But we have Vibe Coding now!

As @DelphiUdIT already said: The first thing you need is a compiler that creates binaries for Linux. And Delphi Professional - regardless which version - doesn't include that. According to Embarcadero's overview, you need at least the Enterprise SKU. On top of that, you might need GUI libraries, this is where FMXLinux comes into play. Of course the question is, whether you actually need a GUI. What kind of applications do you plan to develop?

Just to make one thing clear: GExperts does not support the 64 bit version of the IDE and the installer does not add it to that IDE. The error you get regarding the UsesClauseManager may well be caused by a problem of the IDE itself before that. I don't use the C++ personality of Rad Studio (I usually only install the Delphi personality), so I can't really say anything about the cause. And since nobody else working on GExperts (there currently is 3 of us off and on) uses C++, there is little chance of fixing any problems with it. Unless of course somebody else steps forward now.

I just built a test installer for 12.3. Note: This is from the current source code, including all the bugs I might not yet have found. http://download.dummzeuch.de/GExperts/1.3.25_2024-08-24/GExperts_RS12_test-for-12.3_2025-04-13.exe Note to people who might read this later on: I might delete that file without notice at any time in the future. There will hopefully be a new release by then.

I am using GExperts with Delphi (RAD Studio) 12.3 and it works just fine. But admittedly I am using a DLL compiled from the current sources. What do you mean by "the IDE fails to start"? Is there any error message?

It apparently is: It does not happen on my laptop with a single HD screen. Nor on my desktop when I turn off the 4K monitor or alternatively the HD monitor. And after starting Delphi once with only the HD monitor connected, it no longer happens with both monitors. Sounds like an easily reproducible problem, doesn't it?

I just realized that this might be a bug: All my IDE windows look like this. The close button is not displayed, but it is there and works. Is that just another oddity of my particular installation(s) or does this happen everywhere? When the window is drawn I can for a short time see that there is actually a red button with a diagonal cross in it, like it should be, but it is overwritten with just the blue title bar. This is also the case for the main IDE window itself. Docked windows do have the close button, but as soon as I undock them it disappears too. It comes back when I dock them.

You probably copied source code that only contained line feeds (#10) or only carriage return (#13) rather than the Windows (DOS) convention with carriage return followed by line feed (#13#10). Notepad cannot handle this, other editors (e.g. Notepad++) can. The latter can also convert between the different styles too. The IDE in the latest versions can automatically correct that for you, if this option is enabled.

IDE toolbars get scrambled over time The toolbars of the IDE lose icons when starting, exiting and restarting the IDE multiple times (see screenshot). This bug had already been reported in the old quality portal for Delphi 11 and 12. It’s still there in Delphi 12.1. Resetting the toolbars to their default using the View → Toolbars → Customize dialog, helps for a while before the same happens again. https://embt.atlassian.net/servicedesk/customer/portal/1/RSS-515 It seems to have been fixed in Delphi 12.3, at last I have not seen this problem after I updated my installations. Maybe it has been fixed? The bug report is still open though, so maybe that was a side effect of some other change?

Yes, but the problem I reported still happened in 12.2. That's why I created a workaround when I started using Delphi 12(.2) in earnest.

I am sure it has been like this from the first Delphi 12 installation which of course was "vanilla" back then. But since I just realized it might be a bug I have not yet tried to reproduce it. Knowing my luck, it might be yet another effect of using two screens in a peculiar setup that's apparently unique on planet earth.

I am using ISshExec.Exec from @pyscripter's ssh-pascal library for running a command that calculates checksums on all files in a directory tree. Since this is potentially a large tree and some of the files are huge, this takes quite a while. Unfortunately Exec is synchronously waiting for the output of the command which creates two issues: My program has to wait for the command to finish before it can get any output. For the huge files calculating the checksum takes longer than the standard timeout which raises an exception in the Exec method (actually in ReadStringFromChannel) and stops reading (the command continues running though) Is there any existing way to get the output asynchronously? EDIT: I just found that my ssh-pascal library was outdated, in particular the reading code has changed significantly. Maybe my second point has become moot. I'll check. EDIT2: No, the timeout still occurs. EDIT3: Hm, now I can't reproduce the timeout. Maybe I didn't rebuild the executable correctly before trying, so it was still using the old code.

