Generating enum class members with a macro

Question

I want to create an enum with 255 elements as follows:

enum class MyEnum
{
    Item0,
    Item1,

    //....

    Item254,
    Item255
};

Is there any way to generate the members of the enum using a macro instead of actually listing them all?

Answer 1

Well, it seems what the OP is after is BOOST_PP_ENUM_PARAMS . I won't say it's the best solution, but it does work for an enum with values like these:

enum class MyEnum {
    BOOST_PP_ENUM_PARAMS(256, Item)
};

Answer 2

您可能会使用Shell脚本来生成它们...我认为它们不会经常更改

echo Item{0..255},
