Download the PHP package minime/annotations without Composer

Minime \ Annotations

Minime\Annotations is the first KISS PHP annotations library.

Composer Installation

Through terminal: composer require minime/annotations:~3.0 :8ball:

Setup

First grab an instance of the Minime\Annotations\Reader the lazy way:

Or instantiate the annotations reader yourself with:

Notice that Reader::createFromDefaults() creates a reader instance with array cache enabled. On production you might want to use a persistent cache handler like FileCache instead:

Reading Annotations

Consider the following class with some docblock annotations:

Let's use the Minime\Annotations\Reader instance to read annotations from classes, properties and methods. Like so:

The same applies to class properties...

methods...

and functions || closures:

Managing Annotations

The annotations reader Reader::get(*)Annotations always returns AnnotationsBag instances so you can easily manage annotations:

Namespacing

It's a good idea to namespace custom annotations that belong to a package. Later you can retrieve all those namespaced annotations using the AnnotationsBag api:

Piping Filters

You can also easily "pipe" filters. This time let's "grep" all annotations beginning with "x" and within "response" namespace:

Traversing results

As you might expect, AnnotationsBag is traversable too:

Union

You can also perform union operations between two annotations sets:

Please refer to annotations bag public API for more operations.

The Default Syntax

Which basically means that:

• @ line must start with a docblock annotation tag
• must have an annotation identifier
  • annotation identifier can have namespace with segments delimited by . or \
• whitespace
• can have an annotation value
  • value can have an optional type [json, string, integer, float, ->]
    • if absent, type is assumed from value
  • whitespace
  • optional value
    • if absent, true is assumed

Some valid examples below:

Concrete Annotations

Sometimes you need your annotations to encapsulate logic and you can only do it by mapping instructions to formal PHP classes. These kind of "concrete" typed annotations can be declared with the -> (arrow symbol):

In the example above: when prompted, the annotation parser will instantiate a new \Model\Field\Validation() following the declared JSON prototype { "rules" : {...} }. Voilà! Instantly classy annotations.

Caching

This package comes with two basic cache handlers. ArrayCache (for testing) and a very simple FileCache handler for persistence. Cache handlers can be set during Minime\Annotations\Reader instantiation:

Or later with Reader::setCache():

Public API

Minime\Annotations\Reader

::getClassAnnotations($subject)

Get all annotations from a given class:

::getPropertyAnnotations($subject, $propertyName)

Get all annotations from a given class property:

::getMethodAnnotations($subject, $methodName)

Get all annotations from a given class method:

::getFunctionAnnotations($fn)

Get all annotations from a given full qualified function name or closure:

::getCache()

::setCache(CacheInterface $cache)

::getParser()

::setParser(ParserInterface $cache)

Minime\Annotations\AnnotationsBag

::grep($pattern)

Filters annotations using a valid regular expression and returns a new AnnotationBag with the matching results.

::useNamespace($pattern)

Isolates a given namespace of annotations. Basically this method filters annotations by a namespace and returns a new AnnotationBag with simplified annotations identifiers.

::union(AnnotationsBag $bag)

Performs union operation with a subject AnnotationBag:

::toArray()

::get($key, $default = null)

::getAsArray($key)

::has($key)

::set($key, $value)

::count

Minime\Annotations\Cache\FileCache

::__construct($storagePath = null)

See example in context with Minime\Annotations\Reader:

If no path is given OS tmp dir is assumed as cache storage path.

::clear()

Clears entire cache. See example in context with Minime\Annotations\Reader:

Minime\Annotations\Cache\ArrayCache

::clear()

Clears entire cache. See example in context with Minime\Annotations\Reader:
