manipulate ttf-fonts loaded with luatex
by Ulrike Fischer 02 Nov '10

02 Nov '10

Hello, I'm currently a bit playing around with the idea to add some support in the (LaTeX) package "chessfss" (which handle chess fonts) for fonts loaded with the luaotfload package. As luaotfload use the context code to load the font I'm hoping that someone here can help me with some of my problems. Chess fonts are highly unstandard. The different authors of the fonts did put the chars quite randomly in the character table and also used various glyphs name. So in the psfonts.map almost every font has its own encoding vector: chess-pirat-lsf ChessFigurinePirat " ChessPiratFigEncoding ReEncodeFont " <chess-pirat-fig.enc <chess-pirat-fig-raw.pfb So to be able to use ttf/otf-fonts directly I must "reorder" the glyphs in the fonts (without changing the original fonts). As a first step I was able to substitute glyphs with a .fea-file: feature renc { substitute K by "glyph name of king"; } renc; But doesn't work all the time. E.g. the pirat font (http://www.enpassant.dk/chess/downl/pirat.zip) shows already some on the problems of the project: The king with the glyph name c140 is shown in fontforge on position 140 with a "å" above. The å is shown on position 229 with an "Å". luaotfload seems to think that there are two "aring" and so the temp-lua-file of the font contains in the unicodes table the enrty "c140={ 229, 140 }" and my substituation rule gets me an "å" instead of the King I want. I get the correct substituation if I manually change the entry "c140={ 229, 140 }" to "c140=140. So here the questions: 1. How can I make this change after the font has been defined? I tried to find table entries which do contain this setting and change them, but without luck. So either I didn't find the right table or I need to execute some "reload" funktion. 2. Is there another way to reorder the font than using .fea-files? E.g. by changing some font entries? 3. I can print the king by using its position with \char140. But how can I print the king in a document by using its glyph name (c140)? 4. Quite a lot chess fonts are incomplete. Is is possible to insert glyphs from other fonts? Btw: The font Alfonso (http://www.enpassant.dk/chess/downl/alfonso.zip) gives an error message. Probably the font is faulty somehow (I wouldn't be surprised) but perhaps it also indicates a hidden bug, so I'm mentioning it: \documentclass{article} \usepackage{luaotfload} \begin{document} \font\test={name:Chess Alfonso-X} \test \fbox{K} \end{document} ! LuaTeX error J:/MiKTeX2.9/tex/luatex/luaotfload/otfl-font-otn.lua:2398: table index is nil. <to be read again> \test -- Ulrike Fischer

Feature request: list of abbreviations
by Otared Kavian 02 Nov '10

02 Nov '10

Dear Hans, Some time ago you said it would not be difficult to have the list of abbreviations listed in the opposite order, that is The full form the short form and you told me to remind you later about this feature request. That is what I am doing now… If one considers the minimal example: % ----- begin abbrev-test.tex \definesynonyms[abbreviation][abbreviations][\infull][\inshort] \starttext \abbreviation{LCTVS}{Locally Convex Topological Vector Space} \abbreviation{EEG} {Electroencephalogram} \abbreviation{ERP} {Event-Related Potentials} \abbreviation{TVS}{Topological Vector Space} Test inshort: \inshort{EEG}, \inshort{ERP}, \inshort{TVS}, Test infull: \infull{EEG}, \infull{ERP}, \infull{TVS}, \infull{LCTVS} \completelistofabbreviations \stoptext % ----- end abbrev-test.tex Is it possible to obtain, beside the list of abbreviations, another ordered list in which the full variant is in the first column while the short variant is in the second column? That is a new command, or an option in the \setupListOfAbbreviations, resulting in Electroencephalogram EEG Event-Related Potentials ERP Locally Convex Topological Vector Space LCTVS Topological Vector Space TVS Thanks in advance for any help or insight. Best regards: OK

Animations
by Wolfgang Schuster 02 Nov '10

02 Nov '10

Hi Hans, this is a feature request regarding fieldstack based animations. Since i want to use fieldstacks in one of my modules i’m looking for a simple to use interface to produce animations, for the moment i create a symbol for each frame and put them together with a fieldstack. For latex there is a package called animate [1] which provides a environment to produce animations with buttons for navigation (just a take a look at the examples in the manual, code is not relevant for us). I wrote now a short dummy module [1] to demonstrate how this could look in context, the first file [1] contains a few example, the environment is inspired by \startoverlay/\stopoverlay but it needs a alternative method to allow loops (look at the third example in this file). The second test file shows which navigation buttons i want for such a module, the are “first frame”, “previous frame”, “play” and “stop” animation, “next frame” and “last frame”. As a alternative one can produce a animation with a overlay button only with a symbol on the first frame to indicate a interactive element.

math chars
by Oliver Buerschaper 01 Nov '10

01 Nov '10

Hi, I'm trying to access a few glyphs: --- \usetypescript [cambria] \setupbodyfont [cambria] \starttext n-ary summation (base), U+02211: \char"02211 n-ary summation (next), U+F0419: \char"F0419 n-ary summation (next), U+F041A: \char"F041A cyrillic capital letter ka, U+0041A: \char"0041A set minus, U+02216: \char"02216 mathematical script capital a, U+1D49C: \char"1D49C minus sign with falling dots, U+02A2B: \char"02A2B \stoptext --- but the summation substitutes as well as the script letter fail :-( Their numbers I took from: --- \usemodule [fnt-25] \usetypescript [cambria] \setupbodyfont [cambria] \starttext \showmathfontcharacters \stoptext --- I also tried --- \starttext \showfont[cambria.ttc][all] \stoptext --- but apparently there are no summation glyphs in the table at all. What am I missing? Best, Oliver
