /tmp/tmp-orgtest
= Additional files from contrib/lisp

= Org version
make:  Org mode version 9.1.7 (release_9.1.7-516-gbc7b24.dirty =>
/usr/share/emacs/site-lisp/org)

As there is no real error, I can't produce a backtrace, but I try to
follow the call chain of the uncompiled files - at the moment without
success.

I'm quite desperated, do you have an idea?

[O] [BUG] org-sort-entries errors out when headline is empty

[Sebastian Reuße]

So, I’ve noticed that when sorting a subtree (alphabetically or numerically),
‘org-sort-entries’ will raise an error arising from the call to
‘org-sort-remove-invisible’ (lines 8761 and 8766 in bc7b24d0d).

I’m following up with a test. The error is triggered by the capture group in
‘org-complex-heading-regexp’ returning nil, which is then passed on to
‘org-sort-remove-invisible’, which expects a string and chokes on the nil.

As for a fix, the quick fix would be guarding against this case in
‘org-sort-remove-invisible’, but that seemed a bit meh since sanitation should
probably be handled higher up.

An alternative is to guard inside ‘org-sort-entries’. I’m following up with an
implementation of this.

I was also wondering if it might make sense to tweak
‘org-complex-heading-regexp’ so that the respective capture group captures an
empty string. This could be achieved by making the title group greedy again
(reverting 9d334897e). Whether we want this probably depends on the motivation
for 9d334897e. However, doing so would be more consistent with the org-elements
API, which does assign a tag list to the title property when the heading is
otherwise empty.

Any thoughts?

Kind regards,
SR

It looks like ob-shell sets up sessions just by calling `shell`, which means 
all the user's customizations for shell-mode are automatically applied. This 
includes setting the prompt (e.g., from .emacs.d/init_bash.sh), as well as the 
value of `comint-prompt-regexp`.

I can't see any straightforward way to modify ob-shell sessions without also 
changing regular shell-mode. So I wonder if the easiest way to address this 
would be to create a new mode derived from shell-mode, ('ob-shell-mode')? That 
would give us a way to modify the prompt code inside babel without interfering 
with shell-mode.

If that sounds sensible I can put together a patch for ob-shell.el. Let me know 
what you think.

Best,

Tyler

[O] [PATCH 2/2] Guard against empty headings when sorting

[Sebastian Reuße]

* org.el (org-sort-entries): Guard against empty headings when sorting
alphabetically, numerically.

Due to how ‘org-complex-heading-regexp’ is defined, the title capture group
currently returns nil in empty headings, which we don’t want to pass on to
‘org-sort-remove-invisible’.

Re: [O] Structured links to headings with endless depth

This is a tricky problem to generally solve. I think this does it
approximately well enough. It is lightly tested and works by exactly
matching headlines at subsequent levels. It will be problematic if you have
headlines with : in them, and it assumes there is a level 1 headline to
start in.

Re: [O] org mode error "pdf wasn't produced"

[John Hendy]

Dejere,


Org-mode is not able to find your latex installation. That's the
problem, just as it says: it's trying to run the compilation command,
`pdflatex` and it can find no such thing.

Either it's not installed, or it's not in your path. The more details
you can provide, the better. For starters 1) what latex variant is
installed and 2) is it in your path (and how do you know)?

John

Hi,

The dollar character looks strange. What syntax is that?


I agree that it is strange. I mentioned it (and its strangeness) in the 
cover-letter. The documentation of org-sbe describes it as well.

Why `eval'? Why not simply (org-sbe identity (x ...)) ?


Ah, I guess that's another "funny" thing about org-sbe that I forgot to 
mention. It is a macro, but it does some things that are rather 
non-macro-y. In this case, eval is required, otherwise it will attempt 
to parse the Org document during Lisp *compilation*, and you will see:


Eager macro-expansion failure: (error "Reference ‘identity’ not found in 
this buffer")
Eager macro-expansion failure: (error "Reference ‘identity’ not found in

Re: [O] org mode error "pdf wasn't produced"

That means emacs is not finding pdflatex on your path.

A little more information might help.

1. In a terminal, if you type:

> which pdflatex

to you get anything?

2. How do you launch emacs? If you are launching it from some icon, you
might not be getting the same path environment as from a shell.
