Feature request: add struct to save the original assigned value in each field about enum.hpp HOT 3 CLOSED

Hello!

Hm.. I'll try to impl it 👍

from enum.hpp.

I've just tried to make it in a branch (feature/value_string). But I have several issues now:

• external enums doesn't support;
• some ambiguities with "field_a | field_b" vs "field_a|field_b" and etc.

Due to these issues, I cannot add this to the main branch, but you can fork your own with these changes from the feature branch.

from enum.hpp.

Hi,

Thank you for such prompt reply! And I just checked the code, it is just what I needed.

In fact, I didn't envision a from_value_string method, for the exact reason that you just mentioned about ambiguity in the value string. I think it would be too much to try to come up with a good strategy to "normalize" the value string.

For my use case, I would like to rely on the value_string to provide some more verbose diagnostic messages for bit flags that are composed with multiple existing flags. A to_value_string method does the job perfectly.

Again, that you for the help!
