Overlays as background in textbackground
by Marco Patzer 18 May '16

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

right to left direction for itemize columns
by Bou Salim 28 Apr '16

28 Apr '16

I have posted a question in tex stack exchangeCustomize right to left list in context <http://tex.stackexchange.com/questions/294627/customize-right-to-left-list-…> My aim is to obtain right to left items arranged in multi-column, if I use \startitemize [s,columns,three] [margin=1em] the result is three column where first column start from left side of page, but I want it to start from right side of page. I can use \startcolumns[direction=left]\startitemize \item First \item Second \item Third \stopitemize \stopcolumns but I think it look better if there is a key direction=left for the \startitemize environment such as used in columns environment.

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

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

footnotes and links
by Hans Hagen 02 Mar '16

02 Mar '16

Hi, The beta has a bit adapted note interactivity (rather tricky as these inserts have their own weirdness) % \setupnotes[interaction=no] % \setupnotes[interaction=yes] % \setupnotes[interaction=text] % \setupnotes[interaction=number] \setupnotes[interaction=all] \setupinteraction[state=start,focus=width,option=name] % option probably not needed \starttext \dorecurse{10}{note #1\footnote[reference:#1]{\input ward \input tufte\relax} } \par \goto{OEPS 3}[reference:3] \goto{OEPS 10}[reference:10] \stoptext I can't check much (as I don't know what to expect, but there is no real definition of qualitative behaviour there anyway) but this is what can be done. I have no clue to what extent complex interactions between footnote splitting and their content can interfere.

Vertically centered text in each page
by Nicola 02 Mar '16

02 Mar '16

Inspired by Aditya's "make a presentation in 40 commits" example, I have defined my own environment for slides. A part of it looks like this: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \startreusableMPgraphic{header:background} fill OverlayBox leftenlarged BackSpace rightenlarged CutSpace topenlarged TopSpace withcolor OverlayColor ; setbounds currentpicture to OverlayBox enlarged max(BackSpace,CutSpace) ; \stopreusableMPgraphic \defineoverlay[header:background][\reuseMPgraphic{header:background}] \define[2]\MySlide{\framed[ frame=off, background=header:background, backgroundcolor=orange, width=\textwidth, align=flushleft ]{#2}} \definehead[slide][subject] \setuphead[slide][ style=\ssb, command=\MySlide, color=white, page=yes, ] \starttext \startslide[title={Slide One}] \vfill text \vfill \stopslide \startslide[title={Slide Two}] \vfill text \vfill \stopslide \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% As you see, I am using \vfill to have the text vertically centered. How do I setup the slide command to do that by default? I have tried putting {before,after,beforesection,aftersection}=\vfill in various combinations in \setuphead, but I cannot obtain the desired effect. Related to the code above, I have another question: if I remove the comma after page=yes, slides are not split into different pages. Is it normal that a comma is required at the end of an argument list? Nicola
