LuaTeX has troubles with contextual kern
by Georg Duffner 25 Apr '13

25 Apr '13

Hi, in EB Garamond I have some contextual lookups in the kern feature with which LuaTeX in context standalone (updated today in the morning) seems to have problems (the issue is not new, I’ve already reported it in january but perhaps that was a bit too confusing). The test document is: \definefontfeature[default][default][mode=base] \definefontsynonym[ebg][file:EBGaramond12-Regular.otf] \definefontfeature[ss20][ss20=yes] \definefontfeature[iota1][cv81=1] \definefontfeature[iota2][cv81=2] \definefontfeature[altcirc][cv80=1] \define\test{Tì αᾟα\par} \starttext \definedfont[ebg*default at 12pt]\test \addfeature{ss20}\test \addfeature{iota1}\test \addfeature{iota2}\test \addfeature{altcirc}\test \stoptext The font is at http://www.georgduffner.at/ebgaramond/fonts/EBGaramond12-Regular.otf The corresponding lookups in the kern.fea roughly contain pos T' 145 i.dotless gravecomb; which increases the right sidebearing of T by 145 before i.dotless followed by gravecomb and pos Eta' <218 0 218 0> uni0345.cap @grk_tlAcc2; pos Eta' <218 0 418 0> uni0345.cap1 @grk_tlAcc2; pos Eta' <218 0 558 0> uni0345.cap2 @grk_tlAcc2; where @grk_tlAcc2 contains the accents attached at the top left of the glyph and which means that Eta is positioned at 218 inside its bounding box and the bounding box is expanded by the third value between <>, on the condition that it’s followed by uni0345.cap* and the said accents. ss20 does a full decomposition of all composed glyphs so I can replace any component by an alternate glyph. Their order corresponds to canonical decomposition. Attached you find the pdf output and a pdf from a parallel xelatex test which shows the desired result: \documentclass[12pt]{minimal} \usepackage{fontspec} \setmainfont{EB Garamond} \newcommand{\test}{Tì αᾟα\par} \begin{document} \test \addfontfeature{RawFeature=+ss20}\test \addfontfeature{CharacterVariant=81:1}\test \addfontfeature{CharacterVariant=81:2}\test \addfontfeature{CharacterVariant=80}\test \end{document} Best regards, Georg

disabling a header on the first page
by Lance Larsen 25 Apr '13

25 Apr '13

I am building a context document with a title page. I want to disable the header on the title page. This comes before the first \chapter tag. The documentation indicated that you can disable the header on a page with the \page command. I tried several different things as the first command after \starttext, but none of these disabled the header: \page[header=none] \page[header] \page[header=high] Can anybody tell me how I disable the header on the first page? I would really appreciate the help. -Lance Larsen

Accessing string contents of a macro in Lua.
by Sietse Brouwer 24 Apr '13

24 Apr '13

Hi all, Below are three methods of defining a dimension / dimension string in ConTeXt --- the first two boil down to storing a string in a macro, the last is a proper TeX dimen. I want to access these dimensions from Lua. I can access the dimen via tex.dimen.ColumnC, but how can I access the macro contents? If there is no solution, I can always explicitly pass the value to Lua with \ctxlua{var = '\measure{ColumnA}'} , but I want to know if there is a Lua-only method to get these values. %% MWE \definemeasure[ColumnA][10mm] \def\ColumnB{20mm} \newdimen\ColumnC \ColumnC=30mm \startluacode -- print values to stdout logs.report('====') logs.report('ColumnA', context.measure('ColumnA')) logs.report('ColumnB', context.ColumnB) logs.report('ColumnC', tex.dimen.ColumnC) -- prints in scaled points print('====') \stopluacode Cheers, Sietse

[luatex-fonts] error with Amiri due to inclusion of font-otp.lua
by Philipp Gesang 24 Apr '13

24 Apr '13

Hi, including font-otp triggers an error with the Amiri font: ! LuaTeX error ./luaotfload-merged.lua:10471: invalid value (nil) at index 1 in table for 'concat'. Which corresponds to line 192 of font-otp.lua. Test code: \font\test={file:amiri-regular.ttf} \test ضرب \bye Or with Context: \mainlanguage[arabic] \definefontsynonym[amiri][file:amiri-regular.ttf] \starttext \definedfont[amiri*arabic at 42pt] \setupalign[r2l] ضرب 0123456789 \stoptext I have tested the Amiri files from TeX Live 2012 and 2013. Can somebody reproduce this, possibly with other fonts? Scheherazade works fine. Thanks for any advice Philipp

I don't understand the above statement. What number of lines does 60 exceed? Is there a hard-coded limit? (We didn't seem to have a problem with this code before we migrated from XeTeX / mkii to LuaTeX / mkiv, but I couldn't guarantee what else is different.) Is there a workaround for us now? I could leave out the \setupcolumnsetlines commands for the moment, and hope we don't overflow the page. Actually I'm not sure what will happen if we leave the number of lines at the default (which is apparently zero?).

