It +% contains the declaration of the standard text encodings used at the +% site as well as a minimal subset of font shape groups that NFSS will +% look at to ensure that the specified encodings are valid. +% +% The math part contains the setup for math encodings as well as the +% default math symbol declarations that belong to the encoding. +% +% It is possible to change this setup (by using other fonts, or +% defaults) without losing the ability to +% process documents written at other sites. Portability in this sense +% means that a document will compile without errors. It does not mean, +% however, that identical output will be produced. For this it is +% necessary that the distributed setup is used at both installations. +% +% \section{Customization} +% +% You are not allowed to change this source file! If you want to +% change the default encodings and/or the font shape groups preloaded +% you should should create a copy of \texttt{fonttext.ltx} +% under the name \texttt{fonttext.cfg} and change this copy. If +% \LaTeXe{} finds a file of this name it will use it, otherwise it +% uses the standard file which is \texttt{fontdef.ltx}. +% +% If you don't plan to use Computer Modern much or at all, it might +% (!) be a good idea to make your own \texttt{fonttext.cfg}. Look at +% the comments below (docstrip module `text') to see what should +% should go into such a file. +% +% To change the math font setup use a copy of \texttt{fontmath.ltx} +% under the name \texttt{fontmath.cfg} and change this copy. However, +% dealing with this interface is even more a job for an expert than +% changing the text font setup --- in short, we don't encourage either. +% +% \begin{quote} +% \textbf{Warning:} please note that we don't support customised +% \LaTeX{} versions. Thus, before sending in a bug report please try +% your test file with a \LaTeX{} format which is not customised and +% send in the log from that version (unless the problem goes away). +% \end{quote} +% +% Please note: the following standard encodings have to +% be defined in all local variants of \texttt{font....cfg} to guarantee +% that all \LaTeX{} installations behave in the same way. +% \begin{center} +% \begin{tabular}{ll} +% |T1| & Cork \TeX{} text encoding \\ +% |OT1| & old \TeX{} text encoding \\ +% |U| & unknown encoding \\ +% |OML| & old \TeX{} math letters encoding \\ +% |OMS| & old \TeX{} math symbols encoding \\ +% |OMX| & old \TeX{} math extension symbols encoding +% \end{tabular} +% \end{center} +% Notice that some of these encodings are `old' in the sense that we +% hope that they will be superseded soon by encoding standards defined +% by the \TeX{} user community. Therefore this set of default encodings +% may change in the future. +% +% The first candidate is |OT1| which will soon be replaced by |T1|, the +% official \TeX{} text encoding. +% +% \begin{quote}\textbf{Warning:} +% If you add additional encodings to this file there is no guarantee +% any longer that files processable at your installation will also be +% processable at other installations. Thus, if you make use of +% such an encoding in your document, e.g.~if you intend to typeset in +% Cyrillic (|OT2| encoding), you need to specify this encoding in the +% preamble of your document prior to sending it to another +% installation. Once the encoding is specified in that place in your +% document, the document is processable at all \LaTeX{} installations +% (provided they have suitable fonts installed). +% +% For this reason we suggest that you define a short package file that +% sets up an additional encoding used at your site (rather than +% putting the encoding into this file) since this package can easily +% be shipped with your document. +% \end{quote} +% +% +% \StopEventually{} +% +% \section{The \texttt{docstrip} modules} +% +% The following modules are used to direct \texttt{docstrip} in +% generating external files: +% \begin{center} +% \begin{tabular}{ll} +% driver & produce a documentation driver file \\ +% text & produce the file \texttt{fonttext.ltx}\\ +% math & produce the file \texttt{fontmath.ltx}\\ +% cfgtext & produce a dummy \texttt{fonttext.cfg} file\\ +% cfgmath & produce a dummy \texttt{fontmath.cfg} file\\ +% \end{tabular} +% \end{center} +% A typical \texttt{docstrip} command file would then have entries like: +% \begin{verbatim} +%\generateFile{fonttext.ltx}{t}{\from{fontdef.dtx}{text}} +%\end{verbatim} +% +% +% \section{A driver for this document} +% +% The next bit of code contains the documentation driver file for +% \TeX{}, i.e.