I'm trying to see how close Yoshiwara's "Modeling, Functions, and Graphs" is to
being converted to braille. Perhaps an appeal here, rather than off-list, will
yield some insights.

1. With the only publication file that is apparent, I get

failed to load external entity

2. Note that the publication file has

<source webwork-problems="../wwscratch/webwork-representations.ptx"/>

Note the suffix *.ptx v. *.xml.

Unclear to me why the failure is looking for *that* file. Note that the managed
directories scheme is not in play.

3. So I copy all of "../wwscratch/" into
/home/rob/books/mfg-yoshiwara/ptx/images/webwork/ and rename the representations
file to get the suffix right. That would seem to get me an HTML build which
proceeds without immediate errors (using pretext/pretext).

Any suggestions on what should change in the organization of this project so
that the WW problems behave?

Hi Rob,

We hadn't tried to build MFG for quite some time, and for the past few days I've made some corrections Kathy wanted. I cleaned up some but not all of the warnings regarding deprecated stuff, and I think I succeeded in getting a new html version (including re-generated WeBWorK exercises) via CLI.

So https://github.com/byoshiwara/mfg should now have a working publication.ptx file in the publication folder.

Thanks, Bruce.

I pulled last week or so, but not today.

I'll give it a go soon, a braille build is in-progress right now.

source with @webwork-problems is deprecated. Maybe not in a clear
enough and official way.

Managed directories should handle this.

Are you sure? I see it here:
Are you working with a different publication file?

There is a commit to that repo from a few hours ago. It is not clear
to me what was the status of the publication file before that.

Remove that @webwork-problems attribute, and managed directories
should do what needs to be done.

Thanks, Alex. Maybe I missed an error message before the flood of file not found messages. I'll check.

I was coming to the conclusion that managed directories we're necessary. Yes, a different publication file, but if iirc it was the only one I could find a week or two ago. Sounds like Bruce has that unber control once I pull.

No warning for an absent file. We test if the *filename* is empty, but I can't
see that we test for the file itself being AWOL.

We could do a preparatory test by making

<xsl:variable name="just-testing"
select="document($webwork-representations-file, $original)"/>

If the file is missing, we'll get one error message, and I think the variable is
empty/false, andwe can warn once more, more carefully. Then from there on we
could just fill WW exercises with "A WW exercise goes here".

OK, a pull and a new publication file and everything is good. Just got a good
HTML build.

I built braille a couple hours ago by moving around the WW stuff and it looked
pretty good (with a cursory glance). Building braille again now...

Thanks for the help.
