The circumstances are +favorable enough. Up to now, though, we were missing one tool. + +Here is the problem: you want to substitute a character in the +DC font by some special character you need in your target language. +OK. How to construct the virtual representation for this character? +well, for that we have Eberhard Mattes' {\tt QDTeXVPL}. It will give us +the description of all characters we need. Now suppose you replace +an `A' with some accent, by an `E' with some other accent. What +about all the kerning pairs involving that `A' you took away? +And what all those new kerning pairs you need for the `E'? + +Do you want to replace the old kerning pairs by new ones, by +hand?? well, you can try; but if you ever attempt to take a +coffee break, then you will never be able to recognize again what +you have changed, and what remains to be changed. Not to mention +the nasty habit of PL files of having kerning pairs applying to +more than one characters. This optimizes parsing speed, but surely +makes it more difficult to make manual changes. + +The utility I'm presenting does all this automatically. It will +read a {\tt [V]PL} file and will +\begin{itemize} +\item remove all kerning pairs involving removed characters; +\item introduce kernng pairs for new characters; +\item add or remove ligatures. +\end{itemize} + +To illustrate the use of this program, I provide a real-world +example, namely a virtual font for Esperanto. You will follow the +whole process of giving birth to this font, starting by its +mother: the common {\tt dcr10} font. + +\section{How it works} + +{\tt AdjKerns} has been written in ANSI~C\footnote{Be aware! +its author is a lousy C programmer, so {\em don't} trust the +program as you trust \TeX. Keep a critical eye for possible +bugs, and report them!}. It should run everywhere; it has been +tested on a Macintosh (MPW~3.2 and Think C~5.0). + +The command line should look like this: + +\begin{verbatim} +AdjKerns [-c foo.kcf] [-o <something>] <input file> +\end{verbatim} + +The input file is a {\tt PL} or a {\tt VPL} file\footnote{If +you look closer you'll see that there is no big difference; +the latter has a few more possibilities, otherwise the +syntax is the same.}. Out of this file {\tt AdjKerns} will +read only the {\tt LIGTABLE}, the rest will remain untouched. + +The rules on how to modify the {\tt LIGTABLE} are read +from the configuration file {\tt foo.kcf}. This file is +optional; if you don't include any rules, then {\tt AdjKerns} +will just rewrite your {\tt [V]PL} file, by ignoring any +optimization attempts of the {\tt LIGTABLE}. The file will be +bigger, but the result will be the same; it will be easier to +modify, though. + +The {\tt-o} option specifies the output file. If no such is +specified, then the input file is overwritten (you don't need +that file anyway\ldots). + +Let's see now the syntax of the {\tt KCF} file. The following +lines are allowed: + +\verb=KERN <char> LIKE <char>= + +\verb=KERN <char> LEFT LIKE <char>= + +\verb=KERN <char> RIGHT LIKE <char>= + +\verb=KERN <char> LEFT LIKE <char> RIGHT LIKE <char>= + +\verb=UNKERN <char>= + +\verb=ADD <lig> <char> <char> -> <char>= + +\verb=ADD <lig> BOUNDARYCHAR <char> -> <char>= + +\verb=REMOVE <lig> <char> <char> -> <char>= + +\verb=REMOVE <lig> BOUNDARYCHAR <char> -> <char>= + +\verb=% comments, like in TeX= + +where {\tt <char>} means (like in a {\tt[V]PL} file, either +\verb=C= followed by a character, or \verb=D= followed by a +decimal number, or \verb=O= followed by an octal number, or +\verb=H= followed by a hexadecimal number. {\tt<lig>} means +one of the following: \verb=LIG=, \verb=/LIG=, \verb=LIG/=, +\verb=/LIG/=, \verb=/LIG>=, \verb=LIG/>=, \verb=/LIG/>=, +\verb=/LIG/>>=. + +Everytime you kern some letter, all previous kerning pairs +and ligatures are erased. By the {\tt UNKERN} command +you can erase these, without inserting a new character. +Commands are executed sequentially, and there is no +consistence test; so you can ask something and then +the opposite: nobody will complain. + +\section{An Example: Esperanto} + +Esperanto needs the following characters which are not +provided in the DC font: \^c, \^s, \^\j, \^g, \^h, \u u +(and the corresponding uppercase letters). Dirk Everdeen +which is an Esperanto guru (and has prepared a $\beta$ +version of Esperanto hyphenation patterns) asked me to use +the following input mechanism: these letters should be +accessed by ligatures {\tt cx}, {\tt sx}, {\tt jx}, +{\tt gx}, {\tt hx}, {\tt ux}, because the letter `x' is +not used in Esperanto. + +Since the ``phantom'' letter `x' comes {\em after} the +real letter, there is no problem with kerning (like in the +case of the input ligature {\tt ts} of the {\tt wncyr} fonts). +So this method could eventually be adopted as a standard +transliteration of Esperanto. But this is another +issue\footnote{To be solved by the Esperanto subgroup of +the Technical Working Group on Multiple Language +Coordination.