Access current element in xmlsetsetup via xml.expressions
by achim＠jander.de 02 Oct '19

02 Oct '19

Hello, I'm trying to build an xmlsetsetup with an own lua function. XML in MKIV says on pg. 33: You can also use normal Lua functions as long as you make sure that you pass the right arguments. There are a few predefined variables available inside such functions. list table the list of matches l number the current index in the list of matches ll element the current element that matched order number the position of the root of the path But I can't figure out how to get access to list, ll etc. My MWE (only for testing the access, is always true): \startbuffer[text] <para>Dies ist <inline style="sup">ein</inline> xxx<inline style="sub">zwei</inline> noch ein <inline style="sup">sup</inline> Test<inline style="sub">sub</inline></para> \stopbuffer %\enabletrackers[xml.parse,xml.path] \startluacode function xml.expressions.nextnodeatt(e) inspect(e) inspect(ll) return('sub') end \stopluacode \startxmlsetups xml:textsetups \xmlsetsetup{#1}{*}{+} \xmlsetsetup{#1}{para}{xml:*} \xmlsetsetup{#1}{inline[@style='sup'][xml.expressions.nextnodeatt(ll)=='sub' ]}{xml:sub} \stopxmlsetups \xmlregistersetup{xml:textsetups} \startxmlsetups xml:para \xmlflush{#1}\par \stopxmlsetups \startxmlsetups xml:sub \color[red]{\xmlflush{#1}} \stopxmlsetups \starttext \xmlprocessbuffer{main}{text}{} \stoptext Thanks in advance, Achim

beta
by Hans Hagen 02 Oct '19

02 Oct '19

Hi, A week ago we had the (nice and pleasant) annual context meeting and as usual some new stuff has been presented there which was not yet in the distribution at that moment. Some pending code is now being moved into the distribution. Part is font related (lmtx only, not relevant for most users), most is metafun (luametafun or metafun xl or whatever name suits) related (including a new preliminary manual) which uses some new interfaces and therefore (currently) is lmtx only. At the meeting Mojca and Harald did some experiments with the whole range of raspberry pi's (as part of upgrading the compile farm with a pi 4). The outcomes can be found at https://meeting.contextgarden.net/2019/talks/2019-09-20-harald-pi/to_pi_or_… (There are some more slides there.) Because running tex on a 4 (with plenty of memory and an external ssd) is more reasonable than on the older models, I've added an lmtx installer for the pi. Some measurements with (really) simple runs show that performance is 3-4 times less than my laptop, which is not that bad (it helps that the 4 has a decent ethernet and usb3 bus); I don't know about more complex tests.

circuitikz meters
by Martin Althoff 01 Oct '19

01 Oct '19

Hello ... I am drawing some simple circuits for an electro-physics class I am teaching using circuitikz. Using meters gives some effects I don't quite understand. The MWE works as shown. The commented lines fail with "Undefined control sequence". If I put the same 3 lines into Latex (via Texstudio on Linux), just the opposite happens. The line with rmeter fails, the other two work. Why the difference? Some version issue? The "circuitikz manual version 0.9.4.pdf" shows all 3 types of meters as choice. Actually I would prefer to use the "ammeter" and "voltmeter" within Context. Thanks for any pointers. Greetings, Martin \usemodule[circuitikz] \starttext \starttikzpicture %\draw (0,0)to[ammeter, t=A, i=$i$] ++(3,0); \draw (0,4) to[rmeter, t=V, v>=$v$] ++(3,0) ; %\draw (0,2) to[voltmeter, l=$U$] (++3,2); \stoptikzpicture \stoptext Latex MWE, works as shown \documentclass{article} \usepackage{circuitikz} \begin{document} \begin{circuitikz} \draw (0,0) to[ammeter, t=A, i=$i$] ++(3,0); %\draw (0,4) to[rmeter, t=V, v>=$v$] ++(3,0) ; \draw (0,2) to[voltmeter, l=$U$] (++3,2); \end{circuitikz} \end{document}

Does achieving the same effects (text-like kerning) for italics > and bold style still requires custom fonts? It depends on the font. A proper opentype math font should have at least the basic latin characters for test and these then if needed will have kerns and such.

Column sets (span) & unwanted vertical gap
by Procházka Lukáš Ing. 01 Oct '19

01 Oct '19

Hello, the code bellow produces unwanted vertical gap between the bottom border of the figure and the following title "A" in the first column (marked by red arrows "<->" in the PDF attached). Note that in the second column there is no such gap. I tried to play with "before", "inbetween", "beforesection" and other keys of \setuphead to remove the gap but without success. Is there a way to avoid the vertical gap? My code so far: ---- \setuppapersize[A3,landscape] \setuplayout [topspace=10mm,header=5mm,headerdistance=5mm,height=270mm, backspace=20mm,width=380mm, ] \setupheadertexts[] \setupfootertexts[] \definecolumnset[example][n=3,balancing=no] \definecolumnsetspan[wide][n=2] \setupexternalfigures[location=default] \setupindenting[no] \setupwhitespace[none] \setuplayout[grid=yes] \definehead[MyTit][title] \setuphead[MyTit] [style=\bf,color=MyBlue, before={\blank[none]},after={\blank[none]},inbetween={\blank[none]},beforesection={BS},aftersection={AS}, page=no,%grid=yes, ] % %\showframe %\showboxes %\showlayout % \starttext \startcolumnset[example] \startcolumnsetspan[wide] \externalfigure[cow][height=120mm,frame=on] %\vbox to120mm{} \stopcolumnsetspan \MyTit{A} \input knuth \MyTit{B} \input knuth \stopcolumnset \stoptext ---- Best regards, Lukas -- Ing.

Mkiv, fonts in text and math mode, with \definebodyfont
by Stefano Sanguinetti 01 Oct '19

01 Oct '19

Hello, I am trying to understand something more about fonts in text and math mode, in Mkiv Context. I would like to be able to change things at the "define body fonts" level. I tried the following, in order to have rsfs fonts : \setupbodyfont[12pt] \definebodyfont[12pt][rm][tf=rsfs10 sa *] \starttext \tf ABCD \tfa ABCD \stoptext The \tfa ABCD is displayed as rsfs as I wanted, but the \tf ABCD is displayed as default fonts. Why ? What could I change in order to have \tf ABCD in rsfs ? In math mode, I am not able to have rsfs fonts : \setupbodyfont[12pt] \definebodyfont[12pt][mm][mr=rsfs10 sa *,ex=rsfs10 sa *,mi=rsfs10 sa *,sy=rsfs10 sa *,ma=rsfs10 sa *,mb=rsfs10 sa *] \starttext $ABCD$ \stoptext That gives ABCD in default math mode fonts. Is there a simple way to do it with the \definebodyfont command ? Thank you in advance for your comments.
