Delphi and "Use only memory safe languages"
David Heffernan replied to Die Holländer's topic in General Help
I don't really understand this. I always write the try/finally immediately after the construction, and always bang the Free in immediately. Then I fill out the body. It's just a habit that you form so that you don't make such mistakes. And honestly, this is never one that is hard to debug because you just have a leak. And presumably you use leak detection tools so that you'd always find them immediately. I don't really understand this scenario either. If you have a reference to something that may or may not exist, you would test Assigned() before using it. And when you were finished, you'd set the reference back to nil once you'd destroyed it. The scenario that is tricky is when you have multiple references to an object. -
Do you need an ARM64 compiler for Windows?
David Heffernan replied to Lars Fosdal's topic in Cross-platform
I think all in all, it's clear that the current in-process design is the right one -
Delphi and "Use only memory safe languages"
PeterBelow replied to Die Holländer's topic in General Help
Consequent use of interface references (with rerf counting for lifetime control) instead of object references avoids that problem completely. -
Delphi and "Use only memory safe languages"
Dalija Prasnikar replied to Die Holländer's topic in General Help
If you really need to have multiple references to an object, then use interfaces and ARC to manage lifetime. If not, then you will have to invent similar mechanism for managing the lifetime. -
Delphi and "Use only memory safe languages"
David Heffernan replied to Die Holländer's topic in General Help
It's odd you say that, but I never have to debug issues like this. There are two simple patterns for lifetime and they are so ingrained, nobody ever makes a mistake in my team. -
That's not how you do it. I doubt Remy will have time or motivation to look at whatever it is you have done. Fork the original repository. Make a branch. Apply your changes. Create a pull request to have your changes merged into the original repository. 2-4 should be done once per separate issue. A single issue that makes 20 unrelated changes probably has zero chance of being accepted.

Hi fellows, I wanted to inform you that I have made an improvement to my AI-integration plug-in called ChatGPTWizard. Now it supports Ollama, the offline AI chatbot server. You can download the latest version (v3.0) to try it out here: https://github.com/AliDehbansiahkarbon/ChatGPTWizard To set up your offline GPT-like server read this section: https://github.com/AliDehbansiahkarbon/ChatGPTWizard#:~:text=How to use it in Offline mode I am eagerly looking forward to receiving your valuable feedback. Thank you in advance.

Delphi and "Use only memory safe languages"
Anders Melander replied to Die Holländer's topic in General Help
Do you really want your code to be generated based on fuzzy statistics? How do you even verify the correctness of the results? I'd like mine to be based on strict patterns and known deterministic properties of those patterns. I think trying to solve these problems with AI is a bit like when some companies moves their stuff to the cloud; They don't understand how it works or know what is going on but now it's somebody else's problem. -
Strange bug with string literals in RAD Studio 12
Uwe Raabe replied to luebbe's topic in RTL and Delphi Object Pascal
Could be related to String with non-ASCII characters directly attached to a #xx or #$xx literal corrupts the final string Current workaround is to use a + operator to concatenate the parts. -
Again? What was old is new again - except my jokes.

Writing if statement in the Code Editor
Brian Evans replied to PeterPanettone's topic in Delphi IDE and APIs
Reproduced in Delphi 12.1 here - turned on hints and see the same thing. The hint window has broken positioning - the bottom of the hint window is where the top should be. Usually run with scale 125%, switched to 100% and the improper positioning is still there and looks the same. In addition the hint window should be moved further away or the drop shadow removed as it will obscure text. -
Is this an April 1 joke?

Yes, I fear it will. While I haven't used it yet and there's presently nothing there, I'm really afraid this just wiped out yet another small community. Tick tock, tick tock.

