You should only do this if there's no reasonable way to avoid it. Really?? IME, usually you *need* to do work in popFront instead of front, because otherwise .empty wouldn't be able to tell whether there is another element or not. E.g., in filtering a range based on some criterion on each element, you can't defer computing the next element until .front because you can't predict whether there will be another element that won't be dropped by popFront. Also, for ranges based on generator functions, if .front is lazy then you need to keep extra baggage around your range to indicate whether or not the generator has been invoked yet; it's easier to just always compute the next element eagerly and cache it, and .front just returns the cached data. Even when the range involves some expensive per-element computation, I find that it's simpler to just compute and cache in .popFront instead of adding extra baggage to .front to know when the computation has already been performed. I'm hard-pressed to come up with an example where deferring computation to .front is a good idea! T Well, I just remembered that I had a tab open to this: http://ddili.org/ders/d.en/ranges.html Reading, you see the following: * empty: specifies whether the range is empty; it must return true when the range is considered to be empty, and false otherwise * front: provides access to the element at the beginning of the range * popFront(): shortens the range from the beginning by removing the first element Looking at that, if popFront shortens the range, then to me it sounds like the work should be done in popFront.

On Thursday, 30 April 2020 at 16:21:05 UTC, Steven Schveighoffer wrote: I would say part of the issue is that you are doing all your work in front and not popFront. What happens is that Appender is a pointer-to-implementation struct, and the compiler will allocate the first one shared amongst all initial StreamRange instances. On your first call to front, it's going to utilize that shared one. Then on the call to popFront, it will reset it to another one. For the second unittest, in your first call to front, it notices that it's already been filled, so it doesn't do any work (and returns the existing buffer). Interesting. I'll take this into account. I was putting the work into front because I didn't want to do the work until it was requested. Putting the work in popFront makes more sense in some ways, but the fact you have to call it before getting any records seems like it would break normal range algorithms. (Please correct me if I'm wrong) I'm wondering if putting the work into it's own method and calling it one from the constructor and from popFront the rest of the way. another problem, your empty condition is based on the input, which violates range expectations. indeed, on the first call to front, the range all of a sudden becomes empty. I was about to argue the point, but after thinking about the use of popFront to execute the work, that would work. 3. You don't need a further Range parameter for the nested struct, it can use the template parameter from the containing function. 4. Make it a static struct, or else it will retain a pointer to the function stack frame needlessly. I'll definitely try that out. Regarding 3, I think that was in the example code I used, so I just went with it.

O.K. It's working now, but I suspect there may still be something else going on. The more I think of it, the more I suspect there's a newline at the end of the file that isn't accounted for until after the last tag is read from the file, so the input is not empty, so my code's empty check fails. Regardless, thanks for the help!

I was just trying to get the example to a very minimal state. I just added more descriptive code that replicates the bug. What's the value of count when the code asserts? The count ends up being the count of the previous test + the count of the current test. In the code I uploaded, the first test will get 1, but the second test will get 2. I'm printing out the output of the range to force it to actually perform the loop, so you can see that the contents of the first file are printed twice.
Re: Can't recreate a range?
Here's a minimal code example that duplicates the issue:
import std.array, std.range, std.stdio, std.traits, std.string;
auto readStream(Range)(auto ref Range r) if
(isInputRange!(Unqual!Range))
{
struct StreamRange(Range)
{
alias R = Unqual!Range;
R _input;
auto buff = appender!string;
this(R input)
{
this._input = input;
}
bool empty()
{
return this._input.empty;
}
string front()
{
if (buff.capacity == 0)
{
bool iterate = true;
bool doCapture = false;
buff.reserve(1000);
while (iterate)
{
if (this._input.empty)
break;
auto value = this._input.front;
if (value.strip == "")
{
doCapture = true;
buff.put(value.strip);
buff.put("\n");
}
else if (value.strip == "")
{
buff.put(value.strip);
doCapture = false;
iterate = false;
}
else if (doCapture)
{
buff.put(value.strip);
buff.put("\n");
}
this._input.popFront();
}
}
return buff[];
}
void popFront()
{
buff = appender!string;
}
}
return StreamRange!(Range)(r);
}
unittest
{
auto range = readStream(File("test1.xml").byLine);
int count = 0;
while (!range.empty)
{
writeln(range.front);
count++;
writeln("Current count: ", count);
range.popFront();
}
assert(count == 1);
}
unittest
{
auto range = readStream(File("test2.xml").byLine);
int count = 0;
while (!range.empty)
{
writeln(range.front);
count++;
writeln("Current count: ", count);
range.popFront();
}
assert(count == 1);
}
Here are the two XML files (very simple):
Here is some text for the first file.
Here is some text for the second file.
I've even tried putting wrapping the code that is being tested in
a function and looping over it with different parameters
(filename and expected count) without any luck either. I've also
tried declaring the file handle separate and ensuring it was
closed. No luck.
Can't recreate a range?
So, I'm trying to run some tests and I had code that looks
similar to this:
unittest
{
auto range =
readStream(File("test_data/multiple.xml").byLine);
int count = 0;
while (!range.empty)
{
count++;
range.popFront();
}
assert(count == 3);
}
However, if I have a second block above/below it doing the same
thing, the last assert will fail because in the second block it
appears the ranges have been joined together. E.g.:
unittest
{
auto range =
readStream(File("test_data/multiple.xml").byLine);
int count = 0;
while (!range.empty)
{
count++;
range.popFront();
}
assert(count == 3); // Passes
}
unittest
{
auto range =
readStream(File("test_data/another.xml").byLine);
int count = 0;
while (!range.empty)
{
count++;
range.popFront();
}
assert(count == 2); // Fails
}
To me, it looks like range is not being overwritten. The code
for readStream looks similar to this:
auto readStream(Range)(auto ref Range r) if
(isInputRange!(Unqual!Range))
{
struct StreamRange(Range)
{
alias R = Unqual!Range;
R _input;
this(R input)
{
this._input = input;
}
bool empty()
{
return this._input.empty;
}
string front()
{
// Do stuff...
}
void popFront()
{
}
}
return StreamRange!(Range)(r);
}
I feel like I'm missing something obscure and it's driving me a
bit batty. Any clue as to why this is happening? I'd like to
not have to worry about creating new variable names between
tests. To me, it seems like each unittest block is independent
of each other and I haven't come across anything that contradicts
that. However, I didn't find anything that confirms it either.
Thanks.

