How should I be compiling my for-printers file?
by Joel 24 Aug '24

24 Aug '24

I’m nearing the final stages of preparing a file for printing, which will be used to produce a textbook at a professional printer. The printer can accept PDF files, and I’ve been generating them using the context filename.tex command as part of my regular workflow. I’m wondering if this approach is producing the highest quality output for printing purposes. Is there anything additional I should consider, such as installing LuaTeX or running specific commands, or command-line switches, to ensure the best possible print quality? For context, when I installed ConTeXt standalone, it didn't seem to include LuaTeX by default, though after I installed, it asked me to run context --luatex commands which didn't function, so I worry my install isn't giving the best-possible output. --Joel

How do I get roman numerals in all numerable sections with no extra spacing after the period (would appreciate condensed code/simplification) (I read documentation but did not get any result)

\setuppapersize [letter] [letter] \setuplayout[ backspace=0.5in, topspace=0.5in, header=0in, % No headers footer=0in, % Space for the footer width=middle, height=middle, ] \definefontfeature [default] [default] [trep=yes] \definefontfamily [TimesNewRoman] [rm] [Times New Roman] \definetypeface [TimesNewRoman] [mm] [math] [stixtwo] \setupbodyfont [TimesNewRoman,12pt] \mainlanguage[en-us] \setupindenting[yes,0.5in] \setupheads[indentnext=yes] % To get indentation after section numbers, use this \setuphead[part][ page=no, placehead=yes, numbercommand=\groupedcommand{}{.} % Add period after numbers ] \setuphead[chapter][ page=no, numbercommand=\groupedcommand{}{.} % Add period after numbers ] \setuphead[section, subsection, subsubsection, subsubsubsection, subsubsubsubsection][ numbercommand=\groupedcommand{}{.} % Add period after numbers ] \setuphead[part, chapter, section, subsection, subsubsection, subsubsubsection, subsubsubsubsection, subject, subsubject, subsubsubject, subsubsubsubject, subsubsubsubsection][ before=, after=, style=sc, % Small caps style align=middle, % Center the section titles ] % it seems that when I make this into setupheads and delete the first square braket set it will not result in what I want \startsetups document:start \centerline{\documentvariable{title}} \centerline{\documentvariable{author}} \centerline{\documentvariable{date}} \blank[line] \stopsetups \startdocument[title=Title,author=Author,date=Date] \startpart[title=one] \stoppart \startalignment[middle] {\sc 1. one} % there is added space as shwon when trying to emulate what I want through regular text \stopalignment \startchapter[title=two] \stopchapter \startpart[title=three] \stoppart \startchapter[title=four] \stopchapter \startsubject[title=five] \stopsubject \stopdocument with this code I'm trying to get it so that part, chapter, and the 5 section levels will have roman numerals. I read the docs but didn't get the result I wanted for roman numerals and can't seem to figure out how to get rid of the tiny space that is after the period in the section stuff. Would love an answer for this.

Variable counting citations
by Niklas 20 Aug '24

20 Aug '24

Hi there, I want to show the bibliography at the end, only when there are actually citations in this document. My attempt was to create a custom defined command to combine a citation with incrementing a counter. Is this the right way, or is there any native variable that holds the number of citations? I also want to do the same with equations. Thank you very much and kind regards, Niklas von Hirschfeld

Probably a very simple question, but how do I get a page number to be centered, at the bottom and vertically in the middle whilst having my doc margins?
by Felix 19 Aug '24

19 Aug '24

I have the following code that I tried editing with no success https://pastebin.com/jT58Z8uY This has no footer or header but when I add code for a header that is AI generated it outputs a wrong result l, and I tried reading documentation too but didn't really find anything helpful What I want; everything that is included in the preamble that affects the sizing and alignment, but I want a bottom centered page number that is vertically aligned (it doesn't have to be perfect but I think context can oroabbly do that? I'm a complete novice, sorry). Would greatly appreciate if someone can format this into the doc. Thank you!

slanted fallback and compact fonts
by Pablo Rodriguez 19 Aug '24

19 Aug '24

Dear list, I have the following sample: %~ \enableexperiments[fonts.compact] \definefallbackfamily[mainface] [rm][TeX Gyre Pagella] [range={0x0061}, force=yes, it={style:tf, features:{slanted}}] \definefontfamily[mainface] [rm][TeX Gyre Pagella] %[it={style:tf, features:{slanted}}] \setupbodyfont[mainface] \startTEXpage[offset=1em] a \it a \stopTEXpage \stoptext Compact fonts in LuaMetaTeX prevent the slanted in the fallback font, but it causes no problem with the main defined font family. MkIV slants both the fallback and the main font families. I guess this might be some code preventing this from working. I’m using current latest (from 2024.08.16 16:30). Could anyone confirm the issue? Many thanks for your help, Pablo

