A new course, rollins-mat140, was created for me yesterday (thank you, Rajiv) on the Rochester server. I used the Library browser to find some discrete math problems, and I created a new problem set called MAT140ProbSet1-Logic and imported about 14 problems that I found. There are several more I intend to import, but I want to first experiment with these in order to become familiar with the system. In particular, my plan was to import various problems, use some as is, but modify others. For instance, one of the problem files I imported was Library/ASU-topics/setDiscrete/katie5.pg, which was a truth table problem. What I’m hoping to do is create a bunch of truth table problems using that particular one as a template. Because I know nothing about the PG language and I only have a few weeks before my class begins, being able to modify problems that other folks have created is critical to my initial experimentation with Webwork.
I’m hoping you can help resolve the following difficulty I’ve encountered.
The full pathname of the original .pg file for the first problem I imported was Library/Rochester/setDiscrete1Logic/ur_dis_1_1.pg.
I modified parts of the problem and I selected Save as a renamed the path name, local/Library/Rochester/mat140jy/jy1.pg. Notice that I chose to change the subfolder name “setDiscrete1Logic” to “mat140jy” to help me identify this new set of problems I was creating for my course. I hope that was okay to do.
I modified the .pg file once again, but when I tried to save it to the same jy1.pg file, the following message appeared:
File '[TMPL]/local/Library/Rochester/mat140jy/jy1.pg' exists. File not saved. No changes have been made. You can change the file path for this problem manually from the 'Hmwk Sets Editor' page
So from the Hmwk Sets Editor I selected Save As local/Library/Rochester/mat140jy/jy2.pg, and the modified problem appears as I want it. Does this mean that the jy1.pg file is essentially a dead file, or is there some way I can delete it or overwrite it?
In summary, when I create a pathname starting with “local/”, is there a way that I can reuse that particular filename for subsequent modifications?
Thanks in advance,
