You can create easy GUI using Qt or Win32Api.

I pretty sure I watched them on Youtube sometime ago, but I can't find

By the way, I'm looking from one video where someone shows some "C

I think it was the second talk in this list:

Any idea?

I am still not sure I have truly come to terms with the whole Rc/Arc
and RefCell stuff. It isn't so much the using them, it is trying to
decide what is the right combination for a given situation.

Big D win here due to garbage collection.

follow up question, if i allocate way more space for a bunch of

It looks like it will allocate all.

How do you call dub test causing the issue? Maybe there is a 
difference in the configuration/build type.


Also a side remark. You cannot use the output of dmd when 
colouring is on. Dmd lies because the backticks used for 
colouring are not shown. But without them, regex search is 
failing.


I also wonder whether dub Dustmite should be enhanced to search 
for a plain text too. Because while using regex search there 
might be characters which have a regex meaning while user just 
want a simple text search. This could also cause issues.


Kind regards
Andre

I have had zero luck with dustmite via dub. I would honestly 
recommend that you create a shell script that does `dub test 2>&1 
| grep "never matches"`, and just use that as a tester with 
dustmite directly.

What a pity! If Dlang have $ to indicate end of string. I think 
that is good some keyword to indicate the string itself.

@Basile B., thanks for the suggestion. I'll try this library

Just a bit of confirmation: I am a fan of D and GtkD for 
desktop UI work.


GTK+ is just a UI framework unlike Qt (which is UI and 
networking,
database, etc.) and is fairly straightforward to work with 
after the
initial learning hump – which is the same between GTK+ and Qt. 
Qt is
really C++ and Python only though many languages have bindings 
to QML.
GTK+ has many bindings, C++, Go, Rust, and D to name just the 
obvious
native code languages. C++ (gtkmm) and Go (gotk3) bindings are 
manuals
ones, Rust (gtk-rs) and D (GtkD) bindings are generated from 
the API
specification (GIR files). I believe this makes gtk-rs and GtkD 
far

superior to gtkmm and gotk3.

I have done a number of projects in Rust/gtk-rs and D/GtkD. 
Overall I prefer the code of D/GtkD over Rust/gtk-rs *but* 
there is much more IDE and editor support for Rust compared to 
D. This makes Rust code easier to write than the equivalent  D 
code, even if that Rust code is more ugly than the equivalent D 
code.


So whilst I keep wanting to do D/GtkD, I keep getting pulled to 
Rust/gtk-rs simply because CLion (and Emacs) support for Rust 
is so much nicer than the D support.


I must laud Samael's efforts on the IntelliJ IDEA/CLion D 
support, it is magnificent, but the project needs more resource 
to get the CLion D plugin somewhere near as good as the Rust 
CLion plugin. I am sure VisualStudio fans, indeed any other IDE 
users, will say the same about their IDE, I am a CLion user so 
try to push CLion support.


Just curious, how do you handle the whole RC> story in 
Gtk-rs?


For me it made the point that languages with tracing GC or 
implicit reference counting are much better solution for doing 
GUI programming.
