实现步骤:
新建ClearWindow.py
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)
将ClearWindow.py复制到python安装目录下的Lib\idlelib目录(比如我的是:D:\Softwares\Python\Python310\Lib\idlelib)
修改idlelib目录下的config-extensions.def。修改之前最好先复制一份作为备份。
在文件末尾添加如下内容:
[ClearWindow]
enable = True
enable_editor = False
enable_shell = True
[ClearWindow_cfgBindings]
clear-window = <Control-Key-l>
保存文件并关闭。
启动IDLE
点击"Options",会发现多了一个选项“Clear Shell Window”。
随便输入一些指令
按快捷键Ctrl+L(或者鼠标点击“Options”,选择“Clear Shell Window”。
再输入指令,发现能正常使用。
