greview

#!/bin/bash

# This script will submit all pending commits to gerrit and will automatically
# add reviewers to the associated change. Reviewers can be added by simply
# listing them after greview. You can either enter their full email addresses
# or just partially enter a unique combination of letters that will be
# fuzy-matched to either the email or the name of the commiters.
#
# Usage: greview <reviewer-1> <reviewer-2> ...

do
  pattern="$(echo "$rev" | sed 's/\(.\)/[^ ]*\1/g')"

  all_reviewers=$(echo $matches | sed -e "s/ .*//g")

    all_reviewers="$rev"
  fi

  reviewer_opts="$reviewer_opts --reviewer $all_reviewers"
done

git push --receive-pack="git-receive-pack $reviewer_opts" "$url" "$push_ref"

I think that the last lines (git config and git push) can be simplified to avoid a new remote:

git push --receivepack="git-receive-pack $reviewer_opts" "$url" "$push_ref"

Simplification of matches that is also case sensitive now:

pattern="$(echo "$rev" | sed 's/./[^ ]*./')"
matches="$(list_reviewers | grep "$pattern" | cut -d ' ' -f1)

... now I also see that this script retrieves all authors from the commit log as reviewers which could a bit slow for large repos.

Thanks for the tips! The sed expression needed a bit of change to work properly, but it's working great now. I'm also limiting the number of commits to 1000 so that there's no performance hit in large repos. =D
