uclj

A small, quick-starting, native Clojure interpreter.

It is built on top of the Clojure JVM runtime, but the parts that need dynamic class loading have been reimplemented in Clojure so that it could be compiled into a native application.

Features

• Starts quickly (it is compiled with GraalVM native-image)
• Small (<1K SLOC)
• Out of the Box core.async support and also many other core libraries

Usage

Download the binary from the Release page and run the uclj command:

• call uclj without parameters to get a REPL
• call uclj filename.clj to load a file
• call uclj filename.clj --test to load a file and then run all test cases in it
• call uclj '(...)' to evaluate a Clojure expression. (It must start with a ( character.)

Build

You can also build the binary yourself. You will need Leiningen and GraalVM to build the application. Set the GRAALVM_HOME environment variable and run the build-graal.sh script.
