Adding Rust Support and Some Major updates to My Neovim Config

Mon, 09 Mar 2026 00:00:00 +0000

It’s been about 8 months since my last update on neovim4j, and the config has evolved significantly. The name “neovim4j” is now a bit of a misnomer—while it started as a Java-focused setup, it’s grown into a polyglot development environment.

Rust Support 🦀

The biggest addition is comprehensive Rust support. I’ve integrated:

rustaceanvim for advanced LSP features powered by rust-analyzer
crates.nvim for smart Cargo.toml management and dependency completion
codelldb debugger integration
neotest for running Rust tests directly in the editor

The Rust setup mirrors the Java tooling quality—full LSP, debugging, and testing all working seamlessly. Semantic highlighting is disabled in favor of Treesitter for more colorful syntax highlighting.

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!
