bringert	3dacf21a41	Use makeSimpleSRG everywhere and remove makeSRG. Reimplemented top-down filtering in terms of CFRules instead of SRG. Do top-down filtering in makeSimpleSRG.	2007-03-19 18:03:19 +00:00

bringert	efb806f226	SISR code now type annotates meta variables directly in grammar, to avoid a separate type annotation step.	2007-01-05 17:34:44 +00:00
bringert	6ee7296f9d	Changed all SRG printer to take Options and StateGrammar arguments. This makes Custom a lot cleaner.	2007-01-05 15:38:47 +00:00
bringert	741dde5a2a	Change input to the different SRG printers to be StateGrammar instead of CGrammar. This to allow looking at the types in SISR, and to reduce the number of argument passed from Custom.	2007-01-05 14:34:20 +00:00
bringert	7577149241	SISR: constants from conversion=finite now produce abstract syntax nodes instead of strings.	2007-01-03 22:57:20 +00:00
bringert	a335b29c0a	Meta variables are now treated as functions with name ? in SISR, VoiceXML and JavaScript linearization. VoiceXML now returns the partial result when update() is false.	2006-12-21 16:48:46 +00:00
bringert	f9621483a0	Use LCLR algorithm for eliminating left-recursion, with lambda terms in SISR for getting trees right.	2006-12-20 20:10:15 +00:00
bringert	c7df9f4167	Added still unused implementation of Moore's LCLR algorithm for left recursion elimination. Fixed top category generation for SRG (included LR-elimination-added categories before).	2006-12-17 19:18:28 +00:00
