If the glib is so trivial, the implementing such structures again is also
trivial. Come on, I've done it dozens of times. I know what the effort is
and it's minor.

We're talking about the interface here. If you think glib should be allowed
internally, so should any other library that developers of this software want
to use that is licence compatible.

You just said that it's trivial to re-implement. I ran a system without
glib for quite some time to prove it was possible. Computing resources are
-very- important to our users, and your attitude is atrocious regarding this.
We spend very much time on optimisation. You either don't care about our own
human resources as long as it saves you perceived resources, or you see no
value in the work we do.

Great, so you accept that other options are also fair. Proposal: Qt based
libraries as part of the freedesktop spec. Oh doesn't sound so good anymore?

In the scope of KDE, I'll do everything I can. I am stuck maintaining the
crap in aRts now, full of STL, glib, and Qt. It's a nightmare. I am not
responsible for a single bit of it, but the developers have just written a
mess of code with those three libraries and then dumped it in CVS. I am sick
of maintaining this stuff and I basically convert what I can to Qt as I

Yes we are. The interface is about coding style, and coding style saves
-me- time. I am a user of this stuff. You want to save yourself 20 minutes
at the expense of 10 other people's 20 minutes each. Your desktop's X kb of
memory added vs all the other desktops X kb of memory added. How clever.

Not all developers agree that glib is clean or easy to maintain.

I argue that glib decreases the quality of code. Can you call me wrong?
No, you can disagree, that's all.

Considering we already link to several libraries that do these things.

Correct. You would not accept if I wrote such a library in Qt and required
every desktop to link in Qt, even if it was used internally only so GPL was
acceptable. Be honest.

No, I would personally rewrite them in the native toolkit in the case of
Qt. Time permitting. Shouldn't be hard, according to your statement above.
It just results in a fork. Fork at the beginning of the project, that's a
> I can't understand or agree with any of those points, sorry.
My views on this are clear, and I really don't intend to waste more time
arguing this. If you can't see that the purpose of something like
freedesktop is to provide standards, and secondarily implementations that all
desktops will want to use, then you are indeed missing the point. Declaring
standards seems to be a trend amongst certain organisations lately. Very
reminiscent of what people complain about Microsoft doing. At least some
groups have the choice to ignore the "standards" though. If you want
everyone to cooperate, you have to be sensitive to all of their views, all of
their requirements, and understanding of their points of view. I personally
want every desktop to be on an equal footing, and every user to be able to
choose which one he wants to use. Not everyone wants this it seems. The
most ironic trend in free software seems to be "free, as long as it agrees
with my point of view." I don't buy that. If it's free, I can choose to use
it or not to use it, or do something completely different. Since I am free
to choose, if you want me to use your stuff (do you even write any of this
personally?), you have to -convince- me. Convincing me, in this case, well I
have already outlined what I believe is fair to use. Otherwise I say fork
away. (Wow, I don't think I've ever heard of forking projects before they
are even released. That's a great sign.)
This thread is getting far out of control, and I have code to write. As I
said, my point of view should be perfectly clear. There's no point wasting
more time on this.
