Text on curves
by Keith McKay 23 Apr '19

23 Apr '19

I have been trying to typeset text onto curves and have been successful with the help of the MetaFun manual, and the followtext command which I saw in some correspondence between dr Hans van der Meer and Hans Hagen on the mailing list in January this year ( the subject was Double Follow Tokens). The followtext command seems to used for a simple line of text and if I increase the number of words in the line the font size is reduced to make it fit to the length of the curve (see MWE below). I would like to typeset complete paragraphs on the curve(s) and the only way I see of doing this without the font size changing is to manually create each line separately. Is their a way where this can be done by MetaFun automatically rather than manually? It would be really nice if I could create a number of curves and then MetaFun typsets a paragraph of text on to them. Also, can other options be used with followtext e.g. \input file? I'm a complete novice with MetaFun so any advice appreciated. Best Wishes Keith McKay ----Minimum Working Example---- \starttext Two different lengths of text on the same curve showing font size being reduced. \blank \startMPcode path q; q := function (1, "x", "sin(2x)" , 1, 10, .01) scaled 1.5cm ; draw followtext(q, "some text but not that long. But here and there and everywhere the text can become longer"); draw followtext (q shifted (0cm,-2cm), "some text but not that long. But here and there and everywhere the text can become longer and longer and longer finally ending here."); \stopMPcode Some other examples of text on a curve \blank \startMPcode path p; p := reverse halfcircle xyscaled 55mm ; draw followtext(p, "some text but not that long"); \stopMPcode nice spiral shape with text \startMPcode z0 = (0,0); z1 = (60,40); z2 = (40,90); z3 = (10,70); z4 = (30,50); path p; p = (z0..z1..z2..z3..z4) ; draw followtext(p scaled 1mm, "some text but not that long. But here and there and everywhere the text can become longer"); \stopMPcode \stoptext

Hello All!

Processing XML: Header and footer, data manipulation
by Axel Kielhorn 22 Apr '19

22 Apr '19

Hello, Pablo Rodríguez wrote in „From pandoc to ConTeXt“: „So, if I was able to do this, probably anybody can do it.“ Well, I tried and indeed it isn’t as difficult as i thought. (Once I learned that an entity must not contain non-ASCII characters.) Some questions remain: I want to set page headers based on information I get from the XML: \startxmlsetups xml:prozess \mainlanguage[de] \setupheadertexts[\bf\xmltext{#1}{/pnr} \xmltext{#1}{/pname}][\date] {\bTABLE \setupTABLE[frame=off] \setupTABLE[offset=1mm] \setupTABLE[c][1][align=right, width=14cm] \setupTABLE[c][2][align=left, width=6cm] \setupTABLE[c][3][align=right, width=4cm] \bTR \bTD \bfb\xmltext{#1}{/pnr} \eTD \bTD Version: \eTD \bTD \bf\xmltext{#1}{/pversion}\eTD \eTR \bTR \bTD \bfb\xmltext{#1}{/pname} \eTD \bTD Verantwortlich: \eTD \bTD \bf\xmltext{#1}{/pverantwortlich}\eTD\eTR \eTABLE} \blank \xmlflush{#1} \stopxmlsetups This works on the first page (when the document has more than one page) but headers and footers are empty on subsequent pages. Something (xmlflush?) overwrites my setup. Any idea how I can fix that? I want to use xmlconcat here, since there may be more than one docan, but I only get the „, “ \startxmlsetups xml:psoutdoc % \inmargin{\xmltext{#1}{/docan} $\Leftarrow$} {\bf \xmltext{#1}{/docnr}}\xmlflush{#1} \inmargin{\xmlconcat{#1}{/docan}{, } $\Leftarrow$} {\bf \xmltext{#1}{/docnr}}\xmlflush{#1} \xmlsave{#1}{outfile.xml} \blank \stopxmlsetups I want to write the nodes psindoc and psoutdoc to a separate file. \xmlsave overwrites the file, is there a way to append to the file? (or append to a buffer and write the buffer?) \startxmlsetups xml:psindoc \inmargin{\xmltext{#1}{/docverantwortlich} $\Rightarrow$} {\bf \xmltext{#1}{/docnr}}\xmlflush{#1} \xmlsave{#1}{outfile.xml} \blank \stopxmlsetups Can I add child notes to #1? The last two questions probably require LUA, what is a good way to start learning LuaTeX? I enclosed a small test file. Greetings Axel PS: This may result in an article for „Die TeXnische Komödie“.

\abovedisplayshortskip
by Mikael P. Sundqvist 22 Apr '19

22 Apr '19

Hi, is \abovedisplayshortskip inserted in formulas that come after short lines? Or is there a more ConTeXt-way to tune this? Small example file below, but I see no change after I set it, so I guess it is not used? /Mikael \starttext Foo \startformula 1+1=2 \stopformula \abovedisplayshortskip = -12pt Foo \startformula 1+1=2 \stopformula \stoptext

optional hyphenation patterns in ancient Greek
by Pablo Rodriguez 22 Apr '19

22 Apr '19

Dear list (especially Thomas and Arthur), I opened a request for optional hyphenation patterns at GitHub (https://github.com/hyphenation/tex-hyphen/issues/34) I’m not advocating changing the default, but only providing hyphenation patterns that allow hyphenating consonant pairs that cannot be at the word beginning. I think it may make sense to discuss the issue there (@ GitHub). Many thanks for your help, Pablo -- http://www.ousia.tk

Manipulating the pagenumber in the TOC
by Willi Egger 21 Apr '19

21 Apr '19

Hi all, "when manipulating in one area you will have to manipulate also in other aeras” I must confess. I asked some time ago about manipulating the pagenumber. Wolfgang provide me the following approach: \cldcontext{“\letterpercent.0f”,(\pagenumber+1)/2} This works indeed fine. However now I am confronted with the fact, that in the TOC the manipulated pagenumbers should be taken into account. Wolfgang’s approach does not help and ends in an error: \define[1]\SectionTOCPagenumber{ \cldcontext{“\letterpercent.0f”,(\pagenumber+1)/2}} \setuplist [section] [pagecommand=\SectionTOCPagenumber] My question is: is there a way to manipulate the pagenumber in the TOC such, that it reflects the pagenumbers in the document? Kind regards Willi

Hi, I'm trying to create a style with a left border in the margin. I want the border to start and stop with the text. For the bottom I used framedepth but the bar still goes too far on the top? \showframe \showboxes \defineframedtext[leftbartext][ width=broad, frame=off, leftframe=on, rulethickness=.5ex, offset=-\framedparameter{rulethickness}, frameoffset=\dimexpr\leftmargindistance + \framedparameter{rulethickness}\relax, framedepth=-\framedparameter{frameoffset}, ] \starttext \startleftbartext \input knuth \stopleftbartext \stoptext Regards, Gilles

Thanks, but don't bother if I'm the only one using this formatting. I've lowercased the switch name in the wiki section.
