Org-eval-light enables the execution of source code embedded in org-mode files.
2. How to use it
2.1. Quick Example
As a quick demonstration of use of
org-eval-light first load it as
described below. Then place a
#+begin_src block like that below in
an org-file on your system. Place the cursor inside of the block
(in this case on the same line as the word
date) and press
org-eval-light-current-snippet. This will run
date command in your shell, and will place the output into your
org file after the block. In the case of short output like below,
org-eval-light will use the consise
: style comments, but larger
output (the cutoff default to 10 lines, but can be changed by setting
org-eval-light-example-size-cutoff variable) will be placed in
an example block.
#+begin_src shell date #+end_src
2.2. Loading it (No surprises here)
The easiest way is by
M-x customize-apropos org-modules
Check the line for eval-light. This will cause it to be loaded every time you start org-mode.
You'll still have to load it manually the first time.
Of course, you can also just try it out by loading it manually.
If you prefer to manually customize your emacs then make sure that the
path to org's contrib directory is in your load-path and add the
following to your
2.3. Adding new source-code types
org-eval-light is extensible. If you would like to add a new type
of source code to
org-eval-light you may do so by adding the name of
your new lang (let say
new_lang) to the
org-eval-light-interpreters variable. You will then need to add a
new conditional statement to the
(note: you should only try this if you are willing to get your hands
dirty with some elisp).
If you add a new code type, and get it working please share your changes with the mailing list.
