Protect possible '=' and '&' in student answers.  Do this in DBglue8 as it is specific to the database used
rather than in processProblem8.

Revision 333 - Directory Listing
Modified Fri May 31 18:21:35 2002 UTC (17 years, 6 months ago) by apizer

Fixed bug reported by Danny Glin by removing all $ and @ from student answers before using them as sticky
answers.

Having much trouble with the exportation of functions from Complex1.

Maybe this will do it.

Fixed a misplaced  parens.

Revision 322 - Directory Listing
Modified Thu May 30 19:23:27 2002 UTC (17 years, 6 months ago) by gage

Commented out use PGtranslator.

This doesn't seem to have been actually used
and it's seems to be causing  an infinite loop with WWd.pm which
calls PGtranslator, which calls Global, which calls PGtranslator.
etc.

Revision 321 - Directory Listing
Modified Thu May 30 19:21:16 2002 UTC (17 years, 6 months ago) by gage

Fixed bug in PGcomplexmacros.pl having to do with the lack of a
=cut line in the pod documentation.

The loadMacros eval doesn't fail gracefully when this kind of mistake
occurs.  More work needs to be done on loadMacros.

Also changed the _PGcomplexmacros_init subroutine to include the
exporting of variables from Complex.

I think this is what it was supposed to do in any case, but perhaps not.
When using the forking process it was only necessary to export the
variables in the parent.

Revision 312 - Directory Listing
Modified Tue May 28 17:47:07 2002 UTC (17 years, 6 months ago) by apizer

 - changed reduce so that it would always leave the denominator
   positive (so reducing 6/-10 gives -3/5)
 - added documentation line for reduce
 - added method pow which takes an integer argument, and returns the
   fraction raised to that power (throwing warnings for indeterminant
   forms or division by 0)
 - added doc line for pow

Modified Fri May 24 15:54:55 2002 UTC (17 years, 6 months ago) by apizer

Corrected a minor typo in a comment. Mostly wanted to check how log messages appear. There was a problem with
the previous log message that was caused by terminal emulation on my PC.

Revision 219 - Directory Listing
Modified Mon Sep 24 16:52:17 2001 UTC (18 years, 2 months ago) by gage

Added documentation and _PG....macros_int functions to these files.

In PGcomplexmacros.pl I removed the automatic exportation of log() from
PGcomplexmacros.pl since
this (and sqrt() ) cause conflicts with CORE::log() and CORE::sqrt().
-- Warnings of the form "Ambiguous call to   ..... resolved in favor of
CORE::... " etc.

The functions can always be accessed by Complex::log() and Complex::sqrt()
when needed for complex numbers.

There may be a more sophisticated method of exporting these calls which
would avoid the warnings and remain transparent both to those who are
using complex numbers and those who are not.  If anyone has any ideas they
will be welcome.  The code to modify is at the top of the
PGcomplexmacros.pl file inside the _PGcomplexmacros_init subroutine.

the new code checks this formatting somewhat more rigorously and gives a

two changes. First the script no longer attempts to send mail to practice users
Secondly if it encounters a bad email address, it does not just quit as before
(without sending remaining messages) rather it goes on sending all messages
and at the end lists all students for whom no message was sent.

Revision 189 - Directory Listing
Modified Tue Sep 4 22:23:09 2001 UTC (18 years, 3 months ago) by gage

Added a change to loadMacros that allows for macro files that
end in .pg

Revision 188 - Directory Listing
Modified Tue Sep 4 16:40:58 2001 UTC (18 years, 3 months ago) by gage

Modifications in these two files make questions whose answer blanks hve
the same names behave properly.

The new versions of CGI seem to return such answers as a reference to an array.
Earlier versions returned the answrs as a string with \0 separators.

With the new changes the AnswerEvaluator get_student_answer subroutine and
the NAMED_ANS_RULE in PGbasicmacros.pl will handle either a null separated
string or an answer array when dealing with vector answers.

This should correct some difficulties experienced in the linear algebra
questions.  More testing needs to be done.

Revision 187 - Directory Listing

Revision 183 - Directory Listing
Modified Fri Aug 31 17:16:24 2001 UTC (18 years, 3 months ago) by sh002i

Cleaned these scripts up a little. Instead of setting the PATH, it just
uses the directory specified to call each utility with its full path. Also
added some documentation and got rid of some cruft (which, of course, one
can still pull out of CVS if needed). Incidentally, all the utilities used
in these two scripts are from the netpbm package.

