\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 03 Aug '14

03 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

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

Lua to Context Table
by John Kitzmiller 01 Aug '14

01 Aug '14

Here is Lua code that prints the first nine fibonacci numbers: local function fib(n) f={1,1} for i=3,9 do f[i]=f[i-1]+f[i-2] end return(f[n]) end for n=1,9 do print(fib(n)) end Here is Context+Lua that prints 3 x 3 table of the first nine natural numbers: \starttext \setupTABLE[each][each][frame=off,align=left,width=4em,height=2em] \startluacode context.bTABLE() for j = 0, 2 do context.bTR() for k = 1, 3 do context.bTD() context(3*j+k) context.eTD() end context.eTR() end context.eTABLE() \stopluacode \stoptext How can these be combined to print a 3 x 3 table of the first nine fibonacci numbers? I have tried a couple of ways to iterate over the lua table f in the most indented line of context, looked at what pertinent threads I could find, the Wiki entries, CLD, and tried Aditya's method from Stack Exchange; I am missing something.

Hyphenatedurl: custom line-break symbol, disable stretching
by Joshua Krämer 01 Aug '14

01 Aug '14

Dear list, I typeset URLs with \hyphenatedurl, and have two questions. (1) Is there a feature available to insert a custom symbol when a line-break occurs, e.g. \hookleftarrow? (2) How can I disable the stretching between characters? I've tried the following without success: \setupurl [space=no] \setupurl [urlspace=no] \unprotect \def\lang_url_space{} \protect Thanks and kind regards, Joshua

s-edu-01.cld

Where to find s-edu-01.cld mentioned in Context Lua Documents? I use minimals, just updated, --modules="all" --engine="luatex". Also tried --modules="s-edu-01.cld" as well as Google.
