Feature Request: Allow sync (or bumps) for specific dependencies

[ciriarte]

Context

vendir currently supports the --directory flag:

$ vendir sync -d my_dependency

But it doesn't save the lock file. I would like vendir to be able to isolate sync/bumps to a specific dependency.

Hey @ciriarte!
Let us know if this captures your intent.

Currently vendir sync only syncs an entire vendir.yml file.
You can use vendir sync --directory to override contents of particular directories by pointing them to local directories. However, this does not update the lock file.

To support syncing only a subset of the dependencies in the vendir.yml, vendir sync would provide the ability to target the given dependencies, and update the vendir.lock.yml with the new metadata.

@ciriarte we wouldnt expect to modify anything other dependencies -- even if they were modified on disk, intentionally or unintentionally -- right?

My expectation is that vendir will only update the directory it is managing and I've instructed in the vendir sync -d some_dir call.

My understanding is that vendir sync -d has a couple of options per the help command:

1. It does sync local dirs if used with dir/sub-dir[=local-dir] I'm not really interested in this workflow at the moment 🚫
2. It synchronizes with a remote if the optional [=local-dir] is omitted. This does something close to my desired outcome ✅

If my understanding of 2 is correct, then you captured my wishes perfectly in the following sentence:
