Converting footnotes to endnotes
by Idris Samawi Hamid ادريس سماوي ح امد 05 Jun '21

05 Jun '21

Dear gang, Generally, I do not use endnotes - see Robert Bringhurst's criticisms of endnotes in typography - but a publisher is demanding them. Converting footnotes to endnotes must be quite simple yet I'm missing it: \setupnotation[footnote] [way=bychapter] % \setupnote[footnote] % [way=bychapter] \starttext \startsection[title={},reference={}] \input ward \startfootnote \input ward \stopfootnote{} \input ward \startfootnote \input ward \stopfootnote{} \stopsection \startsection[title={},reference={}] \input ward \startfootnote \input ward \stopfootnote{} \input ward \startfootnote \input ward \stopfootnote{} \stopsection \startsubject[title={},reference={}] \placenotes [footnote] \stopsubject \stoptext What's the best way to convert the above to endnotes? Thank you in advance! Best wishes Idris -- Idris Samawi Hamid, Professor Department of Philosophy Colorado State University Fort Collins, CO 80512

Hi♥ How do I get the quotes to potrude out in the left margin? For example in the following text, I want the "y" in "you are so" to be aligned with the "oh" in "oh hi there" and the "here" in "here here". \definefontfeature [default] [default] [protrusion=quality,expansion=quality] \setupalign[hz,hanging] \starttext oh hi there "you are so" here here \stoptext Also in the real text I'll also be using \definefontfamily [praise][serif][junicode] but, the above min via behavior I couldn't get to work at live.contextgarden

yscale not working
by Hans van der Meer 05 Jun '21

05 Jun '21

Why is there no effect of the yscale parameter in \externalfigure when the width-parameter is given? In the MWE it is the intention to stretch the height of the figure by a factor of two. But nothing happens. Leaving out the width does stretch the height, but then it becomes too wide. \starttext Test \tex{externalfigure} scaling - \ConTeXt\ \contextversion \blank \type{\externalfigure[test][width=0.50\textwidth]}\crlf \externalfigure[test][width=0.50\textwidth] \blank \type{\externalfigure[test][width=0.50\textwidth,yscale=2000]}\crlf \externalfigure[test][width=0.50\textwidth,yscale=2000] \stoptext dr.

Struggling with SQL!

Hi, I'm trying to get MySQL data access working but can't solve the issues I'm encountering. Part of my code looks like: \startluacode productsheet = productsheet or {} function productsheet.sqldatabase(database,user,password) productsheet:sql(database,user,password) end function productsheet:sql(db,us,pw) print("SQLDATABASE: database: " .. db) print("SQLDATABASE: username: " .. us) print("SQLDATABASE: password: " .. pw) local sql = require("util-sql") local presets = {database = db,username = us,password = pw,host= "localhost",port= 3306} local template = [[SELECT `nom`, `name_alias` FROM `llx_societe` WHERE `nom` = '%nom%' ;]] presets.id = "mysql" local data, keys = utilities.sql.execute {presets=presets,template=template,variables={nom = "Life"}} ... This generates the following issues: sql > start loading method 'library' lua error > lua error on line 153 in file /home/gverhaag/Stock/ProductSheet/productsheet_KG594.tex: /usr/share/texmf/tex/context/base/mkiv/l-sandbox.lua:180: module 'luasql.mysql' not found: no field package.preload['luasql.mysql'] no file '/usr/local/share/lua/5.2/luasql/mysql.lua' no file '/usr/local/share/lua/5.2/luasql/mysql/init.lua' no file '/usr/local/lib/lua/5.2/luasql/mysql.lua' no file '/usr/local/lib/lua/5.2/luasql/mysql/init.lua' no file './luasql/mysql.lua' no file '/usr/local/lib/lua/5.2/luasql/mysql.so' no file '/usr/local/lib/lua/5.2/loadall.so' no file './luasql/mysql.so' no file '/usr/local/lib/lua/5.2/luasql.so' no file '/usr/local/lib/lua/5.2/loadall.so' no file './luasql.so' stack traceback: [C]: in function 'requiem' /usr/share/texmf/tex/context/base/mkiv/l-sandbox.lua:180: in function </usr/share/texmf/tex/context/base/mkiv/l-sandbox.lua:165> (...tail calls...) ...are/texmf/tex/context/base/mkiv/util-sql-imp-library.lua:74: in main chunk [C]: in function 'requiem' /usr/share/texmf/tex/context/base/mkiv/l-sandbox.lua:180: in function </usr/share/texmf/tex/context/base/mkiv/l-sandbox.lua:165> (...tail calls...) /usr/share/texmf/tex/context/base/mkiv/util-sql.lua:114: in function '__index' /usr/share/texmf/tex/context/base/mkiv/util-sql.lua:288: in function 'execute' [ctxlua]:21: in function 'sql' [ctxlua]:5: in function 'sqldatabase' [ctxlua]:1: in main chunk Must be something basic, I guess!

Dear list, I have the following sample: \setupreferencestructureprefix [default] [prefixsegments=*:*] \starttext \section{One Section} \subsection[sec0]{Subsection} As told in \in[sec0] and \in[sec1]… \section{Another Section} \subsection[sec1]{Subsection} … \stoptext The output reads: As told in 1.1 and 2.1… I would like to be able to supress the section number in the reference, if the current section is the same as the referenced one. I mean, I would like that the output reads: As told in 1 and 2.1… Which would be the way to do it automatically? BTW, in my real--world document, I need to remove part and chapter numbers from the reference when in the same part and chapter (when compiling XML sources).

new upload
by Hans Hagen 04 Jun '21

04 Jun '21

Hi, I uploaded a new version of lmtx: a next step in this matrix and such graphic part ... (also bTABLE done). The matrix bit has a high level MP interface, also because it's a nice example of implementing one (not much code needed actually). Support in bTABLE .. eTABLE is kind of interesting as it separates the ornamental part from the text part. The sxample only shows some simple stuff. I'll probably also add this to the other table mechanisms. (Not hard but I don't want to impact performance when it's not used.) The \startoverlayMPgraphic{mp:whatever-6} is new and automatically defines the overlay so that saves some code. \startMPoverlaydata is just a collector that can be flushed in-line (which wilkl also reset it). All this is probably mostly useful in an educational setting. We'll see.