Revision 182 - Directory Listing

Revision 180 - Directory Listing
Modified Fri Aug 31 16:43:08 2001 UTC (18 years, 3 months ago) by sh002i

Changed pdf generation process in welcomeAction.pl to use ghostscript

and added $Global::externalGsPath.

Revision 179 - Directory Listing
Modified Fri Aug 31 16:07:39 2001 UTC (18 years, 3 months ago) by sh002i

added $externalLaTeX2HTMLSupportPath to section about LaTeX2HTML stuff...

Revision 178 - Directory Listing
Modified Fri Aug 31 16:06:54 2001 UTC (18 years, 3 months ago) by sh002i

makeL2H now appends the contents of $Global::externalLaTeX2HTMLSupportPath
to $ENV{PATH} before calling latex2html. this is kinda hackish, but it
works. perhaps instead of this, we should set the path globally to
something like '/bin:/usr/bin:/usr/local/bin'. (see the email i'm about
to send.)

Revision 177 - Directory Listing

guess for the main directory when it asks the question.

Revision 173 - Directory Listing

Protect against possibility that {debug} is not defined
in AnswerEvaluator.

Revision 172 - Directory Listing
Modified Thu Aug 30 03:03:19 2001 UTC (18 years, 3 months ago) by gage

Made sure that num_cmp, fun_cmp and str_cmp return an
answer evaluator when used in scalar context.  In other words

$ans_eval = num_cmp(234);

will now work as expected -- you will get one answer evaluator which
checks whether the answer is 234.

Previously you had to write:

($ans_eval) = num_cmp(234);

or else you would have the numeral 1 placed in $ans_eval since
that is how many answer evaluators were created.

Added a default value for tolerance to is_zero_array
macro and removed the allow_unknown_defaults value.

Changed the call to is_zero_array from tol to tolerance in

tolerance value could not be set and was always being
set to a default value.

Revision 153 - Directory Listing
Modified Mon Aug 20 16:05:10 2001 UTC (18 years, 3 months ago) by apizer

Global::defaultReply.

Revision 143 - Directory Listing
Modified Thu Aug 16 21:21:13 2001 UTC (18 years, 3 months ago) by apizer

The webworkCourse.ph file now contains information on setting the
$smtpSender, defaultFrom and defaultReply variables

Revision 142 - Directory Listing

added this to the repository

Revision 141 - Directory Listing
Modified Thu Aug 16 20:07:49 2001 UTC (18 years, 3 months ago) by apizer

Two changes. One is to use Global::smtpSender for smtp
The other is to fill in a default from email address for the student

Revision 140 - Directory Listing

Revision 139 - Directory Listing
Modified Thu Aug 16 18:35:08 2001 UTC (18 years, 3 months ago) by sh002i

okay, actually commented out all the courseScripts lines this time.

Revision 138 - Directory Listing
Modified Thu Aug 16 18:32:17 2001 UTC (18 years, 3 months ago) by apizer

Revererted to profSendmail from system with bug fixes (see below).
The previous version incorporated Bill Wheelers initial checking of the
validity of email addresses.  However Bill has improved (or at least
changed) this a lot.  He has sent us a new version, but we do not have
time to check it out.  We will add the functionality later

Bug fixes, etc.  SMTP is now called with the address $smtpSender.  Default
values for headers now work

Revision 137 - Directory Listing
Modified Thu Aug 16 18:29:27 2001 UTC (18 years, 3 months ago) by sh002i

directory is no longer used).

Revision 136 - Directory Listing
Modified Wed Aug 15 15:03:08 2001 UTC (18 years, 3 months ago) by sh002i

Actually changed the value of $Global::externalLaTeX2HTMLInit. Sorry about
that. :P

Revision 135 - Directory Listing
Modified Wed Aug 15 14:45:38 2001 UTC (18 years, 3 months ago) by ch003i

Added 'allow_unknown_options' in is_a_zero_array filter to avoid error in function_cmp routine.

Unreferenced file -- removed.

