Item group parentheses
by Jairo A. del Rio 07 Jan '20

07 Jan '20

I'm defining item groups in ConTeXt and I find the following issue: combining the "text" parameter with others automatically disables "left" and "right" keys, so numbers always appear enclosed in parentheses. %What I expect: %I. This ain't right %What I get: %(I) This ain't right \defineitemgroup[erroneous] \setupitemgroup[erroneous][1][R,text,continue][left=,right=.,stopper=] \starttext \starterroneous \startitem This ain't right \stopitem \stoperroneous \stoptext Maybe a bug, I want to know how to get the expected result. Thank you in advance.

Indentation problem inside enumeration
by Mikael P. Sundqvist 03 Jan '20

03 Jan '20

Hi! I've met a strange problem with indentation in consecutive enumerations. It seems to me that if 1) the first enumeration uses indentnext=no AND 2) the next enumeration uses a background then the second(?) paragraph of the second enumeration is not indented. Here is a small example (see what lines to comment to avoid the problem). %%% \defineenumeration[losning][ text=Lösning, title=yes, alternative=serried, width=fit, number=no, headstyle={\em}, titlestyle=, indentnext=no,% another way to get indentation is to comment this line indenting={yes,medium}, ] \defineframedtext[anmärkningsbakgrunden][ width=\textwidth, background=color, backgroundcolor=gray, ] \defineenumeration[anmarkning][ text=Anmärkning, title=yes, headstyle={\definedfont[Bold*default]\WORD}, alternative=serried, width=fit, number=no, prefix=no, indentnext=no, indenting={yes,medium}, before={\startanmärkningsbakgrunden},% if these two lines are commented then after={\stopanmärkningsbakgrunden},% the indentation works ] \starttext \startlosning This environment destroys indentation in the next. \stoplosning \startanmarkning This is just a first paragraph. This paragraph should be indented. This paragraph is always indented. \stopanmarkning \stoptext %%% (This is a stripped down example with some settings removed. But it shows the point.) Am I doing something wrong? The resulting pdf is attached. /Mikael PS I think I saw this problem both with mkiv and lmtx.

last beta this year
by Hans Hagen 01 Jan '20

01 Jan '20

Hi, I uploaded the last beta for this years so we will leave all old bugs behind us. Here's a bit of agenda: - mkiv will use luatex so as part of the upcoming tl code freeze that needs the usual testing; - next year i suppose that lmtx will be used by the majority of users - we need to (read mojca and i will do that when we're in the mood) adapt the garden infrastructure for installing lmtx; part of that is also the context repository - we have to think about how to deal with the extra modules as part of that (basics are already there) - idris, mohammad, wolfgang and i are trying to make right-to-left handling of layout related items more complete and consistent, expect more next year - i expect to do some more luametafun stuff, maybe some cleanup of old code, maybe a bitmore split between old mkiv and new lmtx - i also want to do some pending font trickery, probably lmtx only - wolfgang (he doesn't know that yet) and i (and maybe some others) are going to think about some lightweight protection of core macros (using some new lmtx features) .. i'm curious to know if and how frequently users are bitten by accidental redefinitions - aditya (he knows) has to pick up on some pending math issues so math will get better too - thomas (he also knows as he needs it) and i are looking into some tricky layout things related to synchronizing content - i want to see if the installation can be more automatic (as we basically need a real minimalistic copy-end-run approach in for instance texlive for lmtx) - i need to move some pending stuff into all kind of manuals (but will probably forget about it unless i run into new cd's to keep me occupied while doing it) - there will be a ctx meeting in czech (at the place we've been before) - in addition, next year will see the wiki being improved, something Taco and Pavneet and others are / have been working on; feel free to contribute to that effort! So, upto next year, Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

Re: [NTG-context] ntg-context Digest, Vol 186, Issue 61

Dear Hans, I read the “luametafun.pdf” and run the codes one by one. It is a really nice to have those figures easily. During the reading, I found that there is a difference between the figure in the manual and the output of my run. I run the following code at page 24-25 in “luametafun.pdf”. \startMPcode{doublefun} draw lmt_contour [ xmin = 0, xmax = 4*pi, xstep = .05, ymin = -6, ymax = 6, ystep = .05, levels =7, height = 5cm, preamble = "local sin, cos = math.sin, math.cos", function = "cos(x) + cos(y)" background = "bitmap", foreground = "edge", linewidth = 1/2, cache = true, ]; \stopMPcode In the output, the background of text is gray while the background of text in the manual is white. Here are versions of LuaMetaTeX and ConTeXt which I use. %%%%%%% This is LuaMetaTeX, Version 2.03.4 open source > level 1, order 1, name 'cont-yes.mkiv' system > system > ConTeXt ver: 2019.12.16 18:54 MKIV beta fmt: 2019.12.17 int: english/english system > %%%%%%%%% Is there anything that I miss? Would you please to check it? Thank you. Best regards, Dalyoung