metafun transformation error
by Ajith R 04 Jun '21

04 Jun '21

Hi all, I am new to context and need help in solving an error. I am trying to print some numbers in a grid onto a transparent sheet as mirror images so that the numbers are correctly displayed when I view it from the non printed side. The numbers have a particular sequence which cannot be obtained from calculations. So, they are stored in an array of strings : l[0][0] := "38"; ... I place them at the centre of the grid squares using the code below: for i= 0 upto (row - 1): for j= 0 upto (col - 1): middle := 0.5[((( i * unit) + lm), ((j * unit) + bm)), ((((i+1) * unit) + lm), (((j +1) * unit) + bm))]; p := thelabel(l[j][i], middle); draw p; % q := p reflectedabout (0.5[urcorner p, ulcorner p], 0.5[lrcorner p, llcorner p]); % draw q; endfor endfor This works as expected. But, when I try to reflect the label by means of the commented code, I get an error : tex error > mp error on line 643 in file /home/ajith/Desktop/PlayGround/numgrid.tex: >> (xpart T_,ypart T_,-0.00581xpart T_+0.00497ypart T_+0.15294,-0.00497xpart T_ -0.00581ypart T_+0.98824,-0.00497xpart T_-0.00581ypart T_+0.98825,0.00581xpart T_-0.00497ypart T_-0.15294) !

new upload
by Hans Hagen 01 Jun '21

01 Jun '21

Hi, I uploaded a new lmtx version. This time a new mechanism. ----------------------------- From an upcoming details chapter: ----------------------------- The mechanism described here is still experimental. Although it could be implemented in \MKIV\ it is only available in \LMTX. Already early in \MKII\ we had a positioning mechanism available. At that time we had \DVI\ output and specials were used to track positions. A script calculated the positions that were then fed back into the second run. Later Taco wrote \DVIPOS\ which sped up the analysis between runs. When \PDFTEX\ showed, an equivalent positioning mechanism was added there. In \MKIV\ positioning support was optimized a bit as part of the upgrading process but the principles remained the same. The interface to positioning comes with a lot of commands and many of them relate to what we want to do with \METAFUN. The alternative interface discussed here is a bit simpler and has (at least now) less commands and, combined with local name spaces, can be easier to use in more local situations. It's also integrated in the frequently used \type {\framed} commands and has basic support at the \METAFUN\ end. The performance is comparable to the regular positioning mechanisms but especially at the \METAPOST\ end has less overhead. ----------------------------- Here are some examples: ----------------------------- \framed [synchronize=yes,align=normal] {% test test test 1 \sync{one}{1}test test 2 \crlf test test 1 \sync{one}{1}test test test 2 \crlf test 1 \sync{one}{1}test 2 \crlf test test test test 1 \sync{one}{1}test test 2 } \framed [synchronize=yes,align=normal] {% one one \sync{a}{1}two \sync{a}{2}three \crlf one one \sync{a}{1}two two \sync{a}{2}three \crlf one \sync{a}{1}two \sync{a}{2}three \crlf one one one \sync{a}{1}two \sync{a}{2}three } \framed [synchronize=yes,align=normal] {% \syncanchor{one}{1}{1}A \syncanchor{one}{2}{1}BBB \syncanchor{one}{3}{1}C \crlf \syncanchor{one}{1}{2}AA \syncanchor{one}{3}{2}C \crlf \syncanchor{one}{1}{3}AAA \syncanchor{one}{2}{3}BB \syncanchor{one}{3}{3}C } \framed [synchronize=yes,align=normal] {% \alignanchor{one}{1}{1}{l}A \alignanchor{one}{1}{2}{m}AA \alignanchor{one}{1}{3}{r}AAA \syncanchor {one}{1}{4}\crlf \alignanchor{one}{2}{1}{right}B \alignanchor{one}{2}{2}{middle}BB \alignanchor{one}{2}{3}{left}BBB \syncanchor {one}{2}{4} } \startuseMPgraphic{whatever-1} fill OverlayBox withcolor "lightgray" ; drawdot anchorxy("one", 0, 1) withpen pencircle scaled 1mm withcolor "red" ; drawdot anchorxy("one", 0, 2) withpen pencircle scaled 1mm withcolor "red" ; drawdot anchorxy("two", 0, 1) withpen pencircle scaled 1mm withcolor "red" ; drawdot anchorxy("two", 0, 2) withpen pencircle scaled 1mm withcolor "red" ; drawdot anchorxy("three", 0, 1) withpen pencircle scaled 1mm withcolor "red" ; setbounds currentpicture to OverlayBox ; \stopuseMPgraphic \startuseMPgraphic{whatever-2} pair a ; a := anchorxy("one", 0, 1) ; pair b ; b := anchorxy("one", 0, 2) ; drawarrow anchorxy("one", 0, 1) { right } .. anchorxy("one", 0, 2) withcolor "blue" withtransparency (1,.75) ; drawarrow anchorxy("two", 0, 1) { down } .. anchorxy("two", 0, 2) withcolor "blue" withtransparency (1,.75) ; drawarrow anchorxy("two", 0, 1) { dir 30 } .. anchorxy("three", 0, 1) withcolor "blue" withtransparency (1,.75) ; setbounds currentpicture to OverlayBox ; \stopuseMPgraphic \defineoverlay[whatever-1][\useMPgraphic{whatever-1}] \defineoverlay[whatever-2][\useMPgraphic{whatever-2}] \framed [synchronize=yes, align=normal, offset=10pt, frame=off, background={whatever-1,foreground,whatever-2}] {% \markanchor{two}{0}{1}{\red\bf foo}% \markanchor{one}{0}{1} bar rab oof\crlf foo bar rab oof\crlf oof rab bar foo\crlf oof rab \markanchor{two}{0}{2}{\red\bf bar}% \markanchor{one}{0}{2} foo% \markanchor{three}{0}{1}% } \framed [synchronize=yes, align=normal, offset=10pt, frame=off, background={whatever-1,foreground,whatever-2}] {% one one one \syncanchor{a}{1}{1}two two two \syncanchor{a}{2}{1}three three\par one \syncanchor{a}{1}{2}two \syncanchor{a}{2}{2}three\par one \syncanchor{a}{1}{3}two \syncanchor{a}{2}{3}three\par \blank \markanchor{two}{0}{1}{\red\bf foo}% \markanchor{one}{0}{1} bar rab oof\crlf foo bar rab oof\crlf oof rab bar foo\crlf oof rab \markanchor{two}{0}{2}{\red\bf bar}% \markanchor{one}{0}{2} foo% \markanchor{three}{0}{1}% \blank one one \syncanchor{a}{1}{4}two two \syncanchor{a}{2}{4}three\par one one \syncanchor{a}{1}{5}two two \syncanchor{a}{2}{5}three three% \markanchor{three}{0}{1}% } \framed[synchronize=yes,align=normal]{% one one \sync{a}{1}two \sync{a}{2}three\par one one \sync{a}{1}two two \sync{a}{2}three\par \blank tst tst \sync{b}{1}tst \sync{b}{2}tst\par tst \sync{b}{1}tst tst \sync{b}{2}tst\par \blank one \sync{a}{1}two \sync{a}{2}three } \page \startpacked $a = b + c $\par $b = c + d $\par $c = e + f $\par \stoppacked \startpacked \startsynchronizing $a \syncanchor{one}{1}{1}= b \syncanchor{one}{2}{1}+ c$\par $b \syncanchor{one}{1}{2}= c \syncanchor{one}{2}{2}+ d$\par $c \syncanchor{one}{1}{3}= e \syncanchor{one}{2}{3}+ f$\par \stopsynchronizing \stoppacked \startpacked \startsynchronizing $a \sync{one}{1}= b \sync{one}{2}+ c$\par $b \sync{one}{1}= c \sync{one}{2}+ d$\par $c \sync{one}{1}= e \sync{one}{2}+ f$\par \stopsynchronizing \stoppacked \startpacked \startsynchronizing $a \mathsync{1}= b \mathsync{2}+ c$\par $b \mathsync{1}= c \mathsync{2}+ d$\par $ \mordsync{1}= e \mathsync{2}+ f$\par \stopsynchronizing \stoppacked ----------------------------- remark ----------------------------- So, it's a varaant on the positioning mechanism. It also works in framed when the synchronization option is enabled. Don't enable that when not used (as there is some overhead involved). I have no clue how useful it is but users always find a way to use mechanisms. One can do really freaky things with it. Who knows what gets added over time. Also, it doesn't replace the existing positioning mechanism which served us well for decades; it's just a lightweight variant with different pros and cons.

