我们从Python开源项目中,提取了以下13个代码示例,用于说明如何使用readline.clear_history()。
def __exit__(self, ex_tp, ex_val, ex_tb): if not haveReadline: return False try: # update the history for this project readline.write_history_file(self.historyFile) except Exception as E: print "Failed to write history to {0} - {1}".format(self.historyFile, E) # put back the original history! readline.clear_history() readline.read_history_file(self.oldhistFile) os.unlink(self.oldhistFile) # and put back the old completer readline.set_completer(self.oldCompleter) # linegenerators, pass one of these to the "run" # method of the CommandLineInterface object #import ctypes #rllib = ctypes.cdll.LoadLibrary("libreadline.so") #rl_line_buffer = ctypes.c_char_p.in_dll(rllib, "rl_line_buffer") #rl_done = ctypes.c_int.in_dll(rllib, "rl_done")
