Creeps (binding gutter / margin correction in imposition)
by Henning Hraban Ramm 10 Nov '16

10 Nov '16

Hi together, this is not really a practical request, but an interesting (I think) idea... ConTeXt can do simple imposition (arranging pages on sheets, see \setuparranging), but in professional imposition you need to compensate for the paper thickness in folds to keep pages readable - you can move the outer pages of a fold out of the gutter (spine), or move the inner pages to the spine. (This is called creep in English, Bundversatz in German.) That means, your outer margin will have different width, depending on the position of the page in its fold. See e.g. https://helpx.adobe.com/indesign/using/printing-booklets.html A guy on the LilyPond mailing list had the interesting idea to adapt the line width to this creep, to keep an even outer margin - it would mean that TeX needs to know about imposition while breaking lines. What do you think? Greetlings, Hraban --- http://www.fiee.net http://wiki.contextgarden.net GPG Key ID 1C9B22FD

Typing in natural width box
by Henri Menke 09 Nov '16

09 Nov '16

Dear list, To answer this question on TeX.SX https://tex.stackexchange.com/questions/338135/ I was trying to put a typing environment into a natural width box. It first seemed that framedtext is doing what I was after but it turned out that only the frame is adjusted to natural width, the underlying box is still full width. Therefore I tried framed but there I obtain spurious vertical space out of nowhere. How can I place typing into a natural sized box? Cheers, Henri --- \starttext \ruledhbox{% \startframedtext[width=fit,offset=0pt] \starttyping print("Hello World!") \stoptyping \stopframedtext } \ruledhbox{% \startframed[width=fit,align=right,offset=0pt] \starttyping print("Hello World!") \stoptyping \stopframed } \stoptext

indenting and whitespace in framedtext
by Meer, Hans van der 09 Nov '16

09 Nov '16

Quoting from the command reference: \startframedtext inherits \setupframedtext and \setupframedtext ... indenting = inherits \setupindenting I interprete this as \setupindenting is carried to the inside of the framedtext but this thus not happen. Instead one explicitely sets it on the call of \startframedtext. Why doesn't \startframedtext inherit the value from the document? This is a problem because I need this setup for framedtexts called in an inner module. A second, even more serious problem for me is that the framedtext is ignoring the \setupwhitespace. For both problems see the example below. Hans van der Meer \setupindenting[yes,first,medium] \setupwhitespace[big] \starttext \ConTeXt-version = \contextversion Text for testing indenting of praragraphs. A lot of nonsense just to fill the paragraph so that more than one line is typeset. A lot of nonsense just to fill the paragraph so that more than one line is typeset.

Dear Otared, Hi, I run the given code and got an error message as following. tex error > tex error on line 1 in file virtual://block.answer.2: ! Undefined control sequence l.1 \myanswer [Q:test] <empty file> Would you please tell me how to avoid such an error? It seems to me that you don’t have an error. I am running minimal(beta) in OSX.

Dear Otared, It is not the problem of your code. Strangely, the code you just sent to me is stopped by the same reason during the compilation even though it does not contain the word “myanswer”. After removing *.tmc file, the error disappear. I still don’t know why such an error occurred. Anyway, I got a nice sample which is very useful. Thank you. Best regards, Dalyoung

Error while trying to generate font database
by Sergey 06 Nov '16

06 Nov '16

Hi all, I've updated today my version of context (rsync route, following information on contextgarden). After performing the update I wanted to generate the font database following instructions on http://wiki.contextgarden.net/Fonts_in_LuaTeX. The following error emerged: ...ext/tex/texmf-context/tex/context/base/mkiv/font-otr.lua:102: attempt to index local 'streamreader' (a nil value) I run FreeBSD 11-CURRENT. Any clues as to what might cause the error message? Regards, Sergey

Clickable question/answer numbers
by Mikael P. Sundqvist 06 Nov '16

06 Nov '16

Dear list, I have a pretty large text with a lot of questions and answers, and want the user(students) to be able to click in the pdf to go from a certain exercise to its answer, and back. I have a solution (see below) to go from answers to questions, but not the other way around. I simply have no idea on how to make the red text (in the head) in the example question clickable with the answer on the next page as target. As you can see, the answer has a tag A:Q:test (I want to set these automatically in that manner), and clicking the green text I get to the correct place. I just don't see how to make the "Question 1.1" clickable with that target. I hope I make myself clear. If it matters, in the solution one could assume that the optional tag of the \startquestion \stopquestion is given for all questions. Best regards, Mikael %% qa.tex \setupinteraction[state=start,color=,contrastcolor=,style=] \defineblock[answer] \hideblocks[answer] \def\myanswer[#1]{\inleft{\in[#1]\reference[A:#1]{\in[#1]}}} \defineenumeration[question][ text=Question, headcolor=darkred, width=fit, number=yes, prefix=yes, prefixsegments=section, ] \starttext \section{A section with questions} \startquestion[Q:test] Solve this question! \stopquestion We could, however, click \color[darkyellow]{\in{Answer}[A:Q:test]}. \beginanswer \myanswer[Q:test] What question? The answer is \quotation{do it yourself}! \endanswer \page[yes] \subject{Answers} \useblocks[answer] \stoptext

floats in xtable flush with frame
by Michael Eidenbenz 05 Nov '16

05 Nov '16

Hello, I want to place floats in an xtable but cannot get rid of the gap between the float and the frame. I sort of can eliminate the gap on the top with \setupfloat [offset=-2.5pt] but this doesnt seem to be the right way. Is there a parameter to control this? Thanks Michael \showframe \starttext \startxtable \startxrow \startxcell \placefloat{}{\externalfigure[][width=\textwidth/2]} \stopxcell \startxcell \placefloat{}{\externalfigure[][width=\textwidth/2]} \stopxcell \stopxrow \stopxtable \page \setupfloat [offset=-2.5pt] \startxtable \startxrow \startxcell \placefloat{}{\externalfigure[][width=\textwidth/2]} \stopxcell \startxcell \placefloat{}{\externalfigure[][width=\textwidth/2]} \stopxcell \stopxrow \stopxtable \stoptext

I have updated the Vim page at ConTeXt Garden: http://wiki.contextgarden.net/Vim It may be considered as the official documentation of the ConTeXt scripts in Vim, as the only other documentation is the source code :) Happy editing! Nicola