Understanding penalties for orphans and widows
by denis.maier＠ub.unibe.ch 01 Jun '21

Hi, I've read in the wiki (https://wiki.contextgarden.net/Widows_and_orphans_control) that this setting can be used to keep at least two lines together: \startsetups[grid][mypenalties] \setdefaultpenalties \setpenalties\widowpenalties{2}{10000} \setpenalties\clubpenalties {2}{10000} \stopsetups After experimenting with the first argument (see below) it looks to me as if the wording on the wiki should be changed a bit, from <Example how to keep at least 2 lines together> to <Example how to keep at least 2 full lines together> (penalties1 gives me one full line and a second line that is almost full ; penalties2 results in two full lines with a third line that is almost full.). Is my interpretation correct?

new page before xtable with repeated headers
by Werner Hennrich 31 May '21

31 May '21

Hello everyone, I'm having an xtable spanning several pages and need to have its headers repeated. For this I've set "split=repeat", but unfortunately this causes the table to start with a new new page leaving the rest of the preceding page empty. Having "split=yes" makes the tabe continue on the previous page as a need it to, but then the header isn't repeated any longer. I realize that there has been a very similar question already in https://www.mail-archive.com/ntg-context@ntg.nl/msg93775.html, but my problem happens isolated in a very clean situation w/o any header, floats or the like - and I don't see yet how I can get this working in my situation. Any help is highly appreciated, here is a MWE of my problem: \definextable[mytable] \setupxtable[mytable] [ option=max, split=repeat, %split=yes, header=repeat, width=\textwidth ] \definextable[mytable:header] \setupxtable[mytable:header] [ foregroundstyle=\bf, foregroundcolor=darkred, ] % ================================================== \startdocument \dorecurse{2} { \input tufte \vskip7mm } \startxtable[mytable] \startxtablehead \startxrow[mytable:header] \startxcell Some Header \stopxcell \startxcell More Header \stopxcell \stopxrow \stopxtablehead \startxtablebody \dorecurse{10} { \startxrow \startxcell {\bf (\recurselevel) some tale:} \startitemize \item a quick \item brown fox \item jumps over \item the lazy dog \stopitemize \stopxcell \startxcell {\bf and a fact:} \startitemize \item the vodka \item is good \item but the meat \item is rotten \stopitemize \stopxcell \stopxrow } \stopxtablebody \stopxtable \stopdocument Thank you very much i.a., Werner

