How to make page break & headers in XY arrangements?
by Mojca Miklavec 30 Mar '20

30 Mar '20

Hi, Stupid question: what's the proper way to introduce an actual page break and put some header on the paper holding the XY arrangement of smaller pages? I know I can create the second document which includes the first one and adds page numbers on top, but I'm sure there's a more elegant way to achieve the same. Thank you, Mojca \setuppapersize [XY][A4] \setuppaper [topspace=10mm,backspace=10mm,dx=0mm,dy=0mm,nx=5,ny=13] \setuplayout [page] [topspace=2mm,backspace=2mm] \setuplayout [page] \setuplayout [location=middle] \setuparranging [XY] \showframe \setupbodyfont [8pt] \def\somecontent#1{\startpagemakeup #1 \stoppagemakeup} \starttext % I want to mark the page with label numbers \setupheadertexts[1][1][1][1]% \dorecurse{50}{\somecontent{Label ONE}} % I want an actual page break here \page \setupheadertexts[2][2][2][2]% \dorecurse{70}{\somecontent{Label TWO}} \stoptext

conditional for undefined references
by Pablo Rodriguez 30 Mar '20

30 Mar '20

Dear list, consider the following sample: \setuppapersize[A8] \starttext \ConTeXt: \in[seac] Is it defined?: \doifelse{\in[seac]}{??}{undefined}{defined} \Lua: \ctxlua{context([[{\in[seac]}]])} Is it defined?: \startlua if [[{\in[seac]}]] == "??" then context("undefined") else context("defined") end \stoplua \stoptext Is there a way to deal with undefined references? I mean, I need a conditional to handle undefined references. Why do I have undefined references in my documents? Well, I have almost 90 (Markdown) documents that I need to compile as single documents and also as one document. When compiling as single documents, there are a few references to other documents. This is the reason why they are undefined. Any chance to be able to catch a "??" output (or \dummyreference) from "\in[reference]"? Many thanks for your help, Pablo -- http://www.ousia.tk

Different behaviour of textcommand (setupcaption+startplacefigure)
by Tomas Hala 29 Mar '20

29 Mar '20

Hi all, I noticed the difference in behaviour of textcommand which depends on the location: for top, bottom and page the \crlf (see MWE) is applied while for the left and right not even if other values (\red, any-text) are used as expecterd. How could I activate the textcommand=\crlf for location=right? (The line break appears only the width of the figure becomes too small.) Tested with TL2019 and with version from Mar 6, 2020. Best wishes, Tomáš %% MWE: \starttext \setupcaption[figure][textcommand=\crlf] \startplacefigure[location=top,title=Cow] \externalfigure[cow.jpg][height=4cm] \stopplacefigure \input knuth \setupcaption[figure][textcommand=\crlf] \startplacefigure[location=right,title=Cow] \externalfigure[cow.jpg][height=4cm] \stopplacefigure \input knuth \stoptext

Nodes module for commutative diagrams etc
by Weber, Matthias 29 Mar '20

29 Mar '20

Dear list, I need to typeset a handful of simple commutative diagrams like the one below, and I found the nodes manual by Alan that has exactly what I want. But what is the incantation to load the module, or am I missing something else? Thanks, Matthias \starttext \startMPcode path p ; p := fullsquare scaled 3cm ; nodepath = p ; draw node(0,"\node{$G(X)$}") ; draw node(1,"\node{$G(Y)$}") ; draw node(2,"\node{$F(Y)$}") ; draw node(3,"\node{$F(X)$}") ; drawarrow fromto.bot(0,0,1, "\nodeSmall{$G(f)$}") ; drawarrow fromto.top(0,3,2, "\nodeSmall{$F(f)$}") ; drawarrow fromto.rt (0,2,1, "\nodeSmall{$η_Y$}") ; drawarrow fromto.lft(0,3,0, "\nodeSmall{$η_X$}") ; \stopMPcode \stoptext

Space around comma in math mode

Hi, I am using $ context --version mtx-context | ConTeXt Process Management 1.03 mtx-context | mtx-context | main context file: /opt/context/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2020.01.30 14:13 mtx-context | main context file: /opt/context/tex/texmf-context/tex/context/base/mkiv/context.mkxl mtx-context | current version: 2020.01.30 14:13 I am seeing some space in the PDF output when using comma's in math mode. The space is between the "," and the "2". How can I eliminate this extra space ? \starttext Some text $1,23$ \stoptext Thanks

How do I handle strings with " characters in it in METAPOST?
by Gerben Wierda 29 Mar '20

29 Mar '20

I am using MetaFun (Lua code) to create METAPOST commands from an XML file. One of the issues I am running into that in METAPOST I have to handle strings with " characters in them and METAPOST doesn’t like those. The argument using the string Foo "Bar” Foo turns into someCall( "Foo “Bar” Foo”) I guess I have to change the string into something with explicit character codes for the " characters, maybe? In a later stage, these strings will be typeset by the ConTeXt side of things so they fit into a certain area within the METAPOST picture. What is my best approach? G

I could use some ideas for a strategy to get these kind of labels in a METAPOST picture
by Gerben Wierda 29 Mar '20

29 Mar '20

I have strings I get from an XML that I want to turn into labels for objects in a METAPOST picture (using MetaFun). These strings can have arbitrary characters (like accents) and some characters are coded. Examples of how these are coded: My "Application” Fünction [My] Application (Component) Business & service Besides the text, I know what the intended size (e.g. 10) and style (e.g. bold or italics) is. I have the string and I have a size of a box it needs to be fitted in and I have set a default font. Preferably, I’d like to code these in a box of the aspect ratio of the box it needs to fit in. So, for instance, I have a box that is 50 (high) by 130 (wide) and - if the text fits in the box, just typeset it. Break the words (yes or no) - if the size set does not fit in the box, make it smaller so it fits. Initially this is optional as the boxes will be of the size in which the text fits. - I might want to use some pattern to split it into multiple lines. E.g. if the last part of the string is “(some text)” put it on a last line by itself and if the first part of the string is “[some text]” put it on a first line by itself I am using Lua to generate METAPOST which are written by ‘context’ commands. I am not that experienced and I am looking for tips on a strategy to do this. Thanks in advance, G
