Author: kevans Date: Sat Mar 3 17:13:12 2018 New Revision: 330339 URL: https://svnweb.freebsd.org/changeset/base/330339 Log: liblua: Add loader.interpret This allows lua to pass back a command string to be executed as if it were typed at the loader prompt- loader tries to execute the string first as pure lua, then parses it and gives lua a chance to intercept before it tries to execute it itself. This will be used to implement menu_timeout_command, among other things, which *should* be used to execute basic loader commands independent of the chosen interpreter.