Hello colleagues, I’m writing a physics textbook with lots of figures, some quite complex. I’ve been using TikZ, but I’m experimenting with MetaPost. Consulting the ConTeXt wiki, I found that \startstaticMPfigure and friends are designed exactly for this sort of use. However, I’m not seeing the documented behavior. In particular, I’m not seeing .pdf and .mp.md5 files being produced. Perhaps I don’t know where to look. I thought they would be in the same directory as the document. The example from the wiki is this: \startstaticMPfigure{center} draw fullcircle scaled 2cm ; dotlabel.bot(textext("(0,0)"),origin) ; \stopstaticMPfigure \startstaticMPfigure{radius} draw fullcircle scaled 2cm ; drawarrow (0,0)--(1cm,0) ; label.bot(textext("$r$"),(5mm,0)) ; \stopstaticMPfigure \starttext Circle centered \usestaticMPfigure[center][width=1cm] at origin with radius \usestaticMPfigure[radius][width=1cm] $r=1\,\text{cm}$. \stoptext I would expect this to produce files center.pdf, radius.pdf, center.mp.md5, radius.md.mp5, and perhaps other logs, etc. I don’t see them anywhere. I’m running on MacOS with a current LMTX from TeXShop with the script: #!/bin/bash export PATH=/Users/Gavin/context-osx-64/tex/texmf-osx-64/bin:$PATH ~/context-osx-64/tex/texmf-osx-64/bin/mtxrun --autogenerate --script context --directives="system.showerror" --autopdf "$1” I’ve also tried MkIV and the TeXLive 2021 versions with the same results. I don’t actually need the separate pdf, but I do want the diagrams to be redrawn only when something has changed. Without a .mp.md5, I’m not sure what to expect. If the behavior has changed, I can update the wiki. I’m also curious about why \staticMPfigure is not mentioned in the MetaFun manual. Thanks Gavin

How to write readable source files?
by Jan U. Hasecke 30 May '21

30 May '21

Hi all, how do you format your ConTeXt source files? I recently discovered prettier which reformats source files for different markup and programming languages such as html, markdown, json etc. There are some other tools around but I don't find anything for ConTeXt. Do you know of any prettifying tool? Is there a best practice for ConTeXt source files, at all? Ciao! Jan Ulrich Hasecke

Synctex broken in LMTX ?
by Otared Kavian 29 May '21

29 May '21

Hi Hans, I have been noticing for some time that \setupsynctex does not work properly, at least in TeXShop on MacOS. A « filename.synctex » file is created but on most occasions it does not contain many lines, and one cannot go from the PDF file to the right location in the source file. Has something changed in the way synctex used to work ? Below I am sending you a test file with its PDF and .synctex files, for you to see for yourself. Sorry for the disturbance… Best regards: Otared

ctxlua percentage format escape
by Adam Reviczky 29 May '21

29 May '21

Hi, I was trying to use a quick calculation like the new mathfun in lmtx for an older mkiv document. MWE from the wiki: https://wiki.contextgarden.net/Programming_in_LuaTeX#Examples \starttext $\pi = \ctxlua{context("\%.6f", math.pi)}$ \stoptext But that gives an error (actually for both lmtx and mkiv): token call, syntax: [ctxlua]:1: invalid escape sequence near '"\%' Whereas \starttext $\pi = \startluacode context("%.6f", math.pi) \stopluacode$ \stoptext Works fine as expected. Is there a way to escape the percentage sign in ctxlua as a format value? Adam

Fwd: --luatex option failing
by jbf 29 May '21

Pablo, thanks for the assistance you gave me... it made me look at the cache inside the lmtx folders and I could see that the entire luatex folder was missing. I did try your --erase and --generate moves, but that did nothing to resolve things, so I installed the latest 2021.05.27 14:15 and the problem is resolved.

BibTeX inproceedings entries not rendered correctly in APA style
by Nicola 29 May '21

29 May '21

I don't know if this is restricted to inproceedings entries, but consider the following test.bib: @inproceedings{Foo:1983, author = {Foo, Bar}, booktitle = {Booktitle}, pages = {34--39}, title = {Title of the paper}, year = {1983} } When this is typeset: \usebtxdataset[test.bib] \usebtxdefinitions[apa] \starttext \cite[Foo:1983] \placelistofpublications \stoptext the result is: (Foo, 1983) Foo, B. (1983). Title of the paper. In Title of the paper., Booktitle. Author. I would expect: (Foo, 1983) Foo, B. (1983). Title of the paper. In Booktitle, p. 34–39. or something similar. I can reproduce it with ConTeXt from TeX Live 2021 and the current LMTX. Is it a bug? Nicola

LMTX and my custom typescripts
by Michael Guravage 28 May '21

28 May '21

Yesterday I installed a new LMTX instance *ex nihilo*. Unfortunately, the new instance will not load my typescripts. My several commercial fonts and the typescripts I wrote for them reside in the texmf-project tree, along with a style file that loads them. I load the style file in my source files with the \environment command. The files in texmf-project are properly indexed. I know this, because the style file's name appears in the log, because I can list the fonts with mtxrun --script fonts --list --files --all --pattern=Dolly*, and because he style file evokes \showframe and \showgrid; the result of which I see in the typeset results. Regardless of whether a typescript files, e.g. type-DollyPro.tex, is in the texmf-tree or in the same directory as the ConTeXt source file, evoking \usetypescriptfile[type-DollyPro] fails. The log says: fonts > typescripts > unknown library 'DollyPro' fonts > typescripts > unknown library 'DollyPro' However, including the typescripts in the ConTeXt source file succeeds; which would seem to imply that my typescript definitions are correct. Using an old instance: LMTX LuaTeX 2.03 20191227 + ConTeXt MkIV 2019.12.27 19:26, loading the typescript via the style file works as expected. I regret that my mwe remains academic, since you need the Dolly font to run it. Any encouragement in how to resolve this would be much appreciated. Cheers, Michael

--luatex option failing
by jbf 28 May '21

28 May '21

Hi list, Not at all sure why this is happening. In my most recent install of lmtx (which works fine as lmtx) on Linux, I wanted to choose the --luatex option just to make a comparison between the mkiv output and lmtx. The redirection part seems to work (... --script mtx-context --luatex myfile.tex --redirected), but no 'resolvers' follow. Instead I get mtxrun | unknown script 'mtx-context.lua' or 'mtx-mtx-context.lua'. I have tried both luatextools --generate and mtxrun --generate, but neither of these fix the problem. Would someone know why this is not working? Or even better, how to fix it? I installed lmtx on another machine and have no problems using the --luatex option there, so the matter is not urgent for me, just puzzling! I do have a separate mkiv installation as well, but my understanding is that they would not conflict. LMTX contains everything that is needed. Julian

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

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.

