hi!
i want to clarify some subjects...

1. if i am worried about internationalization, should i always use wchar (UTF-16) as java does? does all phobos libraries
    support wchar?

2. i don't understand the differences between a class and a struct. can anyone clarify? what are the overheads of using classes?

3. DTL when for?

4. DIDE is supposed to have a feature like MSVC intellisense?

5. I want a D GUI framework for windows... what's the best one?

best regards,
Miguel Simoes

It has a form of intellisense but (IMHO) not as good as VC, yet.  Hopefully Charles will figure out something really neat (he's told me he might re-work the intellisense stuff yet again).

A struct defines a fixed arrangement of data in memory.  A class's members can be arranged however the compiler sees fit.

Classes inherit from each other.  Structs don't.

Struct members are by default (always?) public.  Class members are by default private.

Structs are contained by value.  Classes are contained by reference.

Struct instances can be allocated on the heap, the stack or an externally managed area of memory.  Class instances are (nearly) always allocated on the heap.

> what are the overheads of using classes?

Apart from always allocating them on the heap, practically none.

Depends on what you want out of it.  They're all pretty much in early stages of development.

But do see my project SDWF:

Normally you'd use arrays of dchars (dchar[]) for keeping strings in
unicocde internally, or UTF-8 (char[]), which requires more processing
time but is compatible with standard C strings.

Structs are the same as in C basically (ie a memory block map) but in D they can have associated methods and such as well. Basically they cannot be subclassed, cannot inherit, and so on. They are useful when interoperating with C code.

There are a few floating around. You can program Win32 directly of course, but I'd agree that's not especially pleasant.

One subject per post please.

DTL is a secret project from Matthew, who knows...?
Now the guy is ill (seek?) what's going to happen?

intellisense is simple to implement.
Charles should be able to do it. He showed the interest on it.
'leds' intelisence is almost complete but has some bugs.
http://leds.sourceforge.net
Who want's to help porting leds to windows?
(can we convince Scintilla to compile in GTK mode in windows?)

Mine! http://dui.sourceforge.net

Am better, and back home in Oz.

Walter and I are working on various compiler/language aspects for DTL, so the "soon-ish" answer still holds. ;)

To be more definitive, I expect to have something useful/usable by 0.84, and a full-ish version by, say, 0.86

Can anyone compare DIG and DUI? is DUI available for windows? DUI does not depend on GTK version for windows? If it depends, isn't GTK for windows in early stages (full of bugs)?

I never looked deeply into DIG.
I see two main differences:

- DUI is portable for multiple platforms - DIG is not.
I'm yet to try compiling DUI with gdc (I just installed gdc)
but it's just a matter of time before he have it for any platform
supported by both gdc and GTK.

- DUI is based on a design well know and use by many - DIG is not (AFAIK).

if you are not concern with other platforms other then windows DIG might be a choice. The d-lab yahoo group is keeping DIG alive.

even if I give up on the DUI project I believe we will always have a GTK
bingind for D and that can't be very different from DUI.
(wouldn't it be nice if the gnome guys pick up D!?)

DUI is not yet complete and I can't find time for it
(at least for the last 3 or 4 months) I still want to finish it.
That should be easy now that I created some automatic wrapping
of the GTK prototype functions and docs.

>If it depends, isn't GTK for windows in early stages (full of bugs)?

from http://www.gtk.org/projects.html:
"GTK+ for Win32 - this backend is included in the regular GTK+ packages."
so it seems to have a quasi "official release" status.

from the http://www.gimp.org/~tml/gimp/win32/:
"The program(s) might crash unexpectedly or behave otherwise strangely. (But of
course, so do many commercial programs on Windows.) "

Ant

Ant avoids admitting some things. DUI always depends on GTK, on Windows as well as on Linux

> If it depends, isn't GTK for windows in early stages (full of bugs)?

No, it was in early stages many years ago. However, it seems to be particumarly slow on Windows - though it only shows on something like Pentium 166 MHz. Besides, tablet support is still broken.

The Windows version of GTK is not as perfect as Unix, but i'd say it's more worth fixing than avoiding GTK at all, because GTK is still the only powerful cross-platform and cross-language (very important!) GUI library out there.

What about wxWidgets?