~the file that will produce the documentation you are +% currently reading. It will be extracted from this file by the +% \dst{} program. +% \begin{macrocode} +%<*driver> +\documentclass{ltxdoc} +\GetFileInfo{fontdef.dtx} +\begin{document} + \DocInput{fontdef.dtx} +\end{document} +% +% \end{macrocode} +% +% +% +% \section{The \texttt{fonttext.ltx} file} +% +% The identification is done earlier on with a |\ProvidesFile| +% declaration. +% \begin{macrocode} +%<*text> +\typeout{=== Don't modify this file, use a .cfg file instead ===^^J} +% \end{macrocode} +% +% \subsection{Encodings} +% +% This file declares the standard encodings for text and math +% fonts. All others should be declared in packages or in the +% documents directly. +% +% For every text encoding there are normally a number of encoding +% specific commands, e.g.~accents, special characters, etc. (The +% definition for such a command might have to change when the +% encoding is changed, because the character is in a different +% position, or not available at all, or the accent is produced in a +% different way.) This is handled by a general mechanism which is +% described in \texttt{ltoutenc.dtx}. +% +% By convention, text encoding specific declarations, including the +% declaration |\DeclareFontEncoding|, are kept in separate file of +% the form \meta{enc}\texttt{enc.def}, e.g.~\texttt{ot1enc.def}. This +% allows other applications to make use of the declarations as +% well. +% +% Similar to the default encoding, the loading of the encoding +% files for the two major text encodings shouldn't be changed. +% In particular, the \texttt{inputenc} package depends on this. +% \changes{v2.2s}{1997/12/20}{Added documentation} +% +% \changes{v2.1d}{1994/01/05}{Removed nf prefix from file names.} +% \changes{v2.1f}{1994/05/14}{Removed .def files.} +% \changes{v2.1g}{1994/05/1g}{Removed \cs{DeclareFontEncoding} for ot1 +% and t1 and input .def files instead} +% \changes{v2.2c}{1994/10/25}{Added OMSenc.def} +% \changes{v2.2d}{1994/10/31}{Added OMLenc.def ...} +% \changes{v2.2e}{1994/10/31}{... and moved further down} +% \changes{v2.2f}{1994/11/07}{(DPC) Updated to use \cs{ProvidesFile}} +% \changes{v2.2h}{1994/11/16}{(DPC) Removed \cmd\{ and \cmd\}} +% \begin{macrocode} +\input {omlenc.def} +\input {t1enc.def} +\input {ot1enc.def} % <- should come after T1 for speed +\input {omsenc.def} +% \end{macrocode} +% +% We then set set the default text font encoding. This will +% hopefully change some day to |T1|. This setting should \emph{not} +% be changed to produce a portable format. +% \begin{macrocode} +\fontencoding{OT1} +% \end{macrocode} +% +% If different encodings for text fonts are in use one could put +% the common setup into |\DeclareFontEncodingDefaults|. There is +% now a better mechanism so using this interface is discouraged! +% \begin{macrocode} +\DeclareFontEncodingDefaults{}{} +% \end{macrocode} +% +% Then we define the default substitution for every encoding. +% This release of \LaTeXe{} assumes that the ec fonts are +% available. It is possible to change this to point to some other +% font family (e.g., Times with the appropriate encoding if it is +% available) without making documents non-portable. However, in +% such a case documents will produce different page breaks at other +% sites. The substitution defaults can all be changed without +% losing portability as long as there are font shape definitions +% for the selected substitutions. +% \begin{macrocode} +\DeclareFontSubstitution{T1}{cmr}{m}{n} +\DeclareFontSubstitution{OT1}{cmr}{m}{n} +% \end{macrocode} +% +% For every encoding declaration, \LaTeXe{} will try to verify that +% the given substitution information makes sense, i.e.