Emacs Python IDE win7 x64

安装平台 win7 x64 ,emacs 23.3.1

1. YASnippet

snippet工具,可自定义一些模板:

http://yasnippet.googlecode.com/files/yasnippet.avi
上面是演示demo

.emacs 配置如下

(add-to-list 'load-path "~/.emacs.d/yasnippet")
(require 'yasnippet) ;; not yasnippet-bundle
(yas/global-mode 1)

 

2. AutoComplete

自动完成工具,其实只是一个前端工具。当然也可以用ropemacs 作为它补全的后端使用。

.emacs 配置如下:

(add-to-list 'load-path "~/.emacs.d/")
(require 'auto-complete-config)
(add-to-list 'ac-dictionary-directories "~/.emacs.d//ac-dict")
(ac-config-default)

 

3. Python-mode

安装python-mode :

http://www.loveshack.ukfsn.org/emacs/#python.el 下载后直接丢到load-path 中

4.Rope and Ropemacs

Ropemacs非常棒的重构工具,比如rename,move,extract method等等。还有非常好用的goto difinition(跳到定义),show documents(显示文档)、代码补全等等。安装Ropemacs前,必须先安装ropepymacs 实际上还要安装rope-mode。

rope的安装方法:

python setup.py install

pymacs的win上安装方法:

python pppp -C ppppconfig.py pppp.rst.in pymacs.el.in \  pymacs.rst.in Pymacs contrib tests
python setup.py install

注意此处:我git pymacs到本地后无法install成功,后来别人给一个pymacs包,我放在git的pymacs里,重新执行上面的安装方法后,成功。pymacs包见本文尾

如果成功,则在python环境中输入以下,不会报错:

from Pymacs import lisp

.emacs中:

(autoload 'pymacs-apply "pymacs")
(autoload 'pymacs-call "pymacs")
(autoload 'pymacs-eval "pymacs" nil t)
(autoload 'pymacs-exec "pymacs" nil t)
(autoload 'pymacs-load "pymacs" nil t)

注意完成后,将下图552行的Pymacs.pymacs 改成Pymacs

Ropmacs的安装方法:

python setup.py install

.emacs中:

(require 'pymacs)
(pymacs-load "ropemacs" "rope-")
(setq ropemacs-enable-autoimport t)

注意:ropemacs时,先将ropemacs解压缩,然后将刚刚安装好的ropemode拷贝进去,再执行安装,否则会出错。C:\Python27\Lib\site-packages\ropemacs

基本操作

rope-code-assist, M-/    
Code completionrope-rename, C-c r r   
Rename a variable, function, etc.

5.程序调试

在Emacs中,通过M-x pdb可调出pdb对python代码进行调试。但是发现在Windows系统中,总进入不了调试模式。主要原因有:

1. windows中,找不到pdb.py位置。需自己制定pdb的路径。可以通过下面的方法设置pdb的路径:

;; pdb setup, note the python version
(setq pdb-path 'c:/python25/Lib/pdb.py
       gud-pdb-command-name (symbol-name pdb-path))
 (defadvice pdb (before gud-query-cmdline activate)
   "Provide a better default command line when called interactively."
   (interactive
    (list (gud-query-cmdline pdb-path
                 (file-name-nondirectory buffer-file-name)))))

 

2. windows中,调用pdb时,未使用python -i 参数。

针对上面两个问题,我的解决办法是,不设置pdb具体路径,M-x pdb 回车后,出现下面命令:

Run pdb (like this): pdb 

然后手动修改一下:

Run pdb (like this): python -i -m pdb test.py

6.代码检查

基本上都是flymake+pyflakes 或者 flymake +pylint模式,我选择了前者。并安装了pep8

flymake是emacs自带的,下载pyflakes 和pep8 安装好后,按下面配置好即可:

c-c c-w是执行命令!

注意pyflakes 和pep8 都是在cmd中执行命令的。

;pycheck grammer ; indent something
(add-to-list 'load-path "~/.emacs.d/")
(add-hook 'find-file-hook 'flymake-find-file-hook)
(when (load "flymake" t)
  (defun flymake-pyflakes-init ()
    (let* ((temp-file (flymake-init-create-temp-buffer-copy
               'flymake-create-temp-inplace))
       (local-file (file-relative-name
            temp-file
            (file-name-directory buffer-file-name))))
      (list "pychecker"  (list local-file))))
   (add-to-list 'flymake-allowed-file-name-masks
             '("\\.py\\'" flymake-pyflakes-init)))
(load-library "flymake-cursor")
;(global-set-key [f10] 'flymake-goto-prev-error)
;(global-set-key [f11] 'flymake-goto-next-error)
(setq python-check-command "pyflakes")

 

然后创建一个pychecker.bat的文档 丢到python里面,我的目录是c:\python27

python C:\Python27\runpyflakes.py  %*
pep8 --ignore=E221,E701,E202 --repeat %*

再在该目录创建一个runpyflakes.py的程序

from pyflakes.scripts.pyflakes 
import mainmain()

效果如下:

7.文档帮助

我还是喜欢firefox直接上官方文档库查找。

emacs wiki 也给出了sphinx后格式的文档下载,可以直接在emacs info里查看帮助。

具体链接请见本文末尾处效果可以看最后一个链接。

 

8.段落注解:

Comment/Uncomment Region

If you have ‘transient-mark-mode’ on, you can just use ‘comment-dwim’:

select a region and hit ‘M-;’.

The DoWhatIMean means that it will comment or uncomment the region as appropriate.

If you do not have ‘transient-mark-mode’ on by default, you can hit C-SPC twice to activate it temporarily.

( doesn’t python-mode.el offer `py-comment-region? --CH )

You can also use “rectangles” with comment/uncomment region (among other things that you can do with rectangles).

See RectangleCommands or “(emacs) Rectangles” in the Emacs manual.

9.框架支持

django: https://code.djangoproject.com/wiki/Emacs" 如果不是很熟悉的话,还是建议用pycharm来写吧。

10.测试
