Hi!
I'm having some troubles with an enum with base type string.
Here's the code:

enum Type:string
{
	DOT="DOT",
	ID="ID",
	MODULE="MODULE",
	SEMICOLON="SEMICOLON",
	ERROR="ERROR",
	EOF="EOF"
}

For every element of the enum, dmd writes this message two times:
 Integer constant expression expected instead of "DOT"
(with "ID", "MODULE", ... instead of "DOT")

Am I doing something wrong?

Thanks in advance.

I can't help too much with your problem because I tried it and it works for me (on my dmd 2.061), but the pattern you're doing there is actually unneeded:

enum Type {
   DOT, ID, MODULE, /* etc ....*/
}

would actually work and you can get a string out of it with std.conv.to:

import std.conv;

Type t = Type.DOT;

string s = to!string(t);

assert(s == "DOT");

Works fine for me with dmd >= 2.062

I'm using dmd 2.059. Maybe I will update it.
I'm using MonoDevelop as IDE.

I found that if I try to make an enum of doubles, dmd outputs 36 very complex error messages. I will try to investigate further.

That works too. Tried with 2.063-devel-f6d55a9-dirty:

enum Type : double
{
    a = 1.5,
    b = 2.5
}

void main()
{
    auto e = Type.min;
}
