Minimal

A minimal CLJS project for demonstrating the protocol issues with CLJS r1978.

How to use it

Clone the project

git clone https://github.com/magomimmo/minimal.git

Compile the project

lein compile
Compiling ClojureScript.
Compiling "dev-resources/public/js/whitespace.js" from ["src/cljs" "dev-resources/tools/repl"]...
Successfully compiled "dev-resources/public/js/whitespace.js" in 11.199011 seconds.

Run the ring server

lein repl
Compiling ClojureScript.
nREPL server started on port 50868 on host 127.0.0.1
REPL-y 0.2.1
Clojure 1.5.1

Launch the brepl

You now have two options to launch a browser connect REPL:

• using the traditional lein trampoline cljsbuild repl-listen
• using the piggieback lib by Chas Emerick

Traditional

Open a new terminal windows, cd in the main project directory, and issue:

lein trampoline cljsbuild repl-listen
Running ClojureScript REPL, listening on port 9000.
"Type: " :cljs/quit " to quit"

With Piggieback

If you use the Piggieback lib, you do not receive any warnings.

Evaluate the following expression from the the REPL where you ran the ring server:

user=> (browser-repl)
Type `:cljs/quit` to stop the ClojureScript REPL
nil
cljs.user=>

Activate the brepl connection

Visit the localhost:3000 url, wait a moment for the connection to be establish and start BREPLing.
