第一步:在 C:\Python37\Lib\idlelib 目錄下新建ClearWindow.py檔案,將一下程式碼複製到檔案中
""" Clear Window Extension Version: 0.2 Author: Roger D. Serwy [email protected] 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)
第二步:在剛才的目錄下找到configextensions.def配置檔案並開啟,將下面程式碼複製到最後面,儲存退出
[ClearWindow]
enable=1
enable_editor=0
enable_shell=1
[ClearWindow_cfgBindings]
clear-window=<Control-Key-l>
第三步:重新開啟IDLE,看看工具欄中的options選項下是不是多了一個clear shell window Ctrl + L
如果是證明你成功了,如果沒有回去檢查下ClearWindow檔案是不是小寫命名的,注意大寫。
之後可以使用快捷鍵 Ctrl + L 進行清屏了,是不是很方便 :D)
