Readline stuff seems nice. As a test, just for make this lib work, you
can base your code on (based on the links and suggestions of this same
thread):
[rodolfoap] /home/rodolfoap/dat/devel > cat rl.c
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <signal.h>
#include <readline/readline.h>
#include <readline/history.h>
#define PROMPT "$ "
void handle_signal(int signo) {
printf("\n%s", PROMPT);
fflush(stdout);
}
int main(int argc, char **argv, char **envp){
signal(SIGINT, SIG_IGN);
signal(SIGINT, handle_signal);
char *temp = NULL;
while ((temp=readline(PROMPT)) != NULL) {
if (*temp) {
system(temp);
add_history (temp);
}
if (strcmp (temp, "exit") == 0){
free(temp);
break;
}
free (temp);
}
return 0;
}
[rodolfoap] /home/rodolfoap/dat/devel > gcc rl.c -lcurses -lreadline
-lhistory -o rl
[rodolfoap] /home/rodolfoap/dat/devel > ./rl
