This workaround does the job. For those interested: The \zwnj can be prepended automatically to every node by setting "every node/.add code=\zwnj". The updated MWE now is: \usemodule[tikz] \tikzset{every node/.add code=\zwnj} \starttext \starttikzpicture \node {\color[red]{red}}; \node[xshift=30] {\color[red]{not red}}; \stoptikzpicture \stoptext Cheers, Christoph

Bug in placeformula with framed text
by Otared Kavian 06 Jul '16

06 Jul '16

Hi Hans, It seems that there is a bug in the latest beta (ConTeXt vesion: 2016.07.01 16:28) when using \placeformula with a framed text environment. The numbers for the formulas are placed incorrectly, on the left as well as on the right. Also, as one may see in the example below the numbering of the formulas begins at 2 instead of 1 at the first instance, and at it continues at 6 instead of 4 in the second instance. Below is an example (sorry if it is not absolutely minimal: I ran into this bug when updating a lecture notes which uses a left frame around \proclaim stuff). I attach the PDF showing the problem. I wonder whether this is related to the new features introduced recently for math frames. The code gives correct result with ConTeXt version 2015.05.18 12:26 from TeXLive 2015). Best regards: OK %%% begin bug-framed.tex \defineframedtext[ProclaimFramed] [width=\textwidth, frame=off, leftframe=on, framecolor=darkred, rulethickness=2pt, offset=0pt, loffset=4pt, roffset=4pt, ] \defineenumeration[proclaim] [text=, before={\startProclaimFramed}, after={\stopProclaimFramed}, style=slanted, title=yes, titleleft=, titleright={.}, alternative=hanging, number=no, width=fit, right={~}, ] \definemathalignment[Lgather][n=1,align=left] \starttext \setupformulas[location=left] \startproclaim{Some elementary properties of Landau notations} Let $(a_{n})_{n}$ and $(b_{n})_{n}$, as well as $(u_{n})_{n}$ and $(v_{n})_{n}$, be sequences of complex numbers.

\linedir in latest beta
by Mohammad Hossein Bateni 05 Jul '16

05 Jul '16

Hello Hans & Wolfgang, I just updated to the recent beta: 2016.07.01 16:28 Is that the latest version or is there something wrong with the update mechanism? In any case, most my Farsi tests are broken now and the culprit seems to be \linedir. Here is MWE: \setuphead[section][numberstyle=\righttoleft] \starttext \section{SALAM} \stoptext The error looks like the following: Undefined control sequence \spac_directions_righttoleft_hmode ...ip \linedir TRT\relax \else \scratchsk... \righttoleft ...spac_directions_righttoleft_hmode \fi \dousecurrentstyleparameter ...rentstyleparameter \fi \fi \useheadstyleandcolor ...usecurrentstyleparameter \fi \edef \currentcolorpar... \strc_rendering_initialize_style_and_color_display ... \relax \ifconditional \fon... \headnumbercontent ...!numberstyle \c!numbercolor \ifcsname \currentheadhash... ... l.14 \section{SALAM} —MHB

TikZ node and color
by Christoph Reller 05 Jul '16

05 Jul '16

Dear List, I use the latest version of ConTeXt and I have the following MWE: \usemodule[tikz] \starttext \starttikzpicture \node {\color[red]{red}}; \node[xshift=30] {\color[red]{not red}}; \stoptikzpicture \stoptext Can anybody tell me why the second node is not colored red? Aside: In LaTeX when using \color{red}{...} this tikzpicture renders correctly. For LaTeX I use TikZ version 3.0.1a, in ConTeXt it seems to be version 3.0.1. Any feedback is welcome. Regards, Christoph

Iterate through a directory
by Keith McKay 04 Jul '16

04 Jul '16

Colleagues I'm preparing a booklet of figures which are stored in a directory, however their is no structure in their naming. I could go through them all and rename them along the lines of Pict1.jpg, Pict2.jpg etc and \dostepwiserecurse as in the example below \setupexternalfigures [directory={/a/directory}] \starttext \dostepwiserecurse{1}{10}{1} { \externalfigure[Pict\recurselevel.jpg] } \stoptext However, I was wondering if was possible to iterate through the directory using a wildcard and have something like \externalfigure[*.jpg} to make it generic, or would I have to use lua. Best Wishes Keith

disabling page scaling
by Pablo Rodriguez 04 Jul '16

04 Jul '16

Dear list, I have the following sample: \setupinteractionscreen[option={paper,page}] \starttext \ConTeXt\ is awesome! \stoptext The values for the option key should enable "/PickTrayByPDFSize true" and "/Duplex /Simplex" in the PDF file. But I get an undesired "/PrintScaling /None" (I need to reduce the document to printing margins.) Checking lpdf-mis.lua, I see that there are two lists (or dictionaries, maybe [the technical term is beyond my knowledge]) controlling the printing options: pagespecs and plusspecs (both are local). page, portrait, landscape and paper involve fixed in the pagespecs dictionary. But these values don’t involve fixed in the plusspecs dictonary. How can I invoke the plusspecs dictionary from ConTeXt, so I can get duplex printing in the PDF file (or "/PickTrayByPDFSize true") without having to disable page scaling? Many thanks for your help, Pablo -- http://www.ousia.tk

prerrolling PDF fields
by Pablo Rodriguez 04 Jul '16

04 Jul '16

Dear list, I have the following sample: \def\BookTitle{{\itd A \ConTeXt\ Book}} \def\BookAuthor{{\sc The Author}} \setupinteraction[state=start, title=\BookTitle, author=\BookAuthor] \enabledirectives[references.bookmarks.preroll] \placebookmarks[chapter,section,subsection] \starttext \chapter{\BookTitle} \section{\BookAuthor} \subsection{\ConTeXt\ is \TeX, but not \LaTeX} \stoptext Is there a way that I can preroll or expand the commands so that PDF info fields have the same text as the bookmarks? And another request, could \TeX (and others) be prerolled to TeX instead of TEX? I think that there are two reasons in favor of this change: 1. From scrn-ini.mkvi: creator {ConTeXt - \contextversion}% 2. The TeXbook includes \TeX, no \TEX. Many thanks for your help, Pablo -- http://www.ousia.tk
