SemVer Converter
================

[](#semver-converter)

Converts SemVer version (like Composer packages) into integer version with operators. Helps managing versions: store, compare, sort and retrive by conditions.

Converter accepts the same versions as Composer, so You can use it with any package manager that accepts [Semantic Versioning](http://semver.org/).

How it works?
=============

[](#how-it-works)

For each version it uses Composer SemVer parser to parse version and normalize it. And then, for each version, converter creates array exploded by dot values. Each value pads with zeros and create from it long string which is converted to integer. And for each version we have big integer.

### Sample:

[](#sample)

1. Version **1.0.5**
2. Normalize with SemVer: **1.0.5**
3. Explode: **\[ 1, 0, 5 \]**
4. Converts to strings and pad zeros: **\[ '001', '000', '005' \]**
5. Concatenate all strings: **'001' + '000' + '005'**
6. Converts to integer: **(int) '1000005'**

Result: **'1.0.5' == 1000005**

Examples
========

[](#examples)

### Simple version

[](#simple-version)

```
$result = (new SemVerConverter)->convert('0.1.0');

// Result
array (size=1)
  0 =>
    array (size=2)
      'from' =>
        array (size=2)
          0 => int 1000000
          1 => string '==' (length=2)
      'to' =>
        array (size=2)
          0 => int 1000000
          1 => string '==' (length=2)
```

### Version between

[](#version-between)

```
$result = (new SemVerConverter)->convert('>= 1.3.0 < 1.7.0');

// Result
array (size=1)
  0 =>
    array (size=2)
      'from' =>
        array (size=2)
          0 => int 1003000
          1 => string '>=' (length=2)
      'to' =>
        array (size=2)
          0 => int 1007000
          1 => string '=' (length=2)
      'to' =>
        array (size=2)
          0 => int 2000000
          1 => string '=' (length=2)
      'to' =>
        array (size=2)
          0 => int 2000000
          1 => string '=' (length=2)
      'to' =>
        array (size=2)
          0 => int 3001000
          1 => string '
