# ev3nrepl

Run clojure on your EV3!

## Usage

### Requirements

- A Lego Mindstorms EV3 (obviously)

- A 2GB micro SD card

- leinigen (probably some variant of 2)

- [lein-shell](https://github.com/hyPiRion/lein-shell) for ease-of-use

### Setting Up

First off, you need to follow the instructions found on the

[leJOS sourceforge wiki](http://sourceforge.net/p/lejos/wiki/Creating%20a%20bootable%20SD%20card/)

for installing the leJOS kernel onto your SD card so you can boot your

EV3 into the leJOS operating system.  Once you have all that working,

and you are connected to your EV3 via USB cable or via wifi, you just

need to clone this git repository, then run `lein uberjar` and (if

connected via USB) then `lein pushev3`.  If

you're connected via wifi, then you should scp the uberjar which

should be `target/ev3nrepl.jar` onto your EV3.

Now, ssh into the EV3, and run `jrun -jar ev3nrepl.jar`.  Now, wait.

The jvm takes a bit of time to start up on the EV3 and a clojure repl

takes longer still.  In my (limited) experience it usually takes about

1-3 minutes (I haven't timed it, okay?).

After a sufficient amount of time has elapsed, you should be able to

connect to an nrepl running on port 19324 on your EV3.  As part of

it's boot into the leJOS system it should have displayed it's IP

address.

Happy roboting!
