page pagename = nt1, nt2, nt3; which puts the descriptions of nonterminals nt1, nt2 and nt3 on a single page. The index page now contains two indicies .. the 'topic' index has entries like 'addition', 'logic' 'bitwise' and 'regular_expressions' which are pages of grouped non-terminals. I'm considering 'tree structure' for the pages too: for example in the page description: sproduct := expressions | s_term * sproduct_list expressions | s_term sproduct_list := expressions | s_term ( * s_term)* the sproduct_list is entirely a 'local' nonterminal, used ONLY in the sproduct production. The actual grammar here is just sproduct := s_term (* s_term)* but it is split up as shown for historical reasons. In this case, the sproduct_list should probably be indented to show it is local to sproduct. It actually makes some sense to add a new feature to the grammar like: let syntax sproduct_list := ... in sproduct := .. or sproduct := .. where sproduct_list ... For the same reason, dssl's probably need 'private' nonterminals. Finally, I split up some lists like: s1 = ... s1 = ... s1 = some ... s1 = ... into s1 = mysome mysome = some ... s1 = ... ... to force some productions into a separate group. This is the opposite of the 'page' command. However it has real semantics: * it causes merges to be done on the new branch mysome first, before the merging on s1, so it is NOT equivalent * it also causes extra (useless) reductions to be performed Priorities could fix the latter. The former effect may or may not actually be desirable! -- John Skaller <skaller at users dot sf dot net> Felix, successor to C++: http://felix.sf.net ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
