That doesn't have anything to do with the server side if I am not 
mistaken as you should receive that via the browser that actually 
allows you to receive the mac address -via an extension- or some 
private API exposed by the browser.


I don't know the use case but you may be better off with browser 
fingerprinting if you'd like to have a unique way of identifying 
the visitors. Or, if it's a local network, maybe you can use 
tcpdump/libpcap.

if S2 consists of data for Layout struct, then you can simply do:

which will give you a range of Layout.

No it wouldn't be a big pain. There are many tools for 
automatically migrating issues from Bugzilla. The only thing 
depending on Bugzilla is the changelog generator, but it's API 
calls to Bugzilla can be replaced with GitHub API calls within 
an hour.
So the entire migration could be easily done in a lot less 
than a day.


The only reason we still use Bugzilla is that the core people 
are used to it. Here are a couple of the common arguments:


1) Bugzilla is our, we don't want to depend on GitHub

The D ecosystem already heavily depends on GitHub. Exporting 
the issues from GitHub would be easy. Besides there is only 
one person with access to the Bugzilla server.


2) GitHub only has per registry issues

Bugzilla uses components too, they don't support global issues 
either. Besides if that's required one could easily create a 
meta repository for such global tasks.


3) Bugzilla's issue tracker is more sophisticated

Sure, but does this help when you loose out on many 
contributors?
GitHub even has build tools and sites that let anyone discover 
"easy" issues if they are labeled accordingly. It's free 
marketing.


FYI I asked the same question 1 1/2 years ago: 
https://forum.dlang.org/post/ezldcjzpmsnxvvncn...@forum.dlang.org


Since then, for example, GitHub got voting for issues, but 
Bugzilla lost it.


I wholeheartedly agree. The customer is always right, 
especially when you're trying to get them to donate their time 
to an open source project. It's more essential than ever that 
we lower barriers to participation; if Github issues is the hip 
new thing all the kids like, then we need to switch to that. We 
shouldn't be constantly switching to the shiniest new toy, but 
nor should we stubbornly stick to a piece of software that was 
built (and it looks it) in '90s.


Or at least we should if we're trying to attract the kind of 
people for whom not using Github is a deal breaker. Older 
C++/Java programmers likely don't care, but younger 
Python/Ruby/JS users will.


there are three things that i've noticed:

- in this thread, there is not a single positive post by walter. 
none. nada. zilch. it'd have been much better if he just did not 
post anything.


- d leadership is dusty and so are their tools. we are no js 
community and hope we never become anything like them but 
bugzilla is a hundred years old. i am on github, i am on this ml 
and i also need a bugzilla account? what else do i need to be a

travel in between? have a forum software, allow me to sign in via

I tried it with a -version=CustomPath argument and inside the

yes, it is allocating memory. you can test such cases with @nogc

you can get a char[] via .dup of a string and then you can 
cast(string) if you don't want to allocate any memory.

hi aliak

since Point is a Tuple and does not have a constructor that takes 
a list of integers (int[]), you should have a helper function.


import std.stdio: writeln;
import std.string: split;
import std.algorithm: map;
import std.typecons: Tuple;
import std.conv: to;

alias Point = Tuple!(int, "x", int, "y");
enum data = "1,2:8,9";
alias makePoint = (auto ref points) => Point(points[0], 
points[1]);
alias convertToInt = (string parts) => 
parts.split(',').map!(to!int);
auto points = 
data.split(':').map!(convertToInt).map!(makePoint);


writeln(points);

impossible across separate forks/branches? What if I have

you can fork it, set dmd/master as upstream and then git fetch 
upstream. you can then rebase.




And how does a pull request actually work? Is it a request to 
merge my entire branch, or just some specific files? and do I 
need a separate branch for each pull request, or is the pull 
request itself somehow isolated from my changes?


commits can be cherrypick-ed or you can request your entire 
branch to be merged. it doesn't always have to be the master 
branch. for example, if there's std.experimental.logger branch, 
you can ask for your branch to be merged with that. having a 
seperate branch for each feature is most of the time the way to 
go. makes it cleaner for yourself. later on you can delete those 
merged branches.




