最近在学习Python,好很多简单的练习就直接在IDLE Shell里敲了,但发现一个问题,随着内容的增多,会弄得满屏都是,看起来很不舒服。于是就诞生了此文,此文多数内容摘自网络,并非原创,如有不道之处,请指出,谢谢!
编辑IDLE配置文件
该文件位于Python
安装目录下的Lib\idlelib\
目录里,名称为config-extensions.def
,用文件编辑工具打开,并在文档最后插入如下内容:
[ClearWindow]
enable=1
enable_editor=0
enable_shell=1
[ClearWindow_cfgBindings]
clear-window=<Control-Key-l>
添加ClearWindow.py文件
把该文件同样放在Python
安装目录下的Lib\idlelib\
目录里,然后重启IDLE就可以,是不是很简单。
ClearWindow.py
文件的下载地址为:https://bugs.python.org/file14303/ClearWindow.py
也可以直接复制以下代码保存为ClearWindow.py
:
"""
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_unset("iomark2")
text.mark_unset("insert2")
def clear_window2(self, event): # Alternative method
# work around the ModifiedUndoDelegator
text = self.text
text.undo_block_start()
text.mark_set("iomark2", "iomark")
text.mark_set("iomark", 1.0)
text.delete(1.0, "iomark2 linestart")
text.mark_set("iomark", "iomark2")
text.mark_unset("iomark2")
text.undo_block_stop()
if self.text.compare('insert', '<', 'iomark'):
self.text.mark_set('insert', 'end-1c')
self.editwin.set_line_and_column()
def clear_window(self, event):
# remove undo delegator
undo = self.editwin.undo
self.editwin.per.removefilter(undo)
# 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)
建议直接下载,如果复制的话,注意查看代码格式,比如缩进有没有乱掉,如果乱掉的话是会报错的
最终效果图如下,按下Ctrl + L
键就可以清屏了
