loadCommandConfig function

Future<BPConfig?> loadCommandConfig(
  1. List<String> args,
  2. HelpCommand command
)

Handles the --help flag, reads the config, and prints the problems found in it

The problems are printed in the output chosen by the user, which is known from the flag even when the config could not be read. Returns null when the command cannot run, after printing why

Implementation

Future<BPConfig?> loadCommandConfig(List<String> args, HelpCommand command) async {
  // Handling the command's --help flag
  handleCommandHelpFlag(args, command);

  (BPConfig?, List<BPConfigValidationError>) configAndErrors = await BPConfig.readPubspec(args);

  OutputMode output = configAndErrors.$1?.output ?? OutputMode.fromArgs(args).$1 ?? OutputMode.auto;
  Console.json = output == OutputMode.json;

  // Printing the errors that were found while parsing the config
  // If the error are fatal the config will be null
  for (BPConfigValidationError error in configAndErrors.$2) {
    error.print();
  }
  return configAndErrors.$1;
}
