styling references
by Pablo Rodriguez 28 May '21

28 May '21

Dear list, I have the following sample: \starttext \startitemize \dorecurse{15} {\item[\recurselevel]whatever} \stopitemize As exposed in \in{item}[9]... \stoptext How can I add style to the item reference (9)? I mean, how can I get “As exposed in item {\em 9}”? Many thanks for your help, Pablo -- http://www.ousia.tk

Luatex format error

Using TexLive 2021, I got the error below. How to fix it? What input file should one give? % context math_style.tex resolvers | formats | executing runner 'run luatex format': /usr/local/texlive/2021/bin/universal-darwin/luatex --jobname="math_style" --fmt=/Users/<name>/Library/texlive/2021/texmf-var/luatex-cache/context/a86c089b384a3076dc514ba966a1fac9/formats/luatex/cont-en.fmt --lua=/Users/<name>/Library/texlive/2021/texmf-var/luatex-cache/context/a86c089b384a3076dc514ba966a1fac9/formats/luatex/cont-en.lui --c:currentrun=1 --c:fulljobname="./math_style.tex" --c:input="./math_style.tex" --c:kindofrun=1 --c:maxnofruns=9 --c:texmfbinpath="/usr/local/texlive/2021/bin/universal-darwin" This is LuaTeX, Version 1.13.2 (TeX Live 2021) system commands enabled. ** Please type the name of your input file. **

setupindentations
by Hans van der Meer 28 May '21

28 May '21

This macro \setupindentations is mentioned in my ConText the manual from november 12, 2001. It seems to have disappeared. Is that so? Then why? What replacement? dr. Hans van der Meer

t-vim module: no highlighting for custom filetypes
by Nicola 28 May '21

28 May '21

For some reason, the vim module has stopped highlighting code associated to custom filetypes (it still works for built-in filetypes). For instance, typeset this: \usemodule[vim] \startvimrc[name=foo] set nocompatible set runtimepath+=~/foo/ \stopvimrc \definevimtyping[foo][ style={\switchtobodyfont[16pt,tt]}, directory=code/, syntax=foo, alternative=pscolor, vimrc=foo, ] \starttext \startfoo let while endwhile \stopfoo \stoptext The ~/foo/ directory contains ftdetect/foo.vim: au BufRead,BufNewFile *.foo setfiletype foo and syntax/foo.vim: if exists("b:current_syntax") finish endif syn case match syn iskeyword @,48-57,192-255,_ syn keyword fooKeyword let while endwhile hi def link fooKeyword Keyword let b:current_syntax = "foo" If I change `syntax=foo` to, say, `syntax=vim` in \definevimtyping then the code is highlighted. So, I suspect that I am not configuring the runtimepath correctly. Any idea how to fix this? I am using the latest LMTX to which I have added modules as explained here: https://wiki.contextgarden.net/Modules#ConTeXt_LMTX t-vim VERSION reads 2021.03.01. Nicola

no leavevmode
by Hans van der Meer 28 May '21

28 May '21

Why is there not implemented in \subsection a \leavevmode at the end of it? Here a minimal example showing that starting with the first word in an \hbox encounters vertical mode. Thus requiring a \leavevmode to put it on line with the following text. Whereas not starting with an \hbox does an implicite switch to horizontal mode. I can imagine that this behaviour could be confusing for users not well versed in the different behaviour of the horizontal and vertical modes. Therefore my question: Wouldn't it be wise to implement that \leavevmode? \startsubsection[title=TEST] \hbox{abc} def\crlf ghi jkl xyz \stopsubsection dr. Hans van der Meer

mathcolor attribute in MathML (mkiv)
by Duncan Hothersall 27 May '21

27 May '21

Hello list. I'm trying to use colour in some MathML formulae using the mathcolor attribute. It seems to have no effect on the output. I can see \applymmlmathcolor in the x-mathml.mkiv source but I can't see how to make it work. Does anyone have any pointers? (Does lmtx support this?) Thanks. Duncan

Hi. Is it still necessary to use setupitaliccorrection if we have switched to LMTX?

new upload
by Hans Hagen 27 May '21

27 May '21

Hi, I uploaded a new version of lmtx. Apart from some small fixes, the configuration file is hopefully okay too. I'm sure MF will check it. However, the biggest change is hidden. In traditional tex, inserts (used for footnotes) are implemented using a quadruple of registers. In context these come from the range 132-254 which is not used by normal allocations. The number is basically a sort of index. However, this box/dimen/count/skip memory model doesn't work well for (possible) extensions nor does the wrapped final (per page) box fit into the more extended regular box model (not that anyone will notice or abuse that, it's just that some features of boxes don't make sense in the perspective of inserts). Inserts are somewhat complex (and interwoven) and are also somewhat fuzzy when one wants to do checking when making progress on a page. We already deal with that in context in a reasonable way but I get the feeling that we can do better. This and the above are reasons to come up with a variant memory model that permits playing with additional features more easily. The existing storage model is stil there (after all it's tex) but for those willing to check the alternative, in page-ins.mkxl one can uncomment % \insertmode\plustwo and remake the format. I rejected a mixed mode model because it makes the code ugly. Related mem grows on demand as with other mechanisms so there is no extra overhead involved. As a consequence I had to abstract some of the insert interface in context a bit more (because we use accessors instead of boxes) and hopefully I didn't forget one. We'll see. Once I'm confident with the new approach we'll switch to that (low level) interface model and can progress. Because users don't use inserts directly themselves not much harm can be done.

Unnecessary loading of lm-mono
by Rik Kabel 26 May '21

26 May '21

For a few revisions now, I have seen the following as the very first line of log files. It is not coming from my document. Is anybody else seeing it? fonts > beware: no fonts are loaded yet, using 'lm mono' in box Here is an example document that generates it: \setupbodyfont[libertinus,10pt] \starttext Hello world! \stoptext It seems harmless, but it does result in loading an un-needed font. mkiv lua stats > loaded fonts: 4 files: lmmono10-regular.otf, libertinusmath-bold.otf, libertinusmath-regular.otf, libertinusserif-regular.otf -- Rik
