Python IDLE 代码高亮主题

使用方法：

打开C盘我的 C:Documents and Settings你的用户名.idlerc文件夹
里面会有一个 config-highlight.cfg 如果没有请自已创建一个
将下面的代码放到 config-highlight.cfg 里面，并重启IDLE
这下在IDLE的设置highlight项里面就有几个主题了

首先要找到名为config-highlight.cfg的文件，这个文件位于哪里呢？我列了一份可以找到它的路径清单
在Linux系列系统下路径为（~表示用户目录）：
~/.idlerc/
在Windows XP下路径为：
C:Documents and Settings<用户名>.idlerc
在Windows 7下路径为：
C:Users<用户名>.idlerc
对于Windows可以直接打开开始运行或者在地址栏输入下面的路径确认即可：
%USERPROFILE%.idlerc找到这个名叫config-highlight.cfg文件后接下来就需要编辑它了，怎么？找不到？没关系，我们可以新创建一个config-highlight.cfg。
当然，说到编辑，命令控们也可以尝试下面的命令，在Linux系统下：

在Linux下
vi ~/.idlerc/config-highlight.cfg

在Windows系统下：
notepad %USERPROFILE%.idlercconfig-highlight.cfg好了，现在我们应该已经打开config-highlight.cfg这个文件并做好编辑的准备了，比如说我可以通过修改这个文件为下面内容来实现两个名为Obsidian和tango的代码高亮主题：

我们修改了config-highlight.cfg这个文件并不意味着事情结束了，我们还需要在Python IDLE中选择我们的主题，这时如果已经打开Python IDLE，请保存必要文件并重新开启IDLE，开启后依次选择菜单上Options – Configure IDLE…
选择Highlighting选项卡，然后Select选择a Custom Theme，如下图所示，选择刚才配置的两个主题之一，我这里选择tango。
完成配置后点击Apply或者OK，看看效果吧，有童鞋要问字体怎么配置？这个容易，在Highlighting选项卡旁边有个Fonts/Tabs选项卡，可以用来配置字体和缩进宽度的：
好了，做完这些一个崭新的界面就应该呈现了，如果看不到效果请重启Python IDLE。

Python IDLE配置清屏快捷键（Ctrl+L）

在PythonLibidlelib下，新建一个ClearWindow.py文件（没有时就新建），内容如下：

"""

Clear Window Extension
Version: 0.2

Author: Roger D. Serwy
        roger.serwy@gmail.com

Date: 2009-06-14

It provides "Clear Shell Window" under "Options"
with ability to undo.

Add these lines to config-extensions.def

[ClearWindow]
enable=1
enable_editor=0
enable_shell=1
[ClearWindow_cfgBindings]
clear-window=<Control-Key-l>


"""

class ClearWindow:

    menudefs = [
        ('options', [None,
                ('Clear Shell Window', '<<clear-window>>'),
        ]),]

    def __init__(self, editwin):
        self.editwin = editwin
        self.text = self.editwin.text
        self.text.bind("<<clear-window>>", self.clear_window2)

        self.text.bind("<<undo>>", self.undo_event)  # add="+" doesn't work

    def undo_event(self, event):
        text = self.text

        text.mark_set("iomark2", "iomark")
        text.mark_set("insert2", "insert")
        self.editwin.undo.undo_event(event)

        # fix iomark and insert
        text.mark_set("iomark", "iomark2")
        text.mark_set("insert", "insert2")

        text.mark_set("iomark", 1.0)
        text.delete(1.0, "iomark2 linestart")
        text.mark_set("iomark", "iomark2")
        text.mark_unset("iomark2")

        # clear the window, but preserve current command
        self.text.delete(1.0, "iomark linestart")
        if self.text.compare('insert', '<', 'iomark'):
            self.text.mark_set('insert', 'end-1c')
        self.editwin.set_line_and_column()

        # restore undo delegator
        self.editwin.per.insertfilter(undo)

PythonLibidlelib下修改config-extensions.def ，在末尾添加如下内容：

[ClearWindow]
enable=1
enable_editor=0
enable_shell=1
[ClearWindow_cfgBindings]
clear-window=<Control-Key-l>

重新Python的IDLE，在options选项中就可以看到增加了Clear shell Window Ctrl+L，即清屏的快捷键为：Ctrl+L
