A fast Clojure/Cljs REPL and a minimalist build tool with zero configuration, as a standalone uberjar.
Why learn another build tool when you can code on the REPL with zero configuration?
The node-based, blazing fast (~10x) Browser, Rhino, Nashorn, and Node repls are bundled in Clojurescript. This library exposes these build tasks as plain old functions on the repl. In addition it maintains compatibility with leiningen project maps, and provides utilties to manage runtime classpath and dynamic dependencies using alembic.
Assuming you installed Java8, rlwrap (optional), and downloaded replify.jar, start a REPL:
rlwrap java -jar replify.jar
user=> (use 'replify.core)
On an Intel i7-7500U CPU @ 2.70GHz and 32GB Ram, with Ubuntu 17, this repl launches instantly. From here you can perform common Cljs tasks.
For lightweight scipts under 'src' add the classpath, like this:
rlwrap java -cp 'replify.jar:src' clojure.main
All tasks assume your current cljs/cljc source files are under src.
user=> (use 'replify.core)
user=> (build 'foobar.core)
user=> (build-on-node 'foobar.core)
... node main.js
user=> (start-node-repl)
user=> (start-rhino-repl)
user=> (start-brepl)
user=> (release 'hello.core)For browser REPLs: Create an index.html at the project root and include (:require [replify.core :as repl]) in your main source file.
<html>
<body>
<script src="target/app.js" type="text/javascript"></script>
<div id="app"> </div>
</body>
</html>Refresh browser at localhost:9000 for brepl to connect.
To manage dependencies, create a project.clj in the current directory. Replify
wraps leiningen but you don't have to install it.
