openwebwork-devel — WeBWorK development discussion

[WWdevel] help please

[Ever B. <wv...@gm...>]

I am an engineering professor using and converting faculty here to use
Webwork. I am not a CS prof. but I have decent programming skills (Python,
ASP, C#, HTML, CSS, Javascript..., no PHP though) I downloaded and
installed Webwork from the source into my own Ubuntu/Apache2 web server
from where we run our courses. I want to make some local mods to make
Webwork friendlier to the culture here at West Virginia University, minor
things that cannot be done by tweaking the UI as is. I just want to work on
Webwork2 which I understand it is the Web interface. Right now I see a
bunch of folders and no idea where to start. If you could just get me
started, what languages are used, where are things located, I can learn
what I need. Thank you.

Hi,

Would you be interested in buying/owning the domain name openwebwork.com so
you can redirect it to your website?

Re: [WWdevel] Adding a question editor and equation editor

[Djun K. <dju...@st...>]

Hi Jean-Philippe,

There is quite a lot of work going on in the area of problem editors and visual equation input - we welcome your energy and contributions.

There's been a sequence of code camps over the past year to enable developers to get together to plan and implement improvements to WeBWorK.  The next one (coming up very soon) is to focus on the problem editor and library management.

Have a look at the forums and wiki (at webwork.maa.org), the mailing list archive, and the various openwebwork github projects.

Warmest regards, 

Djun

All right, I'll dig deeper into that.

[WWdevel] Equation editor

[Jean-Philippe G. <jea...@gm...>]

Just to mention that the sourceforge projet JQuery MathView have been
created to hold the mathematical expression editor. The first commit to be
done soon.

[WWdevel] Adding a question editor and equation editor

[Jean-Philippe G. <jea...@gm...>]

Hi,

I'm currently working on a projet for the french colleges of Canada that
aims to add french support for WeBWorK. We are in contact with Sébastien
Labbé from UQAM (through Louise Pellerin) who already work in that
direction. The project has many goals and somes are outside of the french
translation which are :

1) Create Maple T.A. to WeBWork questions translator helper (
http://sf.net/projects/mta2ww/)
2) Add a more user friendly question editor to WeBWork (inspired from Maple
T.A.)
3) Add an online visual euqation editor using JQuery/MathJax/MathTex

All of the above being developped under GPL, some as stand alone
sourceforge projects and other direcly into the WeBWork code.

I write to this mail list to insure that we don't overlap with other people
work and to get feedback about what we do. If you have any question, advice
or comments please get in touch with us.

Sincerely,

Jean-Philippe Gravel, P. Eng., CSDP

True enough -- I think the original rational was that the active .css file is directly accessible from the web while the system.template file is not.
So template.system was in the conf directory, while the css file had to be under webwork2/htdocs   or else linked to something in there.
The original rational again was that anything webaccessible had to go through either webwork2/htdocs   or  course/html   -- it was a very 
primitive form of taint checking.  

I'm open to other suggestions for organization -- although we will also have to deal with the migration issue if we come up with a better idea.

The svn docs are  at  -- http://wwrk.maa.org/wiki/Subversion

Email  Jason Aubrey <au...@ma...>  for permission to commit to the svn.  We were thinking that you might like to 
keep some of your more stable development in something like 

......svn/system/branches/djun_project/webwork2

and coordinate with us about when and if to merge that code into the main development trunk.

My son David (a recent CS graduate) introduced me to jQuery -- he just programmed a graphicsInput device in html5 using 
jQuery a little and processing.js  a good deal more.  

A prototype is at 
https://hosted2.webwork.rochester.edu/webwork2/dgage_course/graphInput/4/  (you can login as guest)

I have to do some more work to connect it up to some sample problems.  It looks like HTML5 will be a lot lighter weight than either 
the java applets or the flash applets we have been using earlier.

Talk to you later.

Take care,

Mike

[WWdevel] Introduction

[Djun K. <dju...@ma...>]

Hi All 

     I'm interested in doing some development on WeBWorK. 
I wanted to introduce myself and get some sense for what
activity is currently happening with the project.

     Cheers, Djun

Hi John,

try it again and see if it works for you this time.

thanks for helping to debug.

Re: [WWdevel] National Problem Library repository

[John J. <jj...@as...>]

I just ran the checkout command below, and the ".pg" files are ".pg,v".  
So, file names are slightly different, and they contain versioning 
information in them.

Re: [WWdevel] Behavior of Hmwk Sets Editor

[Michael G. <ga...@ma...>]

Hi Gavin,

The main reason for the "edit selected sets" mode was so that you  
could edit the dates
(the most common change) for several sets at once using copy paste, etc.

My suggestion would be to modify the page you reach with "edit  
selected sets"
by adding a link to the page where you could edit the all of the data  
for that set.

