Chicory CLI: Command Line Interface Development Box in Java Class Library
Overview:
Chicory CLI is a command line interface (CLI) development framework for Java application development. It provides a simple and powerful way to create an interactive command-line interface for interacting with users, executing commands, and displaying results.
Command line interface is a common user interface that is particularly suitable for developing operating system tools, management tools, and other applications that require interaction through commands. Chicory CLI provides a highly customizable framework to simplify the development process of command line interfaces.
Functional features:
The following are some functional features of the Chicory CLI:
1. Command parsing: The Chicory CLI can parse command line parameters and options, parsing user input into usable data structures. It supports the definition, validation, and parsing of options, as well as automatic completion of parameters.
2. Command execution: The Chicory CLI allows developers to define and execute commands. Each command can be associated with an execution method or operation. This framework provides a convenient way to handle the execution process of commands, including the input parameters and output results of commands.
3. Command History: The Chicory CLI provides command history recording functionality, allowing users to access previously executed commands in an interactive interface. Users can use the up and down arrows to traverse historical commands and re execute or modify them.
4. Command completion: The Chicory CLI supports automatic command completion. When a user enters a command or option, it can automatically display possible options and parameter values, providing a better user experience.
5. Interface Customization: The Chicory CLI allows developers to customize the appearance and behavior of the command-line interface. It provides flexible options to set interface related properties such as prompts, colors, and output formats.
Example code:
The following is a simple example that demonstrates how to use the Chicory CLI framework to create a command line interface that includes some commands:
import io.chicymi.cli.CLI;
import io.chicymi.cli.Command;
import io.chicymi.cli.CommandContext;
public class MyCLI {
public static void main(String[] args) {
CLI cli = new CLI();
//Define a command
Command greetCommand = new Command("greet", "Say hello to the user", (ctx) -> {
String name=ctx. getArgument ("name")// Get Command Parameters
System.out.println("Hello, " + name + "!");
});
//Adding commands to the CLI
cli.addCommand(greetCommand);
//Running CLI
cli.run();
}
}
In the above example, we created a simple CLI instance and added a command called 'green'. This command takes a parameter named 'name' and prints the corresponding greeting on the console. Finally, we launch the command line interface by calling 'cli. run()'.
Through this simple approach, the Chicory CLI framework allows for easy creation and management of command line interfaces, enabling users to interact with applications and perform various command operations.
