I'm having an issue creating a \book section above \part. All goes well — ToC is beautiful — until I add the bookmark package and then it crashes with a "Missing Action" on the first use of \book.

Thanks go so far to @Gonzalo Medina for their answer to this question for help adding the [\subsubsubsection][1] and to @lockstep for their comment on this question that led me to the chngcntr package.

Since I'm making \book above \part, I've read in the titlesec documentation that I'm supposed to do the loadonly package option on titlesec and redefine all the levels from scratch. But I really like the rest of the sections the way they are!

I just found this question with the default formatting and spacing of sections for standard classes (thanks to @Miotto!) but I'm not sure if I still need the \@startsection bits of the \subsubsubsection bits for changing \paragraph and \subparagraph ToC levels. Do the \toclevel@ bits do that by themselves?

Can someone either help me fix this MWE or help me decipher the \@startsection issue just mentioned?

MWE:

\documentclass{book}

% this part breaks the whole thing at the first occurence of \book
\PassOptionsToPackage{bookmarks=true,bookmarksopen=true,bookmarksnumbered=true,
            bookmarksopenlevel=6,
            colorlinks=true,
            linkcolor=blue,
            anchorcolor=blue
            }{hyperref}
\usepackage{bookmark}


\usepackage{titlesec,titletoc}
\usepackage{xparse}


\usepackage{chngcntr} % to change within of counters


% new book sectioning level
\titleclass{\book}[-2]{page}

\titleformat{\book}{\centering\normalfont\huge\bfseries{}Volume \thebook\\Huge}{}{0pt}{}
\titlespacing*{\book}{0pt}{3.25ex plus 1ex minus .2ex}{1.5ex plus .2ex}


% attach part counter to book
\titleclass{\part}{page}[\book]
\counterwithin*{part}{book}
\titleformat{\part}{\centering\normalfont\huge\bfseries{}Part \thepart\\Huge}{}{0pt}{}


% fix chapter -- somehow above broke it?

\titleformat{\subsubsubsection}{\normalfont\normalsize\bfseries}{\thesubsubsubsection}{1em}{}

% attach paragraph counter to subsubsubsection

\counterwithout{paragraph}{subsubsection}
\counterwithin{paragraph}{subsubsubsection}

\begin{document}

\end{document}

Also, I've tried the memoir class, but it messes up too many spacing settings to be worth my time. I like the rest of my document as is and just want to continue the writing in a new volume while still using the book class.

Thank you for your time!

[1]: I did have to use chngcntr to relink the \paragraph to the new \subsubsubsection, but all else was great! Really helpful stuff!

  • well at first you should load bookmark/hyperref later. But the main problem is that your new sectioning command \book defines also a command \bookmark and that clashes with the \bookmark command from the bookmark package. The chngctr package is no longer needed in a current latex (but doesn't harm either). – Ulrike Fischer May 05 '22 at 18:55
  • @UlrikeFischer I didn't know it made a \...mark as well. That explains a lot. I'll try calling it volume and see if that does any better! – Craie May 06 '22 at 01:33
  • I tried to edit that comment but missed the 5 minute mark by a few seconds. Just wanted to say: It did! That's wonderful! Thank you so much! I'd love to accept this as the answer. Why does titlesec make the \...mark macros? – Craie May 06 '22 at 01:40

(Allmost) all Sectioning commands have an accompanying command to set the marks for the header. There is e.g. \chaptermark, \sectionmark, \subsectionmark. When titlesec sets up a new sectioning command it therefor defines also a \...mark command. And so your \book creates a \bookmark which clashes with the command \bookmark command from the bookmark package.

Using another name e.g. \volume resolves the problem.

bookmark loads hyperref and so should normally be loaded after all other packages (with a few exceptions) but before you define the new counter.
