I know there is WS server as a part of vibe.d, but it does not seem to include client. Maybe there are some library bindings that I've missed? We just implemented one in D.

Ranges are fantastic, and the basic concept is solid, but a number of the implementation details really weren't worked out well enough in the beginning, which means that there's a lot of stuff that works reasonably well with ranges but falls apart on some level in certain circumstances - and what happens when ranges get copied is a big part of that. On some level, it's what we get for being the first language to really implement ranges as part of its standard library. As I understand it, Andrei didn't create the concept, but AFAIK, it wasn't implemented on any real scale by anyone prior to them being added to Phobos. And when you're the first to implement something, you often screw it up on some level. With many things, D was able to learn from C++ and improve, but this is an area where we got to make new mistakes. The result is something that's extremely useful and largely works but which has some problematic corner cases that really shouldn't be there. - Jonathan M Davis
Re: GTKD for android?

Since I have never been able to actually get anything to work on android I'm curious if there are any demos with gtkD for android? I'm wondering if I just scrap the idea of using it because it won't port without a ton of work. Ideally I'd like to just cross compile and it all work out except for a few bugs. The GtkD maintainer said a couple years ago he might try it when the Android support was better: https://forum.dlang.org/post/o4rq0i$dur$1...@digitalmars.com I don't think anyone's tested it yet, do you know if Gtk supports Android well? The DlangUI maintainer did get his GUI library working on Android, as James mentioned: https://forum.dlang.org/thread/cdekkumjynhqoxvmg...@forum.dlang.org
DlangUI and android
Is there an emulator that can run the apks? Android emulator does not work, I suppose, because it isn't java. Complains about a missing classes.dex file. I'd rather have an emulator version if possible for quicker dev.
dub doesn't work with dmd 1:2.082.0-1.0?
dub was working nice until I updated my system (I run ArchLinux32) just now. dmd was updated from version 1:2.081.2-1.0 to 1:2.082.0-1.0 (according to pacman package manager). After that, I couldn't invoke dub for anything. Here is the attempt to run `dub --vverbose`: ``` Using dub registry url 'https://code.dlang.org/' Refreshing local packages (refresh existing: true)...

Thos sounds memory violation somewhere. This only happens when using parallel. Any guess what's possibily happeing? If that only ever happens at line breaks, then that doesn't necessarily look like memory corruption to me. Yes, it does only happens at line breaks. I hadn't realized that until you mentioned. It does gets in place of \r and \n, that's why there's all in one line when this happens. Thankfor for the notice. I looked around a bit and found code page 437 [1]. It has those characters at 0xD and 0xA which is where ASCII has \r and \n. So it might be that code page 437 is used when displaying that particular entry. Why that would happen, I have no idea. So I guessed that something changed the console code page. I've tried to call call chcp 65001 at program's start up. Not worked. Tried inside the main loop. Also not worked. To get better help, you should post a complete test case that people can just copy/paste. That includes imports, a `main` function, and the command you use to compile. Also add information about your environment (OS, compiler version). I made a reduced version where you can do just dmd -run hello.d. The application does convert alot of PDF files to text then do some parsing (I've removed this not needed part). In my code, at iteration 28 I got those character (♪◙), which is the error. I hope you can reproduce this error on your machine as well. I got some PDF files and duplicated them just for testing purpose. If for some reason you didn't get the same error immediately, try duplicate the PDFs and try again. I believe this can reproduce the erro. Here's the resources to compile the application: source code: https://pastebin.com/RwrUikQS PDF files + pdf to text application: https://drive.google.com/file/d/1uKjJX4pQIEWVK4vujUsm0ln2yHS7z5ZZ/view?usp=sharing OS: Windows 10 64-bit compiler: DMD32 D Compiler v2.080.0 (same issue happens on ldc) command line: dmd -run hello.d Thank you very much for your time.
