Allow default for nested command

[jibbers42]

Is there a way to allow a default when using nested commands?

// syntax seems not allowed in yaml (from IDE message in vscode, not personally sure)
scripts:
  gen: dart run build_runner build
    del: dart run build_runner build --delete-conflicting-outputs

// this syntax is allowed, but can't call the default with derry
// (or even if I knew how, it wouldn't be more convenient than just giving it a name
scripts:
  gen:
    : dart run build_runner build
    del: dart run build_runner build --delete-conflicting-outputs

// maybe some way of making this work?
scripts:
  gen:
    - dart run build_runner build
    - del: dart run build_runner build --delete-conflicting-outputs

// or maybe derry can just reserve the name "default"?
scripts:
  gen:
    default: dart run build_runner build
    del: dart run build_runner build --delete-conflicting-outputs

Looking at the second style above, I think if derry gen could run the script with no name that would be cool - assuming there are no other issues with this approach.

Options 2/4 look the best and can probably be supported both at the same time.

yes this appears supported, i use the (scripts): on every one because i also want to have (description): on each one so my derry ls -d / derry ls --description is useful.

# this example of my version bumper, let's call this scripts.yaml and add it to the pubspec.yaml

test:
  (description): perform unit tests
  (scripts):
  - flutter test -r expanded
  # https://codewithandrea.com/articles/flutter-test-coverage/
  coverage:
    (description): produces coverage report to default coverage/lcov.info and we use genhtml to create report in coverage/html
    (scripts):
    - flutter test --coverage
    - genhtml coverage/lcov.info -o coverage/html
    - open coverage/html/index.html
  report:
    (description): produces test report to test_report/latest.json
    (scripts):
    - flutter test --reporter json --file-reporter "json:test_report/latest.json"

then try:

derry ls -d
derry test
derry test coverage
derry test report

@sonjz Nice thinking, thanks for sharing!

It would be nice for my example 2 or 4 to work since it's a bit less noise, but this seems like a workable alternative.
