IntelliJ IDEA supports running and debugging tests as well as navigation between tests and subjects or between a failed test and the fragment of code that caused the problem. IntelliJ IDEA integrates with Jest, Karma, Protractor, Cucumber, and Mocha testing frameworks.
Learn more from Debug JavaScript in Chrome. Note that IntelliJ IDEA supports debugging JavaScript only in Chrome or any other browser of the Chrome family. With the built-in debugger, you can debug both your client-side and server-side code and even run JavaScript code snippets in the interactive debugger console. IntelliJ IDEA also integrates with JavaScript linters and the Flow type checker. JavaScript-aware coding assistance includes completion for keywords, labels, variables, parameters, and functions, error and syntax highlighting, formatting, code inspections and quick-fixes, as well as common and JavaScript-specific refactoring. IntelliJ IDEA also supports React, Angular, Vue.js, and other frameworks and provides tight integration with various tools for web development. Gosu doesn't have the concept of a public static void main(String args) entrypoint.With IntelliJ IDEA, you can develop modern web, mobile, and desktop applications with JavaScript and Node.js. The using statement works with the following interfaces: In Gosu, you can use the using statement which will handle closing the Connection The using statement allows you to wrap sections of code that require connections to be closed toīe handled automatically when the block finishes. Rather, it uses the delegate field _runnable to implement theĭelegates give you a convenient way to favor composition over inheritance. Note that the class MyRunnable does not declare a run() method, as A delegate, exposed as the Impl property One interesting additional feature of Gosu is the ability to delegate the implementation of an interface to aĬlass variable using the delegate and represents keywords: Gosu classes can extend other classes and implement interfaces just like in Java, using theĮxtends and implements keywords respectively. SomeMethod( :enableLogging = true, :debug = false, SomeMethod(true, false, null, false, true) //bwah? Named arguments can be used to clarify code, so you don't end up with things like this: The for loop in Gosu allows you to iterate over both arrays and anything that implements Gosu supports the standard loop variants: for, while, do. , etc - Standard comparison semantics which also works on objects.= - Tests for object equality, just like.++ / - Just like the Java operators, except they cannot be used within another statement.Gosu supports the standard Java operators, with a few minor restrictions and some great bonuses: Var guess : String = null // Must declare the type because it can't be inferred Gosu is statically typed, but uses type inference to eliminate the vast majority of syntax overhead usually The Basics Variables and Type Declarations Check the README file for instructions or view the source.įor the truly impatient, you can evaluate some simple gosu expressions online over on the Play page.

It is noteworthy that Maven and Gradle projects do not require a local Gosu installation - the respective dependency resolution strategies will download the appropriate Gosu JARs from Maven Central.and MoreĪlternatively, a downloadable archive of simple command-line examples is available here. Run gradlew test to execute the JUnit tests contained within. Gosu also plays nicely with Gradle - here is another simple starter project. Run mvn test to execute the JUnit tests contained within. If Maven is your thing, here is a simple starter project. If you installed the old 3.X plugin, delete the plugin and remove the Gosu SDK (File > Project Structure > SDKs), the new plugin does not need it. The plugin is hosted on the IntelliJ IDEA Plugin Repository and you can download it directly from within If this is the case and you want to experiment with new features, use the Gosu Lab IDE instead (see instructions above). Keep in mind, however, the latest new language features may not yet be supported in the IntelliJ plugin. The Gosu Plugin for IntelliJ is the recommended way to use Gosu. Just select Life from the Examples pane and run the game by pressing F5.
You can try the bundled example projects like the Life game. Unzip the distribution zip, go to the bin folder and double click on gosu.cmd (or gosu if you are using Linux/Mac).Set the JAVA_HOMEenvironment variable to JDK 1.8's home, if needed.Gosu Lab is the easiest way to experiment with Gosu: There are several options to get started with Gosu depending on your needs Gosu Lab
