|
||||
|
||||
;;; Commentary:
|
||||
|
||||
;; This is a major mode for editing files in the YAML data
|
||||
;; serialization format. 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.
|
||||

||||