Why are some external PDF figures leading to a stack overflow error?
by Joel 18 Aug '24

18 Aug '24

I am making a book that includes a series of maps which I created in LibreOffice Draw, but exported as a lossless PDF. After recently making some improvements to the map files, but not the ConTeXt documents, I was surprised my document wouldn't compile anymore...I couldn't find any code errors and even reverted to older code from the day before that compiled fine yesterday. It seemed the PDFs themselves were making the errors, but the errors were inconsistent.. I deleted my ConTeXt install and downloaded the latest version of standalone, it still won't compile, but the errors are completely different. After a few tests I came up with this minimal code which throws the error: \starttext \externalfigure[xmap1] \stoptext If I compile this, and xmap1.pdf is a PDF file in the same path, it outputs this error: lua error > lua error on line 4 in file ./test.tex: registered function call [1606]: ...ext/tex/texmf-context/tex/context/base/mkxl/lpdf-pde.lmt:175: stack overflow stack traceback: ...ext/tex/texmf-context/tex/context/base/mkxl/lpdf-pde.lmt:175: in function <...ext/tex/texmf-context/tex/context/base/mkxl/lpdf-pde.lmt:167> (...tail calls...) ...ext/tex/texmf-context/tex/context/base/mkxl/lpdf-pde.lmt:667: in for iterator 'for iterator' ...-context/tex/context/base/mkxl/lpdf-fix-imp-contents.lmt:96: in upvalue 'strip' ...-context/tex/context/base/mkxl/lpdf-fix-imp-contents.lmt:97: in upvalue 'strip' ...-context/tex/context/base/mkxl/lpdf-fix-imp-contents.lmt:97: in upvalue 'strip' ...-context/tex/context/base/mkxl/lpdf-fix-imp-contents.lmt:97: in upvalue 'strip' ...-context/tex/context/base/mkxl/lpdf-fix-imp-contents.lmt:97: in upvalue 'strip' ...-context/tex/context/base/mkxl/lpdf-fix-imp-contents.lmt:97: in upvalue 'strip' ...-context/tex/context/base/mkxl/lpdf-fix-imp-contents.lmt:97: in upvalue 'strip' ...-context/tex/context/base/mkxl/lpdf-fix-imp-contents.lmt:97: in upvalue 'strip' ...

Two column layout with footnotes
by Michael Loescher 18 Aug '24

18 Aug '24

Hello list, Is it possible to create a two-column journal layout with ConTeXt in which relatively large footnotes are always in the right column and, if the size of the footnotes exceeds a certain threshold, are distributed between the left and right columns? (comparable as shown in the attachment) As far as I understand it, there are different possibilities for column set (e.g. column set, pagecolumns), but which one would be best, if it is possible at all? Kind regards Michael

Bug Regarding IIalic Correction in ConTeXt LMTX
by Vladimir Grbić 18 Aug '24

18 Aug '24

Hello, I started using ConTeXt LMTX 2 days ago and after some initial testing I noticed an unexpected behavior regarding italic correction. In short, I cannot seem to produce italic correction like I could in plain TeX or even LaTeX. I've asked the question on TeX StackExchange and another user confirmed the suspicion in his answer. I would suggest you take a look at it because the formatting of the question and the answer is prettier than in this plain text email. Furthermore, a person who provided the answer already did some research. See the question here: https://tex.stackexchange.com/questions/724568/how-to-invoke-italic-correct… Here is what I observed: Compare the kerning produced in between 'r' and 'p' in the word "airport" when italic correction is applied in plain TeX (compiled with `pdftex`) and in ConTeXt LMTX (compiled with `luametatex`). Here are the minimal working examples. Plain TeX ``` airport (regular font) {\it air\/}port (italic correction applied) {\it air}port (no italic correction applied) \bye ``` ConTeXt LMTX ``` \starttext airport (regular font) {\it air\/}port (italic correction applied) {\it air}port (no italic correction applied) \stoptext ``` Please confirm if this, in fact, is the issue/bug or if I am not approaching this correctly. I am brand new to ConTeXt, so it could be me. Thank you in advance! Vladimir

how to set OSFONTDIR to find font under the path com_apple_MobileAsset_Font7 in macOS ?
by ai2472206007＠yeah.net 17 Aug '24

17 Aug '24

hi,lists In macOS, some fonts (e.g klee, stkaiti ,lihei) will be downloaded under the path --> /System/Library/AssetsV2/com_apple_MobileAsset_Font7/, and I set the system font environment like: --> export OSFONTDIR=/Library/Fonts/:/System/Library/Fonts:$HOME/Library/Fonts:/System/Library/AssetsV2/com_apple_MobileAsset_Font7. But why can't I retrieve the font in this path? I've rebuilt the index after setting up the environment. Thanks for the help. Muyik
