Slevomat Coding Standard for [PHP_CodeSniffer](https://github.com/PHPCSStandards/PHP_CodeSniffer) provides sniffs that fall into three categories:
* Functional - improving the safety and behaviour of code
* Cleaning - detecting dead code
* Formatting - rules for consistent code looks

## Installation
The recommended way to install Slevomat Coding Standard is [through Composer](http://getcomposer.org).
```JSON
{
"require-dev": {
"slevomat/coding-standard": "~8.0"
}
}
```
It's also recommended to install [php-parallel-lint/php-parallel-lint](https://github.com/php-parallel-lint/PHP-Parallel-Lint) which checks source code for syntax errors. Sniffs count on the processed code to be syntactically valid (no parse errors), otherwise they can behave unexpectedly. It is advised to run `PHP-Parallel-Lint` in your build tool before running `PHP_CodeSniffer` and exiting the build process early if `PHP-Parallel-Lint` fails.
## How to run the sniffs
You can choose one of two ways to run only selected sniffs from the standard on your codebase:
### Choose which sniffs to run
The recommended way is to write your own ruleset.xml by referencing only the selected sniffs. This is a sample ruleset.xml:
```xml
```
Then run the `phpcs` executable the usual way:
```
vendor/bin/phpcs --standard=ruleset.xml --extensions=php --tab-width=4 -sp src tests
```
### Exclude sniffs you don't want to run
You can also mention Slevomat Coding Standard in your project's `ruleset.xml` and exclude only some sniffs:
```xml
```
However it is not a recommended way to use Slevomat Coding Standard, because your build can break when moving between minor versions of the standard (which can happen if you use `^` or `~` version constraint in `composer.json`). We regularly add new sniffs even in minor versions meaning your code won't most likely comply with new minor versions of the package.
## Fixing errors automatically
Sniffs in this standard marked by the 🔧 symbol support [automatic fixing of coding standard violations](https://github.com/PHPCSStandards/PHP_CodeSniffer/wiki/Fixing-Errors-Automatically). To fix your code automatically, run phpcbf instead of phpcs:
```
vendor/bin/phpcbf --standard=ruleset.xml --extensions=php --tab-width=4 -sp src tests
```
Always remember to back up your code before performing automatic fixes and check the results with your own eyes as the automatic fixer can sometimes produce unwanted results.
## Suppressing sniffs locally
Selected sniffs in this standard marked by the 🚧 symbol can be suppressed for a specific piece of code using an annotation. Consider the following example:
```php
/**
* @param int $max
*/
public function createProgressBar($max = 0): ProgressBar
{
}
```
The parameter `$max` could have a native `int` scalar typehint. But because the method in the parent class does not have this typehint, so this one cannot have it either. PHP_CodeSniffer shows a following error:
```
----------------------------------------------------------------------
FOUND 1 ERROR AFFECTING 1 LINE
----------------------------------------------------------------------
67 | ERROR | [x] Method ErrorsConsoleStyle::createProgressBar()
| | does not have native type hint for its parameter $max
| | but it should be possible to add it based on @param
| | annotation "int".
| | (SlevomatCodingStandard.TypeHints.ParameterTypeHint.MissingNativeTypeHint)
```
If we want to suppress this error instead of fixing it, we can take the error code (`SlevomatCodingStandard.TypeHints.ParameterTypeHint.MissingNativeTypeHint`) and use it with a `@phpcsSuppress` annotation like this:
```php
/**
* @phpcsSuppress SlevomatCodingStandard.TypeHints.ParameterTypeHint.MissingNativeTypeHint
* @param int $max
*/
public function createProgressBar($max = 0): ProgressBar
{
}
```
## Contributing
To make this repository work on your machine, clone it and run these two commands in the root directory of the repository:
```
composer install
bin/phing
```
After writing some code and editing or adding unit tests, run phing again to check that everything is OK:
```
bin/phing
```
We are always looking forward to your bugreports, feature requests and pull requests. Thank you.