Coding for new Unicode characters
by Richard Mahoney | Indica et Buddhica 29 Dec '19

29 Dec '19

I am using Latin Modern Roman to typeset some proceedings and need the following characters in regular, italic, and small caps: Character: ṉ U+1E49 Name: LATIN SMALL LETTER N WITH LINE BELOW Character: Ṉ U+1E48 Name: LATIN CAPITAL LETTER N WITH LINE BELOW Character: ḻ U+1E3B Name: LATIN SMALL LETTER L WITH LINE BELOW Character: Ḻ U+1E3A Name: LATIN CAPITAL LETTER L WITH LINE BELOW Character: ṟ U+1E5F Name: LATIN SMALL LETTER R WITH LINE BELOW Character: Ṟ U+1E5E Name: LATIN CAPITAL LETTER R WITH LINE BELOW These characters are available in Computer Modern Unicode (although not, it seems, in small caps). Still, I would prefer to still with LM. I'm wondering if there is a way in Context to set up these characters on the fly, say with something along the lines of "newunicodechar"? \newunicodechar{<char>}{<code>} \newunicodechar{ā}{\accent"0304 a} newunicodechar -- Definitions of the meaning of Unicode characters https://ctan.org/pkg/newunicodechar?lang=en Best, Richard -- Richard Mahoney | Indica et Buddhica Littledene Bay Road Oxford NZ T: +6433121699 M: +64210640216 r.mahoney(a)indica-et-buddhica.org https://indica-et-buddhica.org/

How to use in Metafun, a function defined in Lua
by Otared Kavian 28 Dec '19

28 Dec '19

Hi all, I would like to use a math function defined in lua in Metafun in order to draw its graph, together with the graphs of some other functions. As a simple example consider the following: %%% begin lua-metafun-example.tex \startluacode function document.myfunction(n,x) local S S = math.sin(n*x) return S end \stopluacode \starttext Here \type{document.myfunction(n,x)} is $\sin(nx)$. For instance when $n = 2$ and $x = 355/113$ we have: \type{document.myfunction(2,355/113)} $=\cldcontext{document.myfunction(2,355/113)} \sim 0$. \startplacefigure[title={Nothing works\dots}] \startMPcode{GridAxis} numeric gu ; gu = 5mm ; % gu = graph unit draw image ( draw function (1,"x","document.myfunction(2,x)", % <-- this does not work % draw function (1,"x","sin(2*x)", % <-- this works -355/113,355/113,.01) scaled gu withpen pencircle scaled .075pt withcolor darkred ; ) xsized .7TextWidth ; \stopMPcode \stopplacefigure \stoptext %%% end lua-metafun-example.tex Here one sees that the function « document.myfunction » is well defined in Lua and is known in ConTeXt, but I cannot use it in a Metapost code: how can one do that? Thanks in advance for any help. Best regards: Otared

issues with attachments
by Pablo Rodriguez 27 Dec '19

27 Dec '19

Hi Hans, I accidentally discovered that file attachment generates two entries in Acrobat, such as this sample: \setuppapersize[A5] \showframe \setupinteraction[state=start] \setupinteractionscreen[option=attachment] \starttext a\attachment[file=xml-mkiv.pdf, name={attached.pdf}] \stoptext This happens with latest beta (from 2019.12.17) in both MkIV and MkXL. https://www.pdfa.org/wp-content/uploads/2018/10/PDF20_AN002-AF.pdf#search=u… warns about the use of both /EmbeddedFiles and /FileAttachment annotations. Acrobat seems to be the problematic software. I think it is fine to have /FileAttachment annotations for "method=normal" and /EmbeddedFiles for "method=hidden". Would be also possible that the entries in /Embeddedfiles use the value for "name" instead of "file" (when specified)? And for the /EmbeddedFile annotation, would it be possible to add the value for /Size entry (uncompressed size of the file in bytes, https://www.adobe.com/content/dam/acom/en/devnet/pdf/PDF32000_2008.pdf#page…) in the /Params dictionary? This is the way to avoid that Acrobat displays no uncompressed size but real uncompressed size (I guess both values would be very similar, when not the same). Many thanks for your help, Pablo -- http://www.ousia.tk
