exercism fetch php markdown


Refactor a Markdown parser.

The markdown exercise is a refactoring exercise. There is code that parses a given string with Markdown syntax and returns the associated HTML for that string. Even though this code is confusingly written and hard to follow, somehow it works and all the tests are passing! Your challenge is to re-write this code to make it easier to read and maintain while still making sure that all the tests keep passing.

It would be helpful if you made notes of what you did in your refactoring in comments so reviewers can see that, but it isn't strictly necessary. The most important thing is to make the code better!

Running the tests

  1. Go to the root of your PHP exercise directory, which is <EXERCISM_WORKSPACE>/php. To find the Exercism workspace run

    % exercism debug | grep Workspace
  2. Get PHPUnit if you don't have it already.

    % wget --no-check-certificate https://phar.phpunit.de/phpunit.phar
    % chmod +x phpunit.phar
  3. Execute the tests:

    % ./phpunit.phar markdown/markdown_test.php
