Checkout the homepage, <https://scssphp.github.io/scssphp>, for directions on how to use. ## Running Tests `scssphp` uses [PHPUnit](https://github.com/sebastianbergmann/phpunit) for testing. Run the following command from the root directory to run every test: vendor/bin/phpunit tests There are several tests in the `tests/` directory: * `ApiTest.php` contains various unit tests that test the PHP interface. * `ExceptionTest.php` contains unit tests that test for exceptions thrown by the parser and compiler. * `FailingTest.php` contains tests reported in Github issues that demonstrate compatibility bugs. * `InputTest.php` compiles every `.scss` file in the `tests/inputs` directory then compares to the respective `.css` file in the `tests/outputs` directory. * `SassSpecTest.php` extracts tests from the `sass/sass-spec` repository. When changing any of the tests in `tests/inputs`, the tests will most likely fail because the output has changed. Once you verify that the output is correct you can run the following command to rebuild all the tests: BUILD=1 vendor/bin/phpunit tests This will compile all the tests, and save results into `tests/outputs`. It also updates the list of excluded specs from sass-spec. To enable the full `sass-spec` compatibility tests: TEST_SASS_SPEC=1 vendor/bin/phpunit tests ## Coding Standard `scssphp` source conforms to [PSR12](https://www.php-fig.org/psr/psr-12/). Run the following command from the root directory to check the code for "sniffs". vendor/bin/phpcs --standard=PSR12 --extensions=php bin src tests *.php scssphp/src/Node/Number.php 0000644 00000045024 15231105340 0011643 0 ustar 00 <?php /** * SCSSPHP * * @copyright 2012-2020 Leaf Corcoran * * @license http://opensource.org/licenses/MIT MIT * * @link http://scssphp.github.io/scssphp */ namespace ScssPhp\ScssPhp\Node; use ScssPhp\ScssPhp\Compiler; use ScssPhp\ScssPhp\Exception\SassScriptException; use ScssPhp\ScssPhp\Node; use ScssPhp\ScssPhp\Type; /** * Dimension + optional units * * {@internal * This is a work-in-progress. * * The \ArrayAccess interface is temporary until the migration is complete. * }} * * @author Anthon Pang <anthon.pang@gmail.com> */ class Number extends Node implements \ArrayAccess { const PRECISION = 10; /** * @var integer * @deprecated use {Number::PRECISION} instead to read the precision.

The CSS tree is fed into a * formatter, like `Formatter` which then outputs CSS as a string. * * During the first compile, all values are *reduced*, which means that their * types are brought to the lowest form before being dump as strings. This * handles math equations, variable dereferences, and the like. * * The `compile` function of `Compiler` is the entry point. * * In summary: * * The `Compiler` class creates an instance of the parser, feeds it SCSS code, * then transforms the resulting tree to a CSS tree. This class also holds the * evaluation context, such as all available mixins and variables at any given * time. * * The `Parser` class is only concerned with parsing its input. * * The `Formatter` takes a CSS tree, and dumps it to a formatted string, * handling things like indentation. */ /** * SCSS compiler * * @author Leaf Corcoran <leafot@gmail.com> */ class Compiler { /** * @deprecated */ const LINE_COMMENTS = 1; /** * @deprecated */ const DEBUG_INFO = 2; /** * @deprecated */ const WITH_RULE = 1; /** * @deprecated */ const WITH_MEDIA = 2; /** * @deprecated */ const WITH_SUPPORTS = 4; /** * @deprecated */ const WITH_ALL = 7; const SOURCE_MAP_NONE = 0; const SOURCE_MAP_INLINE = 1; const SOURCE_MAP_FILE = 2; /** * @var array<string, string> */ protected static $operatorNames = [ '+' => 'add', '-' => 'sub', '*' => 'mul', '/' => 'div', '%' => 'mod', '==' => 'eq', '!