Sticky Revision:

Revision 2771 - Directory Listing
Modified Sat Sep 11 17:11:29 2004 UTC (15 years, 5 months ago) by dpvc
Fixed a bug with constants where the values were being cached so that
changes in the context were not being reflected in the formulas that
use them.

Revision 2658 - Directory Listing
Modified Fri Aug 20 11:17:06 2004 UTC (15 years, 6 months ago) by dpvc
Make blank patterns be ^$ (which should never match) rather than empty
(which always matches).  this fixes a problem where if a context has
no functions, for example, the parser would attempt to create function
calls to a function named ''.

Revision 2649 - Directory Listing
Modified Thu Aug 19 14:19:32 2004 UTC (15 years, 6 months ago) by dpvc
Fixed an error in the generation of regexp patterns for the various
data types.

Revision 2579 - Directory Listing
Added Mon Aug 9 21:38:01 2004 UTC (15 years, 6 months ago) by dpvc
Significant update to new parser.

New features include:

  Better control over format of vector output (you can now
    specify ijk-format rather than <...> format)

  "Fuzzy" reals, where the relations like == return true when the
    two values are "close enough".  (This is controlable using
    parameters similar to those used in NUM_CMP).

  The fuzzy reals are now used in vectors/points/matrices/complexes/intervals
    and so on so that their relations will also be fuzzy.  E.g.,
    (1E-13,2) == (0,3) will be true, and norm(Vector(0,1E-13)) will
    equal 0.

  The two main portions of the parser (the Parser and Value packages)
    now share a common context object for configuration purposes.
