-\title{PDCFSEL, a font-selection scheme for \TeX}
-\section{Introduction}
-
- This document describes PDCFSEL, a file of font selection macros
- designed to be used with documents using the plain \TeX\ format
- (rather than \LaTeX, for example).
-
- The PDCFSEL macros perform a similar function to the so-called
- New Font Selection Scheme~2 (used in \LaTeX~2e). PDCFSEL uses a
- simpler model of font selection, and so is a smaller
- package---about 110~lines of code---which is just as well as a
- copy of it will probably need to be included with documents
- using it. The description of which fonts are used in a document
- can be relatively compact, despite not using any special
- database files.
-
-\subsec{Organizing fonts into fontsets}
-
- We can arrange the fonts used in an imaginary \TeX\ document in
- a table like so (with an asterisk marking fonts that have to be
- scaled to fit):
- $$\def\*{{\rm*}}
-\vbox{\halign{\strut#\hfil&\quad\vrule#&&\quad\tt#\hfil\cr
- && |\rm|&|\it|&|\bf|&|\bi|&|\mi|&|\sy|\cr
-\noalign{\nointerlineskip}\omit& height \jot\cr
-\noalign{\hrule}\omit& height 1\jot\cr
-\noalign{\nointerlineskip}%
- body text&& cmr10& cmti10& cmbx10& cmbxti10& cmmi10& cmsy10\cr
- footnotes&& cmr8& cmti8& cmbx8& cmbxti10\*& cmmi8& cmsy8\cr
- script&& cmr7& cmti7& cmbx7& cmbxti10\*& cmmi7& cmsy7\cr
- scriptscript&& cmr5& cmti7\*& cmbx5& cmbxti10\*& cmmi5& cmsy5\cr
-\noalign{\nointerlineskip}\omit& height\jot depth\jot&\multispan6\dotfill\cr
-\noalign{\nointerlineskip}%
- heading&& cmss12& cmssi12& -&-&-&-\cr
- subheading&& cmss10& cmssi10& -&-&-&-\cr
-}}
- $$
- The column headings are {\it font nicknames}. These nicknames
- are used as described in the {\it\TeX book} to switch between
- fonts in the same row. Each has a corresponding {\it fam}
- used in maths mode, with symbolic names like |\itfam| and
- |\bffam| (we define $\hbox{|\rmfam|}=0 $ for consistency).
- I~have added nicknames |\mi| and |\sy| for maths italic and
- maths symbol respectively.
-
- Each row of the table is a {\it fontset}. Plain \TeX\ defines a
- single fontset (which is like the `body text' row of this
- table); in Appendix~E, Knuth discusses formats that switch
- between different fontsets with macros like |\ninepoint| and
- |\eightpoint|. \LaTeX~2.09 uses many fontsets, called
- |\normalsize|, |\large|, and so on. (NFSS~2 uses a more complex
- system, where size, weight, and slant may be changed
- independently of each other.)
-
- In this table, subheadings and body text have different fontsets
- in the above, even though the fonts are the same size. Also,
- there are no |\sf| fonts; the headings are printed in sanserif
- by using a fontset with |\rm| mapped on to a sanserif font.
- This is more logical and flexible than the \LaTeX\ approach.
-
- We can call font families which allow this table to work tidily
- `regular', and families (like Computer Modern) that require
- exceptions `irregular'. The above table has one exception
- (|\it| in scriptscript must use a scaled font); the CM Bold
- Extended Text Italic fonts can be described as regular if we
- think of the `body text' entry as being `|cmbxti10 at 10pt|', so
- that the fonts in that column are scaled fonts without
- exception. To make font specification compact, we want to take
- advantage of regular families as much as possible, while not
- making it difficult to include exceptions.
-
-\subsec{Introduction to using PCDFSEL}
-
- PDCFSEL uses no databases of font families, and loads no fonts
- by default. This makes it more flexible, but also requires
- document designers to write a `mini-database' of those fonts
- used in the document. The above scheme might be defined as
- follows:
-\smallskip
-\halign{\indent#\hfil\cr
- |\input pdcfsel|\cr
-\noalign{\smallbreak}%
- |\newfam\bifam|\cr
-\noalign{\smallbreak}%
- |\def\texttemplate{%|\cr
- | \m{rm}{cmr}\m{it}{cmti}\m{bf}{cmbx}\@\m{bi}{cmbxti10}%|\cr
- | \M{mi}{cmmi}\M{sy}{cmsy}%|\cr
- |}|\cr
- |\loadfont\scriptscriptit{cmti7 at 5pt }|\cr
- |\xfontset{scriptscript}\texttemplate{5}|\cr
- |\xfontset{script}\texttemplate{7}|\cr
- |\fontset{note}\texttemplate{8}{10pt}{scriptscript}{scriptscript}|\cr
- |\fontset{body}\texttemplate{10}{12pt}{script}{scriptscript}|\cr
-\noalign{\smallbreak}%
- |\def\headingtemplate{%|\cr
- | \f{rm}{cmss}\f{it}{cmssi}%|\cr
- |}|\cr
- |\fontset{subheading}\headingtemplate{10}{12pt}{subheading}{subheading}|\cr
- |\fontset{heading}\headingtemplate{12}{14pt}{subheading}{subheading}|\cr
-\noalign{\smallbreak}%
- |\bodyfonts|\cr
-}
-\smallbreak
-\noindent
- This defines commands |\bodyfonts|, |\notefonts|,
- |\headingfonts| and |\subheadingfonts| which switch between
- fontsets. (The {\it script} and {\it scriptscript} fontsets,
- which are defined with |\xfontset|, are used only in maths
- mode and don't need `-|fonts|' commands.) These -|fonts|
- commands are not usually used directly in documents;
- |\notefonts| will be used in some |\footnote| command,
- |\headingfonts| in some heading-generating command, and so on.
-
- Changes of fontset are accompanied by changes in parameters like
- |\baselineskip| and pseudo-parameters like |\smallskipamount|,
- and give definitions to the {\it maths font tables}
- |\textfont\rmfam|, \dots, |\scriptscriptfont\syfam| (for those
- fonts that will be used in maths mode).
-
- We want font nickname commands to be efficient, because they
- are expected to be more common than changes between rows in
- the table. In this implementation, after an invocation of
- |\bodyfonts|, the macro |\rm| expands to exactly `|\fam\rmfam
- \bodyrm|'.
-
-\subsec{How the rest of this document is organized}
-
- The remainder of this document is a description of all of
- |pdcfsel.tex|, including more details of how the commands it
- defines are used.
-
- Running this document (|pdcfsel.dtx|) through plain \TeX\
- creates the definitions file (|pdcfsel.tex|) in addition to
- the usual |dvi| and |log| files. This way the macros and
- their documentation may be kept together in one file. The
- definition lines are numbered.
-
- The definitions start with macros for loading individual
- fonts, followed by the macros used to group fonts into
- fontsets.

