About filling paths, unfill, etc.
by Jairo A. del Rio 03 Nov '20

Hi everyone. I want to know if nowadays (2020) Metafun is able to do an actual unfill, like above: https://tex.stackexchange.com/questions/151068/how-can-i-fill-a-complex-pat… Example of what I want to do: \startMPpage path A, B, C; A := unitcircle shifted (-center unitcircle); A := A scaled 4cm; B := unitcircle shifted (-center unitcircle); B := B scaled 1cm; %C := (reverse B) shifted (left*1.4cm); %It works for two paths fill (reverse B)-- A -- cycle withcolor red; %fill A -- (reverse B) -- C -- cycle withcolor red; %When I try the same with three paths, a thin, unwanted line appears \stopMPpage I'm aware of unfill and I've read somewhere else about using pens instead, but I want to know if a better solution is possible. Thank you in advance. Regards, Jairo :)

A syntax sugar for ConTeXt
by Sylvain Hubert 02 Nov '20

02 Nov '20

Dear List, I'm experimenting with a new syntax for ConTeXt and would appreciate it a lot if you could give some opinions/advice on it. https://github.com/champignoom/luax Details in the README. Basically it's lua code faking tex, while remaining a decent programming language, and saving keystrokes to the level of tex compared to \ctxlua -only codes A major motivating example is the table. There are multiple implementations of table inside and outside ConTeXt, each of which uses its own ad-hoc syntax, but at the end of the day they're just mimicking 2d arrays with some variations. Here's an example in Context an excursion <http://www.pragma-ade.com/general/manuals/ma-cb-en.pdf> using xtable sugared with the new syntax: ``` \xtable.setup[ split='yes', header='repeat', offset='4pt', ] \xtable[ head={ align='middle', foregroundstyle='bold', {{nx=6, "Decline of wealth in Dutch florine (Dfl)"}}, {foregroundstyle='bold', {width='1.2cm', 'Year'}, '1.000--2.000', '2.000--3.000', '3.000-5.000', '5.000-10.000', 'over 10.000'}, }, next={ {{nx=6, align='middle', foregroundstyle='bold', "Decline of wealth in Dutch florine (Dfl) / Continued"}}, {foregroundstyle='bold', {'Year', '1.000--2.000', '2.000--3.000', '3.000-5.000', '5.000-10.000', 'over 10.000'}}, }, body={ align='middle', {1675, \{\math{22}}, '~7', '~5', '~4', '~5'}, {1724, '~4', '~4', '--', '~4', '~3'}, }, ] ``` Best, Sylvain

lmtx
by Hans Hagen 02 Nov '20

02 Nov '20

Hi, I might have uploaded a new version by accident so be careful when you update. Make a backup first. Sorry, The test suite compiles, which doesn't day all is ok as i just run it. There are no funcional changes, only a bit of conceptual reworking of some internals in the process of adapting to new features as well as protection, so \starttext \start \def\framed{oeps} \stop \stoptext is permitted, but when you run with context --overloadmode=warning you get a warning and with context --overloadmode=error the run aborts. Here is a user macro example: \frozen \def\foo{oeps} \def\foo{oeps} % warning or error \overloaded\def\foo{oeps} % okay eventually all system macros will be way more protected, being primitive, permanent, immutable to mention some of the possible properties. It's work in progress as you can imagine some pitfals and in order for it to work well quite some has to be flagged. Also, I have to play with some related additions. (This version also makes more extensive use of some new macro features but that's for later.)

multiparagraph quotation
by type＠projectivespace.com 02 Nov '20

02 Nov '20

I'm trying to get quotation marks at the beginning of each new paragraph in quotations (in ConTeXt Mk IV), as is the convention in English. Here's a minimal working example of what I have tried: \setupdelimitedtext[quotation][repeat=yes, middle="] \starttext \quotation{\input knuth } \stoptext However, it doesn't put left quotes at the start of each paragraph the way I'd like it to. I got this approach from the wiki page https://wiki.contextgarden.net/Command/setupdelimitedtext . However, I'm guessing this may have been only for Mk II since the \setupdelimitedtext doesn't seem to do anything here. (From what is said above on the wiki page, it looks like this might be only for Mk II, but I can't t tell.) I have searched the mailing list and stackexchange but haven't found a solution. I'm guessing that there's a simple way to do this that I am just not aware of. I'd appreciate any help anyone can offer me (and I'd be glad to put the solution into the wiki if that's appropriate, too). Thanks, Sciurus

