*A counterfeit co refer to [co](https://github.com/tj/co/tree/master).*

Generator based flow-control goodness for nodejs, using thunks or promises, letting you write non-blocking code in a nice-ish way.

### Installation

`npm install @singcl/co -S`

### Example

```js

var fs = require('fs');

var path = require('path');

var co = require('@singcl/co');

var thunkify = co.thunkify;

var promisify = co.promisify;

var reaFileThunkify = thunkify(fs.readFile);

var reaFilePromisify = promisify(fs.readFile);

var filePath1 = path.resolve(__dirname, './test.txt');

var filePath2 = path.resolve(__dirname, './co.exam.js');

co(function* (path) {

    var a = yield reaFileThunkify(path, 'utf8');

    var b = yield reaFileThunkify(path, 'utf8');

    var c = yield reaFileThunkify(path, 'utf8');

    console.log(a);

    console.log(b);

    console.log(c);

}, filePath1).then(function(v) {

    console.log('co完成！', v);

});

co(function* (path) {

    var a = reaFilePromisify(path, 'utf8');

    var b = reaFilePromisify(path, 'utf8');

    var c = reaFilePromisify(path, 'utf8');

    var res = yield [a, b, c];

    console.log(res);

}, filePath2).then(function(v) {

    console.log('co完成！', v);

});

```

### Yieldables

The "yieldable" objects currently supported are:

- promises

- thunks (functions)

- array (parallel execution)

- generators (delegation)

- generator functions (delegation)
