Alignment/line break in a TABLE cell
by Mari Voipio 19 May '16

19 May '16

Hi, I have a little problem with a table. It works fine otherwise, but in the first column the box and the number should be on the same line. This goes right with 3a, but all the other ones place the box on the first line and the number on the second. Widening column 1 doesn't help. How do I force the number to stay on the same line with the box? \starttext \bTABLE \setupTABLE[r][odd][background=color,backgroundcolor=gray] \setupTABLE[r][each][bottomframe=off,topframe=off,rightframe=off] \setupTABLE[c][1][leftframe=off,width=2cm] \bTR \bTD \externalfigure[box3mm] 1 \eTD \bTD Pharma refractometer PR-43-PC \eTD \eTR % \bTR \bTD \externalfigure[box3mm] 2 \eTD \bTD \eTD \eTR % \bTR \bTD \externalfigure[box3mm] 3\crlf \externalfigure[box3mm] 3a \eTD \bTD \eTD \eTR % \bTR \bTD \externalfigure[box3mm] 4 \eTD \bTD \eTD \eTR \eTABLE \stoptext Mari PS. I don't think it is relevant here, but my ConTeXt is relatively new, 2016.04.17.

ConTeXt commands
by Meer, Hans van der 18 May '16

18 May '16

What is the latest edition of "ConTeXt commands"? The one I have here is dated July 1,2015. It is missing some commands however: \setupnotes to name an example. I find it a very handy document, but alas it is not standard in the contextbeta distribution as for example the LuaTeX manual in latest editiion is. Otherwise, where is it to be found? It seems absent from the Contextgarden homepage. Hans van der Meer

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

Graphics not being aligned correctly in natural tables
by cryo shock 17 May '16

17 May '16

Hello fellow ConTeXt lovers, I am having trouble with placing graphics in between \bTD and \eTD. I am using the \externalfigure to do so which works great. The problem is that they aren't being aligned at all when i use \setupTABLE[align={middle,lohi}] whereas text is being aligned perfectly in the middle of each cell. I found out that one can use \dontleavehmode\externalfigure to force alignment, which als works. But when I use \dontleave... the graphic isn't being placed perfectly in the middle but slightly a little bit more to the top of the cell. It's not a real problem for me but since everything looks great in the document, the slightly to the top moved graphics bother me somehow. Does anybody know a workaround maybe? Greets, Sebastian

How to export to PDF-A?
by Matija Šuklje 17 May '16

17 May '16

Dear ConTeXt community, There is a document I wrote in ConTeXt that I’m required to submit in PDF-A. I’ve already done my RTFM homework: http://wiki.contextgarden.net/PDF/A including links in it, but can’t figure out how to apply it in practice. So far I’ve identified two possible issues: • I haven’t set it right in the source https://gitlab.com/fla-llm-thesis/fla-llm-thesis/ https://gitlab.com/context-modules/pful • The ICC profiles aren’t in the right place – I can’t figure out where they should be on a Linux system. Help much appreciated! cheers, Matija -- gsm: tel:+386.41.849.552 www: http://matija.suklje.name xmpp: matija.suklje(a)gabbler.org sip: matija_suklje(a)ippi.fr

definebodyfontenvironment
by Meer, Hans van der 16 May '16

16 May '16

I like to execute this statement \definebodyfontenvironment[somevalue] in order to avoid lots of error messages as such: fonts > bodyfont '8.0pt' is defined (can better be done global Is this definebodyfontenvironment macro fully executed each time it is called or does ConTeXt remember and execute it once only?

problem with \setupdelimitedtext
by Alan Bowen 16 May '16

16 May '16

In the following, the indentation using \startblockquote is twice what it should be: \setupdelimitedtext [blockquote] [before={\blank[small,fixed] \setupnarrower[left=1.5pc,right=0pc] \startnarrower[left,right] \noindentation}, after={\par\stopnarrower \blank[small,fixed] \noindentation}] \starttext \input ward \setupnarrower[left=1.5pc,right=0pc] \startnarrower[left,right] \input ward \stopnarrower \startblockquote \input ward \stopblockquote \stoptext What have I missed?

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

With TeX, change may start as with Lua, only some better syntax for text input. I experimented a bit with giving Guile a C++ API, and then then there is a problem with that that C++ is statically typed whereas Guile is dynamic. For example, Guile does not distinguish statically between different types of numbers: integers, rationals, etc, so the proper way from the point of C++ is to only have open number type. But static typing is important in optimization. And giving implement traditional function syntax on top of Guile does not work well, because (f, x_1, …, x_k) does not correspond semantically exactly to f(x_1, …, x_n). And there is a problem with the Scheme strict evaluation. So such issues lead towards to the design of a new language, rather than relying on an already existing.
