River Tarnell	aa982fce43	- using leaf_node_t includes the skip parser in the parsed token, causing expressions like (1 == ONE) to fail. use reduced_node_t instead ... - add regression test framework and some basic tests	2008-08-10 20:38:52 +00:00
River Tarnell	bbf1737cc2	- convert parser to AST. while this is slower than the previous implementation, it's clearer, and more correct (lazy evaluation is supported) ... - to compensate for the slower parser, optimised it a little - change basic_string to fray, a refcounted immutable string - add 'xml' tool, prints the parser tree in XML	2008-08-10 03:52:17 +00:00
River Tarnell	4eda47daab	add 'expr' tool	2008-08-09 16:22:21 +00:00
