metarush/getter

Generate a class with getter methods from a yaml or env file. This is useful if you want to access variables in yaml/env files as PHP getter methods.

Install

Install via composer as metarush/getter

Sample usage

The following will generate a class named MyNewClass from contents of foo/sample.yaml using yaml adapter. The generated class will be saved in foo/ folder.

via CLI

vendor/metarush/getter/bin/generate -a yaml -c MyNewClass -s tests/unit/samples/sample.yaml -l foo/

via PHP script

(new \MetaRush\Getter\Generator)
    ->setAdapter('yaml')
    ->setClassName('MyNewClass')
    ->setSourceFile('foo/sample.yaml')
    ->setLocation('foo/')
    ->generate();

Sample yaml content

E.g., located in foo/sample.yaml

stringVar: 'foo'
intVar: 9
floatVar: 2.1
boolVar: true
arrayVar:
  - foo
  - 1.3

Sample generated class

E.g., located in foo/MyNewClass.php

<?php

declare(strict_types=1);

namespace MyNamespace;

class MyNewClass
{
    private $stringVar = 'foo';
    private $intVar = 9;
    private $floatVar = 2.1;
    private $boolVar = true;
    private $arrayVar = [0 => 'foo', 1 => 1.3];

    public function getStringVar(): string
    {
        return $this->stringVar;
    }

    public function getIntVar(): int
    {
        return $this->intVar;
    }

    public function getFloatVar(): float
    {
        return $this->floatVar;
    }

    public function getBoolVar(): bool
    {
        return $this->boolVar;
    }

    public function getArrayVar(): array
    {
        return $this->arrayVar;
    }
}

Supported types

• string
• int
• float
• bool
• array (only available in yaml adapter)

Adapters

• yaml
• env

Advanced usage

Include namespace

If you want to include a namespace, use ->setNamespace('MyNamespace') or via CLI --namespace MyNamespace

Extend class

If you want to extend a class, use ->setExtendedClass('MyBaseClass') or via CLI --extendClass MyBaseClass

Dummify field values

If you want to dummify field values, use the ->setDummifyValues(true) config method or via CLI --dummify

Why dummify?

It's useful for hiding sensitive data such as credentials. Credentials should not be in the source code. The field values of the generated classes with dummy data can later be repopulated (by your custom scripts) on runtime with actual values (see data replacer below). The generated class retains the data types even if the original values have been dummified.

If dummified, the generated field values are as follows:

[
    'x', // string
    1, // int
    1.2, // float
    true, // true
    [0 => 'x'] // array
];

Data replacer for dummified values

If you want to dynamically change the values of the dummified data on runtime, use ->setConstructorType(\MetaRush\Getter\Config::CONSTRUCTOR_DATA_REPLACER); or via CLI --dataReplacer

You can then call the generated class and inject an array of replacement values on runtime:

// $replacementValues should contain key value pair that matches the dummified data

$newClass = new MyNewClass($replacementValues);

Call parent

If you want to call a parent class, use ->setConstructorType(\MetaRush\Getter\Config::CONSTRUCTOR_CALL_PARENT) or via CLI --callParent

Call parent and use data replacer

If you want to call a parent class and also use data replacer, use ->setConstructorType(\MetaRush\Getter\Config::CONSTRUCTOR_BOTH) or via CLI --callParent --dataReplacer

Note: You should only call ->setConstructorType() once

Generate constants

If you want to generate the key/value pairs as constants, use ->setGenerateAsConstants(true) or via CLI --constants.
