Hi,
I'm using the readline library (part of bash, which is why I post here).
Works great, but I notice that after
line = readline("?- ");
(or any other non-empty string), there is no way to get rid of the
prompt. Both after readline("") and readline(NULL) it still prompts me
with "?- ". From the source, I see calling rl_set_prompt() is the same
as this is called right away from readline(). The prompt logic is a bit
too complicated to track it down easily for me.
I guess this is a bug. It could be argued that readline(NULL) keeps
the current prompt, but readline("")??
Anyone to confirm? Is there an easy hack around? I would be glad if
my software (SWI-Prolog) runs with existing readline shared objects.
Thanks --- Jan
