BEGIN-block method for library inclusion to command-line scripts.

Revision 68 - Directory Listing

Revision 65 - Directory Listing
Modified Sun Jun 24 03:55:24 2001 UTC (18 years, 5 months ago) by gage
Replaced $piece1 with $piece3 in line 336 and following to avoid a
"my" conflict.  I also commented out oldivy which contained a print
statement and therefore wouldn't compile within the problems.

These are temporary fixes, for this file in order to enable it to compile.

Modified Fri Jun 22 21:29:58 2001 UTC (18 years, 5 months ago) by gage
Fixed errors in sourceAlias

Modified parts of alias so that PG_restricted_eval was not used.
(This is unnecessary as long as we use forking to create a child
with the same namespace.)

Revision 60 - Directory Listing

Added _PGgraphmacros_init subroutine

Revision 50 - Directory Listing
Modified Thu Jun 21 20:38:56 2001 UTC (18 years, 5 months ago) by chris
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

fixed fact and step functions so they are recognizable functions again.i

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
Modified Thu Jun 21 15:38:33 2001 UTC (18 years, 5 months ago) by chris
Corrected "unrecognizable units" error message so it is displayed correctly.

Revision 43 - Directory Listing
Modified Thu Jun 21 15:00:33 2001 UTC (18 years, 5 months ago) by maria
fixed inv_romberg

Revision 42 - Directory Listing
Modified Thu Jun 21 14:57:19 2001 UTC (18 years, 5 months ago) by maria
new macros

Revision 41 - Directory Listing
Modified Thu Jun 21 14:40:51 2001 UTC (18 years, 5 months ago) by chris
Added postfilter fix_answers_for_display which incorporates all changes made in previous version.

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.

added back the fact (factorial) function that has been accidentally deleted

Revision 37 - Directory Listing
Modified Thu Jun 21 01:03:14 2001 UTC (18 years, 5 months ago) by apizer
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.

Revision 34 - Directory Listing
Modified Wed Jun 20 02:02:49 2001 UTC (18 years, 5 months ago) by gage
Fixed problem in std_num_cmp arising from an earlier merge.

Revision 33 - Directory Listing

Corrected error in _PGanswermacros_init

Revision 32 - Directory Listing
Modified Wed Jun 20 00:32:01 2001 UTC (18 years, 5 months ago) by gage
Added _PGanswermacros_init subroutine

Revision 31 - Directory Listing

.

Revision 30 - Directory Listing
Modified Tue Jun 19 22:29:01 2001 UTC (18 years, 5 months ago) by gage
More refinement of the initialization routines in PGbasicmacros.pl and the
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

Revision 26 - Directory Listing
Modified Tue Jun 19 16:49:09 2001 UTC (18 years, 5 months ago) by gage

Revision 22 - Directory Listing
Modified Tue Jun 19 13:07:28 2001 UTC (18 years, 5 months ago) by chris
Added unix-style filters to NUM_CMP and re-routed all numerical answer evaluators to num_cmp.  Combined numerical_compare_with_units and NUM_CMP.

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.

Modified Tue Jun 19 01:50:35 2001 UTC (18 years, 5 months ago) by gage
