After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

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 PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • 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.

Informations about the package colorhelper

PackageFactory.ColorHelper

The package provides the Fusion Prototype Vendor.Site:CustomCssProperties for rendering css custom-properties together with an EEL Color Helper that provides an interface for fluent color transformations.

Rendering as Css Custom Properties

The fusion prototype PackageFactory.ColorHelper:CssVariables allows to render DataStructures as CssVariables. This can be used for customizing css based on node properties as shown in the example below.

PackageFactory.ColorHelper:CssVariables

Handling colors with EEL

Creating

Colors can be created from hex, rgb and hsl values

The methods rgb and hsl allow to specify the alpha as fourth argument expecting a float between 0 and 1 color = ${ Color.hsl(156, 25, 75, 0.5) }

If you have a color value specified as css color string you can use the Color.css method to instantiate the color. Plaese be aware that this uses a very simple regex based parser for the css colors and for now only suppprts hex,rgb and hsla colors.

Manipulating

Once created those colors can then be manipulated via fluent interface like a flow query for colors.

Adjust saturation

Adjust lightness

Modify the color value by rotating in the hue axis

Invert color

Fade colors

Mix colors

Offcourse this can be used in afx attributes as any other eel expression.

Value rendering

When casted to string the color objects will render as hex value. For special requirements the format can be specified. All formats will only render an alpha value if the color is transparent.

Installation

PackageFactory.ColorHelper is available via packagist. Run composer require packagefactory/colorhelper. We use semantic-versioning so every breaking change will increase the major-version number.
