Dear all, I have a legacy project that I shall convert to a new ConTeXt project. There are a lot of Graphviz dot-files. What shall I do with these? Any hints? juh -- Autoren-Homepage: ......... http://literatur.hasecke.com Satiren & Essays: ......... http://www.sudelbuch.de Privater Blog: ............ http://www.hasecke.eu Netzliteratur-Projekt: .... http://www.generationenprojekt.de

colors and contours in luametafun
by Jacob Kauffmann 23 Jun '22

23 Jun '22

Dear list, I am a huge fan of the new metafun interface. Hans asked for luametafun requests, so here are a few. - color by value in lmt_surface We want to show a surface plot of a function where the color indicates the function value (instead, or in addition to a light source). The easiest would be to have variable cf for the brightness factor (as it is), and in addition variables such as zt, minz, maxz, akin to the color formatter for lmt_contour. This becomes handy when colors are to be aligned with function values (e.g. negative = blue, zero = white, positive = red, see MWE attached). - controlling line levels in lmt_contour It would be convenient if certain levels could be set by the user. E.g. to make sure the zero level contour line is included. The user interface could potentially take a list, levels = { -1, -.5, 0, .5, 1 }, of contour level lines. See MWE attached. From my understanding marching squares can do that. A possible reference implementation could be QuadContourGenerator [1] in matplotlib, a bit of description can be found in [2]. - colormaps Contour plots often use rather complex colormaps, such as jet, rainbow or veridis. They are optimized for perceptual resolution, color blindness, screen/print or certain use cases. The functionality is already there, but from a user's perspective, it would be much easier if some of these were provided by the interface. The interface could be color = "colormap('jet')(l/n)". Indeed, these are useful in other use cases as well, such as bar charts, surface plots or shades. One rudimentary example is in the attached file. - number of levels in lmt_contour (potential bug) The number of levels is different from the user's input. Depending on the output range it can be lower or higher (see MWE attached). Cheers, Jacob Kauffmann [1] https://github.com/matplotlib/matplotlib/blob/96ff1146ad053c5c7481efd9de039… [2] https://github.com/matplotlib/matplotlib/blob/96ff1146ad053c5c7481efd9de039…

\placelistofabbreviations - solved
by jbf 20 Jun '22

20 Jun '22

The setup I offered in the previous email was all correct, but in a large project like a dictionary with 26 or more components there can always be something else that goes wrong! Component 'D' had an extra { in it, but oddly enough the component was compiling, except that I picked up an error message despite the fact it had compiled correctly. That one error was enough to throw things out of kilter, including the \placelistofabbreviations in an earlier component. Sorry for the noise Julian

\placelistofabbreviations in project structure?
by jbf 20 Jun '22

20 Jun '22

Hi, I wonder what I might be doing wrong for \placelistofabbreviations not to work in a project. Everything else about \definesysnonyms and indeed the project is working, but I seem unable to place the list correctly in the component that is intended to list all abbreviations. The main environment file for the project contains the definitions. e.g. \definesynonyms[abbreviation][abbreviations][\infull] \setupsynonyms[abbreviation][synonymstyle=\em] \abbreviation[adjp] {adjp.} {adjectival phrase} All dictionary components (A-Z) call on the main environment file where the above is defined and give me the correct result if I write \adjp\ or \infull{adjp} in any one of them. My MWE below for the (as yet not working) abbreviations component that contains the placelist command: \startcomponent 04_abbreviations \project project_Dictionary \startchapter[title={Abbreviations}] \placelistofabbreviations[criterium=all] \stopchapter \stopcomponent According to me that should work, but all I get is the chapter title. I also tried adding a state=start in case that was needed, but it did nothing. Julian

Dear list, I have the following sample: \setuppapersize[A6] \definelinenote[otherlinenote] \setupnote[otherlinenote] [compress=yes] \startsetups[line:notes] \setupinterlinespace[line=2.9ex] \stopsetups \setupnote[linenote] [paragraph=yes, compress=yes, compressmethod=separator]% \setupnotation[linenote][alternative=serried, width=broad] \starttext \startlinenumbering \dorecurse{3}{\subject{Heading\linenote{title}} \dorecurse{2}{text\linenote{some text}\linenote{another text}\par}} \stoplinenumbering \stoptext How can I get headings added to the line numbers? Many thanks for your help, Pablo

\setuplist only for bodypart
by Pablo Rodriguez 18 Jun '22

18 Jun '22

Dear list, sorry for the very basic question, but I cannot find the way to do it. Imagine I have the following command: \setuplist [chapter] [alternative=d] But I only want for sectionblock bodypart (nof for frontpart, backpart or the appendices). I have enclosed in: \startsectionblockenvironment[bodypart] ... \stopsectionblockenvironment I have also tried: \setuplist [bodypart:chapter] [alternative=d] But nothing changed. Which is the right way to do it? Many thanks for your help, Pablo

How to print a random whole number between x and y?
by Joel 17 Jun '22

17 Jun '22

I was using this code for a long time in my document. I have a PDF with 10 pages, and this would randomly display one of those pages: \ctxlua{math.randomseed( os.time() )} \getrandomnumber \n {1} {10} \placefigure[force, none]{}{\framed[frame=off]{\externalfigure[comic.pdf][page=\n, width=\textwidth]}} For reasons I cannot understand, after an update of ConTeXt, the code no longer works, though trying to reduce it to a minimum working example it works, so I cannot figure out what is wrong in my code. Undefined control sequence <argument> ...domseed( os.time() )} \par \getrandomnumber \n {1} {10} \par \placefigure... \doifsomething #1->\edef \m_syst_string_one {#1 }\ifx \m_syst_string_one \emp... \event ... {#6}{{\bf #6}} \par \doifsomething {#7} {#7 } \par \doifsomething ... Is there another solution for generating a random whole number between 1 and 10? --Joel

Custom engine settings in AUCTEX
by Jan-Erik Hägglöf 17 Jun '22

17 Jun '22

HI! I’ve been trying out Doom-Emacs and when I open a ConTeXt file i want the engine point to my LMTX installation. /Users/jan-erikhagglof/context/context-osx-64/tex/texmf-osx-64/bin/ is the path to my install on my Macos Monterey. How can this been customized? Its a bit confusing reading the AUCTEX manual so maybe someone has a working config already? Thanks in advance Jan-Erik

lmtx installation paths not working

Hello list, I cannot make fresh install of lmtx to work. The structure after unzipping: C:\data\context\bin\beta C:\data\context\bin\beta\bin C:\data\context\bin\beta\tex C:\data\context\bin\beta\tex\texmf C:\data\context\bin\beta\tex\texmf-cache C:\data\context\bin\beta\tex\texmf-context etc. First compilation of texfile is not working, so mtxrun --generate is the friend.
