=head1 NAME
lonparmset - Handler to set parameters for assessments and course
=head1 SYNOPSIS
lonparmset provides an interface to setting content parameters in a
course.
It contains all the code for the "Content and Problem Settings" UI, except
for the helpers parameter.helper and resettimes.helper, and lonhelper.pm,
and lonblockingmenu.pm.
=head1 DESCRIPTION
This module sets coursewide and assessment parameters.
=head1 INTERNAL SUBROUTINES
=over
=item parmval()
Figure out a cascading parameter.
Inputs: $what - a parameter spec (incluse part info and name I.E. 0.weight)
$id - a bighash Id number
$def - the resource's default value 'stupid emacs
Returns: A list, the first item is the index into the remaining list of items of parm values that is the active one, the list consists of parm values at the 18 possible levels
18 - General Course
17 - Map or Folder level in course (recursive)
16 - Map or Folder level in course (non-recursive)
15 - resource default
14 - map default
13 - resource level in course
12 - General for section
11 - Map or Folder level for section (recursive)
10 - Map or Folder level for section (non-recursive)
9 - resource level in section
8 - General for group
7 - Map or Folder level for group (recursive)
6 - Map or Folder level for group (non-recursive)
5 - resource level in group
4 - General for specific student
3 - Map or Folder level for specific student (recursive)
2 - Map or Folder level for specific student (non-recursive)
1 - resource level for specific student
=item parmval_by_symb()
=item reset_caches()
=item cacheparmhash()
=item parmhash()
=item symbcache()
=item preset_defaults()
=item date_sanity_info()
=item storeparm()
Store a parameter by symb
Takes
- symb
- name of parameter
- level
- new value
- new type
- username
- userdomain
=item log_parmset()
=item storeparm_by_symb_inner()
=item valout()
Format a value for output.
Inputs: $value, $type, $editable
Returns: $value, formatted for output. If $type indicates it is a date,
localtime($value) is returned.
$editable will return an icon to click on
=item plink()
Produces a link anchor.
Inputs: $type,$dis,$value,$marker,$return,$call
Returns: scalar with html code for a link which will envoke the
javascript function 'pjump'.
=item page_js()
=item startpage()
=item print_row()
=item print_td()
=item check_other_groups()
=item parm_control_group()
=item extractResourceInformation() :
extractResourceInformation extracts lots of information about all of the the course's resources into a variety of hashes.
Input: See list below
=over 4
=item * B<env{'user.name'}> : Current username
=item * B<env{'user.domain'}> : Domain of current user.
=item * B<env{"request.course.fn"}> : Course
=back
Outputs: See list below:
=over 4
=item * B<ids> (out) : An array that will contain all of the ids in the course.
=item * B<typep>(out) : hash, id->type, where "type" contains the extension of the file, thus, I<problem exam quiz assess survey form>.
=item * B<keyp> (out) : hash, id->key list, will contain a comma separated list of the meta-data keys available for the given id
=item * B<allparms> (out) : hash, name of parameter->display value (what is the display value?)
=item * B<allparts> (out) : hash, part identification->text representation of part, where the text representation is "[Part $part]"

=item standardkeyorder()
=item assessparms() :
Show assessment data and parameters. This is a large routine that should
be simplified and shortened... someday.
Inputs: $r - the Apache request object.
Returns: nothing
Variables used (guessed by Jeremy):
=over
=item * B<pscat>: ParameterS CATegories? ends up a list of the types of parameters that exist, e.g., tol, weight, acc, opendate, duedate, answerdate, sig, maxtries, type.
=item * B<psprt>: ParameterS PaRTs? a list of the parts of a problem that we are displaying? Used to display only selected parts?
=item * B<@catmarker> contains list of all possible parameters including part #s
=item * B<$fullkeyp> contains the full part/id # for the extraction of proper parameters
=item * B<$tempkeyp> contains part 0 only (no ids - ie, subparts)
When storing information, store as part 0
When requesting information, request from full part
