How to make xkvview record keyreader defined keys?

Question

Since keyreader is based on xkeyval i wonder if it’s possible to make it wokr with xkvview which comes with xkeyval.

\documentclass{scrartcl}

\usepackage{xkvview}
\usepackage{keyreader}

\makeatletter

% recorded
\define@boolkey{LI@package}[li@]{savemode}[true]{}
% not recorded
\krddefinekeys{LI@all}[li@]{%
   cmd/testa/;
}


\begin{document}
\xkvview{}
\end{document}

The example shows that keys defined with the xkeyval way are recognized but not the ones defined via keyreader. I thought keyreader uses the xkeyval commands internally so I expect it to be also in the \xkvview{} list

Answer 1

keyreader works with xkvview. Load keyreader before xkvview. Here is an example:

\documentclass{article}
\usepackage{keyreader}
\usepackage{xkvview}
\makeatletter
\krddefinekeys{fama}{%
  ord/keya/default;
  cmd/keyb;
  choice/keyc/center/center.do=\def\x##1{#1xx##1},left,right;
  bool/keyd/true;
}
\krddefinekeys{famb}{%
  choice/planet/Earth/Earth.do=\def\x##1{#1##1},Mars,Jupiter;
  bool/space travel/true;
}
\makeatother
\begin{document}
%\xkvview{family=fama,default=[none]}
\xkvview{family=fama}
\end{document}

I have to investigate why keyc is shown twice in this table.

EDIT:

keyc is shown twice because of a bug in the package xkvview. I provide a patch below:

\def\XKV@d@fine@ch@icekey#1[#2]{%
  \let\d@fault\relax
  \XKVV@tabulate{#1}{choice}{#2}%
  \XKV@define@default{#1}{#2}%
  \XKV@d@fine@ch@ic@key{#1}%
}
\def\XKV@d@fine@ch@ic@key#1{%
  \ifx\d@fault\relax
    \let\d@fault\@undefined
  \else
    \XKVV@tabulate{#1}{choice}{[none]}%
  \fi
  \ifXKV@pl\XKV@afterelsefi
    \expandafter\XKV@d@f@ne@ch@ic@k@y
  \else\XKV@afterfi
    \expandafter\XKV@d@f@ne@ch@ic@key
  \fi
  \csname\XKV@header#1\endcsname
}

The patch should be inserted at the end of xkvview or after loading xkvview.
