Choices does not support relate markdown

[KlavsKlavsen]

According to the docs, the Choices support relate markdown - which is documented here https://documen.tician.de/relate/content.html#markup - but if I try to give it this:

         choices:
           - ```python
             def f(x):
             return 5+x
             ```

it fails with: Course content did not validate successfully: 'flows/skills-quiz-general.yml: ScannerError: while scanning for the next token found character '`' that cannot start any token in "", line 80, column 13: - ```python ^' Update not applied.

[KlavsKlavsen]

Even if I add such a section in the text for the question - it renders, but IMHO incorrectly as it looks like this rendered (also the case in the markdown test page):

A
<pre >  umbreallachart
    image
      tag v1.7.0
</pre> 

the pre html tags really should not be visible and the "block background color' - should form a box - like it does here on github, and not just cover the actual text inside the backticks.

[KlavsKlavsen]

the < pre > disappears IF I indent the backticks AND put a : after the line directly above (very odd)

          A:
 
             ```
             umbreallachart:
               image:
                 tag: v1.7.0
             ```

[inducer]

It does. But you need to use a YAML multi-line literal, like so:

type: ChoiceQuestion
id: fp_accuracy
shuffle: True
prompt: |
    # Floating point "machine epsilon"
    For a (binary) floating point system of the form
    $(s_1.s_2s_3)_2\cdot 2^{p}$ that has an exponent range from $-128$ to
    $127$ and that uses three bits to store the significand $s$, what is the
    difference between 1 and the smallest representable number greater than
    one?
choices:
    - $2^{-3}$
    - $2^{-4}$
    - |
      ```
      print("Hi")
      ```
    - ~CORRECT~  $2^{-2}$
answer_explanation: |

    That's just what it is.

Otherwise YAML will glue everything together into one line (without newlines) and Markdown will be mildly confused.

[KlavsKlavsen]

I tried to do that exact thing, and it complains about the backticks still

[KlavsKlavsen]

This fails to parse correctly too:
ip a says:

            ```
            3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
               link/ether 34:cf:f6:f5:8d:36 brd ff:ff:ff:ff:ff:ff
               inet 192.168.1.8/24 brd 192.168.1.255 scope global dynamic noprefixroute eth0
               valid_lft 1806101sec preferred_lft 1806101sec
            3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
               link/ether 34:cf:f6:e5:8d:36 brd ff:ff:ff:ff:ff:ff
               inet 192.168.2.3/24 brd 192.168.2.255 scope global dynamic noprefixroute eth1
               valid_lft 1806101sec preferred_lft 1806101sec
               ```

[inducer]

Could you post a full question example? That'd make it easier for me to see what's going on. One thing to be aware of is that Markdown views "indentation by 4" as "code literal". (That's in the Markdown spec.) I saw some <pre>s in the output you posted, which got me suspicious.

full question:

     -

Not sure what you're trying to accomplish, but https://gist.github.com/inducer/155204d2506dc1a69a297e5e8bee0e78 looks reasonable to me.

[KlavsKlavsen]

This is how the 'ip a' output renders in my browser - using above markup :(

[inducer]

If I render the YAML from the gist in the sandbox, I get the following:

[KlavsKlavsen]

in which browser? I have tested this in both firefox and chrome and it renders the exact same way :(

[KlavsKlavsen]

skills-quiz-general.zip

I have attached my full flows file so you can see.

[inducer]

It doesn't look like you're making use of my modifications from the gist.

[KlavsKlavsen]

I copy'pasted your gist in - and indented only (to match existing indention) - and it ALMOST loooks ok.

1. it shows

    tags

2. I do noget a big square around the 3xbackticked text like you have ?

[inducer]

Check if you have "may show untrusted HTML" set in the record for your course in the admin. I have a feeling this might be the HTML sanitization gone astray. (I'll take a look tomorrow.)

[KlavsKlavsen]

That did indeed fix it. Thank you for your help :)

[inducer]

#931 makes this work without that flag.
