Using ncurses in Linux console C program

- Install the library: $ sudo apt-get install ncurses-dev
- To compile: $ gcc -o hello hello.c -lncurses

Basis:

#include <ncurses.h>
int main(){
  initscr();
  printw("Hello World!");
  wrefresh(curscr);  // adapt output to terminal, like windows console.
  getch();
  endwin();
  return 0;
}

Move cursor:

move(12, (40-5));  // center the string 'Hello World!' on a  80, 25 screen.  format is: move(y, x);
To combine move and print use mvprint(y, x, string).

Form like behavior:

#include <ncurses.h>
int main(){
  int sz=40;
  char name[sz];
  initscr();
  addstr("Name: ");
  refresh();
  getnstr(name, sz-1);
  printw("Hello, %s", name);
  getch();
  endwin();
  return 0;
}

Border and colored text:

#include <ncurses.h>
int main(){
  initscr();
  border(0, 0, 0, 0, 0, 0, 0, 0);
  move(1,1);
  if(has_colors()){
    start_color();
    init_pair(1, COLOR_WHITE, COLOR_BLUE);
    attrset(COLOR_PAIR(1));
  }
  mvprintw(12, 35, "Hello World!");
  wrefresh(curscr);
  getch();
  endwin();
  return 0;
}
