Basic \def error?
by Verhaag, G.C.H.M. 25 Apr '13

25 Apr '13

Hi ConTeXt User's, Again I'm struggling with MKIV! I get the following error message: ! Argument of \HeadTitle has an extra } My environment file contains the following definition: \def\HeadTitle#1#2% {\hbox to \hsize \bgroup \hfill \lbox to 2cm{\hsize 7cm #2}% \egroup} \setuphead [chapter] [command=\HeadTitle] In the text I use: \chapter[voorwrd]{Voorwoord} I updated to the following version: ConTeXt ver: 2013.04.20 01:15 MKIV current fmt: 2013.4.22 int: english/english, but must admit that I haven't used ConTeXt for quite a while! Probably I've missed something but couldn't find any hint from the mail archive to solve this problem, sorry! Regards, Verhaag,G.C.H.M.

Project structure and path evaluation
by contact＠thomas-corbiere.name 25 Apr '13

25 Apr '13

Hello, I am experimenting with the project structure feature of ConTeXt and so far it seems that paths used with \project, \product and \component are relative to the current working directory of the context program. What I am doing right now, I use paths relative to my project file "project.tex". project.tex: \startproject proj \product product1/product.tex \product product2/product.tex \stopproject product1/product.tex: \startproduct prod1 \component product1/components/component1.tex % I would like to use "components/component1.tex" % that is a path relative to the current file \stopproduct This is really annoying as it makes it difficult to organize files into directories. I would like the path to be relative to the file containing the command. I tried \usepath[{.}] without success. So, is this possible in ConTeXt? Also, at the end of the PDF on project structure there is an example with \startdocument ... \stopdocument. But I don't understand where I should use these commands. From the source, it looks like \starttex ... \stoptext with the ability to register a before and after command. I am under the impression that I have to choose between using : - the project structure (project, product and component) - the \startdocument and \stopdocument commands - the \starttex and \stoptext commands But that I should not mix them together. Is this right? Regards, Thomas Corbière

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
