What alternative for scantokens( "btex " & texcommands & " etex")?
by Gerben Wierda 30 Mar '20

30 Mar '20

I’m trying in METAPOST to build a command to pass on to ConTeXt using btex/etex. picture p; p := scantokens( "btex " & texcommands & " etex”); with texcommands a variable that holds a string of TeX commands doesn’t work. The METAPOST parser complains about not finding etex. I’m using MetaFun actually. An example string in texcommands would in the end be something like string texcommands; texcommands := "\type-{Hello}, [World]!-"; Minimum example of my vardef that fails (the outcommented alternative to the scantokens line works and typesets “{Hello}, [World]!”): vardef makeTeXLabel( expr w, h, name) = show "NAME:", name; save p; picture p ; save s; string s; s := "btex " & name & " etex"; show "SCAN:", s; p := scantokens s; %p := btex p := btex \type-{Hello}, [World]!- etex; p enddef; Log: metapost log > >> "NAME:" metapost log > >> "My Application (Component)" metapost log > >> "SCAN:" metapost log > >> "btex My Application (Component) etex" metapost log > ! No matching 'etex' for 'btex'.. metapost log > <to be read again> metapost log > ; metapost log > makeTeXLabel->...x";show"SCAN:",s;p:=scantokens.s; metapost log > save.b;path.b;b:=boundingb... metapost log > <argument> ...(53),("My Application (Component)")) Thanks in advance, G

infinite loop with a huge document
by Pablo Rodriguez 30 Mar '20

30 Mar '20

Dear list, I’m afraid I have a huge document (combination of more than 80 individual documents) that triggers an infinite loop. All of them are Markdown sources that I convert to HTML4 and compile with ConTeXt latest. Individual documents compile fine, in about 3 or 4 runs. The single document goes always for the maximum number of runs. There were 9 runs, which is the default number. I set "--runs=30" and compilation ran through 30 cycles. So I use now "--runs=5". The document is huge and its compilation process is complex. Is there any way in which I can investigate what triggers the compilation in endless cycles for this document? Many thanks for your help, Pablo -- http://www.ousia.tk

Box of certain width (and height?) containing a paragraph of text?
by Gerben Wierda 30 Mar '20

Does ConTeXt have a command to create a (non framed) box from a line of text, where the text is typeset as a paragraph inside a box of certain size? G

placelistofsynonyms without tabulate
by Benjamin Buchmuller 30 Mar '20

30 Mar '20

Following Aditya’s recommendation on making a glossary with ConTeXt (https://tex.stackexchange.com/questions/152248/make-a-glossary-with-context) and have looked through several older and newer manuals under “abbreviations” and into the source. However, I cannot figure out if there is a simple way to define my own command to achieve the following: \definesynonyms[glossary][glossaries][\fullgloss]%[#4] % I wonder also what #4 is supposed to do? \setupsynonyms[glossary][headstyle=bold] \glossary[US]{United States}{The US is a country in the Americas.} \glossary[UK]{United Kingdom}{The UK is a country in Europe.} % CURRENT RESULT (guessing from what I understand from the source this is converted internally to): \placelistofglossaries \starttabulate[|||] \NC {\bf United Kingdom} \NC The UK is a country in Europe. \NC \NR \NC {\bf United States} \NC The US is a country in the Americas. \NC \NR \stoptabulate % DESIRED RESULT \unexpanded\def\myglossary#1#2#3{{\bf #1}#2} % or similar \placelistofglossaries[command=\myglossary] {\bf United Kingdom.} The UK is a country in Europe. Nice would be even if this could be indented at some point, but tastes may vary on indention for sure. {\bf United States.} The US is a country in the Americas. % or using itemize etc. I am aware that \placelistofsynonyms has a command=... option, but it doesn’t do anything for me. Also, the location=inmarigin option (which I suppose could be used to tweak the desired result in a way) stopped working in MKIV (?) and I can see in the source that it has a “fixed” assignment to location=left. Any hints very welcome. :)

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
