If we want to transform items in a collection we can use the map method. If we also want to use the index of the element in the collection in the transformation we must use the mapIndexed method. We must provide a lambda function with 2 arguments, where the first argument is the index of the element in the collection and the second argument is the element in the collection.
Kotlin adds a lot of useful extensions to the collection classes. One of them is the indices property. The indices property returns the indices of the elements in the collection as an IntRange.
The JVM Test Suite plugin is part of the Java plugin and provides a nice way to configure multiple test types in our build file. Even if we don’t have multiple test types we have a default test type, which is used when we run the Gradle test task. Using the test suite DSL we can configure the task of type Test that belongs to a test suite type. The current release of the JVM Test Suite plugin provides a single target for a test suite type with a single Test task. This will probably change in future releases of the plugin so more task of type Test can be created and configured.
In C# version 10, support for file scoped namespaces was added. This allows us to eliminate more boilerplate from our classes and also get rid of some extra unneeded identation. Unfortunately, when you create a new C# class in Visual Studio 2022, the template still uses the old namespace declaration style. I don’t like that, and if you found this blogpost, neither do you!
Thankfully, changing this is not hard.
The version catalog in Gradle is very useful to have one place in our project to define our project and plugin dependencies with their versions. But we can also use it to define our project version and then refer to that version from the version catalog in our build script file. That way the version catalog is our one place to look for everything related to a version. In the version catalog we have a versions section and there we can define a key with a version value. The name of the key could be our project or application name for example. We can use type safe accessors generated by Gradle in our build script to refer to that version.
The JVM Test Suite plugin adds an extension to our build that allows us to configure test tasks. We always can access the default test task and for example specify the test framework we want to use. Gradle will then automatically add the dependencies of that test framework to the testImplementation configuration. If we want to add more dependencies to the testImplementation configuration we don’t have to do that by explicitly mentioning the testImplementation configuration. Instead we can also use a dependencies block from within the JvmTestSuite extension. Any extra dependencies we need to run our tests can be added using the configuration names without a test prefix. Gradle will automatically add them to the correct test configuration for us so the dependencies are available when we compile and run our tests. This will also work for any other new test type we add to the test suites, e.g. for integration tests.
In a previous post we learned we can turn a string into a string with kebab casing using dasherize from the dw::core::Strings module. If we want to turn a string into a string with camel casing we can use the underscore function. The underscore function will replace spaces, dashes and camel-casing with underscores, which makes the result snake-casing. Any uppercase characters are transformed to lowercase characters.
When running Keycloak it can be useful to log events like a login or logout event using the jboss-logging event listener. This is a built-in event listener that will use JBoss logging to log events. For example we can configure our JBoss logging to log to the standard output streams and when we run Keycloak we can see in the console output details about events when they happen. The event listener jboss-logging is enabled by default for a realm. We can check it from the Events Config page where it is listed in the Event Listeners field.
In a previous post I’ve shown how to build a minimal example of a random case class generator using the metaprogramming features of Scala 3. While investigating this topic, I naturally came upon multiple ways to do this. In this post I will elaborate on two other ways to build the same generator and pick my personal favorite.
Spock is an awesome test framework for testing our Java or Groovy code. Spock itself is written with Groovy and provides a nice syntax to define our tests, or specifications in Spock terminology. To configure support for using Spock in our Gradle build is very easy with the JVM Test Suite plugin (included with the Java plugin). The plugin gives us a nice syntax to define different types of tests, for example integration tests, with their own source set, dependencies and configuration. To use Spock as testing framework we only have to use the method useSpock within a test configuration. The default version of Spock that is used is 2.1-groovy-3.0 when we use Gradle 7.6. If we want to use another version we can use a String parameter when we use the useSpock method with the version we want to use.
