The Wielder plugin is a game-changer for Obsidian users who want to harness the power of Clojure directly within their documents. With Wielder, you can write code blocks marked as `clojure` and have them automatically run in view mode, allowing you to build complex pipelines and data visualizations without leaving Obsidian. The plugin also enables rendering React components with Reagent, making it possible to create interactive applications straight from your markdown files. Additionally, Wielder provides direct access to the Obsidian API, giving you unparalleled flexibility and control over your notes.
