Revision 880 - Directory Listing
Modified Thu May 22 16:19:49 2003 UTC (10 years ago) by apizer

rename course access_log to answer_log so that it will not be confused with the system access log.

Revision 856 - Directory Listing
Modified Fri May 16 23:30:46 2003 UTC (10 years ago) by jj

Added global variable for default delimiters/vertical lines in display_matrix.

---

Revision 767 - Directory Listing
Modified Sun Mar 2 21:07:24 2003 UTC (10 years, 2 months ago) by gage

Added the preprocessing facility.

The current default preprocessor is a filter which takes the initial PG problem
and handles the BEGIN_TEXT/END_TEXT blocks as well as escaping backslashes and
replacing ~~ by backslash.

Other preprocessors can be installed to effect different behavior.

At present there is only one preprocessor.  The behavior of the method
preprocess could be modified to allow a chain of preprocessing filters
if that becomes desirable.

The barest bones of a postprocessing facility is also in place.  The
current default postprocessor does nothing.  This could be implemented
to create sticky answers.

Modified Sat Nov 9 19:39:49 2002 UTC (10 years, 6 months ago) by gage

Added some code setting METAFONT_DPI=180 to remove a division by zero

set correctly

Commented out use PGtranslator.

replaced \&main::PG_floating_point_exception_handler by
&Global::PG_floating_point_exception_handler

since the exception handler was moved under the package Global section of Global.pm
when the BEGIN block was moved in version 1.6

It's possible that  the floating point exception handler available for bad  answers
hasn't been working
properly for awhile.
