% \bigskip
% The purpose of this package is to provide substitutes of polish
% national characters built using only old fonts (OT1). Besides of
% producing characters missing from OT1 this package takes care of
% less obvious matter: OT1 is not a really well-defined encoding since
% typewritter fonts differ from others in some positions.
%
% The package is loaded in the standard way with the
% |\usepackage{ot1patch}| command.

% Since I hate the presence of section `Printing the documentation' in

% documentation LaTeX this file. If you need to change the driver run
% DOCSTRIP and ask it to make ogonek.drv by stripping ogonek.dtx with
% option `driver'. Do *not* modify this file.

% \subsection{Identification}
% We start the code with standard identification of the package
% \begin{macrocode}
%<*package>
\NeedsTeXFormat{LaTeX2e}[1994/12/01]
\ProvidesPackage{ot1patch}[\filedate\space\fileversion\space
A patch for some OT1 characters (MW)]
% \end{macrocode}
%
% \subsection{The \texttt{\string\k} macro (polish ogonek)}
% This comes from L.~Holenderski's \texttt{plfonts.sty}.
% Positioning of ogonek for specific letters is tuned for 300dpi
% Computer Modern fonts, but works reasonably well with other
% resolutions.
%
% Ogonek is made from half-circle used by \TeX\ to produce
% $\hookrightarrow$.
% \begin{macro}{\@sob}
% Macro |\@sob| positioning ogonek under a letter. Parameters are
% letter and fractions hl,ho,vl,vo.
% \begin{macrocode}
\dimendef\pl@left=0 \dimendef\pl@down=1
\dimendef\pl@right=2 \dimendef\pl@temp=3
\def\@sob#1#2#3#4#5{%
\setbox0\hbox{#1}\setbox1\hbox{$_\mathchar'454$}\setbox2\hbox{p}%
\pl@right=#2\wd0 \advance\pl@right by-#3\wd1
\pl@down=#5\ht1 \advance\pl@down by-#4\ht0
\pl@left=\pl@right \advance\pl@left by\wd1
\pl@temp=-\pl@down \advance\pl@temp by\dp2 \dp1=\pl@temp
\leavevmode
\kern\pl@right\lower\pl@down\box1\kern-\pl@left #1}
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\@iIuUogonek}
% \begin{macro}{\k}
% Here is the |\k| default macro (it is not normally defined in OT1), with
% special positioning of ogonek for some letters. We don't do this with
% |\DeclareTextCompositeCommand| because it wouldn't fit with the defaults
% mechanism.
% \begin{macrocode}
\def\@iIuUogonek#1{%
\ifx i#1\@sob i{.66}{.20}{0}{.90}\else
\ifx I#1\@sob I{.80}{.50}{0}{.90}\else
\ifx u#1\@sob u{.66}{.20}{0}{.90}\else
\ifx U#1\@sob U{.60}{.35}{0}{.90}\else
\@sob {#1}{.50}{.35}{0}{.90}\fi
\fi \fi \fi
}
\DeclareTextCommandDefault\k[1]{%
\ifx a#1\@sob a{.66}{.20}{0}{.90}\else
\ifx A#1\@sob A{.80}{.50}{0}{.90}\else
\ifx e#1\@sob e{.50}{.35}{0}{.93}\else
\ifx E#1\@sob E{.60}{.35}{0}{.90}\else
\@iIuUogonek{#1}%
\fi \fi \fi \fi
}
% \end{macrocode}
% \end{macro}
% \end{macro}
%
% \subsection{Polish crossed l}
% Since in typewritter fonts there is no cross character for polish \l\ we
% will have to take special actions then. For that purpose we define the
% next macro. It performs a rather devious check if the font in use is
% `typewritter like'. Regular text fonts contain in position '40 the cross
% for polish \l, but in typewritter `visible space' occurs there. Second
% of these characters has positive depth, contrary to the first, so we
% check for that. This is slow, better check is welcome.
%
% \begin{macrocode}
\def\if@ttfont#1#2{\setbox0=\hbox{\char'40}\ifdim\dp0>0pt#1\else#2\fi}
% \end{macrocode}
%
% \begin{macro}{\@spb}
% This definition is used to cross l or L in typewritter fonts.
% \changes{0.2}{1997/06/07}{Added leavevmode}
% \begin{macrocode}
\def\@spb#1#2#3#4#5{%
\setbox0\hbox{#1}\setbox2\hbox{\char'023}%
\pl@right=#2\wd0 \advance\pl@right by-#3\wd2
\pl@down=#5\ht2 \advance\pl@down by-#4\ht0
\pl@left=\pl@right \advance\pl@left by\wd2
\ht2=\pl@down \dp2=-\pl@down
\leavevmode
\kern\pl@right\lower\pl@down\box2\kern-\pl@left #1}
% \end{macrocode}
% \end{macro}
%
% And here are definitions of |\l| and |\L|. Unfortunately we have
% to redefine \LaTeX's values.
% \begin{macrocode}
\DeclareTextCommand\l{OT1}{%
\if@ttfont{\@spb l{.45}{.5}{.4}{.8}}%
{{\char32l}}}
\DeclareTextCommand\L{OT1}{%
\if@ttfont{\@spb L{.23}{.5}{.4}{.8}}%
{\leavevmode\setbox0\hbox{L}\hbox to\wd0{\hss\char32L}}}
% \end{macrocode}
%
% \subsection{Dot accent}
% \begin{macro}{\@skb}
% \changes{0.2}{1997/06/07}{Added leavevmode}
% Typewritter fonts don't contain the dot accent so we use raised
% period instead. As this style is prepared with polish language
% in mind, this is done for \.z only.
% \begin{macrocode}
\def\@skb#1#2#3#4#5{%
\setbox0\hbox{#1}\setbox1\hbox{\char'056}%
\pl@right=#2\wd0 \advance\pl@right by-#3\wd1
\pl@down=#5\ht1 \advance\pl@down by-#4\ht0
\pl@left=\pl@right \advance\pl@left by\wd1
\leavevmode
\kern\pl@right\lower\pl@down\box1\kern-\pl@left #1}
% \end{macrocode}
% \end{macro}
%
% And appropriate redefinition for |\.|:
% \begin{macrocode}
\DeclareTextCompositeCommand\.{OT1}z{%
\if@ttfont{\@skb z{.5}{.5}{1.2}{0}}%
{{\accent'137z}}}
\DeclareTextCompositeCommand\.{OT1}Z{%
\if@ttfont{\@skb Z{.5}{.5}{1.1}{0}}%
{{\accent'137Z}}}
% \end{macrocode}
%
% \subsection{French quotes
% (\guillemotleft guillemotes\guillemotright)}
% \changes{0.2}{1997/06/18}{Added \cs{leavevmode}}
% Here is the best substitute for guillemotes we could think of.
% \begin{macrocode}
\DeclareTextCommandDefault\guillemotleft
{\leavevmode\raise.3ex
\hbox{$\scriptscriptstyle\langle\!\langle$}}
\DeclareTextCommandDefault\guillemotright
{\leavevmode\raise.3ex
\hbox{$\scriptscriptstyle\rangle\!\rangle$}}
% \end{macrocode}
%
% And that's all.
