Linux下,clear还是可以清屏,但是Ctrl+l没有反应,不能清屏,但是个人比较喜欢Ctrl+l这个指令,求大神指点迷津~~~
Ctrl+l指令今早突然可以了,刚才试了下,又不能用了
其他快捷键指令正常
本来也可以的,不知道怎么回事,不行了
追答呵呵,那这个问题奇葩了啊,怎么出现这情况,你知道了告诉我哈
本回答被提问者和网友采纳Python IDLE配置清屏快捷键(Ctrl+L)
1.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 [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)
2.PythonLibidlelib下修改config-extensions.def ,在末尾添加如下内容:
1[ClearWindow] enable=1 enable_editor=0 enable_shell=1 [ClearWindow_cfgBindings] clear-window=<Control-Key-l>
3.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
