From 25f7d7952a5d3cde833cdbba7a45b1c4c5038364 Mon Sep 17 00:00:00 2001 From: Curtis McEnroe Date: Mon, 22 Jan 2018 04:48:48 -0500 Subject: Add klon I've been working on this the past two days. Not playable yet but I think a good start. I enjoy the card and stack representation too much and this is probably why I don't enjoy industry programming as much. --- bin/.gitignore | 1 + bin/Makefile | 2 +- bin/klon.c | 264 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 266 insertions(+), 1 deletion(-) create mode 100644 bin/klon.c diff --git a/bin/.gitignore b/bin/.gitignore index 8960977b..4b8dd9b2 100644 --- a/bin/.gitignore +++ b/bin/.gitignore @@ -3,6 +3,7 @@ bri dtch hnel jrp +klon pbcopy pbd pbpaste diff --git a/bin/Makefile b/bin/Makefile index f2112e29..a304c4cd 100644 --- a/bin/Makefile +++ b/bin/Makefile @@ -1,4 +1,4 @@ -BINS = atch bri dtch hnel jrp pbcopy pbd pbpaste typo wake watch xx +BINS = atch bri dtch hnel jrp klon pbcopy pbd pbpaste typo wake watch xx CFLAGS += -Wall -Wextra -Wpedantic LDLIBS = -lcurses -ledit -lutil diff --git a/bin/klon.c b/bin/klon.c new file mode 100644 index 00000000..a7ef014e --- /dev/null +++ b/bin/klon.c @@ -0,0 +1,264 @@ +#include +#include +#include +#include +#include +#include +#include +#include + +#define MASK_RANK (0x0F) +#define MASK_SUIT (0x30) +#define MASK_COLOR (0x10) +#define MASK_UP (0x40) +#define MASK_SELECT (0x80) + +#define SUIT_CLUB (0x00) +#define SUIT_DIAMOND (0x10) +#define SUIT_SPADE (0x20) +#define SUIT_HEART (0x30) + +struct Stack { + uint8_t data[52]; + uint8_t index; +}; +#define EMPTY { .data = {0}, .index = 52 } + +static void push(struct Stack *stack, uint8_t value) { + assert(stack->index > 0); + stack->data[--stack->index] = value; +} + +static uint8_t pop(struct Stack *stack) { + assert(stack->index < 52); + return stack->data[stack->index++]; +} + +static uint8_t get(const struct Stack *stack, uint8_t i) { + if (stack->index + i > 51) return 0; + return stack->data[stack->index + i]; +} + +static uint8_t len(const struct Stack *stack) { + return 52 - stack->index; +} + +static struct { + struct Stack stock; + struct Stack waste; + struct Stack found[4]; + struct Stack table[7]; +} snap, g = { + .stock = { + .data = { + 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, + 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, + 0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17, + 0x18, 0x19, 0x1A, 0x1B, 0x1C, 0x1D, + 0x21, 0x22, 0x23, 0x24, 0x25, 0x26, 0x27, + 0x28, 0x29, 0x2A, 0x2B, 0x2C, 0x2D, + 0x31, 0x32, 0x33, 0x34, 0x35, 0x36, 0x37, + 0x38, 0x39, 0x3A, 0x3B, 0x3C, 0x3D, + }, + .index = 0, + }, + .waste = EMPTY, + .found = { EMPTY, EMPTY, EMPTY }, + .table = { + EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY + }, +}; + +static void snapshot(void) { + memcpy(&snap, &g, sizeof(g)); +} + +static void undo(void) { + memcpy(&g, &snap, sizeof(g)); +} + +static void shuffle(void) { + for (int i = 51; i > 0; --i) { + int j = arc4random_uniform(i + 1); + uint8_t x = g.stock.data[i]; + g.stock.data[i] = g.stock.data[j]; + g.stock.data[j] = x; + } +} + +static void deal(void) { + for (int i = 0; i < 7; ++i) { + for (int j = i; j < 7; ++j) { + push(&g.table[j], pop(&g.stock)); + } + } +} + +static void reveal(void) { + for (int i = 0; i < 7; ++i) { + if (get(&g.table[i], 0)) { + push(&g.table[i], pop(&g.table[i]) | MASK_UP); + } + } +} + +static void draw(void) { + if (get(&g.stock, 0)) push(&g.waste, pop(&g.stock) | MASK_UP); + if (get(&g.stock, 0)) push(&g.waste, pop(&g.stock) | MASK_UP); + if (get(&g.stock, 0)) push(&g.waste, pop(&g.stock) | MASK_UP); +} + +static void wasted(void) { + for (int i = g.waste.index; i < 52; ++i) { + push(&g.stock, pop(&g.waste) & ~MASK_UP); + } +} + +static bool validFound(const struct Stack *found, uint8_t card) { + if (!get(found, 0)) return true; + if ((card & MASK_SUIT) != (get(found, 0) & MASK_SUIT)) return false; + return (card & MASK_RANK) == (get(found, 0) & MASK_RANK) + 1; +} + +static bool validTable(const struct Stack *table, uint8_t card) { + if (!get(table, 0)) return (card & MASK_RANK) == 13; + if ((card & MASK_COLOR) != (get(table, 0) & MASK_COLOR)) return false; + return (card & MASK_RANK) == (get(table, 0) & MASK_RANK) - 1; +} + +enum { + PAIR_EMPTY = 1, + PAIR_BACK, + PAIR_BLACK, + PAIR_RED, +}; + +static void curse(void) { + setlocale(LC_CTYPE, ""); + + initscr(); + cbreak(); + noecho(); + keypad(stdscr, true); + set_escdelay(100); + curs_set(0); + + start_color(); + assume_default_colors(-1, -1); + init_pair(PAIR_EMPTY, COLOR_WHITE, COLOR_BLACK); + init_pair(PAIR_BACK, COLOR_WHITE, COLOR_BLUE); + init_pair(PAIR_BLACK, COLOR_BLACK, COLOR_WHITE); + init_pair(PAIR_RED, COLOR_RED, COLOR_WHITE); +} + +static const char rank[] = "\0A23456789TJQK"; +static const char *suit[] = { + [SUIT_HEART] = "♥", + [SUIT_CLUB] = "♣", + [SUIT_DIAMOND] = "♦", + [SUIT_SPADE] = "♠", +}; + +static void renderCard(int y, int x, uint8_t card) { + if (card & MASK_UP) { + bkgdset( + COLOR_PAIR(card & MASK_COLOR ?
