Complete local setup development guide for Konveyor Analyzer-lsp 🚀

Build, test, and develop Kantra rules locally with full JDT-LS and multi-language provider support. Some content in this post was generated using an LLM.

Modernizing large, complex codebases is a significant challenge. Identifying migration blockers, deprecated APIs, and technology-specific patterns requires deep, accurate code analysis. The Konveyor Analyzer LSP is engineered to solve this problem by providing a flexible and powerful static analysis engine. It uniquely leverages the Language Server Protocol (LSP) to tap into rich, IDE-level code intelligence for multiple languages.


My first 6 hours with Rust

TLDR; I took a day off from work today, although still most of my time I ended up doing my travel expenses. Talk about priorities. I am the one to blame here totally. 😄

So come around lunch time, thats when all the fluids are ready to do something different. I ended up exploring some basics about Rust. I heard a friend once said, if a prominent person (wonder who that is..) says billions over and over again, somehow people just start believing in billions. Anyways I am totally sold by my youtube feed to explore this a bit. What is this rust thing? And before I go any further, just to let you know I like programming languages and problem solving. I am not hung up on one language. I appreciate them all. Except MS access (oops)


Think in Graphs, Not Just Chains: JGraphlet for TaskPipelines 🚀

JGraphlet is a tiny, zero-dependency library for building task pipelines in Java. Its power comes not from a long list of features, but from a small set of core design principles that work together in harmony.

At the heart of JGraphlet is simplicity, backed by a Graph, Add Tasks to a pipeline and connect them to create your graph. Each Task has an input and ouput, A TaskPipeline builds and executes a pipeline while managing the I/O for each Task. For example a Map for Fan-in, a Record for your own data model etc. A Taskpipeline also has a PipelineContext to share the data between Tasks, and furthermore Tasks can also be cached, so the computation doenst need to take place again and again. You can choose how your Task pipeline flow should be, and you can choose whether it should be a SyncTask or Async. By default all Tasks are Async.


Neovim for Java Developers: A Match is made 🚀

Are you a Java developer who is mesmerized by the power and efficiency of Vim? Do you want to try your development experience to the next level? I mean hands-off the mouse style! If so, you’re in for a treat! In this post, I am going to dive into the world of Neovim and explore how you can transform it into a Java IDE. To be honest its a learning journey. And the more I experience learning it, I feel like I really need to share how cool this thing really is!


Static Code analysis tutorial with Konveyor and Kantra part - 1

Konveyor Kantra CLI is a command-line tool for analyzing and transforming application source code to aid modernization and migration. It performs static code analysis to detect issues. Kantra can also extract metadata, generate deployment assets (e.g., Kubernetes manifests), and runs via containers or natively. It supports multiple languages e.g. Java, Go, .Net and Node.js and integrates with CI/CD pipelines. Kantra is the foundation for automated, LLM-powered app modernization workflows like Konveyor AI (Kai).
