Download the PHP package jascha030/twig-service without Composer

Twig Service

Simple set of two interfaces and one basic implementation of a service class for usage with Twig.

Getting Started

Requirements

• PHP ^8
• Composer * (but preferred 2.2 or later)

Installation

Usage

The package contents consist of one simple service class implementing, an interface, which extends one extra interface that implements the features that are independent from twig/twig.

TwigServiceInterface

The main interface is the Jascha030\Twig\TwigServiceInterface, which requires a class to implement three methods.

Methods

getEnvironment

Get the TwigEnvironment.

TwigServiceInterface::getEnvironment(): \Twig\Environment

• returns \Twig\Environment instance.

Inherited methods

The methods below are inherited from Jascha030\Twig\Templater\TemplaterInterface.

This is done to open future possibility to replace your Twig-specific implementation with another templating method, without having to refactor your codebase, for example, by using a DIC.

For this reason, using container bindings bound to the TemplaterInterface instead of the TwigServiceInterface. For the same reason it is recommended to let other classes depend on the TemplaterInterface. For dependent classes, the fact that the service uses a Twig\Environment instance to render the output, should not be relevant.

renderString

Render a template and return output as string.

TemplaterInterface::renderString(string $template, array $context = []): string

• parameters
  • $template (string): the twig template name.
  • $context (array): key => pair values corresponding to the template variables.
• returns the rendered template as string

render

Render and output a template.

TemplaterInterface::render(string $template, array $context = []): void

• parameters
  • $template (string): the twig template name.
  • $context (array): key => pair values corresponding to the template variables.
• returns void (output is expected to be echoed).

Default Implementation

This package also provides class as most-basic implementation of the TwigServiceInterface , Jascha030\Twig\TwigService.php. This class implements all three methods with the addition of a constructor requiring the Twig\Environment.

Below is a simple example of constructing the service with an Environment using the FilesystemLoader:

Development

Clone this repo, and run composer install inside the repo.

Code-style

A code-style is provided in the form of a php-cs-fixer configuration in .php-cs-fixer.dist.php. For easy execution, use the provided Composer script command.

If you have php-cs-fixer installed globally, pass it to the --config argument of the fix command.

Unit-testing

A configuration for phpunit is provided in phpunit.xml.

For easy execution, use the provided Composer script command.

If you have phpunit installed globally, and want to use that, pass the config in the --config argument.

Motivation

My personal preference is to wrap the \Twig\Environment class in a service class, which I was repeatedly writing again, while it's a very simple class.

So (finally) I added them to a simple package, complete with unit-tests.
