run a script in reverse topological order

Is it possible to run lerna in reverse topological order?

e.g.

-packages
  +-A (depends on B, C)
  +-B
  +-C

lerna run undeploy would first run ‘undeploy’ on A, then B & C.

B or C cannot be removed first as it would leave A depending on non-deployed packages.

[evocateur]

npx lerna -v
# 3.18.1

# macos default userland
npx lerna ls --toposort | tail -r

# gnu / brew install coreutils
npx lerna ls --toposort | tac

Pipe that list to whatever, and there you go, reverse topological order:

npx lerna ls --toposort | tac | xargs -I % npx lerna run --scope % my-awesome-task

(remove npx if you’re running this in an npm script lifecycle)

Hi Folks 👋

You will have seen in our message above that we at Nrwl are working really hard to bring the lerna repo up to date with what matters most to its community in June 2022.

As previously stated in that message, because we have not heard from the original author of this issue within the last 14 days, we are now automatically closing it.

All we ask is that you first update to the latest lerna (5.1.4 at the time of writing) to make sure it is still reproducible, and then fill out one of our new issue templates, providing all the requested details which apply to your situation:
