This patch needs some more work. It caused regressions with programs that use
GNU readline, etc.
Original test-case example from Tim Culverhouse <tim@timculverhouse.com>:
printf " đ" && sleep 2 && printf "\e[D" && sleep 2 && printf "\e[D" && sleep 2
After the patch it caused regressions, example test-case:
printf "Ać\bB\n"
typedef struct {
Glyph attr; /* current char attributes */
- int x; /* terminal column */
- int y; /* terminal row */
+ int x;
+ int y;
char state;
} TCursor;
void
tcontrolcode(uchar ascii)
{
- size_t i;
-
switch (ascii) {
case '\t': /* HT */
tputtab(1);
return;
case '\b': /* BS */
- for (i = 1; term.c.x && term.line[term.c.y][term.c.x - i].u == 0; ++i)
- ;
- tmoveto(term.c.x - i, term.c.y);
+ tmoveto(term.c.x-1, term.c.y);
return;
case '\r': /* CR */
tmoveto(0, term.c.y);
