Re: [Help-bash] read -ep and ANSI colour sequences

Thanks for all the information folks.

I need to use readline with -e so that the arrow keys, completion etc.
work as expected.

I like using ctrl+w to delete a word and without readline (-e) then it
also deletes the prompt when using printf (for prompt ANSI sequences)
before calling read :(

The use case is an interactive shell program. FYI, I am using bash-4.2.

I like programs to appear aesthetically pleasing *and* work as
expected. It appears to me from my research into this and other issues
with command completion in interactive shell programs written in bash
that it's awkward to get this kind of complex behaviour.

I would of course be very happy to be corrected!
