测试windows ini API 确定ini文件的文法

标题INI 的文法分析

ini 文件格式因为比较古老，网上也找不到具体的资料，只能找到例子，为了将ini解析到哈希表中，哈希表是 map>（C++语言），研究了一下它的语法。

ini 包含的字符

[ ] = ; ‘’ “”
[ ] 是在section中使用， = 是在赋值中使用，";" 是在注解中使用,‘’ 在值中使用,"" 也是在值中使用.

ini结构

[section]
app1 = value1
app2 = value2
…
[section1]
…
…
…
表(1)
根据微软的API描述 ini 的构造如表(1)

现在我们要研究一下 “section " 的格式是什么样的
先将结论写下：
在 section中前面空格和后面空格都会被修剪掉，夹在文字中的空格保留。
在其中 [ ]都可以使用
app 不以 ; 开始，不以 =或换行结束的任何串
value
支持十进制比如 1234
支持八进制比如 0o100
支持二进制比如 0b100
支持十六进制比如 0x64
支持串,取从=往后换行前的所有字符，不以‘’或”" 封闭的、以换行结尾，取其值,并将前空格尾空格剪裁掉，不以‘’ 封闭的、以换行结尾，取其值
注：十六进制不能用 0X 八进制不能用 0O 二进制不能用 0B 开始
中间没有 = 部分的行会被自动过滤，可以使用这种规则，加入自己的注解

C++ 例子：

#include 
#include 
void test_ini(const char* section_name)
{
    const char * INI_PATH = "E:\develop\cpp\ini序列化工具\ini序列化工具\test.ini";
    char hello[32]={};
    int num;
    int age;
    int one_23;
    int xx_xx;
    int num1;
    int num2;
    int num3;
    int num4;
    int num5;
    int num6;
    int num7;
    int num8;

    char welcome[32] = {};
    char test[32] = {};
    char test1[32] = {};
    char test_key[64]={};
    num = GetPrivateProfileIntA(section_name,"num",0,INI_PATH);
    printf("num=%dn",num);
    age = GetPrivateProfileIntA(section_name,"age",0,INI_PATH);
    printf("age=%dn",age);
    one_23 = GetPrivateProfileIntA(section_name,"123",0,INI_PATH);
    printf("123=%dn",one_23);

    num1 = GetPrivateProfileIntA(section_name,"num1",0,INI_PATH);
    printf("num1=%dn",num1);
    num2 = GetPrivateProfileIntA(section_name,"num2",0,INI_PATH);
    printf("num2=%dn",num2);
    num3 = GetPrivateProfileIntA(section_name,"num3",0,INI_PATH);
    printf("num3=%dn",num3);

    printf("num4=%dn",num4);
    num5 = GetPrivateProfileIntA(section_name,"num5",0,INI_PATH);
    printf("num5=%dn",num5);
    num6 = GetPrivateProfileIntA(section_name,"num6",0,INI_PATH);
    printf("num6=%dn",num6);
    num7 = GetPrivateProfileIntA(section_name,"num7",0,INI_PATH);
    printf("num7=%dn",num7);
    num8 = GetPrivateProfileIntA(section_name,"num8",0,INI_PATH);
    printf("num8=%dn",num8);

    GetPrivateProfileStringA(section_name,"hello","hello",hello,ARRAYSIZE(hello),INI_PATH);
    printf("hello=%sn",hello);
    GetPrivateProfileStringA(section_name,"welcome","welcome",welcome,ARRAYSIZE(welcome),INI_PATH);
    printf("welcome=%sn",welcome);
    GetPrivateProfileStringA(section_name,"test","test",test,ARRAYSIZE(test),INI_PATH);
    printf("test=%sn",test);
    GetPrivateProfileStringA(section_name,"test1","test1",test1,ARRAYSIZE(test1),INI_PATH);
    printf("test1=%sn",test1);
    GetPrivateProfileStringA(section_name,""测试key"","test_key",test_key,ARRAYSIZE(test_key),INI_PATH);
    printf(""测试key"=%sn",test_key);
    GetPrivateProfileStringA(section_name,"测试key","test_key",test_key,ARRAYSIZE(test_key),INI_PATH);
    printf("测试key=%sn",test_key);
    GetPrivateProfileStringA(section_name,"测试等号","test_key",test_key,ARRAYSIZE(test_key),INI_PATH);
    printf("测试等号=%sn",test_key);
    GetPrivateProfileStringA(section_name,";测试分号","test_key",test_key,ARRAYSIZE(test_key),INI_PATH);
    printf(";测试分号=%sn",test_key);
    GetPrivateProfileStringA(section_name,"#测试#","test_key",test_key,ARRAYSIZE(test_key),INI_PATH);
    printf("#测试#=%sn",test_key);
    GetPrivateProfileStringA(section_name,"string","string",test_key,ARRAYSIZE(test_key),INI_PATH);
    printf("string=%sn",test_key);
    GetPrivateProfileStringA(section_name,"string1","string1",test_key,ARRAYSIZE(test_key),INI_PATH);
    printf("string1=%sn",test_key);

}
int main(int argc,char** argv)
{
    test_ini("app");
    printf("1n");
    test_ini(""app"");
    printf("2n");
    test_ini(""[app]"");
