Wouldn't it make sense to offer
git annex pull
which would basically do
git pull
git annex get
and
git annex push
which would do
git annex commit .
git annex put # (the proposed "send to default annex" command)
git commit -a -m "$HOST $(date +%F-%H-%M-%S)" # or similar
git push
Resulting in commands that are totally analogous to git push & pull: Sync all data from/to a remote.
Update:
This is useful:
git config [--global] alias.annex-push '!git pull && git annex add . && git annex copy . --to $REMOTE --fast --quiet && git commit -a -m "$HOST $(date +%F--%H-%M-%S-%Z)" && git push'
