Installing Modules with ConTeXt LMTX
by Sebastian Miele 06 Jun '20

06 Jun '20

I want to try the t-letter module. I have a fresh install of ConTeXt LMTX from today. The page https://wiki.contextgarden.net/Modules has sections "Installation by hand" and "ConTeXt standalone", but no section on ConTeXt LMTX. The section on ConTeXt standalone mentions a --modules switch to first-setup.sh in order to include modules. This cannot work with the install.sh from ConTeXt LMTX, as it does not pass any command line arguments to mtxrun. install.sh does have an empty by default variable LMTXEXTRAS at the top, which is passed as --extras="$LMTXEXTRA" to bin/mtx-install.lua near the bottom of the script. However, setting LMTXEXTRAS=t-letter seems to not work. Searching through the bin/mtx-install.lua for "modules" and "extras" reveals that most probably neither flag is handled at all. However, the helpinfo variable in bin/mtx-install.lua does mention the modules flag, but not the extras flag. Is there a way to install modules in ConTeXt LMTX not by hand?

\frac and vertical spacing issue in mathfractions
by Alan Bowen 06 Jun '20

06 Jun '20

In the current beta ( LuaMetaTeX, Version 2.06.05), \m{\frac{28}{8\times29}} puts the numerator and denominator too close to the dividing line. Similarly for the variants of \frac and \over. \m{{28}\over{8\times29}} Alan

reduced space below chapter title
by jbf 03 Jun '20

03 Jun '20

Hi list, I am attempting to achieve, for every second chapter, to have only one line of space between the chapter title and the text that follows. I looked at the following example in the wiki: \setuppapersize[A6][A6] \setupbodyfont[8pt] \def\MyChapterCommand#1#2% {\vbox to 4cm\bgroup {#1\hskip.75em #2} \vss \egroup} \setuphead[chapter][header=nomarking, command=\MyChapterCommand] \starttext \chapter{test} \input tufte \stoptext and presumed that I could adjust that to something like 1cm instead of 4cm. The problem is that when I try to process the original example, I get a fatal error at the line which reads \chapter{test} \input tufte. I'm not sure why that error, but that aside, would the \def\MyChapterCommand approach suggested above be the right way to achieve my purpose? In other words, I want the text that follows the chapter title to follow immediately for specific chapters, rather than the considerable vertical space that follows the default setup for chapter titles.

This is one way (from the wiki): \startitemize[a][left=(,right=),stopper=] \item 1234 \item 5678 \item 9876 \stopitemize HTH, John

LMTX lua xml interface: xml.tag()?
by Gerben Wierda 02 Jun '20

02 Jun '20

According to the mkiv manual, there is a \xmltag which I think should translate to xml.tag() in lua. But while xml.name() works, xml.tag() fails: attempt to call a nil value (field 'tag') Should xml.tag() work? G

spacing between chapters in TOC
by jbf 02 Jun '20

02 Jun '20

Hi list, I want my table of contents to look like: Chapter 1 section 5 section 10 section 15 In other words with section items indented. I presumed I would need to do something with \setuplist[section]. I know how to control interline distance, whitespace, but in this instance, not indentation of certain lines in a toc. I tried \setuplist[section][indenting=yes] and even indentation=yes in the hope that existed. It doesn't, at least not used this way. But it must be simple enough to achieve? Julian

Two questions concerning numerals in ConTeXt
by Jairo A. del Rio 02 Jun '20

02 Jun '20

Hi, everybody. I expect you to be safe. I found the following issues. *First. *The following gives wrong results for Spanish numbers \mainlanguage[es] \starttext \convertnumber{words}{100} %Prints "ciento" instead of "cien" \convertnumber{words}{2000000} %Prints "dos millón" instead of "dos millones" \stoptext I've read other messages from the list concerning numerals and I found the following in core-con.lua [100] = "ciento", [1000000] = "millón", [1000000000] = "mil millones", [1000000000000] = "billón", "cien" (for numbers from 100 to 199) and "millones" (for numbers from 2 000 000 to 999 999 999 999) are missing (no issue with "billón", as Lua doesn't seem to handle too big numbers natively). *Second. *I tried to use Unicode tally marks (U1D377 and U1D378): \definefont[tallyfont][babelstonehan] %\mainlanguage[es] \startluacode userdata = userdata or {} userdata.tallymarks = function(n) local one = [[\char"1D377]] --Also tried "\u{1D377}" local five = [[\char"1D378]] --Also tried "\u{1D377}" return string.rep(five, (tonumber(n)//5))..string.rep(one, (tonumber(n)%5)) end \stopluacode \def\tallymarks#1{\ctxlua{userdata.tallymarks("#1")}} \starttext \tallyfont \tallymarks{47} \stoptext This works on Lua 5.4.0 (rc4) interpreter, but it doen't on ConTeXt LMTX nor LuaTeX and codes are printed instead (1D3781D378...). What is weird considering that \starttext \char"1D377 \stoptext gives the right output with an adequate font. Btw, I know about the Metafun alternative described on the book, but I'd prefer to use Unicode when possible. Thank you in advance. Jairo :D

Writing the caption above figures in combinations
by Otared Kavian 01 Jun '20

01 Jun '20

Hi all, Is it possible to write the individual captions for each element of a combination of floats above it, while the caption for the figure appears below? \startplacefigure[title={A combination of three figures}] % this title appears below the figure \startcombination[3*1] {\externalfigure[image-1.pdf][width=4cm]}{a} % a appears above image-1 {\externalfigure[image-2.pdf][width=4cm]}{b} % b appears above image-2 {\externalfigure[image-3.pdf][width=4cm]}{c} % c appears above image-3 \stopcombination}{} \stopplacefigure I tried to define a new float, say myfigure, which has captions below and then I tried \setupcaptions[location=top] and \setupcombinations[location=top] but this does not work… Thanks for any help: Otared