-%{{{ selecting demand-loading
-
-\section{Selecting auto-loading mode}
-
- The flag |\ifFSELautoload| is true, fonts are auto-loaded when
- they first used instead of all at the start. This is useful
- when not all the fonts described by the fontsets will be
- needed. The flag is set with the user command
- |\autoloadfonts|.
-
- When demand-loading, the fonts used
- are written to a file named after the document with a |.fnt|
- suffix. This checklist might
- be used to decide which fonts need to be sent with the
- document if it is being sent to someone to compile on a
- different \TeX\ system.
-\code
- |\newif\ifFSELautoload

- | \FSELautoloadtrue
- | \csname newwrite\endcsname \FSELfile
- | \immediate\openout\FSELfile=\jobname.fnt
- |}
-\endcode

-%{{{ making csname for one font
-
-\section{How to set up the csname for one font}
-
- The macro |\loadfont| is used to load individual fonts, defining
- a control sequence name (csname) which may be used later to
- switch to that font. When not demand-loading fonts, this is
- just like |\global\font| followed by expanding the
- |\everyloadfont| macro.
-
- If the csname is already defined, then this command does
- nothing. This is so that irregularities in the font scheme for
- the document can be allowed for. Parameter |#1| is the csname,
- for example `|\bodyrm|', and |#2| is the external name, for
- example `|cmr10|' or `|cmr10 at 12pt|'.
-\code
- |\def\loadfont#1#2{%
- | \ifx#1\relax
- | \FSELloadfont#1{#2}%
- | \else\ifx#1\UNDEFINED
- | \FSELloadfont#1{#2}%
- | \fi\fi
- |}
-\endcode
- (We have to compare |#1| against both |\relax|, which is
- produced by |\csname|--|\endcsname|, and a completely undefined
- csname.) The macro |\FSELloadfont| doesa the actual work of
- loading the font.

-\noindent{\it Demand-loading}. We don't load the font, instead we
- define a csname as a macro. When expanded this new macro will
- (a)~write the font name to the |fnt| file; (b)~define the macro
- |\subfont| to load |cmr10| instead (in case \TeX\ stops with a
- `font not loadable' message); (c)~load the font for real (this
- overwrites the macro); (d)~call |\everyloadfont| for per-font
- customization and (e)~switch to the new font.