Stack size for arguments too small in LMTX

Dear list, For some reason pgfplots has a \pgfkeys invocation where the argument has more than 4000 lines. This crashes LuaMetaTeX with the message tex error > tex error on line 4045 in file pgfplots.code.tex: TeX capacity exceeded, sorry [token memory size=1000000] It doesn't seem to be an issue with LuaTeX, so my guess is that token memory size is larger in LuaTeX. Could you please increase the stack size to make this edge case compile again?

This is what I have come up so far: \define[1]\Transition{-\!\![#1]\!\!\rightarrow} \starttext \m{L\Transition{A}R} \stoptext This should render as -[ ]->, ideally with no space between the dash or the arrow and the brackets, i.e., -[ should appear like a single glyph; ditto for ]-->. With the definition above, however, the space is variable, and in some circumstances the gliphs overlap. How can I improve the above definition? Nicola

Special layouts don't recognise placeinitial
by Eduardo Bohoyo 24 May '21

24 May '21

My question will be very simple: Is there a trick to make \placeinitial command work within makeup pages? One of my pages inside the /frontmater/ is a quote page within an special layout. Before using LMTX, when I could use the Lettrine module, that quote started with a capital letter. But now that I use \placeinitial, the first letter no longer changes: it remains a simple initial capital letter. On the other hand, when I use \placeinitial for each first paragraph in the chapters of my book, the result is as expected. That is, the command works fine as long as it stays within the general layout. This is the code I'm referring to: \startmakeup[standard][doublesided=yes] \setuplayout[backspace=176pt,width=194pt] \setupinterlinespace[line=22pt] \style[tfa] \startalignment[hanging,flushleft,nothyphenated] \placeinitial Ahora, vosotros que amáis, dejadme que os formule una pregunta: ¿quién sufre más por ello, Arcite o Palamón? ¿El que ve a su dama diariamente, pero está encerrado para siempre, o el que es libre de ir donde le plazca, pero no verá nunca más a su dama? Aquellos de vosotros que podáis, elegid entre las dos situaciones a voluntad; yo, por mi parte, continuaré como he empezado. \stopalignment \startalignment[hanging,flushright,nothyphenated] \blank[0.8cm,force]{\tfa\sc Geofrey Chaucer,\hspace[big]} \blank[0.1cm,force]{\tfa\em The Canterbury Tales \hspace[big]} \stopalignment \stopmakeup Eduardo Bohoyo

LMTX install
by jbf 24 May '21

24 May '21

Someone will quickly clarify what I am doing wrong here. Have used mkiv until now but decided to download and install LMTX in /home/me/bin/context. I then ran export PATH=/home/me/bin/context/tex/texmf-linux-64/bin:$PATH as the install script indicated at the end. When running mk iv, I always first ran a setup line (in my case it was . /home/me/Documents/Freedom/Context/tex/setuptex). Do I need to run a setup also for LMTX installed as above? And what one, because there is no 'setuptex' as far as I can see. If I just run context myfile.tex I get the mtxrun | unknown script 'context.lua' or 'mtx-context.lua' message. Does this mean my 'path' command didn't work (and why not? It should have) or do I still need to run a setup before I try to compile? Julian

Unwanted upright math in MkIV
by Gavin 23 May '21

23 May '21

Hello, I’m using ConTeXt with MacOS. The current version of MkIV produces upright math rather than italic. MWE: \starttext \m{f = \beta} \stoptext The above example produces italic math TeXLive 2021 ConTeXt and in the current, LMTX. Looks like a bug to me, but maybe I am doing something wrong. I am running ConTeXt from TexShop using this engine: #!/bin/zsh export PATH=/Users/Gavin/context-osx-64/tex/texmf-osx-64/bin:$PATH ~/context-osx-64/tex/texmf-osx-64/bin/context --luatex --autopdf "$1” Thanks!

LMTX install

Hi Julian, afaik with lmtx a setup is not necessary. With mk iv it established the tex tree. With lmtx the tree is somehow self-contained.

Re: [NTG-context] mathfun (Hans Hagen)

Dear Hans, Thank you for your new module for math. If possible, I prefer to use $ \sqrt(x) = \compute\sqrt[.3N] {2} $ $ \pi = \mathexpr[.40N]{pi} $ It is more direct to use and good to write a text in which we need some math calculation. It is another good news for me. I hope it covers at least all the functions in metafun and in lua. Best regards, Dalyoung

I seem to be stuck at ver. 209.08 (context ver. 2021.04.29).

by Marcel Fabian Krüger 16 May '21

16 May '21

Hi, recently we got an interesting bug report in luaotfload (the original report is at https://github.com/latex3/luaotfload/issues/184) which relates to the ConTeXt fontloader. Take the following ConTeXt example: \starttext \definefontfeature [default:bold] [default] [axis={weight=500}] \definedfont[file:NotoSansCJKsc-VF.otf*default:bold @ 10pt] U+5E2E 帮 \stoptext The font is available at https://github.com/googlefonts/noto-cjk/raw/main/Sans/Variable/OTF/NotoSans…. This compiles correctly, but the CJK glyph do not appear since it's Type2 CharString is invalid. The CFF2 CharStrings of this glyph invokes the rrcurveto operator with 63 arguments, which is allowed in CFF2 where the argument limit is 513, but not allowed in Type2 where the limit is at 48. It would be great if ConTeXt could check for this and insert additional rrcuveto operators when necessary to avoid this issue. Additionally we got a report that inkscape 1.0 seems to be incompatible with the way commmands are passed to it for SVG files. Hendrik Seliger suggested to set f_convert (defined in font-ocl.lua, otfsvg.topdf, line 435) to `formatters["file-open:%s; export-%s:%s; export-do\n"]` when a new inkscape version is detected. (See https://github.com/latex3/luaotfload/issues/183) I wasn't able to reproduce the issue in ConTeXt yet. Best regards, Marcel

Expanding a figure into the second column
by Jeroen 16 May '21

16 May '21

I have the following MWE whereby the figure nicely fits the first column. If I now have a picture with more details and want to expand it partially into the second column, it will not work with width=1.5\textwidth , is there a simple way to achieve this? \starttext \startcolumns[n=2] \input{tufte} \placefigure [here] [] {my pic} {\externalfigure [cow] [width=.95\textwidth]} \dorecurse{3}{\input{tufte}} \stopcolumns \stoptext