=' => 'neq', '<' => 'lt', '>' => 'gt', '<=' => 'lte', '>=' => 'gte', ]; /** * @var array<string, string> */ protected static $namespaces = [ 'special' => '%', 'mixin' => '@', 'function' => '^', ]; public static $true = [Type::T_KEYWORD, 'true']; public static $false = [Type::T_KEYWORD, 'false']; /** @deprecated */ public static $NaN = [Type::T_KEYWORD, 'NaN']; /** @deprecated */ public static $Infinity = [Type::T_KEYWORD, 'Infinity']; public static $null = [Type::T_NULL]; public static $nullString = [Type::T_STRING, '', []]; public static $defaultValue = [Type::T_KEYWORD, '']; public static $selfSelector = [Type::T_SELF]; public static $emptyList = [Type::T_LIST, '', []]; public static $emptyMap = [Type::T_MAP, [], []]; public static $emptyString = [Type::T_STRING, '"', []]; public static $with = [Type::T_KEYWORD, 'with']; public static $without = [Type::T_KEYWORD, 'without']; /** * @var array<int, string|callable> */ protected $importPaths = []; /** * @var array<string, Block> */ protected $importCache = []; /** * @var string[] */ protected $importedFiles = []; protected $userFunctions = []; protected $registeredVars = []; /** * @var array<string, bool> */ protected $registeredFeatures = [ 'extend-selector-pseudoclass' => false, 'at-error' => true, 'units-level-3' => true, 'global-variable-shadowing' => false, ]; /** * @var string|null */ protected $encoding = null; /** * @deprecated */ protected $lineNumberStyle = null; /** * @var int|SourceMapGenerator * @phpstan-var self::SOURCE_MAP_*|SourceMapGenerator */ protected $sourceMap = self::SOURCE_MAP_NONE; protected $sourceMapOptions = []; /** * @var string|\ScssPhp\ScssPhp\Formatter */ protected $formatter = Expanded::class; /** * @var Environment */ protected $rootEnv; /** * @var OutputBlock|null */ protected $rootBlock; /** * @var \ScssPhp\ScssPhp\Compiler\Environment */ protected $env; /** * @var OutputBlock|null */ protected $scope; /** * @var Environment|null */ protected $storeEnv; /** * @var bool|null */ protected $charsetSeen; /** * @var array<int, string> */ protected $sourceNames; /** * @var Cache|null */ protected $cache; /** * @var int */ protected $indentLevel; /** * @var array[] */ protected $extends; /** * @var array<string, int[]> */ protected $extendsMap; /** * @var array<string, int> */ protected $parsedFiles; /** * @var Parser|null */ protected $parser; /** * @var int|null */ protected $sourceIndex; /** * @var int|null */ protected $sourceLine; /** * @var int|null */ protected $sourceColumn; /** * @var resource */ protected $stderr; /** * @var bool|null */ protected $shouldEvaluate; /** * @var null * @deprecated */ protected $ignoreErrors; /** * @var bool */ protected $ignoreCallStackMessage = false; /** * @var array[] */ protected $callStack = []; /** * The directory of the currently processed file * * @var string|null */ private $currentDirectory; /** * The directory of the input file * * @var string */ private $rootDirectory; private $legacyCwdImportPath = true; /** * Constructor * * @param array|null $cacheOptions */ public function __construct($cacheOptions = null) { $this->parsedFiles = []; $this->sourceNames = []; if ($cacheOptions) { $this->cache = new Cache($cacheOptions); } $this->stderr = fopen('php://stderr', 'w'); } /** * Get compiler options * * @return array<string, mixed> */ public function getCompileOptions() { $options = [ 'importPaths' => $this->importPaths, 'registeredVars' => $this->registeredVars, 'registeredFeatures' => $this->registeredFeatures, 'encoding' => $this->encoding, 'sourceMap' => serialize($this->sourceMap), 'sourceMapOptions' => $this->sourceMapOptions, 'formatter' => $this->formatter, 'legacyImportPath' => $this->legacyCwdImportPath, ]; return $options; } /** * Set an alternative error output stream, for testing purpose only * * @param resource $handle * * @return void */ public function setErrorOuput($handle) { $this->stderr = $handle; } /** * Compile scss * * @api * * @param string $code * @param string $path * * @return string */ public function compile($code, $path = null) { if ($this->cache) { $cacheKey = ($path ? $path : '(stdin)') .