index entries postponed if sections are empty
by Henning Hraban Ramm 02 Nov '20

02 Nov '20

Hi, I‘m despairing about my index – some sections contain only an image (\externalfigure), but I need to set several index entries for the image contents. The index entries get postponed until after the next chapter. I guess the problem is that there’s no (text) content, but \par and \strut didn’t help. The MWE shows that index entries in empty sections are ignored, i.e. “Something” is supposedly only on p.6: \usemodule[visual] \starttext \dorecurse{5}{% \startchapter[title={\recurselevel}] \dorecurse{5}{% \startsection[title={\fakewords{3}{5}}] \index{Something}\index{A\recurselevel} } \stopchapter } \completeindex \stoptext What can I do?

context.delayed is incompatible with some functions
by Sylvain Hubert 01 Nov '20

01 Nov '20

Dear List, I was reading Typesetting in Lua using LuaTEX <https://www.ntg.nl/maps/41/11.pdf>. By playing with the examples in the article, I found that `context.chapter(context.delayed("one"))` does not render the delayed text properly, while `context.bf(context.delayed("one"))` does. I would like to ask whether this difference is by design and, if not, whether there is any systematic way of giving delayed arguments to `context.chapter`, where by "systematic way" I'm referring to a proper use of the existing definition of "\chapter" instead of any faked duplication of it that visually resembles a chapter title. Thanks in advance. Best, Sylvain

Hi, In Context MKIV I always used the gnuplot module. I switched to Context lmtx on MS Windows but seem to have great difficulty loading the Gnuplot module. Any suggestions? Thanks jeroen

[save] [setmatrix] [restore] and [latelua] messages on terminal
by Aditya Mahajan 30 Oct '20

30 Oct '20

HI, With the recent versions of luamatatex (2020.09.20), in a moderate sized project, I get a multiple messages of on the terminal ........................................... mode = 0 [save] [setmatrix] [save] [setmatrix] [setmatrix] [restore] [restore] [literal]........................................... data = 0 w S 0 g 0 G 0 g 0 G 32.875 67.393234 m 26.511902 72.707367 20.076431 76.811981 13.572296 82.470184 c [etc] ............................................................................................................................... mode = 0 [literal]............................................................................................................................... data = % mps graphic 1: end It seems like metapost to PDF code is being printed to the terminal (not sure about that). I also see messages like: [latelua]..................................................................................... data = function: 0x5585588b4250 [latelua].......................................................................................................... data = table: 0x558557a5ab90floatblocks Any idea what is causing these and how to I disable them. Here is a minimal example for the second message and I can also try to create one for the first: \starttext \startframedtext \startTABLE \NC \input knuth \NC[nr=2] \iftrialtypesetting\else\startplacefigure [location={right,high}, title={Blah blah blah},] \stopplacefigure\fi \NC \NR \NC \input ward \NC \NR \stopTABLE \stopframedtext \stoptext

Here is the lang-txt.lua diff with labels transliterated from serbian cyrillic to latin script. Other files basically do not differ, only codes should be sorted out. Language definition stays the same. Regards, Ivan

Dear Mojca, Дана 30.10.2020. у 19:10, Mojca Miklavec пише: > Would you be willing to also prepare the latin one then? > The codes should be sorted out by Hans (potentially with some help), > but we definitely want to use "sr-latn" and "sr-cyrl". Sure, I will tomorrow create a transliteration to latin script and post diffs here. What you propose is in fact already used in some other places, I agree with you. > For the longer names there is some more freedom.

Then you > could type your text for a book once and have it typeset in both > versions without any extra effort :) As for transliteration, cyrillic to latin is one-to-one, straightforward with no exceptions. A simple table lookup is enough. Going from latin to cyrillic, there are some exceptions, but we could solve that. I can provide Hans with all that is needed. Ivan
