Yes, but you are proposing to port library from language which does not have them.

Good GUI (or any other library) for D without 'manual'
translation of code is just impossible.
Practically when I was porting mine I did cut n paste
from Java with code inspection with D in mind.
Code inspection process happens in lifecycle of any
project.
D is close enough to Java / C++ to make it happen
mor or less flawlessly. And I am not sure what
source language will be used as a source of porting:
C/C++ or Java more.
The most serious project I am getting these days is
to port some GUI project from C# :))

Java, is a server side platform these days.
In big picture GUI in Java is exotic rather than practical.

But structs can't have ctors, which reduces their utility IMO.  The alternative is using classes with alloca, but I don't see that as a particularly attractive solution.  In some respects it might be nice to have a language mechanism to allocate classes on the stack:

Class C {}
C c = local C(...);

But sadly, this still doesn't support copy semantics, which is a limiting aspect of classes with alloca.  Personally, I find this issue to be the most difficult adjustment in moving from C++.  There, explicit dynamic allocations are a design choice and happen quite rarely, while in D they're both unavoidable and quite common.

I am trying to help. I am trying to allude that it is good to build walls first and only then "opening the doors" for anybody.

First: I've asked you and Walter many times here to
show real Java GUI application except of Eclipse.
SWT? Fine! But show please applications made on
this platform. Without, talks about porting
Java code and huge opportunities and doors in this area
are just one big puff.

Second: please, don't think that I am propaganding
Harmonia. I've told many times:
Harmonia is not for everyone and every GUI task.
It should be a set of DFL alike toolkits highly
optimized for particular platforms.
Just visit WTL news groups to get an idea what
is going on and how native GUI packages are popular.

Kris, please trust me, I am in GUI business all my life.
Java GUI dead now. Eclipse alone is just nothing if
you'll compare it with full rainbow:
http://www.atai.org/guitool/

And there is a huge crowd of people who are looking
for client side programming solutions now. The biggest
stream now is not coming from Java but suprisingly
from C# and C++.
'cause WinForms.NET failed and real Avalon GUI
will appear alive in 2011 or so.

Andrew, I really wish I could understand what it is you want me to do (or not do). I would avoid replying, but I don't wish you to feel your perspective is being ignored. So ...

Walls? I thought you said it was Walter's time-management you had a beef with? Now I'm really confused.

Why should anyone show any application at all? I really don't see where that has any bearing whatsoever. What 'huge' opportunities?

I think you're blowing thing entirely out of proportion here. It's really simple Andrew: a number of folks feel it's worthwhile porting some Java code over to D. End of story. Nobody's asking you to do the work, although you're very welcome to join in if you so desire.

What I've been working on is not intended for everyone or everything, either. But it does have native attributes.

Let me play all this back to you. You're saying: "Kris, I'm an expert in this field; don't waste your time and that of others; drop any ideas you have regarding a port of Java code to D. It's just not worth it. Trust me; I know what I'm taking about."

You may well be some kind of expert, Andrew. But you've yet to come up with even one solid reason why I, or anyone else, should buy in. Sure; you've said lots of things along the lines of "Java GUI dead now" or "SWT is failed design", but that is hardly concrete or convincing, and nor is it particularly relevant.

I'll be happy and willing to listen to you, if you can bring something more to the table than what appears to be wholly unfounded speculative assertion. It's not even clear what it is you wish me to do ... so you'll have to start there.

So ~ there's a bunch of C# and C++ developers looking for a language with a good GUI? For Windows? Cross-platform? OK.

I don't know if SWT is that bad. I don't know much about GUI libraries besides a handful of them. The same could be said for libraries in general. I understand (it's not hard to do ;)) that there're good and bad libraries everywhere, but I'm all for options.

Nobody can know before hand if porting some library (good or bad) to D will produce the same library as before: maybe it'll get better, or it could get worse, but it can only be known after it's been done and tested. So, Andrew, while I respect your opinion as much as I respect everyone else's, I think it's good that more libraries are ported to D. They can come from anywhere, they can be old or new, they can be anything related, but we, the D programmers, need those libraries, and only using them we'll know if we stick to them or not.

One example: I still think DFL is the best D GUI library right now, but I don't use it because it's Windows only. I follow it, but that's it. Portability is very high in my book, so I have to look somewhere else. But that's me, somebody else will think different, and that's where options come handy.

I think the worst mistake we as human beings can make is to think that we have to make everybody think like we do, think that there's only one absolute truth. "Only Sith(s?) think in absolutes" ;)

Seems indeed I want too much and went too far.
It is personal, terribly sorry.
I am forced to stop working on Harmonia today.
Three new projects requiring my full dedication.
And I cannot use D there. There were chances
but ... various reasons to be short.

Ok. Consider me and others as a C++ guys.
We are asking for const implementation. What
will benefit D more?
Answer from heavens is one: there will be inners
instead (but not finals). And nobody willing
to explain why? Just common words: there are
somewhere some Java projects which will be
translated automatically from Java...
I know Java. I did my own VM. I am not
buying this automatic translation.
Java is a platform. Code without platform -
system of classes from lang.java etc. -
is nothing.
Moreover I've provided concrete link which will help
to try this translation without need of inners.
So anyone who have project to port can use
this tool now. Just to test is it possible at all.

In GUI business absense of successfull applications during
5 years of development means two things:
either this technology was designed to accomplish one
particular task (SWT/Eclipse) either it is failed.
I don't know what to say more concret here.

Yep. This one second for me too (after const).

I hope it's temporary. Harmonia is very impressive.

Andrew...
*snip* I am forced to stop working on Harmonia today.

We all have our own ideas for D man, but patience is allot more useful than giving up. But, if you have other projects that need attention, I do wish you good luck with them.

Between this and TZ, I am starting to think that this is the Drama programming language... :) (c'mon, that's funny!)

I LOVE D!

Regarding a const implementation: I'm afraid you're just gonna' have to get over that, Andrew. I've been asking for a readonly modifier for about a year now, and there were probably others before me. This is not some kind of new request, by any stretch of the imagination. It'll happen when it happens.

I see.

So place a wager, then.

If you're so adament that it's simply not possible to port a major Java library to D without some serious hand-waving and serious manual intervention, then put some clout behind those claims of yours. Let's just see how much value all this expertise and knowledge of yours is really worth :-)
