1. folding for python-model

• 问一下，python-model和这个folding脚本该怎么安装？（刚开始用emacs) by flyaflya
  • 我用的windows，安装python-mode如下：创建一个 .emacs 文件放到你的 c:/ 下，.emacs内容如下：

    • (setq load-path (cons "c:/emacs/python_mode" load-path))
      (setq auto-mode-alist
            (cons '("\\.py$" . python-mode) auto-mode-alist))
      (setq interpreter-mode-alist
            (cons '("python" . python-mode)
                  interpreter-mode-alist))
      ;;(setq python-mode-hook
      ;;      '(lambda() (progn
      ;;                 (set-variable 'py-indent-offset 4)
      ;;                 (set-variable 'py-smart-indentation nil)
      ;;                 (set-variable 'indent-tabs-mode nil) )))
      (defconst py-python-command "c:/python24/python.exe")
      (autoload 'python-mode "python-mode" "Python editing mode." t)
      ;;---------------------------------------------
      ;; add my customization
      (add-hook 'python-mode-hook 'my-python-hook)
      ;; this gets called by outline to deteremine the level. Just use the length of the whitespace
      (defun py-outline-level ()
        (let (buffer-invisibility-spec)
          (save-excursion
            (skip-chars-forward "\t ")
            (current-column))))
      ;; this get called after python mode is enabled
      (defun my-python-hook ()
        ;; outline uses this regexp to find headers. I match lines with no indent and indented "class"
        ;; and "def" lines.
        (setq outline-regexp "[^ \t]\\|[ \t]*\\(def\\|class\\) ")
        ;; enable our level computation
        (setq outline-level 'py-outline-level)
        ;; do not use their \C-c@ prefix, too hard to type. Note this overides some python mode bindings
        (setq outline-minor-mode-prefix "\C-c")
        ;; turn on outline mode
        (outline-minor-mode t)
        ;; initially hide all but the headers
        (hide-body)
        ;; I use CUA mode on the PC so I rebind these to make the more accessible
        (local-set-key [?\C-\t] 'py-shift-region-right)
        (local-set-key [?\C-\S-\t] 'py-shift-region-left)
        ;; make paren matches visible
        (show-paren-mode 1)
      )
      
      ;;----------------------------------
      (custom-set-variables
        ;; custom-set-variables was added by Custom -- don't edit or cut/paste it!
        ;; Your init file should contain only one such instance.
       '(case-fold-search t)
       '(current-language-environment "English")
       '(default-input-method "latin-1-prefix")
       '(global-font-lock-mode t nil (font-lock)))
      (custom-set-faces
        ;; custom-set-faces was added by Custom -- don't edit or cut/paste it!
        ;; Your init file should contain only one such instance.
       )

      使用的时候 M-x (alt + x ) ，然后输入 python-mode 就可以启动了。 --瘦青蛙
    • 谢谢瘦青蛙提供配置文件。可是我还没有体会出这么复杂的配置emacs的好处。目前，我是把空格数量当作确定outline级别的依据。不知道py-outline-level什么意思。另外，发现这里有人已经提到了folding，当时，我还以为是outline的一种称呼。现在，我比较重度的使用folding来代替leo。 - tomz

    • python-mode中是不带folding的. 上面那个缩进使用的是Emacs自带的outline-minor-mode. 原帖见: http://groups.google.ca/group/comp.lang.python/browse_thread/thread/43a4d75404cc64fe/956f1c2d37f93995?&hl=en#956f1c2d37f93995 -- ["nickcheng"]

• 嗯嗯？感觉折叠和Leo的节点还是有区分的，前者是通过预先约定的语法原则，Leo 则是完全的根据需要，不同的理念吧……ZoomQuiet

  • folding不是outline那样根据语法规则来确定折叠。而是能够随意选择一部分来折叠。这样，在emacs中就有了两种折叠方式。一个是随意的折叠，就像leo那样，另外，是根据语法来折叠，这样，就不用象leo那样，每个函数还要再分别定义节点，减少了这个重复工作量。而且，用folding这种方式，就没有leo那样的预处理过程，完全就在python文件中操作。同时和python－mode相结合，能够方便的调试。当然，不像leo这样专门的工具那样友好。所以，我建议还是体会leo的感觉，才能体会到folding到底有多重要。 -tomz