Revision 131 - Directory Listing
Modified Tue Aug 14 20:25:40 2001 UTC (18 years, 3 months ago) by apizer

Modified lines 505-10 so that when a problem is viewed for the first time,
process_answers from PGtranslator.pm is still run with empty imput.  This
means that the correct mesages from problem graders will be displayed (and
erroneous error messages will not be displayed) the first time a problem
is viewed.

Revision 130 - Directory Listing
Modified Mon Aug 13 20:42:26 2001 UTC (18 years, 3 months ago) by sh002i

moved latex2html init files to lib.

Revision 129 - Directory Listing

Modified Mon Aug 13 20:29:42 2001 UTC (18 years, 3 months ago) by apizer

removed all reference to courseScripts directory (which is no longer used
by individual courses).  Also the default now in setting up a course is to
have the macros directory implemented.  Added comments on the
webworkCourse.ph file explaining how the macros directory works.

Revision 126 - Directory Listing
Modified Mon Aug 13 18:26:55 2001 UTC (18 years, 3 months ago) by sh002i

Moved from blankCourse, changed index.html from 0644 to 0664.

Revision 125 - Directory Listing

Updating pod documentation

Revision 124 - Directory Listing
Modified Mon Aug 13 16:09:14 2001 UTC (18 years, 3 months ago) by gage

Updating pod documentation

Revision 123 - Directory Listing
Modified Mon Aug 13 16:07:32 2001 UTC (18 years, 3 months ago) by gage

Removed warning message about avg_problem_grader, since now
avg_problem_grader is also installed in PGtranslator and can
be used as a default grader. (std_problem_grader can also be
used as a default).

Revision 122 - Directory Listing
Modified Sat Aug 11 03:17:43 2001 UTC (18 years, 3 months ago) by gage

More adjustments to documentation for answer evaluators

Revision 121 - Directory Listing
Modified Sat Aug 11 02:26:08 2001 UTC (18 years, 3 months ago) by gage

The pod documentation is now read from the mainDirectory as
defined in Global.

Revision 120 - Directory Listing
Modified Sat Aug 11 02:25:08 2001 UTC (18 years, 3 months ago) by gage

More documentation added.

Revision 119 - Directory Listing
Modified Sat Aug 11 01:48:05 2001 UTC (18 years, 3 months ago) by gage

Added pod comments to PGanswermacros for some of the filters.

I also rearranged the structure of the file slightly to make it
easier to add the pod documentation.

Revision 118 - Directory Listing
Modified Sat Aug 11 01:46:39 2001 UTC (18 years, 3 months ago) by gage

Added code to handle warning messages for the paperHeader.pg file
as well as the problems.

Made sure that the warning messages are protected for TeX ONLY when
the output will be hard copy (i.e. when the list @PG_COMPILE_ERRORS
is empty.) otherwise the warning messages are left as HTML

Revision 117 - Directory Listing
Modified Sat Aug 11 00:25:14 2001 UTC (18 years, 3 months ago) by gage

Added logPrint to error messages when the TeX code cannot be
converted into a .dvi file.  This allows useful feedback when
there is a pure tex error -- i.e. the .pg file compiles correctly
but the resulting TeX is not well formed.

Also added some code that adds warning messages after each problem (except
the screen/pageheader file) with some extra formatting so that messages
can be handled by the TeX processor.

If this latter code is adequate it should probably be abstracted and moved
to Global near where the PG warnings handler is defined. Currently the
code modifies the Global::WARNINGS variable VERY far away from the
definition of that variable.  It would be better to have a couple of
subroutines in Global that "print" the WARNINGS string, perhaps protecting
the characters that upset TeX, and another subroutine which clears the
WARNINGS variable.

Meantime keep testing the error output -- it's looking better.

Revision 116 - Directory Listing
Modified Fri Aug 10 19:29:56 2001 UTC (18 years, 3 months ago) by sh002i

> STRANGE BUG
fixed the strange bug!

Revision 115 - Directory Listing
Modified Fri Aug 10 19:03:37 2001 UTC (18 years, 3 months ago) by sh002i

Rewrote downloadAllSets to mak sense, fixed error reporting, fixed several
"used only once" warnings, enhanced filename handling for downloaded files
(this is very nice -- it can tell whether we're getting one set for
multiple students or multiple sets for one student :), changed temp file
naming scheme. what fun!

