README

Ukon is a unit conversion calculator library. You can make your own unit conversion settings easily with it.

Installation

composer require burobo/ukon

Usage

1. Create your own Unit class.

   use Ukon\Unit;
   
   class Metre extends Unit
   {
       /**
        * @inheritDoc
        */
       protected function languageSpecificFormats(): array
       {
           return [
               'default' => '%s metre',
           ];
       }
   
       /**
        * @inheritDoc
        */
       protected function globalFormats(): array
       {
           return [
               'abbr' => '%sm',
           ];
       }
   
       /**
        * @inheritDoc
        */
       protected function domain(): string
       {
           return 'messages';
       }
   }

2. Create your own Type class.

   use Ukon\Type;
   
   class Length extends Type
   {
       /**
        * @inheritDoc�
        */
       public function __construct(int $scale)
       {
           parent::__construct($scale);
           $this->registerUnitRatio(Metre::class, 1000);
           $this->registerUnitRatio(Centimetre::class, 10);
           $this->registerUnitRatio(Millimetre::class, 1);
       }
   }

3. Now you can convert and calculate your own unit!

   $height = (new Length(1))
       ->addMetre(1.7)
       ->addMillimetre(1);
   
   $height->stringify(function (Metre $metre, Centimetre $centimetre, Millimetre $millimetre) {
       return $metre->fmtAbbr() . ' ' . $centimetre->fmtAbbr() . ' ' . $millimetre->fmtAbbr();
   }); // 1m 70cm 1mm
