Question: Are there any ConTeXt aware scientific pulishers yet
by Christoph Hintermüller 19 Apr '20

19 Apr '20

Hi Jet a completely different question just out of curiosity? 1) Does anybody know of any scientific publisher or single journals which accept papers/book chapters typeset in ConTeXt yet 2) If there are any is any of them convinced enought about ConTeXt to recommend use of ConTeXt or even provide template? 3) What would be needed and what could help to make them aware? (difficult to properly formulate, if unclear dont bother) Best Xristoph -- Christoph Hintermueller Eisenhandstraße 33/23 4020 Linz Austria Tel.: +43 650 8827347 mail: christoph(a)out-world.com www: http://www.out-world.com

Introducing myself
by David van Diepen 19 Apr '20

19 Apr '20

Dear everybody, I don't have a particular question for the moment but I thought it would be nice to introduce myself as I have just joined the email list. My name is David van Diepen, 49 years old. I am a process engineer. I have two children. A few months ago my son had to prepare his thesis and that's when I thought latex would be applicable. Very many years ago I learned to work with latex during my education, so I thought that it wouldn't be too hard to help him out with that. At the end of the day it actually was hard work to get to grisps again but after 10 days we had prepared a very good-looking thesis and that's what counts. In the line of my work I regularly have to prepare technical documents. So I thought it's perhaps a good idea to start using latex for that too. My teamleader has given me some space to do that even though latex is completely unsupported at work, so I'm doing all that from home. The first document was recieved quite wel actually. As you'll probably understand my collegues have difficulty appreciating the value of a properly designed document. Everybody seems to agree to a similar and often poor appearance. I am the son of a graphic designer, so maybe that's why I do care what the documents I produce look like. For instance, I have a couple of nice books with examples of typefaces (letterproeven) lying about that I inherited, these are an inspiration too. Also I think a well designed document conveys the content better. So I'm glad that I am allowed start with this development even though the benefits are very abstract still. That's when I thought whether it would be a good idea to continue investing time in latex, or whether it would be better to go with the new developments, that being the luatex/context combination. So I thought I should at least give it a try. That try was actually harder than I expected. On hindsight I think it could have been easier if I had found the right channels to documentation sooner. There is a lot of information on context to be found but that includes a lot of information that's already superseded. So a couple of times it took me quite some time before I realized there was a newer and easier method. Anyway I'm well on my way now with my first technical ducument in context. The thing I like most about context is that the structure makes good sense. In latex there have been so many additions troughout the years that it has become quite messy really. In the longer run I think the greater array of possibilities is going to pay off for my purposes too. So I would like to thank you all for allowing me to use this great software. I expect that I may post questions in the future because I am planning to try more things. For now it's maybe a good idea if I put some contributions in the wiki. As a newby I have struggled at some points and maybe some howto's with that perspective can be helpful for other newcomers. For now, thanks again, yours faithfully, David

I've seen the following solution in Stack Exchange to add referenceable enumeration labels to a framed enumeration environment: https://tex.stackexchange.com/questions/438588/context-and-metafun-framed-e… It uses \wrappedcurrentconstruction. However, it only prints the counter label and the counter name. What if I need the text enclosed by braces in the frame header too? E. g. \starttheorem[thm1]{Residue theorem} so the framed title includes "Residue theorem" also. Thank you in advance.

lmtx vs mkiv
by Hans Hagen 18 Apr '20

18 Apr '20

Hi, One problem of mixed usage of mkiv (with luatex) and lmtx (with luametatex) is that in the later we use a different (initial) context runner. Basically all platforms are now handled the same (in mkiv there was a stub and no texlua, in unix something shebang with texlua because of argument passing limitations). However, the main context script can be told to use a specific engine: context --luatex foo.tex so in principle one can use both lmtx and mkiv with the same binary tree, given that luametatex and luatex are both present and that luametatex is in charge. For that reason the latest lmtx installer now (for the time being) also includes the luatex binary (plus mkiv files needed) so that one can install lmtx and run both engines. Instead of the --luatex switch one can also force the engine in the usual way with "% engine=luatex" at the top line of the source file (but no pdftex and xetex in this installer). FWIW, the lmtx installation ships with the latest experimental luatex binary but normally that should not have consequences, but it does permits testing occasional updates.

Using two versions of ConTeXt
by Jairo A. del Rio 18 Apr '20

18 Apr '20

Hi everyone! I'm using the ConTeXt version packaged with TeX Live 2020 and recently I have downloaded LMTX. Both of them work, but when I call "context" from terminal, I compile with the TeX Live version, whereas I have to use a fully specified path to get LMTX output. Is there a way to call both from terminal, say, using "lmtx" or other shortcut for the standalone version? I work on Ubuntu 18.04. Thank you in advance.

"Remember picture" does not work (again)

18 Apr '20

I've tried using the fix in https://tex.stackexchange.com/a/492197/193767 in order to make TikX's remember picture feature usable, Code below, just in case: \unprotect% This fixes the present bug\unexpanded\def\pdflastxpos{\numexpr\clf_lastxpos\relax}\unexpanded\def\pdflastypos{\numexpr\clf_lastypos\relax}% This might be needed if you run PGF 3.1.3% see https://github.com/pgf-tikz/pgf/issues/675\def\XC@tgt@mod#1{#1}\def\XC@sdef… picture] \node (A) {Node 1};\stoptikzpicture Hi world\starttikzpicture[remember picture] \node (B) {Node 2};\stoptikzpicture\starttikzpicture[overlay,remember picture] \draw (B) --++(0,0.5) -| (A);\stoptikzpicture\stoptext However, the following appears: l.1 6 120806 \lastxpos ->\clf_lastxpos <write> \noexpand \pgfsyspdfmark {pgfid1}{\the \lastxpos }{\the \lastypos } <inserted text> }\endwrite <argument> \shipoutscratchbox \page_shipout_box #1->\clf_shipoutpage #1 \relax \setbox #1\emptybox \global ... ... l.20 \stoptext I use LuaTeX 1.10 7127 + ConTeXt MkIV 2019.03.21 21:39 (TeX Live version), in case this helps. Is another fix necessary? A Metapost alternative would be fine, too.

Colors in lmt_surface and luametafun
by Otared Kavian 17 Apr '20

17 Apr '20

Hi Hans, On page 36 of luametafun.pdf there is the following example of using lmt_surface: \startMPcode{doublefun} draw lmt_surface [ preamble = "local sin, cos = math.sin, math.cos", code = "sin(x*x) - cos(y*y)", color = "f, f/2, 1-f", color = "f, f, 0", xstep = .02, ystep = .02, xvector = {-0.4, -0.4}, height = 10cm, lines = true, ] xsized .TextWidth ; \stopMPcode What is the meaning of « f » in « color = "f, f/5, 1-f" »? Is it possible to specify other colors and how can it be done? Thanks for your attention: Otared
