_fzf_complete_git() {
  ARGS="$@"
  CODE="$(echo $ARGS | sed 's/git checkout -b //g')"
  if [[ $CODE == "" ]]; then
    ME="-a$(jira me)"
    PROJECT_QUERY="AND project IS NOT EMPTY"
  else
    ME=""
    PROJECT_QUERY="AND project IN ($CODE)"
  fi
  local tasks
  tasks=$(jira issue list --plain --no-headers --columns key,summary $ME -q "status NOT IN (Done, Dismissed, Released, 'In Progress', 'Ready for release') $PROJECT_QUERY")
  if [[ $ARGS == 'git checkout -b'* ]]; then
    _fzf_complete --ansi --reverse --multi --prompt="fzf> " -- "git checkout -b " < <(
      echo $tasks | sed 's/[[:space:]]/-/g' | tr -dc '[:alnum:]-\n'
    )
  fi