Revision 114 - Directory Listing
Modified Fri Aug 10 18:58:31 2001 UTC (18 years, 3 months ago) by ch003i

Edited l2h_sticky_answers to stop unwanted combining when answers used multiple fields.

No longer needed since welcomeAction.pl version 1.9

Revision 112 - Directory Listing
Modified Fri Aug 10 15:35:24 2001 UTC (18 years, 3 months ago) by sh002i

1. Fixed prepareHardcopy. Actually works now.
2. Incorporated old error reporting code into downloadAllSets
This file is incredibly hairy and should be cleaned up/split up a.s.a.p...

Revision 111 - Directory Listing
Modified Fri Aug 10 14:34:02 2001 UTC (18 years, 3 months ago) by sh002i

added variables for paths to hardcopy generation programs

Revision 110 - Directory Listing

set_default_options call.  Removed some warning messages.

Revision 109 - Directory Listing
Modified Thu Aug 9 21:37:29 2001 UTC (18 years, 4 months ago) by gage

AnswerEvaluators can now handle ans_hash as an input (this allows
the answerevaluator to be used as a filter in another answer evaluator

Cosmetic changes made to the error reporting when the debug
flag is set.

Revision 108 - Directory Listing
Modified Thu Aug 9 16:25:05 2001 UTC (18 years, 4 months ago) by ch003i

Edited check_eigenvector to include debug option and fixed post-filter to prevent crashing.

Revision 107 - Directory Listing
Modified Wed Aug 8 23:43:43 2001 UTC (18 years, 4 months ago) by gage

Made small corrections at lines 417 and 484 which were
causing compile time errors in /ww/logs/error_log.  (One
was redefining rh_flags subroutine, the other was an
uncommented fragment of a print statement.

Revision 106 - Directory Listing
Modified Wed Aug 8 16:26:11 2001 UTC (18 years, 4 months ago) by sh002i

This was an unreferenced copy of latex2html.init.96.1

Revision 105 - Directory Listing
Modified Wed Aug 8 16:17:10 2001 UTC (18 years, 4 months ago) by gage

Modified warning so that warnings when end in \n (or in ~~n for .pg files) do not have the extra
stack information appended.  This may sometimes make for cleaner output messages.

Revision 104 - Directory Listing
Modified Wed Aug 8 15:29:51 2001 UTC (18 years, 4 months ago) by gage

Made sure that the error handlers have Global:: prefixes

Revision 103 - Directory Listing
Modified Wed Aug 8 02:29:05 2001 UTC (18 years, 4 months ago) by gage

Changed names in calculate difference vector   subroutine to make the
process a bit clearer.  There is still more work to be done.

Revision 102 - Directory Listing
Modified Wed Aug 8 02:24:16 2001 UTC (18 years, 4 months ago) by gage

Minor  changes to the #!/usr/bin/perl line

Revision 101 - Directory Listing
Modified Wed Aug 8 02:17:35 2001 UTC (18 years, 4 months ago) by gage

Changed package name  for error handlers to Global:: (from main::) to match
the change which occured in Global.pm version 1.6 where the handlers were moved
inside the Global.pm package.
	 $SIG{'FPE'}  = \&Global::PG_floating_point_exception_handler;
	 $SIG{__WARN__}=\&Global::PG_warnings_handler;

Warning messages from within problems and from within macros should now work again.

Revision 100 - Directory Listing
Modified Wed Aug 8 02:13:25 2001 UTC (18 years, 4 months ago) by gage

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.

Revision 99 - Directory Listing

need to me mangled!

Revision 93 - Directory Listing
Modified Tue Aug 7 16:11:09 2001 UTC (18 years, 4 months ago) by sam

Added index.html file as a placeholder for removed docs. This allows
browser requests for the directory to yield a useful error message rather
than "FORBIDDEN"

Revision 92 - Directory Listing
Modified Tue Aug 7 16:05:31 2001 UTC (18 years, 4 months ago) by sam

1. Set all "WeBWorK docs" links to http://webwork.math.rochester.edu

This might break problems involving matrices or ones involving
answering questions with arbitrary constants (e.g. indefinite integral)

I believe I have caught all of the instances in which this name is used.

Replaced $piece1 with $piece3 in line 336 and following to avoid a
"my" conflict.  I also commented out oldivy which contained a print

Split evalutesToNumber into subroutine is_a_numeric_expression.  No changes in functionality.

