influx-cli

Influx CLI provides a flexible way to bind command line arguments to Java objects. Annotations are used to map command line interface to your data structure. The result is very concise code which reduces the boilerplate which is required to parse and validate command line arguments.

Why should you use this?

• Library not a framework
• No dependencies
• Permissive licensing
• Versatility
• Ease of use
• Free

Getting started

Maven

<dependency>
    <groupId>org.voidzero</groupId>
    <artifactId>influx-cli</artifactId>
    <version>0.13.0</version>
</dependency>

Example

import org.voidzero.influx.cli.annotation.Command;
import org.voidzero.influx.cli.annotation.Arg;
import org.voidzero.influx.cli.InfluxCli;

@Command(
        openingText = "This is the opening text",
        closingText = "This is the closing text."
)
public class Example {
    @Arg(code = 'f')
    private String firstName;

    @Arg(code = 'l')
    private String lastName;

    public static void main(String[] args) {
        Example example = (Example) new InfluxCli().bindOrExit(Example.class, args);
        System.out.printf("Hello, %s %s!\n", example.firstName, example.lastName);
    }
}

The following is output when --help is passed into the above program:

This is the opening text
  -f  --first-name  Accepts a string value
  -l  --last-name   Accepts a string value
This is the closing text.

The following is output when --first-name John --last-name Dunlap is passed into the above program:

Hello, John Dunlap!
