Add LIT and LSTR to the switch statement + so that literals an lazy strings are handled if they occur. + (do_output_line): Add LIT and LSTR to switch. + +2013-10-27 Kaz Kylheku <kaz@kylheku.com> + * genvim.txr: Include syntactic directives which aren't extracted from sources because actions aren't registered for them. |
