cline formatting in Parsons problem HTML output

[Andrew Scholer]

Mostly for Rob and Brad...

While investigating a Parsons issue, I noticed that the behavior of a cline in Parsons problems is inconsistent between @language="natural" and not natural.

When language is specified as something like "cpp", the cline text is xeroxed into the HTML. This means that a block that looked like:

      <block>
        <cline> else {</cline>
      </block>

Ends up rendered as:

---
 else {
---

Where --- is the magic string specifying the extent of a block.

However, if language is "natural", the cline gets passed through the cline template which adds a newline resulting in:

---
 else {
   
---

That extra line ends up being interpreted as a real line in the Parsons js. However, it does not get rendered visibly. This is not actively causing any bugs that I can identify - each block just has one more line than is apparent to the user. But it feels like it could cause issues.

[Rob Beezer]

Thanks, Andrew. I think entirely for Rob.

Does the sample book have an example that would hit this?

[Andrew Scholer]

If you remove the language="python" from prime-number-program-indent-yes you should see the output for the problem change.

As we discussed in drop-in yesterday, Rob changed the output format for the runestone-manifest.xml file to be html.

I made an initial attempt to process that manifest this morning, and unsurprisingly it failed.

  File "/Users/bmiller/rs/components/rsptx/build_tools/core.py", line 548, in manifest_data_to_db

    db_context = _initialize_db_context(engine, sess, course_name, manifest_path)

  File "/Users/bmiller/rs/components/rsptx/build_tools/core.py", line 579, in _initialize_db_context

    tree = ET.parse(manifest_path)

  File "src/lxml/etree.pyx", line 3589, in lxml.etree.parse

  File "src/lxml/parser.pxi", line 1958, in lxml.etree._parseDocument

  File "src/lxml/parser.pxi", line 1984, in lxml.etree._parseDocumentFromURL

  File "src/lxml/parser.pxi", line 672, in lxml.etree._raiseParseError

  File "./runestone-manifest-html.txt", line 2428

lxml.etree.XMLSyntaxError: Opening and ending tag mismatch: img line 2427 and div, line 2428, column 7

I have not looked at the code to see what my options are for parsing this to avoid the error.

Dear Brad,

You saw that there is an #img (the Luther bell!) that is not formed as an empty
element, nor does it have a closing tag? So not strictly XML. No real surprise
there, and there will be more with other elements, I expect.

Thanks for the pointer.   It is going to take a bit of work, as I used find and findall extensively which do not work with html very well.  I will all need to be convert all of those to xpath queries.

I may have hijacked the wrong thread.  OK, so I have converted the code so it reads/processes the manifest without crashing.

I looked at some assignments, and it seems we have some encoding issue to figure out.  In any case it would be great to have another set of eyes helping to test this out.  I made a CSV of relevant tables, but the diffs on the questions are impossible since the XML version formatted the htmlsrc column nicely and of course the html version of the manifest is kind of ugly.

[Andrew Scholer]

This feels worth some effort to automate.

Maybe run both versions through a tidy tool so they are better diffable?

If you have a csv or db with xml formatted and html formatted versions, you could use something like PyTidyLib to do something like this for each version:
make output file
for each question:
    grab htmlsource
    tidy it up
    append to output file

Then you could diff the files produced from the xml formatted source and the html formatted source.

If you get a mostly automated process set up, I would be happy to diff a few books and submit things that look broken.

Those problem characters are Unicode apostrophes and "smart quotes", and are
identical in the XML version (old) and the HTML version (new).

But the XML version has a first line like:

<?xml version="1.0" encoding="UTF-8"?>

while the HTML version has *nothing*.

I'll see if I can change a couple of things to make the right stuff come out (or
at least something better), or you can add something by hand if you want to make
progress right now.

Rob

[Bradley Miller]

Yeah,

I solved the encoding problems and it looks good now.

Is there an exercise that was exhibiting the problem Sean was having so that we can verify whether or not all of these changes have made a difference.

I do think this needs more careful scrutiny before merging any of this. We have had years of stability in the manifest and I would hate to throw courses into chaos over a bad xpath query!

This Parsons problem was the instigator:

So, it would be good to get that question into the sample book so we can test and make sure this is solving the problem.

I’m surprised we are not seeing this problem more?  Maybe because this isn’t a programming problem.

The key features that I think are necessary to trigger this:
* It is natural language, not programming.

* It has embedded math (or some other markup that introduces newline characters as it is rendered as XML).

The existing `number-theory-proof` already meets those criteria and displays the issue.

But... you only see evidence of the issue when you try to solve it on a book page and then go look at your solution on a DB driven page (assignment page or grading page). It works fine in either context, but it is different in the two contexts so your saved solution from one does not make sense in the other.

