I would like to use the Gnu readline function in D. Is there a
module that i can use?
just define it yourself

// this line right here is all you need to call the function
extern(C) char* readline(const char*);
import core.stdc.stdio;
void main() {
char* a = readline("prompt> ");
printf("%s\n", a);
}

dmd rl -L-lreadline
readline is so simple you don't need to do anything fancier. If
you need history and such too you just define those functions
as well.
Dear Adam,
I did exactly just what you proposed.
When 'dmd rl -L-lreadline' in the command line. I do get the
following error:
Error: module rl is in file 'rl.d' which cannot be read.
So probably I'm missing something unfortunately I don't know what.
