annotated equations
by Henning Hraban Ramm 18 Nov '22

18 Nov '22

Here’s an interesting example for annotated equations, done with LaTeX/TikZ: https://mastodon.social/@sibin/109349703357749846 I guess something similar is possible with node anchors in ConTeXt/MetaPost? Hraban

Do environment files add implicit \starttext ... \stopttext
by denis.maier＠unibe.ch 18 Nov '22

18 Nov '22

Hi, if I process an XML buffer, I've noticed I need to wrap the \xmlprocessbuffer in a \starttext ... \stoptext pair. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \startbuffer[test] <?xml version='1.0' standalone='yes?> <document> a paragraph of text another paragraph of text </document> \stopbuffer \startxmlsetups xml:demo \xmlsetsetup{\xmldocument}{document|p}{xml:*} \stopxmlsetups \xmlregistersetup{xml:demo} \startxmlsetups xml:document \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:p \xmlflush{#1}\endgraf \stopxmlsetups \starttext \xmlprocessbuffer{test}{test}{} \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% However, if I have the XML and the setups in dedicated files, there seems to be no need for \starttext ... \stoptext. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% text.xml <?xml version='1.0' standalone='yes?> <document> a paragraph of text another paragraph of text </document> %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% setups.tex \startxmlsetups xml:demo \xmlsetsetup{\xmldocument}{document|p}{xml:*} \stopxmlsetups \xmlregistersetup{xml:demo} \startxmlsetups xml:document \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:p \xmlflush{#1}\endgraf \stopxmlsetups %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Running context text.xml -environment=setups.tex gives me a proper PDF without errors. Therefore my question: Does the use -environment automatically wrap the processed file in \starttext ... stoptext ? If not, what's the reason for this behaviour? Am I missing something? Best, Denis

\autoinsertedspace fails following \nbsp under LMTX
by Rik Kabel 17 Nov '22

17 Nov '22

ConTeXt ver: 2022.11.14 22:58 LMTX on W11 x64 I have been testing the recently added \autoinsertedspace, and I found an odd failure. The following compiles with \nbsp commented as shown, but once that line is active, the compilation fails: lua error: callback error: ...MTX/tex/texmf-context/tex/context/base/mkxl/font-hsh.lmt:151: table index is nil It fails differently in MkIV (but it is nice to see that the new command has been backported): luatex warning > node filter: error: ...MTX/tex/texmf-context/tex/context/base/mkiv/node-nut.lua:380: Attempt to node.direct.remove() a non-existing node %<------------------------------------------------------ \starttexdefinition unexpanded New \dodoublegroupempty \doNew \stoptexdefinition \starttexdefinition doNew #1#2 \removeunwantedspaces \ (#1|–|#2) \autoinsertedspace \stoptexdefinition \starttext ABC 0\New{123}{456} 789 ABC % \nbsp 0\New{123}{456} 789 \stoptext Am I doing something wrong here? \nbsp is needed to prevent improper line breaks. -- Rik

Dear list, I like to use the Iosevka as mono typeface. It worked in the past, but sadly context crashes now with the following error. fatal error: /font-dsp-macro.lua:2336: attempt to index a nil value (local 'sequence') Plese see MWE below.

How to break margin notes across page breaks?
by Joel 16 Nov '22

16 Nov '22

How can I allow margin text to break across the page breaks? I have a document with many \inmargin code. The problem I'm finding is that sometimes I have a lot of items in the margin. I hope this margin details can break across the page and continue onto the next page. The problem is instead it just runs off the print boundaries of the page. See this sample code for an example: \starttext \input knuth \inmargin{\input knuth } \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \stoptext How can I allow margin notes to break across pages instead of running off the page boundaries? --Joel

How to make a block of text narrower?
by Joel 15 Nov '22

15 Nov '22

I need to make a section of text in my document narrower, about .6666\textwidth. Basically the text has normal alignment and everything, just instead of filling \textwidth, its compressed so there is a larger white space to the right. I've tried dozens of things, but cannot get a good solution, every solution has strange other effects. The best thing that has worked so far is \setuplayout[width=3in] But the problem with this solution is then I cannot get it to return to the original settings afterward. --Joel

new upload
by Hans Hagen 15 Nov '22

15 Nov '22

Hi, I uploaded a new version. New is that we can apply hz to math, although currently we have configured it as experiment. \setupbodyfont[pagella] % \startluacode % fonts.expansions.vectors.math = { % [0x002B] = { 4, 0 }, -- + % [0x2212] = { 4, 0 }, -- - % [0x003C] = { 8, 0 }, -- < % [0x003D] = { 8, 0 }, -- = % [0x003E] = { 8, 0 }, -- > % [0x002F] = { 2, 0 }, -- / % [0x0028] = { 2, 0 }, -- ( % [0x0029] = { 2, 0 }, -- ) % [0x005B] = { 2, 0 }, -- [ % [0x005D] = { 2, 0 }, -- ] % } % \stopluacode \setupmathematics[hz=yes] \startbuffer \showglyphs \dorecurse{20}{\strut test $x + y/2 - w = 10$ }\unskip \stopbuffer \definecolor[tgreen][g=1,t=.5,a=1] \definecolor[tred] [r=1,t=.5,a=1] \startTEXpage[offset=5dk] \startoverlay {\ruledvbox to 5cm{\setupalign [tolerant,stretch]\tgreen\getbuffer\vss}} {\ruledvbox to 5cm{\setupalign[hz,tolerant,stretch]\tred\getbuffer\vss}} \stopoverlay \stopTEXpage \stoptext Normally an expansion factor is small and used for both stretch and shrink, but we can have them independendent. So, here we stretch rather extreme but don't shrink. \setupmathematics[hz=yes] only kicks in when we have hz enabled as alignment option. We can of course configure more 'stretchable symbols' but first we want to know if it makes sense at all. We can also imagine to disable it in specific cases.
