textext sync problem?
by Meer, H. van der 28 Aug '13

28 Aug '13

I am using textext to draw text from inside a metapost program. The drawoptions macro is used by metapost to set drawing options such as color. As I understand, the textext call is handled by the tex-side of the metapost-context system, initiated of course from the metapost side. My impression is that this occurs asynchronously, judging by the problem I encountered. On the metapost side I have: drawoptions(withcolor blue); pic := textext(labeltext); drawoptions(); % the pic is output later [cid:3EBB8ADD-F7B8-4DE1-8990-9EB0E0F45EF6@fritz.box] Deleting the reset implied by the second drawoptions does honor the coloring: drawoptions(withcolor blue); pic := textext(labeltext); [cid:8813D244-4326-4F4A-8520-3C704619954C@fritz.box] I am inclined to conclude that the calling environment containing the drawoptions setting is not captured the moment the textext call is placed, but somewhat later. Because so it can be explained why the latter has the blue color but the former does not (drawoptions has already been reset before it is taken into account). The following code variation seems to corroborate this conclusion: drawoptions(withcolor blue); pic := textext(labeltext); drawoptions(withcolor darkgreen); [cid:415E4344-B8AA-492B-B320-D57D405462EB@fritz.box] If the conclusion is correct, I have a serious problem, because it then becomes impossible to predictably change the drawoptions used by textext. The result then might be dependent on timing conditions in the system. In my opinion, calling textext should capture all relevant data at the precise moment of the call in metapost. I might be wrong, of course, but otherwise I am in need of a repair. Hans van der Meer

Documentation for EPUB conversion
by Thangalin 28 Aug '13

28 Aug '13

Hi, I ran the following simple document through ConTeXt: \setupbackend[export=yes,xhtml=yes] \enableregime[utf-8] \mainlanguage[en] \language[en] \setupexport[ title={A nice book}, author={John Doe}, firstpage={cover.jpg}, ] \starttext \startitemize \item First \item Second \item Third \stopitemize \stoptext I then ran mtxrun: mtxrun --script epub --make t.specification This produced a document with the cover page correctly; however, the items were listed on a single line in the EPUB, instead of on lines by themselves. I have a couple of questions: - *Styling.* Is custom styling required to format bullet or numbered lists in the resulting EPUB XHTML document? - *Knowledge.* Would anyone be willing to share their experiences (and tips) for transforming ConTeXt documents to EPUB? - *Examples.* Where can I find examples of simple and complex ConTeXt documents being converted to EPUB documents having a similar layout? Many thanks and kind regards.

part titles not showing up
by Henning Hraban Ramm 27 Aug '13

27 Aug '13

Hi together, I wonder why I can’t seem to get my part titles visible: %\setuphead[part]{WHAT?} \starttext \part{Bart Eins} \chapter{Gabiddel Eins} \input tufte \chapter{Gabiddel Dswei} \input tufte \part{Bart Zwei} \chapter{Gabiddel Trei} \input tufte \stoptext I also tried \startpart[title=Something] etc. to no avail. If I remember correctly, part titles shouldn't need any setup to at least show up somehow?

Unexpanded texdefinition produces “Undefined control sequence”
by Marco Patzer 27 Aug '13

27 Aug '13

Hi, the following example produces an “Undefined control sequence” error. If \def is used instead of \starttexdefinition then there is no error. Why? \starttexcode \installcommandhandler{foo}{foo}{foo} \appendtoks \setuevalue{start\currentfoo}{\foo@start[\currentfoo]}%% \setuevalue{stop\currentfoo }{\foo@stop}%% \to\everydefinefoo \starttexdefinition unexpanded foo@start [#1] \stoptexdefinition %% works %% \unexpanded\def\foo@stop{} %% produces undefined control sequence error \starttexdefinition unexpanded foo@stop \stoptexdefinition \stoptexcode \definefoo [myfoo] \starttext \startmyfoo Foobar \stopmyfoo \stoptext Marco

flow text around graphic: lower right
by Lars Huttar 26 Aug '13

26 Aug '13

Hi all, We have the small self-contained example below, in which text flows around a graphic. The graphic is aligned with the upper-left corner of the text paragraph (despite \setuphanging[location=right]). We would very much like to have the graphic align with the lower right corner of the paragraph. Is there any way to do that? \definecolumnset[TwoColumns][n=2] \setupexternalfigures[location={local,default}] \setuphanging[location=right] \starttext \startcolumnset[TwoColumns] \dorecurse{3}{ \starthangaround{\externalfigure[cow][width=2cm]} I want this cow to be in the lower right corner of the paragraph. \input knuth \stophangaround } \stopcolumnset \stoptext Versions: We're using mkii. But we get the same results for mkii and mkiv on the example above. Thanks, Lars

Thank you! I dont understand this command, what does "1ex plus 1ex minus .2ex " excactly mean? Does it mean the consecutive distance is element of the interval [0,8ex;2ex] or what? > >/ The question is, only to add an minimal distance, wich has not to be > />/ undercut while protrusing and justifying. > / > Example please > > Marco I am asking for the example :) Or what do you mean. Your example above is exactly, what I was searching for. Only the syntax have to be understood. Huseyin

Re: [NTG-context] Typesetting Classical Arabic Poetry
by J. R. Schmid 26 Aug '13

26 Aug '13

Hi Idris, thank you much for your answer and also the attached files! I've played around with your module and ran into some problems which may have been due to my inexperiencedness with ConTeXt (rupturing of ligatures, at least with Scheherazade and inconsistent line height). Marco has been helping me though, and it looks like he solved those problems while improving on your module while doing so. He doesn't seem to be done with it yet and perhaps he'll want to reply himself when he is, so I'll leave it at that for now :-) Best regards from Germany, Jonathan

Minimal word-distance?
by "H. Özoguz" 26 Aug '13

26 Aug '13

Beyond the possibility to influence the tolerance by \setuptolerance, is it possible to declare explicit the minimal allowed word-distance? I ask, because in some cases the distance between consecutive words is too low (already using \setuptolerance[verstrict]). Thanks. Huseyin

left bracket in string.format()
by Peter Rolf 26 Aug '13

26 Aug '13

Hi, Not sure if this is a bug or intended behaviour. I want to fill a TABLE row with "[<number>]", but the leading left bracket causes some problems here. I tried the syntax 'print(string.format("[%d]",10)' in pure lua and the result is as desired. %% -------------- \starttext \startluacode context.bTABLE{} context.bTR() for i = 1,8 do context.bTH() context(string.format("[%d]",i)) context.eTH() end context.eTR() context.eTABLE() \stopluacode \stoptext %% -------------- gives [..] fonts > 'fallback modern rm 12pt' is loaded setup > error in line 6, namespace '354>', key '1' setup > error in line 9, namespace '354>', key '2' setup > error in line 12, namespace '354>', key '3' setup > error in line 15, namespace '354>', key '4' setup > error in line 18, namespace '354>', key '5' setup > error in line 21, namespace '354>', key '6' setup > error in line 24, namespace '354>', key '7' setup > error in line 27, namespace '354>', key '8' [..] and empty TABLE cells. Any help welcome. Peter