Issue running ConTeXt from TeX Live 2019 on Alpine Linux 3.12
by Nicola 16 May '21

16 May '21

I'd like to run ConTeXt on Alpine Linux (ultimately, to run it on an iPad with the iSH app). I am currently testing it with Docker. This is what I have done: docker pull econcz/x86-alpine-glibc:ish-import docker run -it econcz/x86-alpine-glibc:ish-import /bin/sh cp /etc/apk/repositories /tmp/repositories cat /etc/os-release ALPINE_VERSION=3.12 # Set accordingly to previous command echo "http://nl.alpinelinux.org/alpine/v${ALPINE_VERSION}/main/" | tee /etc/apk/repositories echo "http://nl.alpinelinux.org/alpine/v${ALPINE_VERSION}/community/" | tee -a /etc/apk/repositories apk update This installs and configures repos for Alpine Linux 3.12. Then, I install TeX Live as follows: apk add texlive-full texlive-xetex texlive-luatex texlive-dev apk add ghostscript ghostscript-fonts ghostscript-dev apk add graphicsmagick graphicsmagick-dev Then, I run `mtxrun --generate`, which exits instantly with the output reported below. However, that is apparently not enough. I still get: $ context Hello-world.tex mtxrun | unknown script 'context.lua' or 'mtx-context.lua' $ context --version mtxrun | unknown script 'context.lua' or 'mtx-context.lua' $ mtxrun --version mtxrun | ConTeXt TDS Runner Tool 1.32 mtxrun | source path $ mtxrun --script context mtxrun | unknown script 'context.lua' or 'mtx-context.lua' $ luatools --generate mtxrun | unknown script 'base.lua' or 'mtx-base.lua' $ find / -name context.lua /usr/share/texmf-dist/scripts/context/lua/context.lua $ find / -name mtx-context.lua /usr/share/texmf-dist/scripts/context/lua/mtx-context.lua $ find / -name base.lua [Nothing found] $ find / -name mtx-base.lua /usr/share/texmf-dist/scripts/context/lua/mtx-base.lua Anyone running ConTeXt on Alpine?

randomize direction of arrow in metafun
by Thomas A. Schmitz 15 May '21

15 May '21

Hi all, for a slide template, I want to draw colored arrows in a randomized color (from a list of colors). This works (and the code is far too clever for me, I must have copied it somewhere): save mycolor ; color mycolor[] ; mycolor[1] := (0.2, 0.3, 0.4) ; mycolor[2] := (0.6, 0.6, 0.4) ; mycolor[3] := (0.5, 0.8, 0.5) ; so I can write drawarrow p withcolor mycolor[round(uniformdeviate(9))] ; But I also want the direction of the arrow to be random. My first idea was to define a variable that would expand either to "reverse" or the empty string right after drawarrow, but that's where I'm stuck. Anyone has an idea how to achieve this? (It's probably somewhere in the source, but I can't find it.) And is the method of defining the random color OK, or could this also be improved. Thanks, and all best Thomas

Hello everybody: My query is as follows: in LaTeX there is the package "pdfpages" (https://www.ctan.org/pkg/pdfpages) that allows pages from a PDF file to be included in a TeX document. Is there a similar procedure that works in ConTeXt? Thanks. M. González.

Adjusting parameters for a single page
by denis.maier＠ub.unibe.ch 11 May '21

11 May '21

Hi everyone, I know it is possible to make local changes by enclosing text in \start \stop pairs to make local changes. Then, there are also commands that only affect the next/current paragraph, such as \looseness. But is there a similar mechanism for page-layout changes? For example your penalty settings allow widows and orphans, but on one particular page you want to change the penalties. Or, you use \setupalign[height], but on one page you want to use \setupalign[bottom] instead. Is there a way to do this ? Best, Denis

Hi, With the latest luatex change from https://github.com/TeX-Live/luatex/commit/1566b63b338abbe38ed839fac9f2022eb… (and MKIV 2021-05-09 17:14:00) I get an input stack overflow: simpleslides > loading style Boxed system > command '\NormalHeight' is already defined system > command '\NormalWidth' is already defined system > command '\PictureFrameHeight' is already defined system > command '\PictureFrameWidth' is already defined close source > level 4, order 8, name '/usr/share/texmf/tex/context/third/simpleslides/s-simpleslides-Boxed.tex' close source > level 3, order 8, name '/usr/share/texmf/tex/context/third/simpleslides/t-simpleslides.mkiv' fonts > bodyfont '24.0414pt' is defined (can better be done global) metapost > initializing instance 'metafun:1' using format 'metafun' and method 'default' metapost > loading 'metafun' as '/usr/share/texmf/metapost/context/base/mpiv/metafun.mpiv' using method 'default' metapost > initializing number mode 'scaled' input stack overflow mtx-context | fatal error: return code: 256 MWE from the documentation: \usemodule[simpleslides][style=Boxed] \setupTitle[title={Title of the presentation},author={Name of authors},date={Date of presentation}] \starttext \placeTitle \SlideTitle{The first slide} Write whatever you want. \SlideTitle{The second slide} Continue writing. \stoptext Does that mean the simpleslides module has some recursion problems?

