Hanging hyphen in the left margin in Portuguese
by Marcus Vinicius Mesquita 18 Oct '16

18 Oct '16

Dear list, In Portuguese many times we have words with one or two explicit hyphens; for example: “tornar-nos-emos” (we shall become). When at the end of a line, it is mandatory to repeat the explicit hyphen both at the end and in the beginning of the next line. I managed to do this using: \definebreakpoints[portuguese] \definebreakpoint [portuguese] [-] [type=5,left=-,right=-,middle=-] \setbreakpoints[portuguese] If I use \setupalign[hz,hanging] I get the first hyphen hanging in the right margin. My question is: How do I manage to have the second hyphen in the beginning of the new line also hanging to the left in the left margin? TIA Marcus Vinicius

Systemwide installation does not work
by Roger Mason 18 Oct '16

18 Oct '16

Hello, System: FreeBSD 10.2-RELEASE-p18. I deleted my old context installation and followed the instructions here: http://wiki.contextgarden.net/ConTeXt_Standalone#Standalone for a 'System-wide installation' in /opt/context Here is what happens: sh ./first-setup.sh --modules=all receiving incremental file list bin/ bin/luatex bin/mtx-update.lua bin/mtxrun bin/texlua -> luatex sent 92 bytes received 11,386,172 bytes 843,426.96 bytes/sec total size is 11,383,119 speedup is 1.00 /opt/context/bin/texlua: ELF: not found /opt/context/bin/texlua: 0@x®¤@8: not found /opt/context/bin/texlua: @x®¤@8: not found /opt/context/bin/texlua: x®¤@8: not found /opt/context/bin/texlua: ¤@8: not found /opt/context/bin/texlua: @8: not found /opt/context/bin/texlua: @8: not found /opt/context/bin/texlua: @8: not found /opt/context/bin/texlua: @@@@0LLLLzMBzMBtt®t®9ØpY77´7´P$L$$Påtd¦ ¦¦ôôæÛ£ettRåtdtt®t®XëXë: not found /opt/context/bin/texlua: 5´h: not found /opt/context/bin/texlua: 1: Syntax error: Unterminated quoted string /opt/context/bin/texlua: 18: Syntax error: Error in command substitution When you want to use context, you need to initialize the tree by typing: . /opt/context/tex/setuptex in your shell or add "/opt/context/tex/texmf-freebsd-amd64/bin" to PATH variable if you want to set it permanently. This can usually be done in .bashrc, .bash_profile (or whatever file is used to initialize your shell). Something seems to be broken. Can someone help? Thanks, Roger

Becoming a TeX/ConTeXt poweruser
by Jamie Macbeth 17 Oct '16

17 Oct '16

Hello, I was fed up with LaTeX, and became a newbie user of ConTeXt, and I think it's great and I really agree with the philosophy. However, I also have to agree with some of what has been said about the lack of good documentation for those learning ConTeXt. I've built a couple of simple documents using ConTeXt, but I'm having trouble customizing to get some functionality that I used to get from LaTeX packages, and to customize things to fix issues that I had with LaTeX. I typeset technical papers and books with complex diagrams (e.g. xypic), charts and tables, tables embedded in tables, images inside tables, among other things. I'm hoping to become a poweruser of TeX through ConTeXt and LuaTeX. >From what I've read on this list so far, knowledgeable members of the community say that the key functionality to ConTeXt is in the "core". I would like to become a power user of TeX/LuaTex/ConTeXt by learning ConTeXt from the ground up and understanding the core at the source code level. I think this will make me skilled at rolling my own styles and fixing issues on my own as I encounter them. I'm an experienced software engineer with some knowledge of TeX (on the level of Knuth's "The TeXbook") and I'm happy to learn Lua. I want to actually read and understand the mkiv core source code and, just to start, understand how simple directives (for example \startitemize ... \stopitemize), are compiled from end to end and where their macro source code comes from (In this example I think it's in tex/texmf-context/tex/context/base/mkiv/typo-itm.mkiv but I'm not positive). I know that \startitemize ...\stopitemize is very customizable, but I would like to learn ConTeXt by learning how I could, for example, build the itemize environment myself from scratch. Can someone give me pointers on the best place to start? Then I can learn the code on my own (and not be a pest on this list :) ).

\definebodyfont not working for \typesetbuffer
by Pablo Rodriguez 16 Oct '16

16 Oct '16

Dear list, I have the following sample: \definebodyfont[17pt] \startbuffer[buffer:inside] \definefontfamily[mainface][rm][TeX Gyre Pagella] \setupbodyfont[mainface, 17pt] \starttext \input zapf \stoptext \stopbuffer \starttext \typesetbuffer[buffer:inside] \stoptext As suggested by Wolfgang, \definebodyfont should work. It worked then (https://mailman.ntg.nl/pipermail/ntg-context/2016/085260.html) but it doesn’t work with latest beta from 2016.10.14 17:19. Could you confirm whether it is a bug or I am missing something? Many thanks for your help, Pablo -- http://www.ousia.tk

Asciidoc --> ConTeXt for presentations
by Saša Janiška 16 Oct '16

16 Oct '16

Hello, I plan to adopt AsciiDoc(tor) as general markup for my writing (web content, blog posts, study notes etc.) and I’d prefer to use ConTeXt for my & wife’s presentations over something like reveal.js, so wonder if anyone has some experienec with the AsciiDoc --> ConTeXt (converted by Pandoc) toolchaincan? I use Emacs as my editor (currently on Debian Linux, but soon probably on FreeBSD/TrueOS)… Sincerely, Gour -- In the material world, one who is unaffected by whatever good or evil he may obtain, neither praising it nor despising it, is firmly fixed in perfect knowledge.

