Prompt: Can I Claude Code build from command line via MSBuild and the analyze the ouptut of the Delphi compiler/msbuild? The compiler is located in c:\Delphi\Delphi 13\bin\dcc32.EXE but I would prefer to pas the dproj file to MsBuild. I think MsBuild is installed here: c:\Windows\Microsoft.NET\Framework64\v4.0.30319\MSBuild.exe Answer: this requires the user to enable the WSL Interop […]

FuzzyStringCompare calculates an approximate similarity percentage between two strings. It uses a heuristic to count matching characters that are roughly in similar positions, allowing for a tolerance based on string lengths. The tolerance is about one-third of the longer string’s length plus the length difference. The algorithm greedily matches characters from the shorter string to

Intro Following a glorious review by a guy on Delphipraxis I decided to test Claude Code which was sold there as the ultimate productivity tool for Delphi (1h of development with Claude valuing as much as a whole day of alone programming). With hopes low (from my previous experience with AIs), I decided to perform

I have this weird bug in Delphi 13 FMX where the height of the controls is not correct, at app startup. procedure TForm1.AfterConstruction; begin inherited AfterConstruction; MakeDemoBubble; end; TAutosizeBoxText (based on TRectangle) is parented in a ScrollBox. It is set to Align=Top. procedure TForm1.MakeDemoBubble; begin mmoUserResponse.Text := ‘WhatsApp-like text bubble. ‘ + #13#10+ ‘Cool and

I travel around 2000Km per year with my bicycle. And what can be better than 2000Km? 4000Km 🙂 So, I will attempt to attach a solar panel to my bicycle to replenish the battery (at least partially). Solar panels efficiency Typically ranges from 150-250 W/m² under peak sunlight. High-end panels hitting 220-300W/m². Factors Influencing Output

“Free Code Agent: Build Faster Right in Your RAD Studio IDE” Presented by Yai (CTO at Solutions, Embarcadero MVP) Core Idea * AI Code Agents are tools that accelerate coding tasks by generating, refactoring, and scaffolding code inside your IDE. * They do not replace developers; they augment productivity. * Example used: Gemini CLI
Maker AI: The Ultimate AI Ecosystem for Delphi (Version 3.0) Presented by Gustavo Enriquez Core Problem * AI integration is fragmented: Multiple APIs (OpenAI, Gemini, Claude, LLaMA, Grok) each with unique SDKs and syntax. * Leads to high dependency and code obsolescence when models change. * Delphi developers need stability and longevity, not constant
CodeRage 2025 was an amazing event. I created a short summary of the CodeRage Day1 presentation for my future reference. Then I thought that it might be useful for others also so I will post it here. This is time consuming… if possible I will summarize the other days also. The text is generated with

Note: This is an excerpt from my “Delphi in all its glory [Part 2]” book. Find the full chapter there.

The memory management in Delphi is unique because ALL memory is

Android’s lifecycle model is a mess. The OS freely kills your process whenever it needs RAM, and you—the app developer—are expected to deal with the fallout. Android shifts its memory problems onto the app layer, leaving you to rebuild your internal state because the OS felt like freeing 200 MB. FireMonkey tries to give you

A stackOverflow user wanted to know why clicking on the form’s close button while some FOR loop is running does nothing: procedure TForm1.Button1Click(Sender: TObject); var i: Integer; begin for i := 0 to 9999999 do begin Memo1.Lines.Add(‘hi’); Application.ProcessMessages; end; end; The issue comes from the lack of understanding of how the forms work. Here is
The {$PUSHOPT} and {$POPOPT} directives introduced in Delphi 13 are used to save and restore the current set of compiler options and warning configurations. Useful when we want to include .inc files or code sections that might alter compiler settings, and we want to ensure that these changes do not affect the rest of your

NameOf is a magic function introduced in Delphi 13. What it does is return the identifier name of a symbol (routine, variable, etc) as a string, as resolved by the compiler. It can be used for: Consistent naming Its main advantage is that if we later rename the function, the compiler forces the change

When I upgrade to the next Delphi version, instead of re-configuring the IDE from zero, I usually “port” the settings from the old version to the new version. For this: I extract some registry keys to text (reg) files In each file I (batch) replace the old version to new version (for example “21.0” to

I needed (for a project I am working on) to obtain the default language for the operation system. Preferable it should be in “human” format like “English” instead of “En-US”. The AI lead me to strange paths. In the end it tuned out to be quite easy so I created these two function (now part

I’ve seen JavaScript developers complain that every few years they’re forced to switch frameworks. Angular, React, Vue, Svelte… each one promising stability, then slowly fading out while the next shiny thing takes over. It’s a cycle of rewrites, migration guides, and “deprecated” warnings. And it hit me: I’ve been really lucky with Delphi.While others wrestle

If you place the cursor on an identifier (variable/function name/etc), CnPack will show you where that identifier is used in your code. Look for example how easy is to spot where the FBuffPos variable is used in the code below: Also, see how “dangerous” instructions (“Exit”) have been marked in blue! Note: On your Delphi

Here is the trick: Go to Preferences->Multi-instances->Default (mono-instance). Close notepad++ Go to “c:\Program Files\Notepad++” and create there an empty file called “asNotepad.xml” (of course, you will need Admin privileges for that). Result: When you double click a TXT file in Explorer, Notepad++ will open and show that new document in its own window/tab.

I’ve seen this trend where AI lacks (compared with other languages) when you try to use it for Delphi (VCL). Probably not their fault. Probably because of lack of code on GitHub…. 😞 Initially, I thought it was only an impression, but later tests (for example, generating a full program with Replit in Delphi and

Delphi is great for RAD. We all love Delphi, even when we are mad at it. In my opinion Delphi has 3 issues that Embarcadero has to fix in order to make Delphi more attractive. 1. It has ACTIVELY work to bring new Delphi programmers. 2. Solve the problems with the IDE stability 3. Has

I haven’t nailed down a favorite AI yet. Copilot’s at the bottom of my list—it churns out the worst Delphi code and gives answers so short they’re borderline useless.

Locating BPL dependency failure In one instance my package required another package, but its BPL was not present. The error I got was “Can’t load package xyz.bpl. %1 is not a valid Win32 application”. I used the Dependency scanner feature from ‘PE Explorer’ ( www.heaventools.de ) to detect this. There was supposed to be

Recently, I came across a forum where somebody described FreeAndNil as an “abomination” and I think that’s a bit over the top. Let’s unpack this topic ca refully, with technical clarity and an eye for proportion.

In FMX, unlike the VCL, the Visible property affects both design time and runtime when set in the Object Inspector. That’s why setting Visible:= False in FMX hides components in the Form Designer, which is a big inconvenience. If you edit the form at design time often, you can keep Visible:= True in the designer
Under FMX, TComponent.Visible effects also the design time! Read More »
VCL had a nice and uniform message box system. Most important (and convenient), the messages were blocking. Because of the Android platform which does not support asynchronous messages, all this is gone. So I document here the behavior of few different ways in which we can display message boxes in FMX. None is perfect (not