Anyways, I'd just be rambling if I kept asking questions. If

would be really helpful if there are any Intellij users out

to the plugin so that if anything breaks it's easy to inform 
the team about the problem.


There is also support for debugging with GDB (since v1.14 1st 
Nov). We need to completely overhaul our documentation as some 
of it is outdated now and there is no mention of the gdb 
support. If anyone with Java/Kotlin experience wants to get

hi singingbush

i normally use emacs but i wanted to contribute to the community 
effort and see how the plugin is.


i downloaded IDEA CE 2017.2 and i have imported an existing D 
project. when i want to run the project it lets me choose if i 
want to use DUB or DMD (that's great) and then i choose DUB and 
then it warns me about project not having SDK settings. i then 
went on and set the DMD/bin path as the SDK folder.


i also set the DUB path initially but after running, it told me 
to configure it again. maybe it did not save in the first place.


all in all, it was a pleasure. thank you for your efforts :)

It seems that D still has the GC being mentioned up to today.

Maybe its better to move the standard library slower to a non

as a d user, i do not give a single flying fuck about manual 
memory management. i love gc. period. please let gc be my guest 
and clean up everything for me. i have other problems like d / 
dmd / phobos failing me on freebsd; vibe.d working amazing on 
linux and throwing some random shit on freebsd.


d is better than java, let alone c++. they both are crap. 
garbage. incredibly explicit and verbose. yet they get work done 
for other people. and these people, since the inception of d are 
throwing random arguments against d. they never ran out of 
arguments. it was two std libs, it was two d versions, it was 
lack of 3rd party libs, it was lack of giant corp support, it was 
lack of community / resources, it was and it will be something 
for those people. until they decide to shut the fuck up and 
actually give d a try. just like great people we get here 
everyday.


a big problem of d is that it is a play-dough for many people 
here. they don't run into problems with d because they are mostly 
not eating their own dog food or incredible experts at d. 
(remember qtd guys?) if we have 100 wtf moments per hour, they 
probably have like 1-2 per year. they do more abstract stuff 
rather than concrete stuff. (atila & co, manu, sociomantic 
people, jacob and some more are exceptions). they are blind to 
newcomer problems. they also have prejudices like assuming you 
know all the low level stuff beforehand.


when your beloved language (or its toolchain) screws things up 
for the app you wrote and deployed and will be used by millions 
of people per year, you have more problems than you imagined 
earlier and gc is not one of them.

This looks suspicious - it is a slice of the memory-mapped

how to build project with locally compiled phobos

[Mengu via Digitalmars-d-learn]

hi all

i've successfully compiled phobos master with gmake on freebsd. 
(make fails, i've no clue at all as to why)


how do i compile my project now against my local phobos with dub? 
with plain dmd?


i tried (in dub.sdl):
- full path to new libphobos.so with -defaultlib to dflags
- full path to new libphobos.so to lflags

i checked with ldd and saw the original libphobos.so was used. my 
current workaround is copying mine to /usr/lib.


thanks in advanced.

Interesting that it just straight up core dumps, usually you'll

see

Only other thing I can suggest is try linking against a debug

the latter is what i did. i re-compiled phobos master and used 
it. this time everything worked as expected.


btw, regex match happens in HTTP.Impl.onReceiveHeader. i think it

hi dominikus

you can call functions as func(arg) when compiler can infer the 
types for your functions but when it's not you'll get an "cannot 
deduce arguments" error.


when you call bar template function, you won't be able to modify 
the argument n. ++n will not work and will throw an error at 
compile time.


import std.traits : Unqual;
import std.stdio : writeln;

uint normalFoo(int n) {
++n;
return n;
}

uint constNormalFoo(const int n) {
++n; // will raise error
return n;
}

uint templateFoo(T)(Unqual!T n) {
++n;
return n;
}

uint constTemplateFoo(T)(const Unqual!T n) {
++n; // will raise error
return n;
}

void main() {
writeln(normalFoo(42));
// writeln(constNormalFoo(42));
writeln(templateFoo!int(42));
// writeln(constTemplateFoo!int(42));

}

So I'm into this platform with a vibe.d api server + back-end 
and I'm confused/curious to know the hosting package to use. I 
will have a lot of images uploaded by users.