Dear list, I want to report a possible bug (I think), when one try to put a footnote into another footnote, here is MWE (from wiki): \starttext This\footnote{Or that\footnote{Or possibly even the other.}, if you prefer.} is a sentence with a footnote. \stoptext As you can see, the second footnote is not placed in the page. Thanks.

Issue with \blank halfline and title heads
by josephcanedo＠gmail.com 16 Oct '16

16 Oct '16

Dear list, I would like to have a chapter title consisting of 1 line, halfline spacing, another set of lines, and another halfline spacing (I use grid=both but same issue with grid=yes), but I fail to acheive this. I give a simple MWE that shows wanted effect (without heading) which works all fine, followed by sample chapter which shows that ‘E’ is above the grid base line (added \showgrid to make it visible). Do I need to put the title content in some box ? Thanks a lot for any hint, Best regards Joseph \showgrid\showstruts \setuplayout[grid=both] \definehead[Chapter][subsection] \setuphead[Chapter][number=no, align=center, style=\tf, before={\blank[none]}, after={\blank[none]}, grid=both] \starttext \startalignment[center] \strut E\blank[halfline]A\strut\blank[halfline] \stopalignment Paragraph text. \blank[line] \startChapter[title={\strut E\blank[halfline]A\strut\blank[halfline]}] Paragraph text. \stopChapter \stoptext

buffers inside startMPpage
by Jan Willem Flamma 14 Oct '16

14 Oct '16

Dear list members, I create all my MetaFun drawings in a separate environment file where each individual drawing sits inside a start/stopbuffer. This allows me to easily use those drawings in all my documents using \processMPbuffer[name]. Works just fine. However, I also wish to have all the drawing available in a pdf file (each drawing on a separate page). This allows me to split the pdf and use the drawing elsewhere (e.g. in a Powerpoint) or include page(s) from the pdf in another document. The below MWE represent my MetaFun drawings file. The idea is that by uncommenting the \enablemode[makepdf] I can create the pdf file with drawings. It seems however that startMPpage does not accept buffers (I also tried processbuffer and processMPbuffer). Is it possible to somehow make this work? Thanks and regards, Jan Willem Flamma %\enablemode[makepdf] \startbuffer[fig1] draw fullcircle scaled 2cm withcolor red ; \stopbuffer \startbuffer[fig2] draw unitsquare scaled 2cm withcolor red ; \stopbuffer \startmode[makepdf] \starttext \startMPpage \getbuffer[fig1] \stopMPpage \startMPpage \getbuffer[fig2] \stopMPpage \stoptext \stopmode

filter module: call function before calling the filter command?
by Henning Hraban Ramm 13 Oct '16

13 Oct '16

Ahoi! As you probably know ;), I’m using the filter module with LilyPond, setup see below. Now, I’d like to overwrite "texsettings.ly", containing the setting of ConTeXt’s text width, each time before I call LilyPond, to adapt its note line width to the current text width. That would automate the line width adaption to e.g. columns. In the module’s documentation under "Dealing with expansion" I found the example of creating the filter command in a macro. Can I use this to call a Lua function first and then LilyPond? Or is there a better way? ----- \usemodule[filter] \startbuffer[lilypond::settings] \include "../lilysettings.ly" % file must be in same folder as text, not in lilytemp \include "texsettings.ly" \stopbuffer \def\LILYTEMP{lilytemp} % name of folder for LilyPond/buffer files \def\ParseLilypondFile#1% #1 is the name of the output file {\ctxlua{thirddata.parselilypondfile("#1")}} \startluacode thirddata = thirddata or {} -- create temp folder if missing if not lfs.isdir("\LILYTEMP") then lfs.mkdir("\LILYTEMP") end -- write text width to include file io.savedata("\LILYTEMP/texsettings.ly", "\\paper { line-width = " .. string.gsub(number.topoints(tex.dimen.textwidth),"pt","\\pt") .. " } \n") function thirddata.parselilypondfile(name) -- include all systems (pages) -- name is like \LILYTEMP/mainfile-temp-lilypond-21.pdf logs.report("LILYPOND","name='" .. name .. "'") local scname = string.gsub(name, '%.pdf$', '-systems.count') local syco = tonumber(io.loaddata(scname)) or 0 for nr = 1, syco do logs.report("LILYPOND","including system no." .. nr) context("\\externalfigure[" .. string.gsub(name, '%.pdf$', '-' .. nr) .. "]") end end \stopluacode \defineexternalfilter[lilypond] [continue=yes, cache=yes, %purge=no, readcommand=\ParseLilypondFile, bufferbefore={lilypond::settings}, directory=\LILYTEMP/, output={\externalfilterbasefile.pdf}, filtercommand={lilypond -dbackend=eps -dinclude-eps-fonts -dno-gs-load-fonts -o"\LILYTEMP/\externalfilterbasefile" "\externalfilterinputfile"}] \starttext ----- Greetlings, Hraban --- http://www.fiee.net http://wiki.contextgarden.net https://www.cacert.org (I'm an assurer) GPG Key ID 1C9B22FD
