readline library

[Patrick Rotsaert]

Hello,

 

I am trying to customize an interactive application (console), which uses the readline function. I would like to customize it's prompt color (e.g. when running on production system). I soon found out that including the color escape sequences in the prompt is a bad idea (length problems).

Browsing the web I found that rl_startup_hook and rl_pre_input_hook can do the job, but only when the library displays the initial prompt. When it is redrawn, these hooks are not called.

What is the most convenient way (i.e. least effort necessary) to fix this?

 

Thanks in advance,

Patrick Rotsaert
