ATTENTION: original code works _only_for_ FULLWIN, i.e. if you use two FULLLINE windows like in 'talk', you have full slow repaint with original code, I enhance this thing.

I rewrite scroll code too for proper working (see below and tty.c changes). o DEBUG code always use 'i' index from 0 to curscr->maxy instead of 'i - win->begy', fixed o check added into DEBUG to be shure that index inside current window. o ->hash assigment code is WFNFW (forget win->begy). o when CE usage required, and last spaces number counted, code don't check attributes, so last standouted space will be incorrectly cleared. o cep (start pointer) forget to add win->begy/win->begx, code WFNFW. o clsp (last space) wrong in two places at once: forget to add win->begy (WFNFW) and incorrectly use 'win->begx * __LDATASIZE' in pointer arithmetics. o clsp check incorrect: was 'clsp < win->maxx * __LDATASIZE', need to be 'clsp < win->maxx o Attributes does not turned off before clearing end of line, cause highlighted end of line. o When find how many lines from the top/bottom of the screen are unchanged, code always forget '- win->begy', WFNFW. o NO_JERKINESS code forgets to add win->begy, WFNFW. o Curw & Curs changed in comment description o In search for the largest block of text not changed forget to add '- win->begy' (several places), WFNFW. o Forget to add '- win->begy' for non-dirty lines, WFNFW. o touchline forget to add '- win->begy', WFNFW. o rewrite scrolln(): * remove win parameter, we deal with whole screen (curscr) now; * use NL or '\n' instead of sf, it is faster in any case; (imagine: cat written on curses now use '\n' for scroll like standard cat, no ugly escapes) * use dl (if present) instead of DL, if abs(n) == 1, the same about al/sr, it is faster; * change win->maxy to 'curscr->maxy - 1', we deal with whole screen here, WFNFW. * SF can be correctly issued only if cursor at bottom of scroll region (whole screen region included too), fix this; * sr/SR can be correctly issued only if cursor at top of scroll region (whole screen region included too), fix this; * use pre-calculaded (in setterm.c) __usecs variable to determine usage of CS or AL/DL; * completely rewrite scroll region stuff using __set_scroll_region from tty.c (see below); tty.c o Added __set_scroll_region function which set CS region and stays back in old position.

Define _tty like __baset too. o Typedef SGTTY type for old applications (SGTTY == struct termios). o wstandout/wstandend should be int and not char*, some old applications relay on this fact. See standout.c too. o __FULLINE added indicated line width == terminal width, needed for refresh using AL/DL/CS with __noqch, see refresh.c changes. o Add extern __usecs variable that indicates usage of CS (if AL/DL absent). o Add __set_scroll_region() prototype, see tty.c and refresh.c changes for details. o Change winch() character mask from 0177 to 0377, we don't need to strip high bit on national characters. o Allow translate on systems with _BSD_VA_LIST_ undefined, such as FreeBSD 1.1.5.1 o __tty_fileno added to allows work with stdin redirected, see tty.c o Privately declare tputs (..., void) and externally tputs(..., int), many applications require this.

1995-05-30 05:51:47 +00:00
* 2. As a result of the use of the mod function, there may be a
1994-05-27 05:00:24 +00:00
* period introduced, i.e., 2 maps to 4, 4 to 6, n-2 to 0, and
* 0 to 2, which then causes all odd lines not to be rotated.

Use SC/RC (save/restore cursor) if possible, else use HO and __mvcur. o __startwin: added __set_scroll_region(whole screen) at program startup, if __usecs; o endwin: added __set_scroll_region(whole screen) at program exit, if __usecs; o Fix all tc{set/get}attrs to works properly, when stdin redirected, use /dev/tty in this case (needed for some applications). setterm.c o Add new variable __usecs, if (!AL/al || !Dl/dl) && CS && (SC && RC || HO) (save/restore cursor used in __set_scroll_region in tty.c). o Set __noqch, if !__usecs && (!AL/al || !DL/dl). o Proper ospeed initialization for tputs, i.e. if speed == B9600, ospeed = 13 curses.c o Add __usecs variable that indicates usage of CS (if AL/DL absent). curses.h o Allow translation with applications which includes <sgtty.h>, undef BXXX manually to avoid redefinition and include termios to define proper ones. o Define old-style names curx/begx/maxx/etc. for old applications. Define _tty like __baset too. o Typedef SGTTY type for old applications (SGTTY == struct termios). o wstandout/wstandend should be int and not char*, some old applications relay on this fact. See standout.c too. o __FULLINE added indicated line width == terminal width, needed for refresh using AL/DL/CS with __noqch, see refresh.c changes. o Add extern __usecs variable that indicates usage of CS (if AL/DL absent). o Add __set_scroll_region() prototype, see tty.c and refresh.c changes for details. o Change winch() character mask from 0177 to 0377, we don't need to strip high bit on national characters. o Allow translate on systems with _BSD_VA_LIST_ undefined, such as FreeBSD 1.1.5.1 o __tty_fileno added to allows work with stdin redirected, see tty.c o Privately declare tputs (..., void) and externally tputs(..., int), many applications require this.

newwin.c o __FULLINE added for AL/DL/CS optimization with __noqch. refresh.c o Attributes does not turned off before clearing screen, cause highlighted screen. o Proper usage of 'affcnt' tputs parameter, affects terminals with padding. o make AL/DL/CS optimize not only for __FULLWIN but for __FULLLINE. ATTENTION: original code works _only_for_ FULLWIN, i.e. if you use two FULLLINE windows like in 'talk', you have full slow repaint with original code, I enhance this thing.

Use SC/RC (save/restore cursor) if possible, else use HO and __mvcur. o __startwin: added __set_scroll_region(whole screen) at program startup, if __usecs; o endwin: added __set_scroll_region(whole screen) at program exit, if __usecs; o Fix all tc{set/get}attrs to works properly, when stdin redirected, use /dev/tty in this case (needed for some applications). setterm.c o Add new variable __usecs, if (!AL/al || !Dl/dl) && CS && (SC && RC || HO) (save/restore cursor used in __set_scroll_region in tty.c). o Set __noqch, if !__usecs && (!AL/al || !DL/dl). o Proper ospeed initialization for tputs, i.e. if speed == B9600, ospeed = 13 curses.c o Add __usecs variable that indicates usage of CS (if AL/DL absent). curses.h o Allow translation with applications which includes <sgtty.h>, undef BXXX manually to avoid redefinition and include termios to define proper ones. o Define old-style names curx/begx/maxx/etc. for old applications.