~that it is +% impossible to go into an endless loop if font substitution +% happens. This is done at the moment the |\begin{document}| is +% encountered. \LaTeXe{} will then check that for every encoding the +% substitution defaults form a valid font shape group, which means +% that it will check if there is a |\DeclareFontShape| declaration +% for this combination. We will therefore load the corresponding +% |.fd| files now. If we don't do this they would be loaded at +% verification time (i.e.~at |\begin{document}| which would delay +% processing unnecessarily. +% +% \begin{quote} +% \textbf{Warning:} Please note that this means that you have to +% regenerate the format whenever you change any of these +% \texttt{.fd} files since \LaTeXe{} will not read \texttt{.fd} +% files if it already knows about the encoding/family +% combination. +% \end{quote} +% +% \changes{v2.2m}{1995/11/01}{add \cs{nfss@catcodes} for internal/1932} +% The |\nfss@catcodes| ensures that white space is ignored in any +% definitions made in the fd files. +% \begin{macrocode} +\begingroup +\nfss@catcodes +\input {t1cmr.fd} +\input {ot1cmr.fd} +\endgroup +% \end{macrocode} +% +% We also load some other font definition files which are normally +% needed in a document. This is only done for processing speed and +% you can comment the next two lines out to save some memory. If +% necessary these files are then loaded when your document is +% processed. (Loading |.fd| files is a less drastic step compared +% to preloading fonts because the number of fonts is limited 255 at +% (nearly) every \TeX{} installation, while the amount of main memory +% is not a limiting factor at most installations.) +% +% \begin{macrocode} +\begingroup +\nfss@catcodes +\input {ot1cmss.fd} +\input {ot1cmtt.fd} +\endgroup +% \end{macrocode} +% +% Even with all the precautions it is still possible that NFSS will +% run into problems, for example, when a |.fd| file contains +% corrupted data. To guard against such cases NFSS has a very +% low-level fallback font that is installed with the following line. +% \begin{macrocode} +\DeclareErrorFont{OT1}{cmr}{m}{n}{10} +% \end{macrocode} +% This means, ``if everything else fails use Computer Modern Roman +% normal shape at 10pt in the old text encoding''. +% You can change the font used but the encoding should be the same +% as the one specified with |\fontencoding| above. +% +% +% \subsection{Defaults} +% +% To allow the use of |\rmfamily|, |\sffamily|, etc.\ in documents +% even if non-standard families are used we provide nine macros +% which hold the name of the corresponding families, series, and so +% on. This makes it easy to use other font families (like Times +% Roman, etc.). One simply has to redefine these defaults. +% +% All these hooks have to be defined in this file but you can +% change their meaning (except for |\encodingdefault|) without +% making documents non-portable. +% +% +% \begin{macro}{\rmdefault} +% \begin{macro}{\sfdefault} +% \begin{macro}{\ttdefault} +% The following three definitions set up the meaning for +% |\rmfamily|, |\sffamily|, and |\ttfamily|. +% \begin{macrocode} +\newcommand\rmdefault{cmr} +\newcommand\sfdefault{cmss} +\newcommand\ttdefault{cmtt} +% \end{macrocode} +% \end{macro} +% \end{macro} +% \end{macro} +% +% \begin{macro}{\bfdefault} +% \begin{macro}{\mddefault} +% Series changing commands are influenced by the following hooks. +% \begin{macrocode} +\newcommand\bfdefault{bx} +\newcommand\mddefault{m} +% \end{macrocode} +% \end{macro} +% \end{macro} +% +% \begin{macro}{\itdefault} +% \begin{macro}{\sldefault} +% \begin{macro}{\scdefault} +% \begin{macro}{\updefault} +% Shape changing commands use the following hooks. +% \begin{macrocode} +\newcommand\itdefault{it} +\newcommand\sldefault{sl} +\newcommand\scdefault{sc} +\newcommand\updefault{n} +% \end{macrocode} +% \end{macro} +% \end{macro} +% \end{macro} +% \end{macro} +% +% \begin{macro}{\encodingdefault} +% \begin{macro}{\familydefault} +% \begin{macro}{\seriesdefault} +% \begin{macro}{\shapedefault} +% Finally