directlua in xml-environment
by Meer, Hans van der 17 Nov '16

17 Nov '16

Here is something I do not understand. Possibly I am doing something wrong. The following code is fine, within <<>> the current contextversion is printed. \def\mymacro{\directlua{tex.print("\\contextversion")}} \starttext calling mymacro <<\mymacro>>\par \stoptext However calling \mymacro from inside \startxmlsetup .. \stopxmlsetup does not work and results in <<\contextversion>>. I guess that the catcode regime in that environment is to blame. But how do I change that in order to get things working? I looked into the LuaTeX-manual where catcodes in relation to tex.print are treated, but in vain and could not find how to. What do I have to change? Hans van der Meer

Combo fonts in MKIV
by Henri Menke 15 Nov '16

15 Nov '16

Dear list, On http://tex.stackexchange.com/a/314401/10995 I saw that LuaTeX has support for combo fonts where one can select different fonts and features for selected glyph ranges. Is there an interface in MKIV for that? I couldn’t find anything in fonts-mkiv.pdf. Cheers, Henri

Another question about definerefereformat
by Benjamin Buchmuller 13 Nov '16

13 Nov '16

Here is another question, I was wondering about. What is the ConTeXt’s way to provide the “right” (or “left”) argument when \definereferenceformat[text=…] is set? Starting from this example: \starttext \definereferenceformat[infig][text={Figure }] \startplacefigure[reference=fig:A] Some figure. \stopplacefigure This is \infig[fig:A]. \stoptext I would like to output “This is Figure 1 a.” Obviously I can type “This is \infig[fig:A]\,a.” to get the desired result; however it does not seem very “ConTeXt-ish” to me as “This is \in{Figure}{a}[fig:A].” is much more concise. Is there the possibility to have something like \infig[right=a][fig:A]? Thanks again. Benjamin

Setupreferencing[interaction=text] breaks referenceformat[text={…}]
by Benjamin Buchmuller 13 Nov '16

13 Nov '16

Hi, I’m not sure if this is the intended behaviour of the system, but I want to typeset “This is Figure 1.1 in Chapter A Good Story” in the attached minimal example. However, setting up the referencing interaction to text, this typesets “This is 1.1 in Chapter A Good Story”. The same holds true, when the reference format is not defined via \definereferenceformat, but also in \in{Figure}[fig:A]. Here is the minimal example: \starttext \setupreferencing[ left={}, right={}, interaction=text, % critical ] \definereferenceformat[infig][text={Figure }] \chapter[myreference]{A Good Story} \startplacefigure[reference=fig:A] Some figure. \stopplacefigure This is \infig[fig:A] in Chapter \about[myreference]. \stoptext Thank you very much for your help.

Problem with lucida
by Eric Detrez (Info) 12 Nov '16

12 Nov '16

I've got a curious problem with lucida. Characters have ascii code shifted by -1 (note the kerning) Minimal example : \usetypescript[lucida] \setupbodyfont[lucida,10pt,rm] \starttext abcdefgh \stoptext I join the pdf file with the result. Other fonts are fine in context, Lucida fonts are fine with Latex ...

\xmlchainatt behaviour
by Meer, Hans van der 11 Nov '16

11 Nov '16

I might be doing wrong, but for now I have the strong impression that \xmlchainatt is at fault. It does not break the callchain as soon as a match is found. Also according the manual xml-mkiv, \xmlchainatt{#1}{testx}{no-test} should return "no-test" but returns nothing. I would very much helped if these macros react is I thin they should. Is this my fault? Hans van der Meer Minimal example % test chainttribute failure. \startxmlsetups demo:chainatt \xmlsetsetup{#1}{root|node|innernode}{demo:chainatt:*} \stopxmlsetups \xmlregisterdocumentsetup{demo}{demo:chainatt} \startxmlsetups demo:chainatt:root root: xmlatt <test> = <\xmlatt{#1}{test}>\crlf root: xmlchainatt <test> = <\xmlchainatt{#1}{test}>\crlf \xmlall{#1}{*} \stopxmlsetups \startxmlsetups demo:chainatt:node -- node: xmlatt test = <\xmlatt{#1}{test}>\crlf -- node: xmlchainatt <node> = \xmlchainatt{#1}{test}\crlf -- node: xmlchainattdef <node> = \xmlchainattdef{#1}{notest}{no-test}\crlf \stopxmlsetups \startxmlsetups demo:chainatt:innernode ---- innernode: xmlatt test = <\xmlattdef{#1}{test}{nono}>\crlf ---- innernode: xmlchainatt <test> = \xmlchainatt{#1}{test}\crlf \stopxmlsetups \startbuffer[chainatt] <root test="abc"> <node test="pqr"> <innernode test="xyz"/> </node> </root> \stopbuffer \starttext \ConTeXt-version=\contextversion\blank Manual on xml-mkiv page 22 on \tex{xmlchainatt} reads: returns the value of attribute NAME or empty if no such attribute exists; backtracks till a match is found\blank \xmlprocessbuffer{demo}{chainatt}{}\blank However, does not stop when backtracking finds "a match". \stoptext

Chemical reaction...
by Willi Egger 10 Nov '16

10 Nov '16

I am busy to edit an older article in which there are a couple of chemical fromulas and reactions. However, I am stuck because the following throws me an error when uncommenting the line with “\chemical{2H^\oplus}{~waterstof (zuur)}” (something with $ inserted…) Another aspect is, that the {DEZ} does not appear. Further the {zinkion} and {ethan} appear not as text under the formula but as text next to it. \starttext \placeformula \startformula \chemical{(C_2H_5)_2Zn}{DEZ} \chemical{PLUS} % \chemical{2H^\oplus} {waterstof (zuur)} \chemical{GIVES} \chemical{Zn^{2\oplus}}{zinkion} \chemical{PLUS} \chemical{2(C_2H_6)}{ethan} \stopformula \stoptext Thank you for hints, what I am missing here… Kind regards Willi

Creeps (binding gutter / margin correction in imposition)
by Henning Hraban Ramm 10 Nov '16

10 Nov '16

Hi together, this is not really a practical request, but an interesting (I think) idea... ConTeXt can do simple imposition (arranging pages on sheets, see \setuparranging), but in professional imposition you need to compensate for the paper thickness in folds to keep pages readable - you can move the outer pages of a fold out of the gutter (spine), or move the inner pages to the spine. (This is called creep in English, Bundversatz in German.) That means, your outer margin will have different width, depending on the position of the page in its fold. See e.g. https://helpx.adobe.com/indesign/using/printing-booklets.html A guy on the LilyPond mailing list had the interesting idea to adapt the line width to this creep, to keep an even outer margin - it would mean that TeX needs to know about imposition while breaking lines. What do you think? Greetlings, Hraban --- http://www.fiee.net http://wiki.contextgarden.net GPG Key ID 1C9B22FD

Typing in natural width box
by Henri Menke 09 Nov '16

09 Nov '16

Dear list, To answer this question on TeX.SX https://tex.stackexchange.com/questions/338135/ I was trying to put a typing environment into a natural width box. It first seemed that framedtext is doing what I was after but it turned out that only the frame is adjusted to natural width, the underlying box is still full width. Therefore I tried framed but there I obtain spurious vertical space out of nowhere. How can I place typing into a natural sized box? Cheers, Henri --- \starttext \ruledhbox{% \startframedtext[width=fit,offset=0pt] \starttyping print("Hello World!") \stoptyping \stopframedtext } \ruledhbox{% \startframed[width=fit,align=right,offset=0pt] \starttyping print("Hello World!") \stoptyping \stopframed } \stoptext
