Hahaha the CI build fails because there's the same problem in another package:

Installing package default

~/.local/share/omf/pkg/omf/functions/bundle/omf.bundle.add.fish (line 11): Expected a string, but instead found a '&'

    if not grep $record $bundle > /dev/null ^&1

Guess this is going to take some time to sort out...

Don't you need to update fish version in the travis config (as it's currently on 2.2) and switch the omf channel to dev omf channel dev to get this working?

Thanks for sending the pull request! I have incorporated this fix on #19, hence I'm closing this one.
