CrescendoVarBundle

Elevate Your Code to a Symphony of Efficiency with CrescendoVarBundle: Where Every Variable Plays its Part Perfectly.

Overview

The phillarmonic/crescendo-var-bundle is a Symfony Bundle designed to enhance your development workflow by simplifying environment variable manipulation. With its intuitive features, developers can effortlessly convert environment variable strings into integers or booleans, as well as transform a single environment variable into an array.

This document provides a comprehensive guide on how to integrate and utilize the CrescendoVarBundle in your projects.

This is particularly useful when you need values of a specific type, but your workflow necessitates the use of strings to set your environment variables. An example of this is an ArgoCD YAML file, which requires all values to be strings.

Features

• Automatic Type Conversion: Easily convert string environment variables to integers (int) or booleans (bool) to ensure the correct data types are used in your application.
• Array Transformation: Split a single environment variable into an array, allowing for more complex configurations that can be dynamically adjusted via environment variables.
• Edge Case Handling: Specifically designed to manage edge cases in environment variable processing, ensuring robust and error-free application configuration.

Installation

To install the CrescendoVarBundle, run the following command in your project directory:

Ensure that your project's composer.json is updated and that the package is installed successfully.

Configuration

After installation, configure the bundle by adding it to your application's bundle configuration. This process may vary depending on the framework or platform you are using. Typically, it involves registering the bundle in a configuration file or through an application's bundle registration system.

Usage

CrescendoVarBundle simplifies the usage of environment variables by providing special processors to handle common use cases. Below are examples of how to use these processors in your application:

Converting String to Integer

Use the tryint processor to convert an environment variable value to an integer. This is particularly useful for ports and other numerical configurations.

Converting String to Boolean

The trybool processor converts an environment variable value to a boolean. This is ideal for feature flags and other boolean-based configurations.

Explode Environment Variable into an Array

The explode processor splits a single environment variable into an array based on a delimiter (default is coma ,). This is useful for lists of hosts, tags, or any multivalued configuration.
