[![Coverage Status](https://coveralls.io/repos/bfontaine/lein-fore-prob/badge.png)](https://coveralls.io/r/bfontaine/lein-fore-prob)

A leiningen plugin which given a problem from 4clojure will populate the

current project’s tests with the problem’s tests. This is based on

[`lein-foreclojure-plugin`][lfp] code updated for Leiningen 2.

[lfp]: https://github.com/broquaint/lein-foreclojure-plugin

## Usage

Add the plugin in your `~/.lein/profiles.clj`:

```clj

{:user {:plugins [ ; ... other plugins ...

                  [lein-fore-prob "0.1.3"]]}}

```

Create a project to store 4clojure problems:

```

lein new probs-from-4clj

cd probs-from-4clj

```

Then use the plugin:

```

lein fore-prob [open]  [ ...]

```

You can use multiple problem ids at the same time. Use the `open` subcommand to

open these problems in a browser instead of adding it to the current project.

## What’s added

Given a new project like this:

	.

    ├── ...

    ├── project.clj

    ├── src

    │   └── probs_from_4clj

    │       └── core.clj

    └── test

        └── probs_from_4clj

            └── core_test.clj

A stub function will be added to `src/probs_from_4clj/core.clj` e.g for

[problem 98][98] an `equivalence-classes-solution` function is defined. Then in

`test/probs_from_4clj/core_test.clj` the tests for that problem will be added

e.g. again for [problem 98][98] the test would be `can-equivalence-classes`. At

that point you can flesh out the function until the test passes then copy

it over to [4clojure.org][4clj] when you’re happy with it.

[98]: http://www.4clojure.com/problem/98 "98. Equivalence Classes"

[4clj]: http://www.4clojure.com/

### Example

Here is what `lein fore-prob 43` would add:

```clj

;; in src/your-project/core.clj:

;; problem 43 (Medium)

(defn reverse-interleave-solution

  [& args] ;; update args as needed

  ;; Write a function which reverses the interleave process into x number of subsequences.

  nil)

;; in test/your-project/core_test.clj:

;; problem 43

(deftest can-reverse-interleave

  (is (= (reverse-interleave-solution [1 2 3 4 5 6] 2) '((1 3 5) (2 4 6))))

  (is (= (reverse-interleave-solution (range 9) 3) '((0 3 6) (1 4 7) (2 5 8))))

  (is (= (reverse-interleave-solution (range 10) 5) '((0 5) (1 6) (2 7) (3 8) (4 9)))))

```