Revision 49 - Directory Listing
Modified Thu Jun 21 19:53:59 2001 UTC (18 years, 5 months ago) by chris

Added "evaluatesToNumber" subroutine.  In conjunction with fix_answer_for_display filter, this now fixes a bug with displaying student_ans in a problem that allows strings for valid answers.

Revision 48 - Directory Listing
Modified Thu Jun 21 19:45:24 2001 UTC (18 years, 5 months ago) by sam

Added system_webwork_setup functionality to ask for the group under which
the webserver runs and chgrp the logs/ directory to that group. Thus,
logfiles have been taken out of cvs, and only the directory remains. You
can add the line
	$serverGroupName = "webwork";
to your system_webwork_setup.defaults file if you like.

Revision 47 - Directory Listing
Modified Thu Jun 21 19:02:29 2001 UTC (18 years, 5 months ago) by chris

Same as PG163macros.pl with a new name.  subroutine ivy updated to improve readability.

Revision 46 - Directory Listing
Modified Thu Jun 21 19:00:53 2001 UTC (18 years, 5 months ago) by amanda

Revision 45 - Directory Listing
Modified Thu Jun 21 16:58:25 2001 UTC (18 years, 5 months ago) by gage

Added PGcomplexmacros.pl and PGmatrixmacros.pl to CVS

Revision 44 - Directory Listing

Revision 40 - Directory Listing
Modified Thu Jun 21 13:33:27 2001 UTC (18 years, 5 months ago) by gage

Changed NUM_CMP so that the calculated versions of the student's answer
and the professor's remain in the answer hash to be displayed by
displayMacros.

There are now slight clues, when using num_str_cmp that the
instructor's answer is a string. I'm not sure anyone can find them
easily.  Further refinements should be able to remove them in any case.

Revision 39 - Directory Listing
Modified Thu Jun 21 10:21:28 2001 UTC (18 years, 5 months ago) by maria

added inv_romberg function which, given a function, a, and value computes b s.t. integral from a to b is equal
to value.

Hints and Solutions now use basically the same mechanism.  Fixed hugs in hints
and minor bugs in solutions.

Revision 36 - Directory Listing
Modified Wed Jun 20 20:01:26 2001 UTC (18 years, 5 months ago) by gage

Simplified some of the scripts.  Using forking there is no need
to evaluate $main:: everytime, since it remains the same for both
the parent (where the script is compiled) and in the child where
the script is executed.

There were other minor fixes to work around bugs in 5.6.0 which were
fixed in 5.6.1

Revision 35 - Directory Listing
Modified Wed Jun 20 19:04:08 2001 UTC (18 years, 5 months ago) by chris

Modified num_cmp to use filters for string comparsions.  Routed std_num_str_cmp through num_cmp routines.

way it is called from dangerousMacros.pl

Revision 29 - Directory Listing
Modified Tue Jun 19 21:56:35 2001 UTC (18 years, 5 months ago) by gage

Fixed an evaluation which was being done at compile time rather than at
run time.  This could cause the definition of 'main' to be incorrect.

The evaluation was in an error message, so it has probably not been noticed.

Revision 28 - Directory Listing
Modified Tue Jun 19 20:56:08 2001 UTC (18 years, 5 months ago) by gage

Fixed problem in dangerousMacros.pl defining i so that it can be used
as a complex number.

Fixed htmlLink so that it gives a friendly error message about broken links
when fed an undefined url.

Revision 27 - Directory Listing
Modified Tue Jun 19 20:31:39 2001 UTC (18 years, 5 months ago) by gage

Many modifications to courseScript scripts which will insure that the
routines are re-entrant (i.e. they can be called via mod_perl and don't
need to be re-compiled for every execution run.)

Minor modifications to processProblem8.pl and to PGtranslator.pm

Modified Tue Jun 19 13:07:28 2001 UTC (18 years, 5 months ago) by chris

Revision 21 - Directory Listing
Modified Tue Jun 19 12:14:14 2001 UTC (18 years, 5 months ago) by apizer

Added code giving students the choice whether or not to "show my old
answers", i.e. to show storred sticky answers.  The default for practice users
and all users after the answer date is not to show these.  Otherwise the
default is to show them.  This required a change everywhere processProblem
is called.