1. For sometime, I've been looking at heroku which is fine with 
its load balancer, easily scaling etc. But the hosting cost for 
a startup is high and (most importantly) requires an external 
storage either s3 or cloudinary which no lib in D currently 
exist for them (stable).


2. Get an EC2 instance from Amazon or Vultr and install 
everything yourself and save images on disc (potentially 
problematic). This can not be scaled easily


3. use a self-hosted PaaS like Flynn (aka self hosted heroku) 
...but you still have to store images in an object storage and 
a D api is needed for this. Which links back to point 1 but 
less costly and more control.



How would you do it if you were using vibe.d?

(With node.js, all these are solved).


heroku is a bit more expensive. for starters, you could have a 
vps on digitalocean and let your application run on there.


google cloud is an excellent platform that i run my company on. 
it is a lot cheaper than aws.

A new 'type' named Body which IS-A std::string is defined.


i think we can mimic this with an alias this for a string (or 
const char*) property. is that right?



To construct a Body there are various options:
The ctors 'default': Body(), 'copy': Body(const Body&) and 
'move': Body(Body&&) ctors are using the compiler generated 
default implementation.

The same is true for the assignment operators =


how can i check what compiler generates for default so i can add 
them to my extern C++ clause?


Then a few explicit conversion ctors are defined to construct a 
Body from a const char* string and std::string. Explicit means 
the compiler is not allowed to implicit convert to std::string 
or const char* for provide args not being a const char* or 
std::string but for which a conversion exists.




i'll give these converters a try.


Since the h file also contains the definitions, the compiler 
must inline the code for the Body ctors and assignment 
operator. It also means not C/cpp file is needed since the 
function bodies are already in the h file.


i realized that when i saw the member initialization syntax in 
header files.

One way to do it, that might be a bit confusing, is to force 
the declaration of the function to explicitly specify a pointer 
or a reference. Currently it looks like it's an implicit 
pointer.


extern (C++) class Klass {}
void foo(Klass*); // ok
void foo(ref Klass); // ok
void foo(Klass); // error

Of course, there's always pragma(mangle) as well.

While I am getting errors loading images through glade's image:


(test.exe:8188): Gtk-WARNING **: Could not load

file 'test\a.jpg'


(loads fine in glade)

which needs to be resolved, I'd also like to be able to use 
gdkpixbuf to load images programmatically. There seems to be no 
demos on the gtkD github page that deals with image loading.


I've tried to do something like

import gtkc.gdkpixbuf;
auto x = c_gdk_pixbuf_get_formats().data;

but I don't know how to interpret x.

Also something like

import gtkc.gdkpixbuf;
void* x;
auto p = c_gdk_pixbuf_get_formats();
for(int i = 0; i < 10; i++)
{   
x = p.data;
p = p.next;
}

which doesn't offer any help.


Aside: How can we call the gtk functions directly using gtkD? 
Seems it uses stuff like


Linker.link(gdk_pixbuf_get_formats, "gdk_pixbuf_get_formats", 
LIBRARY_GDKPIXBUF);


It does seem to alias to these function but something is off 
and I'm not sure what.


hi

- is the gtk.Image class not working for you? 
https://api.gtkd.org/gtkd/gtk/Image.html


- there's also a gdkpixbuf.Pixbuf that you can use. 
https://api.gtkd.org/gtkd/gdkpixbuf/Pixbuf.html


- you can import those functions from gdkpixbuf.c.functions.
