# Automatically bolded first sencence of caption in listoffigures

I have used the following approach to automatically make the first sentence of a float caption bold (in combination with hyperref): Hyperref compatability with automatically bolded first sentence of float caption float.

However, additionally I also need to have a short version of the caption in my list of figures / list of tables (as most of my captions are very long). The usual way with \caption[entry in LOF]{full caption} does not work anymore. Is there a possibility to automatically depict the bold part of the caption in the LOF/LOT?

\documentclass{scrbook}
\usepackage{caption}
\usepackage{xstring}
\usepackage{hyperref}

\makeatletter
\newcommand\formatlabel[1]{%
\noexpandarg
\IfSubStr{#1}{.}{%
\StrBefore{#1}{.}[\firstcaption]%
\StrBehind{#1}{.}[\secondcaption]%
\textbf{\firstcaption.} \secondcaption}{%
#1}%
}
\AtBeginDocument{%
\newcommand*{\org@caption}{}%
\let\org@caption\@caption
\def\@caption#1[#2]#3{%
\org@caption{#1}[{#2}]{\formatlabel{#3}}%
}%
}
\makeatother

\begin{document}

\begin{figure}[tb]
\caption{First sentence is bold. Second sentence is not.}
\label{fig:figure1}
\end{figure}

\end{document}


I adapted this post to set the bold part as short description.

\documentclass{scrbook}
\usepackage{caption}
\usepackage{xstring}
\usepackage{hyperref}

\makeatletter
\def\getfirst#1.#2\relax{{#1}}
\def\getsecond#1.#2\relax{{#2}}

\AtBeginDocument{%
\newcommand*{\org@caption}{}%
\let\org@caption\@caption
\def\@caption#1[#2]#3{%
\org@caption{#1}[\getfirst#3\relax]{{\bfseries\getfirst#3\relax} \getsecond#3\relax}%
}%
}

\makeatother

\begin{document}

\begin{figure}[tb]
\caption{First sentence is bold. Second sentence is not.}
\label{fig:figure1}
\end{figure}
\listoffigures
\end{document}