That combination of factors is why we aren't seeing it more. Sean did his thing and found the edge case no one else was using. :)

Rob, Andrew

OK, I checked the number-theory-proof question.  #6 on the parsons page.

Still broken even with the html based manifest, comparing the second block

MANIFEST

---

<div class="para" id="number-theory-proof-numbered-left-4-2-1-1">Then <span class="process-math">\(n\)</span> is a prime number.</div> #paired

---

HTML

---

<div class="para" id="number-theory-proof-numbered-left-4-2-1-1">Then <span class="process-math">\(n\)</span> is a prime number.<div class="autopermalink" data-description="Paragraph"><a href="#number-theory-proof-numbered-left-4-2-1-1" title="Copy heading and permalink for Paragraph" aria-label="Copy heading and permalink for Paragraph">🔗</a></div>

</div> #paired

---

There seems to be some extra stuff in my html about permalinks….. I wonder if that is what is injecting the newline.   Read on!

— time passes —

OK, updated to 2.30.0 — Thanks Oscar!

Rebuilt, deleted old answers from the database, cleared localstorage.

Solved the problem in context on the first try!  I have it memorized now.

Went to the assignment page, and Tada there it is!

OK, this still seems somewhat bad that we have some closing divs on their own lines (after a span with a class of process-math) But at least the manifest and the html are consistent.

Good work, Brad.

Yes, we thought putting permalinks onto the page was a good idea, rather than
having Javascript find gthe right places and add them in. We (Andrew, Oscar)
have been finding places where they are too much and killing them. For me, I
think children of divisions (including #paragraphs) might be enough? A
#theorem, but not every #p within it? I'm sure some will think that leans too
far the other way.

OK, having said that, how about an even bigger suggestion. I've learned the
harway that copies of content are fraught. Knowls, WW, manifest, and probably more.

What if the manifest's #htmsrc element just held a *pointer* into the HTML? Go
grab the original, don't just make a copy? Something like

<htmlsrc the-file="sec-number-theory.html" id="ANT_3_number-theory-proof"/>

(Then the manifest could go back to XML!)

That sounds like a big lift!  

It would further complicate things by having the html for exercises in two places.  In the html for the book which would need to be parsed and extracted, and in the database for questions written in the assignment builder.

I’m open to discussing more, but it feels like a lot of work for minimal benefit.

I think only having one render path is a big win. I don't see a non-kludgey way to fix the current cline issue without that. And I would not be surprised if we see another issue down the line related to rendering differences between the two outputs.

The htmlsrc would not have to be grabbed at page render time. Instead, the process-manifest function could be responsible for using the manifest to grab the right html chunk from the html file as it is being processed. So the htmlsrc would still go in the DB and no other logic would change.

This would mean that the manifest file would no longer be standalone. I'm not sure that is a deal breaker, but does make "send me your manifest" a less useful debugging tool.

I didn't really say it, but that was what I was imagining. Copy the HTML out of
the served pages into the DB. Once.

Ash, "self-contained". Wasn't sure at first what you meant by standalone.

Ok sounds better.

The manifest file lives with the html files after the build, and my runestone build script processes the manifest immediately after the pretext build finishes.

Its not quite as simple as searching the html file for the label as often PTXSB_2_xyz  is a descendant of a <div class=“ptx-runestone-container”><div class=“runestone multiplechoice_section”> and may have a sibling of a <div class=“exercise-statement”>

probably finding the label and working back to the nearest ptx-runestone-container will work… Or do we want to construct and id for the outermost div?

I don’t think in xpath!! 

Clearly this can be done with a single xpath query and no need for any additional attributes.

Well, get with the program!!! ;-)

And I shouldn't have suggested the @id look like the Runestone version of the
@label. The outermost #div of a Runestone-thing on its served page can have a
unique #id and then that string can be replicated in an attribute of the
#htmlsrc. "find()" might even be enough.

And we could even phase it in. Want me to make a test version, maybe for our
friend, the Parsons problems?

Here is another thing I found while thinking about this puzzle.

It looks to me as though we have a mismatch in our assumptions about the default language.  In the parsons javascript we look for a data-language attribute, it it is not there we look for eBookConfig.language and if neither are there we assume the language to be “python”

The number theory proof question does not specify the language.

AFAIK every Parson problem should end up with a @data-language on the <pre>. The XSL for them checks to see if there is a programming language defined. That value can be an attribute in the exercise or a book-level default specified in docinfo. If no language is found, 'natural' is used.

The manifest for the problem you mention shows:
                                <pre class="parsonsblocks"
                                     data-question_label=""
                                     style="visibility: hidden;"
                                     data-language="natural"
                                    ...

So whatever the JS is doing other than looking at data-language should never come into play for PTX authored problems.
