python shell prompts should not be editable

[Russell Sim]

Hey,

From a prompt like,
>>>
it would be nice if pressing backspace didn't result in parts of the prompt being deleted like,
>>

I have used slime extensively and one nice piece of usability that it has is a prompt that isn't editable, eshell also has this feature. I wasn't able to figure out how they do this in slime but in eshell there are hooks that are run when you enter/exit the prompt area, that change some of the keybindings. so when you are in the prompt the backwards-word and character functions that won't jump past the prompt and the backspace key won't allow you to delete the prompt.

any alternative thoughts on how this could be implemented?

Cheers,
Russell

would think at property setting, i.e. making the prompt area intangible.

I found a facility in comint mode to enable readonly prompts, i have added it as a buffer local variable and added a config option

Thanks, however, don't think it's needed as an option.
We never edit the prompt, it's just a bug.
