Remember what you've done since your last standup

gistfile1.sh

# zsh script checks first if there were any commits done
#   by author yesterday. If there were, return those. If
#   there weren't, look for all commits since last Friday
#   at midnight as it may have been a weekend.
#
# Use your name in the --author for all commands

gitstandup() {
  if [ -z "$(git log --all --pretty=format:'* %s' --no-merges --reverse --author=Justin --since=yesterday.midnight)" ]; then
    git log --all --pretty=format:'* %s' --no-merges --reverse --author=Justin --since=last.friday.midnight;
  else
    git log --all --pretty=format:'* %s' --no-merges --reverse --author=Justin --since=yesterday.midnight;
  fi
}

Awesome script!
I made a variation here: https://gist.github.com/ConorSheehan1/f6da062b536c633622e1aa438aa64593

Changes:

1. Get user with git config user.email
2. Pass extra args to functions with $@
3. Add example git aliases (in comments)
4. Add explicit day check using GNU coreutils date (in comments)
