Auto Multiple Choice - Error on AMCOpen scoring on latest code

Error on AMCOpen scoring on latest code

I'm have a script that generates a set of options for open questions (so I can grade them).

Basically, I loop over a set of numbers and create the options. This worked before (I'm just testing the new version) and it seems to be broken.

My default setup is something like:

% macro to automatically create open choices
\pgfkeys{
  lines/.store in=\@oc@lines,
  lines/.default=6,
  max/.store in=\@oc@max,
  max/.default=4,
  step/.store in=\@oc@step,
  step/.default=0.5
}
\newcommand{\AMCOpenChoices}[1][]{
  \pgfkeys{ %
    /pgf/number format/fixed,
    /pgf/number format/precision=1,
    lines, max, step, #1}
  \AMCOpen{lines=\@oc@lines,dots=false}{ %
  \pgfmathparse{\@oc@max-\@oc@step}%
  \foreach \i in {0, \@oc@step, ...,\pgfmathresult}{ %
    \pgfmathprintnumberto{\i}{\tmp}%
    \wrongchoice{\tmp}\scoring{\tmp}%
  }%
  \pgfmathprintnumberto{\@oc@max}{\tmp}%
  \correctchoice{\tmp}\scoring{\tmp}%
  }%
}

As you can see I'm creating a correctchoice and several wrongchoices.

However, with this setup the markings produced 0 for that questions.

When I change the scoring to look something like

\scoring{b=\tmp,v=0,e=0,m=0}
\scoring{b=\tmp}

It produces a 1 in the answers (I guess it is picking the default score), regardless of the other values. However, the \tmp macro holds the correct value since the values in the test are printed correctly.

Did the scoring function change? What am I missing?

This worked before (I'm just testing the new version)

With which AMC version is it working, and with which is it broken?

And can you provide a minimal complete source file?

I'm attaching a MWE so you can see the problems.

To be honest, I don't remember the version that worked before. I use the same script last year at the beginning of the year and it was working.

Now, I'm using the open questions again and it is giving some errors.

Please check the attached example.

Note that the scores of pref questions do not match with the expected scoring. That is, pref should be max 3, and pref-manual should be 3. In my case it shows 7 and 4 respectively.

My AMC version is 1.3.0+hg2018-03-07. And pdfTeX 3.14159265-2.6-1.40.18 (TeX Live 2017)

Let me know if knowing the version of other packages may help.

I also tested with the Auto Multiple Choice 1.3.0 version from the amc ppa and I see the same behavior.

Getting 7 and 4 on the scripted and manually created questions. However, I was expecting to see a max of 3 on both.

Any suggestions on how to get the expected behavior?

Thanks for the MWE. Two points:

the syntax \scoring{1} is only valid for simple questions (and ignored in multiple questions). I think that is what you are looking for here, so use question instead of questionmult for your two open questions.
your \tmp macro expands to (for example) $1.5$ , and as an argument of \scoring we need only 1.5 (without the $). Use the unformatted value instead: \i and \@oc@max for the two \scoring calls, instead of \tmp.

That solve it.

Thank you!
