Sticky Revision:
Revision 1506 - Directory Listing
Modified Fri Sep 19 01:30:13 2003 UTC (16 years, 2 months ago) by gage 
Fixed check_string filter so that it places a
value in preivew_text_string and in preview_latex_string
in the answer hash.  For example entering DNE did not
show up in answer preview, which bothered some students.

Modified Mon Sep 15 05:47:38 2003 UTC (16 years, 3 months ago) by lr003k 
It seems as though the way I tried to fix long decimals isn't working the way I wanted it too, so I've commented it out for now.

Revision 1494 - Directory Listing
Modified Tue Sep 9 02:06:31 2003 UTC (16 years, 3 months ago) by jj 
Put mbox around entries of a matrix in TeX-based modes to protect
math inside of them.

Changes to mail that make it work properly with ALLOW_MAIL_TO
--Mike
Revision 1462 - Directory Listing
Modified Fri Aug 15 16:49:42 2003 UTC (16 years, 4 months ago) by gage 
Made changes to rh_sticky_answers so that they
are addressed correctly.

Long term I would like to remove all
references to main:: except for those
in the init routines.  The references
can be replaced by a locally defined
pointer to the  value in the current safe
compartment.

This procedure should make it easier to
maintain the macros.  All references to
global variables will occur in the init
routine.

--Mike
Revision 1456 - Directory Listing
Modified Thu Aug 14 16:10:01 2003 UTC (16 years, 4 months ago) by gage 
At least a temporary fix for mail_answers_to2

These evaluators are run in the grader and the
environment variables have disappeared??  I can't find
them at any rate.

this is at best a temporary fix until we get the global
variable situation under control when using cached code.
--Mike
Revision 1455 - Directory Listing
Modified Thu Aug 14 13:27:54 2003 UTC (16 years, 4 months ago) by gage 
Made changes to anstext and a few
other answer evaluators so that they
evaluated "main::" correctly.

Still need to fix install problem

involved removing unwanted spaces, etc.

Revision 1365 - Directory Listing
Modified Fri Jul 11 20:18:57 2003 UTC (16 years, 5 months ago) by lr003k 
In order to make ans_array entries "sticky" I've had to change some stuff.
The answer labels for these entries are now put into $main::PG_FLAGS{ANSWER_ENTRY_ORDER} as an array reference in PG.pl.
In processProblem8.pl the labels are caught again in the subroutines logCourseData and encode_submitted_answers. It is important that
they're caught there rather than earlier because then the translator would think that every entry was it's own answer.
Professor Gage says that processProblem8.pl is no longer used in webwork2, and he says he'll fix this there.
Revision 1351 - Directory Listing
Modified Fri Jul 11 16:30:04 2003 UTC (16 years, 5 months ago) by apizer

Revision 1328 - Directory Listing
Modified Wed Jul 9 19:45:40 2003 UTC (16 years, 5 months ago) by gage 
Added $ to PG_random_generator in the subroutine SRAND.  Why it worked
before as a bare word is anyone's guess. Now that $PG_random_generator
is a local variable the bareword no longer works properly.

--Mike
Revision 1294 - Directory Listing
Modified Fri Jun 27 13:57:09 2003 UTC (16 years, 5 months ago) by lr003k 
Added a vec_solution_cmp. Used for problems where the answer
needs to be v1_s*v2+t*v3 where v1,v2,and v3 are vectors. v1 has
to be a linear combination of the professors answer where the
first one has a nonzero coefficient. The others are a basis, and
are compared with compare_basis.
Revision 1286 - Directory Listing
Modified Thu Jun 26 21:08:47 2003 UTC (16 years, 5 months ago) by gage 
Make sure that the local my variables are updated in PGbasicmacros