}. + +Our problem now is to create a virtual font with these +letters, the right kerning pairs and the right ligatures. +I have chosen positions which would harm the least amount +of languages: only Turkish and Slovakian are excluded +when using this virtual font. + +How to call it? well, of course {\tt eocr10} since {\tt eo} +is the two-letter code for Esperanto. + +\subsection{First step: character description} + +How do we describe the accented characters? Let's use +Eberhard Mattes' {\tt QDTeXVPL}. For this we need a +configuration file, which will specify the positions +of new characters, and their descriptions in the form of +\TeX\ macros. Here is this file (let's call it +{\tt esperanto-wannabe.tex}): + +\begin{verbatim} +\font\f=dcr10 +\input qdtexvpl +\texvpl{^^ad}{\f\^s} +\texvpl{^^8d}{\f\^S} +\texvpl{^^a0}{\f\^c} +\texvpl{^^80}{\f\^C} +\texvpl{^^a8}{\f\^h} +\texvpl{^^88}{\f\^H} +\texvpl{^^a9}{\f\^\j} +\texvpl{^^89}{\f\^J} +\texvpl{^^a7}{\f\^g} +\texvpl{^^87}{\f\^G} +\texvpl{^^b8}{\f\u u} +\texvpl{^^98}{\f\u U} +\bye +\end{verbatim} + +The good thing is that we can quickly describe the characters +using \TeX\ macros, like \verb=\^=, \verb=\u=, \verb=\j=. +The bad thing is that this is all we can do. Fine tuning must +be done by hand. + +You run this file through \TeX\ and get file +{\tt espernato-wannabe.dvi}. Then you run {\tt QDTeXVPL} with +the followint command line: + +\begin{verbatim} +QDTeXVPL -d10.0 esperanto-wannabe.dvi esperanto-wannabe.vpl +\end{verbatim} + +Here is an extract of what we get: + +\begin{verbatim} +(MAPFONT D 16 + (FONTNAME dcr10) + (FONTCHECKSUM O 30523766474) + (FONTDSIZE R 10.000000)) +(CHARACTER O 255 + (CHARWD R 0.394347) + (CHARHT R 0.694275) + (CHARDP R 0.000000) + (MAP + (MOVERIGHT R -0.052765) + (SELECTFONT D 16) + (SETCHAR O 2) + (MOVERIGHT R -0.447113) + (SETCHAR C s))) +(CHARACTER O 215 + (CHARWD R 0.555420) + (CHARHT R 0.939255) + (CHARDP R 0.000000) + (MAP + (PUSH) + (MOVERIGHT R 0.027771) + (MOVEDOWN R -0.244980) + (SELECTFONT D 16) + (SETCHAR O 2) + (POP) + (SETCHAR C S))) +... +\end{verbatim} + +Now we have to replace these characters inside {\tt dcr10.pl} +and name the new file {\tt eocr10.vpl} (hopefully someday +somebody will find the time to write some utility to do this +automatically). + +\subsection{Second step: adjusting kerning pairs and ligatures} + +As you saw, we have modified character descriptions, but neither +kerning pairs, nor ligatures. This will be done by {\tt AdjKerns}. +Here is the necessary configuration file {\tt eo.kcf}: + +\begin{verbatim} +% Kerning and ligature configuration for +% Esperanto virtual fonts, based on DC +% Semi-official (not yet aproved by TWGMLC) +KERN H AD LIKE C s +KERN H 8D LIKE C S +KERN H A0 LIKE C c +KERN H 80 LIKE C C +KERN H A8 LIKE C h +KERN H 88 LIKE C H +KERN H A9 LIKE C j +KERN H 89 LIKE C J +KERN H A7 LIKE C g +KERN H 87 LIKE C G +KERN H B8 LIKE C u +KERN H 98 LIKE C U +ADD LIG C s C x -> H AD +ADD LIG C S C x -> H 8D +ADD LIG C S C X -> H 8D +ADD LIG C c C x -> H A0 +ADD LIG C C C x -> H 80 +ADD LIG C C C X -> H 80 +ADD LIG C h C x -> H A8 +ADD LIG C H C x -> H 88 +ADD LIG C H C X -> H 88 +ADD LIG C j C x -> H A9 +ADD LIG C J C x -> H 89 +ADD LIG C J C X -> H 89 +ADD LIG C g C x -> H A7 +ADD LIG C G C x -> H 87 +ADD LIG C G C X -> H 87 +ADD LIG C u C x -> H B8 +ADD LIG C U C x -> H 98 +ADD LIG C U C X -> H 98 +\end{verbatim} + +Note that we have included ligatures both for `Cx' and `CX' etc.: +the former will be used in text, the latter in titles. +Now we run {\tt AdjKerns}, with the following command line: + +\begin{verbatim} +AdjKerns -c eo.kcf eocr10.vpl +\end{verbatim} + +After some lines: + +\begin{verbatim} +************************************************************** + + This is program AdjKerns (= Adjust Kerning Pairs) + + Version beta-1 + written for you by a lousy C programmer + (Yannis Haralambous, 1993) + + It shall help you make efficient virtual fonts + This software belongs to the public domain + +************************************************************** +Loading input file preamble... +Reading kern and ligature data... +Reading lines from configuration file and executing them... +.............................. +Finished reading the configuration file +Writing down new lig/kern data... +Writing input file remaining data... +\end{verbatim} + +we get the expected result (our file {\tt eocr10.vpl} is +overwritten. + +\subsection{Final step: using the font} + +Once we have the {\tt VPL} file, we are done.