Dub and unit-threaded import problem
Hello,
I'm just starting a small project with dub and unit-threaded, but
I'm getting an issue where the file "unit_threaded.d" cannot be
found.
Details:
DMD version: DMD64 2.070.0
Dub version: 0.9.24
Dub Config:
{
"name": "pst",
"targetType": "executable",
"targetPath": "bin",
"configurations": [
{
"name": "unittest",
"preBuildCommands": [
"dub run unit-threaded -c gen_ut_main -- -f
bin/ut.d"
],
"mainSourceFile": "bin/ut.d",
"excludedSourceFiles": ["source/app.d"],
"dependences": {
"unit-threaded": "~>0.6.3"
}
}
]
}
I haven't created any tests at this time. It's a bare project.
I just wanted to make sure the dub config worked before I started
coding. I feel I'm missing something very simple. I just don't
see it.

Re: Basically want to make a macro script
Well, I edited the code to add the chat button, and as I feared it didn't recignise it in game. However, if I manually press the chat button it'll work fine, so all I need to do is add that delay in, then fine tune it to add all of the different messages I need now. 1)What part of this do I need to keep when adding the second hotkey? Include an example if possible. I find it hard to understand what is necessary to repeat and what I can just include once. 2)All I need to do at the moment to enable this to work is to add a ~1ms delay from the time the chat key is pressed down, and when it is pressed up. Then it /should/ funtion in game properly. 3)It's a personal preference of mine to not have the chat window pop up like it does, nor the terminal popup. This is a minor request, so I don't need it immediately. Is there any way to make those disappear? 4)I'd like the first hotkey to be 0 + 1 on the numpad. Numlock is always enabled on my keyboard, so I can't use arrows or anything like that. The second set of hotkeys would be Ctrl + Del/End/PgDn/Insert/Home/PgUp, each one sending a different message. 5)Is there any way to pause the commands? I have one hotkey set to Ctrl + Delete, and it gets really annoying when I try to Delete a full word but instead I send a chat message. I think that I could activate and pause it with another hotkey, something like ctrl + numpad 0. That should be something I'd never press. I'm going to see if I can't figure everything above out on my own. Maybe I'll start to learn it a bit more. I'm also assuming I'll need another package to be imported if I am to add that delay, but it might already be in one of these. Thanks so much everyone for your help. It really means a lot to me.
Re: Basically want to make a macro script
Aha! I found a sleep command. On this page here: http://forum.dlang.org/thread/diuepu$2ebg$1...@digitaldaemon.com Looks like I'd do something like this [code] import std.c.time msleep(1) [/code] Now I'm looking into if there's a way to send a key down, and then up. I don't think this will be too easy to find though.

