split task pipelines for [Start](https://github.com/start-runner/start)

Apply a different set of tasks to each directory. Partially to overcome
[`start-write`](https://github.com/start-runner/write) stripping the root
directory for cases when relative directory structure must be retained (simple typescript + mocha).

## Install

```sh
npm install --save-dev start-split
# or
yarn add --dev start-split
```

## Usage

```js
import Start from 'start';
import reporter from 'start-pretty-reporter';
import files from 'start-files';
import read from 'start-read';
import write from 'start-write';
import split from 'start-split';

const start = Start(reporter());

export const task = () => start(
  files([ 'lib/**/*.js', 'test/**/*.js' ]),
  read(),
  split({
    lib: () => [ write('build/') ],
    test: () => [ write('testBuild/') ]
  })
);
```

This task relies on `[{ path, data, map }]` input and provides the same, see [documentation](https://github.com/start-runner/start#readme) for details.

## Arguments

`split(map, concurrent)`

*   `map` – A map of directory name to a function that returns an array of start tasks.
*   `concurrent` – Run task pipelines simultaneously using [`start-concurrent`][start-concurrent].
    Defaults to `true`.
