luatex on the garden
by Hans Hagen 31 Aug '18

31 Aug '18

Hi, We now have a new version of luatex on the garden. This is the anual context meeting release which is a prelude to next years 1.10 version for texlive. The version number is 1.08 (as 1.09 will be out in a few months and mostly concerns some fixes needed for arm). For the average user there are no real differences (luatex 1.10 will basically be functionality complete). Of course we use lua 5.3 (1.10 might actually use 5.4). You can expect (depending on usage) a bit better performance as i wrapped some (yet) unsupported stuff into fallback functions. Things to watch out for: context now uses a one-pass mp approach which so far worked ok (alan an i tested it in regular usage). This might boost performance in case where extensive mp embedding takes place. Poppler is gone and replaced by pplib by Pawel Jakowski written for us. Currently he and luigi are finetuning the c code for portability. Users should not notice this (but it removes a dependency). More on some of the consequences later. It also makes the binary smaller. The binary mode in mplib is not available in luatex. It has no real benefits (and is probably not used, not even by alan) apart from research. This removes a large dependency on foreign code (we try to minimlize that) and again makes the binary smaller. We might introduce 64 bit scaled at some point (luigi will look into that next year). There are some changes in terms of efficiency that kick in now. I only tested on my setup but it's probably ok. Don't expect drastic improvements wrr to average performsance from now on. For those on windows: i noticed a performance difference between the native and mingw binaries (with native being slower, mostly due to format saving and loading). A lot of work went into this release and we hope that it's worth it. I will rmove some older code paths in a few weeks (less code that way) so then beta's will assume the new binary is used.

about character expansion
by Pablo Rodriguez 30 Aug '18

30 Aug '18

Dear list, I would like to introduce character expansion to novice users. I know that ConTeXt adds values automatically. But I’m interested in showing extremely stretched and shrinked characters, as an example of character expansion done wrong. Sorry for not providing a minimal example, but I don’t have any idea about how to achieve that. Does anyone know how to do it? Many thanks for your help, Pablo -- http://www.ousia.tk

Table of contents setup
by Willi Egger 30 Aug '18

30 Aug '18

Hello, I am busy to typeset a book with Maguntia.ttf. I should prepare the TOC with leaders. However how can I get ConTeXT to use the same leader-size on all levels which need leaders? As in the given example the leaders are adapted to the size of the font. Secondly I would like to have the page numbers all in the same size, irrespective from the level. Thirdly, I would love to adapt the distance between the leader-dots to a bigger size. How to do that? Kind regards Willi

Emacs + latest beta
by Fabrice Couvreur 30 Aug '18

30 Aug '18

Hello, Sorry to insist, but could anyone help me understand the problem I'm having in using Emacs with standalone context ? The following file compiles perfectly from a terminal : /home/aragorn/texlive/2018/bin/x86_64-linux/context test.tex /home/aragorn/context/tex/texmf-linux-64/bin/context test.tex (latest beta) With Emacs, it compiles perfectly if you use the 2018 texlive context binary. If I want to use the latest beta context binary, I need to add this to my ~/.emacs file : (setenv "PATH" "/home/aragorn/context/tex/texmf-linux-64/bin/:$PATH" t) And there, I encounter a compilation problem : Running `ConTeXt Full' on `pouf' with ``context --purgeall --nonstop pouf.tex''resolvers | trees | analyzing 'home:texmf' mtx-context | run 1: luatex --fmt="/home/aragorn/context/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/formats/luatex/cont-en" --interaction="nonstopmode" --jobname="pouf" --lua="/home/aragorn/context/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/formats/luatex/cont-en.lui" --no-parse-first-line --c:currentrun=1 --c:fulljobname="./pouf.tex" --c:input="./pouf.tex" --c:kindofrun=1 --c:maxnofruns=9 --c:nonstopmode --c:purgeall "cont-yes.mkiv" This is LuaTeX, Version 1.08.0 (TeX Live 2018) system commands enabled. resolvers > trees > analyzing 'home:texmf' open source > level 1, order 1, name '/home/aragorn/context/tex/texmf-context/tex/context/base/mkiv/cont-yes.mkiv' job > passes > version mismatch: 1.3 <> 1.31 system > system > ConTeXt ver: 2018.08.20 17:47 MKIV beta fmt: 2018.8.20 int: english/english system > system > 'cont-new.mkiv' loaded open source > level 2, order 2, name '/home/aragorn/context/tex/texmf-context/tex/context/base/mkiv/cont-new.mkiv' system > beware: some patches loaded from cont-new.mkiv close source > level 2, order 2, name '/home/aragorn/context/tex/texmf-context/tex/context/base/mkiv/cont-new.mkiv' system > files > jobname 'pouf', input './pouf', result 'pouf' fonts > latin modern fonts are not preloaded languages > language 'en' is active open source > level 2, order 3, name '/home/aragorn/pouf.tex' fonts > preloading latin modern fonts (second stage) fonts > 'fallback modern-designsize rm 12pt' is loaded structure > sectioning > chapter @ level 2 : 0.1 -> First chapter metapost > initializing instance 'metafun:1' using format 'metafun' and method 'default' metapost > loading 'metafun' as '/home/aragorn/context/tex/texmf-context/metapost/context/base/mpiv/metafun.mpiv' using method 'default' metapost > initializing number mode 'scaled' lua error > lua error on line 10 in file /home/aragorn/pouf.tex: ...ext/tex/texmf-context/tex/context/base/mkiv/node-nut.lua:190: attempt to call a nil value (global 'getid') stack traceback: ...ext/tex/texmf-context/tex/context/base/mkiv/node-nut.lua:190: in upvalue 'getexpansion' ...ext/tex/texmf-context/tex/context/base/mkiv/font-mps.lua:343: in function <...ext/tex/texmf-context/tex/context/base/mkiv/font-mps.lua:338> ...ext/tex/texmf-context/tex/context/base/mkiv/font-mps.lua:437: in local 'boxtomp' ...ext/tex/texmf-context/tex/context/base/mkiv/mlib-pps.lua:1894: in function <...ext/tex/texmf-context/tex/context/base/mkiv/mlib-pps.lua:1891> (...tail calls...) 1 2 \startusableMPgraphic{NumberHead} 3 draw outlinetext.f 4 ("\bf\namedheadnumber{chapter}") 5 (withcolor "lightgray") 6 ysized 50pt ;

Question on enabling/disabling modes
by Mikael P. Sundqvist 30 Aug '18

30 Aug '18

Hi! I am writing notes for my teaching and would like to do the following with modes: * If the file is compiled with context file.tex then everything (i.e. the content in all modes) is typeset. * If the file is compiled with context --mode=test1 file.tex then only mode test1 is typeset. I do not see how to do this easily. The example I am working on looks like this: %%% file.tex \definemode[test1][keep] \definemode[test2][keep] \starttext \startmode[test1] We are in mode test1. \stopmode \startmode[test2] We are in mode test2. \stopmode \stoptext %%% This, however, naturally gives not output, since the modes test1 and test2 are not activated. If I compile with context --mode=test1 file.tex I get the content in mode test1, as I want. I have tried to change "keep" to "yes" in the setup of the modes, but then the material in both modes are typeset no matter what command flag I use. Do I miss something? /Mikael PS In reality I have about 25 lectures, so using this method there will be about 25 modes in total.