I find it hard to understand what is necessary to repeat and what I can just include once. The RegisterHotKey function will need to be called again with a new ID. Then, the WM_HOTKEY message will have to handle the other hotkey id too. You can copy and paste every instance of hotkey_id to make a hotkey2_id in a pinch. I know there's a lot of concepts behind the MSDN pages that aren't all newbie friendly (well, actually, there are pages on it to explain the concepts too, in the References part at the bottom of each page. You'll be in for many hours of reading though, it took me weeks to get going beyond copy/paste and it was /years/ before I knew all the concepts, but gotta start somewhere). Anyway, take a look at the pages to better understand what the code is doing - the concepts will make sense too once you see enough of it and in the mean time, it can help to explain the pieces in isolation. http://msdn.microsoft.com/en-us/library/windows/desktop/ms646309%28v=vs.85%29.aspx http://msdn.microsoft.com/en-us/library/windows/desktop/ms646279%28v=vs.85%29.aspx http://msdn.microsoft.com/en-us/library/ms646310%28v=vs.85%29.aspx http://msdn.microsoft.com/en-us/library/ms646271%28v=vs.85%29.aspx This is all Windows specific, of course, but the concepts apply to a lot of systems - if you can write Win32 code, you can do a lot of stuff. 2)All I need to do at the moment to enable this to work is to add a ~1ms delay from the time the chat key is pressed down, and when it is pressed up. Then it /should/ funtion in game properly. The easiest way would be to split up the part that does SendInput into two parts - notice how in the code, there were separate events for pressed and released. You'd need to split that up into two separate calls to SendInput with some kind of sleep in between. There's also a timestamp thing mentioned in the MSDN docs which might work but I'm not sure that would actually work. 3)It's a personal preference of mine to not have the chat window pop up like it does, nor the terminal popup. This is a minor request, so I don't need it immediately. Is there any way to make those disappear? The terminal won't appear if you use the -L SUBSYSTEM thing from a previous post on the compile command at the end of the lit of files. The window itself could be hidden with the ShowWindow system function, but then you'd have to consider: how will you close the program when you don't want the hotkeys registered anymore? Having a visible window makes that easy. http://msdn.microsoft.com/en-us/library/windows/desktop/ms633548%28v=vs.85%29.aspx The hwnd ShowWindow needs is available through window.impl.hwnd, so like ShowWindow(window.impl.hwnd, SW_HIDE); i should add this to simpledisplay.d too... 4)I'd like the first hotkey to be 0 + 1 on the numpad. Numlock is always enabled on my keyboard, so I can't use arrows or anything like that. The second set of hotkeys would be Ctrl + Del/End/PgDn/Insert/Home/PgUp, each one sending a different message. The Virtual Keys thing is the answer here. Search for virtual key codes on MSDN and you'll find this http://msdn.microsoft.com/en-us/library/windows/desktop/dd375731%28v=vs.85%29.aspx Then search that page for Numeric keypad 0 key and you'll find the VK_NUMPAD0 name and number. 5)Is there any way to pause the commands? I have one hotkey set to Ctrl + Delete, and it gets really annoying when I try to Delete a full word but instead I send a chat message. I think that I could activate and pause it with another hotkey, something like ctrl + numpad 0. That should be something I'd never press. This is pretty straightforward: you can use an if clause with a variable in the WM_HOTKEY message to skip processing. Or, you could use UnregisterHotKey, passing the hwnd from the window and the ID number to turn it off entirely, then RegisterHotKey again later to turn it back on. I'm going to see if I can't figure everything above out on my own. Maybe I'll start to learn it a bit more. I'm also assuming I'll need another package to be imported if I am to add that delay, but it might already be in one of these. core.thread is one you can import, that gives you Thread.sleep http://dlang.org/phobos/core_thread.html#sleep This isn't the way you'd do this in a real program - it is usually a bad idea to sleep the thread responsible for handling window messages because then it can become unresponsive, but as long as you only sleep for a few milliseconds at a time it shouldn't

I don't need to rootkit PunkBuster, it's not trying to ban programs that send chat messages It's simply trying to ban macro programs like AutoHotKey. AHK can be used to make no recoil scripts, so they added an option so that server owners can choose to kick those players /if they want to/. Again, I'm writing a simple program to send chat messages at a lowish level once a hotkey/keybind has been pressed. All it needs is to add a delay in between the chat key presses (Like *chat key* down, then 1 ms later, chat key up)(Forgot to mention that last night), typing my actual message as quickly as possible, then to send the message. In other words, it needs to recignise my keybind, press the chat button down, then up with a small delay in between, send my message and press enter. PB nor any other program should find this as a cheating program. It's not a cheat at all. It's not a mod, hack, nor advantage that others can't do. It's not unfair, it's not too good, it's just something simple that I'm trying to make work. It doesn't need a GUI, it just needs what I've described above. No rootkits, nothing like that afaik. If it's not a hack/cheat, PB isn't going to look at it like it is one (hopefully). Thank you for your interest and reply.

There are few libraries that allow you to take control over the mouse and keyboard without too much hassle and reading through documentation.

