[Babel] Macro for begin_src?

[Babel] Macro for begin_src?

[Nathan Neff]

[-- Attachment #1.1: Type: text/plain, Size: 440 bytes --]

I've been converting my init.el file to org-babel, and am getting tired of
copying/pasting or typing the begin_src and end_src blocks.

Example:
#+begin_src emacs-lisp :results silent
#+end_src

As an Emacs n00b, I'd like to know if anyone here has defined some kind of
macro / shortcut to define an org-babel block.

I'd like a shortcut/macro that I could put into my config files, and put
into my git repo.

Thanks for any input,

--Nate

*Sigh* I Googled around for about 15 minutes, then posted the question to
the mailing list. (I swear!)

Then, I stumbled upon Brent's Yasnippets when researching something totally
different.

http://doc.norang.ca/org-mode.html#Yasnippets

If anyone else has a different macro set up, I'm still interested in hearing
your solutions.

Thanks,

+1

it might be nice to have a worg page on snippets for org-mode?  I'm
happy to contribute a few.  The ones I use the most are these two:

block:
--8<---------------cut here---------------start------------->8---
#name : #+begin_...#+end_
# --
#+begin_$1 $2
$0
#+end_$1
--8<---------------cut here---------------end--------------->8---

and

figure:
--8<---------------cut here---------------start------------->8---
#name : figure
# --
#+attr_latex: width=$1\textwidth
[[file:$2.pdf]]
$0
--8<---------------cut here---------------end--------------->8---

What do you guys use for ditaa diagrams?

Just copy/paste?  Seems like it'd be a bit tedious to draw those boxes.

Shelagh,

artist-mode has a full set of key bindings.  I never use the mouse
(for anything at all, if I can help it, due to RSI issues) and
artist-mode is perfectly usable nonetheless!  Type "C-h m" in
artist-mode to see all the key bindings.

HTH,
eric

I am aware of the keybindings, though I tend to use the mouse myself, but 
I have never been able to get artist-mode running properly in tty. If you 
have, I would be interested to know if you had to tweak anything to get 
it to work or whether it is the usual "my set-up is screwy and I don't 
know why" syndrome.

The key bindings don't work well for me in regular emacs in X either.

GNU Emacs 22.2.1 (i486-pc-linux-gnu, GTK+ Version 2.12.11) of 2008-11-09
on raven, modified by Debian

Marking regions seems to lose the mark when I move around trying to draw
rectangles.  Using the mouse is much easier for this.

I do find artist-mode to be quite finicky (maybe it is less so using
the mouse but I've not really tried it that way) so I have a feeling
that your problems are due to artist-mode itself.  I've not tweaked
anything however.  In any case, I use it less and less, doing most
drawing with either graphviz (dot et al.) and tikz (in latex).

Sorry I can't be more helpful.

M-x customize-variable RET org-edit-fixed-width-region-mode
and choose `picture-mode':

  `C-c >'  move right after each keypress
  `C-c <'  move left after each keypress
  `C-c ^'  move up after each keypress
  `C-c .'  move down after each keypress


Picture-mode is always active here if I do `M-x artist-mode'. I'm not
sure why. It even becomes the major mode. Might be how things work in
emacs24 as I couldn't find anything in my setup.

Sure. Or having them somewhere in the git directories...

Better use \linewidth instead of \textwidth. You will avoid bad surprises.

They are generally equivalent, but \linewidth is more often the real width to
consider: it is correctly adapted in column environments, itemized lists and
quotes, to cite a few.

Interesting.  I've always used textwidth and have never run into
problems: it does adapt to column environments and I've never really
used this within lists or quotes I guess.  Good to know and I'll try
to re-train my fingers to type linewidth instead!  (and I've already
updated my snippet...)

+1 for git directories.

That way users who keep their Emacs config in git repos can add the
snippets as a submodule, and I can include the submodule in the literate
emacs-starter-kit [1].

Is there any progress on that? I just started with yasnippet and think they
are quite handy.

I got the yasnipet expansion working through your Starter Kit (
http://eschulte.github.com/emacs-starter-kit/starter-kit-org.html) and I
realised that you have org-toggle-iimage-in-org in it - as far as I know,
this does not exist any more in the newer versions of org (but it does not
cause an error).

Yes,

The snippets used by the starter kit are available in their own git
repository at http://github.com/eschulte/yasnippet-org-mode

also, any suggestions or contributions are welcome

The usual github lossage :-) The http interface for people to look at
the repo is the above path.  However the git repo has a .git on the end.
Use the path you quoted with a browser and find the git URL.

There are quite a few other options. IMO, installing yasnippet is
overkill if you are only using it for comment blocks in org-mode.

1. The first and simplest option is built into org-mode. Simply type:

<s [TAB] or [M-TAB]

This will automatically expand to:

--8<---------------cut here---------------start------------->8---
#+begin_src 

#+end_src
--8<---------------cut here---------------end--------------->8---

For a full list of completions, type "C-h v
org-structure-template-alist".

2. The second option is to save the text to a register:

(set-register ?b "#+begin_src\n\n#+end_src")

Then type C-x r i b to insert the source block.

(info "(emacs) Registers")

3. You can use abbrev mode for dynamic expansion:

 - Activate the abbrev minor-mode in org-mode:

   + M-x abbrev-mode

   + permanently: (add-hook 'org-mode-hook (lambda () (abbrev-mode 1)))

 - In org-mode, type something like "sbp" for a perl source block.

