If you program more than one hour in D, do not watch it, but if you just found about D, feel free to check it out. It is not too short, and unscripted, but should give general feel of D, its power, major features (with some live coding, and exploration of various aspects in real world, including debugging), maybe for people who just want to see what it is about. And high level overview of the project and features. https://www.youtube.com/watch?v=_7Xg-E0NoNU While I am not great at making videos, I think it is good to promote D any way possible, as it can compete in many places, like Python, Julia, Zig, but people rarely hear about D lang these days.

So the fact that they don't... is effecting everyone in a negative way (also those that har happy with the runtime). I must be in the minority here because one of the reasons why I started using D was precisely because it HAS a GC with full support. I wouldn't even have considered it if it hadn't. For what I usually do (non-critical server-side unattended processing) latency is most obviously not an issue, and I for me not having to worry about memory management and being able to focus on the task at hand is a requirement. 1). You're not a minority at all. System programming is also vast so having a GC (especially D's special kind of GC) is nothing alien in System programming. If you look out there, you'd see most of the very important software (for the lack of a better word) written uses some form of GC. 2). I'm not sure anyone really know how many people use D, stay with D after first encounter or leave. So we're all guessing our biases. And I wouldn't look at just the core language as why someone will move to D or not. From my experiencing freelancing, I've come to see that a large portion of clients' decision stems from other things like familiarity and ecosystem (packages, frameworks, vendor/cloud support, engineering hiring pool, consultants/support availability, tooling, marketing/popularity/fomo/community, etc)... including things that usually comes from the community and stakeholders. For D we don't really have any measure of community size. Only looking at the forum can be misleading. 3). Using GC doesn't mean you're writing scripts. A significant amonnt of very large D code I've read (including those from long time users) use GC... sometimes partially. So to think or assume GC is hurting D is an unmeasured bias. I'm not saying those who are looking for nogc don't really matter (even though I hold the opinion that one can write nogc code in D just fine). dplug is written in D. What else couldn't? Also maybe the GC and other complaints (genuine or not), which I'm also a culprit, might actually be a contributing to people's first impression of D when they visit the forums. I have a strongly suspicious of this.

If you read the Origin of D book, you would see that the GC was a desire thing when D was designed probably due to how useful it is for ... as said, 90% or so of software development. So at this point, fighting the GC isn't (in my opinion) the right strategy. I should also say that I notice your point about improving GC in D and making it more optional as much as possible for things that still rely on GC...ARC, etc. The OP was about why programmers don't "like" GC. I've been here long enough to see the GC being one of the most re-occurring issues for discussion (probably due to new users coming in). There's been official posts about how D's style of GC isn't like that of fully managed languages, how to write nogc code in D, how to minimize GC, among others. Now if none of these work for you (for some special reason), then the long-term strategy might be an alternative runtime and or std. Which isn't a good answer that thought was worth it...so I didn't include that. If none of these work, then I (as in my personal opinion), don't know what else is available.

So "match and mix" basically means use it for prototyping, but do-not-rely-on-it-if-you-can-avoid-it. Switching to ARC looks more attractive, scales better and the overhead is more evenly distributed. But it probably won't happen.

Well, at least that is what I think is happening. If you want a few seconds (I think 5 or so), then you won't get these. It would be good if vibe-d could provide a way to shut down any keepalive connections when the server is shutting down. -Steve That's interesting. I actually started to dive deeper into those and tried to pinpoint the lines of code that result in additional open sockets upon new http connections; although my understanding of vibe-d is a bit too low at this point to figure out what's exactly happening. I think from a user perspective having something a bit friendlier on warning side would be helpful. Bausshf built a wrapper around vibe.d sockets called cheetah. Haven't used it myself but it looks more abstracted than than actual vibe.d code. Can't speak of the quality since I haven't used it myself.

Still not low-level though. https://github.com/bausshf/cheetah/wiki/Simple-Socket-Server-Example I've used the very vibe.d example you referenced in the past and didn't have any trouble with it.

