Re: [O] double underlines and external references

[John Kitchin]

I see, if it is just export you can still use a link with custom exporters
for internal and external recipes. eg: [[irec: some recipe label]] might
export to \uline{some recipe label} and [[erec:some other recipe]] might
export to \uuline{some other recipe}, and you would use the ulem latex
package to get those commands.

The colors I was referring to were for your benefit in org-mode to make it
easy to see which kind of link it is.

Another alternative is a macro:

#+MACRO: irec  \uline{$1}
#+MACRO: erec  \uuline{$1}
#+LATEX_HEADER: \usepackage{ulem}
{{{irec(some label)}}} and {{{erec(some other label)}}}

This exports to: \uline{some label} and \uuline{some other label}

[O] Can export the files with bibliography only to LaTeX

[Melleus]

I used to think that I can export from org to bunch of different
formats. But all of a sudden when I need this feature I see that I can
export only to LaTeX. But when I try exporting to other format I get

Wrong type argument: stringp, nil   error message.

When there's no bibtex references or exporting to LaTeX everything just
works.

How can I troubleshoot the situation and possibly find the clue? I
couldn't find any documentation on the exporting references issues on
Worg unfortunately.

My environment: Gentoo with stable keyword, Emacs 25.3.1, Org 9.1.4.

Thanks ahead of time.

Thanks for replying John.

I don't think I was quite as explicit as I should've been. I'm exporting
my org-mode documents into latex ones, which are then building a PDF,
which can then be printed in black and white (with no other colours
being allowed), with the ultimate aim of it being professionally printed
as books.

Hence my need for both, double and single line, underlines.

But I'm also open to any other way of finding some other way of showing
the different links, but I can only use either black or white colours.

Thanks
Sharon.

​C-h k shows the documentation for a key binding in a help buffer rather
than just a laid out summary of all the keys in a particular hydra map.
C-h k is important to know the details of what individual keys do, so
hydra needs a way of integrating with standard key documentation lookup
capabilities if it gets integrated with core Emacs, which I would like to
see.

Personally, I also think the red, blue, etc. color notation should change to
something more descriptive of what they do and then the particular colors
associated could be customized to suit any particular visual theme.

But now this one suffers from other problems:
- `C-h k` does not let me directly find the binding of `C-c g`.
- A `C-c a` binding in a lower keymap is now made unavailable.
- A `C-c a` binding in a higher keymap now makes this hydra unavailable.

I want it all.  Don't get me wrong: I fully understand that hydra.el
works within the constraints of what Emacs provides and so it has to
choose between style 1 or style 2, but if we're talking about
integrating this into Emacs, then we should take the opportunity to lift
those restrictions.

As I mentioned in a recent response to Stefan in this thread, I did a poor
job with that problem statement.. I don't want to *just* show the available
bindings.

That's correct. It's up to the package author as to how much of hydra
features they want to pack into their package's hydras. hydra is not *just*
for showing available keys and/or *just* for chaining many single letter
commands. It's much more, in a good way.

Well, that's correct ..

than what I understand you want.

Though I now think I did a very bad job at constructing that problem
statement. But I know for sure that hydra.el fits the bill perfectly (I've
been using it ever since Oleh released it).

Integrating hydra into emacs with help package developers do these:
- Create interfaces for transitional keymaps
- The bindings could be sticky or not (can be configured in hydra)
- Allow customizing the descriptions of the bindings (@JWiegley as you
later suggest which-key, which-key does not allow that.. well it does.. but
the user will need to tweak the description, etc.. I see which-end more as
a tool only for the end-user. hydra can be used both by package developers
and end users).
- Pick and choose which bindings to "show" in that interface.. you don't
have to show all. The package developer may choose to have duplicate
bindings for some function in that keymap, but prefer to show only the
preferred binding in the hydra popup (cannot do that in which-key.. it
shows *everything*).

That's because you used Style 1 (as explained in this hydra Wiki:
https://github.com/abo-abo/hydra/wiki/Binding-Styles). Use the Style 2 to
take care of the issue you stated:

(defhydra hydra-zoom ()
  "zoom"
  ("g" text-scale-increase "in")
  ("l" text-scale-decrease "out"))

(global-set-key (kbd "C-c") 'hydra-zoom/body)

In Style 1, you allow the hydra to share the "keymap space" with other
bindings not related to that hydra.

In Style 2, the hydra takes over the whole "keymap space". In above Style 2
example, the "C-c" space is completely ruled by the hydra-zoom hydra.

No. It does everything that I need to do. But of course it has a lot of
features, which might be suitable for different applications. See keys like
:pre, :post and more described in
https://github.com/abo-abo/hydra/wiki/internals.

I can see something like this begin added to smerge.el if and when hydra.el
gets merged to the core (See the use of :pre and :post):

(defhydra hydra-smerge (:color pink

:pre (smerge-mode 1)

Re: [O] double underlines and external references

You could just use regular links for this. You could setup a face function
that changes the color depending on it being internal or external, or you
could make separate links for them. See
http://kitchingroup.cheme.cmu.edu/blog/2016/11/04/New-link-features-in-org-9/

[O] double underlines and external references

[Sharon Kimble]

For my current series of books that I'm writing in org-mode which is
being exported to latex, I need to differentiate between recipes in the
current working file, and to recipes in an external file. This is in a
series of books all containing recipes. So what I'm looking for is the
ability to use a single underline for internal, and a double underline
for external. I can do a single underline easily in org-mode, but I'm
having problems with a double underline.

But is it the best method, using single and double underlines? Can
anyone suggest some other ways of doing it, please? Like, for instance,
can I have a reference to a particular section in another file?

[O] Feature request: Add window-setup options to capture and note taking

Hi,

I don't like that org fiddles with my window setup, even
if it's only temporary.

I can set `org-agenda-window-setup` and `org-src-window-setup`
to change the behavior for the babel and agenda window but for other
functions it seems to be hard coded.

I would be interested especialy in the note taking (`org-add-log-note`),
org capture (`org-capture-place-template`) and the first view
when you call org-agenda (`org-agenda-get-restriction-and-command`).

Thanks,

I've had a look at the code, which seems to be in ox-latex, and I cannot
understand why beamer export acts differently to LaTeX.  Something to do
with the :tag property but I really don't understand it.  Maybe somebody
else can have a look (org-latex-item in ox-latex.el, approximately line
2182 and following).

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 ;).
