Clerk is a notebook library for Clojure that enables interactive, reproducible, and version-control-friendly live programming. Notebook content is written in standard Clojure namespaces or Markdown with embedded Clojure code blocks and evaluates top-to-bottom for predictable behavior. Clerk notebooks are either regular Clojure namespaces (interspersed with markdown comments) or regular markdown files (interspersed with Clojure code fences). This also means Clerk notebooks are meant to be stored in source control. Clerk notebooks always evaluate from top to bottom. Clerk builds a dependency graph of Clojure vars and only recomputes the needed changes to keep the feedback loop fast.

Features

  • Uses ordinary Clojure namespaces or Markdown files—no special formats
  • Editor-agnostic: you can continue using your preferred editor
  • Enforces ordered execution to avoid notebook-state confusion
  • Builds a dependency graph to re-render only changed parts
  • Runs inside the same Clojure process as your code—no external tooling required
  • Enables rich, local-first notebook-style presentations and visualizations
