Altered course in how to set vertical alignment of images, so this
undoes calls for javascript, and passes more arguments to imagegenerator
(which can be used someday soon).

Allow students to check answers between the due date and the answer date. This doesn't let them see the correct answers, but it does let them enter values to see if those are right without recording them.

Make sure that if one message is reported for answers then all
messages are reported (even if some of the messages are blank).
This was clearly a typo in the original code where a decision was
made on $answerMessages instead of $showAnswers.
This fixes bug #370

Normalized headers. All files now contain the text below as a header.
This is important since all files now (a) use the full name of the
package, (b) assign copyright to "The WeBWorK Project", (c) give the
full path of the file (relative to CVSROOT) instead of simply the file
name, and (d) include license and warranty information.
Here is the new header:

Fixed problem in logic which kept an edited problem from reading the
.tmp file when the answer was submitted. Now the editMode variable
and sourceFilePath variables are passed on as hidden variables by
Problem.pm if they exists in the input form. This fixes bug #179
as well as bug #109.
The temporary file is now labeled fileName.pg.user.tmp where user is
the login name of the person editing the file. If that file exists
then pgProblemEditor will attempt to use that as a source file.
The revert button forces a read from fileName.pg

Fixes bug #254. The showHints check box will not be shown unless
the number of incorrect attempts is greater than or equal to the
value of showHints.
The showHints checkbox now appears in red (and in a new <div> which
means a new paragraph on some browsers) This helps alert a student that
a hint is now available.

When recording answers the answer strings are now obtained directly from the original
formField entries, rather than from the processed version in the answer hashes.
This insures that the memorized answers will be identical with the ones that would
have been submitted from the form.
This is important for answers with multiple values which are represented by
null separated strings. The answer evaluation process converts these strings
to references to arrays, and -- in order to have good display properties -- the
original_student_answer slot in the AnswerHash contains a representation such as
( 4, 5, 6).
This is NOT suitable for resubmitting as an answer in a form field and is therefore not the
right thing to store in the data base when saving answers.

Changed logic of what is shown about answers when
"submit Answers" and "check Answers" are clicked.
In particular you can't see the answers responses at
all unless one of these two or "preview answers" is cliced.
Hopefully this will not upset preflight uses.

Removed some hidden inputs from the main form that were making it
impossible to uncheck "show correct answers" (and probably doing

think it is more appropriate. Particularly

cleaned up mike's editor support functionality. it now stores the source
file override and seed override in the $problem object. this eliminates
special logic further down the line. (eventually, i would like to have a
separate frontend to PG for the editor, like Instructor::PGPreview.pm)

I believe this is is the root cause of the multiple key parameters. I
haven't done all of the testing needed to verify this for sure.
Bug #50 is probably comotose, but needs to be watched.

replaced $r->param('key') with my $key = $r->param('key'); and then used $key in call
to PG. $r->param('key') was returning a two item list in list context. I don't know
where the extra entry into the key param was coming from.
This stuns bug #50, but doesn't kill it.

Added a section to handle the case where the problem has not yet been
assigned to a user. This might occur when the problem template is
called form the problem editor before the sets have been assigned
to students. The problem is obtained as a global problem
then converted to a user_problem with default values. The problem
is not saved. This code should be reviewed to make sure there are no
hidden behaviors. Perhaps a group reading is in order once things
settle down. This squashes bug #34.

Made small modifications to allow Problem.pm to read a problem that has
not yet been assigned.
TO DO (and I'll need help with this)
Convert a global set to a global user set (and the global problem to a
global user problem). I need to know how to specify the appropriate
classes.
Once we are guaranteed a record of the type returned by getGlobalUser
....
stuff missing defaults (e.g. psvn for set, and num_correct (answers) for
problem) in the newly created global_user record objects.(this part I
can do.)
At that point the rest of Problem.pm should be able to proceed as before
without any changes.

