Support Vim, Tmux, Emacs with Stow
After moving off of Meta, Dotfiles has a greater responsibility to manage configs. Vim, Tmux, and Emacs are now within Stow's purview.

It was initially developed by Yoshiki +;; Kurihara and many features were added by Marshall Vandegrift. As +;; YAML and Python share the fact that indentation determines +;; structure, this mode provides indentation and indentation command +;; behavior very similar to that of python-mode. + +;;; Installation: + +;; To install, just drop this file into a directory in your +;; `load-path' and (optionally) byte-compile it. To automatically +;; handle files ending in '.yml', add something like: +;; +;; (require 'yaml-mode) +;; (add-to-list 'auto-mode-alist '("\\.yml\\'" . yaml-mode)) +;; +;; to your .emacs file. +;; +;; Unlike python-mode, this mode follows the Emacs convention of not +;; binding the ENTER key to `newline-and-indent'. To get this +;; behavior, add the key definition to `yaml-mode-hook': +;; +;; (add-hook 'yaml-mode-hook +;; '(lambda () +;; (define-key yaml-mode-map "\C-m" 'newline-and-indent))) + +;;; Known Bugs: + +;; YAML is easy to write but complex to parse, and this mode doesn't +;; even really try. Indentation and highlighting will break on +;; abnormally complicated structures. + +;;; Code: + + +;; User definable variables + +;;;###autoload +(defgroup yaml nil + "Support for the YAML serialization format" + :group 'languages + :prefix "yaml-") + +(defcustom yaml-mode-hook nil + "*Hook run by `yaml-mode'." + :type 'hook + :group 'yaml) + +(defcustom yaml-indent-offset 2 + "*Amount of offset per level of indentation." + :type 'integer + :safe 'natnump + :group 'yaml) + +(defcustom yaml-backspace-function 'backward-delete-char-untabify + "*Function called by `yaml-electric-backspace' when deleting backwards. +It will receive one argument, the numeric prefix value." + :type 'function + :group 'yaml) + +(defcustom yaml-block-literal-search-lines 100 + "*Maximum number of lines to search for start of block literals." + :type 'integer + :group 'yaml) + +(defcustom yaml-block-literal-electric-alist + '((?| .
