River Tarnell	6ba4846e05	need type_name here too	2008-08-13 17:16:22 +00:00
River Tarnell	0834126abc	provide nicer type names in error messages	2008-08-13 16:42:18 +00:00
River Tarnell	4f6c4d886e	- parser: support singular for time units as well as plural ... - visitors: remove commented code	2008-08-12 12:17:56 +00:00
River Tarnell	d4d3f27224	rewrote most of visitors.h, and split functors into functors.h. this implementation uses a metaprogram to determine valid operators at compile time, instead of requiring every exception to be specified seperately.	2008-08-12 12:11:31 +00:00
River Tarnell	4a4e3166cd	initial support for dates and intervals	2008-08-11 22:09:34 +00:00
River Tarnell	41afd40801	change from double/float to GMP arbitrary precision types. as well as increased range, this means '1.3 + 20' no longer evaluates to '21.300000000000001'	2008-08-11 01:01:05 +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	5037acbd0d	Unicode conversion: full Unicode support for parser, and 'expr' tool ... add UTF-8/UTF-32 conversion functions for input/output	2008-08-09 16:18:04 +00:00
River Tarnell	eb5586854e	Unicode conversion, phase1: datum should be templated on char type. ... added basic_datum<charT>, with typedefs datum and u32datum	2008-08-09 13:37:58 +00:00
