Removing boldface from appendix chapters in TOC

Question

How do I remove boldface from appendix chapter headings in the TOC?

I would like the TOC to look like this:

1 First chapter
  1.1 First section
Appendices
Appendix I First appendix
Appendix II Second appendix

My MWE looks like this:

    \documentclass{report}
    \usepackage[toc,page,titletoc]{appendix}

    \begin{document}
    \tableofcontents

    \chapter{First chapter}
    \section{First section}

    \begin{appendices}
    \chapter{First appendix}
    \chapter{Second appendix}
    \end{appendices}
    \end{document}

and returns

1 First chapter
  1.1 First section
Appendices
Appendix I First appendix
Appendix II Second appendix

I've looked through the titlesec and appendix packages but can't see the options, and the solution doesn't appear on Stack Exchange as far as I can tell.

Answer 1

An appropriately-placed patch in the ToC can correct this behaviour. Below I've patched \l@chapter - the macro responsible for setting the chapter-related content in the ToC - and removed \bfseries:

\documentclass{report}

\usepackage[toc,page,titletoc]{appendix}

\usepackage{etoolbox}
\makeatletter
\g@addto@macro\appendices{%
  \addtocontents{toc}{\protect\patchcmd{\protect\l@chapter}{\bfseries}{}{}{}}
}
\makeatother

\begin{document}

\tableofcontents

\chapter{First chapter}
\section{First section}

\begin{appendices}
\chapter{First appendix}
\chapter{Second appendix}
\end{appendices}

The process is automated by adding the patch to \begin{appendices}. That way you don't have to clutter your document with such code.
