Unexpected space after hyphen in xml/html export
by Rik Kabel 11 Oct '18

11 Oct '18

List, Occasionally an unexpected and unwanted space is inserted following the hyphen of a compound word in html/xml exports. In a document with about 500 such compounds, this occurs 30 times. The following input: \setupbackend [export=yes,xhtml=yes] \starttext Theocracy, the priest power; monarchy, the one|-|man power; and oligarchy, the few|-|men power|—|are three forms of vicarious government over the people, perhaps for them, not by them. Democracy is direct self|-|government over all the people, for all the people, by all the people. Our institutions are democratic: theocratic, monarchic, oligarchic vicariousness is all gone. We have no Divine vicar who is responsible to God for our politics and religion; only a human attorney, answerable to the people for his official work. The axis of rotation has changed: the equator of the old civilization passes through the poles of the new. This makes some change in the geography of both Church and State. \stopsection \stoptext Produces, in relevant part, the following xml (wrapped for convenience): Theocracy, the priest power; monarchy, the one-man power; and oligarchy, the few- men power—are three forms of vicarious government over the people, perhaps for them, not by them. Democracy is direct self-government over all the people, for all the people, by all the people. Our institutions are democratic: theocratic, monarchic, oligarchic vicariousness is all gone.

It is thought by many to be the inspiration for part of Lincoln's Gettysburg Address.) -- Rik

Implicit plots/level curves possible?
by Mikael P. Sundqvist 11 Oct '18

11 Oct '18

Dear list, Is it possiblet to make implicit plots (i.e. ploting the curves described by equations) in MetaFun? I cannot find anything about them in the MetaFun manual. For example, in Mathematica I can write something like ContourPlot[2 x^5 + x y + y^5 == 0, {x, 0, 2}, {y, -2, 1/2}] to get the attached figure. The closest I have found which is something MetaPost-like, is the levelcurve command in mfpic (see for example this answer https://tex.stackexchange.com/a/405527/52406) If this is not currently possible in MetaFun, what is the simplest way to proceed (I want the same style of the plots as the other ones in my doc)? Is it to 1) somehow run mfpic from within ConTeXt? 2) export points from Mathematica and plot them in ConTeXt (how could that be done?). In the latter case, say I have the points (0,0), (0.4,1), and (0.8,2) exported to a file. What format should it be in to be easily imported and plot in MetaFun? 3) some other way? /Mikael

embedded sounds
by Pablo Rodriguez 10 Oct '18

10 Oct '18

Hi Hans, this is a lighter version from sound-001.tex from your test samples: \definerenderingwindow [example] [width=0pt,height=0pt,frame=off] \setupinteraction[state=start] \useexternalrendering [mysound] [audio/x-mp3] % audio/x-mp3 [sound.mp3] %~ [embed] \definereference [StartSoundTrack] [StartRendering{mysound}] \definereference [StopSoundTrack] [StopRendering{mysound}] \definelayer[resources][width=\paperwidth,height=\paperheight] \setupbackgrounds[page][background=resources] \setupbodyfont[100pt] \starttext\bf\ss \setlayer[resources]{\placerenderingwindow[example][mysound]} \startTEXpage \button{start}[StartSoundTrack] \button{stop}[StopSoundTrack] \stopTEXpage \stoptext As reported before (https://mailman.ntg.nl/pipermail/ntg-context/2018/092327.html) sound is played fine when not embedded. But it won’t play embedded files. Without embedded sound, the relevant /Filespec reads: 7 0 obj << /F (sound.mp3) /Type /Filespec >> endobj With an embedded sound, /Filespec and /EmbeddedFile read: 7 0 obj << /Subtype /audio#2Fx-mp3 /Type /EmbeddedFile /Length 49006 >> stream endstream endobj 8 0 obj << /EF << /F 7 0 R >> /F (sound.mp3) /Type /Filespec /UF (\376\377\000s\000o\000u\000n\000d\000.\000m\000p\0003) >> endobj 10 0 obj << /EF 8 0 R /F (sound.mp3) /Type /Filespec >> endobj I don’t know why there are two /Filespec objects, since they are duplicated. In any case, the value for the /EF entry has to be a dictionary that points to the /EmbeddedFile (such as in object 8). I’m afraid that the code that generates the second /Filespec object (object 10 in the code above) is wrong. I attach a modified file fixing the issue from the PDF document generated by ConTeXt. I hope this help to fix the issue. Many thanks for your help, Pablo -- http://www.ousia.tk

Addressing glyphs in Lua
by Marco Patzer 10 Oct '18

10 Oct '18

Hi! I have two questions regarding addressing glyphs in Lua: 1) How to address glyphs in slots as e.g. U+F0029? 2) How to address glyphs by name? Use: \startluacode fonts.handlers.otf.addfeature { name = "foo", type = "substitution", data = { [0xF0029] = 0xF0030 }, -- ← doesn't work } \stopluacode Marco

\noheaderandfooterlines to suppress header frame, too
by Procházka Lukáš Ing. 10 Oct '18

10 Oct '18

Hello, this may have been posted here some time before, but - would it be possible to extend \noheaderandfooterlines command to temporarily suppress bottom frame, too? Suppose having the following code: ---- \setupheadertexts[left][right] \setupbackgrounds[header][bottomframe=on] \starttext \input knuth \page \noheaderandfooterlines \input knuth \stoptext ---- - On the page #2, header is not shown, which is OK, but header (bottom-)frame is still drawn, which is unwanted...

This one worked for me: context.setupexternalfigures { directory = 'images,' .. resolvers.expandpath('IMG_PATH') } Thanks, Gilles

line break after \item, but not \stopitem
by Damien Thiriet 09 Oct '18

09 Oct '18

Hi list, I am designing a presentation for my pupils (some loooong exercices to learn LibreOfficeDraw by doing). To be sure that they don't misview any question, I decided to force a pagebreak after each first level item. A question on TSE gave me the proper key to \setupitemize, but I am facing an issue I didn't expect. Given this MWE \setuppapersize[S6] \setupitemize[1][inbetween={\page}] \starttext \startitemize[n] \startitem \input knuth \stopitem \startitem \input ward \startitemize[a] \startitem first point \stopitem \startitem second point \stopitem \stopitem \stopitemize \stoptext I expected a page break after each 1 level \stopitem, that is after knuth's text and "second point". However the text is breaking before first point, that is at the beginning of level 2 startitemize, which is AFAIK semantically part of a level 1 item. Do you have any idea to force page break *after* "second point" and not *before* "first point" ? Thanks, Damien Thiriet
