README

Latest Stable Version Total Downloads License

This package provides a Fusion object to simplify common string matching.

Inspired by the PHP 8 match expression.

The goal for this plugin is to provide the given functionality to Neos CMS >= 4.3 ⚠️ The features this package provides is included in Neos 7.3. Therefore this package will not be developed further.

Installation

Run the following command in your site package:

composer require --no-update shel/fusion-match

Then run composer update in your project root.

Examples

Basic

The following Fusion code is very verbose and has repetitions:

rowClass = Neos.Fusion:Case {
    case1 {
      condition = ${q(node).property('columns') == "one"}
      renderer = "d-flex col-12 col-md-6 col-lg-12"
    }
    case2 {
      condition = ${q(node).property('columns') == "two"}
      renderer = "d-flex col-12 col-md-6 col-lg-6"
    }
    case3 {
      condition = ${q(node).property('columns') == "three"}
      renderer = "d-flex col-12 col-md-6 col-lg-4"
    }
    case4 {
      condition = ${q(node).property('columns') == "four"}
      renderer = "d-flex col-12 col-md-6 col-lg-3"
    }
}

With the Match object this becomes compact and readable:

rowClass = Shel.Fusion:Match {
    @subject = ${q(node).property('columns')}
    one = 'd-flex col-12 col-md-6 col-lg-12'
    two = 'd-flex col-12 col-md-6 col-lg-6'
    three = 'd-flex col-12 col-md-6 col-lg-4'
    four = 'd-flex col-12 col-md-6 col-lg-3'
}

Providing a default

You can also provide a default via @default:

rowClass = Shel.Fusion:Match {
    @subject = ${q(node).property('layout')}
    @default = ''
    left = 'my-module--left'
    right = 'my-module--right'
}

Matches with same values

Sometimes you have a Fusion case that would match to several strings with the same return value. You can solve this more explicit like this:

myVar = Shel.Fusion:Match {
    @subject = ${q(node).property('layout')}
    left = 'my-module--left'
    right = 'my-module--right' 
    top = ${this.left} 
    bottom = ${this.left} 
}

Other return types

myVar = Shel.Fusion:Match {
    @subject = ${q(node).property('someProperty')}
    @default = ''
    case1 = afx`
        <div>hello world</div>     
    `
    case2 = 2
    case3 = Neos.Fusion:Value {
        value = 'hello world'
    }           
    case4 = Neos.Fusion:DataStructure {
        my = 'array'
    } 
}

Make sure all cases return the same type, or you will get into trouble 😉

Usage in AFX

myVar = 'test' 
renderer = afx`
    <div>
        <Shel.Fusion:Match @subject={props.myVar}>
            <span @path="test">Hello world</span>
            <span @path="@default">No match found</span>
        </Shel.Fusion:Match>
    </div>
`    

Type checking and error handling

The object expects to find a match. Either one of the provided cases or the default. If no case matches and no default has been provided an exception will be raised.

The subject will be casted to a string. If a subject is provided that cannot be casted to a string it will also cause an error.

The matchable cases also will be cast to a string. So you can use strings or numbers.
