About
-----

[](#about)

`codamos/tagger` is a simple tagging library inspired by Go's [struct tags](https://go.dev/ref/spec#Struct_types). It allows you to fetch free-form tags from class properties via a `Tag` attribute that can later be used by third-party libraries or your own code.

The library also includes a tag parser and a class tags scanner. These should allow you to use tagger at scale for your entire application at build time, or at runtime.

Installation
------------

[](#installation)

Install this package as a dependency using [Composer](https://getcomposer.org).

```
composer require codamos/tagger
```

Usage
-----

[](#usage)

You may use the `Tag` attribute to annotate your class' properties with free-form tags, split by space characters.

```
use Codamos\Tagger\Attributes\Tag;
use Codamos\Tagger\Parser\TagParser;
use Codamos\Tagger\Scanner\TagScanner;

class UserDTO
{
    #[Tag('json:"id" orm:"id,primaryKey,autoIncrement"')]}
    public int $id;

    #[Tag('json:"name" orm:"name,notNull,size:255"')]
    public string $name;

    #[Tag('json:"email" orm:"email,notNull,size:255,unique,index"')]
    public string $email;

$parser = new TagParser();
$scanner = new TagScanner($scanner);

$map = $scanner->scan(UserDTO::class);

$emailTags = $map->get('email');
$emailTags->get('json'); // string(json:"email")
$emailTags->get('orm'); // string(orm:"email,notNull,size:255,unique,index")
```