One option would be to add some operator overloading to TProductID: type TProductID = record ID: nativeint; public class operator Explicit(A: TProductID): NativeInt; overload; class operator Implicit(A: NativeInt): TProductID; overload; class operator Implicit(A: TProductID): string; overload; end; class operator TProductID.Explicit(A: TProductID): NativeInt; begin Result := A.ID; end; class operator TProductID.Implicit(A: NativeInt): TProductID; begin Result.ID := A; end; class operator TProductID.Implicit(A: TProductID): string; begin Result := A.ID.ToString; end; This allows to write something like this: var cid : TCustomerID; var pid: TProductID; pid := qryGetStockProductID.AsInteger; cid := qryGetStocCustID.AsInteger; --- procedure TForm6.AddToStock(pid: TProductID; cnt: nativeint); // Both uses internally nativeint begin ShowMessage(pid); end; Note that the operator to convert TProductID to NativeInt is Explicit instead of Implicit. That prohibits the use of TProductID as a NativeInt parameter and the compiler throws an error when the parameters to AddToStock are given in the wrong order.

Same thing happened to me re Ios Island 🙂 Following the live activities link leads to: https://developer.apple.com/documentation/ActivityKit/displaying-live-data-with-live-activities Which talks about using Widget Extensions, which are yet to be possible in Delphi, however there's a slim chance that the extension can "talk" to Delphi code: https://blog.grijjy.com/2018/11/15/ios-and-macos-app-extensions-with-delphi/ I have very little optimism about the possibility

I mean, how hard could it be???? -
Delphi and "Use only memory safe languages"
Lars Fosdal replied to Die Holländer's topic in General Help
That is not what I intended to say. I was wondering if someone had tried to apply LLM for finding even better patterns for optimization than those that are currently implemented. Naturally, such improved patterns would be made into new deterministic rules in the compiler after being properly vetted. I agree that todays AI output has to be treated as indicative at best, and as bullshit at worst. -
Writing if statement in the Code Editor
PeterPanettone replied to PeterPanettone's topic in Delphi IDE and APIs
That's what I am going to do. Before doing that, I always ask other people whether they can confirm the issue. So much wasted time because the Embarcadero developers obviously didn't care. -
Delphi should let me use a const array reference as a constant
Stefan Glienke replied to PiedSoftware's topic in RTL and Delphi Object Pascal
Imagine you could write this code in Delphi: var i: Integer = 42; begin const j = i; Writeln(j); end. Oh, wait, you can. Too bad that the syntax is not really clean as it mimics the const declaration using the equal sign while it really is what other languages call immutable variable and thus should have used the assign operator but people with even less expertise in programming language design than me disagreed. -
I guess they will be able to say that the numbers of bugs reported is going down and claim that indicates quality has improved.
-
Yes, you can safely ignore them ( until Google decides to enforce this probably in the future ). I considered that too, but I'm afraid these warning will be hard to remove, because they require certain Android tools, like ProGuard. Not sure if this will be ever included in the Delphi process. One idea, at least for the first warning, was to add a neutral or empty "manifest.txt" file. This might work technically, but on the other hand, the Google Review might see this as an attempt to circumvent or infringe their PlayStore policies, which might put you in bigger troubles. My hope is, that Embarcadero put this onto their roadmap.

Do you need an ARM64 compiler for Windows?
Brandon Staggs replied to Lars Fosdal's topic in Cross-platform
Embarcadero's ARM compilers use an LLVM backend. This leads to differences such as how exceptions are handled. This is not a trivial difference and this is likely only scratching the surface of the problems that would have to be resolved. They haven't even given us a 64-bit Intel IDE yet. I doubt ARM64 is anywhere near. This is also likely one reason native Windows ARM compile target is not going to be available soon or if it is, will not be a simple matter of recompiling for many non-trivial projects. -
Looking for a couple of good "starter" Delphi books
Nigel Thomas replied to t2000kw's topic in General Help
Don't get hooked up on just books. There is a lot of useful visual material on the Net that is targeted at Delphi beginners. Embarcadero's Helpful Resources for New Users has some good links to both books and visual resources.
