Revision 4928 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Tue Apr 17 00:36:16 2007 UTC (12 years, 8 months ago) by dpvc
File length: 14807 byte(s)
Diff to previous 4806
Modified the way the Parser-based versions of the traditional answer
checkers get copies of their contexts.  They now use a new method
getCopy to obtain the copy either from the problem's context table or
the default table (rather than only from the default).  That way the
instructor can use parserCustomization.pl to customize the contexts
used by the answer checkers.

File length: 14838 byte(s)
Diff to previous 3557
Added ability to specify variables that are part of the union/list
rather than requiring just constants.  E.g.,

       interval_cmp("(1,a),(2a-1,a)",unions=>'no',var=>'a');

or

       interval_cmp("(x,y),(2x,3y)",unions=>'no',vars=>['x','y']);

Default behavior of number_list_cmp set to be backward compatible
(no hints of any kind or partial credit).  These features can now be
activated by optional arguments.

Also improvements on parser-based interval_cmp.

Hopefully improved some of how the temporary context is set for number_list_cmp.

interval_cmp which uses Parser, temporarily called interval_cmp2.
