This week is Delphi’s 27th anniversary and the team here at Grijjy is excited about all the great things that have happened over the past year in the Delphi world. Just seeing the thousands of attendees this week for the Delphi 27th webinar was amazing, but we can really feel the growing momentum in the… Continue reading Delphi’s 27th anniversary! Startup settings and parameters revisited
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
Delphi is known for its fast build speeds, at least for Win32 apps. But when you compile your same FireMonkey app for other platforms, the build time increases dramatically and can be up to 15 times slower. Granted, it is still much faster than most C++ compilers, but when you are used to blazing fast… Continue reading Decrease Your Build Time
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
In this 3rd part in (what turns out to be) a series about Custom Managed Records, we take a look at how they can be used to create smart pointers. About Smart Pointers But first we have to get some terminology straight. Smart Pointers is an umbrella term behind different technologies for making it easier… Continue reading Custom Managed Records for Smart Pointers
There are those common try..finally blocks that you write over and over again. For example entering and leaving a critical section to protect resources from multiple threads, or calling BeginUpdate and EndUpdate to efficiently bulk-update a FireMonkey control. These kinds of “restorable” operations can be automated with the new Custom Managed Records feature introduced in… Continue reading Automate Restorable Operations with Custom Managed Records
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
