![]() $ jbang -verbose init gh.java "connect to GitHub and fetch all repositories under jbang and collect how many stars they have" Or to fetch information and process it further: $ jbang init jokes.java "print a random chuck norris joke fetched from the API service providing free jokes API." Other mundane tasks, for example calling a REST API via a Java Client and showing the results, have become single-line commands. The text " Write." requests to create a Java program that uses OpenCV.The init ImageProcessor.java argument will create a new ImageProcessor.java file in the directory where the command executes.The -preview argument for using preview features, e.g., ChatGPT.$ jbang -preview -verbose init ImageProcessor.java "Write a Java program that processes an input image and add text Hello world on it using OpenCV to produce an output image called output.png" Usually, anyone learning OpenCV in Java would need to know the intrinsic details of image processing and its components and concepts to understand dependencies before even beginning to write any code. In the following example, the command creates Java code that takes an image, adds text, and then writes it to the filesystem. The enhancements introduced also bring some exciting ergonomics, e.g., a developer doesn't necessarily need to figure out all the intrinsic details of an API. Furthermore, it will allow Java developers to use the preview features like String templates. The command will download the early-access release of OpenJDK 21 in case there isn't one on the system. $ jbang -java 21 -enable-preview -c 'print(STR."First arg is \!")' JBang To use JBang with Java 21 preview features, simply run the following command: Furthermore, developers can also request via CLI to generate code with OpenAI’s ChatGPT or even create plugins in Java for ChatGPT. ![]() Java developers can now execute Java code with JBang using the upcoming release of Java 21, scheduled for September 19, 2023. It was developed to simplify the execution of Java code more interactively and conveniently, similar to languages like Python. ![]() JBang is a lightweight Java-based scripting tool that allows developers to write and run Java code directly from the command line without requiring an entire Java project or compilation steps. JBang has also recently introduced the integration of ChatGPT via the CLI, allowing developers to create JBang scripts using ChatGPT. You can view the results here and the full benchmarking code here.The latest JBang release provides a preview of Java 21 and more integration with the OpenAI plugin via the quickstart port to Java. We had a bit of difficult showing beneficial results for async and still unsure whether these results are a good reflection of the benefits of async. If you want a batteries included and ops-free experience, try out Shuttle. Maybe await a future post digging deeper into async in Rust! Shuttle: Stateful Serverless for Rustĭeploying and managing your Rust web apps can be an expensive, anxious and time consuming process. This post is a introductory look into writing async Rust. gives a good overview of the status of async language features and other things in the async ecosystem. The async side of the Rust language is still in heavy development and can only can get better from here. If you want to read more about writing async the there is the official Rust async book and Tokio has a brilliant tutorial. To keep this post short and to the basics we will stop here. The above code starts both requests and then waits for the response from both, joining them in a resulting tuple. Rather than getting weather then getting the news. get ( "" ) let (weather, news ) = tokio :: join! (weather, news ). = 100 to Cargo.toml (or if you have cargo-edit installed: cargo add tokio -F full)
