Hi,
In C++ you can create a fixed array on stack:
int count = getCount();
int myarray[count];
In D the "count" is part of type and must be known at CT but
in example it is RT.
How to do such thing in D? Without using of heap.
You could try alloca:
import core.stdc.stdlib: alloca;
pragma(inline, true) auto stack(T, alias len)(void* p =
alloca(T.sizeof * len)) {
return (cast(T*) p)[0 .. len] = T.init;
}
void main() {
import std.stdio: writeln;
int size = 42;
auto a = stack!(int, size);
writeln(a);
a[] = 2;
writeln(a);
}
Thank you.
But this requires using of C function "alloca". I think this
cause some RT overhead (and in output asm code) in comparison
with C++ variant. Or I'm not right?

Where D is lacking is a good GUI editor and GUI library support. I am starting by building a python-based project called QDmt = Qt/D manager It will do for you, in a cross-platform way, the laborious task of compiling the Qt framework from git: https://wiki.qt.io/Building_Qt_5_from_Git And also it will guide you through building Qt Creator itself. We can then use this tool to help us hack the Qt Creator code and make it work for D (assuming a plugin isn't enough). Building Qt is quite essential, as I am unable to get OpenGL support without building it for example. So not only will we get traffic from TDPL people but from others who are only familiar with Qt and had to build it for some reason. This would then be the goto tool for that. Then they will see firsthand how easy it is (at the click of a few buttons) to work with D. This will cause a huge influx of users to dlang.org and a rift in the spacetime continuum! QtCreator 4.8.0 introduced support for the LSP last month : https://blog.qt.io/blog/2018/12/06/qt-creator-4-8-0-released I think I'm going to add it to the list of editors to look into and perhaps try to make a plugin for it.

nice-curses releases / dub version git?
Hey there D community! After a a bunch of years absence I'm getting back into D and its quite fun so far :-) I'm working on a little project that is uses nice-curses and now I stumbled across a bug that makes building impossible on Windows for me. Luckily that was fixed 3 months ago, but the last nice-curses release is from 2017 :-( So here are my questions: 1. Are there any plans in terms of future releases of nice-curses? 2. Is there a way to get a certain git-version (eg. commit or maybe even just "latest") for a package in dub? 3. How is everyone in general using curses with D? Is there maybe a different library I should checkout instead? Are you using latest git? Best regards, Droggl

[...] I tried using (n)curses in D before, but eventually opted for a D-specific solution: Adam Ruppe's terminal.d: https://github.com/adamdruppe/arsd/blob/master/terminal.d Fits much better with idiomatic D, and has served me very well since.

It's more likely that someone comes along with a new general purpose library which hasn't seen much usage and thus can define slightly better names.
