ECF v1.0.2

Changelog:

• fixed error message for command not found (using help command as default)

ECF v1.0.1 - Async commands, DevOps tasks and more

Note: Changes are backward compatible for standard usage scenarios (i.e. using ECFHostBuilder and CommandBase classes).

1. Linux users, I've got something for you

• problematic system32.CommandLineToArgW was rewritten to fully support Linux builds

2. ECF is now fully asynchronous

• added new base class AsyncCommandBase, which allow to utilize async behaviour
  • use CancellationToken for graceful interruption
  • CommandBase is now wrapping AsyncCommandBase to reflect old behavior
• ICommand has new interface
  • definition of Execute changed to Task ExecuteAsync(CommandArguments args, CancellationToken cancellationToken)
  • definition ApplyArguments has been removed (it is still used internally inside AsyncCommandBase)
  • CancellationToken need to be handled for graceful interruption, for generic use I recommend putting cancellationToken.Register(() => Environment.Exit(1))
• CTRL + C now tries to interrupt current command instead of interrupting whole program
  • For ICommand and AsyncCommandBase token will be cancelled. If token is not handled, command will run despite cancel signal.
  • For CommandBase this will invoke Environment.Exit(1)
  • Pressing CTRL + C twice will result in calling Environment.Exit(1) in any scenario
• Updated BaseKit commands to new async behavior, including LoadScriptCommand, along with ScriptLoader.

3. Now ECF is more suitable for DevOps tasks with arrival of Default Commands

• this new approach is designed to modify ECF console application, to be used as a part of pipeline process, which does not support passing CLI arguments (or it's just really inconvenient)
  • yes, you've guessed it: I've encountered this scenario during one of my projects :)
  • the main advantage of this approach, in contrast to using simple console application, is that you can utilize IoC and already constructed ECF commands for those tasks
• added ECFHostBuilder.UseSingleCommand<TCommand>(), which will enforce program to run only command you've specified (default command + no prompt mode + no commands in registry)
  • example configuration should looks like this

    await new ECFHostBuilder()
    #if ENV_build_for_very_annoying_devops
        .UseSingleCommand<Example.Commands.TestProgressBar_Asynchronous>()
    #else 
        .UseDefaultCommands()
    #endif
        .RunAsync(args);
    

• added DefaultCommand option in InterfaceContext (not necessary when using UseSingleCommand)
  • note: keep in mind that command mapping comes first, so program.exe hello john will first check if command hello exits and tries to invoke it with args ["john"], if there is no such command it will invoke default command with args ["hello", "john"]
  • CommandArguments now have new property ExecutedAsDefaultCommand which will indicate if command was invoked via fallback mechanism: when no arguments were passed or when command name was not found by matching first argument
• added DisablePrompting inside InterfaceContext (true when using UseSingleCommand), which will invoke default command, instead of prompt mode, when program started without arguments
• removed not found message from core engine
  • NotFoundCommand was merged into HelpCommand, it now utilize ExecutedAsDefaultCommand to whenever display command not found or not
  • UseDefaultCommands() now sets HelpCommand as default command (if not set already)
  • if your ECF program does not invoke UseDefaultCommands() and you want to restore old NotFoundCommand behavior please set ctx.DefaultCommand = typeof(ECF.BaseKitCommands.HelpCommand) in your .Configure((ctx, services, _) => section

4. Help is now more helpful

• now every CommandBase and AsyncCommandBase will react to -h and --help with displaying help message (same as help commandname)
• now command syntax, if not set by attribute, will be generated automatically based on argument bindings
• some visual changes to reduce fuss and focus on actual help content

5. Other changes

• added RequiredAttribute to use with [Argument]/[Parameter]/[Flag], which will prevent command from running if not set by user (CommandBase, AsyncCommandBase)
• added support for nullables in binded properties (CommandBase, AsyncCommandBase | [Argument], [Parameter], [Flag] )
• added option for specifying StringComparison, defaults to StringComparison.InvariantCulture (CommandBase, AsyncCommandBase | [Argument], [Parameter], [Flag] )
• new constructor for [Flag]s and [Paremeter]s
  • [Flag(ShortName="f", LongName="flag")] => [Flag("-f --flag")]/[Flag("-f", "--flag")]
  • This will allow to change prefix aswell (eg. ~~tilde-flag)
• added option to alter default behavior of ignoring values with prefixes (CommandBase, AsyncCommandBase | [Argument], [Parameter] )
  • by default all arguments and parameters with prefix - will be ignored
  • you can disable all prefixes by providing ForbiddenValuePrefixes = new string[0]
• now all ECF exceptions inherit from ECFException which can help you managing exception better in your application
• prefix from InterfaceContext now does not include space after, which can be added to maintain old behavior. (Marking this as breaking change because it can break some automated tests)
• (advanced) AddECFCommandRegistry now uses configure Action inside extension method to register commands
  • New example for creating ICommandProcessor looks like this:

    public ICommandProcessor CreateDirectionCommandsProcessor(InterfaceContext interfaceContext)
    {
        // CommandProcessors hold IoC containers to maintain seperate collection of services        
    
        return new ServiceCollection()
            // when using alternative scope, we need to build command registry manually
            .AddECFCommandRegistry(interfaceContext, builder => builder
                .RegisterCommands<DirectionCommandAttribute>(Assembly.GetExecutingAssembly()) // we can register all commands with  specified attribute in specified assembly
                .RegisterCommands<CommandAttribute>(typeof(HelpCommand).Assembly) // this line will register basic commands as  HelpCommand, LoadCommand etc.
                .Register<CommandAttribute>(typeof(ExitCommand)) // alternatively you can always register commands seperatly one by one
                .Register(typeof(ExitCommand), "exit")) // or even register without attribute (it can cause issues with help command)
            .BuildAndCreateECFCommandProcessor(); // at the end we need to construct CommandProcesor which will process command  requests
    }

ECF v0.2.3 - AsyncCommandBase & auto syntax & .NET 8.0

• Added AsyncCommandBase which is basically wrapper for ExecuteAsync().Wait() but it will be used in future if more sophisticated async management will be in place. For now I cannot see any benefit in propagating asynchronous behavior up to CommandProcessor. Maybe I will change my mind later.
• Added auto-generated syntax when no [CmdSyntax(...)] is provided.
• Added support for .NET 8
