轻量级的菜单系统，可移植性强

用c语言写的基于链表结构的多级菜单显示，菜单项目支持动态添加和删除，只要内存够用，理论上可以添加任意级菜单，类似于文件系统

menu.h

#include "stdio.h"
#include "stdlib.h"
#include "string.h"

        const typeof( ((type *)0)->member ) *__mptr = (ptr);    \
        (type *)( (char *)__mptr - offsetof(type,member) ); })

#define CURR_PTR " =>>"

typedef enum
{
    key_left = 0,
    key_right,
    key_up,
    key_down,
    key_enter,
    key_back,
    key_sum,
    key_none,

typedef struct displist_t
{
    int size;
    int cur_idx;
    endpot *cur;
    endpot *start;

typedef enum{

typedef enum

    dir,

typedef struct menu
{
    int idx;
    char name[30];
    char *bmp;
    void *arg;
    void (*func)(void *);
    void (*disp)(void *);

typedef struct node

typedef struct stack_node *PtrToNode;
typedef PtrToNode Stack;
Stack create_stack();
void push_stack(Stack s, unsigned long data);

最后添加一个小demo，demo.c

#include "myz_menu.h"
#include "stdio.h"
#include "stdlib.h"
#include "string.h"
#include "unistd.h"
#include <curses.h>

void quit_menu(void *arg)
{
    endwin();
    exit(1);
}

void printf_menu(void *arg)
{
    endwin();
    printf("hello world\n");
    sleep(1);
    exit(1);
}
void add_dir(void *arg)
{
    endpot *news = endpot_add(root.first, "new dir", dir, NULL, NULL);
}


void add_pot(void *arg)
{
    endpot *news = endpot_add(root.first, "new pot", pot, NULL, NULL);
    endpot_delete(root.first->next);
}

int main(int argc, char *argv[])
{
    pendpot file = ADD_DIR(&root, "file");
    pendpot edit = ADD_DIR(&root, "edit");
    pendpot select = ADD_DIR(&root, "select");
    pendpot view = ADD_DIR(&root, "view");
    pendpot gototo = ADD_DIR(&root, "goto");
    pendpot runs = ADD_DIR(&root, "runs");
    pendpot terml = ADD_DIR(&root, "terml");
    pendpot help = ADD_DIR(&root, "help");
    pendpot quit = ADD_POT(&root, "quit", quit_menu);
    pendpot new_file = ADD_DIR(file, "new file");
    pendpot open_file = ADD_DIR(file, "open file");
    pendpot closef = ADD_DIR(file, "closef");
    pendpot new_windows = ADD_DIR(file, "new_windows");
    pendpot open_windows = ADD_DIR(file, "open_windows");
    pendpot save_file = ADD_DIR(file, "save_file");
    pendpot save_all = ADD_DIR(file, "save_all");
    pendpot redo = ADD_DIR(edit, "redo");
    pendpot copy = ADD_DIR(edit, "copy");
    pendpot paste = ADD_DIR(edit, "paste");
    pendpot print = ADD_POT(edit, "print", printf_menu);
    pendpot add_p = ADD_POT(edit, "add a new pot", add_pot);
    pendpot add_d = ADD_POT(edit, "add a new dir", add_dir);
    pendpot s_all = ADD_DIR(select, "select all");
    pendpot us_all = ADD_DIR(select, "unselect all");
    pendpot repalce = ADD_DIR(select, "replace");
    pendpot aq = ADD_DIR(select, "problem");
    pendpot back = ADD_DIR(gototo, "back to");
    pendpot lunch = ADD_DIR(runs, "lunch");
    pendpot newterm = ADD_DIR(terml, "new term");
    pendpot closterm = ADD_DIR(terml, "close term");
    pendpot welcom = ADD_DIR(help, "welcome use");
    pendpot doc = ADD_DIR(help, "document");
#ifdef DISPLAY_C
    initscr();
    noecho();
    move(LINES / 2, COLS / 2);
    scroll(stdscr);
    box(stdscr, '*', '#');
    keypad(stdscr, TRUE);
    addstr("START MENU DEMO");
    move(LINES / 2 + 1, COLS / 2);
    int st = baudrate();
    mvprintw(LINES / 2 + 1, COLS / 2, "SPEED = %d BPS", st);
    refresh();
    sleep(1);
#endif
    menu_run(file);
#ifdef DISPLAY_C
    endwin();
#endif
}

linux上编译的时候需要提前安装curses



可以通过按动键盘上的 a,s,d,w,q,r控制菜单的跳转和执行
