pymacs-settings.el配置python自动补全

下载pymacs，解压到任意一个目录中，如:我的是[B.Qnyd@localhost 下载]$ ls -l
将会看见pymacs 的python代码源包,解压就行了....

进入其中 执行 python setup.py install 可以先执行python setup build 然后安装rope ropemacs来很好的配合python让他具有IDE的项目管理功能,首先执行下面的命令下载源代码下来

$hg clone http://bitbucket.org/agr/rope/
$hg clone http://bitbucket.org/agr/ropemacs/
$hg clone http://bitbucket.org/agr/ropemode/

然后分别进入rope ropemacs 里面执行
python setup.py install
把三个文件分别移动到你的path下面如:

mv rope* /home/B.Qnyd/lisp/

如果你还想要它检查你的语法是否正确,你就需要安装pyflakes
我的是fedora 直接安装
yum install pyflakes
其他系统可以用sudo apt-get install 等系统默认的在线安装包...
(注意这个python-setuptools东西必不可少,一样执行
yum install python-setuptools)
然后.
新建一个pymacs-settings.el 把以下代码加入进去:

(setq pymacs-load-path '("~/lisp/rope"




"~/lisp/ropemacs"))


(autoload 'python-mode "python-mode" "Python Mode." t)


(add-to-list 'auto-mode-alist '("\\.py\\'" . python-mode))


(add-to-list 'interpreter-mode-alist '("python" . python-mode))


(require 'python-mode)

))

(provide 'pymacs-settings)


然后在你的.emacs 里面加入 (load "pymacs-settings")这样你就给你的emacs扩展了自动补全,

建立工程了.不比任何IDE差...... 不过首先你得配置好,不然你就会觉得它很差劲....
