printing to right side or bottom side of terminal using (n)curses
What's the standard way to print to the right side and/or bottom side of the terminal window using n/curses?
Here's a little 开发者_高级运维sketch:
Terminal window:
================================================================================
[ MSG ]
message number 2 here is more
================================================================================
Solutions in C or Python are fine.
Thanks!
I'd go with:
mvprintw(COLS-length("msg"),1,"msg");
mvprintw(0,LINES-1,"message number 2");
mvprintw(COLS-length("here is more"),LINES-1,"here is more");
That's kinda off the cuff, which is how I do most of my curses programming.
There are 2 ways that I know of, but only one I'm sure of:
ONE:
move(int row, int col)
from the ncurses library. But, if you are going to perform some I/O after this statement, you are metter off using the corresponding 'mv' function. For example,
move(y, x);
addch(ch);
can be replaced by
mvaddch(y, x, ch);
NOTE: I've only head of this but haven't tested it myself.
TWO:
printf("\033[%d;%df", y, x);
fflush(stdout);
printf("Hello, I will be placed at (x,y)\n");
I'm sure this one works.
Good Luck!
I wrote this bit of code to work around the problem automatically. Call this instead of scr.addstr() and it will take care of doing the right addstr/insstr commands to make it work.
def cwrite(scr, row, col, str, attr=0):
max = scr.getmaxyx()
if row < max[0] - 1:
scr.addstr(row, col, str, attr)
elif row == max[0] - 1:
if len(str) + col >= max[1]:
offset = max[1] - col - 2
scr.addstr(row, col, str[:offset])
scr.addstr(row, max[1] - 2, str[offset + 1], attr)
scr.insstr(row, max[1] - 1, str[offset], attr)
else:
scr.addstr(row, col, str, attr)