Tracking overfull/underfull vboxes, widows/orphans
by denis.maier＠ub.unibe.ch 10 May '21

10 May '21

Hi, some time ago Hans has added these trackers for overfull/underfull hboxes: I'm wondering if there is something similar for vertical boxes? I've found these trackers: builders.vspacing builders.vpacking builders.page_vspacing builders.collect_vspacing But I don't really understand what they do. (Yes, I've tried them.) Maybe someone can shed some light on this ? (RTFM is a perfectly fine answer, just need to know which manual...) Then, would it be possible to add a tracker for widows/orphans? (Or even for prevented widows/orphans ?) Denis

underscore hyphenation not working
by Pablo Rodriguez 10 May '21

10 May '21

Hans, some time ago, you provided me with the following code to hyphenate sha with underscore: \startluacode function document.addfunnyhyphen(tfmdata) local underscore = utf.byte("_") local char = tfmdata.characters[underscore] if not char then return end tfmdata.characters[0xFE000] = { width = 0, height = 0, depth = 0, commands = { { "right", -char.width }, { "down", char.depth }, { "slot", 1, underscore }, } } end utilities.sequencers.appendaction("aftercopyingcharacters", "after","document.addfunnyhyphen") local shared = { start = 1, length = 1, before = utf.char(0xFE000), after = nil, left = false, right = false, } local all = table.setmetatableindex({ }, function(t,k) return shared end) languages.hyphenators.traditional.installmethod("sha", function(dictionary,word,n) return all end) \stopluacode \definehyphenationfeatures [sha] [characters=all, alternative=sha, righthyphenchar="FE000] \sethyphenationfeatures[sha]% \setuphyphenation[method=traditional]% \starttext \hsize\zeropoint \tt abcde \stoptext I’m afraid that it isn’t working as expected with current latest from 2021.05.06 23:35. I wonder whether this might be caused by a bug or the code should be adapted to current latest. Many thanks for your help, Pablo -- http://www.ousia.tk

Update setpath to set the path
by Thangalin 10 May '21

10 May '21

Thoughts on updating the setpath.bat file to persist setting the path? Here's an updated version that sets the system environment variable while preserving the existing unexpanded PATH value: rem SOF echo off set OWNPATH=%~dp0 set PLATFORM=mswin if defined ProgramFiles(x86) set PLATFORM=win64 if "%PROCESSOR_ARCHITECTURE%"=="AMD64" set PLATFORM=win64 if exist "%OWNPATH%tex\texmf-mswin\bin\context.exe" set PLATFORM=mswin if exist "%OWNPATH%tex\texmf-win64\bin\context.exe" set PLATFORM=win64 echo %PATH% | findstr "texmf-%PLATFORM%" > nul rem Only update the PATH if not previously updated if ERRORLEVEL 1 ( set Key="HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" set "CurrPath=" for /F "USEBACKQ tokens=2*" %%A in (`reg query %%Key%% /v PATH`) do ( if not "%%~B" == "" ( rem Preserve the existing PATH echo %%B > currpath.txt rem Update the current session set PATH=%PATH%;%OWNPATH%tex\texmf-%PLATFORM%\bin rem Change the PATH environment variable setx PATH "%%B;%OWNPATH%tex\texmf-%PLATFORM%\bin" /M ) ) ) rem EOF Another possibility would be to define CONTEXT_HOME as an unexpanded value added to both the system environment variables and the PATH variable. For example (haven't tried it): setx CONTEXT_HOME "%OWNPATH%tex\texmf-%PLATFORM%\bin" setx PATH "%%B;%%CONTEXT_HOME%%" The advantage with this pattern is that subsequent updates need only check for CONTEXT_HOME and change its value without having to worry about PATH parsing, which can be hairy. Yet another option to consider is changing the value for only the existing user, rather than system-wide. Perhaps two different batch files? The reason for this change is because the Windows installation instructions (on the wiki) are incomplete: technically, the user must run setpath.bat for each new session. This implies that any third-party program that wants to make use of ConTeXt on Windows would have to communicate said fact to the user, or let the user set the full path to ConTeXt within the third-party program. Both of these can be avoided by persisting the PATH setting across sessions. Thank you! P.S. Pasted: https://pastebin.com/qpsqXZNB

weird word breaking in Win64

08 May '21

Dear list, the following sample breaks some words not right in Win64 (I cannot reproduce it in Linux): \enabledirectives[fonts.injections.method=advance] \setuppapersize[A6] \definefontfamily[mainface][rm] [TeX Gyre Pagella] \setupbodyfont[mainface] \starttext \input zapf \stoptext Copying text from latest Acrobat Reader DC, I get: Coming back to the use of typefaces in electronic publishing: many of the new typog raphers receive their knowledge and infor mation about the rules of typog raphy from books, from com puter mag azines or the instruction manuals which they get with the purchase of a PC or software. There is not so much basic instruction, as of now, as there was in the old days, showing the differences between good and bad typographic design. Many people are just fascinated by their PC's tricks, and think that a widely--praised program, called up on the screen, will make everything automatic from now on. Lines 3-5 contain word breaks that make searching impossible. This seems to be added by fonts.injections.method=advance. Could anyone on Windows confirm this issue?

upcoming versions of lmtx
by Hans Hagen 07 May '21

07 May '21

Hi, With luametatex becoming more mature, it's time to get rid of some old code. For instance, we have lmt files that assume 5.4, but regular lua files should work for luajittex (5.2) and luatex (5.3). Most noticable are the lack of bitwise operators and integer devision in luajittex, but there are more details. Till now, part of this problem is deals with by using functions that can actually be seen as macros that can are optimized when the format is made (kind of c-ish). It's not pretty, but works and probably no one ever noticed it. That mechanism will probably stay (for the fun of it) but the less it's used for creating the format the better. Another complication is that we use mtxrun for both running luatex and luametatex so there we need to be friendly to all three engines. But ... eventually luametatex will be the stub for also luatex and then mtxrun can become 5.4+ (the --luatex flag already works that way). An alternative is that we have mtxrun.lmt as well as mtxrun.lua but why bother. I also need to keep in mind that there are users of the font code that expect it to work with luajittex but that can be dealt with by splitting files. By splitting modules in lua and lmt variants we can tune for luametatex so that will happen anyway (less code, no engine specific sections, again a smaller format file, etc). All these adaptations have no functional consequences but of course there can be temporary hickups because of some oversight. At the engine level there is also some occasional cleanup, like replacing some left-over low level 5.2/5.3 lua api things by 5.4 but that's kind of ongoing (as lua progresses). In principle users should not notice such changes, just like probably no one noticed that we now use a different zip library (in the beginning some high speed variants were tested too but it's not that critical and I just don't want architecture dependencies that complicate a build and can influence stability). I still try to minimize the code base and dependencies, although I admit that sometimes stuff gets added (like the more efficient memory allocator). But my target max binary size of 3MB (less with link time optimization and related stripping) and fast compilation goals are still met.