Display options are now sticky (they are repeated as hidden options in the main problem body).
Changed name of submit button from redisplay to "save options"
fixes bug #27 at least to some extent.
these saved options may not persist from one problem to another. In order to solve that problem
we need a storage place for user options, or else many more hidden inputs to save state as one
moves from one request to another.
this fix will work for now.

Modified viewOptions to conform to a "vertical" look for the radio buttons in the redisplay options.
Modified some of the labels for the same reason.
The horizontal spacing is a bit of kludge (I can't guarantee no line breaks for each of the radio button
labels). Using underbars instead of spaces in the labels would fix this, but...

Problem Editor now creates a temporary file to edit (
adding .tmp to the file name)
Refresh causes a redirect to the Problem.pm with a GET command.
Some of the arguments are unnecessary and need to be cleaned up.
The seed and display mode in the problem editor are not properly
initialized from the problem set.
Problem.pm has been modified to check for these arguments and to read
the temporary source file, seed and displayMode. These are passed
through to a PG.pm object.
PG also needed to be modified so that the source_file and seed values
are overridden.

DONE effectiveUser for at least Problem.pm
DONE write a template escape for printing $user, $effectiveUser, &c. nicely
also added additional timing log points: timing is now logged:
1. when WeBWorK::PG::new starts
2. after all the initialization-type stuff happens
3. when WeBWorK::PG::new ends
Getting it to log the entire request time might be a little harder.

- created macros/IO.pl, which is loaded with no opmask by PG.pm. It is a copy
of WeBWorK::PG::IO.pm, with some changes to make it work as a macro package.
The translator no longer shares IO.pm's functions with the safe compartment.
This is a BAD THING, and should be reconsidered when the Translator is
revised.
- Changed many (but not all) checks for HTML or HTML_tth modes to match /^HTML/
in the macros.
- changed &header to &head in Problem.pm
- Added problem environment variables for gif2eps and png2eps and modified
&dangerousMacros::alias to use them
- fixed MOST of the harmless warnings in the system. there's still the "Use
of uninitialized value in null operation" warning in template(), tho.
Still to come:
- make images in PDFs work
- fix TTH mode character encodings on mac (maybe)
- have logout button invalidate key
- Pretty die messages (from outside of the translator)
- Feedback - need nice modular way of sending email
- Options - email address and password

5. use - standard perl modules
6. use - CPAN modules
7. use - webwork modules
- ALWAYS use strict and use warnings
- use "use base" rather than "our @ISA"
so now we can be happy.

added refreshMath2img to the problem environment (PG.pm) and modified
Problem.pm to set it when showHints or showSolutions is on. THIS IS NOT
THE BEST THING TO DO -- we only need to refresh when the value of
showHints or showSolutions CHANGES. Also, we should be refreshing if the
problem seed changes. So, we need somewhere to store those three values
between invocations of the script. HHHHHMMMMMMMM......... &math2img in
dangerousMacros.pl has been modified to respect refreshMath2img and also
refresh if the image file is older than the PG source file.

Some edits to make it work on my system, and some code cleanups. You'll
probably have to edit it on the top (right now) to get it to work on your
system. /this will change/ in the future. But it's nice to have a working
demo.

Problem.pm now works (kindof) to serve PG problems. There are configuration
variables at the top that have to be customized to an individuals directory.
(They could be placed in a config file to avoid having to update them constantly,
but soon these values should be set by information from the course and
problem environments.)
The code is still rather delicate. It seems to work with some problems and not
with others. I suspect that the macro files are not being properly read in
and that perhaps the warning mechanisms are not yet working properly.
Also beware the line ending problem. Some of these files were created on a
mac (using unix). I've had completely mysterious errors that were fixed
by checking the line endings.
There is also a lot of code, particulary the error reporting code which should be put
in its own module.

I've added code for defining the problemEnvironment, at least for now.
Many of the values which will be pulled from the database have simply
been hardcoded into the subroutine.
There is also code to pretty print these values to aid in debugging.
