### Missing macro files

Hi Everyone,

The webwork distribution seems to be missing some macro files for some of the recently contributed problems. Foe example,

(1) When I view Library/FortLewis/Algebra/2-2-Distributive-law/MCH1-2-2-16-Distributive-law.pg I get this error: Can't locate macro file |contextPolynomialFactors.pl

(2) When I view Library/FortLewis/Algebra/6-1-Exponent-rules/MCH1-6-1-02-Exponent-rules.pg I get this error:

Can't locate object method "new" via package "ChoiceList" (perhaps you forgot to load "ChoiceList"?) at line 116 of [TMPL]/Library/macros/Union/alignedChoice.pl Died within AlignedList::new called at line 106 of [TMPL]/Library/macros/Union/alignedChoice.pl from within main::new_aligned_list called at line 53 of [TMPL]/Library/FortLewis/Algebra/6-1-Exponent-rules/MCH1-6-1-02-Exponent-rules.pg

(3) viewing Library/NewHampshire/unh_schoolib/Order_of_Operations/oopbrm101.pg results in the error: Can't locate macro file |contextLeadingZero.pl

Where can I find the necessary files?

The problems in Library/FortLewis/Algebra/5-6-Linear-systems makes the browser hang - they won't show at all.

Hi Lars,

To solve problem (1) add to this list of paths in $pg{directories}{macrosPath} the line "$courseDirs{templates}/Library/macros/FortLewis",

(2) This problem stems from running the NationalProblemLibrary trunk and rel-2-4-patches. This has been the recommended set-up, but it seems that changes were introduced into NationalProblemLibrary/macros that assumed a trunk version of pg/lib. In particular, List.pm has been changed to ChoiceList.pm so as not to cause confusion with the name of the file defining the List MathObject. This will get fixed by itself when the new stable release is released and you switch to that.

As a temporary fix, you can revert the NationalProblemLibrary/macros/Union directory to the revision before those changes were introduced (r890) with the command the following command from inside NationalProblemLibrary/macros:

svn up -r890 Union/

Regarding (3), I'm not familiar with those problems, so I don't know what's up, but I'll check it out and let you know if I find a solution.

Hope this helps,
Jason

Hi Jason,

Thanks for the reply.

Regarding (1), this particular file - contextPolynomialFactors.pl - is missing from the macros/FortLewis directory.

When is the new stable release expected to be ready?

Thanks!
Lars.

Hi Lars,

contextPolynomialFactors.pl is found in the svn trunk version (i.e. the old cvs head version) of /pg/macros. It is not in the macros/FortLewis directory.

You might be able to get by by just downloading that file. If that doesn't work, at least it will not affect anything else.

The new stable release should be ready soon although I certainly do not want to define what soon means. Mike will be working on this and he and his wife have a very well deserved vacation coming up soon. So I think it will be toward the end of August at the earliest.

I seem to be having a similar problem as Lars.  I've upgraded the pg folder and the National Problem library folder with SVN--I had a pretty current version of everything as of August thanks to Jason's help and I upgraded the two folders again today using (svn up).  I also tried putting the Union macros folder back to version r890 as Jason suggested to Lars.  The error msg I'm getting is slightly different, so it may be a whole different problem.  Here is the error message and the macros loaded in the problem.

--------------Error message--------------------

Try adding "choiceMacros.pl" to the loadMacros() list. I think that was in my original version of PGstandard.pl, but it was removed in the version that eventually made it into the pg/macros directory. I think I updated all of the Union problems to account for that, but they may have been copied as the basis for other problems, that now don't work. (Or you may have an out of date copy of the Union library.)

Hi Robin and Lars,

I think this is still a mismatch between the versions of macros found in NationalProblemLibrary/macros and the macros found in webwork/pg.

The new (trunk) versions use ChoiceList.pm while the older rel-2-4-7 uses
List.pm.

This shows up most often for NationalProblemLibrary/macros/Union/alignedChoice.pl because it is very commonly used.

In Lars case I believe he had a new version of the Union macros but an older version of pg hence the calls in alignedChoice.pl for ChoiceList were not recognized.

For Robin, I suspect that she has a new version of pg but an older version of the Union/alignedChoice.pl file (one that calls List rather than ChoiceList).

The best solution would probably be for us to move alignedChoice.pl and perhaps a few other heavily used macro files from macros/Union to the pg/macros folder in the svn repository so that they are always updated in sync with the rest of the pg macros.

Any comments on this? Is there a downside?

FYI:  I updated the Union macros files this morning and am still getting the same error message. The Union macros I have are revision 1516 and my pg files are 6430.

Thanks, that helps.

I've synced to those revisions and can't reproduce the problem.
Since I don't have that problem here -- try looking at
problem #4 of the standard Orientation set. That works fine for me and calls in all of the macro files that your example does. That problem does show errors if the macros/Union files and the pg/macros files are out of sync.

If problem #4 in Orientation is working for you then could you send your problem file and I'll see if I can reproduce the failure here.

OK.  I found my problem.  I had an old copy of the alignedchoice macro in the course macros folder.  Apparently, it was placed into a course years ago and just came along as new courses were buit from previous ones.

Thanks, everyone, for your help.  Your suggestions pointed me in the right direction.
