FAQ
Example:
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 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.

CLI App
CLI App is a template for creating console applications based on Symfony Console and the Herrera.io Service Container. Think Silex, but for console applications, and easier.
Example

Installation

Usage
Creating a new application is as simple as instantiating the Application
class. The class itself is an extension of the Container class from the
Herrera.io service container library.
The purpose of
app.nameandapp.versionwill be later discussed in the section titled Configuration. It is one of many customizable options for the application.
Default Services
When the application is instantiated two services are registered:
Herrera\Cli\Provider\ErrorHandlingServiceProvider— Replaces the current error handler with one provided by the service. The custom error handler will simply convert all errors into instances ofErrorExceptionand throw them. The handler will respect the currenterror_reporting()setting.Herrera\Cli\Provider\ConsoleServiceProvider— The console service provider that is used by the application to configure, add commands, add helpers, and run.
The Application class is designed so that you can replace the default
registered services by overriding a single method. You can also extend
the method to register additional default services.
Adding a Command
To add a new command to the application, you will need to call the add()
method. This method will create a new command and return it for further,
optional, configuration. The command returned is an instance of the
Symfony\Component\Console\Command\Command class.
Adding a Helper
To add a helper to the application, you will need to call the set() method.
This method will register the helper with the current helper set. Any instance
of Symfony\Component\Console\Helper\HelperInterface is accepted.
App Container as Helper
The Application container is registered as a helper in the console instance.
This will make it easier to access the container in order to use other services
within a command that extends the Command class.
Running
Running the application is simple:
If auto exiting is disabled, $status will hold the exit status code.
Configuration
The majority of the all available configuration parameters and servics lie
within the ConsoleServiceProvider that is registered with the Application
service container. The default parameters and services can be modified until
the console service is used. Any further changes will not take any effect.
These are the default console parameters:
