`scssphp` is a compiler for SCSS written in PHP.

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.
* `ScssTest.php` extracts (ruby) `scss` tests from the `tests/scss_test.rb` file.

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`.

To enable the `scss` compatibility tests:

    TEST_SCSS_COMPAT=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
