  1. PyScripter, an Open Source, freely available Python IDE written in Delphi, has reached 1 million downloads from Sourceforge. This is in addition to many millions of downloads from its earlier home at the now defunct Google Code and an unknown number of downloads from other distribution channels. Historic note: The initial motivation was to build a good scripting solution for Delphi applications. About 20 years ago Microsoft was still promoting ActiveX scripting and Windows Script Engines (such as vbScript and jScript) as the way of building scripting solutions for Windows applications (one of many Microsoft technologies that was all but abandoned). At that time Python was relatively unknown, but it so happened that it was available as a Windows Script Engine and I looked into it. I loved the clean syntax, the expressiveness and conciseness of the language. Other things I liked were duck typing, batteries included, strong object orientation (everything is an object) etc.. The first iteration was an IDE (editor/debugger) for ActiveX Script Engines. But there were many bugs and limitations of Active Scripting both on the Microsoft/Windows side and the Python side. I then came across Python4Delphi which at the time was maintained by a Canadian developer Morgan Martinet. I started contributing to that project and later become its main maintainer, when Morgan's interested shifted to other things. I also developed a simple Python IDE which was named PyScripter and was originally distributed alongside Python4Delphi. There was very few Python IDEs available at the time and somehow the project became known in the Python community and instantly popular. For me, developing PyScripter was just a hobby, but I received a lot of encouragement and kept on improving it. I was also making some income from donations and Google AdSense. Both PyScripter and Python4Delphi were later moved to Google Code. Python popularity was steadily increasing and at the peak of PyScripter's popularity around 2010, there were hundreds of thousands of downloads the days following each new release. More recently as we all know Python became one of the most popular programming languages, but at the same time there was strong competition to PyScripter from freely available commercial grade IDE's such as Jetbrains PyCharm and Microsoft's Visual Studio and Visual Studio Code. PyScripter was almost abandoned when Google Code closed down due to my frustration, but after a couple of years of inactivity the project was moved to Github and development resumed. Downloads are available through Sourceforge, since 2016. Through the years PyScripter has kept a large and loyal group of followers. I get many comments along the lines "I have tried VSCode, I have tried PyCharm, but I keep going back to PyScripter". PyScripter is also quite widely used in many Universities for introducing Python to students. And almost 20 years after its first release, PyScripter is still going strong...

    ANN: Parnassus Parallel Debugger

    A new IDE plugin aimed at helped debugging multithreaded apps! https://blogs.embarcadero.com/new-ide-plugin-parnassus-parallel-debugger/ The plugin: Displays all thread call stacks next to each other Lets you step over, run, etc a thread by itself, not the whole process Shows CPU usage by thread Editor integration to see where threads are executing, so you can easily see what other threads are in the same area of code and more... This has taken me five years to write! That said, most of that was downtime due to working too much time to spend time on this - this release is the result of working weekends since August. It's version 1, and I plan to add some more features over the next few months.

    Looking for SVG support in Delphi?