Hello
I am trying to use this example for a iot application:
https://aberba.com/2018/using-vibe-d-web-interface/
The code i use is:
ushort port = 5504;
void main(char[][] args)
{
auto router = new URLRouter;
router.post("/archive", );
router.get("/archive", );
auto settings = new HTTPServerSettings;
settings.port = port;
settings.bindAddresses = ["::1", "0.0.0.0"];
listenHTTP(settings, router);
runApplication();
}
This is fine. But now that we have ~ 100 IoT devices in the
field, I would like to assign each a new port.
Why? I do not see any reason for that.
to separate the messages from the IoT responses quickly and
forward them to different programs, and to have the capability
in hand, so that when later i have an idea to exploit the
capability, I can also do it.
What you are doing, if I understand you well, is a way of scaling
the server to handle high amount of traffic.
If that's right, then I'm not sure how the number of PORT is the
issue. Irrespective of the port, the server resources remains the
same.
And if that's the case, then you might need a load balancer (or
use nginx or any of the options I've used in my projects). In
that case, you run multiple versions of the server in stateless
environments... scaled up or down on demand.
Been a long while since I wrote some vibe.d tutorials though :)

Its like laravel in php whilst vibe.d feels more like express in nodejs. Infact I believe Sonke wrote vibe.d after using express or similar framework by design. And yes, almost all frameworks work in a certain way. Arsd cgi.d might be what you want if you want to it your way as its more low-level interface-wise. I personally (and many others in the industry... judging by popularity of express (node.js) and the plentiful third-party libraries,..do prefer the router.get() design. Also having everything abstracted in a convenient and consistent way...is very desirable. vibe.d's web interface API is something I've always praised and thanks to how powerful D is compare to say JavaScript. Diet templates is also an example. However that power is not tapped in enough (yet) to favour using D conveniently over node (js). And web developers are interested in getting things done (at least my kind of web devs) rather than getting it our way...or squeezing every bit of efficiency out of it. Part of why v8 is fast by default (for us). Unike express (which is a thing layer with interface for third-parties to hook in and extend with libs), vibe.d became a monolith with everything included... making it harder to maintain and extend in other ways. Plus too much hard-coding by default currently. Unfortunately Sonke doesn't work on it like he used to...and its quite an huge accomplishment...the work he's done for D. I wish vibe.d could be positioned and sponsored officially or by community cus its the killer app. Staying lean and being extensible will open up for more innovation around it. Eg. a form handler for files library that works like how Ikod suggested...a customizable stream. Unless you're doing usual routing and database things, using vibe.d for a full stack projects can lead to a dead end unless you're positioned to write your own stuff to supplement. Of course its only a matter of time before this change for the good. Personally I use vibe.d for basic side projects. Looking to use it more going forward. But that's how I see it.

it will be bound to the body data.
I'm not sure I understand how to do this and parser the files

So an HTTP request with form data will come in with the

The first time you access `files`, it processes the stream
data, and splits it into form data and file data, saves the
files, and then gives you back the file dictionary so you can
use them.
If instead, you access `bodyReader`, YOU get to process the
form data and file data.

Meh, this is D :) we should be able to just process the data
and do whatever we want with it. What I would like to see is
vibe provide the parsing of form data, and just give me the
data as it comes (kind of like a SAX parser). Maybe just a
property in the HTTPServerRequest that I can set that says
"use this callback when you get Form File data".
I've done this with my REST interface, though that's not
form data.
Can you share your code for this?
Heh, this is not form data, it's just file data, raw on the
stream. So I have a function like:
```
class FileRestImpl
{
@path(":cat/:id/:uuid/upload")
@getAuth
void postUpload(HTTPServerResponse res, string _cat, int
_id, string _uuid, InputStream stream, Nullable!string md5sum,
NRMAuthInfo _authInfo)
{
...
}
}
```
You can see, I take an InputStream as a parameter -- the data
comes in there. I just read it and save it to a file (in the
correct location) anyway, verifying the md5sum is valid.
-Steve
Not a reply to this post in particular but to all the ones I've
read so far.
If I understand correctly. Vibe parses the form data and writes
all files to disk. Where to ?
Can I configure it ? I don't want libraries to just write data
to my file systems without me setting this up. Nowhere did I
find this behavior described in the docs.
And if not, how is data processed with a 10mb file upload
followed by a few number fields ?
It needs to read all of the file data to get to the other data
fields, doesn't it ?
I'm sorry this is completely counter intuitive. I can
understand the memory/security risks and all but I have no
intention to hack, DOS or however else disrupt my private
server in my private network with garbage data. I just want to
get the data in a byte[].
That's what I was trying to answer. When Steve said meh, he
probably didn't get what I said. Probably its because of my typos.
This sort of convenience and productivity benefit is part of why
I use Node.Js in the job when I need to get things doneand
not D yet. There are several pieces and bits you can't write
yourself when working on projects.
In this case you want to get the file(s) in memory...in the form
of bytes (or buffer) and probably set a file size limit. Its all
doable through a library but such a library doesn't exist in D
yet. At least not that I know of.
Its why I mentioned that multer[1] in Node.Js able to do
that...hence the advantage. Its built for the express
framework...meaning such library can be built to work with
vibe.d. Not everything can be built into vibe.d..and I think
that'll even make it bloated for other uses case. Its need an
ecosystem of third-party libraries.
In the case of the vibe.d form, data and files are handled using
this implementation[2] so its a reference to such a form parser
implementation...with support for a storage parameter for either
a MemoryStore or SessionStore. Multer does it pretty cleanly.
1. Multer: https://www.npmjs.com/package/multer