Here you go: type TOnSshExecDataRecieve = procedure(const AData: TBytes; ADataLen: Int64) of object; // ... { Execute commands on the host and get Output/Errorcode back } ISshExec = interface ['{CA97A730-667A-4800-AF5D-77D5A4DDB192}'] procedure SetBufferSize(Size: Int64); procedure Cancel; // ---- change procedure SetOnStdErrReceive(ACallback: TOnSshExecDataRecieve); procedure SetOnStdOutReceive(ACallback: TOnSshExecDataRecieve); // ---- endchange procedure Exec(const Command: string; var Output, ErrOutput: string; var ExitCode: Integer); property BufferSize: Int64 write SetBufferSize; end; // ... type TSshExec = class(TInterfacedObject, ISshExec) private FSession : ISshSession; FBufferSize: Int64; FCancelled: Boolean; // ---- change FOnStdErrReceive: TOnSshExecDataRecieve; FOnStdOutReceive: TOnSshExecDataRecieve; procedure doOnStdErrReceive(const AData: TBytes; ADataLen: Int64); procedure doOnStdOutReceive(const AData: TBytes; ADataLen: Int64); // ---- end change procedure SetBufferSize(Size: Int64); procedure Cancel; procedure Exec(const Command: string; var Output, ErrOutput: string; var ExitCode: Integer); // ---- change procedure SetOnStdErrReceive(ACallback: TOnSshExecDataRecieve); procedure SetOnStdOutReceive(ACallback: TOnSshExecDataRecieve); // ---- end change public constructor Create(Session: ISshSession); end; // ... // ---- change procedure TSshExec.doOnStdErrReceive(const AData: TBytes; ADataLen: Int64); begin if Assigned(FOnStdErrReceive) then FOnStdErrReceive(AData, ADataLen); end; procedure TSshExec.doOnStdOutReceive(const AData: TBytes; ADataLen: Int64); begin if Assigned(FOnStdOutReceive) then FOnStdOutReceive(AData, ADataLen); end; // ---- end change procedure TSshExec.Exec(const Command: string; var Output, ErrOutput: string; var ExitCode: Integer); var Channel: PLIBSSH2_CHANNEL; M: TMarshaller; ReadBuffer, OutBuffer, ErrBuffer: TBytes; StdStream, ErrStream: TBytesStream; TimeVal: TTimeVal; ReadFds: TFdSet; BytesRead: ssize_t; ReturnCode: integer; OldBlocking: Boolean; begin if FSession.SessionState <> session_Authorized then raise ESshError.CreateRes(@Err_SessionAuth); FCancelled := False; Channel := libssh2_channel_open_session(FSession.Addr); if Channel = nil then CheckLibSsh2Result(libssh2_session_last_errno(FSession.Addr), FSession, 'libssh2_channel_open_session'); TimeVal.tv_sec := 1; // check for cancel every one second TimeVal.tv_usec := 0; StdStream := TBytesStream.Create(OutBuffer); ErrStream := TBytesStream.Create(ErrBuffer); SetLength(ReadBuffer, FBufferSize); OldBlocking := FSession.Blocking; FSession.Blocking := False; try Repeat ReturnCode := libssh2_channel_exec(Channel, M.AsAnsi(Command, FSession.CodePage).ToPointer); CheckLibSsh2Result(ReturnCode, FSession, 'libssh2_channel_exec'); Until ReturnCode <> LIBSSH2_ERROR_EAGAIN; // Stop waiting if cancelled of Channel is sent EOF while not FCancelled do begin // Wait until there is something to read on the Channel Repeat FD_ZERO(ReadFds); _FD_SET(FSession.Socket, ReadFds); ReturnCode := select(0, @ReadFds, nil, nil, @TimeVal); if ReturnCode < 0 then CheckSocketResult(WSAGetLastError, 'select'); if libssh2_channel_eof(Channel) = 1 then Break; Until (ReturnCode > 0) or FCancelled; try // Standard output BytesRead := libssh2_channel_read(Channel, PAnsiChar(ReadBuffer), FBufferSize); CheckLibSsh2Result(BytesRead, FSession, 'libssh2_channel_read_ex'); // ---- change if BytesRead > 0 then begin StdStream.WriteBuffer(ReadBuffer, BytesRead); DoOnStdOutReceive(ReadBuffer, BytesRead); end; // ---- end change // Error output BytesRead := libssh2_channel_read_stderr(Channel, PAnsiChar(ReadBuffer), FBufferSize); CheckLibSsh2Result(BytesRead, FSession, 'libssh2_channel_read_ex'); // ---- change if BytesRead > 0 then begin ErrStream.WriteBuffer(ReadBuffer, BytesRead); DoOnStdErrReceive(ReadBuffer, BytesRead); end; // ---- end change except on E: Exception do begin OutputDebugString(PChar(E.Message)); Break; end; end; // BytesRead will be either > 0 or LIBSSH2_ERROR_EAGAIN until // the command is processed if BytesRead = 0 then Break; end; Output := AnsiToUnicode(PAnsiChar(StdStream.Memory), StdStream.Size, FSession.CodePage); ErrOutput := AnsiToUnicode(PAnsiChar(ErrStream.Memory), ErrStream.Size, FSession.CodePage); // libssh2_channel_close sends SSH_MSG_CLOSE to the host libssh2_channel_close(Channel); if FCancelled then ExitCode := 130 // ^C on Linux else Exitcode := libssh2_channel_get_exit_status(Channel); finally StdStream.Free; ErrStream.Free; libssh2_channel_free(Channel); FSession.Blocking := OldBlocking; end; end; // ---- change procedure TSshExec.SetOnStdErrReceive(ACallback: TOnSshExecDataRecieve); begin FOnStdErrReceive := ACallback end; procedure TSshExec.SetOnStdOutReceive(ACallback: TOnSshExecDataRecieve); begin FOnStdOutReceive := ACallback; end; // ---- end change This passes the raw bytes received to the callback. Maybe it is possible to convert them to a string first? Or maybe call every time a line feed is received? Also, maybe the callbacks are enough so collecting the whole output is no longer necessary. I'll see how far I get with this.

