Minimum METAPOST code produces problematic PDF
by Gerben Wierda 11 Jul '20

11 Jul '20

The following code: \startMPpage[instance=doublefun] draw (0,0)--(100,0) dashed withdots; \stopMPpage When run through LuaMetaTeX produces a PDF about which Acrobat complains: The dimensions of this page are out-of-range. Page content might be truncated. and Adobe InDesign cannot handle it at all (displays empty). The error message stays with \startMPpage[instance=doublefun] draw (0,0)--(100,0)—(100,2) dashed withdots; \stopMPpage but disappears with \startMPpage[instance=doublefun] draw (0,0)--(100,0)—(100,3) dashed withdots; \stopMPpage Additionally, on the Adobe forums I have been told: Also, the color space is device gray (not RGB or CMYK) which might be a more generic problem with LMTX output, I don’t know. It might also be an Adobe problem. Previw.app on macOS handles the result without problems.

error after Linux upgrade
by jbf 11 Jul '20

11 Jul '20

Hi, After upgrading from Linux Mint 19.3 to 20, when attempting to run the context mydoc.tex command, I get the following messages: jel@mycomputer:~/Documents/Context_docs$ context mydoc.tex resolvers | caches | path '/home/jel/.texlive2019/texmf-var' created mtxrun | unknown script 'context.lua' or 'mtx-context.lua' Obviously it needed to resolve a path issue and appears to have done so, but why did it choose .texlive2019/texmf-var? If I run 'locate context.lua' I get /home/jel/context/tex/texmf-context/scripts/context/lua/context.lua so how might I get Context to resolve to this latter? Julian

help with confusion re chapter number
by jbf 09 Jul '20

09 Jul '20

Hi, I wonder if someone could lead me out of my current confusion. In a test example with MWE as follows, I get exactly what I want: \setuplabeltext [en] [chapter=~] \define[2]\MyChapter {\framed[frame=off,width=broad,align=middle]{#1\blank[1cm]#2}} \setuphead [chapter] [command=\MyChapter] \chapter{Chapter title} which gives me a chapter number (without the word 'Chapter') and 1cm below it the chapter title, e.g.: 1 My chapter title But when I transfer this to the actual tex file I am working with, I lose the chapter number. Admittedly, there is more complication to my setup in the 'real' example, and maybe that's where I've gone wrong, but why am I losing the chapter number? \define[2]\MyChapter {\framed[frame=off,width=broad,align=middle,number=yes]{#1\blank[1cm]#2}} \setuphead [chapter][header=empty,alternative=middle,style=bold,numbercommand=\groupedcommand{}{\blank[2cm]},after={\blank[3cm]},command=\MyChapter] Julian

Space after Round bracket before Punctuation
by Richard Mahoney | Indica et Buddhica 09 Jul '20

09 Jul '20

I'm typesetting some proceedings which include a good number of round brackets followed by punctuation. This often occurs in the body of the text, but also in the hand coded bibliographies, e.g.: ) plus . , ; : The trouble is that excessive space is often introduced between the bracket and the punctuation. I can control the excessive space that sometimes occurs between ) and . by using )\periods[1], although this ruins the protrusion if it occurs at the end of a line. Does anyone know how I might be able to somehow "tie" ) to . , ; : so that the distance remains reasonable, and so that protrusion still works?

lmtx install fails to run
by Hans van der Meer 09 Jul '20

09 Jul '20

After doing just now the standard: sh install.sh context will not run. Why, because in the past it worked without a hitch. Now there is no format cont-en. Did all sorts of the ususal things like remove the current cache, context --make en, etc. I guess the error is in the missing file. An overfsight somewhere? Below the last part of the context --make en run. Mark the lang-mis.mkxl is not found line. met vriendelijke groet dr.

Great. That used to be 1 bp so now it's more. As it happens, we do have a check for this in context so we can adapt it ... but, as this 3 bp is kind of arbitrary and because 3 bp becomes a float and thereby ends up slightly less than the integer 3 we can best play safe and revert to the usual tex joke, so i now set the minumum to \luaexpr{math.pi}\onebasepoint which then gives: /MediaBox [ 0 0 3.141539539 3.141539539 ] because after all, any rediculous minimum will do and that way a user can still figure out that it's a value set by context.

re vertical space between Chapter number and title
by jbf 09 Jul '20

09 Jul '20

I have found my own answer to the question I asked earlier: \setuppapersize[A4] \setuplabeltext [en] [chapter=~] \define[2]\MyChapter {\framed[frame=off,width=broad,align=middle]{#1\blank[2cm]#2}} \setuphead [chapter] [command=\MyChapter] \chapter{Chapter title} It was simply a matter of working out where to put the \blank[2cm] (or whatever vertical space was required). It replaced {#1\\#2}} Julian

Vertical space between label and title
by Fabrice Couvreur 09 Jul '20

Hello, I want a vertical space between the label and the chapter title: is this the right way to proceed ? Thank you. Fabrice \setuplabeltext[chapter=Chapitre~] \unexpanded\def\Title#1#2{\framed[frame=off,width=fit,align=flushleft]{#1\blank#2}} \setuphead [chapter] [style=\bfc, command=\Title] \setupenumerations [before={\blank}, after={\blank}, alternative=serried, title=yes, prefix=yes, prefixsegments=chapter, way=bychapter, titlestyle=bold, width=broad] \defineenumeration [definition] [text=Définition, number=yes, headcommand=\groupedcommand{}{.}, style=italic] \starttext \startchapter [title=Nombres complexes : point de vue algébrique] \startdefinition \input zapf \stopdefinition \startdefinition \input zapf \stopdefinition \stopchapter \stoptext

more space between Chapter number and title
by jbf 09 Jul '20

09 Jul '20

Hi, I am using \setuppapersize[A4] \setuplabeltext [en] [chapter=~] \define[2]\MyChapter {\framed[frame=off,width=broad,align=middle]{#1\\#2}} \setuphead [chapter] [command=\MyChapter] \chapter{Chapter title} to successfully achieve the following result: 1 Chapter title But I would like to have more vertical space between the '1' and the 'Chapter title'. I thought if I added [before={\blank[2cm]}] somewhere in \framed (e.g. just before the {#1\\#2} argument, that I would achieve such a result, but that doesn't work. I also tried it as {\framed[frame=off,width=broad,align=middle,before={\blank[2cm]}]{#1\\#2}}, but that didn't work either. I am sure it is simple enough to achieve? Julian

About xstring and ConTeXt
by Jairo A. del Rio 08 Jul '20

08 Jul '20

Reading about macro bundles meant to be generic (format agnostic), some of them work in plain/LaTeX, but crash when loaded on ConTeXt. The following happens with xstring.tex tex error > tex error on line 372 in file xstring.tex: ! Illegal parameter number in definition of \xs_reserved_C <to be read again> 1 \xs_newlines ->\unexpanded {}\xs_def \xs_arg_i {##1 } \xs_newmacro_ ...name \xs_myarg }\edef \xs_reserved_C {\unexpanded \expandafter {\xs_newlines }\edef \noexpand \xs_call }\edef \xs_reserved_D {... l.372 \xs_newmacro\StrRemoveBraces{}{1}{1} {% <empty file> You meant to type ## instead of #, right? Or maybe a } was forgotten somewhere earlier, and things are all screwed up? I'm going to assume that you meant ##. I've tried changing the catcode regime, but with no effect. Don't misunderstand me. I'm aware of ConTeXt capabilities and string manipulation via Lua. My question is more like: "Why doesn't xstring.tex?" Sorry if my question is outside the scope of ConTeXt developers/maintainers. Thank you very much. Jairo :)
