Thread: Problem with skipping columns for drawing in a text editor.

Hi all, my problem is with e.skipcols in KEY_RIGHT and KEY_END case in the switch statement. Cannot seem to get the math right on skipping columns. It either goes before the end of line or after.
Please help, the full code is below. Thanks in advance to any help in resolving this issue.

EDIT: It already skips columns but it goes to far (greater than the length of the current line).

NOTE: To compile use the given command below.

Code:

$ gcc -std=c11 -W -O0 -g -o psedit main.c -lncurses

main.c

I fixed it, now it all works. Never mind, I should've looked at my code closer. The code that works perfect is below.

Code:

            case KEY_END:
                startx = editor_getoffset(&e, e.cy + e.skiprows);
                endx = editor_getoffset(&e, (e.cy + e.skiprows) + 1);
                if((e.cx + e.skipcols) < (e.cols - 1) &&
                    (e.cx + e.skipcols) < (endx - startx)) {
                    int len = (endx - startx) - 1;
                    int skipcols = len - e.cols + 1;
                    int skipcx = (len - skipcols) % e.cols;

                    // Calculate how many columns to skip.
                    e.skipcols = (len >= e.cols ? skipcols: 0);
                    // Calculate how many columns left from length.
                    e.cx = len >= e.cols ? skipcx : len > 0 ? len : 0;
                    e.dirty = true;
                }
            break;

Thanks anyway.
