UpToDocs

UpToDocs scans a Markdown file for PHP code blocks, and executes each one in a separate process.

Include this in your CI workflows, to make sure your documentation is always up to date with your code.

Usage

composer require --dev mathiasverraes/uptodocs

CLI:

vendor/bin/uptodocs run [options] [--] <markdownFile>

Arguments:
  markdownFile          Markdown file to run.

Options:
  -b, --before=BEFORE   A PHP file to run before each code block. 
                        Useful for imports and other setup code.
  -a, --after=AFTER     A PHP file to run after each code block. 
                        Useful for cleanup, and for running assertions.

In your code:

<?php
$upToDocs = new Verraes\UpToDocs\UpToDocs();
$result = $upToDocs->run("README.md"); // bool

Example

You can try it on the Markdown file in the sample directory:

./uptodocs run sample/docs.md --before sample/before.php

Output:

The following code block in /Users/mathias/workspace/php/uptodocs/sample/docs.md:16 failed.
<?php
$v = multiplyy(10,2);

PHP Fatal error:  Uncaught Error: Call to undefined function multiplyy() in Standard input code:11
Stack trace:

  thrown in Standard input code on line 11

UpToDocs discovered a typo in our sample code. Oops!
