Trash: Cookbook Defining prompts via hooks - ShuaiYAN/ipython GitHub Wiki

The following example code shows how to define input and output prompts via hooks:

 def myinputprompt(self, cont):
     ip = self.api
     count = str(len(ip.user_ns["_ih"]))
     colors = Prompts.PromptColors[""].colors
     pwd = os.getcwd()
     if cont:
         return "%s%s%s: " % ( \
             colors.in_prompt2,
             "."*(4+len(pwd)+1+len(count)+1),
             colors.normal)
     else:
         return "%sIn [%s|%s%s%s]: %s" % ( \
             colors.in_prompt,
             pwd,
             colors.out_number,
             count,
             colors.in_prompt,
             colors.normal)
 
 def myoutputprompt(self):
     ip = self.api
     count = str(len(ip.user_ns["_ih"]))
     colors = Prompts.PromptColors[""].colors
     pwd = os.getcwd()
     prompt = "%sOut[%s|%s%s%s]: %s" % ( \
         colors.out_prompt,
         pwd,
         colors.out_number,
         count,
         colors.out_prompt,
         colors.normal)
     return prompt
 
 ipapi.get().set_hook("generate_prompt", myinputprompt)
 ipapi.get().set_hook("generate_output_prompt", myoutputprompt)
