将Python模式与Emacs中的Org模式相结合

将Python模式与Emacs中的Org模式相结合

10

我将org-mode和lisp-mode结合，以实现在emacs中针对lisp代码的美丽代码折叠: lisp-orgi-mode。基本上，我使用';'而不是'*'作为标题字符。对于注释，我只需在';'前面加一个空格，使其成为' ;'，这样它就不会被视为标题...

然而，用python-mode做同样的事情却行不通... 可能是因为Python注释使用的'#'字符与org-mode设置产生了冲突...

有人能够成功地将这些功能组合起来吗？我知道有人已经将python-mode与outline-mode (链接)组合起来，但ouline-mode并不像org-mode那样好用...

编辑：通过outline-magic，我成功地使其与python-magic.el良好地配合。

python-magic.el :

; 需要CarstenDominik在此处找到的outline-magic.el：http://www.astro.uva.nl/~dominik/Tools/outline-magic.el
; Nikwin稍微修改了这里的代码：https://dev59.com/UnNA5IYBdhLWcg3wH6AW#1085551
(add-hook 'outline-minor-mode-hook 
           (lambda () 
             (require 'outline-magic)
))
(add-hook 'python-mode-hook 'my-python-outline-hook)
(defun py-outline-level ()
  (let (buffer-invisibility-spec)
    (save-excursion
      (skip-chars-forward "    ")
      (current-column))))
(defun my-python-outline-hook ()
  (setq outline-regexp "[ \t]*# \\|[ \t]+\\(class\\|def\\|if\\|elif\\|else\\|while\\|for\\|try\\|except\\|with\\) ")
  (setq outline-level 'py-outline-level)
(outline-minor-mode t)
  (hide-body)
  (show-paren-mode 1)
  (define-key python-mode-map [tab] 'outline-cycle)

  (define-key outline-minor-mode-map [M-down] 'outline-move-subtree-down)
  (define-key outline-minor-mode-map [M-up] 'outline-move-subtree-up)
)
(provide 'python-magic)

我认为outline-magic已被outshine取代，但我不知道上面的代码是否适用于它。但是我通过Ryan Davis的博客文章成功地运行了以下代码：

(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)

也许有人会觉得这很有用。我认为这是一种使编辑和导航代码更容易的惊人方式。

我使用 hideshow-org（这里有一个简短的介绍）来实现此目的，我认为它非常好用。

以下是一些额外但有用的代码片段：

(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)))
