常见lua报错类型

类型1，索引nil值

1、attempt to index a nil value (global 'a')

    a.name = "haha"

2、attempt to index a nil value (field 'name')

    a.name.first = "haha"

3、attempt to perform arithmetic on a nil value (global 'a')

    a=nil

    print(a+1)

类型2，数学计算，逻辑运算中有nil值

4、attempt to perform arithmetic on a nil value (global 'a')

    a=nil

    print(a+1)

5、attempt to perform bitwise operation on a nil value (global 'a')

    a=nil

    print(a & 1)

6、attempt to perform arithmetic on a nil value (field 'b')

    a = {}

    print(a.b &1)

类型3、调用nil值

7、attempt to call a nil value (global 'a')

    a=nil

    a()

8、attempt to call a nil value (field 'b')

    a={}

    a.f()

类型4、数学计算、位运算中使用非数字类型

9、attempt to perform arithmetic on a string value (global 'a')

    a="str"

    print(a+1)

10、attempt to perform arithmetic on a table value (global 'a')

    a = {}

    print(a+1)

11、attempt to perform arithmetic on a string value (field 's')

    a = {s="str"}

    print(a.s + 1)

12、attempt to perform arithmetic on a table value (field 's')

    a = {s={}}

    print(a.s + 1)

类型5、数量限制

1、stack overflow (函数调用栈超限 LUAI_MAXSTACK 1000000)

    function a() b() end

    function b() a() end

    a()

2、upvalue数量限制

3、参数个数限制

4、局部变量个数限制

5、字符串拼接个数限制
