https://issues.dlang.org/show_bug.cgi?id=17542 Issue ID: 17542 Summary: DSON conversion of enums misses enum name Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: enhancement Priority: P1 Component: phobos Assignee: nobody puremagic.com Reporter: dlang-bugzilla thecybershadow.net This almost works: ///////////// test.d //////////// import std.conv : text; enum E { a } struct S { E e; } immutable S s1 = S.init; immutable S s2 = mixin(text(s1)); ///////////////////////////////// It doesn't work because for the enum member a, std.format emits just "a" instead of "E.a". std.format is already capable of converting the same type to string in different ways, e.g. format("%s", "hello") and format("%(%s%)", ["hello"]) will have the string converted differently (in the second case, with quotes and escapes). So, it would be nice that for similar circumstances, stringified enums had their name included in the same way that stringified structs have their name included. Incidentally, I found an interesting use case for DSON: parsing or generating a complicated data structure, dumping it to a .d file, then loading the .d file by using a mixin+import expression, for cases when generating said data directly at compile time would be too slow or otherwise impractical. --
