I've made some changes to org-eval and packaged them into a new
org-eval-light.el file. While this reworked version loses some of the
automatic evaluation, and most all of the similarity to Emacs Muse that
the original org-eval tried to maintain, I believe that it represents
(for me at least) a safer and more use-able way of packaging and calling
source code from inside of org-files.
The changes include...
,----[org-eval-light.el]
| ;;; Changes: by Eric Schulte
| ;;
| ;; 1) forms are only executed manually, (allowing for the execution of
| ;; an entire subtree of forms)
| ;; 2) use the org-mode style src blocks, rather than the muse style
| ;; <code></code> blocks
| ;; 3) forms are not replaced by their outputs, but rather the output
| ;; is placed in the buffer immediately following the src block
| ;; commented by `org-eval-light-make-region-example' (when
| ;; evaluated with a prefix argument no output is placed in the
| ;; buffer)
| ;; 4) add defadvice to org-ctrl-c-ctrl-c so that when called inside of
| ;; a source block it will call `org-eval-light-current-snippet'
`----
The amount of new code is minimal, but I think it provides a nice
alternative for source code evaluation, and hopefully takes org-mode one
step closer to being a first-class Experimentation and
Reproducible-Research tool. The code is available here
http://github.com/eschulte/org-contrib/tree/master%2Forg-eval-light.el?raw=true
As a side note, I feel that org-mode should be listed here
http://www.reproducibleresearch.org/tools_and_resources.html
Thanks -- Eric
