## Installation

```shell

npm install parse-gurobi-solution

```

## Usage

The method exposed by this module takes a single `fileStream` parameter, which is a stream of your `.sol` solution file and returns a [Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/promise) that will resolve in an object with your variable names as keys.

```javascript

const fs = require('fs')

const parseGurobiSolution = require('parse-gurobi-solution')

const fileStream = fs.createReadStream('./solution.sol')

const solution = parseGurobiSolution(fileStream).then(console.log) // Promise

```

The following solution file example:

```

# Objective value = 3.6700000000001825e+02

a0 1

a1 2.128473937036380e-7

b0 3.1268

b1 2

xcoord 10

ycoord 0

lat 2.91256

```

would give you a `solution` object that looks as follows:

```js

{

    a0: 1,

    a1: 2.12847393703638e-7,

    b0: 3.1268,

    b1: 2,

    xcoord: 10,

    ycoord: 0,

    lat: 2.91256

}

```