Revision 1250 - Directory Listing
Modified Mon Jun 23 15:43:11 2003 UTC (16 years, 5 months ago) by gage 
Made changes required to allow caching of these files.
My tests indicate that these changes are compatible with webwork1.8
One possible problem might be the mail-to answer macros
which access the environement variable directly
I think I have this properly patched, but it has not been
tested yet.
--Mike
Revision 1238 - Directory Listing
Modified Fri Jun 20 19:05:38 2003 UTC (16 years, 5 months ago) by lr003k 
Matrices now take math constants.
Revision 1237 - Directory Listing
Modified Fri Jun 20 18:59:44 2003 UTC (16 years, 5 months ago) by lr003k 
Student answer now displayed in a html table given by jones's
display matrix method in PGmatrixmacros. The braces were giving
me headaches so I set the option to none, at least for now.
Revision 1161 - Directory Listing
Modified Fri Jun 13 17:36:10 2003 UTC (16 years, 6 months ago) by lr003k 
Was not accepting negative answers, the sign problem is fixed now.
Revision 1158 - Directory Listing
Modified Fri Jun 13 17:12:18 2003 UTC (16 years, 6 months ago) by sh002i 
rollback change to the way ImageGenerator::add is called.

Revision 1140 - Directory Listing
Modified Thu Jun 12 19:14:38 2003 UTC (16 years, 6 months ago) by gage 
Answer labels are now prefixed by a Quiz prefix which allows more
than one problem to appear on the same page.

Revision 1127 - Directory Listing
Modified Wed Jun 11 19:18:19 2003 UTC (16 years, 6 months ago) by lr003k 
Was working from an older copy before my last update, sorry.
Revision 1126 - Directory Listing
Modified Wed Jun 11 18:34:40 2003 UTC (16 years, 6 months ago) by jj 
Fixed isPrime, which had said that 4 was prime, and shortened its loop.
Revision 1123 - Directory Listing
Modified Wed Jun 11 15:28:47 2003 UTC (16 years, 6 months ago) by lr003k 
Ok, there is the ans_array_filter added which allows for the answer to be coming from the ans_array.
Revision 1122 - Directory Listing
Modified Wed Jun 11 14:54:27 2003 UTC (16 years, 6 months ago) by lr003k 
Added two methods for naming the blanks in ans_array. The names now have the format ArRaY3[1,0,2] (this would be the name of
the 3rd answer (it's taken from main::answer_count which is then incremented so the answer before it is AnSwEr2 and the
answer after it is AnSwEr4) and it would be the second matrix or vector in the answer ( I need to take multiple vectors for
things like basis cmp, so ans_array_extension puts the vectors in different locations) and the 0 and 2 are row and column in
that matrix or vector.
Revision 1121 - Directory Listing
Modified Wed Jun 11 14:47:59 2003 UTC (16 years, 6 months ago) by lr003k 
I removed the subroutine answer_matrix since it really belongs in basic macros with the other answer blank methods.
Revision 1120 - Directory Listing
Modified Wed Jun 11 14:46:35 2003 UTC (16 years, 6 months ago) by lr003k 
I've added ans_array and ans_array extension and moved answer_matrix here since this is probably where it should be with all
the other answer blank methods. I still have to comment the code.
Revision 1115 - Directory Listing
Modified Wed Jun 11 02:43:42 2003 UTC (16 years, 6 months ago) by apizer 
Fixed error concerning variable $string.
Cleaned up how polynomials are displayed.

Revision 1102 - Directory Listing
Modified Tue Jun 10 16:23:47 2003 UTC (16 years, 6 months ago) by lr003k 
ok, I'm pretty sure that this one is the one we want. Unfortunately the other one was an old one, that cmpl_cmp4 was not used
anywhere and I had removed it later, and this one has multi_cmp. Sorry for all the confusion.
Revision 1097 - Directory Listing
Modified Mon Jun 9 23:26:19 2003 UTC (16 years, 6 months ago) by jj 
Slightly better handling of top_labels in tth mode when force_tex is set; namely
it ignores the labels instead of letting the TeX code confuse tth so badly that
the matrix is basically lost.
Revision 1091 - Directory Listing
Modified Mon Jun 9 21:53:11 2003 UTC (16 years, 6 months ago) by gage 
Added > /dev/null tags to the commands which run tex and dvi for
HTML_img mode.  These will probably work now for the most part.
I don't know how well this will work if there is an error in
getting either tex or dvips to run.

For many problems using WeBWorK1.8 and typeset3 mode  thing work fine.
Please submit example problems where the images don't show up or some
other image related error occurs as bugs to
