{% capture billboard_description %}
The Spring Shell project provides an interactive shell that allows you to
plugin your own custom commands using a Spring based programming model.
{% endcapture %}
{% capture main_content %}
## Introduction
Users of the Spring Shell project can easily build a full featured shell ( *aka* command line)
application by depending on the Spring Shell jar and adding their own commands (which come as
methods on spring beans). Creating a command line application can be useful *e.g.* to
interact with your project's REST API, or to work with local file content.
## Features
Spring Shell's features include
* A simple, annotation driven, programming model to contribute custom commands
* Use of Spring's classpath scanning functionality as the basis for a command plugin strategy and command development
* Tab completion, colorization, and script execution
* Customization of command prompt, banner, shell history file name
* Dynamic enablement of commands based on domain specific criteria
* Already built-in commands, such as clear screen, help, exit, *etc.*

## Quick Start
{% include download_widget.md %}
Then to create a simple command that could be invoked as
```
shell:>translate "hello world!" --from en_US --to fr_FR
bonjour monde!
```
assuming you'd have access to some kind of translation service that worked with Locales:
```java
package foo;
import foo;
@CommandMarker
public class TranslationCommands {
private final TranslationService service;
@Autowired
public TranslationCommands(TranslationService service) {
this.service = service;
}
@CliCommand(value = "translate", help = "translate text from one language to another")
public String translate(@CliOption(key = {"", "text"}) String text,
@CliOption(key = "from", unspecifiedDefaultValue = "en_US") Locale from,
@CliOption(key = "to") Locate to
) {
// Check args, etc.
// invoke service
return service.translate(text, from, to);
}
}
```
