I recently started looking into Autotools, to make it easier to run my code on multiple platforms.

Naturally you can use cmake or scons or waf or ninja or tup, all of which are interesting in there own respect. But none of them has seen the amount of testing which went into autotools, and none of them have the mount of tweaks needed to support about every system under the sun. And I recently found pyconfigure which allows using autotools with python and offers detection of library features.

@marjoleink asked on identi.ca¹, if it is possible to use emacs org-mode for showing scaled screenshots inline while writing. Since I thought I’d enjoy some hacking, I decided to take the challenge.

I wrote some recipes for creating the kinds of slides I need with emacs org-mode export to beamer latex.

Update: Read ox-beamer to see how to adapt this to work with the new export engine in org-mode 0.8.

The recipes as PDF (21 slides, 247 KiB)

The org-mode sources (12.2 KiB)

Below is an html export of the org-mode file. Naturally it does not look as impressive as the real slides, but it captures all the sources, so I think it has some value.

Note: To be able to use the simple block-creation commands, you need to add #+startup: beamer to the header of your file or explicitely activate org-beamer with M-x org-beamer-mode.

PS: I hereby allow use of these slides under any of the licenses used by worg and/or the emacs wiki.

If you want to use the literate programming features in emacs org-mode, you can try this minimal example to get started: Activate org-babel-tangle, then put this into the file noweb-test.org:

Minimal example for noweb in org-mode

* Assign 

First we assign abc:

#+begin_src python :noweb-ref assign_abc
abc = "abc"
#+end_src

* Use

Then we use it in a function:

#+begin_src python :noweb tangle :tangle noweb-test.py
def x():
  <<assign_abc>>
  return abc

print(x())
#+end_src

noweb-test.org

Update (2013-01-23): The new org-mode removed (org-make-link), so I replaced it with (concat) and uploaded a new example-file: org-custom-link-completion.el.
Happy Hacking!

I recently set up custom completion for two of my custom link types in Emacs org-mode. When I wrote on identi.ca about that, Greg Tucker-Kellog said that he’d like to see that. So I decided, I’d publish my code.

Kanban for emacs org-mode.

Update (2013-04-13): Kanban.el now lives in its own repository: on bitbucket and on a statically served http-repo (to be independent from unfree software).

Update (2013-04-10): Thanks to Han Duply, kanban links now work for entries from other files. And I uploaded kanban.el on marmalade.

Some time ago I learned about kanban, and the obvious next step was: “I want to have a kanban board from org-mode”. I searched for it, but did not find any. Not wanting to give up on the idea, I implemented my own :)

The result are two functions: kanban-todo and kanban-zero.

“Screenshot” :)

Ich bin gerade auf das Paper hier gestoßen:

“A Multi-Language Computing Environment for Literate Programming and Reproducible Research” (PDF)

Es beschreibt schön, was mit emacs org-mode möglich ist. Dazu gehören so spannende Punkte wie im Dokument mitgelieferter Quellcode, dessen Ergebnisse automatisch eingebunden werden, so dass die Dokumente aktuell bleiben können.
