Secure your app’s resources with a new algorithm
When generating .4dz files, 4D uses a standard zip format by default. If you are a software publisher, you’ll be happy to know that 4D v19 R2 added a feature that allows preventing users of your application from seeing the content of the 4DZ, and therefore from being able to modify it.
How to take advantage of GitHub actions with 4D
Your project is now on a source control system. This means that managing several versions of your software, monitoring changes, and integrating corrections or new features is much simpler now.
Why not also take advantage of continuous integration?
Starting with 4D v19, you can launch the compilation of your project with a command. As a result, you now have all the building blocks needed to automate your integration chain.
This blog post will give you an example of automation with the GitHub manager and GitHub Actions.
How to automate the compilation
Since 4D v19, you can start the compilation of a project with a simple command. You might be wondering what you can use this for!
Your team may consist of several developers, so why not automate the compilation at each code push on your source control server? It is always easier to identify an error when it is quickly detected.
Another case is when your project consists of several components. You can write a method that compiles, builds, and then copies the component to the host database.
This blog will discuss the different technical points that are very useful to create your own automation tools, along with an example application.
Toggle Dark & Light Mode on macOS in one click
As of 4D v19, you have the possibility to create applications that support the Dark and Light mode on macOS. To do this, you have to modify and check many small details: icons, widgets, texts, background colors, etc.
As a result, you need change the appearance of your mac dozens of times per hour. OK, you might be thinking, “What? All it takes is three clicks. Open the preferences panel, click the general icon, then the light or dark control, that’s it!“. But honestly, if you are a developer or a tester, repeating these actions over and over again becomes very tedious.
Show online documentation directly from the code editor
In the latest versions of 4D, several improvements have been made to simplify the writing of code with classes:
- function and attribute suggestions according to type
- display of the prototype with a short description
With 4D v19 R2, you can open the online documentation of a function with a single action.
Go Mobile with 4D: Generate Android and iOS apps from a Single Project
We are pleased to announce that 4D for Android is available with 4D v19 R2.
Many features are already available, and with each new release, we’ll enrich the possibilities so that 4D for Android’s features match those of 4D for iOS.
What’s best is that the same mobile project can generate both native iOS and native Android apps. We made sure to provide very similar user experiences on both platforms while still respecting their standards.
how to extend your application and go mobile
The mobile project editor is fully integrated into 4D. You can design and build native iOS and Android apps quickly and easily without programming. If you want to go further, you can open the generated application with Android Studio or Xcode and customize it with Kotlin or Swift.
The other big advantage of a native application is that you can access the data even when you’re offline.
CSS Media query for a dark or light UI
Dark mode has been gaining a lot of ground recently. That’s why we’ve added support for it in 4D v19, and mentioned a few ways you can adjust it to your needs in the related announcement.
In this blog post, we’ll focus on CSS and explain in detail how to set CSS styles for light and dark modes using CSS media queries.
Launch a compilation by programming
In continuous integration systems, every time code is submitted, or on an hourly basis, a compilation of the source code is automatically launched. This approach allows you to check merges on the code management server.
Starting from 4D v19, a new command allows you to launch code compilation, so you can set up this type of system.
Code Editor: Multiple themes, your choice!
The code editor’s feature set grows with every release, and 4Dv19 is no exception.
Every developer has their own special – and sometimes peculiar – taste when it comes to their code editor (font, font size, color of the elements, etc.). What looks great and boosts productivity for one developer can be an obstacle for another. That’s why 4D v19 introduces theme management.
If “creating my own theme” is on your bucket list, now is the right time to check it off! 4D v19 comes with basic themes that you can enrich and adapt to your own taste.
Easily Manage your Application’s Information
To build your application, you use the BUILD APPLICATION command with a set of XML keys that allow you to configure the built application. For most of you, this option is enough for application building. However, we want to make sure we meet your specific needs too, so we’ll simplify the BUILD APPLICATION command by splitting it. This will allow for more flexibility while creating applications.
