[feature] conan remove should have a --dry-run option

[fschoenm]

What is your suggestion?

conan remove asks for every package if it really should be deleted. This is really bothersome when removing many packages (e.g. when removing all but the last revision with conan remove '*#!latest').

However, it would be nice to see what is deleted before actually executing conan remove -c. It would be nice to have a --dry-run option for that use cases.

Have you read the CONTRIBUTING guide?

Hi @fschoenm thanks for your request.

Do you know about the packages lists feature? (Release blog here)

It's a way to have the output of some commands be the input of a few others. See here for an example of your use case, which lets you know exactly what will be removed.

Hope this helps you with your problem, let me know otherwise :)

@RubenRBS Yes, I've heard of it but it seems awkward for such a common use case. Almost nobody is going to use such a convoluted way of doing things.

IMO every destructive command ought to have a --dry-run option.

Adding as a look-into to see what the team thinks, as I don't quite see it that way and think that our current approach is ok, will let you know once I can ask the team :)

Some of the team thinks that this might be a nice addition even when using pkglists, so we'll look into implementing it! Thanks a lot for your request!
