FWIW, OpenLaszlo has a fairly complete implementation of 'printf': http://svn.openlaszlo.org/openlaszlo/trunk/WEB-INF/lps/lfc/compiler/LzFormatter.lzs created long before the quasis proposal (which is quite nice). I agree there needs to be a way to direct _how_ the value is interpolated, and I suspect this is what the comment "Meta data can be attached using a syntactic convention chosen by the quasi function" is meant to hint at. An example along the lines of printf format control might be nice... _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
