status method

@override Future<FormulaStatusReport> status(FormulaContext context)

Present first, running second.

The order matters: a stopped daemon and an uninstalled one both fail the running probe, and calling the second one "stopped" would send an operator to a start button for software that is not there.

Implementation

@override
Future<FormulaStatusReport> status(FormulaContext context) async {
  final present = await validate(context);
  if (!present.valid) {
    return FormulaStatusReport(
      formula: spec.id,
      status: FormulaStatus.absent,
      message: present.message,
      checkedAt: context.now(),
    );
  }

  final step = statusStepFor(context.platform.osName);
  if (step == null) {
    return FormulaStatusReport(
      formula: spec.id,
      status: FormulaStatus.installed,
      version: present.detectedVersion,
      message: present.message,
      checkedAt: context.now(),
    );
  }

  final probe = await executor.run(step.executable, step.args);
  final detail = (probe.ok ? probe.stdout : probe.stderr).trim();
  return FormulaStatusReport(
    formula: spec.id,
    status: statusFrom(probe),
    version: present.detectedVersion,
    // One line: this is a badge's tooltip, not a log. The log is what
    // `verify` is for.
    message: detail.isEmpty ? present.message : detail.split('\n').first,
    checkedAt: context.now(),
  );
}