Ok, I now put the \ctxlua into an other chapter: http://wiki.contextgarden.net/Calculating_with_dimension_units Can you say something to the missing points there? "Wich meethod?", "\the" and "Expanding If you don't know how to edit the context-wiki, please write your information here in the mailinglist - then I will put it into the wiki. Regards Jannis

A simpler way to make a bibliography
by john Culleton 23 Apr '13

23 Apr '13

After struggling with all the programming prescribed by Context to set up a bibliography, and examining a few dozen *.bib, *.bst and a *bbl file, I decided to do things the simple way. My concept is, that instead of creating a *bib file I could with the same amount of effort create a plain text file to be imported directly into my Context file. I studied the bibliography of "The Chicago Manual of Style" to determine the order, punctuation and format. My file is called "book.foo." Now if I choose to use some of these entries in another book a simple cut and paste between two editor sessions will do. For ease in editing I put each item in each entry on a separate line. TeX/Context will take care of puttng them together in a paragraph. Of course this lacks the generality of the bibtex approach. But I don't need all that flexibilty. None of the current biblio styles specified for Context incorporate the ISBN field. So I just put it at the end of each entry preceded by a \crlf. Without further ado here is the book.foo file: ------------------------------------------ \chapter{References} %authors. title. city: publisher, year\crlf %isbn Bah, Tavmjong. {\it Inkscape: Guide to a Vector Drawing Program}. Upper Saddle River, New Jersey: Prentice-Hall, 2011 \crlf ISBN 978-0-13-276414-8 Culleton, John R. Jr. {\it Create Book Covers with Scribus} (pdf e-book). Eldersburg, Maryland: Wexford Press, 2012 \crlf ISBN 978-1-60019-002-5 Drew, Ned and Paul Sternberger. {\it By its Cover: Modern American Book Design}. New York: Princeton Architectural Press, 2005\crlf ISBN 978-1-56898-497-1 Kirsanov, Dimitry. {\it The Book of Inkscape\trademark : The Definitive Guide to the Free Graphics Editor}. San Francisco: No Starch Press, 2009\crlf ISBN 978-159327-181-7 Powers, Alan. {\it Front Cover: Great Book Jacket and Cover Design}. London: Mitchell Beazley, 2006\crlf ISBN 978-1-84533-242-6 ------------------------------------------- If by chance an entry ends up split between two pages a simple \page[yes] command can be inserted. I considered instead putting a \goodbreak between entries but figured it wasn't worth the bother. Since I call this fragment a \chapter it is listed in the TOC. I had to put \whitespace[medium] right after the \startbackmatter command just as I did after \startbodymatter. for my purposes for this task simple is better and much faster. -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html PDF e-book: "Create Book Covers with Scribus" available at http://www.booklocker.com/books/4055.html

localfootnotes and bodyfontsize in a placetable
by Alan BRASLAU 23 Apr '13

23 Apr '13

The following attached "minimal" example using local footnotes and a small body font size exhibits two problems: 1. The \placelocalfootnotes are incoherently in the "normal" size, as I would expect them to be proportionally reduced. 2. The width of the first column gets incorrectly set (there is a break between "a" and "cell"). Probably there is a better way of achieving this correctly.

Set background color for a single page
by Tim Li 23 Apr '13

23 Apr '13

Sometimes, I only want a single page, say, the titlepage or page 32, with colored background rather that the whole document. Here are some codes: \starttext% titlepage (yellow) \startmakeup[standard] \midaligned{How to make document} \stopmakeup % page1 (gray) Many \CONTEXT\ users $\ldots$ \page % page2 (darkyellow) Many \TEX\ users $\ldots$ \stoptext Of course, it is awful that if I set the titlepage yellow, page1 gray and page2 darkyellow. How can I achieve this? regrads, Tim
