Configgy.CommandLineParser

A Configgy extension that allows command line parsing via CommandLineParser

Usage

First setup Configgy like in the documentation.

Create a command line options class like so: (See here)

class Options {
    [Option('t', "text", HelpText="Input text")]
    public string Text { get; set; }
}

Now add the new source to your Config subclass by overwriting the default constructor:

public class MyConfig: Config, IMyConfig
{   
    public int MaxThingCount { get { return Get<int>(); } }        
    public string DatabaseConectionString { get { return Get<string>(); } }        
    public DateTime WhenToShutdown { get { return Get<DateTime>(); } }
    
    public MyConfig(string[] arguments)
        : base(
            new DictionaryCache(),
            new AggregateSource(
                new CommandLineParserSource<Options>(arguments),
                new EnvironmentVariableSource(),
                new FileSource(),
                new ConnectionStringsSource(),
                new AppSettingSource(),
                new EmbeddedResourceSource(),
                new DefaultValueAttributeSource()
            ),
            new AggregateTransformer(),
            new AggregateValidator(),
            new AggregateCoercer()
        )
    {
    }
}

This simply reproduces the normal default constructor but adds a CommandLineParserSource as one of the sources using the Options type we've already defined and gives it the arguments to parse.