 - Immediately after "sbp" type C-x a i l.

 - Enter the expansion: #+begin_src perl[C-q C-j][C-q C-j]#+end_src

   + Note: the C-q C-j creates a new line in the minibuffer

 - Now, whenever, you type sbp[Space, RET, TAB, etc.] in an org-mode
   buffer, the src block will magically appear.

 - If you want more complex completion (like yasnippet) you can combine
   abbrev mode with skeletons.

   See: 
    - (info "(emacs) Abbrevs") and
    - http://www.emacswiki.org/emacs/SkeletonMode

Thanks Matt for this.  I'd forgotten about the built-in definitions.
These do make many of my yasnippets superfluous.

Good question!  One case I would still use yasnippets for is more
complex constructions.  For instance, I use tikz a lot for creating
drawings for teaching.  For a given course, many of these drawings are
similar.  One snippet I have is:

--8<---------------cut here---------------start------------->8---
#name : tikz
# --
#+begin_latex 
\tikzstyle{unit}=[rectangle, draw=blue!80!black, fill=black!5!white]
\tikzstyle{stream}=[rectangle, draw=white, fill=yellow!50!white]
\begin{tikzpicture}[node distance=2cm]
  \node[stream] (feed) {Feed};
  \node[unit] (reactor) [right of=feed] {Reactor} edge [<-] (feed);
  \node[unit] (separator) [right of=reactor] {Separation} edge [<-] (reactor);
$0
\end{tikzpicture}
#+end_latex
--8<---------------cut here---------------end--------------->8---

Before Carsten implemented the beamer option in org-mode, I also had a
snippet for setting up columns with blocks in org-mode for my custom
beamer setup I used to have.

I guess, for Nate's original application (converting existing code to
src blocks), what might have been most useful is something to enclose a
given region in a source block. Can anyone show how to do that with
yasnippet (or anything else)? Or is it best to make a custom function
for a task like this, e.g.

  (defun dan/enclose-region-in-src-block ()
    (interactive)
    (let* ((beg (if (region-active-p) (region-beginning) (point)))
           (end (if (region-active-p) (region-end) (point))))
      (goto-char end)
      (unless (eq (char-before) ?\n) (insert "\n"))
      (insert "#+end_src\n")
      (goto-char beg)
      (beginning-of-line)
      (insert "#+begin_src \n")
      (backward-char)))

I don't have a ready-to-use snippet, but this is what you need:

and you can also insert the value of yas/selected-text directly into
the snippet anywhere you want.  e.g.

--8<---------------cut here---------------start------------->8---
#name : testing yasnippets for org-mode
# --
#+BEGIN_LaTeX
`yas/selected-text`
$0
#+END_LaTeX
--8<---------------cut here---------------end--------------->8---

of course, you can only do this (or the wrap around region approach)
if you invoke the snippet directly using a key binding (e.g. the
default "C-c & C-s" or "M-x yas/insert-snippet") as opposed to tab
expansion on the snippet name (which is more convenient).

Note that you can assign key bindings directly to snippets.

Hi Nate,

By the way, if you are using :results silent for all your blocks, then
you can just enter it once as a buffer property:

#+property: results silent

(and if you want it for a whole subtree but not a whole buffer, then set
a property called :results: with value silent in the root of the
subtree).

I agree with the others about using yasnippets for blocks. I have src
and elisp snippets (although to be honest I still haven't learned the
syntax for defining them and I have trouble stopping them leaving
annoying trailing spaces...ok thanks you made me fix that, although I
still don't know the syntax, something like this then

src:

#+begin_src...#+end_src
# --
#+begin_src ${2:language}
$0
#+end_src

elisp:

#name : #+begin_src...#+end_src
# --
#+begin_src emacs-lisp
$0
#+end_src


)

Thanks!  I'm having trouble triggering the yasnippets using the TAB key, so
I'm just using the GUI menu.

Do you literally type "src" (no quotes), then press Tab?

Yeah, but there's some magic code needed, which is also on Bernt's
page.

  (add-hook 'org-mode-hook
            (lambda ()
              ;; yasnippet
              (make-variable-buffer-local 'yas/trigger-key)
              (setq yas/trigger-key [tab])
              (define-key yas/keymap [tab] 'yas/next-field-group)))

Do you have that?  What do you get if you do C-h k TAB in org? I get

<tab> runs the command yas/expand ...

I'm guessing what you really want there is

(set (make-local-variable 'yas/trigger-key) [tab])

instead of

>               (make-variable-buffer-local 'yas/trigger-key)
>               (setq yas/trigger-key [tab])

The difference is that in the latter case you're making
`yas/trigger-key' be automatically buffer-local for *all* buffers, not
only in the buffer you're setting it (see e.g. the docstring of
`make-variable-buffer-local').

Hmmm.

Do you guys un-map your TAB key so that it doesn't run org-cycle?
My TAB key will correctly trigger yas/insert-snippet in emacs-lisp mode.
However, in org-mode my TAB key is still mapped to org-cycle, even if I add
the org-mode hook using the code above.

Thanks,
--Nate

Hi Nate,

I use a yasnippet for that after learning about them from Eric
