MO4 Coding Standard
-------------------

[](#mo4-coding-standard)

The MO4 Coding Standard is an extension of the [Symfony Coding Standard](http://symfony.com/doc/current/contributing/code/standards.html) and adds following rules:

### MO4.Arrays.ArrayDoubleArrowAlignment

[](#mo4arraysarraydoublearrowalignment)

- In associative arrays, the `=>` operators must be aligned.
- In arrays, the key and `=>` operator must be on the same line.

### MO4.Arrays.MultiLineArray

[](#mo4arraysmultilinearray)

- In multi line arrays, the opening bracket must be followed by newline.
- In multi line arrays, the closing bracket must be in own line.
- In multi line arrays, the elements must be indented.

### MO4.Commenting.PropertyComment

[](#mo4commentingpropertycomment)

- doc blocks of class properties must be multiline and have exactly one `@var` annotation

### MO4.Formatting.AlphabeticalUseStatements

[](#mo4formattingalphabeticalusestatements)

- `use` statements must be sorted lexicographically. The order function can be configured.

#### Configuration

[](#configuration)

The `order` property of the `MO4.Formatting.AlphabeticalUseStatements` sniff defines which function is used for ordering.

Possible values for order:

- `dictionary` (default): based on [strcmp](http://php.net/strcmp), the namespace separator precedes any other character ```
    use Doctrine\ORM\Query;
    use Doctrine\ORM\Query\Expr;
    use Doctrine\ORM\QueryBuilder;
    ```
- `string`: binary safe string comparison using [strcmp](http://php.net/strcmp)```
    use Doctrine\ORM\Query;
    use Doctrine\ORM\QueryBuilder;
    use Doctrine\ORM\Query\Expr;

    use ExampleSub;
    use Examples;
    ```
- `string-locale`: locale based string comparison using [strcoll](http://php.net/strcoll)
- `string-case-insensitive`: binary safe case-insensitive string comparison [strcasecmp](http://php.net/strcasecmp)```
    use Examples;
    use ExampleSub;
    ```

To change the sorting order for your project, add this snippet to your custom `ruleset.xml`:

```

```

### MO4.Formatting.UnnecessaryNamespaceUsage

[](#mo4formattingunnecessarynamespaceusage)

- The imported class name must be used, when it was imported with a `use` statement.

### MO4.Strings.VariableInDoubleQuotedString

[](#mo4stringsvariableindoublequotedstring)

- Interpolated variables in double quoted strings must be surrounded by `{ }`, e.g. `{$VAR}` instead of `$VAR`.

### MO4.WhiteSpace.ConstantSpacing

[](#mo4whitespaceconstantspacing)

- const must be followed by a single space.

### MO4.WhiteSpace.MultipleEmptyLines

[](#mo4whitespacemultipleemptylines)

- No more than one empty consecutive line is allowed. Taken from [mediawiki/mediawiki-codesniffer](https://github.com/wikimedia/mediawiki-tools-codesniffer).

### Further rules (imported from other standards)

[](#further-rules-imported-from-other-standards)

- See `MO4/ruleset.xml`, which has each imported rule commented.

Note that with this ruleset, the following [Symfony Coding Standard](http://symfony.com/doc/current/contributing/code/standards.html) rules are not enforced:

- "`add doc blocks for all classes`": the doc block for classes can be omitted, if they add no value
- "`the license block has to be present at the top of every PHP file, before the namespace`": the license block can be omitted

Most of the issues can be auto-fixed with `phpcbf`.

Requires
--------

[](#requires)

- [PHP](http://php.net)
- [Composer](https://getcomposer.org/) is optional, but strongly recommended

Installation
------------

[](#installation)

### Composer

[](#composer)

Using [Composer](https://getcomposer.org/) is the preferred way.

1. Add the MO4 coding standard to `composer.json`

    ```
     composer require --dev mayflower/mo4-coding-standard

    ```
2. Profit

    ```
     ./vendor/bin/phpcs --standard=MO4 path/to/my/file.php

    ```
3. Optionally, you might set MO4 as default coding standard

    ```
     ./vendor/bin/phpcs --config-set default_standard MO4

    ```

### Source

[](#source)

1. Checkout this repository

    ```
     git clone https://github.com/mayflower/mo4-coding-standard.git

    ```
2. Install dependencies

    ```
     composer install

    ```
3. Check, that Symfony and MO4 are listed as coding standards

    ```
     ./vendor/bin/phpcs -i

    ```
4. Profit

    ```
     ./vendor/bin/phpcs --standard=MO4 path/to/my/file.php

    ```
5. Optionally, you might set MO4 as default coding standard

    ```
     ./vendor/bin/phpcs --config-set default_standard MO4

    ```

Troubleshooting
---------------

[](#troubleshooting)

If `phpcs` complains that MO4 is not installed, please check the installed coding standards with `phpcs -i` and that `installed_paths` is set correctly with `phpcs --config-show`

Dependencies
------------