    In an earlier thread I presented an Interface-based access to native Windows (Direct2D) SVG support for Delphi applications. This has now been integrated into the SVGIconImageList components by @Carlo Barazzetta. Carlo is a kind of master of ImageLists (among other things). Have a look at his IconFontsImageList for instance. His SVGIconImageList component was based on the work of Martin Walter who must be a great programmer. His SVG component covered almost every SVG element and was well structured and cleanly written. There were numerous bugs and issues though, which, to a large extent, were fixed over the last few weeks and the code was refactored and optimized. Finally, @Vincent Parrett contributed a virtual version of the Image List, mirroring Delphi's VirtualImageList. So in its current form the component features: An SVGImageCollection component that inherits from Delphi's CustomImageCollection and thus is compatible with VirtualImageList A choice of SVG engines: the pascal one based on Martin's work which is using GDI+ and the native Windows one which is using Direct2D. Other SVG engines can be plugged-in with minimum effort. Excellent design support with a nice and effective SVGImageCollection editor developed by Carlo and the built-in VirtualImageList editor. Support for changing the opacity and color of the SVGs including using GrayScale. If you adopt Material Design for example and you use VCL styles, you can adjust the icon color to the style. Compatibility with older Delphi versions going back to XE6. It is free and open-source Svgs are vastly superior to bitmaps because they are typically tiny text files and scale perfectly. So, you do not need to ship with your application multiple resolutions of your images to match the DPI of the monitors. And there is a vast number of free SVGs to cover most needs. IMHO the combination of SVGImageCollection with Delphi's VirtualImageList is the best available solution (commercial ones included) for building DPI-aware Windows applications. Give it a try.
  4. Hi all, I just wanted to let you know my (long-awaited) FMX book is now available (actually it is rolling out on Packt and Amazon so availability may be different across different countries). If you like to read some details you can read my latest blog post: https://blog.andreamagni.eu/2020/10/book-delphi-gui-programming-with-firemonkey-now-available/ I really hope the book will be useful to spread Delphi and FMX as development platform. Thanks for the attention, Andrea
  5. In the attachment you can find a high-level interface-based encapsulation of the Direct2D SVG functionality. It allows you to parse SVG files and draw them to a GDI/GDI+ DC. Requires Windows 10 with Creators Update or later. Main form code to display SVG files: { TForm1 } procedure TForm1.FormCreate(Sender: TObject); begin fSVG := GetD2DSVGHandler.NewSvg; fSVG.LoadFromFile('..\..\browser.svg'); //fSVG.FixedColor := TAlphaColorRec.Red; //fSVG.Opacity := 0.5; fSVG.GrayScale := True; end; procedure TForm1.Paint; begin inherited; fSvg.PaintTo(Canvas.Handle, TRectF.Create(ClientRect), True); end; procedure TForm1.Resize; begin inherited; Invalidate; end; Features: Scale to any size Keep aspect ratio (optionally) Control opacity Recolor to any color Draw in gray scale Samples: The above in grayscale: Svg.zip
  6. I just had to do it... Go with the flow! It's the Black Friday / Cyber Monday "season", so I had to rush the book offer The book was actually scheduled for release in early December, but then the Black Friday deals started popping up all over the place... pressure was building... and I finally caved in! I cut the darn thing in two, and decided to offer Part I at a discount, and will give Part II for free to all Buyers. Not really a 97% BF discount but hey... Junior is still studying, and we still have to pay the bills (Corona doesn't help, either)! So, here it is! I hope you'll like it like you did Delphi Memory Management! https://dalija.prasnikar.info/delphiebap/index.html Thank you all for the support!
  7. I'd like to advertise the Sempare Template Engine for Delphi. The Sempare Template Engine for Delphi allows for flexible text manipulation. It can be used for generating email, html, source code, xml, configuration, etc. It is available on github via https://github.com/sempare/sempare-delphi-template-engine It is also available via Delphinus (https://github.com/Memnarch/Delphinus) Simply add the 'src' directory to the search path to get started. Sample usage: program Example; uses Sempare.Template; type TInformation = record name: string; favourite_sport : string; end; begin var tpl := Template.parse('My name is <% name %>. My favourite sport is <% favourite_sport %>.'); var information : TInformation; information.name := 'conrad'; information.favourite_sport := 'ultimate'; writeln(Template.eval(tpl, information)); end. Features include: statements if, elif, else statements for and while statements include statement with statement function/method calls expressions simple expression evaluation (logical, numerical and string) variable definition functions and methods calls dereference records, classes, arrays, JSON objects, TDataSet descendants and dynamic arrays ternary operator safety max run-time protection customisation custom script token replacement add custom functions strip recurring spaces and new lines lazy template resolution parse time evaluation of expressions/statements allow use of custom encoding (UTF-8 with BOM, UTF-8 without BOM, ASCII, etc) extensible RTTI interface to easily dereference classes and interfaces (current customisations for ITemplateVariables, TDictionary, TJsonObject) There are numerous unit tests that can be reviewed as to how to use the various features. Happy for all to play with it. Released under GPL and Commercial License. Any feedback welcome.

    Delphi 10.4.1 and the IDE FIx Pack

    tbh not having IDEFixPack being available is good in the long run - with the existence of it nobody (or very few) actually cared to report issues and put some pressure on Embarcadero to address these things. Now that there is no solution available the pressure on Embarcadero has raised and I can confirm that they are working on it - will they suddenly implement all fixes and optimizations from Andreas? No, but better they do slowly than relying on the third party no matter how incredible.

