More fixes for creating items in the corret context.  Also added a
method for looking up the package associated with a particular Parser
class (for consistency with the Value->Package call).

Update to handle the fact that the Value package now includes the
context with all MathObjects.  (This may still need some work.)

A first pass at making parser error messages localizable.  The
Context()->{error}{msg} hash can be used to specify translations of
the standard messages.  For example,

    Context()->{error}{msg}{'Division by zero'} = "Don't divide by zero, dude!";
    Context()->{error}{msg}{'Function '%s' has too many inputs'} =
        "You passed too many arguments to '%s'";

(I didn't translate into another language, here, but you could do
that, too.)

The msg hash could also be used within answer checkers to make certain
answer messages more appropriate for the given type of expected answer.

Make sure equality always returns a defined value, and
put spaces around the equal sign in string output.

Revision 2616 - (view) (download) (as text) (annotate) - [select for diffs]
Added Sat Aug 14 21:29:21 2004 UTC (8 years, 9 months ago) by dpvc
File length: 1679 byte(s)

Added an equality operator (not active initially) that can be used for
things like equations of planes and so on.  I'm working on the answer
checker for that.
