I am using book class and I want to create a part in TOC in the following way:

I want the part centred in the middle of the page and the chapters on the other page.

Here is my code:

documentclass[12pt]{book}

    makeatletter

    def@part[#1]#2{%

    ifnum c@secnumdepth >-2relax

      refstepcounter{part}%

      addcontentsline{toc}{part}{protectnumberline{thepart}#1}

    else

      addcontentsline{toc}{part}{#1}%

    fi

    markboth{}{}%

    {centering

     interlinepenalty @M

     normalfont

     ifnum c@secnumdepth >-2relax

       hugebfseries partnamenobreakspacethepart

       par

       vskip 20p@

     fi

     Huge bfseries #2par}%

    @endpart}

    renewcommandl@part[2]{%

    thispagestyle{empty}

    newpage 

    vspace*{fill}

    begin{center}

    defnumberline##1{%

    Large Part~ ##1newline

    }

    {Huge #1}

    end{center}

    vspace*{fill}

    newpage

     }

    makeatother



    begin{document}





    tableofcontents



    part{one}



    chapter{one \ two}

    chapter{two}

    chapter{three\three\three\three\three}

    chapter{four}



    part{two}



    chapter{five}

    chapter{six}

    chapter{seven}

    chapter{six}

    chapter{seven}

    chapter{six}

    chapter{seven}

    end{document}

I already put the part in a separated page, but I do not know why I can not change the font size of the TOC (i.e., why Large, Huge do not work in l@part) and I can not put the empty page on this too (i.e., why thispagestyle{empty} does not work in l@part).

Note the use of two sets of braces in the redefinition of numberline. The second set makes Large local.

Also, I wasn't sure if the use of newline was deliberate.

documentclass[12pt]{book}

makeatletter

def@part[#1]#2{%

ifnum c@secnumdepth >-2relax

  refstepcounter{part}%

  addcontentsline{toc}{part}{protectnumberline{thepart}#1}

else

  addcontentsline{toc}{part}{#1}%

fi

markboth{}{}%

{centering

 interlinepenalty @M

 normalfont

 ifnum c@secnumdepth >-2relax

   hugebfseries partnamenobreakspacethepart

   par

   vskip 20p@

 fi

 Huge bfseries #2par}%

@endpart}

renewcommandl@part[2]{%

newpage 

thispagestyle{empty}

vspace*{fill}

begin{center}

defnumberline##1{{Large Part~ ##1\}}%

{Huge #1}

end{center}

vspace*{fill}

newpage

 }

makeatother