I don't believe the temp file behavior is customizable as it is hardcoded here to write to a temporary file (which is called on form parsing): https://github.com/vibe-d/vibe.d/blob/ebebfa827f568cc9bced4bec2b66edc043a8adf7/inet/vibe/inet/webform.d#L311 However if you really wanted to (but I'd advise against it) you could parse the form data from the HTTPServerRequest.bodyReader yourself Yeah I think what he wants is a way to write the file into an in-memory buffer. This is especially necessary it some environments where you can write to disk at all. How that's done, even in node.js is to use a middleware for parsing library to parse the headers in such way. I often use multer (which is also based on busybody) to do that in nodejs. Unfortunately I haven't used D to that extent to need such a thing... I in never hit that problem. I wonder if using a psuedo file handler will work for the in-memory buffer thing.

I believe there's a way to do that in vibe.d by using a program that monitors file changes but wasn't a low hanging fruit so I just recompiled manual.

You can call core.thread.thread_joinAll at the end of main.
So I tried that initially but my (){ writeln(...) } wasn't
printing anything in console. Could that be related to stdout

So I guess the error is elsewhere, but I'm not sure where and

Yeah, you're right. I changed receiveTimeout() to receive() to
try something and forgot to change it back.
Jeez, I hate myself.

So how can I now hide the core.thread.thread_joinAll so the

don't see how that can be done.

Another way would be to wait for a worker's exit by looking for
LinkTerminated but you need to start the thread with
spawnLinked:
Read that too, but doesn't seem like the desired behavior I want.
So here's the thing, unlike JavaScript, the D behavior seems to
be like a while(bool){} has to be placed directly within the
scope of main. Was thinking as long my while loop in
setInterval() was running, spawn() will be kept alive.
It seem both vibe.d and arsd have a similar setInterval()
implementation and they both require using their event loop to
keep the program alive.
In my case, wanted setInterval() to behave like it's own event
loop without placing it in a while(bool){} loop in main()

How to implement Canceleable spawn() from parent
Trying to implement a setInterval() that I can cancel using:
Tid tid = setInterval(2000, (){ writeln("hello");})
And then I can do:
stopInterval(tid);
With something like this:
stopInterval(Tid tid) {
send(tid, "cancel");
}
import std.stdio : writeln;
import std.concurrency : receive, spawn, thisTid, Tid;
auto setInterval(long milliseconds, void delegate() callback)
{
auto worker(long mls, void delegate() cb)
{
import core.thread.osthread : Thread;
import std.datetime : seconds, msecs;
writeln("Starting ", thisTid, "...");
bool done = false;
receive((string text) {
writeln("Received string: ", text);
done = true;
});
do
{
// or receive() comes here?
Thread.sleep(mls.msecs);
cb();
}
while (!done);
}
// I guess issue is with the callback
Tid id = spawn(, milliseconds, );
return id;
}
Getting error:
Error: template std.concurrency.spawn cannot deduce function from
argument types !()(void delegate(Tid id) @system, Tid),
candidates are:
/usr/include/dmd/phobos/std/concurrency.d(460,5):spawn(F,

