Hi, the latest beta has a problem with fieldstacks. \setupinteraction[state=start] \definefieldstack[symbollist][symbol1,symbol1][frame=off] \definesymbol[symbol1][1] \definesymbol[symbol2][2] \starttext \fieldstack[symbollist] \stoptext PS: Is it possible to change \ctxlatetua to \ctxlatelua in the MkIV version of \savetwopassdata (core-two.mkiv).

Metapost and mkiv
by Otared Kavian 07 Nov '09

07 Nov '09

Hi all, The following minimal example used to work with mkiv (until last May, I would guess…) but now it doesn't work with the latest ConTeXt version 2009.09.21 17:39 Can any one tell me please what am I doing wrong? Best regards: OK %% begin \setupcolors[state=start] \starttext \startbuffer[axes-1] numeric u ; u := .5cm ; path xox ; xox := (-u,0)--(8u,0) ; path yoy ; yoy := (0,-u)--(0,7u) ; draw xox withcolor blue ; draw yoy withcolor blue ; \stopbuffer This MetaPost graphic is \doifmodeelse{mkiv}{not shown with mkiv} {shown with mkii}: \placefigure[middle][-]{}{\processMPbuffer[axes-1]} {} \stoptext %% end

\overrightarrow not working in mathmode in Metapost?
by Matthijs Kooijman 30 Oct '09

30 Oct '09

Hi, I've been trying to use the \overrightarrow command within a metapost graphic, but it doesn't work. Math mode does work, for example \vec works like expected. Outside of metapost, \overrightarrow works as expected. To illustrate the problem, I've created the following simple testcase: \starttext \startMPcode draw btex $\vec{foo}$ etex; draw btex $\overrightarrow{foo}$ etex; \stopMPcode \stoptext This gives the following error output: ! Undefined control sequence. \dodosmash [#1]->\edef \@@smash {#1}\futurelet \nexttoken \dododosmash \relbar ->\mathrel {\smash -} \mtharrowfill ...inmuskip \thickmuskip \relax #8#5 \mkern -#1mu \cleaders \hb... \dodohandlemathoverarrow ...{\ialign {##\crcr #2#3 \crcr \noalign {\kern #1\n... \mathpalette ...>\mathchoice {#1\displaystyle {#2} }{#1\textstyle {#2}}{#1\sc... <argument> ...ex; draw btex $\overrightarrow {foo} $ etex; ... l.5 \stopMPcode It seems the \overrightarrow command uses \@@smash, which isn't defined when running from metapost? Is this expected? Is this a bug? Gr. Matthijs

Math symbols "rigt floor" and "left floor"
by Thomas A. Schmitz 29 Oct '09

29 Oct '09

Hi all, quick question: does anyone know of a free font that contains the symbols "left floor" (uni230A) and "right floor" (uni120B)? I have a commercial font that does have them, but I need a portable and free version for the next release of my Greek module. Thanks, and all best Thomas

Simple Newbie Question.
by Stirling Westrup 25 Oct '09

25 Oct '09

I'm hoping the answer to this question should be obvious, but I'm having no luck with it. I'm trying to do a layout for a 1-page datasheet. At the very bottom of the page, in some tiny font, I need to put a copyright notice and datasheet ID number. Ideally I'd like to define some fixed text block containing the text (as its exact size and font have not yet been finalized), and then somehow define the height of the footer to be exactly equal to the height of the text block. Once I've done that, I need to place the text in the footer. I've been going back and forth through the scattered bits of ConTeXt manual and the wiki, but I'm having no luck in figuring out how one might do this. -- Stirling Westrup Programmer, Entrepreneur. https://www.linkedin.com/e/fpf/77228 http://www.linkedin.com/in/swestrup http://technaut.livejournal.com

virtual fonts in luatex?
by Thomas A. Schmitz 15 Oct '09

15 Oct '09

Hi all, I'm running into a problem, but maybe not all hope is lost. For my Greek stuff, I will sometimes need a "dotbelowcomb" accent. Only very few fonts have that, but no problem, in mkiv, I can simply take that from a follback font: \definefontfallback [GreekFallback] [name:texgyretermesregular] [0x0323] [force=no,check=no] Now I would like to remap the exclam character to this dotbelowcom. Again, no problem: with a fea file, I can write a sub rule sub exclam by dotbelowcomb but I can't combine both approaches: if the font doesn't have the character, I get an error about "invalid glyph index." In good old pdftex, it was possible to define a virtual font for such occasions, and I seem to remember that there's something similar in mkiv, but I'm unsure how it can be done. Any pointers? Thanks, and all best Thomas

Hi Hans, there's a problem with today's beta: at every run I get this error: Attempt to allocate memory failed. fontnames | identifying tree font files with suffix otfMTXrun | fatal error, no return code, message: luatex: execution interrupted even when I call something like this: mtxrun --script fonts --list --pattern="times*" MTXrun | fontnames: identifying tree font files with suffix otf Attempt to allocate memory failed. zsh: abort mtxrun --script fonts --list --pattern="times*" This is on OS X intel, if this matters.

framedtext in naturaltables
by Xan 02 Oct '09

02 Oct '09

Hi, If I put \startframedtext[frame=off,background=screen,width=broad]....\stopframedtext in naturaltable, then I get that framed text passes table and that it aligns at top. Can you say me please how to get a right behaviour? An example: \placefigure [here,none] [fig:taula-roques-i-minerals] {Característiques de roques i minerals} {\bTABLE[frame=off,align=middle] \setupTABLE[1,2][1][leftframe=off,rightframe=off] \setupTABLE[r][2][topframe=on,bottomframe=on] \setupTABLE[c][1][rightframe=on] \setupTABLE[c][2][leftframe=on] \bTR[align=middle] \bTD[align=middle] {\sc {\blue{Minerals}}} \eTD \bTD[align=middle] {\sc {\blue{Roques}}} \eTD \eTR \bTR[align=middle] \bTD[align=middle,nc=2] {\sc Composició}: Les roques i els minerals estan formats per {\em \bf matèria inorgànica}, que és diferent de la matèria que compon els éssers vius \eTD \eTR \bTR[align=middle] \bTD {\sc Definició}: Els minerals són materials terrestres que formen les roques.

utf-8 math and xetex
by Aditya Mahajan 01 Oct '09

Hi, Utf-8 math input that works with pdftex (α, β, etc) does not work with xetex. Is this by design, or a recent bug? Minimal example \enableregime[utf-8] \starttext $α β$ \stoptext Thanks, Aditya
