Fregure

Experiments in Frege and Clojure integration

Frege + Clojure = 😍

Installation

git clone https://github.com/yurrriq/fregure.git

Usage

Run the Frege compiler and then run the Clojure application:

lein do fregec, run

Hello from Clojure!
Hello from Frege!

You can also package up all the Clojure and Frege code and their runtimes:

lein uberjar

calling: javac -cp ...
Compiling fregure.core
Created /path/to/project/target/uberjar+uberjar/fregure-0.1.0-SNAPSHOT.jar
Created /path/to/project/target/uberjar/fregure-0.1.0-SNAPSHOT-standalone.jar

That produces a JAR file which you can run:

java -jar target/fregure-0.1.0-SNAPSHOT-standalone.jar

Hello from Clojure!
Hello from Frege!