  20. Hello, here's a small Christmas present for you: There is a new release 6.0 of DEC - Delphi Encryption Compendium available, or put otherwise: DEC is back on track! 😉 The release can be found here: https://github.com/MHumm/DelphiEncry...eases/tag/V6.0 What is DEC? DEC is the Delphi Encryption Compendium open source library, a library containing cryptographic algorithms of the following categories: hash algorithms encryption algorithms key deviation functions CRC cryptographic pseudo random number generator format conversion classes What's new in V6.0 compared with the 5 year old V5.2 release? A complete list can be found in the last chapter of the included documentation. Supports D2009 - 10.4.1 Sydney Cross platform compatible if you turn off use of ASM in DECOptions.inc the hard to understand test program got reworked into unit tests test coverage got increased some bugfixes, like fixing the XTEA encryption algorithm or the included KDF2 turned out to be KDF1 instead implementation of the newest Whirlpool hash algorithm version implementation of KDF1, KDF2 and KDF3 key deviation algorithms changed unit structure to be more modular and better maintainable added some demo applications. The two FMX based ones are even available from Google Play (stemming from an earlier commit) added a 40+ A4 sized pages documentation most methods contain XMLDOC comments now So is it all over now, or are there plans for the future? Of course I know that this release didn't bring much new algorithms. But as far as my time allowes development shall continue (further project members are welcome!) I do have some plans for V6.1: Add the SHA224 hash, this is still missing Add SHA3 Add GCM block chaining mode for ciphers Add a first pasword hash algorithm, most likely bcrypt So much for today 😉 Cheers TurboMagic

    How do I enumerate all properties of a Variant?

    Yes, you can. Basically, you have to call GetTypeInfoCount(), GetTypeInfo(), GetTypeAttr() and other functions (All documented by Microsoft). Here is a function to list all method names including property getter/setter. Similar code can enumerate argument list, argument data types and return value data type. procedure DisplayMethodNames( const DispIntf : IDispatch; const IntfName : String; Strings : TStrings); var Count : Integer; TypeInfo : ITypeInfo; TypeAttr : PTypeAttr; FuncDesc : PFuncDesc; HR : HRESULT; I : Integer; FuncName : WideString; begin if IntfName <> '' then Strings.Add(IntfName); Count := 0; HR := DispIntf.GetTypeInfoCount(Count); if Failed(HR) or (Count = 0) then Exit; HR := DispIntf.GetTypeInfo(0, 0, TypeInfo); if Succeeded(HR) and (TypeInfo <> nil) then begin TypeAttr := nil; HR := TypeInfo.GetTypeAttr(TypeAttr); if Succeeded(HR) and (TypeAttr <> nil) then begin for I := 0 to TypeAttr.cFuncs - 1 do begin FuncDesc := nil; HR := TypeInfo.GetFuncDesc(I, FuncDesc); if Succeeded(HR) and (FuncDesc <> nil) then begin TypeInfo.GetDocumentation(FuncDesc.memid, @FuncName, nil, // DocString, nil, // HelpContext nil); // HelpFile if Length(FuncName) <> 0 then Strings.Add(Format(' %-3d %s', [I, FuncName])); TypeInfo.ReleaseFuncDesc(FuncDesc); end; end; TypeInfo.ReleaseTypeAttr(TypeAttr); end; end; end;

    Turbo SynEdit & Font Ligatures

    Development of SynEdit at PyScripter has been moved to and merged with TurboPack SynEdit. The focus of the development is to modernize the code base and enhance the functionality (sometimes at the expense of backward compatibility). In addition to the earlier enhancements and fixes two more features have been recently added: Per-monitor DPI awareness Support for Font Ligatures (new option eoShowLigatures) Fonts like Cascadia Code and Fira Code contain ligatures relevant to programming. See this article for details. Are you using font ligatures? Do you like them? See sample. Thanks to vhanla for contributing the ligature support.

    Looking for SVG support in Delphi?

    I want to personally thank Vincent Parrett and Kyriakos Vlahos for the great contribution to the project! The official 2.0 version will be released shortly and also published on GetIt. Meanwhile, you can download the project from Github and report any problems. I'm also working on IconFontsImageList to add similar funcionalities, like a IconFontsVirtualImageList and IconFontsImageCollection...
