kevmoo / build_cli Goto Github PK

Currently it errors:

Could not handle field `userIds`. Lists of type `int` are not supported.
package:dart_admin/commands/client_updater.dart:22:18
   ╷
22 │   late List<int> userIds;
   │                  ^^^^^^^
   ╵

is there a way with build_cli to use addCommand ? if yes how ?

thanks

I have an option defined like this:

  @CliOption()
  final int? maxKeep;

Which generates the following parser code:

maxKeep: int.tryParse(result['max-keep'] as String) ??
    _$badNumberFormat(
      result['max-keep'] as String,
      'int',
      'max-keep',
    ),

This code has a problem. As I do not define a default value for the CLI option, result['max-keep'] actually returns null, which cannot be cast to a string and thus throws an exception:

Unhandled exception:
type 'Null' is not a subtype of type 'String' in type cast
#0      _$parseOptionsResult (package:podman_backup/src/cli/options.g.dart:45:48)
#1      Options.parseOptions (package:podman_backup/src/cli/options.dart:203:7)

Please fix this problem by adding a null check. Something like the following could work:

maxKeep: result['max-keep'] != null 
  ? int.tryParse(result['max-keep'] as String) ??
    _$badNumberFormat(
      result['max-keep'] as String,
      'int',
      'max-keep',
    )
  : null,

Would like to use build_cli together with analyzer ^6.0.0

• Dart SDK : 2.0.0-dev.69.2 (Mon Jul 23 17:10:56 2018 +0200) on "windows_x64"
• build_cli : 0.2.4+1

I'm using packages json_annotation v1.0.0 and json_serializable v1.0.0 to add JSON support to some model classes to a project providing an executable that uses build_cli.

These packages rely on source_gen v0.9.0 but build_cli rely on v0.8.2. So I can't install the project dependencies :

$ pub get
Resolving dependencies...
Because build_cli >=0.2.4 depends on source_gen ^0.8.2 and json_serializable >=1.0.0 depends on source_gen ^0.9.0, build_cli >=0.2.4 is incompatible with json_serializable >=1.0.0.
So, because my_app depends on both json_serializable ^1.0.0 and build_cli ^0.2.4, version solving failed.

Now, build_cli can't generate code which matched this:

// file.dart
import 'package:args/args.dart';

void main(Iterable<String> args) {
  final parser = new ArgParser()..addFlag('test', defaultsTo: null, negatable: true);
  final results = parser.parse(args);
  print(results['test']);
}

dart file.dart
// null

In my case, I don't want to have a true or false value. I want to have null. But I can't have it.

Warn during generation?
Improve error when parsing?
