with ring buffer + + This patch adds a ring buffer for scrollback to the terminal. The + advantage of using a ring buffer is that the common case, scrolling with + no static screen content, can be achieved very efficiently by + incrementing and decrementing the starting line (modulo buffer size). + + The scrollback buffer is limited to HISTSIZE lines in order to bound + memory usage. As the lines are allocated on demand, it is possible to + implement unlimited scrollback with few changes. If the terminal is + reset, the scroll back buffer is reset, too. + +diff --git a/config.def.h b/config.def.h +index 2cd740a..8b25d40 100644 +--- a/config.def.h ++++ b/config.def.h +@@ -201,6 +201,8 @@ static Shortcut shortcuts[] = { + { TERMMOD, XK_Y, selpaste, {.i = 0} }, + { ShiftMask, XK_Insert, selpaste, {.i = 0} }, + { TERMMOD, XK_Num_Lock, numlock, {.i = 0} }, ++ { ShiftMask, XK_Page_Up, kscrollup, {.i = -1} }, ++ { ShiftMask, XK_Page_Down, kscrolldown, {.i = -1} }, + };
