python的IDEL编辑器清屏文件配置

1.找到Python\PythonX\Lib\idlelib(x为你的版本号)，在当前目录下添加ClearWindow.py，复制提供的代码，保存为*.py即可。

 1 class ClearWindow:
 2
 3     menudefs = [
 4         (‘options‘, [None,
 5                (‘Clear Shell Window‘, ‘<<clear-window>>‘),
 6        ]),]
 7
 8     def __init__(self, editwin):
 9         self.editwin = editwin
10         self.text = self.editwin.text
11         self.text.bind("<<clear-window>>", self.clear_window2)
12
13         self.text.bind("<<undo>>", self.undo_event)  # add="+" doesn‘t work
14
15     def undo_event(self, event):
16         text = self.text
17
18         text.mark_set("iomark2", "iomark")
19         text.mark_set("insert2", "insert")
20         self.editwin.undo.undo_event(event)
21
22         # fix iomark and insert
23         text.mark_set("iomark", "iomark2")
24         text.mark_set("insert", "insert2")
25         text.mark_unset("iomark2")
26         text.mark_unset("insert2")
27
28
29     def clear_window2(self, event): # Alternative method
30         # work around the ModifiedUndoDelegator
31         text = self.text
32         text.undo_block_start()
33         text.mark_set("iomark2", "iomark")
34         text.mark_set("iomark", 1.0)
35         text.delete(1.0, "iomark2 linestart")
36         text.mark_set("iomark", "iomark2")
37         text.mark_unset("iomark2")
38         text.undo_block_stop()
39         if self.text.compare(‘insert‘, ‘<‘, ‘iomark‘):
40             self.text.mark_set(‘insert‘, ‘end-1c‘)
41         self.editwin.set_line_and_column()
42
43     def clear_window(self, event):
44         # remove undo delegator
45         undo = self.editwin.undo
46         self.editwin.per.removefilter(undo)
47
48         # clear the window, but preserve current command
49         self.text.delete(1.0, "iomark linestart")
50         if self.text.compare(‘insert‘, ‘<‘, ‘iomark‘):
51             self.text.mark_set(‘insert‘, ‘end-1c‘)
52         self.editwin.set_line_and_column()
53
54         # restore undo delegator
55         self.editwin.per.insertfilter(undo)

ClearWindow.py

2.在当前目录下找到config-extensions.def 并修改，在末尾添加如下代码：

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

配置内容

3. 重新打开IDEL即可，如果快捷键无效的话，注意查看ClearWindow.py的大小写以及配置文件内容的大小写状态
