Starter Kit Org

Configuration for the eminently useful Org Mode.

Org-mode is for keeping notes, maintaining ToDo lists, doing project planning, and authoring with a fast and effective plain-text system. Org Mode can be used as a very simple folding outliner or as a complex GTD system or tool for reproducible research and literate programming.

For more information on org-mode check out worg, a large Org-mode wiki which is also implemented using Org-mode and git.

Org-Mode Hook – Keybindings

(add-hook 'org-mode-hook
          (lambda ()
            (local-set-key "\M-\C-n" 'outline-next-visible-heading)
            (local-set-key "\M-\C-p" 'outline-previous-visible-heading)
            (local-set-key "\M-\C-u" 'outline-up-heading)
            ;; table
            (local-set-key "\M-\C-w" 'org-table-copy-region)
            (local-set-key "\M-\C-y" 'org-table-paste-rectangle)
            (local-set-key "\M-\C-l" 'org-table-sort-lines)
            ;; display images
            (local-set-key "\M-I" 'org-toggle-iimage-in-org)))

Speed keys

Speed commands enable single-letter commands in Org-mode files when the point is at the beginning of a headline, or at the beginning of a code block.

See the `=org-speed-commands-default=' variable for a list of the keys and commands enabled at the beginning of headlines. All code blocks are available at the beginning of a code block, the following key sequence C-c C-v h (bound to `=org-babel-describe-bindings=') will display a list of the code blocks commands and their related keys.

(setq org-use-speed-commands t)

Code blocks

This activates a number of widely used languages, you are encouraged to activate more languages using the customize interface for the `=org-babel-load-languages=' variable, or with an elisp form like the one below. The customize interface of `=org-babel-load-languages=' contains an up to date list of the currently supported languages.

(org-babel-do-load-languages
 'org-babel-load-languages
 '((emacs-lisp . t)
   (sh . t)))

You are encouraged to add the following to your personal configuration although it is not added by default as a security precaution.

(setq org-confirm-babel-evaluate nil)

Code block fontification

The following displays the contents of code blocks in Org-mode files using the major-mode of the code. It also changes the behavior of TAB to as if it were used in the appropriate major mode. This means that reading and editing code form inside of your Org-mode files is much more like reading and editing of code using its major mode.

(setq org-src-fontify-natively t)
(setq org-src-tab-acts-natively t)

The Library of Babel

The library of babel contains makes many useful functions available for use by code blocks in any emacs file. See the actual library-of-babel.org (located in the Org-mode contrib/babel directory) file for information on the functions, and see worg:library-of-babel for more usage information.

Code blocks can be loaded into the library of babel from any Org-mode file using the `org-babel-lob-ingest' function.
