% \maketitle
%
% This little package is mainly meant to be used
% when there is a (TrueType or OpenType) font
% that does not provide real small capitals.
% Some tend to use uppercased letters
% as a workaround -- it is a bad workaround!
% In fact, I consider it better practice
% to borrow, or steal the small capitals from another font.
% And this is exactly what the package does.
% This might also be useful in the rare case
% that someone does not like the present
% small capitals, and wants to change them,
% or likes those from another font better.
%
% However, to achieve the borrowing one does only need to load the package
% and specify the name of the target font via the \option{from} option:
%
% |\usepackage|[\option{from}=\(\langle\)\textit{font name}\(\rangle\)]\{stealcaps\}
%
% It works with both pdf\LaTeX and its successors Xe\LaTeX{} and Lua\LaTeX.
% In the first case you have to make sure the font name is NFSS compliant.
% Otherwise, it has to be \pkg{fontspec} compliant.
%
% \StopEventually{}
%
% The implementation is rather simple and straightforward.
%
% As usual, we start by loading what is required:
%
% \begin{macrocode}
\RequirePackage{pgfopts}
\RequirePackage{iftex}
% \end{macrocode}
%
% We have to load \pkg{fontspec} in case Xe\LaTeX or Lua\LaTeX,
% hence not pdf\LaTeX is in use, to make sure the |\fontspec| command,
% used by this package, is guarantied to be defined.
%
% \begin{macrocode}
\ifPDFTeX\else
\RequirePackage{fontspec}
\fi
% \end{macrocode}
%
% Then we set up the only package option
% and commence its processing.
%
% \begin{macrocode}
\pgfkeys{
/stc/.cd,
from/.store in=\font@wildcard@stc
}
\ProcessPgfOptions{/stc}
% \end{macrocode}
%
% To distinguish between the operating engines
% there are two macros to select the replacement font
% (one for \pkg{fontspec} powered ones
% and one for good old pdf\LaTeX),
% which then are |\let| to |\font@stc|
% according to the engine in use.
%
% \begin{macrocode}
\def\font@xe@or@lua@stc{\fontspec}
\def\font@pdf@stc{\fontfamily}
\def\selectfont@or@relax@stc{\relax}
\ifPDFTeX
\let\font@stc\font@pdf@stc
\let\selectfont@or@relax@stc\selectfont
\else
\let\font@stc\font@xe@or@lua@stc
\fi
% \end{macrocode}
%
% At last, we load the replacement font
% employing |\font@stc| inside a group
% and substitute the small captials fonts.
%
% \begin{macrocode}
\begingroup
\font@stc\font@wildcard@stc\selectfont@or@relax@stc
\DeclareFontShape{\f@encoding}{\rmdefault}{m}{sc}{%
<-> ssub * \f@family/m/sc
}{}
\DeclareFontShape{\f@encoding}{\rmdefault}{bx}{sc}{%
<-> ssub * \f@family/bx/sc
}{}
\endgroup
% \end{macrocode}
