Hi guys,I'm trying to read a string from a text file which contains a value of an enumeration like: enum MyEnum : string { Entry_1 = "abc", Entry_2 = "def", Entry_3 = "ghi", } Stream s = new File("myFile.ext", FileMode.In); uint len; s.read(len); string entry = cast(string) s.readString(len); s.close(); writeln(mixin("MyEnum." ~ entry)); myFile.ext may contain: ... Entry_2 Entry_1 Entry_2 Entry_3 ... But mixin's are for compile time only... is there any chance to do this or do I've to use another method (like if/else or switch/case): if (entry == "Entry_1") ... else if (entry == "Entry_2") ... ... Thanks a lot!
Metaprogramming is the keyword but you don't have to do it yourself. Just use std.conv.to!MyEnum(string_without_the prefix).
