\title{Building latin smallcaps letters}
\author{Lars Hellstr\"om}
\date{3 January 2003}

\begin{document}
\maketitle

This file contains commands that build some proper small capital 
glyphs from other small capital glyphs, but nothing is done is those 
base glyphs have not already been set.

If you want to \emph{fake} small capitals using full capitals, then 
have a look at \texttt{lsfake.mtx} instead.

\setcommand\setcsctopglyph#1#2#3#4{
   \ifareglyphs{#2small,#3}\then
      \setglyph{#1}
         \topaccent{#2small}{#3}{#4}
      \endsetglyph
      \setleftrightkerning{#1}{#2small}{1000}
   \Fi
}
\setcommand\setcscbotglyph#1#2#3#4{
   \ifareglyphs{#2small,#3}\then
      \setglyph{#1}
         \botaccent{#2small}{#3}{#4}
      \endsetglyph
      \setleftrightkerning{#1}{#2small}{1000}
   \Fi
}
\begincomment\medskip
A \textbf{Try: Set glyph} is an ordinary \textbf{Set glyph} which is 
conditional on that a set of glyphs (those used to construct the 
composite glyph) are available. It is technically e.g.
\begin{quotation}
  \setcsctopglyph{\macroparameter{1}}{\macroparameter{2}}%
    {\macroparameter{3}}{\macroparameter{4}}
  \setcscbotglyph{\macroparameter{1}}{\macroparameter{2}}%
    {\macroparameter{3}}{\macroparameter{4}}\par
\end{quotation}
(both of which are implemented in the code as simple four argument 
commands), but in the list of commands below those two commands will 
be typeset as
\resetcommand\setcsctopglyph#1#2#3#4{%
   \Aheading{Try: Set glyph `\TypesetStringExpression{#1}'}
   \topaccent{#2small}{#3}{#4}
   \setleftrightkerning{#1}{#2small}{1000}
}
\resetcommand\setcscbotglyph#1#2#3#4{%
   \Aheading{Try: Set glyph `\TypesetStringExpression{#1}'}
   \botaccent{#2small}{#3}{#4}
   \setleftrightkerning{#1}{#2small}{1000}
}
\begin{quotation}
  \setcsctopglyph{\macroparameter{1}}{\macroparameter{2}}%
    {\macroparameter{3}}{\macroparameter{4}}
  \setcscbotglyph{\macroparameter{1}}{\macroparameter{2}}%
    {\macroparameter{3}}{\macroparameter{4}}
\end{quotation}

\subsection{Getting the \textit{smallcapsscale} right}

The \textit{smallcapsscale} integer is normally only used when 
faking smallcaps by shrinking capitals, but with one of the 
glyphs below (\texttt{Lcaron}) it is actually used for shrinking 
the right quote. Thus a suitable default value has to be assigned 
to it.
\endcomment

\ifareglyphs{L,Lsmall}\then
   \setint{smallcapsscale}{
     \div{\mul{1000}{\height{Lsmall}}}{\height{L}}
   }
\Else
   \setint{smallcapsscale}{800}
\Fi

\begincomment
\subsection{Accenting smallcaps glyphs}

The commands below build accented smallcaps letters from existing 
smallcaps letters and normal accents. The accent positions are the 
ones traditionally used in \texttt{latin.mtx}.

\endmetrics

\texttt{Dbar} and \texttt{Dbarsmall} are old names for this glyph; 
nowadays the standard names are rather \texttt{Dcroat} and 
\texttt{Dcroatsmall}, but using those names throughout would require 
a coordinated change of the ETX files.
It is probably possible to build a decent \texttt{Dbarsmall} from 
\texttt{Dsmall} and an \texttt{lslashslash} (or the like), similarly 
to the case with \texttt{dbar}, but that would require some 
experimentation.

\section{Changes}

This file was created 2003/01/02--05. It is loosely based on parts 
of \texttt{latin.mtx}. (LH)

2003/02/06: Added setting of \textit{smallcapsscale}, and made 
\texttt{Lcaron} kern like \texttt{L} only on the left (not on the 
right). (LH)
