If you run arc cover it will show you who last edited the lines you have changed, which is good for deciding who should be reviewers.
Is there a way to have Arcanist automatically do this and then pre-populate the Reviewers: line in the commit message with those people?
You can get a delimited list of reviewers with this one liner:
arc cover | grep '^[^ ]' | paste -s -d, -
And you can specify reviewers when creating a diff, using the --reviewers option.
Therefore you should be able to do something like this:
arc diff --reviewers "$(arc cover | grep '^[^ ]' | paste -s -d, -)"
But this only works if you use Phabricator usernames as git author names.
