which command would give the same effect as \pause in beamer ?

Hello, I have been switching to conTEXt to prepare some of my teaching stuff. I have read the context ref manual, the wiki and browsed the web, but couldn't find anything related to so-called overlays in beamer (I justed greped mail archives for 2015–2017). What would be the conTEXt way to have a list or whatever else displayed in a slide in such a way that point 2 is hidden until you press space, and so on. In beamer, you would make it this way \begin{frame} \begin{itemize} \item 1 \pause \item 2 \pause \item 3 \end{frame} Or even better, \begin{frame} \begin{itemize}[<+->] \item 1 \item 2 \item 3 \end{frame} I read about \starthiding and \stophiding in the manual, but as far as I understand, this is not exactly what I am looking for. I don't think postponing would help either. Any suggestion will be welcome. I am using texlive 2015 version (nothing newer is available yet in OpenBSD). Have a nice day, Damien Thiriet

Lua code and percent sign

27 Feb '17

The following code, from the wiki, results in a compilation error: \starttext > \ctxlua{context(string.format("\%.2f", math.pi))} > \stoptext The error is: [\directlua]:1: invalid escape sequence near '\%' > 1 \starttext > 2 > 3 >> \ctxlua{context(string.format("\%.2f", math.pi))} > 4 > 5 \stoptext I ended using \letterpercent command but it is not very convenient.

Question on "back" key in \blank
by josephcanedo＠gmail.com 26 Feb '17

26 Feb '17

Dear list, Sorry if question is trivial but I’d like to use « back » key in \blank to discard a \blank just before. The following MWE illustrates : \starttext Title. \blank[none] \blank[back, -line] %% I’d expect this one to discard the \blank[none] (as if it was not present) \startalignment[broad, flushright, hanging]Right.\stopalignment \stoptext I’d expect that Title and Right words to be on the same line, but they are not. Did I misunderstood the meaning of ‘back’ key ? Thanks a lot for help and time, Best regards Joseph Canedo

issue with linenotes and columns
by Pablo Rodriguez 26 Feb '17

26 Feb '17

Dear list, I have the following sample: http://www.ousia.tk/hippocratic-oath.tex After the fix from last beta, I’m afraid I’m still experiencing wrong column breaks, as displayed in http://www.ousia.tk/hippocratic-oath.pdf. Page 1: last line from first column should move to second column. Page 2: totally unbalanced columns. Page 3: first line from second column should be moved to first column. Page 4: I wonder why there is so much spaceinbetween notes (more than a line, as far as I can tell) and no spacebefore. For all pages: if setups are exactly the same, why does the first group of linenotes (dict) have a bigger interlinespace than the second group? Another question is how I should get columns for \placelist[dict]? Is the columnn breaking issue a bug or am I missing something? Many thanks for your help, Pablo -- http://www.ousia.tk

btx problem with FILM
by Rik Kabel 26 Feb '17

26 Feb '17

One more btx issue. The output from the following \startbuffer[TestBib] @FILM{Film1, producer = {Lasta, A.}, director = {Lastb, B.}, title = {Title1}, year = {2017}, publisher = {Publisher}, address = {Address}, } @FILM{Film2, producer = {Lasta, A.}, director = {Lastc, C.}, title = {Title2}, year = {2017}, publisher = {Publisher}, address = {Address}, } \stopbuffer \loadbtxdefinitionfile[apa] \usebtxdefinitions [apa] \usebtxdataset [TestBib.buffer] \definebtxrendering [Pubs][apa] \enabletrackers[publications.authorhash] \starttext \placelistofpublications[Pubs][method=dataset] \stoptext is incorrect. The director of the second film is lost, and the use of a bib dash makes it look like Film1 director is associated with Film2. There should be two separate entries: Lasta, A. (Producer), & Lastb, B. (Director) (2017). /Title1./ [Motion picture]. Address: Publisher. Lasta, A. (Producer), & Lastc, C. (Director) (2017). /Title2./ [Motion picture]. Address: Publisher. -- Rik

