将python模式与emacs的org模式相结合

Question

我将ORG模式与LISP模式相结合，以实现LISP代码的Emacs中的美丽代码折叠： LISP-ORGI模式。基本上，我使用';'而不是“*”作为标题角色。为了评论，我只是在“;”之前放一个空间；因此，它不算为标题...

但是，使用Python模式进行同样的事情不起作用...可能是因为Python注释使用的“＃”字符会干扰Org-Mode设置...

有人能够成功地结合功能吗？我知道人们已经将Python模式与大纲模式相结合（关联），但是OUline模式不如org模式...

编辑：让它与 大纲魔术: ：python-magic.el

我用 Hideshow-Org (和一个小介绍）为此，我认为它确实非常好。

这些是一些其他但有用的片段：

(dolist (hook (list 'c-mode-common-hook
            'emacs-lisp-mode-hook
            'java-mode-hook
            'lisp-mode-hook
            'perl-mode-hook
            'sh-mode-hook))
  (add-hook hook 'my-hideshow-hook))

(defun my-hideshow-hook ()
  "thisandthat."
  (interactive)
  (progn (require 'hideshow-org)
     (global-set-key (kbd "C-c h") 'hs-org/minor-mode)
     (hs-org/minor-mode)))

(defadvice goto-line (after expand-after-goto-line activate compile)
  "hideshow-expand affected block when using goto-line in a collapsed buffer"
  (save-excursion
    (hs-show-block)))

好的，我得到了以下大纲 - regexp的概述 - 刻录模式：“ [ t]*＃ | [ t]+（class | def | if | elif | elif | else | while while while while | for | try | extbore | with ）“现在我使用Python语法和评论行作为标题获得代码折叠。
是否可以适应您的代码来使用选项卡来调用“缩进为tab-command”，如果无事可做，请调用'outline'outline-cycle？

python-magic.el：

我认为 outline-magic 已被取代 outshine, ，我不知道上面的代码是否可以使用。但是我能够获得以下代码工作，这是由 瑞安·戴维斯（Ryan Davis）的博客文章:

(defun python-mode-outline-hook ()
  (setq outline-level 'python-outline-level)

  (setq outline-regexp
    (rx (or
         ;; Commented outline heading
         (group
          (* space)  ; 0 or more spaces
          (one-or-more (syntax comment-start))
          (one-or-more space)
          ;; Heading level
          (group (repeat 1 8 "\*"))  ; Outline stars
          (one-or-more space))

         ;; Python keyword heading
         (group
          ;; Heading level
          (group (* space)) ; 0 or more spaces
          bow
          ;; Keywords
          (or "class" "def" "else" "elif" "except" "for" "if" "try" "while")
          eow)))))

(defun python-outline-level ()
  (or
   ;; Commented outline heading
   (and (string-match (rx
               (* space)
               (one-or-more (syntax comment-start))
               (one-or-more space)
               (group (one-or-more "\*"))
               (one-or-more space))
              (match-string 0))
    (- (match-end 0) (match-beginning 0)))

   ;; Python keyword heading, set by number of indentions
   ;; Add 8 (the highest standard outline level) to every Python keyword heading
   (+ 8 (- (match-end 0) (match-beginning 0)))))

(add-hook 'python-mode-hook 'python-mode-outline-hook)

也许有人会发现这有用。我认为这是使编辑和导航代码更加容易的一种了不起的方法。
