I am trying to write a document class highschool.cls for the high school research papers in our school based on the book.cls in order to make the format of the papers standardized. I am trying to define a signature page with heading ``CERTIFICATION'' such that the following text appears on the page.

enter image description here

To achieve this, I made the following definitions on LaTeX class highschool.cls.

\NeedsTeXFormat{LaTeX2e}[1995/12/01]
\ProvidesClass{highschool}
                      [2012/08/22 v0.1e
         Standard LaTeX document class]

\newcommand\@ptsize{}
\newif\if@surnamea  \@surnameafalse
\newif\if@surnameb  \@surnamebfalse
\newif\if@surnamec  \@surnamecfalse
\newif\if@firstnamea    \@firstnameafalse
\newif\if@firstnameb    \@firstnamebfalse
\newif\if@firstnamec    \@firstnamecfalse
\newif\if@midinitiala    \@midinitialafalse
\newif\if@midinitialb    \@midinitialbfalse
\newif\if@midinitialc    \@midinitialcfalse

\setlength\paperheight {11in}%
\setlength\paperwidth  {8.5in}%
\setlength\textwidth   {6in}%

\def\defenseDate#1{\gdef\@defensedate{#1}}
\def\surnamea#1{\gdef\@surnamea{#1}}
\def\firstnamea#1{\gdef\@firstnamea{#1}}
\def\midinitiala#1{\gdef\@midinitiala{#1}}
\def\surnameb#1{\gdef\@surnameb{#1}}
\def\firstnameb#1{\gdef\@firstnameb{#1}}
\def\midinitialb#1{\gdef\@midinitialb{#1}}
\def\surnamec#1{\gdef\@surnamec{#1}}
\def\firstnamec#1{\gdef\@firstnamec{#1}}
\def\midinitialc#1{\gdef\@midinitialc{#1}}

\if@compatibility
  \renewcommand\@ptsize{0}
\else \DeclareOption{10pt}{\renewcommand\@ptsize{0}} \fi
\DeclareOption{11pt}{\renewcommand\@ptsize{1}}
\DeclareOption{12pt}{\renewcommand\@ptsize{2}}
\ExecuteOptions{12pt,oneside,final,openright} 
\ProcessOptions
\input{bk1\@ptsize.clo}

\def\signaturep{ %% signature page..
   \topmargin 0in \headsep 0in
   \begin{center}
   \textbf{CERTIFICATION}\\[6pt]
   \end{center}
   This is to certify that this research paper entitled,
   \textbf{``{\uppercase\expandafter{\@title}}''} and submitted by
  \textbf{\uppercase\expandafter{\@firstnamea} \uppercase\expandafter{\@midinitiala}. \uppercase\expandafter{\@surnamea}}, \textbf{\uppercase\expandafter{\@firstnameb} \uppercase\expandafter{\@midinitialb}. \uppercase\expandafter{\@surnameb}}, and \textbf{\uppercase\expandafter{\@firstnamec} \uppercase\expandafter{\@midinitialc}. \uppercase\expandafter{\@surnamec}} 
   to fulfill part of the requirements for
   the course Science and Technology Research II was successfully
   defended and approved on \expandafter{\@defensedate}.
}%% signature page

\def\prelim{%%prelim page
\typeout{Making SMCT preliminary headings...}%
   \pagestyle{plain}
   \pagenumbering{roman}
   \signaturep \newpage
   \baselineskip=20pt
} %%prelim

\endinput

In my source TeX file, I would type something like

\documentclass{highschool}

\defenseDate{18 August 2012}
\title{This is the Title of the Paper}
\surnamea{Author}
\firstnamea{First}
\midinitiala{N}
\surnameb{Author}
\firstnameb{Second}
\midinitialb{N}
\surnamec{Author}
\firstnamec{Third}
\midinitialc{N}

\begin{document}
\prelim %% Prints Preliminary chapters

\end{document}

What I want to achieve is that

  • when there are no \surnameb,\firstnameb,\midinitialb,\surnamec,\firstnamec, and \midinitialc declared, I get the following text:

enter image description here

  • when there are no \surnamec,\firstnamec, and \midinitialc declared, I get the following text:

enter image description here

  • and when all are declared, I get the text: enter image description here

Is it possible to do this? If it is, how do I do it?

The following solution is based on these assumptions:

  1. You can only have

    • Author 1; or
    • Author 1, and Author 2; or
    • Author 1, Author 2, and Author 3

    and not, for example

    • Author 1, and Author 3; or
    • Author 2, and Author 3; or
    • Author 2 only; or
    • Author 3 only.
  2. It is sufficient to supply only a first name to distinguish whether an author "exists" or not.

The second condition can be modified, but it seemed logical that one would have a first name and a surname and possibly a middle initial, but never not a first name. Consequently, you can then use the following definitions:

\def\defenseDate#1{\gdef\@defensedate{#1}}
\def\surnamea#1{\gdef\@surnamea{#1}\@surnameatrue}
\def\firstnamea#1{\gdef\@firstnamea{#1}\@firstnameatrue}
\def\midinitiala#1{\gdef\@midinitiala{#1}\@midinitialatrue}
\def\surnameb#1{\gdef\@surnameb{#1}\@surnamebtrue}
\def\firstnameb#1{\gdef\@firstnameb{#1}\@firstnamebtrue}
\def\midinitialb#1{\gdef\@midinitialb{#1}\@midinitialbtrue}
\def\surnamec#1{\gdef\@surnamec{#1}\@surnamectrue}
\def\firstnamec#1{\gdef\@firstnamec{#1}\@firstnamectrue}
\def\midinitialc#1{\gdef\@midinitialc{#1}\@midinitialctrue}

