Hello, I'm trying to get the subject heading in the margin. I found this code on the wiki, but it is not compiling with the latest version of ConTeXt. \setuppapersize[A5] \setuphead [subject] [alternative=text,distance=0pt,command=\MyHead,style=\sc] \def\MyHead#1#2{\inmargin{#1 #2}} \starttext \subject{First Subject} \input weisman \subject{Second Subject} \input ward \stoptext from http://wiki.contextgarden.net/Titles#Titles_in_margin The error being thrown is ! Argument of \MyHead has an extra } Please help! Best, Mica

Custom breakpoints for \hyphenatedurl
by Joshua Krämer 07 Aug '14

07 Aug '14

Dear list, I could successfully configure ConTeXt to introduce linebreaks /after/ some characters in URLs with \sethyphenatedurlafter {...} I would also like to disable linebreaks /before/ some of the predefined characters. For example, no linebreak should occur before : Is this possible? \sethyphenatedurlbefore {} (with empty braces) does not work. Unfortunately, usage of \sethyphenatedurlafter also introduced the following problem: the \hyphenatedurlseparator symbol now appears after the linebreak, i.e. at the beginning of the new line. Can I do something about it? Thanks and kind regards, Joshua

Accessing the URL of \useURL (for putting URLs into footnotes)
by Matthias Weber 07 Aug '14

07 Aug '14

Dear All, for the printable version of a document I’d like to put the actual URLs into footnotes. In other words, I’d like to replace \setupinteraction [state=start] \starttext \useURL [garden] [http://wiki.contextgarden.net/Main_Page] [] [ConTeXtgarden] \starttext Look at the \from[garden]! \stoptext with \setupinteraction [state=start] \starttext \useURL [garden] [http://wiki.contextgarden.net/Main_Page] [] [ConTeXtgarden\footnote{\hyphenatedurl{http://wiki.contextgarden.net/Main_Pa…] \starttext Look at the \from[garden]! \stoptext To save me from retyping all the URLs, there must be some way to access the URL of garden instead of the display text so that I could do something like \def\myfrom[#1]{ \startmode[screen] \from[1] \stopmode \startmode[print] \from[1] \footnote{\hyphenatedurl{get the URL text from \useURL instead of the display text}} \stopmode } Thanks, Matthias

\definefallbackfamily and small h
by Mikael P. Sundqvist 05 Aug '14

05 Aug '14

Dear list, I have a problem with the small letter h when I do a \definefallbackfamily. Example: \definefontfamily [myface] [rm] [TeX Gyre Pagella] \definefallbackfamily[myface][math][TeX Gyre Termes][preset=math:lowercaseitalic] \definefontfamily[myface][math][TeX Gyre Pagella Math] \setuppagenumbering[state=stop] \setupbodyfont[myface] \starttext $h$ \stoptext I get the h set in Pagella. With any other letter I get Termes... In my real example I do not want to replace with Termes but with a font (FrutigerLTstd) that does not have a math version. It seems (when I look with gnome character map), that the letter h is missing (or, probably, to be found elsewhere) from all fonts. Is there any chance I can fix this substitution manually for the letter h? /Mikael

Accessibility
by D.K. 04 Aug '14

04 Aug '14

Dear all, I am trying to produce an accessible document using ConText. Tagging with MkIV works, but in order to ensure that the resulting PDF meets accessibility requirements, I'd like to pass Acrobat Pro's accessibility check. I stumbled across the following questions so far: 1.) Is it possible to produce a tagged pdf document that either tags the page numbers as part of the content, or as a non-textual element? Acrobat Pro's accessibility checker complains that the page number is not tagged at all in produced PDFs. 2.) Is it possible to provide an alternative text for an included image? I cannot find an option for \externalfigure that would provide an alt-text for an image (and hence, Acrobat Pro complains) 3.) Is it possible to ensure that the document language in the resulting PDF is set? I.e. \mainlanguage[en] will not result in a PDF where the language is set, and thus Acrobat Pro complains. kind regards

Bug with the integration with tikz
by Günter Kolousek 04 Aug '14

04 Aug '14

I think there is a bug in the (latest) beta (2014.07.30 10:31 MKIV beta fmt: 2014.8.2 int: english/english) that was *not* there earlier this year! Please, could somebody help and maybe provide a tip for a workaround? It concerns the integration with tikz where I get now the following error message: util-lib.lua:246: module 'pgf.gd.control' not found: no field package.preload['pgf.gd.control'] no file '/usr/local/share/lua/5.2/pgf/gd/control.lua' no file '/usr/local/share/lua/5.2/pgf/gd/control/init.lua' no file '/usr/local/lib/lua/5.2/pgf/gd/control.lua' no file '/usr/local/lib/lua/5.2/pgf/gd/control/init.lua' no file './pgf/gd/control.lua' no file '/usr/local/lib/lua/5.2/pgf/gd/control.so' no file '/usr/local/lib/lua/5.2/loadall.so' no file './pgf/gd/control.so' no file '/usr/local/lib/lua/5.2/pgf.so' no file '/usr/local/lib/lua/5.2/loadall.so' no file './pgf.so' stack traceback: [C]: in function 'savedrequire' .../context/tex/texmf-context/tex/context/base/util-lib.lua:246: in function 'require' ...neric/pgf/graphdrawing/lua/pgf/gd/control/Sublayouts.lua:41: in main chunk [C]: in function 'savedrequire' .../context/tex/texmf-context/tex/context/base/util-lib.lua:246: in function 'require' ...graphdrawing/lua/pgf/gd/interface/InterfaceToDisplay.lua:45: in main chunk [C]: in function 'savedrequire' .../context/tex/texmf-context/tex/context/base/util-lib.lua:246: in function 'require' [\directlua]:1: in main chunk 1101 } 1102 } 1103 1104 1105 % 1106 % Ok, fire up the system by creating the binding! 1107 % 1108 \directlua{ 1109 require 'pgf.gd.interface.InterfaceToDisplay' 1110 pgf.gd.interface.InterfaceToDisplay.bind(require 'pgf.gd.bindings.BindingToPGF') 1111 >> } A minimal example is: \usemodule[tikz] \usetikzlibrary[graphs] \usetikzlibrary[graphdrawing] \starttext \starttikzpicture \graph { a -> {b, c} -> d }; \stoptikzpicture \stoptext Günter

Leave out reference to page if on the same page?
by Gerben Wierda 02 Aug '14

02 Aug '14

Suppose I have this fragment: is shown in \in{figure}[foo] on \at{page}[foo]. \placefigure [] [foo] I would like to leave the fragment “on \at{page}[foo]” out of the text if the figure ends up on the same page as the \at. Is that doable or is this a matter of manual tweaking at the end? G

Blackboard signs for set of rationals (Q) and reals (R)?
by Gerben Wierda 02 Aug '14

Just a simple question I could not find the answer for in the docs. What do I need to get the blackboard style (double lines) characters for R (the set of real numbers) and Q (the set of rational numbers) in a ConTeXt document? G

Thanks to you both! I missed the global/local conflict, and then learned a way to avoid double computation; thanks again! John
