This also adds Python-2.0 to the list of accepted licenses. Lastly, it fixes a bug where the package.json files were incorrectly reordered. For the `exports` of a particular package, the order that the entrypoints are defined in is crucial. Therefore, we should not alter the order of entrypoints and instead maintain the originally defined ordering. We can use an `OrderedDict` to ensure that Python always loads the JSON files in the same order.

pify 
Promisify a callback-style function
Install
$ npm install --save pify
Usage
const fs = require('fs');
const pify = require('pify');
// promisify a single function
pify(fs.readFile)('package.json', 'utf8').then(data => {
console.log(JSON.parse(data).name);
//=> 'pify'
});
// or promisify all methods in a module
pify(fs).readFile('package.json', 'utf8').then(data => {
console.log(JSON.parse(data).name);
//=> 'pify'
});
API
pify(input, [promiseModule], [options])
Returns a promise wrapped version of the supplied function or module.
input
Type: function, object
Callback-style function or module whose methods you want to promisify.
promiseModule
Type: function
Custom promise module to use instead of the native one.
Check out pinkie-promise if you need a tiny promise polyfill.
options
multiArgs
Type: boolean
Default: false
By default, the promisified function will only return the second argument from the callback, which works fine for most APIs. This option can be useful for modules like request that return multiple arguments. Turning this on will make it return an array of all arguments from the callback, excluding the error argument, instead of just the second argument.
const request = require('request');
const pify = require('pify');
pify(request, {multiArgs: true})('https://sindresorhus.com').then(result => {
const [httpResponse, body] = result;
});
include
Type: array of (string|regex)
Methods in a module to promisify. Remaining methods will be left untouched.
exclude
Type: array of (string|regex)
Default: [/.+Sync$/]
Methods in a module not to promisify. Methods with names ending with 'Sync' are excluded by default.
excludeMain
Type: boolean
Default: false
By default, if given module is a function itself, this function will be promisified. Turn this option on if you want to promisify only methods of the module.
const pify = require('pify');
function fn() {
return true;
}
fn.method = (data, callback) => {
setImmediate(() => {
callback(data, null);
});
};
// promisify methods but not fn()
const promiseFn = pify(fn, {excludeMain: true});
if (promiseFn()) {
promiseFn.method('hi').then(data => {
console.log(data);
});
}
