Hi,
I am still playing with DGUI library. Besides other things, I would like 
to convert enum names from 
"THIS_STUPID_NAMING_CONVENTION_WHICH_I_ABSOLUTELY_HATE" to "thisGoodOne".
Obviously I could do this by hand but it is a bit time consuming. Any 
tool / hack to help me with this?
Thank

Refactoring tools are not available for D as of yet. Your best bet is to  
use a bash command or your editor's Find & Replace in Files feature.

You mean at compile-time? Try this: http://dpaste.dzfl.pl/06b95c3f

Copied below:

import std.conv;
import std.string;
import std.traits;

private  property string toCamelCase(E)()
    if (is(E == enum))
{
    string result;
    result ~= "enum CamelCase {\n";
    foreach (Member; EnumMembers!E)
    {
        foreach (word; to!string(Member).split("_"))
        {
            result ~= word.capitalize;
        }
        result ~= " = " ~ Member.stringof ~ ",\n";
    }
    result ~= "}";
    return result;
}

template CamelCase(E)
    if (is(E == enum))
{
    mixin(toCamelCase!E);
}

enum SOME_ENUM
{
    VAL_FIRST = -4,
    VAL_SECOND
}

alias CamelCase!SOME_ENUM SomeEnum;

void main()
{
    SomeEnum en1 = SomeEnum.ValFirst;
    SOME_ENUM en2 = SOME_ENUM.VAL_FIRST;
    assert(en1 == en2);
}

Ah ok. Well it wouldn't be too difficult to write a small D script
that does this on source files. You wouldn't need a full-fledged
parser just to rename enums.

If you're on Windows and know Python, you could download Programmer's
Notepad 2 <http://www.pnotepad.org/> which supports scripting in
Python to make custom macros/tools/extensions/etc. Maybe someone
already made such a PN2 script, I don't know. It does already have a
built-in keyboard shortcut for "convert to lowercase" (ctrl-u), which
might at least help. Then you could manually uppercase the letter
after each _ and then regex search/replace to get rid of the _'s.

IIRC, Visual Studio has a similar scripting feature, but not in Python

Visual-D.

Or, it would probably be pretty simple to write a little script in D
that just does a regex search for say, `[A-Z_][A-Z_]+` and then
converts each instance.

Unfortunately I don't know offhand of a tool that would do it all
automatically without code needing to be written. :(

Blindly replacing identifiers is certainly not what I need, I want for 
example
FormStartPosition.CENTER_SCREEN to be written like 
FormStartPosition.centerScreen;
Enums in DGUI are written like
enum FormStartPosition {
   CENTER_SCREEN = SOME_WINDOWS_API_VALUE,
   ...
}
I need SOME_WINDOWS_API_VALUE unchanged. But it may be possible to do 
this with some script, I certainly check the notepad2.
