Hi! I have tried to run the following codeexample with no success \usemodule [gnuplot] \setupGNUPLOTterminal [context] [width=5in,height=2.5in,fontscale=0.9] \setupGNUPLOTterminal [tikz][width=5in,height=2.5in,fontscale=0.9] \starttext \startGNUPLOTinclusions set samples 400 set key left Left reverse \stopGNUPLOTinclusion \startGNUPLOTscript[myfunction] set zeroaxis set format y "%.1f" plot [-4:2][0:2] 1 t '' lt 0, exp(x) t '$e^x$' lt 1 lw 3 plot cos(atan(x))*sin(x) t '$\cos(\arctan(x))\sin(x)$' lw 3 lc 3 \stopGNUPLOTscript \placefigure{none}{\useGNUPLOTgraphic[myfunction][2]} \setupGNUPLOT [terminal=tikz] \placefigure{none}{\useGNUPLOTgraphic[myfunction][1]} \stoptext I’ve done the following in my LMTX installation mtxrun —generate context —make —all I am running gnuplot 5.2 installed via brew and I also checked that the terminal tikz is supported via set term So the module seems to be there Is there something more I need to do?

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
by w n 29 Mar '20

29 Mar '20

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

Just to be clear, the \setuplinewidth command sets only the value of the \linewidth register and not the rulethickness value itself. Most setups apply to the \linewidth value to rulethickness and this is why \setuplinewidth affects all commands which do this. \starttext \starttabulate[|r|l|][EQ={=}] \BC \tex{setuplinewidth[...]} \BC \tex{linewidth} \NC\NR \NC small \EQ \setuplinewidth[small] \the\linewidth \NC\NR \NC medium (default) \EQ \setuplinewidth[medium] \the\linewidth \NC\NR \NC big \EQ \setuplinewidth[big] \the\linewidth \NC\NR \NC 2pt \EQ \setuplinewidth[2pt] \the\linewidth \NC\NR \stoptabulate \stoptext Wolfgang

\setupinteraction v commas
by Tomas Hala 28 Mar '20

28 Mar '20

Hi all, I used the following MWE for creating the metainformation in PDF: \setupinteraction [title={a, b, c}, subtitle={a, b, c}, author={a, b, c}, keyword={a, b, c}, ] \starttext blah \stoptext While the title, subtitle and author contain the text without any change, in keyword all commas has been erased. Is this the expected behaviour? If yes, how could I write command inside? Best wishes, Tomáš

startcombination place reference left of images instead below
by Christoph Hintermüller 26 Mar '20

26 Mar '20

Hi When using refernece instead of column mode in start combination: Is it possible to tell context to place the reference label left or right of the picture/table etc and not below? Or do i have to use multiple columns and put reference manually and how? Following: +----------------------------+ a) | first comination element | +----------------------------+ +----------------------------+ b) | second comination element | +----------------------------+ instead of: +----------------------------+ | first comination element | +----------------------------+ (a) +----------------------------+ | second comination element | +----------------------------+ (b) Best Xristoph
