% \section{Introduction}
%
% This file contains the code for the \texttt{newlfont} package
% which provides defines commands like |\rm| to behave as with
% NFSS1, i.e., to change one font attribute without resetting the
% other attributes.

%
%
% \section{The Code}
%
% \begin{macrocode}
%<*package>
% \end{macrocode}
%
% We define the font commands for selecting the typeface. They are
% probably defined by the document class/style but we want to force
% the old meaning from NFSS1.
%
% \changes{v2.2g}{1994/05/11}{DPC Remove definitions of \cs{prm} etc.}
% \begin{macrocode}
\let\rm\rmfamily
\let\sf\sffamily
\let\tt\ttfamily
\let\bf\bfseries
\let\sl\slshape
\let\sc\scshape
\let\it\itshape
% \end{macrocode}
% We also have to define the \emph{emphasize} font change command
% (i.e.\ |\em|). This command will look whether the current font is
% sloped (i.e.\ has a positive |\fontdimen1|) and will then select
% either an upright or italic font.
% \changes{v2.2g}{1994/05/11}{DPC use \cs{DeclareProtectedCommand}}
% \changes{v2.2h}{1994/05/13}{DPC renamed to \cs{DeclareRobustCommand}}
% \begin{macrocode}
\DeclareRobustCommand\em{%
\@nomath\em
\ifdim \fontdimen\@ne\font >\z@\upshape \else \itshape \fi}
% \end{macrocode}
%
% For compatibility with old sources we should define the following
% commands although their use in new documents is discouraged.
% \begin{macrocode}
\let\mediumseries\mdseries
\let\normalshape\upshape
% \end{macrocode}
%
% In case \texttt{newlfont} is used in compatibility mode, eg
%\begin{verbatim}
% \documentstyle[newlfont]{article}
%\end{verbatim}
% or with the \texttt{oldlfont} package already loaded
% we have to undo a number of settings changed by the compatibility
% mode for \LaTeX~2.09 documents.
%
% |\@setfontsize| should not have a |\reset@font| included.
% \changes{v2.2j}{1994/11/06}{Use \cs{@typeset@protect}}
% \begin{macrocode}
\def\@setfontsize#1#2#3{\@nomath#1%
\ifx\protect\@typeset@protect
\let\@currsize#1%
\fi
\fontsize{#2}{#3}\selectfont}
% \end{macrocode}
% Math alphabet identifiers should have an argument.
% \changes{v2.2d}{1994/03/10}{Changed \cs{begingroup}/\cs{endgroup} to
% \cs{bgroup}/\cs{egroup}.}
% \changes{v2.2f}{1994/05/05}{Added saved versions of the
% math-groupers, CAR}
% \begin{macrocode}
\let\math@bgroup\bgroup
\def\math@egroup#1{#1\egroup}
\let \@@math@bgroup \math@bgroup
\let \@@math@egroup \math@egroup
% \end{macrocode}
% Warn again, if text font commands are used in math
% (same macro as in \texttt{lfonts.dtx}).
% \changes{v2.2e}{1994/04/21}{Changed error message}
% \changes{v2.2k}{1995/04/02}{add \cs{noexpand} to second part of message}
% \begin{macrocode}
\def\not@math@alphabet#1#2{%
\relax
\ifmmode
\@latex@error{Command \noexpand#1invalid in math mode}%
{%
Please
\ifx#2\relax
define a new math alphabet^^J%
if you want to use a special font in math mode%
\else
% \end{macrocode}
% We have to add |\noexpand| below to prevent expansion of |#2|. In
% case of |#1| we can omit this (due to the current definition of
% robust commands since they do come out right there :-).
% \begin{macrocode}
use the math alphabet \noexpand#2instead of
the #1command%
\fi
.
}%
\fi}
% \end{macrocode}
%
% In NFSS1 math alphabets had arguments so we have to change |\cal|
% and |\mit| which by default are defined to behave like in
% \LaTeX209.
% \begin{macrocode}
\let\pcal\@undefined
\let\cal\mathcal
\let\pmit\@undefined
\let\mit\mathnormal
% \end{macrocode}
%
% The NFSS1 version of \texttt{newlfont} included the \LaTeX{}
% symbols. And that is probably all there is.
% \begin{macrocode}
\RequirePackage{latexsym}
%</package>
