From cd6982e5da1f5facdc1e0154b3a27c01e8b076c9 Mon Sep 17 00:00:00 2001 From: mrb0nk500 Date: Wed, 27 Jan 2021 13:42:57 -0500 Subject: - Fixed some bugs in the emulator. - Started work on implementing the Super VIA emulation. - Added support for disabling disassembly per instruction, when in debug mode. - Did some more work on rewriting the SuB Suite to work with the new calling convention. - Rewrote the symbol handling code in the emulator's assembler, to make it both simpler, and to add support for arbitrarily deep symbol scopes. - Added support for arbitrarily deep local symbol scopes. For example, to declare a symbol of depth 2, you add two '@' characters to the start of the symbol name. In other words, the number of '@' characters before the symbol name is what determines the scope of that symbol. And to use a symbol thats outside the current scope, you would use the same syntax as using a struct member, so you would do `global.local`. --- programs/sub-suite/shift_line.c | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) (limited to 'programs/sub-suite/shift_line.c') diff --git a/programs/sub-suite/shift_line.c b/programs/sub-suite/shift_line.c index 255d21b..365666b 100644 --- a/programs/sub-suite/shift_line.c +++ b/programs/sub-suite/shift_line.c @@ -24,6 +24,12 @@ uint8_t bitpos(unsigned int row, uint8_t *mask) { } +uint8_t getbit(unsigned int row, unsigned int offset) { + uint8_t mask; + uint8_t byte = bitpos(row+offset, &mask); + return (bitabl[byte] & mask); +} + void setbit(unsigned int row) { uint8_t mask; uint8_t byte = bitpos(row, &mask); @@ -48,7 +54,7 @@ void shift_line(char *str, int cursor, int left) { if (left) { int i = end-1; int j = end; - for (; i > cursor; i--, j--) { + for (; i >= cursor; i--, j--) { if (i < 0) { i = 0; str[i] = 0; @@ -72,7 +78,7 @@ void shift_line(char *str, int cursor, int left) { str[i] = 0; } end = find_end(str, i); - if ((end % maxcol) == 0 && (end/maxcol) > scr_row) { + if (((end-1) % maxcol) == 0 && ((end-1)/maxcol) > scr_row) { clrbit(end/maxcol); } } -- cgit v1.2.3-13-gbd6f