So of course, it won't work for what you want, it just creates a window and a context cross platform with input for that window. The functionality you are wanting is possible against winapi and x11 fairly easily. Its just low level. Although X11 is a little easier as it can be done via a program on cli. Unfortunately c/c++ will help you as much as D will in these cases. If you run into trouble with those api's we can help you. But you will need help, these are topics that aren't recommended for a newbie. I'm not quite sure how to receive key presses from other windows. Maybe Mike Parker (aldracon) has some ideas. Do you have plans for making win32 bindings for the sendkeys? Im interested in this too. Id like to do it with D but ive only ever been able to accomplish this task with C# and InputSimulator. At this point in time, I have no plans for such a library. However if somebody wishes to implement under the devisualization org, I'm happy to help. It's great to have you two joining in on this thread! I'm excited to see how helpful you have all been, it's really encouraging me to learn more about this. Two of you guys have noted that D and C++ might not be the right languages for my purposes. If they won't work for it, could you make some other suggestions? I'd really prefer to make it work in D, but if it's not worth the trouble I'm more than happy to switch to something simpler. Thanks for your dedication all!
Basically want to make a macro script
/Long/ story short, I want to pretty much make a macro using this
program. I don't really have time to explain in further detail
at the moment, but /no/ macro program out there will do what I'm
trying to do. I want to basically make it so that when I press a
hotkey, it'll send an in game chat message. Here's my code for
the popular program AutoHotKey.
[code]
Numpad0 Numpad1::
Send {k down}
Sleep 1
Send {k up}
SendInput We're losing Alpha{!}
SendInput {Enter}
Return
[/code]
That's a small sample of my script, but the only thing that would
change with the rest of my script would be the message sent and
the keybind to press it.
Basically what it's doing is listening for my hotkey to be
pressed (in this particular example it's numpad 0 + numpad 1 for
the message, We're losing Alpha!, and so on and so forth for
the rest of the numbers.) and then activating the chat button in
game (in this particular examle it's k for team chat), then
sending the actual message as quickly as possible, and sending
it. Works perfectly in BF4, but PB (PunkBuster), the default
anti cheat system that BF4 uses will kick me if the admins have
that setting enabled.
I've been wanting to learn full on programming for a while, and
I've heard a lot of things about D and how it's a pretty good
starting point, and how it has a huge potential to expand you
into anything. Plus it's supposed to be pretty efficient and the
next big thing in the programming world, so there's that.
Just for the record, I don't have a lot of experience with
programming. I've done it years ago (had an instructor for a Boy
Scout Merit Badge class), but I didn't even know which language I
was typing in. I assume it was Python, but I can't be sure.
Whatever I make I want it to be somewhat compatible with Linux
eventually. I just want to start with a binary .exe, but I do
want my code to be compatible with Linux if I choose to compile
it for Linux at a later date. I don't think this should be an
issue, but I just wanted to throw this out there.
I'm not sure which libraries I need for this, but as far as I
know I just need the following:
Keybind listener/hotkey
Keyboard emulating/low level chat producing library
something that /wont/ be picked up as a hack/cheat by /ANYTHING/.
I don't think this should be that hard to make, but D doesn't
really have much documentation out there as far as I can tell, so
I figured this would be the best place to put this.
The sooner the better please. Thanks for any/all help I receive.
Variable Naming Issue (Conflicts?)
Hello,
I'm working on some code where I'm trying to generate structs
that map to JSON documents via a mixin. That part works except
when specific variable gets created. Below is the error that I'm
getting:
source/objects.d-mixin-70(75): Error: no identifier for
declarator string
source/objects.d-mixin-70(75): Error: found '=' when
expecting '('
source/objects.d-mixin-70(75): Error: basic type expected,
not
source/objects.d-mixin-70(75): Error: found '' when
expecting ')'
If I prefix all of the generated variables with an underscore, it
works fine. It looks like the variable delete is the issue.
To me, it looks like it's expecting some sort of delete method.
Now, I'm planning on leveraging vibe.d's JSON serialization to
convert an object to/from JSON, so the variable names have to
match the names they have in the JSON document.
My question is, is there a way I can prevent this conflict from
occurring without affecting what the struct will look like?

The usual strategy is to append an underscore. (I think C# uses a @ prefix). Bye, bearophile I've done that, but then it changes the name which, from what I've read in the documentation, means the JSON - object conversion won't work since it won't see a variable named delete.
Re: Variable Naming Issue (Conflicts?)
Perhaps we need a built-in syntax solution as in C#, like a $delete. So, two things: 1. I guess my current approach is screwed. I figured as much. 2. Seeing $delete makes me miss Perl/PHP variable naming. It is one extra character, but it did make them stand out more. Anyway, thanks. Casey