-
- The macro |\everyloadfont| is expanded immediately after
- actually loading a font. (The definition used is that one
- current when the font is actually loaded, not the one current
- when |\loadfont| was executed.) Its |#1| parameter is always a
- \<fontdef token>, i.e., it can be to used as a parameter to
- |\fontdimen1|. The |#2| parameter is the external name of the
- font.

- might be used to suppress the stretch and

-%{{{ making a fontset
-
-\section{How to set up a fontset}
-
- Now that we know how to define individual font csnames, we
- need the mechanism for grouping them in to fontsets. A
- fontset is defined by a template macro which says what font
- nicknames are defined and gives part of the external font
- name. The template macro takes no parameters and expands to
- a list each of whose elements are of the form
- $$
-\vbox{\halign{$#$\hfil&\quad#\hfil\cr
- \<type> \arg{\<nickname>} \arg{\<partial name>}&
- or\cr
- \cs{@} \<type> \arg{\<nickname>} \arg{\<external name>}&
- for a scaled font.\cr
-}}
- $$
- where a \<type> is one of the control sequences |\f|, |\m| or
- |\M|, and \<nickname> is the two- or three-letter nickname
- used for the font (without any leading backslash), for example
- |rm|, |it|, |bf|. There must be a font fam called
- |\|\<nickname>|fam| (|\rmfam|, |\itfam| etc.\ are already
- defined).
-
- If there is no |\@|, then the \<partial name> is a font name
- sans the size specification, such as |cmr|. The size in
- points will be appended to this (|cmr| + $10\pt$ = |cmr10|).
- If |\@| is included then the \<external name> is the complete
- font name, such as |cmr10| or |ptmr|. This will be followed
- by `{\tt\char32 at\char32 10pt\char32 }', say.
-
- The \<type> specifies how much support for mathematics this font
- requires. This is because maths mode requires that all fonts
- that might be used in a formula be loaded (because the font
- tables |\textfont|, |\scriptfont| and |\scriptscriptfont| must
- be set). The code |\f| means that the font is not used in
- maths, |\m| means that |\textfont| and |\scriptfont| will be set
- correctly for this fam, and |\M| means that |\scriptscriptfont|
- will also be set. In these cases there must be a corresponding
- token ending in `-|fam|' that expands to the fam number.
-
- The fontset name is a sequence of \<letter>s, like `|body|',
- `|note|', `|script|', `|heading|'. This is turned into a
- fontset selection macro by adding `|\|' to the front and
- `|fonts|' to the end (e.g., |\bodyfonts|). The csnames for
- loaded fonts are formed from the fontset name + the nickname
- (e.g., |\bodyrm|).
-
-\subsec{Defining the csnames for a fontset}
-
- The macro |\xfontset| defines all the csnames for the fonts in a
- fontset, without defining a `-|fonts|' macro. This is used to
- define a fontset that is never selected in its own right (e.g.,
- its fonts are used only as subscripts and superscripts), and
- also used internally by the |\fontset| command. Its arguments
- are |#1| the fontset name, |#2| the csname of a template macro,
- and |#3| a \<number> that specifies the font size (sans the
- `|pt|').
-\code
- |\def\xfontset#1#2#3{
- | \def\f##1##2{\expcs\loadfont{#1##1}{##2#3}}
- | \let\m=\f \let\M=\f
- | \def\@##1##2##3{\expcs\loadfont{#1##2}{##3 at #3pt }}
- | #2
- |}
-\endcode
-
-\subsec{Defining a complete fontset}
-
- The user command |\fontset| is used to define a complete
- fontset. Its parameters are
- |#1| (a string of letters) is the fontset name,
- |#2| (a csname) is a template macro,
- |#3| (a \<number>) is size in points,
- |#4| (a \<skip>) is baseline skip,
- |#5| (a fontset name) is the scriptstyle fontset, and
- |#6| (a fontset name) is the scriptscriptstyle fontset.
-\code
- |% Set up a fontset -- define \#1fonts
- |\def\fontset#1#2#3#4#5#6{%
- | \xfontset{#1}{#2}{#3}%
-\endcode
-\begingroup\leftskip=\parindent \advance\leftskip2\fontdimen6\tentt
-\noindent
- Now to define the |\#1fonts| macro. When demand-loading, this
- macro will call |\#1mathfonts| (to ensure the fonts needed for
- maths are loaded). Then it will call |\FSELnicknames| to
- define |\rm|, |\it|, etc., and to define |\textfont\rmfam|, etc.
- Finally it will set the baseline skip and related parameters and
- switch to the new |\rm| font.
-\par\endgroup
-\code
- | \expcs\edef{#1fonts}{%
- | \ifFSELautoload \noexpcs{#1mathsfonts}\fi

