can we use D to programming ESP32?
hi there, Does anyone know what's D's status for ESP32? I just getting started a few days programming with ESP32, and found the official esp-idf SDK even get CPP enabled by default, and this makes the HelloWorld app used 160KB of flash. What I want to talk is that ESP32 might be a powerful Embedded Controller for running D. And It seems that gcc already support Xtensa arch, maybe gdc works with ESP32. thanks! -- binghoo dang
Alias function with arguments
Is it possible to alias a function and its arguments, but for
that function to only be evaluated when the alias is used? For
example
alias pragma(inline, true) inline
inline
void func(){}
Re: LDC won't find ld linker -why?

Testing it, it will make the object file out of a hello world application, but then complain: ``` collect2: fatal error: cannot find ‘ld’ compilation terminated. ``` Run LDC with "-v" and check what the linker command is (somewhere at the bottom, LDC invokes `gcc` for linking). You might see something like `-Wl,-fuse-ld=...` in that gcc command line. Perhaps that ld.gold / ld.bfd is not installed and thus GCC complains that it cannot find it.

Essentially, it's ListStore basics leading up to how this type of model is used with a TreeView. You can find it here: https://gtkdcoding.com/2019/07/09/0051-mvc-iv-combobox-text.html Great work! I see this series of tutorial becoming a book for gtkd. Is it possible to get all the tutorials in a pdf file for offline work? Thanks in advance
"lld-link: error: could not open libcmt.lib: no such file or directory"
hi all! after a long while away, i thought i'd download the latest D release and give learning it another shot. unfortunately, it looks like i screwed up somewhere big time =[ it was working fine for me before [a few months ago i think], but now whenever i try to compile i get the message "lld-link: error: could not open libcmt.lib: no such file or directory". sometimes, depending on what i'm trying to compile, it complains it can't find "OLDNAMES.lib" as well. i thought it was just that i had installed D wrong at first, but i've uninstalled / reinstalled a dozen times now and it's still not working. could i really have deleted whatever it's looking for somehow? i really want to be able to program in D, but i'm at my wit's end... please help! =[ - moth
Re: Is there any way to define an interface that can implicitly convert to Object?

Is there a way to declare an interface as explicitly not a COM

everywhere is annoying.
Hi, not tested extensively but :
---
interface Foo
{
final Object asObject()
{
return cast(Object) this;
}
alias asObject this;
}
class Bar : Foo
{
}
void main(string[] args)
{
Foo foo = new Bar;
Object o = foo;
writeln(o);
}
