meta-cli

Annotation's based {@link CommandLineParser} implementation for Command Line Interface. MetaCommandLineParser collects meta information represented via java annotations in an application's configuration class.

Simple application configuration class can be demonstrated by the code snippet below:

@CLIConfiguration(version="0", name="myApp")
public class AppConfiguration {

    @Option(description = "Simple private yes/no option without agruments", fullName = "key1", shortName = "k1")
    private boolean key1;

    @Option(description = "Simple key/value option with agruments", fullName = "keyValue1", shortName = "kv1", hasArguments = true)
    public String keyValue1;

    @Argument(index = 1, name = "infile", required = true)
    public String infile;

}

Parser analyzes User's input and creates a new AppConfiguration instance with injected values into corresponding fields.

CommandLineParser<AppConfiguration> cliParser = new MetaCommandLineParser<>();

AppConfiguration cfg = cliParser.parse(args);

or you can simply call:

AppConfiguration cfg = MetaCli.parse(args, AppConfiguration.class);

The project includes few addition tools such as Console mode initial support and well-formatted help print.
