McMaster.Extensions.CommandLineUtils 2.1.0-beta

2.1.0: New features: - Attributes. Simplify command line argument definitions by adding attributes to a class that represents options and arguments. - Options defined as [Option] or [Argument], [Subcommand]. - Command parsing options can be defined with [Command] and [Subcmomand]. - Special options include [HelpOption] and [VersionOption]. - Async from end to end. Using C# 7.1 and attribute binding, your console app can be async from top to bottom. New API - Prompt.GetYesNo, Prompt.GetPassword, and more. Added API for interactively getting responses on the console. - Added OptionAttribute, ArgumentAttribute, CommandAttribute, SubcommandAttribute, HelpOptionAttribute, and VersionOptionAttribute. - CommandLineApplication.Execute<TApp>() - executes an app where TApp uses attributes to define its options - CommandLineApplication.ExecuteAsync<TApp>() - sample thing, but async. - CommandLineApplication.StopParsingHelpOption and StopParsingVerboseOption. When the help and verbose options are matched against a command-line flag, the parsing will stop by default. You can turn this off by setting these options if you want OnExecute to be invoked no matter what. - CommandLineApplication.ResponseFileHandling - the parser can treat arguments that begin with '@' as response files. Response files contain arguments that will be treated as if they were passed on command line. Minor bug fixes: - Add return types to .VerboseOption() and ensure .HasValue() is true when HelpOption or VerboseOption are matched - Fix a NullReferenceException in some edge cases when parsing args
