I need to have text wrap around figures. Is this automatic? The discussion of placing figures In chapter 16 does not cover this point. -- John Culleton Wexfordpress Book design and indexing.

Custom pretty printer pass option to buff-imp-<mycustomformat>.lua
by Lorenz 22 Jan '17

22 Jan '17

I'm customizing a pretty printer and referencing the buff-imp-lua.lua and buff-imp-lua.mkiv files. I'd like to add a conditional to the .lua file say buff-imp-custom.lua. What is a good way to pass an option from my .tex file to conditionally format with the pretty printer? I'd like to use the same buff-imp-custom.lua and .mkiv pairs of files instead of creating multiple files. The .mkiv file defines e.g.: \definetyping [CUSTOM1] [\c!option=custom] I'd like to add say CUSTOM2 but pass an option that would be visible to the same buff-imp-custom.lua file. Perhaps something like this?: \definetyping [CUSTOM2] [\c!option=custom,<option visible to same lua file as CUSTOM1?>] Thanks -- Lorenz

nested colors problem

Hi, the nested color inherits the transparency from it's surrounding color. \definecolor[colA] [r=0,g=0,b=0.01,t=0.2,a=1] % transparent \definecolor[colB] [r=.278431,g=.235294,b=.545098] % opaque \starttext \startcolor[colA] \definedfont[SansBold at 96bp]Titanfall\, \startcolor[colB]2\stopcolor \stopcolor \stoptext ConTeXt version: 2014.11.26 21:43 Maybe intended behaviour, maybe a bug. Donno. Best wishes, Peter

dorecurse problem
by Rik Kabel 20 Jan '17

20 Jan '17

ConTeXters, When \dorecurse is active in the following MWE, the lines of text are overprinted. At least, this is the case for me, please confirm it for yourself. When \dorecurse is disabled, the lines print as they should, separately. Please tell me what I am doing wrong with this, if anything, and how to fix it. (Running ConTeXt ver: 2017.01.17 17:37 MKIV beta fmt: 2017.1.19 on Win10 x64. There are no errors in the log.) \definelayer [blocks] [width=\textwidth, height=\textheight] \setupbackgrounds [page] [background=blocks] \starttext \dorecurse{1}{ % comment to clear error \startstandardmakeup \setlayerframed [blocks] [preset=lefttop, frame=off, align=right]{ \startlines Line one on the left Line two on the left \stoplines } \setlayerframed [blocks] [preset=righttop, frame=off, align=flushright]{ \startlines thgir eht no eno eniL thgir eht no owt eniL \stoplines } \stopstandardmakeup } % comment to clear error \stoptext -- Rik

\setupinteraction[focus=standard] not working
by Christoph Reller 20 Jan '17

20 Jan '17

Dear List, First of all: Thank you Hans and folks for supporting focus=standard for many things. There are, however, some major places where focus=standard does not work correctly yet. I pick out the simplest and in my opinion most severe one: Floats. \setupexternalfigures[location={local,global,default}] \setupinteraction[state=start, focus=standard] \starttext \about[figure]. \page \placefigure[][figure]{Figure}{\externalfigure[cow.pdf]} \page \input tufte \stoptext The link text on page 1 in the resulting PDF correctly displays "Figure" and the overlayed PDF annotation has a seemingly correct destination "(figure)". But, in the PDF catalog's "Names"-tree the only named destination present has the name "(#1)". This destination points to the correct location on the correct page, it is only the name that should read "(figure)" instead of "(#1)". Please consider fixing at least this issue (even if you are not very fond of focus=standard ;-), as it will be of tremendous value for many users. If I can be of any help, then please let me know. Regards, Christoph

Using Asymptote in ConTeXt
by Mathias Schickel 19 Jan '17

19 Jan '17

Dear ConTeXt users, presently I try to use asymptote to render a graphic in a ConTeXt document using the module filter. I have found some suggestions on this mailing list how this can be done: https://mailman.ntg.nl/pipermail/ntg-context/2015/080581.html <https://mailman.ntg.nl/pipermail/ntg-context/2015/080581.html> I replaced the asymptote code with my own one and everything works fine. But if I use LaTeX together with the asymptote package I get an interactive 3D graphic (if I open the output with Adobe Acrobat). To do this I compile my attached file LuaLaTeX-asymptote.tex and then I compile the asymptote code via the command asy LuaLaTeX-asymptote-*.asy in the console. If I compile the LaTeX document again the result is the attached pdf LuaLaTeX-asymptote.pdf that contains the interactive graphic. Can I achieve the same using ConTeXt if I modify the attached code example I used? What do I have to modify? Best regards Mathias Schickel

Vertical space around displayed formulas
by Nicola 18 Jan '17

18 Jan '17

Hello, has something been changed in the last few months in the vertical spacing of displayed formulas, frames or other environments? I am re-typesetting some presentations using the latest beta and the content of slides (especially those containing formulas) now tends to flow to the next page, while before it used to fit in one page. I paste below an example, if that helps. I am using a system font, so you may not be able to reproduce my problem without it. Is there something I should change in my documents?

How to define a TeX logic function with a boolean returned from a Lua function and \edef fixed value

Dear sirs, Is there a way to compare, in TeX environment, a value returned from a lua function with a TeX variable? Please see this code: \def\aleatorioValue{ \startlua local nu = math.random(1,10); if nu<5 return 1 else return 0 end \stoplua } \edef\controlValue{1} \edef\inferior{Number too small \\} \edef\superior{Number too big \\} \def\myfunction{\ifx\aleatorioValue\controlValue\inferior\else\superior\fi} \starttext \dorecurse{20}{\myfunction} \stoptext Thanks a lot.
