There are many independent variations and features supported by +the \KPfonts{}. This font family can be loaded in plain \TeX{} using +"\input kp-fonts". Macros from \csplain{}~\cite[csplain] are used in this +case. This article describes the main concept of the macros from \csplain{} +which gives fonts support for plain \TeX{} users. A new feature of these +macros (font modifiers) is implemented in \csplain{} from May 2016. + +The section \ref[kpfonts] in this article includes a documentation of +\KPfonts{} if the family is loaded using "\input kp-fonts". This gives an +illustration of power of \csplain{} font support. Finally, section \ref[ffmac] +includes a basic notes for macro programmers. + +Note that all features of \csplain{} macros described here can be used in +all common plain \TeX{} formats: generated by "etex.src" or Knuth's original +plain \TeX{} format or \csplain{}. There is no substantial differences +between them. Of course, \csplain{} preloads a basic set of macros (for +resizing) in its format but if this isn't done then the little set of macros +is read (from \csplain{} package) automatically and additionally. + +\nonum\notoc\sec Contents + +\maketoc + +\sec Font families in \csplain{} macros + +\secc Basics + +The main principle of font macros in \csplain{} is to keep the plain \TeX{} +philosophy. This means: + +\begitems +* use straightforward macros, +* font-files (where a font family is loaded) use directly "\font" primitive, +* leave core font macros for users "\rm", "\bf", and "\it" almost unchanged. +\enditems + +User can set chosen font family by "\input font-file". The ``font-file'' loads +typically four fonts of one family for usage in "\rm", "\bf", "\it" and +"\bi" macros. But the font-file can give more possibilities using ``font +modifiers'' (see bellow). + +The fonts in a font family can be selected by "\rm", "\bf", "\it" and "\bi" +macros. These macros are defined similarly like in plain TeX: + +\begtt +\def\rm{\fam0\tenrm} % in plain TeX: \def\rm{\fam\z@\tenrm} +\def\bf{\fam\bffam \tenbf} % in plain TeX: \def\bf{\fam\bffam\tenbf} +\def\it{\fam\itfam \tenit} % in plain TeX: \def\it{\fam\itfam\tenit} +\def\bi{\fam\bifam \tenbi} % in plain TeX: undefined +\endtt + +The macros above use native font selectors "\tenrm", "\tenbf", "\tenit" and +"\tenbi" declared by "\font" primitive in the font-file. Once these four +selectors are declared, they can be resized to arbitrary size. For example: + +\begtt +\def\sizespec{at12pt}\resizeall +\endtt +% +resizes the font selectors "\tenrm", "\tenbf", "\tenit" and "\tenbi" to 12\,pt +with the same fonts (or with their appropriate optical modifications if they +are available and "\dgsize" is set). The name "\ten.." is here only for +historical reasons and it has nothing to do with real font size selected. For +more information about resizing see the +article \cite[tb-csplain] and comments in the file "csfontsm.tex" where this +feature is implemented. + +User can use +macros "\rm", "\bf", "\it", "\bi"\fnote + {Note that {\tt\string\tentt} is resized too, so {\tt\string\tt} macro can + be used in selected size too. And more font selectors can be resized when + macro programmer registers a font selector for resizing using + {\tt\string\regfont}.} +in a selected size. A more comfortable user environment +for resizing with macros "\typosize", "\typoscale" and "\thefontsize" is +prepared in OPmac macro package \cite[opmac] which is a part of \csplain{} macros too. +The OPmac macros for font resizing set all size-dependent internal parameters and +sizes for math typesetting too. +See section 2 in the OPmac documentation~\cite[opmac-doc]. + +Summary: the meaning of "\tenrm", "\tenbf", "\tenit" and "\tenbi" selectors +depends on context: on a font family chosen by "\input font-file" and on +selected size. + +Users of NFSS from \LaTeX{} may ask: why there isn't a possibility of +independent selectors for ``weight'' and ``shape''? The answer is: We need +not it and we want to keep the plain \TeX{} simplicity. For example OPmac +provides the "\em" macro for emphasizing. It works like "\rm->\it" +"\it->\rm", "\bf->\bi", "\bi->\bf" and it adds the necessary italic +corrections. User can define analogous simple macro if it is needed. + + +\label[fontfam]\secc Prepared font files + +The font-files ready to use are packed to the \csplain{} package. You can +select one line from the following list: + +\begtt +\input lmfotns % Latin Moder fonts + +\input ctimes % Times font family +\input chelvet % Helvetica font family +\input cavantga % AvantGarde font family +\input cbookman % Bookman font family +\input cncent % NewCenturySchlbk font family +\input cpalatin % Palatino font family + +\input cs-termes % TeX Gyre Termes +\input cs-adventor % TeX Gyre Adventor +\input cs-bonum % TeX Gyre Bonum +\input cs-heros % TeX Grye Heros +\input cs-pagella % TeX Gyre Pagella +\input cs-schola % TeX Gyre Schola +\input cs-cursor % TeX Gyre Cursor + +\input cs-antt % Antykwa Torunska +\input cs-polta % Antykwa Poltawskiego + +\input cs-charter % Charter +\input cs-bera % Bera +\input cs-arev % ArevSans +\input cs-libertine % Linux Libertine + +\input kp-fonts % KPfonts +\endtt + +You need not to remember these font-file names.

If modifiers are supported then they are listed in the +"\fontfam" listing. For example "TG Heros" family supports two modifiers +"\cond" and "\caps" which means ``condensed'' and ``caps\&small caps''. +The modifiers can be independently combined but they must be immediately +followed by "\rm", "\bf", "\it", "\bi", "\one" or "\fam" control sequences. + +If the modifiers are followed by "\rm", "\bf", "\it", or "\bi" then a +modification of given basics family variant is selected as a single font. If +they are followed by "\one" then a modification of currently selected variant +is used. If they are followed by "\fam" then it works like "\one" but +moreover, the basic font selectors "\tenrm", "\tenbf", "\tenit" and "\tenbi" +are reloaded using given modifiers, so all family selected by macros "\rm", +"\bf", "\it" and "\bi" works with given modification. Example: + +\begtt +\input cs-heros +{\cond\rm ... Normal condensed.} +{\caps\cond\it ... Caps \& small-caps plus condensed italics.} +{\caps\fam ... Caps \& small-caps, now all basic macros + \rm, \bf, \it, \bi keeps this modification.} +\endtt + +All font selectors and their modifiers do setting locally inside TeX group. +The modifiers keep their data in the \TeX{} memory (locally) and they can be +applied afterwards: + +\begtt +{\cond\fam \rm Here is {\it condensed} font family. + \caps\fam \rm Here is {\it Caps \& small-caps} family which is {\it condensed}.} +\endtt + +This means that "\modifier\something" keeps previously selected +modifications and only adds a new one. + +You can combine fonts from more families. The main principle says: +load the main family last. You can +use "\ffletfont\newselector = {mod+var}{size}" for keeping font selectors from +previous loading. Example: + +\begtt +\input cs-heros +\ffletfont \titlefont = {\cond\bf}{at14pt} % Heros condensed for titles +\input cs-termes % Termes at 10 pt for normal text +\endtt + +If you are using XeTeX or LuaTeX then the U (unicode) encoding is used and +OTF fonts are loaded. You can use "\useff{text}" in such case. This works like +another font modifier and does modification of font-features. Use +"otfinfo -f file.otf" to inspect the font features of used font. Example: + +\begtt +\useff{+onum;+salt}\bf ... use Bold variant with oldstyle digits and + stylistic alternatives +\useff{+onum;+salt}\fam ... use given features for whole family. +\endtt + +\secc Font encodings + +The list printed by "\fontfam" macro shows (in parentheses) what encodings +are supported by each font family. The used abbreviations means: + +\begtt +8t ... 8bit T1 encoding stated in Cork +8z ... 8bit XL2 encoding derived from ISO-8859-2, used in Czech and Slovak TeX +7t ... 