[SlevomatCodingStandard.Whitespaces.DuplicateSpaces](doc/whitespaces.md#slevomatcodingstandardwhitespacesduplicatespaces-) 🔧 Installation ------------ [](#installation) The recommended way to install Slevomat Coding Standard is [through Composer](http://getcomposer.org). ``` { "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 --------------------- [](#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 [](#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: ``` ``` 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 [](#exclude-sniffs-you-dont-want-to-run) You can also mention Slevomat Coding Standard in your project's `ruleset.xml` and exclude only some sniffs: ``` ``` 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 --------------------------- [](#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 -------------------------- [](#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: ``` /** * @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: ``` /** * @phpcsSuppress SlevomatCodingStandard.TypeHints.ParameterTypeHint.MissingNativeTypeHint * @param int $max */ public function createProgressBar($max = 0): ProgressBar { } ``` Contributing ------------ [](#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.
