Documentation for the letter module
by Marco Patzer 21 Mar '17

21 Mar '17

Hi! Where can the current documentation for the letter module be found? I seems like it's not included in the distribution (why is it missing?) and http://bitbucket.org/wolfs/correspondence/downloads/correspondence.pdf is (out)dated: 2010-08-27 Furthermore, the latest updates on http://bitbucket.org/wolfs/correspondence/ are from 2012-02-02 and the module seems to have been updated¹ since (2015-08-24).

\showlayout values
by Pablo Rodriguez 21 Mar '17

21 Mar '17

Dear list, I have the following sample: \setuplayout[backspace=2.5cm, cutspace=2.5\backspace, rightmargin=1.75\leftmarginwidth, width=middle] \showframe \starttext \showlayout \stoptext Values equal to 0pt are written as 0ptpt. I guess this might be a typo somewhere in the code. But I would like to know the actual values of rightedge and rightedgedistance. I assume I’m missing something. But if the right margin shows its outer edge, there should be a measure that shows the distance between the right margin edge and the right paper rim. Or shouldn’t it be? Many thanks for your help, Pablo -- http://www.ousia.tk

bug in \definefontfamily? (was: Re: OT salt feature not working?)

Hi Joseph, sorry, the second sample was different. The first line was TeX Gyre Pagella and the second line was Neo Euler. The default feature for the whole text was old numbers. TeX Gyre Pagella works fine with it, but Neo Euler (with \definefontfamily) doesn’t honour "onum". But \definefont works fine, so I guess something might be improved in \definefontfamily. See the sample: \definefontfeature[default][default][onum=yes] \definefontfamily[mainface][rm][TeX Gyre Pagella] \definefontfamily[mainface][hw][Neo Euler] \definefont[directFont][euler.otf:+onum] \setupbodyfont[mainface] \starttext \startTEXpage[offset=5ex] 1110 {\hw 1110} \directFont 1110 \stopTEXpage \stoptext BTW, Neo Euler has "Neo-Euler" as PostScript name (according to otfinfo). Maybe this is causing problems to the font loading mechanism. Wolfgang, what do you think of this issue? Many thanks for your help, Pablo -- http://www.ousia.tk

\externalfigure locator
by Procházka Lukáš Ing. 20 Mar '17

20 Mar '17

Hello, is there a Lua version of external figure locator used by \externalfigure? Suppose having: ---- \setupexternalfigures[location={default,local,global},directory={../../Pics}] \externalfigure[mill] % Finds e.g. in d:\Ctx-Beta\tex\texmf-context\tex\context\sample\common\mill.png \externalfigure[MyPrettyPicture.jpg] % Finds e.g. in c:\Lukas\Pics\MyPrettyPicture.jpg ---- And I need a function like: ---- \startluacode local path path = assert(ExternalFileLocator("mill") == "d:/Ctx-Beta/tex/texmf-context/tex/context/sample/common/mill.png") path = assert(ExternalFileLocator("MyPrettyPicture.jpg") == "c:/Lukas/Pics/MyPrettyPicture.jpg") \stopluacode ---- So what to use in place of "ExternalFileLocator()"? TIA. Best regards, Lukas -- Ing.

Asymptote or Metapost and ConTeXt parameters.
by Jaroslav Hajtmar 19 Mar '17

19 Mar '17

Hello ConTeXtist, I saw the opportunity to insert an Asymptote picture into Context source code (due filter). For example here: https://mailman.ntg.nl/pipermail/ntg-context/2015/080581.html Is there a way to pass the ConTeXt parameter which influenced the creation of the Asymptote image? My point eg. the ability to define macros, which gave its parameters to Asymptote procedure or function and depending on these parameters, the image created by Asymptote looked differently. Before starting work on an illustrative example I am asking, whether it makes sense to deal with such a thing ... I suppose the impossibility of combining asymptote code and such Lua code (or not?). There is a similar possibility, at least in Metapost? For simpler pictures it would probably suffice .... Thanx Jaroslav Hajtmar

Calculating with \measure
by Marco Patzer 19 Mar '17

19 Mar '17

Hi! Is it possible to calculate with \measure or do I have to resort to dimens? Example: \definemeasure [mymeasure] [4cm] \newdimen\mydim \mydim4cm \starttext \framed[width=4cm]{Foobar} \framed[width=\measure{mymeasure}]{Foobar} \framed[width=2\mydim]{Foobar} \framed[width=2\measure{mymeasure}]{Foobar} \stoptext Marco

How to use tex.print in ctxlua
by Otared Kavian 19 Mar '17

19 Mar '17

Hi, I would like to print in a text the values of a array computed in a \startluacode …. \stopluacode combination. How can I do it properly? Please have a look at the example below and its output, which is not satisfactory because the right parenthesis is separated from the number by a space. How can I suppress this unwanted space? For instance I get (1, 103 ) instead of (1, 103). Thanks in advance for any help, Best regards: OK %%% begin ctxlua-print.tex \starttext \startluacode n = 6 ; vecteurX = {} ; for i = 1,n do vecteurX[i] = i ; end vecteurY = {} ; for i = 1,n do vecteurY[i] = 3*vecteurX[i] + 100 ; end for i = 1,n do context("(") tex.print(vecteurX[i]) context(", ") tex.print(vecteurY[i]) tex.print(")") context.par() end \stopluacode \stoptext %%% begin ctxlua-print.tex

OT salt feature not working?

Dear list, I have the following sample: \definefontfeature[default][default][salt=yes] \definefontfamily[mainface][rm][Neo Euler] \setupbodyfont[mainface] \starttext \startTEXpage[offset=1em] 1110 \type{1110} \stopTEXpage \stoptext I get the same results with or without the first line commented out. (I’m using latest beta from 2017.03.02 22:23.) Is this a bug or what am I missing? Many thanks for your help, Pablo -- http://www.ousia.tk

Dear Wolfgang, You are right. After putting “|”, the output is correct. I did right in other tables except the given one. Thank you for pointing out my mistake. Best regards, Dalyoung
