Chicory CLI: The command line framework in the Java class library
Overview:
Chicory CLI (Chinese translation is a chrysanthemum command line interface) is a Java class library for developing command line interfaces.It provides a simple and powerful way to create an interactive command line application, enabling developers to easily build applications with characteristics such as command analysis, automatic completion function, and command history.This article will introduce the main characteristics and usage methods of Chicory Cli, and provide some Java code examples.
Features:
1. Simple and easy to use: Chicory CLI provides simple and easy -to -understand APIs, enabling developers to quickly get started and create a functional command line application.
2. Command analysis: Chicory Cli can analyze and execute command line parameters, supporting various types of parameters, including string, integer, Boolean value, etc.
3. Command complement: This framework provides automatic completion function, which can automatically match and complete commands, options and parameters according to the user's input to enhance the user experience.
4. Order historical records: Chicory CLI allows users to browse and execute orders before the command line interface, so that users can easily find and repeat the order of the previous execution.
5. Error treatment: The framework provides an error processing mechanism that can capture and process errors in the input of command lines to ensure the stability and reliability of the application.
Example:
Below is a simple example code that shows how to use the Chicory CLI to create a command line application with two commands.
import com.github.saka1029.chicory.Command;
import com.github.saka1029.chicory.MethodArgumentException;
import com.github.saka1029.chicory.Option;
import com.github.saka1029.chicory.Parser;
import com.github.saka1029.chicory.Result;
public class MyApp {
@Command
public static void sayHello(@Option("-n") String name) {
System.out.println("Hello, " + name + "!");
}
@Command
public static void calculate(@Option("-a") int a, @Option("-b") int b) {
int result = a + b;
System.out.println("Result: " + result);
}
public static void main(String[] args) {
Parser.parse(MyApp.class, args).run();
}
}
In the above examples, we created a Java class called `MyApp`, which contains two methods to use the method of annotating labeling` Sayhello` and `Calculating.`Sayhello` Method accepts a string parameter called` name`, and the `Calculate` method accepts two integer parameters,` a` and `b`.By using the `@option` annotation marker parameter, we can specify these options in the command line.
In the `Main` method, we use the` PARSE` method of the `Parser` class to resolve the command line parameters to the corresponding method, and then use the` Run` method to execute the corresponding command.
Summarize:
Chicory CLI is a convenient and powerful Java class library that helps developers to quickly build an interactive command line application.It provides characteristics such as command analysis, automatic completion function, and command history, which can greatly simplify the development process of command line applications.With the Chicory CLI, developers can easily create a rich and easy -to -use command line interface.
