I need to store some parameters in a document and later be able to retrieve them. I’m sharing the code with you:
\documentclass{article}
\usepackage{tikz}
\pgfkeys{
/myKeys/.is family,
}
\newcommand{\readDynamicKey}[1]{
\pgfkeysifdefined{/myKeys/#1}%
{Value of Key #1 = \pgfkeysvalueof{/myKeys/#1}}%
{Key #1 not found}
}
\begin{document}
Reading all keys immediately after being created\\
\def\n{1}
\pgfkeyssetvalue{/myKeys/A\n}{A\n}
\readDynamicKey{A\n}\\
\foreach \n in {2,...,3}{
\pgfkeyssetvalue{/myKeys/A\n}{A\n}
\readDynamicKey{A\n}\\
}
\par\medskip
Reading all keys later\\
\foreach \n in {1,...,3}{
\readDynamicKey{A\n}\\
}
\end{document}
However, the compiler's response is:
Reading all keys immediately after being created Value of Key A1 = A1 Value of Key A2 = A2 Value of Key A3 = A3 Reading all keys later Value of Key A1 = A1 Key A2 not found Key A3 not found
It seems that the keys are being saved, but later I can't retrieve them. Could you help me resolve this?