Would that help?

I personally find the hint about how many problems are in a set  
useful -- it alerts me to bogus homework sets (no problems)
and sometimes even to problems with real homework sets ("I thought I  
assigned more problems than that ....")

My 2 cents.

Take care,

Mike

[WWdevel] National Problem Library

[Michael G. <ga...@ma...>]

Hi,


The problems in  the ucsb_problib  repository are not tagged.

I think they should be tagged before we move them  into the  
NationalProblemLibrary tree.

How should we organize this?

take care,

Mike

[WWdevel] National Problem Library repository

[Michael G. <ga...@ma...>]

Hi,

I have created a new National Problem Library (and copied the old one  
into it).

It is at

cvs -d:ext:you...@cv...:/webwork/cvs/npl  co  
NationalProblemLibrary


check that you can download from this repository (and commit to it)

Once I'm sure this is functioning I will make the    /webwork/cvs/ 
asu   database_problib   directory
read only.

I have changed the directions for downloading the  
NationalProblemLibrary on the wiki at

http://webwork.maa.org/wiki/National_Problem_Library

Arnie -- would you change the directions on your install applications  
as well?

Davide -- could you make sure that the    /webwork/cvs/npl/ 
NationalProblemLibrary/Union   tree is up to date?
Once it is I will make the other repositories read only as well.

I have already made   rochester_problib,  tcnj_problib   and other  
repositories which had been moved under database_problib
read only.

Let me know if something isn't working.

Take care,

Mike

[WWdevel] Behavior of Hmwk Sets Editor

[P. G. L. <gl...@um...>]

Hi all,

Currently the homework sets editor page provides, among other things, the 
option to "Edit selected sets," and lists sets in a table with columns
   Select		- [select checkbox]
   Edit Set Data		- SetName (link to edit set visibility and dates)
   Edit Problems		- # (link to set detail page)
   Edit Assigned Users	- #/# (link to edit assigned users page)
   Visible		- Yes|No
   Open Date		- MM/DD/YY at TT:TT
   Due Date		- MM/DD/YY at TT:TT
   Answer Date		- MM/DD/YY at TT:TT

Clicking "Edit selected sets" or the "Edit set data" link goes to the 
"Hmwk Sets Editor" edit page that allows editing of visibility, open, due 
and answer dates.  From there one can go to "Edit All Set Data" on the set 
detail page.

Clicking "Edit problems" goes directly to the set detail page, where all 
aspects of the set can be edited.

This is semi-intuitive, in that "editing set data/selected sets" allows 
one to edit most of the data appearing in the table.  But it's also 
non-intuitive, in that clicking "Edit set data" or "Edit selected sets" 
doesn't actually take one to the full set editing page.

Questions:
1. Is this the behavior we want on this page?

2. Would it be more intuitive to change the table to have columns
   Select			- [select checkbox]
   Edit Set Data and Problems	- SetName (link to set detail page)
   Edit Assigned Users 		- #/# (link to edit assigned users page)
   Visible			- Yes|No
   Open Date			- MM/DD/YY at TT:TT (link to edit dates)
   Due Date  			- (similar)
   Answer Date			- (similar)
(where "link to edit dates" goes to the "Hmwk Sets Editor" edit page 
allowing editing of visibility and dates).

The only disadvantage I can see to option (2) is that it loses the 
information about the number of problems in the set.  So another option 
would be

2a. Have columns
   Select                        - [select checkbox]
   Edit Set Data and Problems    - SetName (link to set detail page)
   Number of Problems		- #
   Edit Assigned Users           - #/# (link to edit assigned users page)
   Visible                       - Yes|No
   Open Date                     - MM/DD/YY at TT:TT (link to edit dates)
   Due Date                      - (similar)
   Answer Date                   - (similar)

Danny Glin (U Calgary) pointed out that the behavior of the page is not 
entirely intuitive, so I thought I'd push this out to a larger list of 
people to comment.  Please respond if you have any opinion.

Thanks,
Gavin

That might be the case, but I don't remember.  That would be bad,  
since main:: contains LOTS of functions.

I think PGcommonFunctions.pl would be the one to remove, as it is not  
called directly from any problem files, but only from  
PGauxiliaryFunctions.pl and Parser.pl (or maybe it's Value.pl; I  
don't remember).

Note that the dozen or so other functions are not ones that usually  
make sense for use in student answers, which is one of the reasons  
that they are not available in MathObjects.  But it would not be a  
problem if they were moved to PGcommonFunctions.pl either as direct  
definitions, or as the kind that use CommonFunctions->Call so that  
they COULD be hooked into MathObjects if desired.

All the ones in commonFunctions.pl are in MathObjects contexts.  You  
could list which ones are in which contexts, I guess.  The ones in  
PGauxiliaryFunctions.pl are NOT in any MathObject context.