very long hanging caption
by Jano Kula 07 May '21

07 May '21

Dear list, having images with very long captions I'd like captions to be wrapped around the figures. I would guess hang=yes parameter could do so, but not in my case. ---------------- text of | | the caption | | which is ---------------- much longer than the height of the image and should be wrapped around the image The second question is how to change the distance between image and the caption, distance parameter has no effect. MkIV, because footnotes in columns are needed (not in lmtx, yet). % macros=mkiv \setupcaption[ number=no, hang=yes, align={nothyphenated,flushleft}, distance=4mm, location=righthanging] \startbuffer[caption] \dorecurse{60}{very long caption } \stopbuffer \starttext \startplacefigure[title={\getbuffer[caption]}] \externalfigure[cow][height=40mm,width=80mm] \stopplacefigure \stoptext Thank you, Jano

Hi, I have just upgraded my LMTX install to OpenBSD 6.9. Unfortunately, my first context run aborted with this error message /usr/local/context/tex/texmf-openbsd6.9-amd64/bin/mtxrun[1]: syntax error: `newline' unexpected I tried mtxrun --generate and ended with alomst the same error message, as I could have expected /usr/local/context/tex/texmf-openbsd6.9-amd64/bin/mtxrun[1]: syntax error: `newline' unexpected I wiped the cache, then suppressed it, didn't change anything. Which informations might be helpful to solve this problem? Best regards, Damien Thiriet

Double-sided layer
by Huseyin Özoguz 06 May '21

06 May '21

Hello context-community, I have an image as a layer and want it to place on every page of a book with some offset. My minexample: \setlayer[mybg] [hoffset=2cm, voffset=0.2cm, doublesided=yes] {\framed[frame=off, width=2cm, height=1cm]{\externalfigure[bilder_bearbeitet_png/32.png][width=\textwidth]}} That works in principle, but I want the hoffset to be relative to the cutspace/backspace: different on right and left page, such that the layer is set equally on every page relative to the textbody. In the example above I use "doublesided=yes", but that has no effect. How to achieve proper double-sided behavior? Thank you. Huseyin

setupalign[line]/setupalign[height] break \testpage
by denis.maier＠ub.unibe.ch 06 May '21

06 May '21

Hi everyone, I've recently asked this question: https://www.mail-archive.com/ntg-context@ntg.nl/msg98293.html To reiterate: Is there any way to add a \vfill on a page immediately before a section heading? On the mailing list I then found a possible solution : \setuphead[section][aftersection=cmd] So, I thought \testpage or \checkpage here could be a solution. However, the vertical stretching algorithm seems to interfere with \testpage in some way as the example below tries to illustrate. Can anyone confirm this? Is this a bug or am I missing something? ======================== \setuppapersize[A5][A5] % Activate this and \testpage stops working %\setupalign[height] %\setuptolerance[vertical,stretch] %\setupinterlinespace[ % stretch=0.001, % shrink=0.001, % ] % \showframe \starttext \section{Section} \input knuth\par \input knuth\par \input knuth\par \input ward \input ward \testpage[20] % This stops working as soon as vertical stretching is active \input ward \section{Section} \input knuth\par \stoptext ======================== Best, Denis

environments in texmf-local?
by jbf 06 May '21

06 May '21

Hi list, A query: since we can place private (or any) modules in the texmf-local subdirectory and call them from anywhere, would it be a misuse to also place some environment setups there as well? It certainly makes it easy to call them from wherever, and saves having to reorganize my file and directory structure. Julian

new upload
by Hans Hagen 05 May '21

05 May '21

Hi, I uploaded a new lmtx version. The update mostly concerns part of the low level mp-tex interface, a side effect of updating some mechanisms (one of which MF currently is extending). Hopefully it won't break users code that uses low level mp-tex interface features but anyway, if needed, adapting is not hard and gives nicer code, as in: \startuseMPgraphic{foo1} fill fullcircle scaled \MPvar{size} withcolor \MPvar{color} ; \stopuseMPgraphic which now becomes: \startuseMPgraphic{foo2} fill fullcircle scaled mpvard("size") withcolor mpvars "color" ; \stopuseMPgraphic or even can be: \startuseMPgraphic{foo3} fill fullcircle scaled mpvar "size" withcolor mpvar "color" ; \stopuseMPgraphic where numerics, dimensions and strings are figured out automatically: \newdimen\mydimen \mydimen=1cm \useMPgraphic{foo1}{size=\mydimen,color=red} \useMPgraphic{foo2}{size=2\mydimen,color=green} \useMPgraphic{foo3}{size=3cm,color=blue} So it (still) works (even better) with registers and such. The fundamental difference is that \MPvar pushes the value of a variable from tex to mp (after some analysis) and that mpvar pulls the value from the mp end (with some help of the lua interface). New is that we have inheritance \setupMPvariables[foo3][size=1cm,color=yellow] \useMPgraphic{foo3} \setupMPvariables[foo1][foo3][size=2cm] \useMPgraphic{foo1} Another experiment, already active on my machine for a while, is this: \enabledirectives[metapost.text.fasttrack] which can be a bit more efficient wrt texts. Another pending change is getting rid of colorhack, which you can try with: \enableexperiments[disablecolorhack] Yet another (already mentioned) experiment users can (should) play with is \enableexperiments[simplegroups] And of course there are: \enableexperiments[fonts.compact] and the less fundamental (and more experimental too): \enabledirectives[fonts.injections.method=advance] At some point compact mode can become the default which then can trigger some low level code removal ... of course some sentimental issue because throwing away code that has been around for a long time, has evolved to be efficient and work well, can hurt but in the end nicer new code wins. Finally I want to remember overload protection: \enabledirectives[overloadmode=warning] or even \enabledirectives[overloadmode=error] just in case you want to check if your own macros clash or harm the system.
