The detailed tutorial of the Chicory CLI framework and the Java class library integration
The Chicory CLI framework is an open source Java command line interface development framework. It provides a simple and powerful way to create an interactive command line tool.Its design goal is to make the development of command line tools simple and flexible, while providing rich functions and scalability.
In this tutorial, we will introduce how to integrate the Chicory CLI framework with the Java class library to create a custom command line application based on this.The following is a detailed step:
1. Preparation:
First of all, make sure your development environment is already set, and the Java Development Kit (JDK) and the Chicory CLI framework have been installed.You can get Chicory's jar package from the official website and add it to your Java project.
2. Create a Java class library:
At this step, you need to create a Java class library for your command line application.You can write logic code in the class according to your needs.
For example, let us create a simple Java class library with a method of calculating two integers.We will use this method to demonstrate in the command line application.
package com.example.mylib;
public class Calculator {
public static int add(int a, int b) {
return a + b;
}
}
3. Create command line application:
Now, we will use the Chicory CLI framework to create a command line application to call the method in our Java class library.We will create a command line app called "Calcultor" and integrate it with the Java library we previously created.
Create a new Java class in your project and name it "Calculatorapp".Then, follow the steps below:
-In introduce the necessary Chicory CLI framework library and your Java class library:
import com.scheible.chicory.Cli;
import com.scheible.chicory.ClasspathScannerCliHandler;
import com.example.mylib.Calculator;
-Coloning a import method main ():
public class CalculatorApp {
public static void main(String[] args) {
new Cli().withCommands(new ClasspathScannerCliHandler()).call(args);
}
}
-Colon a Chicory command and associate with the Java class library method:
@Commands(context = "calculator", description = "A simple calculator tool.")
public class CalculatorCommands {
@Command(description = "Add two numbers.")
public static int add(@Parameter(description = "The first number.") int a,
@Parameter(description = "The second number.") int b) {
return Calculator.add(a, b);
}
}
4. Construction and running application:
Now you have completed the integration of the Chicory CLI framework and the Java class library.By constructing and running your application, you can use the "Calculator" command on the command line and call the ADD () method in the Java class library.
-Cunge the project: Use your preferred construction tool to build projects, such as Maven or Gradle.
-Cride application: execute the following command in the command line to run your application:
java -cp <path-to-chicory.jar>:<path-to-your-class-files> CalculatorApp add 10 20
This will call the ADD () method in our Java class library, use 10 and 20 as a parameter, and print the results.
Through these simple steps, you have successfully integrated the Chicory CLI framework with the Java library and created a custom command line application.You can add more commands and functions according to your needs extension and customization applications.
I hope that this tutorial can help you understand how to use the Chicory CLI framework to integrate with the Java class library and create a powerful command line application.