Teoh wrote: On Wed, Jun 03, 2020 at 09:36:52AM +, drathier via Digitalmars-d-learn wrote: I'm wondering if there's a place that lists things which are slower/faster to compile? DMD is pretty famed for compiling quickly, but I'm not seeing particularly high speed at all, and I want to fix that. The two usual culprits are: - Recursive/chained templates - Excessive CTFE Note that while the current CTFE engine is slow, it's still reasonably fast for short computations. Just don't write nested loops or loops with a huge number of iterations inside your CTFE code, and you should be fine. And on that note, even running std.format with all of its complexity inside CTFE is reasonably fast, as long as you don't do it too often; so generally you won't see a problem here unless you have loop with too many iterations or too deeply-nested loops running in CTFE. Templates are generally reasonably OK, until you use too many recursive templates. Or if you chain too many of them together, like if you have excessively long UFCS chains with Phobos algorithms. Short chains are generally OK, but once they start getting long they will generate large symbols and large numbers of instantiations. Large symbols used to be a big problem, but ever since Rainer's fix they have generally been a lot tamer. But still, it's something to avoid unless you can't help it. Recursive templates are generally bad because they tend to produce a super-linear number of instantiations, which consume lots of compiler memory and also slow things down. Use too many of them, and things will quickly slow to a crawl. Worst is if you combine both deeply-nested templates and CTFE, like std.regex does. Similarly, std.format (which includes writefln & co) tends to add 1-2 seconds to compile time. Another is if you have an excessively long function body, IIRC there are some O(n^2) algorithms in the compiler w.r.t. the length of the function body. But I don't expect normal code to reach the point where this begins to matter; generally you won't run into this unless your code is *really* poorly written (like the entire application inside main()), or you're using excessive code generation (like the mixin of a huge procedurally generated string). Identifier lengths are generally no problem unless you're talking about 100KB-long identifiers, which used to be a problem until Rainer implemented backreferences in the mangling. But I don't expect normal code to generate symbols of this order of magnitude unless you're using excessively-long UFCS chains with nested templates. Identifier length generally doesn't even register on the radar unless they're ridiculously long, like tens or hundreds of KB long -- not something a human would type. What humans would consider a long identifier, like Java-style names that span 50 characters, are mere round-off error and probably don't even make a measurable difference. The problem really only begins to surface when you have 10,000 characters in your identifier or larger. Comments are not even a blip on the radar: lexing is the fastest part of the compilation process. Similarly, aliases are extremely cheap, it's not even on the radar. Delegates have only a runtime cost; they are similarly unnoticeably cheap during compilation. As are Variants, unless you're running Variants inside CTFE (which I don't think even works). T I'm thinking about a resource hub for D with information like these. Can I use this information? ...of course I'll reference this thread and you can always call for changes.

It seems the casual game community/fan is missing here.

Anyone recommend any specific tutorial/book? -Steve Over the years, I've seen so many 2d game frameworks/engine get started and abandoned here. I would recommend DSFML if you can get it to work. I really like the SFML API design. With that said, here are some I looked at: https://code.dlang.org/packages/d2dgame (based on SDL2 by WebFreak001, not sure how mature it is though, see a demo at https://github.com/WebFreak001/D2DGame/blob/master/example/source/app.d) https://code.dlang.org/packages/dagon (Mostly 3d, but can do 3d/2d games too. The most advanced of any D game engine/framework. Tonne of work poured into it) https://code.dlang.org/packages/pixelperfectengine (retro games, I have seen several YouTube demos by the dev) https://code.dlang.org/packages/godot-d (Godot is quite popular..used in commercial game. Not sure how good and easy to use this binding is though) https://themindofmurilomiranda.blogspot.com/2020/01/space-invaders-game-example-to-learn.html (Murilo Miranda has this tutorial he pulled together after working tirelessly and asking many question on using Adam's arsd package here, I like this guy's tenacity)

Any help/resources on that? Maybe you can use this dub package? http://code.dlang.org/packages/dgpio I'm using a D app on a raspberry Pi to open my house portal for 1 year now. It works perfectly. The "hardest" part is the compilation. I tried this guide yesterday: https://wiki.dlang.org/Programming_in_D_tutorial_on_Embedded_Linux_ARM_devices and it worked perfectly fine. I compiled my app from Windows with a Debian (from the windows store) and uploaded my executable compiled with ARM target. Thanks. Appreciate.

I tried reading up on dub, but got lost in the docs, so I really don't understand what all it can do. Dub is a tool for developers, I understand your requirements that you want target end customers of your applications. Therefore dub is the wrong tool for this job. To be more precise, gtkd is a wrapper for GTK. Gtkd is not interesting in this context, but the dependency on gtk. On windows you have the possibility to either publish your application with GTK dlls or to run gtk setup routine as part of your application setup routine or just say in your readme that the customer needs to run GTK setup on there own. On posix (linus, macos) of course you can also say in your readme that the customer should run apt-get ... to install gtk (here I do not have much knowledge on packaging). Kind regards Andre I will immediately abandon any app that provides this sort of incomplete experience to use unless I have my developer hats on...or I really have not other choice.

I haven't tried with D yet, but I use C# and mono calling into the pigpio C library (http://abyz.me.uk/rpi/pigpio/pdif2.html) and it workes great. You should be able to do the same with D. Mike I have no idea how to do that from D. Any help/resources on that?

It is a C library written by Bartosz Golaszewski. He is actively working on it. The latest update is a week old. It has the advantage that you don't have to use sudo to access the gpio pins. It comes with a set of tools written in C that I have been converting to D. Since my knowledge of both D and C is weak it has taken me some time to get things going. I have a hand written D bindings file that is incomplete and of amateur quality. So far I have converted 2 of the 6 command line tools that Bartosz Golaszewski provided to to work with the library. David Chapman your code... can you push it to GitHub so I can check it out?
