Reorganize the CLI structure ?

[alexkharech]

I propose to reorganize the CLI structure, there are not many functions yet.
it would be wise to store commands in the map

import './commands/init/init.dart';
import './commands/create/project/project.dart';
import './commands/create/page/page.dart';
import './commands/create/view/view.dart';
import './commands/generate/locales/locales.dart';
import './commands/install/install.dart';
import './commands/version/version.dart';

const commands = {
  'init': initCommand,
  'create': {
    'project': createProjectCommand,
    'page': createPageCommand,
    'view': createViewCommand,
    ...
  },
  'generate': {
    'locales': generateLocalesCommand,
    ...
  },
  'install': installCommand,
  '-v', versionCommand, // change to `version`, to have the same structure everywhere?
  '-version', versionCommand, // and remove this alias?
  ...
};

// map for help in console 
const hints = {
  'init': 'generate the chosen structure on an existing project',
  'create': {
    'project': 'create a flutter project in the current directory',
    ...
  },
  ...
};

running the command can generate multiple files

./commands/create/page/samples/controller.dart
./commands/create/page/samples/binding.dart
./commands/create/page/samples/view.dart

Motivation:

• All commands have one clear structure.
• To add a new command, you need to create a separate independent directory.
• Easily generate help in the console.
• It is easy to check that the command exists and at this nesting level is a function.
• Easy to expand functionality name unlimited command nesting.

Commands should extend the abstract class, which is a generator and requires the implementation of the necessary functionality.

Over the weekend I will work on it

[CpdnCristiano]

I'm currently a little busy with other tasks

[alexkharech]

maybe something similar?
i can help migrate existing features over the weekend

abstract class Command {
  /// hint for console
  String get hint;

  /// validate command line arguments
  bool validate();

  /// execute command
  Future<void> execute();
}

class ExampleCommand extends Command {
  String get hint => throw UnimplementedError();

  @override
  bool validate() {
    // TODO: implement validate
    throw UnimplementedError();
  }

  @override
  Future<void> execute() {
    // TODO: implement execute
    throw UnimplementedError();
  }
}

void main() {
  final commands = {
    'create': {
      'example': () => ExampleCommand(),
    }
  };

  final hints = {
    'create': {
      'example': ExampleCommand().hint,
    }
  };

  // find command by arguments
  final command = commands['...']['...']();

  // print errors
  if (command.validate()) {
    command.execute();
  }
}

I am very grateful for your help

[alexkharech]

@CpdnCristiano I have implemented the api I suggested. Where can I show an idea? this is from a clean project

[CpdnCristiano]

if you want you can create a repository on github

[CpdnCristiano]

very good, I liked it a lot I will implement it as soon as possible

[CpdnCristiano]

implemented some of your tips
