My employer, as of the time of this writing, has an "employee benefit" program with Bonusly, where each month Bonusly gives each employee 50 "cherries" to give away to other users (cherries you've been gifted can be redeemed for various rewards at a rate of about $0.10/cherry). At the end of the month, any cherries you haven't given away dissapear.
I always forget to give away my cherries, so I've built this automation to automatically send my coworkers cherries when they approve my PRs for merge. (Cherries are sent once per reviewer per PR.)
See the config.toml file for configuration options, and
cherries-4-prs.service for an example systemd unit file to run cherries-4-prs
in the background.