we have the hooks that describe the behaviour of +% the |\normalfont| command. To stay portable, the definition of +% |\encodingdefault| should \emph{not} be changed and should match +% the setting above for |\fontencoding|. All other values can be +% set according to your taste. +% \begin{macrocode} +\newcommand\encodingdefault{OT1} +\newcommand\familydefault{\rmdefault} +\newcommand\seriesdefault{\mddefault} +\newcommand\shapedefault{\updefault} +% \end{macrocode} +% \end{macro} +% \end{macro} +% \end{macro} +% \end{macro} +% +% +% This finishes the low-level setup in \texttt{fonttext.ltx}. +% \begin{macrocode} +% +% \end{macrocode} +% +% +% +% +% \section{The \texttt{fontmath.ltx} file} +% +% The identification is done earlier on with a |\ProvidesFile| +% declaration. +% \begin{macrocode} +%<*math> +\typeout{=== Don't modify this file, use a .cfg file instead ===^^J} +% \end{macrocode} +% +% \subsection{The font encodings used} +% +% \begin{macrocode} +\DeclareFontEncoding{OML}{}{} +\DeclareFontEncoding{OMS}{}{} +\DeclareFontEncoding{OMX}{}{} +% \end{macrocode} +% Finally a declaration for |U| encoding which serves for all fonts +% that do not fit standard encodings. For math this sets up +% |\noaccents@| providing for AMS-\LaTeX{}. This macro is used +% therein to handle accented characters if they are not supported +% by the font. In other words, if fonts with |U| encoding are used +% in math, all accents (like from |\breve|) are obtained from some +% other font that has them. +% \begin{macrocode} +\DeclareFontEncoding{U}{}{\noaccents@} +% \end{macrocode} +% The encodings for math are next: +% \begin{macrocode} +\DeclareFontSubstitution{OML}{cmm}{m}{it} +\DeclareFontSubstitution{OMS}{cmsy}{m}{n} +\DeclareFontSubstitution{OMX}{cmex}{m}{n} +\DeclareFontSubstitution{U}{cmr}{m}{n} +% \end{macrocode} +% +% \begin{macrocode} +\begingroup +\nfss@catcodes +\input {omlcmm.fd} +\input {omscmsy.fd} +\input {omxcmex.fd} +\input {ucmr.fd} +\endgroup +% \end{macrocode} +% +% \subsubsection{Symbolfont and Alphabet declarations} +% +% We now define the basic symbol fonts used by \LaTeX{}. +% These four symbol fonts must be defined by this file. +% +% It is possible to make the symbol fonts point to other external +% fonts without losing the ability to process documents written +% at other sites, as long as one defines the same symbol font names +% with the same encodings, e.g.~|operators| with |OT1| etc. +% If other encodings are used documents become non-portable. +% Such a change should therefore be done in a package file. +% +% \changes{v2.1e}{1994/01/19}{Added missing setting for symbols in +% bold version.} +% \begin{macrocode} +\DeclareSymbolFont{operators} {OT1}{cmr} {m}{n} +\DeclareSymbolFont{letters} {OML}{cmm} {m}{it} +\DeclareSymbolFont{symbols} {OMS}{cmsy}{m}{n} +\DeclareSymbolFont{largesymbols}{OMX}{cmex}{m}{n} +% \end{macrocode} +% +% \begin{macrocode} +\SetSymbolFont{operators}{bold}{OT1}{cmr} {bx}{n} +\SetSymbolFont{letters} {bold}{OML}{cmm} {b}{it} +\SetSymbolFont{symbols} {bold}{OMS}{cmsy}{b}{n} +% \end{macrocode} +% +% Below are the seven math alphabets which are defined by NFSS. +% Again they must be defined by this file. +% However, as before you can change the fonts used without losing +% portability, but you should be careful when changing the encoding +% since that may make documents come out wrong. +% \begin{macrocode} +\DeclareSymbolFontAlphabet{\mathrm} {operators} +\DeclareSymbolFontAlphabet{\mathnormal}{letters} +\DeclareSymbolFontAlphabet{\mathcal} {symbols} +\DeclareMathAlphabet {\mathbf}{OT1}{cmr}{bx}{n} +\DeclareMathAlphabet {\mathsf}{OT1}{cmss}{m}{n} +\DeclareMathAlphabet {\mathit}{OT1}{cmr}{m}{it} +\DeclareMathAlphabet {\mathtt}{OT1}{cmtt}{m}{n} +% \end{macrocode} +% Given the currently available fonts we cannot bold-en |\mathbf| +% and |\mathtt| but in principle one could use `ultra bold' or +% something.