-\code
- | \ifFSELautoload
- | \expcs\def{#1mathsfonts}{\FSELloadmaths{#1}{#5}{#6}#2}%
- | \fi
- |}
-\endcode
-
-\subsec{Setting font nicknames}
-
- |\FSELnicknames|
- gives definitions to |\f|, |\m| and |\M| so that expanding the
- template macro defines |\rm| and the like. If the fontset name
- is |ffff|, and a nickname |xx| is introduced with |\f|, the
- macro |\xx| is defined to |\ffffxx|. If it is introduced with
- |\m|, then the font table entries |\textfont\xxfam| and |\scriptfont\xxfam| are also
- set, and |\xx| expands to `|\fam\xxfam \ffffxx|'. If it is
- introduced with |\M| then |\scriptscriptfont\xxfam| is also set.
-
- The parameters are |#1| the fontset name, |#2| the fontset name
- for scriptstyle, and |#3| the fontset name for
- scriptscriptstyle. The implicit fourth parameter is the
- template macro.
-\code
- |\def\FSELnicknames#1#2#3{%
- | \let\@\relax
- | \def\f##1##2{%
- | \expcs\edef{##1}{\noexpcs{#1##1}}%
- | }%
- | \def\m##1##2{%
- | \expcs\textfont{##1fam}\csname#1##1\endcsname
- | \expcs\scriptfont{##1fam}\csname#2##1\endcsname
- | \expcs\edef{##1}{%
- | \fam\expcs\noexpand{##1fam}%
- | \expcs\noexpand{#1##1}%
- | }%
- | }%
- | \def\M##1{%
- | \expcs\scriptscriptfont{##1fam}\csname#3##1\endcsname
- | \m{##1}%
- | }%
- |}
-\endcode
-
-\subsec{Setting the baseline skip}
- The second helper macro, |\setbaselineskip|, sets
- |\baselineskip| and a bunch of related paramaters and
- pseudo-parameters like |\smallskipamount|. It takes one
- parameter, a \<skip>.
-\notepar
- My definitions for the skips that go before and after displays
- put less white\-space around displays than is set in plain \TeX.
- This can be changed by redefining this macro in a style file.
-\endnotepar
-\code
- |\def\setbaselineskip#1{%
- | \baselineskip#1\relax \normalbaselineskip\baselineskip
- | \jot0.25\baselineskip
- | \smallskipamount 0.25\baselineskip plus 0.083\baselineskip
- | minus 0.083\baselineskip
- | \medskipamount 0.5\baselineskip plus 0.167\baselineskip
- | minus 0.167\baselineskip
- | \bigskipamount 1\baselineskip plus 0.333\baselineskip

- | \advance\abovedisplayshortskip-1\abovedisplayskip
- | \belowdisplayskip\medskipamount
- | \belowdisplayshortskip\smallskipamount
- |}
-\endcode
-
-\subsec{Loading maths fonts}
- Finally, we need to force the fonts used in maths at a given
- size to be loaded. for |\f| fonts this does nothing; for |\m|
- fonts it loads the text and script fonts; for |\M| fonts it also
- loads the scriptscript font.
-
- This is done the first time this fontset is selected, even if no
- formulas are used (rather than trying to do something
- complicated like use |\everymath|\dots). Because this macro
- only needs to be used once for each fontset, it finishes by
- redefining |\#1mathfonts| to be the same as |\relax|.
-
- Its parameters are |#1| the fontset name, |#2| the fontset name
- for scriptstyle, and |#3| the fontset name for scriptscriptstyle.
-\code
- |\def\FSELloadmaths#1#2#3{%
- | \let\@\relax \def\f##1##2{}%
- | \def\m##1##2{\csname#1##1\endcsname \csname#2##1\endcsname}%

- | \global\expcs\let{#1mathsfonts}\relax

-\section{Finishing up}
-
- We define |\rmfam|, |\mifam| and |\syfam| as aliases for the
- numbers $0$, $1$ and $2$. This is so that the maths fonts may
- be included in the font templates without any special
- arrangements. The names |\itfam|, |\bffam|, |\ttfam|, and |\slfam| are set in |plain.tex|.
-\code
- |\chardef\rmfam=0 \chardef\mifam=1 \chardef\syfam=2
-\endcode
- Note that we do not include an alias for the the maths
- extension font's fam number. This is because there is only
- one maths extension font---|cmex10|---used for all sizes, so it
- does not belong in any fontset.