\def\signaturep{ %% signature page..
  \topmargin 0in \headsep 0in
  \begin{center}
  \textbf{CERTIFICATION}\\[6pt]
  \end{center}
  This is to certify that this research paper entitled,
  \textbf{``{\MakeUppercase{\@title}}''} and submitted by
  \textbf{\MakeUppercase{\@firstnamea} \MakeUppercase{\@midinitiala}.\ \MakeUppercase{\@surnamea}}%
  \if@firstnameb, \if@firstnamec\else and \fi
  \textbf{\MakeUppercase{\@firstnameb} \MakeUppercase{\@midinitialb}.\ \MakeUppercase{\@surnameb}}\if@firstnamec, \else\space\fi
  \if@firstnamec and \textbf{\MakeUppercase{\@firstnamec} \MakeUppercase{\@midinitialc}.\ \MakeUppercase{\@surnamec}} \fi\else\space\fi
  to fulfill part of the requirements for
  the course Science and Technology Research II was successfully
  defended and approved on \expandafter{\@defensedate}.
}%% signature page

I've added the conditional definitions inside each of the respective author components (this is not really necessary, since only \if@firstnameX is used) and placed the conditions throughout \signaturep to include/exclude certain words/phrases/punctuation based on the truth of the conditions.

The input

\documentclass{highschool}

\defenseDate{18 August 2012}
\title{This is the Title of the Paper}
\surnamea{Author}
\firstnamea{First}
\midinitiala{N}
\surnameb{Author}
\firstnameb{Second}
\midinitialb{N}
%\surnamec{Author}
%\firstnamec{Third}
%\midinitialc{N}

\begin{document}
\prelim %% Prints Preliminary chapters

\end{document}

yields

The following minimal example adds an option to specify the list of authors as a single macro \listauthors{{<first>},{<second>},{<third>},...} using a CSV list.

enter image description here

\documentclass{article}
\usepackage{etoolbox}% http://ctan.org/pkg/etoolbox
\makeatletter
\def\@firstmiddlelast#1,#2,#3\@nil{%
  \gdef\@firstname{#1}% Extract first name
  \gdef\@middlename{#2}% Extract middle name
  \gdef\@lastname{#3}% Extract last name
}
\newcommand{\authorfml}{{\bfseries\MakeUppercase{\@firstname\ \@middlename\unskip\ \@lastname}}}% First Middle Last
\newcommand{\authorlfm}{\@lastname,\ \@firstname\ \@middlename\unskip}% Last, First Middle
\newcommand{\authorseq}{\authorfml}% Default author order
\newcounter{@list@item}\newcounter{@total@item}
\newcommand{\listauthors}[1]{%
  \setcounter{@total@item}{0}% Reset total count
  \renewcommand*{\do}[1]{\stepcounter{@total@item}}%
  \docsvlist{#1}% Count number of items in list
  \setcounter{@list@item}{1}% Start at first item
  \renewcommand*{\do}[1]{%
    \stepcounter{@list@item}% Move to next item
    \@firstmiddlelast##1\@nil% Extract first/middle/last names
    \authorseq% Print author names
    \ifnum\value{@list@item}=\value{@total@item}\relax
      , and % Second-to-last name
    \else
      \ifnum\value{@list@item}<\value{@total@item}\relax
        , % First set of names
      \fi
    \fi
  }%
  \docsvlist{#1}% Print list
}
\makeatother
\begin{document}
See \listauthors{{First1,Middle1,Last1},{First2,,Last2},{First3,Middle3,Last3},
  {First4,Middle4,Last4},{First5,,Last5},{First6,Middle6,Last6},
  {First7,Middle7,Last7},{First8,Middle8,Last8},{First9,,Last9}} from first to last. \par
\renewcommand{\authorseq}{\authorlfm}
See \listauthors{{First1,Middle1,Last1},{First2,,Last2},{First3,Middle3,Last3}} from first to last. \par
\end{document}

The definition of \authorseq determines how the titles are printed. \authorseq defaults to \authorfml which prints the author list as <first name>\ <middle name>\unskip\ <last name> (\unskip takes care of missing/non-existent <middle name> in removing the preceding control space \). Switching around the author display (for use in your abstract and introduction, if needed) is done by a redefinition of \authorseq, while formatting is controlled within the macros used (\authorfml or \authorlfm or whatever).

Thanks for the speedy reply @Werner. Indeed, your first assumption fits my problem very well. –  hpesoj626 Aug 23 '12 at 2:36
    
I am now going to accept this as the answer. My implementation was for more than ten authors and I could say that my code was a lot on the side of ugly at this point, but it works, and does not give errors. I wonder though how to do it with the second condition? (Or should I post it as another question?) Thank you. –  hpesoj626 Aug 24 '12 at 0:37
    
@hpesoj626: There are better ways of doing this. For example, it would be possible to create a macro where you just list the authors \authorlist{First A.\ Author, Second B.\ Author, Third C.\ Author} which translates to First A. Author, Second B. Author and Third C. Author. Would that work? It would help to also know whether you use the declared "author variables" elsewhere in your document. –  Werner Aug 24 '12 at 19:28
    
I use them in my title page and the abstract page. I defined the surname separate from the first name and middle initial so that the surname will appear first in the abstract page. It would be great though to just write one command to list all authors. How can I do that? –  hpesoj626 Aug 25 '12 at 22:07

@hpesoj626: I've updated my answer with a list processing \listauthors macro. It may come in handy to shorten your usage within your documents. –  Werner Sep 11 '12 at 1:42
