This curious little pattern can be helpful for certain problems that involve generics. We’ll look at what it is, and at a couple of use cases for it. What is it? The Curiously Recurring Generic Pattern (CRGP) is a pattern where a class TFoo derives from a generic class, using the class TFoo itself as… Continue reading The Curiously Recurring Generic Pattern
Best wishes to all fellow Delphi developers and the team behind Delphi! Let’s have some fun with FireMonkey! The little video above is a recording of a small (3D) FireMonkey app. You can test it out yourself by cloning our JustAddCode repo. There, you will find it in the HappyNewYear subdirectory. For those of you… Continue reading Happy New Year from Team Grijjy!
A while ago, I started a small series about trapping exceptions and turning them into an error report for consumption by your development team. This enables you to get information about errors that happen out “in the field”. The first part focused on the iOS platform and the second part on Android. In this part… Continue reading Build your own Error Reporter – Part 3: macOS Intel
The Grijjy Deployment Manager (DeployMan) is a tool to simplify the deployment of files and folders for iOS and Android apps written in Delphi. It is especially useful if you need to deploy a lot of files, such as 3rd party SDKs. Information and Usage The Deployment Manager (DeployMan) was first introduced in the blog… Continue reading Deployment Manager now Open Source
In this post, I will show you how to take full advantage of the GPU by creating custom shaders. Shaders are used in two places in the FireMonkey framework: for creating materials that you can apply to 3D objects, and for creating filter effects that you can apply to bitmaps. I will focus mostly on… Continue reading Introduction to Shader Programming
I present a small XML library that parses or creates XML documents with an extremely light-weight DOM that uses just 8 bytes per node. This post shows some of the interesting algorithms that make this possible. Another XML Library? I know what you are thinking: not another XML library! And you would be right, especially… Continue reading An XML DOM with just 8 bytes per node
Delphi 10.4 introduced Custom Managed Records. In this post we show how you can use this new language feature to wrap third party C(++) APIs in an easy to use model. We also compare this method to some other ways you may have interfaced with C(++) in the past. Ways to interface with C(++) For… Continue reading Wrapping C(++) APIs with Custom Managed Records
Is your Mac app a little unresponsive or does it feel sluggish? Does your MacBook laptop turn into a lap-heater when running your app? Then the new Metal support in Delphi 10.4 may be just the thing for you and your customers! I have been given permission by Embarcadero to blog about this new feature… Continue reading Boost Mac performance with Metal and Delphi 10.4
Say what now? In this post I will show you how you can use generics and class variables to generate unique incrementing indices for any Delphi type. For example, the Integer type could map to index 1 and the TStream type to index 2 etc. The values of these indices will be determined (partially) at… Continue reading Mapping Delphi Types to Indices at Compile Time
I have two anniversaries coming up this year. Delphi is turning 25 on February 14th, and I am turning another 25 the month after. So I think this is good time for an (overdue) personal introduction in relation to my 25 years of experience with Delphi, and with Pascal before that. Who knows, maybe you’ll… Continue reading 25 Years of Delphi and Me
