Support for Optional Content Groups
by Chris Chapman 22 May '16

22 May '16

I am new to ConTeXt (coming from LaTeX), and am really impressed. Great work! I am working on a document that has layers that I want to be screen-only, similar in approach to this: http://tex.stackexchange.com/questions/167846/implementing-full-page-screen… I am assuming that Optional Content Groups would be the best way to do this. How would I set something up like this in ConTeXt/LuaTeX? I know I could make a screen-only version and a print version of the output pdf, but I want to have my cake and eat it too ;) Thanks in advance, Chris Chapman

new features
by Hans Hagen 22 May '16

22 May '16

Hi, (mostly for Thomas) In the next beta: When you include files in another file (using xmlinclude) we now register what gets included. There are two new commands: \xmlinclusion{#1} : the current inclusion \xmlinclusions{#1} : a list of inclusions the first one backtracks till it find a name and the second one will locate the root if needed. This option can be handy for tracing (i.e. seeing where input comes from). Another addition is that \definemode[something][keep] define an undefined mode; the keep makes sure that the already set value is kept (another option is 'yes'). Using defined modes (that is, set with: \enabledmode, \disablemode or \definemode) can be tested about twice as fast as undefined modes which can make a small difference when modes are tested lots of times.

bibliography tool
by Gour 22 May '16

22 May '16

I was browsing docs in the contextgarden but not sure what is available for handling bibliography in ConTeXt today? Afaict, RefTeX is for LaTeX only, I recall there was(is). (My dev environment is Debian Linux/Emacs/AUCTeX.) Sincerely, Gour -- Whatever action a great man performs, common men follow. And whatever standards he sets by exemplary acts, all the world pursues.

Overlays as background in textbackground

Hi, overlays are not displayed when used as a background for textbackground. Is this a bug or are overlays not supported? \defineoverlay [myoverlay] [\ssd Foo] \definetextbackground [mybackgroundColour] [background=color, backgroundcolor=gray] \definetextbackground [mybackgroundOverlay] [background=myoverlay] \starttext %% overlay works \framed [background=myoverlay, align=normal] {\input knuth\par} %% background=color works \startmybackgroundColour \input knuth \stopmybackgroundColour %% overlay is missing \startmybackgroundOverlay \input knuth \stopmybackgroundOverlay \stoptext Marco

halign broken
by Meer, H. van der 16 May '16

16 May '16

There seems something very much amiss with \halign in later ConTeXt versions. This typesets fine in PlainTeX and is an example taken from a textbook. \tabskip=1em\halign{% \hfil\it#\hfil&\hfil#\hfil&#&\hfil#\crA&B&C&D\cr} Also in contextversion 2012.05.30 (from a TeXlive distribution). But it fails at least in ConTeXt ver: 2013.03.20 10:34 MKIV and in ConTeXt ver: 2013.04.16 12:08 MKIV beta with the following error ! Only one # is allowed per tab. system > tex > error on line 5 in file fixedwidth.tex: Only one # is allowed per tab ... 1 \starttext 2 contextversion=\contextversion\par 3 \tabskip=1em 4 \halign{% 5 >> \hfil\it#\hfil&\hfil#\hfil&#&\hfil#\cr 6 A&B&C&D\cr} 7 \stoptext l.5 \hfil\it#\hfil&\hfil# \hfil&#&\hfil#\cr Why? How primitive it may be, I would like to use \halign now and then. Hans van der Meer

One of these can be avoided with a change in the setup for footnotes but not the other without destroying the layout of the footnote text. One problem is the way how context places the footnote number in front of the text, by default context uses the \llap command to move the number into the left margin but this prevents also the protrusion of the opening quote. You can avoid this problem when you change the footnote setup to \setupnotation[footnote][alternative=margin]. <example> \definefontfeature[default][default][expansion=quality,protrusion=quality] \setupbodyfont[modern] \setupalign[hanging] \showframe[text][text] \starttext »Text« \noindent\hbox to 0pt{}»Text« \noindent\hbox to 0pt{\hss}»Text« \stoptext </example> The second problem which prevents the opening quote to protrude are the struts which are added by context at the begin and end of the footnote content and there is no way to disable them because they are needed to have proper spacing between the individual footnote texts on the same page. <example> \definefontfeature[default][default][expansion=quality,protrusion=quality] \setupbodyfont[modern] \setupalign[hanging] \showframe[text][text] \starttext »Text« \strut »Text« \stoptext </example> In the example below where I took care of these two problems (don’t take care of \begstrut in this way in your real document because it will cause many problems, it’s just for educational purpose) to show you this is what caused the unwanted output. <example> \definefontfeature[default][default][expansion=quality,protrusion=quality] \setupbodyfont[modern] \setupalign[hanging] \showframe[text][text] \setupnotation[footnote][alternative=margin,align=hanging] \starttext \let\begstrut\relax First Footnote.\footnote{»\input{ward}«} Second Footnote.\footnote{»\input{ward}«} \stoptext </example> Wolfgang

metafun
by Herbert Voss 24 Mar '16

24 Mar '16

It is a hard job to understand how all works ... I tried to create the first example of the documentation "Page 257 Anchors and layers", but failed with mkii and iv. The page is created, but without the graphical elements. Not using \startbuffer--\stopbuffer makes no difference. MTXrun | current version: 2010.07.30 11:35 Herbert \starttext \section {Anchors and layers} \startbuffer[a] \setMPpositiongraphic{X-1}{mypos:arrow}{to=X-2} \setMPpositiongraphic{X-2}{mypos:arrow}{to=X-3} \stopbuffer \startbuffer[b] In a previous section we saw that some \hpos {X-1} {words} were \hpos {X-2} {circled} and connected by an \hpos {X-3} {arrow}. As with most things in \CONTEXT, marking these words is separated from declaring what to do with those words. This paragraph is keyed in as: \stopbuffer \getbuffer[a,b] \stoptext

Setting expansion depth limit for metapost
by Michal Suszko 18 Feb '16

18 Feb '16

I'm preparing quite long presentation -- nearly 3000 sides, 900 figures (500 distinct PNG files). I'm using ConTeXt MkIV installed using minimals (2010.03.12 19:49). Recently I'm hitting MetaPost capacity limit on expansion depth: !mplib : mp terminal: ! MetaPost capacity exceeded, sorry [expansion depth=10000]. Increasing expand_depth in texmf.cnf and regenerating formats with context --make doesn't help. expansion depth is still at 10000 in error message. texmf.cnf in texmf-local I've changed is reported by context as first one in log line starting with "mkiv lua stats : used config path" What am I missing?