7bit encoding declared by Knuth in cmr10 font +U ... Unicode, this means that fonts are loaded in OTF format +\endtt + +\csplain{} format with pdf\TeX{} starts in "8z" encoding by default but this can be +changed to "8t" encoding using "\input t1code". If Xe\TeX{} or LuaTeX is +used then "U" encoding is assumed. If encoding is not set by rules mentioned +right before (i.e. non-\csplain{} with pdf\TeX) then "8t" is set. The +default setting can be changed by "\def\fotenc{enc}" before +"\input font-file". The switching to more various encodings inside document +isn't supported. User can prepare such simply macros if it is needed. + +The "7c" encoding (companion encoding to "8t" with more additional characters) +is provided by "exchars.tex" macro file from \csplain. See this macro +file for more details. The macro file "exchars.tex" is used in +"kp-fonts.tex", thus all additional characters are simply accessible. For +example user write "\euro" and it prints \euro{} when \KPfonts{} are selected (or +when "8z" encoding is used because "8z" encoding includes~\euro{} directly). + +\csplain{} format with pdf\TeX{} provides UTF-8 input encoding unsing +enc\TeX{} extension of pdf\TeX{}. This is documented in \cite[csplain-doc]. +So, user can use accented letters and more characters directly. User can +write {\ttset\rm \euro} and it prints \euro{} in \csplain{} when \KPfonts{} +are selected. Non-\csplain{} formats with +pdf\TeX{} don't provide UTF-8 input unless user creates something for this. +But languages with ISO-8859-1 +characters set (Spanish, French, German, \dots) can use their accented +letters encoded in ISO-8859-1 because this encoding is a subset of "8t" font +encoding. Xe\TeX{} and Lua\TeX{} provides UTF-8 input as native input. + + +\secc Math fonts + +The "\fontfam" macro lists the abbreviation of math fonts collection used +together with selected text font family. See the letters after ``plus sign'' in +the output of "\fontfam[?]" in the section~\ref[fontfam]. + +\begtt +AMS ... AMSTeX font collection: Computer Modern plus a set of others +TX .... TX fonts, they are superset of AMS and designed for Times family +KP .... KP math fonts collection, designed for kpfonts +\endtt + +Note that most of text font families are combined with TX font by default. +The italic and roman variants from selected text font family +is used for variables and for math texts like +sin, lim, max. Other symbols are used from TX fonts collection. + +Two math font macro-selectors are provided: "\normalmath" and "\boldmath". +If a math modifiers are available (this is the case of KP math collection +fonts only) then these math modifiers can be used before "\normalmath" or +"\boldmath". These selectors sets the fonts for whole formula inside math +mode. On the other hand, you can use individual math switchers which selects +a math alphabet inside math mode: "\cal" for simple calliraphic, "\script" +for more calligraphic, "\frak" for fraktur and "\bbchar" for double strokes. +Of course, "\rm" and "\it" select normal or italics. But "\bf" and "\bi" +select {\em sans serif} bold and bold-italic, because it is more +conventional to use sans serifed bold in math formulas (for vectors or +matrices, for example). + +\csplain{} package inclues macros for math font collections in the +following files + +\begtt +ams-math.tex ... AMS fonts +tx-math.tex ... TX fonts +ntx-math.tex ... NTX fonts +kp-math.tex ... KP fonts +\endtt +% +These files provide simple loading of math fonts collections including +scaling of the whole collection to desired sizes. Basic features are +documented in these files directly. + +A different math font collection can be combined with text font +family than default. It can be done by "\let\loadmathfonts=\relax" before "\input font-file". +This suppresses the loading of math font family. Then "\input foo-math" can +be used directly. + +You can copy and rename a "foo-math.tex" file and you can do various +modifications or set a complete new math fonts collection. + +\label[kpfonts]\sec The \KPfonts{} manual for plain \TeX{} + +Use "\input kp-fonts".