Remember that is is always possible to add new functions to a context  
(and to copy them from one context to another on the fly).

Re: [WWdevel] [WWcvs] pg: fixed typo by changing all references to IntegerFunction or IntegerFunctions to the plural The typo gave an immediate error

[Michael G. <ga...@ma...>]

I think I've got it :-).  Thanks.

The PGauxiliaryfunctions.pl  and PGcommonFunctions.pl  define perl  
functions not MathObject functions.
Instructors can use perl functions such as $a = C(15,3)
  but $A = Compute("C(15,3)"); will produce an error and students will
not be able to use C(15,3) as part of their answer.  This all seems  
like the correct behavior to me.

(I believe this is a minor change from the behavior of fun_cmp before  
MathObjects since, to the best of my recollection,
the perl parser for fun_cmp had access to any function defined in a  
main::  by PGauxiliaryfunctions.pl  ) The current situation is  
preferable I just
need to make sure I understand it well enough to document it accurately.

For the next step:  My first impression is that we can add the dozen  
or so remaining functions in PGauxiliaryfunctions.pl to  
PGcommonFunctions.pl and eliminate or redirect the first file  
completely.  Another task will be to inventory the functions defined  
in PGauxiliaryfunctions.pl
(and perhaps PGcommonFunctions.pl) and see which of them should be  
added either to the general context or added to specialized
contexts so that the functions can also be used in MathObjects. Many  
of them have already been added.

  In both cases the goal would be to make it easy for a new author to  
determine
(1) which "special" functions have already been defined somewhere in  
the PG files.
(2) which contexts (specialized or general) are needed in order to  
allow use
of these functions in MathObjects by instructors or students.

Take care,

Mike

John has already mentioned this, but I want to be extra clear about  
the point he made.  The PGcommonfunctions.pl and  
PGauxiliaryfunction.pl files defined commands available to the  
problem AUTHOR.  Note that C() and P() are already defined there.   
The functions available to the students in their answers is  
controlled by the Context(), and contextIntegerFunctions.pl makes C()  
and P() available to students in their answers. That certainly should  
not be the default, in my opinion.

The current plan sounds fine.

When considering where to add functions, bear in mind the issue of 
whether only problem authors will be able to use the function, or if 
students can use it in their answers.  In the second case, I suppose you 
would also need to decide if the default is to allow them to use the 
functions or not.  This was part of the rationale for the new context 
initially (by default students would not be able to use say C(n,r) or it 
would trivialize some existing problems, but in more complicated 
counting problems you might want to enable it).

By the way, does webwork have a version of PowerMod for problem 
authors?  I was thinking of using webwork with a cryptography class (it 
would be my first time!), and this was one of the first functions I wanted.

John

Re: [WWdevel] Fwd: [WWcvs] pg: problemPreserveAnswers.pl

[Michael G. <ga...@ma...>]

OK. Thanks.  I'll leave a permanent fix for this to a later release  
as well.
I'll include a note about the current work around.

The project of cleaning up the ANSWER_RULE hierarchy is on my list
but it's a fair sized project and I don't want to do it for this  
release.

Take care,

Mike

[Michael G. <ga...@ma...>]

Hi John,

It might be reasonable to add those functions later.  It's also  
possible that there are few enough of these that
they could be added to PGcommonfunctions.pl or PGauxiliaryfunctions.

Here's my plan:  For this rel-2-4-5 I'll just fix the typos and we  
can think about how to
consolidate the functions later, perhaps along with a plan for allowing
context "patches".

Take care,

Mike

[WWdevel] Fwd: [WWcvs] pg: problemPreserveAnswers.pl

[Davide P. C. <dp...@un...>]

Forgot to copy the list on this response:

EV3P is unrelated to the $ in answer blanks, so no, EV3P doesn't do  
anything about that.  (The flaw is in the various answer rule macros  
that strip those characters out rather than convert them to HTML  
entities.)

The the test case is not in the problem file itself, but in what you  
enter into it.  If you enter a $ in an answer, submit it, and it  
shows up as part of the answer already showing in the answer rule,  
then the problem is solved.  If the dollar sign is missing, then the  
problem still exists.

Re: [WWdevel] [WWcvs] pg: fixed typo by changing all references to IntegerFunction or IntegerFunctions to the plural The typo gave an immediate error

[John J. <jj...@as...>]

I did add the original version of this context.  I had someone who 
wanted students to be able to use P(n,r) and C(n,r) in their answers on 
some problems.  But, for one reason or another, he never wrote any 
problems with it for general use.

I don't see any obstruction to changing the name to 
contextCombinatorics.  I don't recall if there was some reason for 
preferring contextIntegerFunctions initially.  Maybe there was some 
thought that people might want to extend it at a later time to allow 
gcd, powermod, or some other integer functions.
