Version: 6.1
Machine: I have tested this on Core, Core2
OS: Linux 2.6.34 (ArchLinux)
Configuration: ./configure CFLAGS=-g
Description: Readline doesn't update its internal data about screen size when
terminal is in noecho mode.
Recipe:
#include <stdio.h>
#include <stdlib.h>
#include <ncurses.h>
#include <readline/readline.h>
int main(void)
{
char * line;
initscr();
noecho();
line = readline("> "); free(line);
echo();
endwin();
line = readline("> "); free(line);
return 0;
}
Start the application, make the terminal bigger (make sure it has more
columns). Press Enter. Now start typing. You will notice that readline doesn't
fully go till the right side of the terminal, but only till the middle.
Possible bugfix:
Whenever we enable echoing (_rl_echoing_p is set to 1) we also should update
screen size. _rl_echoing_p is set in multiple places so I think this should be
refactored into a function.
