Peridocs

Peridocs is a Peridot plugin that generates automated markdown documentation from your peridot tests. I've found that my peridot tests are usually the best source of documentation. This project allows you to utilize your test documentation in an automated way.

Installation

Load with composer as a dev dependency: krak/peridocs.

In your peridot.php configuration file, add the following:

<?php

use Krak\Peridocs;

return function($emitter) {
    // the second parameter is optional and is used to configure the DocsContext
    Peridocs\bootstrap($emitter, function() {
        return new DocsContext(null, [
            'headerFmt' => '<h3 id="{id}">{signature}</h3>',
            'showLinks' => false,
            'nsPrefix' => 'Acme\\Prefix\\',
            'numTableRows' => 4,
        ]);
    });
};

Usage

Once registered, you can utilize the docFn function in your tests to enable documentation for the given test.

// function to test
function addMaybe(int $a, int $b): int {
    return $a == $b ? $a * $a : $a + $b;
}

// in some spec.php file
describe('Demo Package', function() {
    describe('addMaybe', function() {
        docFn(addMaybe::class); // this is the fully qualified name for the function e.g. 'Acme\Prefix\addMaybe'
        docIntro('`addMaybe` optional foreword/introduction.');

        it('usually adds two numbers together', function() {
            expect(addMaybe(1, 2))->equal(3);
        });
        it('but will multiply the two numbers when they are equal', function() {
            expect(addMaybe(3, 3))->equal(9);
        });

        docOutro('This is the optional outro/conclusion to be appended to the text');
    });
});

Now, you can generate the markdown by running peridot with the peridocs reporter.

./vendor/bin/peridot -r peridocs

It should output the following markdown:

<h3 id="api-krak-peridocs-addmaybe">addMaybe(int $a, int $b): int</h3>

**Name:** Krak\Peridocs\addMaybe

`addMaybe` optional foreword/introduction.

usually adds two numbers together:

```php
expect(addMaybe(1, 2))->equal(3);
```

but will multiply the two numbers when they are equal:

```php
expect(addMaybe(3, 3))->equal(9);
```

This is the optional outro/conclusion to be appended to the text
