Get acronym withpage to work with \acfi instead of \ac

Question

I am trying to format my acronyms and want to use \acfi instead of \ac (which makes the word italic).

The problem is, withpage seems to work only for the \ac command, so the page information for acronyms introduced with \acfi.

Is there a way to add the acfi command to the withpage option? Or is there an easier solution for this? I've found this Post, but it does not solve my issue: acro package: Italicize first occurrence of term

\documentclass{article}  
\usepackage[printonlyused, withpage]{acronym}

\begin{document} 

\section{Acronyms}
\begin{acronym}[Bash]
 \acro{A}{Apple}
 \acro{B}{Ball}
 \acro{C}{Cat}
\end{acronym}

This an \ac{A}, this is a \acfi{B}, but I can't think of a word with C.

This is the \acs{A}\acs{B}\acs{C}

\end{document}

This is the result:

As this is my first Tex question, I wonder if there is a way to add a running example + output directly?

Answer 1

The \acfi macro calls \acfi which is defined as

\newcommand{\acfia}[1]{%
  {\itshape \AC@acl{#1} \nolinebreak[3]} (\ifAC@starred\acs*{#1}\else\acs{#1}\fi)}

Comparing this with the internal definition for \acf

\newcommand*{\@acf}[1]{%
    \ifAC@footnote
       \acsfont{\AC@acs{#1}}%
       \footnote{\AC@placelabel{#1}\AC@acl{#1}{}}%
    \else
       \acffont{%
          \AC@placelabel{#1}\AC@acl{#1}%
          \nolinebreak[3] %
          \acfsfont{(\acsfont{\AC@acs{#1}})}%
        }%
     \fi
     \ifAC@starred\else\AC@logged{#1}\fi}

We see that \acfia seems to be lacking the \AC@placelabel{#1} which appears to be responsible for producing the label.

Adding this in to the definition as (I've also played with the spacing as I think there above definition has two spaces between the long and short versions)

\renewcommand{\acfia}[1]{%
    {\itshape\AC@placelabel{#1}\AC@acl{#1}\nolinebreak[3] }(\ifAC@starred\acs*{#1}\else\acs{#1}\fi)%
}

Running this then creates the label, it also causes the acronym to be marked as used (with the initial definition of \acfia, \acfi{B} \ac{B} becomes "Ball (B) Ball (B)" whereas using the redefinition above the same yields "Ball (B) B".

\makeatletter
\renewcommand{\acfia}[1]{%
    {\itshape\AC@placelabel{#1}\AC@acl{#1}\nolinebreak[3] }(\ifAC@starred\acs*{#1}\else\acs{#1}\fi)%
}
\makeatother

\begin{document} 

\section{Acronyms}
\begin{acronym}[Bash]
 \acro{A}{Apple}
 \acro{B}{Ball}
 \acro{C}{Cat}
\end{acronym}

This an \ac{A}, this is a \acfi{B}, but I can't think of a word with C.

This is the \acs{A}\acs{B}\acs{C}