issue with OT feature lfbd
by Pablo Rodriguez 25 Feb '17

25 Feb '17

Dear list, I have the following sample: \showframe \definefontfeature[leftbounds][lfbd=yes] \definefontfamily[mainface][rm][Linux Libertine O] \setupbodyfont[mainface, 150pt] \starttext \startTEXpage[offset=1ex] Wer War? \addff{leftbounds} Wer War? Wer\subff{leftbounds} War? \stopTEXpage \stoptext I’m afraid that the OT feature lfbd is applied in all the line. Otherwise, the second and the third lines would have the same spacing between words. Could anyone confirm this or am I missing something? Many thanks for your help, Pablo -- http://www.ousia.tk

issue with linenotes and luatex-1.0.3
by Pablo Rodriguez 25 Feb '17

25 Feb '17

Dear list, I have a text with two kinds of linenotes (http://www.ousia.tk/hefes.tex) If I compile with latest beta (2017.02.23 18:37), I get wrong separation from body in many pages (http://www.ousia.tk/hefes.pdf) Only page 5 might be be right in this point. But if I use beta from 2017.01.27 14:39 (which comes with luatex-1.0.0 [at least in Linux 32bit]), linenote separation from body is much better (http://www.ousia.tk/hefes-nospacebefore.pdf) The spacebefore option from \setupnotes was intended to improve the situation. No matter whether \setupnotes is used or not, luatex-1.0.3 gets wrong results. Could anyone confirm the bug or tell me what I’m doing wrong? Many thanks for your help, Pablo -- http://www.ousia.tk

Bibliography issue, @ELECTRONIC editor
by Rik Kabel 25 Feb '17

25 Feb '17

ConTeXters, The following example demonstrates an issue with the ELECTRONIC bib type: \startbuffer[TestBib] @ELECTRONIC{Edited, editor = {An Editor}, title = {A title}, url = {http://www.example.com}, year = {2017}, } @ELECTRONIC{Authored, author = {An Author}, title = {Another title}, url = {http://www.example.com}, year = {2017}, } \stopbuffer \loadbtxdefinitionfile[apa] \usebtxdefinitions [apa] \usebtxdataset [TestBib.buffer] \definebtxrendering [Pubs][apa] \enabletrackers[publications.authorhash] \starttext \nocite[*] \placelistofpublications[Pubs] \stoptext Although either editor or author should be accepted, only author is processed. There is a warning message generated by the publications subsystem: unable to create short for 'Edited', needs one of [author,editor] but clearly there is an editor. A reasonable workaround is to use author instead of editor, but it would be nice to have a fix. -- Rik

new lua/stack error
by Alan Bowen 24 Feb '17

24 Feb '17

The latest beta — ConTeXt ver: 2017.02.19 with LuaTeX, Version 1.0.3 — chokes on entries such as \cite[author1, author2, and author3 2017] and reports an error: e.g., lua error > lua error on line 81 in file c_Brill09-02_Evans.tex: C stack overflow stack traceback: [C]: in function 'type' ...eXt/tex/texmf-context/tex/context/base/mkiv/lpdf-ini.lua:373: in function <...eXt/tex/texmf-context/tex/context/base/mkiv/lpdf-ini.lua:367> [C]: in function 'tostring' ...eXt/tex/texmf-context/tex/context/base/mkiv/lpdf-ini.lua:342: in function <...eXt/tex/texmf-context/tex/context/base/mkiv/lpdf-ini.lua:317> If I try something like \cite[A B and C] all is well. Adding the commas as in \cite[A, B, and C] gets the error. Sadly, I need the commas. Alan

floats on pages without headers
by Alan Bowen 24 Feb '17

24 Feb '17

I have some large floats that look best on empty pages, i.e., pages that do not have headers? The wiki suggests that location=page will put the float on an empty page but this does not seem to be the case: \starttext \dorecurse{3}{\input knuth} \startplacefigure[title=Cow, location={page}] {\externalfigure[cow.pdf][width=.7\textwidth]} \stopplacefigure \dorecurse{3}{\input knuth} \stoptext I am using the latest beta.
