# babel-plugin-function-composition

This plugin is made to work with point-free (tacit) functional programming by composing functions

over piping. It is inspired by the work of [babel-plugin-pipe-operator-curry](https://github.com/Swizz/babel-plugin-pipe-operator-curry),

but with a very different purpose, with focus on omitting arguments. I've overloaded the operator `&` for that. You

can built more complex functions from simple ones.

## Examples

```javascript

import { add, multiply } from 'ramda';

const add5AndMul5 = add(5) & multiply(5);

```

Turn into

```javascript

import { add, multiply } from 'ramda';

const add5AndMul5 = (...args) => multiply(5)(add(5)(...args));

```

## Disabling in current scope

If you want to use the original bitwise and operator, you can disable this plugin in

current scope (and it children scopes) using `'no composition'` directive.

## Installation

```sh

$ npm install --save-dev babel-plugin-function-composition

```

## Usage

### Via `.babelrc` (Recommended)

**.babelrc**

```json

{

  "plugins": ["function-composition"]

}

```

### Via CLI

```sh

$ babel --plugins function-composition script.js

```

### Via Node API

```javascript

require('babel-core').transform('code', {

  plugins: ['function-composition']

});

```
