Description:

wrapper args

A library for Dart command-line.
Parses raw command-line arguments into a set of options and values. Wrapper package:args/args.dart for my style

Usage #
A simple usage example:
import 'package:wrapper_args/wrapper_args.dart';

main(List<String> arguments) {
// create root command
final root = _root();

// create subcommand
root.addCommand([
_server(),
_client(),
]);

// parse and execute
root.parseAndExecute(arguments);
}

Command _root() {
final parser = ArgParser()
..addFlag(
"help",
abbr: "h",
negatable: false,
help: "Print this usage information",
)
..addFlag(
"version",
abbr: "v",
negatable: false,
help: "Print the version",
);
return Command(
help: "Usage: wrapper_args [<subcommand>] [<options>]",
parser: parser,
execute: (command, results) {
if (results["help"]) {
print("${command.usage}");
} else if (results["version"]) {
print("version 1.0.0");
}
},
);
}

Command _server() {
final parser = ArgParser()
..addFlag(
"help",
abbr: "h",
negatable: false,
help: "Print this usage information",
)
..addOption(
"listen",
abbr: "l",
help: "tcp listen address",
);
return Command(
name: "server",
help: "simulator server",
parser: parser,
execute: (command, results) {
if (results["help"]) {
print(command.usage);
} else {
print("server work at ${results['listen']}");
}
},
);
}

Command _client() {
final parser = ArgParser()
..addFlag(
"help",
abbr: "h",
negatable: false,
help: "Print this usage information",
)
..addOption(
"target",
abbr: "t",
help: "connect target",
);
return Command(
name: "client",
help: "simulator client",
parser: parser,

if (results["help"]) {
print(command.usage);
} else {
print("connet ${results['target']} ...");
