(interactive "sWord to search: ") ;;(require 'grep) (rgrep myword "*\\.html" "~/web/p") ) However, if i call if for the first time, i get =E2=80=9Cgrep-expand-template: Wrong type argument: stringp, nil=E2=80=9D. But if i have used rgrep before in this session, then it works. I guess i need the (require 'grep) but that didn't help. Any hints? Thanks.
