CommandLiners.Posix 1.0.45

POSIX Command Line Provider

This is a drop-in replacement for the CommandLineProvider following the POSIX guidelines for the command-line options of a program.

var builder = new ConfigurationBuilder()
    .AddCommandLineOptions(args.ToPosix())
    .Build();

var options = new Options();
builder.Bind(options);

Flag arguments

var args = new[] { "-dl" };

var builder = new ConfigurationBuilder()
    .AddCommandLineOptions(args.ToPosix(map => map
        .Add("d", o => o.Debug)
        .Add("l", o => Options.Log)));
    .Build();

Unnamed arguments

var args = new[] {"my-value-1", "my-value-2", "my-value-3"};
var builder = new ConfigurationBuilder()
    .AddCommandLineOptions(args.ToPosix(map => map.Operands(o => o.Files)))
    .Build();

Multiples

Options can be repeated when the value accepts a list of inputs:

var args = new[] { "--input-file", "my-value-1", "--input-file", "my-value-2", "--input-file", "my-value-3"};
var builder = new ConfigurationBuilder()
    .AddCommandLineOptions(args.ToPosix())
    .Build();

Opposed to the CommandLineProvider:

var args = new[] { "--input-file:0", "my-value-1", "--input-file:1", "my-value-2", "--input-file:2", "my-value-3"};
var builder = new ConfigurationBuilder()
    .AddCommandLine(args)
    .Build();
