Including a Doenet activity

[jfir...@linfield.edu]

I am trying to include a Doenet activity in a textbook. I have the activity as a separate file and am using xi:include as follows:

<interactive label="doenetminimaxgraph" platform="doenetml" width="100%" aspect="40:43">
          <slate surface="doenetml">
           
            <xi:include parse="text" href="doenet/minimaxgraph.xml"/>
           
          </slate>
  </interactive>

It seems that the xi:include is the main issue as I am getting a warning:

warning: Failed to map codechat path to xml id; codechat will not work.

When I comment out the interactive (or just the xi:include statement ) I do not get this warning. I tried a minimal amount of text in the minimaxgraph.xml file and I still get this error.

Other than this warning, does your document build and display things correctly?  Codechat is a way to preview files side by side, and isn't strictly necessary for pretext.

Dear Jen,

I was waiting to hear from Oscar.

Shot in the dark - try putting an @xml:id on the #interactive and the #slate, just to see what happens.

I *think* this might be related to a missing "xmlns:xi="http://www.w3.org/2001/XInclude""

I get the mysterious codechat error if the toplevel element on a page is missing that namespace declaration. e.g.
<chapter xml:id="ch-chapter-title">
instead of 
<chapter xml:id="ch-chapter-title" xmlns:xi="http://www.w3.org/2001/XInclude">

Jen:
Do you see an error like this on your xi:include?


And can you try this in the terminal:
pretext -v DEBUG build

See if that shows an error like:
lxml.etree.XMLSyntaxError: Namespace prefix xi on include is not defined...

Likely a missing namespace decleration in Jen's source, but she would never know
since the error reporting (from the XSL processor, not PreTeXt) was a bit wonky.

Andrew S has devised a fix, which was just merged, and will roll out in the
usual progression. Nice work on Andrew's part.

Thanks very much, Jen, for providing a report. You've saved a lot of
head-scratching for a lot of folks down the road.

Thanks everyone! It was Andrew who caught the error. I needed the xmlns:xi statement on the page. It will now include a simple version of the activity (text  and math only). However, I get errors for <mathinput> and the "simplify" attribute on the html output. Maybe someone has experience putting interactive Doenet activities in PreTeXt books. As a fall back, I can include the link to the Doenet Activity (I works fine on their site): https://doenet.org/portfolioeditor/_iR2WJvOBDdOFkCkep7LgL/_Z6T9avWGsLhNuP9QitQVK

I can include a screenshot of the errors on the html, if that would be helpful, but I was having trouble adding screenshots here.

[jfir...@linfield.edu]

Thanks everyone! It was the missing <chapter xml:id="ch-chapter-title" xmlns:xi="http://www.w3.org/2001/XInclude"> on the section page that Andrew caught. It now includes the activity, but there are issues as it gives me a bunch of errors.  In particular, I get errors in the output for <mathinput> and "simplify" attributes. It includes the activity without errors if I just have text. I don't know if there are people who have put complicated Doenet activities in their books and have found ways to fix these errors, or if these types of activities are not yet compatible. I have attached a screenshot of what the html looks like, just in case anyone has ideas of how to fix them. The Doenet activity runs well on the Doenet site: https://doenet.org/portfolioeditor/_iR2WJvOBDdOFkCkep7LgL/_Z6T9avWGsLhNuP9QitQVK

As a temporary fix, I can certainly just include the link to the activity in the book.

Jen -

It looks like doenet expects <mathInput> not <mathinput>. 

https://doenet-ml.vercel.app/reference/doenetML_components/componentTypes#input-components

For some reason the portfolio accepts either one, but the javascript library used to load doenet activities is more picky.

Thanks Andrew,

Yes, <mathInput> fixed the error. The "simplify" error was also that I needed <math> tags, not <m> tags when there was an attribute.
