FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Installation
Recommended installation is through Composer.
Usage
Assumption is that there exists a valid enum \YesNoEnum.
Form
Form type for enum is provided as \Zlikavac32\SymfonyEnum\Form\Type\EnumType. There is one required options enum_class which must contain enum class FQN.
Internally this extends \Symfony\Component\Form\Extension\Core\Type\ChoiceType and populates choices from the defining enum_class.
If any of the choices and/or choice_loader options is/are passed, an \LogicException will be thrown. Since these fields are overridden internally, passing them from the outside could cloud code's original purpose. Any other option provided by the \Symfony\Component\Form\Extension\Core\Type\ChoiceType can be used.
Validator
Two constraints are provided, \Zlikavac32\SymfonyEnum\Validator\Constraints\ValidEnumElement and \Zlikavac32\SymfonyEnum\Validator\Constraints\ValidEnumElementName. Internally, they use \Symfony\Component\Validator\Constraints\Choice.
Required constraint argument is enumClass which must contain enum class FQN.
If any of the choices, callback and/or strict options is/are passed, an \LogicException will be thrown. Since these fields are overridden internally, passing them from the outside could cloud code's original purpose. Any other option provided by the \Symfony\Component\Validator\Constraints\Choice can be used.

Limitations
Due to doctrine/common issue #794 with checks for aliased namespaces, validation of form enum element within an array will throw exception in following cases:
- on
Windowsvalidation does not work at all (due to the anonymous classes) - on
Linux- short enum definition (one that useseval()) does not work so the workaround is to manually instantiate elements - on
OSX- have to check but I'd assume same asLinux