I'll probably implement something like this (if I get the time to finish this project). I'll of course submit a patch in that case.

My problem is not that the main thread is blocked by the call but that I get the output of the command only after it has finished (which can take 30 minutes). During that time the output is received and stored in a memory stream to be converted to a string. Access to this partial output not available. I know that I could adapt the source code to change that behavior. But I was asking whether I may just be missing something (maybe a different interface?) in the library that already exists. @pyscripter Yes, I am (now) using the latest sources. No I haven't updated the binaries, but the problem is in the Delphi code. (Just in case you missed my edits in the original question: The timeout no longer occurs.)

I for one loved Kylix, I even bought it twice - once through my employer (I partly owned the company at the time) and another one for personal use. That was a brief period when I hoped that Linux would actually take off on the desktop. Unfortunately, that never happened. Even now, with the end of support for Windows 10 looming and millions of perfectly usable computers in danger of being turned into electronic waste, Linux on the desktop is not gaining any visible market share.

Anybody remember OS/2? They had great support for running DOS and Windows 16 bit programs. So nobody bothered to write any native OS/2 programs. Guess what happened when Windows went 32 bits? (OK, that was not the only reason for OS/2's demise, but a big part of it.)

As always: Into the pockets of the parent company Idera. It's called a "Gewinnabführungsvertrag" in Germany. On the other hand how do you know that there are millions of Delphi users? And more importantly: Do you know that they have paid for a license recently? Maybe 99% of these supposed millions are still using Delphi 5 or 7?

Hm, on the Delphi history page it says: "Highest Position (since 2001): #6 in Oct 2001" But in the chart the maximum seems to be August 2004 with 5.87%: OK, one is the rank (#6 at 2.77%) the other is the percentage (5.87%), but it still seems odd.

I have multiple desktops created for my Windows 10 installation to easily switch between different tasks. When have the IDE open on one of these desktops, switch to a different one and then hibernate the PC, and later turn it on again, the IDE window shows up on the currently active desktop rather than the one where it was supposed to be. Create an additional Desktop on Windows (e.g. using the “Tasks” button on the taskbar). Start the Delphi IDE Switch to a different Desktop (e.g. using Win + Ctrl + Right) Now the IDE is no longer visible Hibernate the computer Turn on the computer again The IDE is now visible on the current Desktop, not on the one where it was supposed to be Has anybody else seen this happen? If yes, please comment on the bug report. https://embt.atlassian.net/servicedesk/customer/portal/1/RSS-3281

Nowhere, as you noticed correctly. I should not try to answer any forum posts when reading on my mobile phone. I simply missed that part of the setter method. (And on the phone apparently syntax highlighting is also not possible 😞 ) One could argue though, that, if the name should not be empty, it should be initialized in the constructor and possibly not even have a setter at all. But if the property should be writable, it could be done in a setter method but still without requiring a getter method: type TEmployee = class private FName: string; public property Name: string read FName write SetName; end; procedure TEmployee.SetName(const Value: string); begin if value='' then raise Exception.Create('Name must have a value'); FName := value; end;

If it's only about reading and writing values to the fields, there are two options: 1. Make the fields themselves public (and omit the 'F' prefix). If you later decide some of these fields should be properties, you can simply change the class without having to change the code that's using it. type TEmployee = class public Name: string; end; 2. Instead of having read and write accessor methods, declare the properties to directly access the fields: type TEmployee = class private FName: string; public property Name: string read FName write FName; end;

The venerable Delphi IDE extension GExperts is about to undergo a revolutionary transformation, with plans announced to completely rewrite it using artificial intelligence and simultaneously port it to COBOL. This unexpected development marks a significant shift for a tool that has been a staple in the Delphi programming community for decades. The AI Rewrite: Starting Now The development team has just announced their decision to leverage artificial intelligence for the rewrite after facing increasing challenges maintaining the extensive codebase. What’s remarkable is the anticipated timeline – the team expects the entire process to take only a few hours once it begins. This unprecedented speed is attributed to advancements in AI code transformation technology. The AI system will analyze the entire GExperts source code, understanding its purpose, functionality, and even the quirks that make it uniquely useful to Delphi developers – all in a fraction of the time it would take human developers. Why COBOL? Perhaps the most surprising aspect of this transformation is the announced port to COBOL. This decision has raised eyebrows among the development community, as Delphi and COBOL represent dramatically different programming paradigms and eras. However, the team cites strategic reasoning behind this choice. COBOL continues to power critical systems in banking, insurance, and government sectors worldwide. This port will open GExperts to an entirely new ecosystem, potentially breathing new life into the project while serving developers maintaining legacy systems. Expected Timeline The project has not yet begun, but development is scheduled to start immediately. With the AI-powered transformation expected to take only a few hours from start to finish, the team anticipates having a functional COBOL version of GExperts available for testing within days rather than the months or years such a port would traditionally require. Looking Forward For developers interested in this innovative crossover, beta releases are expected to be available remarkably soon, with the team promising updates on the progress within the next 24 hours. This bold reinvention of GExperts, once completed, will demonstrate how established developer tools can evolve in unexpected ways, leveraging new technologies to reach broader audiences while maintaining their core value proposition. (Yes, AI is great! Even for writing April Fools jokes. Thanks to Claude.ai writing this only took a few minutes and it actually sounds like a press release some cool cloud AI blockchain outfit could have written.) Original blog post here.

So you are saying that Elon Musk and those highly intelligent and capable people who work for him at DOGE don't know what they are talking about when they say they can convert the large COBOL code base to Java in months using AI? Or does that only apply if COBOL is the target language?

Thank you, but I am confident in using AI for the conversion. I'll call Elon Musk at DOGE for advice if necessary.
