I am currently using libedit for "readline"-functionallity, so far it works really well, but I would like to display characters (spaces) after the prompt which are deleteable by the user. Similiar to IPython:
As you can see there are 4 additional characters (spaces) automatically added, which I can remove by pressing backspace, until I reach the prompt ...:.
I would like to mimic this behaviour with libedit/editline and if there is no way to do this (e.g. using curses or the underlaying terminal function which libedit uses), I would switch to readline.
How is this possible to do, preferable with libedit/editline or readline.
Edit: I tried modifying rl_line_buffer, this didn't modify the display, only the value I get from readline.
