hz in MkIV
by Mohammad Hossein Bateni 04 Jul '16

04 Jul '16

Hi, In MkIV, the syntax for using hz seems to have changed from \setupfonthandling to \setupfontexpansion (similarly for protrusion). What is the equivalent of the following? Is this feature supported in MkIV and LuaTeX? I tried changing/adding entries to fonts.expansions.vectors.quality (and .default) to no apparent avail. \startfonthandling [hz] \defineadjustfactor A .5 \defineadjustfactor B .7 \defineadjustfactor C .7 ... \stopfonthandling In any case, I'm happy that hz works for Arabic/Farsi despite some warnings suggesting the contrary ( https://mailman.ntg.nl/pipermail/ntg-context/2008/029765.html) It does make certain Farsi texts look better, however, support for tatweel/kashida would be ideal. In fact, I was trying to see if I could somehow get it to work, building on top of hz. Hans, do you have any suggestions for this? Would this be feasible and/or worth trying? I once converted Vafa Khalighi's XeTeX-based code to Lua but ran into several setbacks. (The idea is to insert a sequence of (ZWJ,\nobreak,stretchable leader,\nobreak,ZWJ) between certain character pairs that join one another.) Here are some of the issues I faced: 1) This could not be turned off and on within a paragraph because I was hooking into processors.before action. 2) The mechanism for some (all?) center alignments (including default figure captions) interferes with what I was hacking (or, to be more precise, it's the other way around) and causes unnecessary use of tatweel in those settings. 3) Later I noticed that the added sequence did not inherit many properties (like font style or color). 4) The optimum values for the stretches I put in depend on the context, particularly because some environments manipulate \spaceskip for other reasons. Sorry for the mumbling. I can explain more if anyone is interested in helping to improve this functionality. Attached is what I have now. Thanks, MHB

RTL bug in textbackground
by Mohammad Hossein Bateni 03 Jul '16

03 Jul '16

Hello, When using \definetextbackground in RTL setting, the boundaries are not determined correctly (both for location=paragraph and location=text) and colors gets messed up. Here a sort-of-minimal example adapted from details.pdf. Is there any particular keys I should use in RTL to fix the issue? \setupcolors[state=start] \definecolor[infogray][s=0.5] \definecolor[textgray][s=0.8] \definetextbackground[intro] [backgroundcolor=infogray, backgroundoffset=.25cm, offset=.5cm, frame=on,framecolor=red, location=paragraph, color=white] \definetextbackground[subintro] [backgroundcolor=textgray, backgroundoffset=0pt, offset=0pt, frame=off, location=text, color=blue] \starttext \starttextbackground[intro] A rather common way to draw attention to a passage, is to add a background. In this chapter we will therefore discuss how to enhance your document with \starttextbackground [subintro] colorful areas that either or not follow the shape of your paragraph. \stoptextbackground\ Be warned: this chapter has so many backgrounds that you should consider wearing sunglasses. \stoptextbackground \blank[3*big] \righttoleft \starttextbackground[intro] A rather common way to draw attention to a passage, is to add a background. In this chapter we will therefore discuss how to enhance your document with \starttextbackground [subintro] colorful areas that either or not follow the shape of your paragraph. \stoptextbackground\ Be warned: this chapter has so many backgrounds that you should consider wearing sunglasses. \stoptextbackground \stoptext Thanks, MHB

Equivalent of extras option in new bibliography system?
by Nicola 03 Jul '16

In the past (MKII) I used citations of the form: \cite[extras={, p.~24}][Author:2016] The extras option seems to be ignored by MKIV's bibliography system. What is the equivalent of the above? Nicola

trying to delete an attribute reference of a non attribute node
by Marco Patzer 03 Jul '16

03 Jul '16

Hi! The following example throws the error: ! error: (nodes): trying to delete an attribute reference of a non attribute node mtx-context | fatal error: return code: 1 \setbreakpoints [compound] \useMPlibrary [dum] \starttext \startTABLE \NC \externalfigure [foo-bar] [width=\textwidth] \NC foo bar foo bar foobarfoobar \bold{aaaaaaaaaaaa} \NC\NR \stopTABLE \stoptext Sorry for the not so minimal example. In the actual text I'm not using the `dum` library, I'm including actual graphics. So I don't believe that's the issue. It might have something to do with word breaking, that's my gut feeling. What is the issue here? ConTeXt ver: 2016.06.26 19:00 Marco

No idea why. Whatever I do Terminal replies with : cannot execute binary file. Dear all, and in particular Mojca Miklavec and Jean-Pierre Delange, who reacted to my first call for help, I think I have solved my problem. Somehow I managed to get Lilypond working from Terminal. Then I placed the ConTeXt-example with the LilyPond filter that I tried to compile in the same directory als the lilypond binary. Compiling it, as usual, from TeXShop it still did not start LilyPond and the .pdf still had: "[[output file missing" where the musical example should have been. However, compiling the file from Terminal did work. Best regards, Robert Blackstone

ConTeXt and LilyPond problem
by Robert Blackstone 02 Jul '16

02 Jul '16

Dear All, I am trying to get the combination of ConTeXt and LilyPond working. I copied the example that I found on http://wiki.contextgarden.net/LilyPond , changing the setups a little (I don't have the font Adobe Jenson Pro). Processing it with mkiv from april this year and earlier produces a pdf with both zapf texts and in between the text: [[output file missing. The log-file says: --------------------- t-filter . cached output file 'lilytemp/LilyPond-ConTeXt-example-27-06-16-templilypond-0.pdf' missing. Rerunning filter sh: lilypond: command not found t-filter > file 'lilytemp/LilyPond-ConTeXt-example-27-06-16-templilypond-0.pdf' cannot be found --------------------- Indeed there is no file lilytemp/LilyPond-ConTeXt-example-27-06-16-templilypond-0.pdf . With LilyPond.app itself, using TeXShop as the editor, I have no problems. (But I have never been able to get it working from Terminal, generating only messages like "cannot execute binary file" and "Permission denied" even after running sudo chmod u+x .) What can I do about it? Thanks in advance for tips and suggestions. Best regards, Robert Blackstone

Dear list, I have the following sample: \setuplanguage[fr][patterns={fr, agr}] \mainlanguage[fr] \setupbodyfont[dejavu] \starttext \hyphenatedword{χαλεπά éligibilité} \stoptext I cannot compile it with latest beta (or with stable from 2015.05.18 12:26). The error message reads: error on line 2 in file a.tex: ! Conflicting pattern ignored Is this a bug or is there no way to load French and ancient Greek hyphenation patterns? Many thanks for your help, Pablo -- http://www.ousia.tk

I will try to find a working solution with a float. If I cannot solve my problem I will post a minimal example, although I think that to show what I would like to do but cannot do I will need a fairly large example. Do I understand correctly that you also have LilyPond.app installed? Best regards, Robert
