transparency problem (mkiv)
by Peter Rolf 05 Sep '11

05 Sep '11

Hi, I noticed some problems with transparency colors lately. But every time I tried to make a minimal example out of it, the code worked. Now, by chance, I found a not working example. \setuppagenumber[state=stop] \definecolor[tcolor][r=1,a=1,t=.6] \definetextbackground[ghost] [background=color,backgroundcolor=tcolor] \starttext \starttextbackground[ghost] FOO \stoptextbackground \stoptext Here the error message... metapost > terminal: >> (redpart boxfillcolor,greenpart boxfillcolor,bluepart boxfillcolor) >> 1 ! Equation cannot be performed (color=numeric). <to be read again> withprescript transparent->1withprescript "tr_alternative="&decimal.transparency_alternativ... <*> ... boxfillcolor := transparent(1,0.6,(1,0,0)) ; boxfilloffset := 0.0pt ... ! Extra tokens will be flushed. Regards, Peter

Exported figures
by Aditya Mahajan 05 Sep '11

05 Sep '11

Hi Hans, Two bugs in figure export: 1. If one uses images without extension, then the generated \jobname-images.css file does not contain any extensions; so no figures are shown in the output. One possible fix is to change \dotagfigure in back-ini.mkiv to \appendtoks % we can have differently scaled images \def\dotagfigure{\taggedctxcommand{settagfigure(,"\figurefullname","\figurefilepage",\number\dimexpr\figurewidth,\number\dimexpr\figureheight)}}% \to \everyenableelements % \figurefullname instead of \figurefileoriginal 2. What is the best way to handle multipage pdf images? I frequently create a big pdf with many images and then use \externalfigure[...][page=2] I don't know if svg has support for multiple pages or not. Aditya~

ConTeXt mode in emacs: disabling raising of superscripts?
by Alasdair McAndrew 05 Sep '11

05 Sep '11

I hope my subject line says it all: if I type, say $x^2$ in an emacs buffer, with ConTeXt-mode, the "2" is automatically raised. This to me looks ugly. I've been searching through the emacs customization options but haven't yet found what I need. And I don't want subscripts lowered either. Any ideas? Thanks in advance! cheers, Alasdair -- Blog: http://amca01.wordpress.com Web: http://bit.ly/Alasdair Facebook: http://www.facebook.com/alasdair.mcandrew

Hi, I get no strut in \framed when using 'offset=overlay' or 'offset=none'. \setupcolors[state=start] \starttext \showstruts \framed[offset=1pt]{abc} % ok \framed[offset=overlay]{abc} \framed[offset=none]{abc} \stoptext Same for both marks. mtx-context | current version: 2011.08.27 13:24 This is LuaTeX, Version beta-0.70.1-2011051907 (rev 4277) pdfTeX 3.1415926-1.40.11-2.2 (Web2C 2010) Regards, Peter

Bug in links in the list of splitted tables (standalone ver. only)?
by Jaroslav Hajtmar 04 Sep '11

04 Sep '11

Hello ConTeXist... I found a problem in functioning links in the final PDF document created in standalone MkIV. 1. When I create in standalone MkIV version more of splitted tables, then links in the list of tables are broken (numbering is fine, but when you click on an active link then does not work). 2. When I compile the source file by MkIV part of TeX live 2010 (ConTeXt ver: 2010.05.24 13:05 MKIV fmt: 2010.9.21) then numbering in the list of tables is broken (each of partitioned tables has a separate number) but links are OK. 3. When I compile the source file by MkII part of TeX live 2010 (ConTeXt ver: 2011.07.26 09:17 MKII fmt: 2011.7.26) then everything is fine. Is it a bug or I something wrong? Thanx Jaroslav Hajtmar Here is my minimal example: \setupcolors[state=start] \setupinteraction[state=start,color=blue] \def\parenttable{{\bTABLE\dorecurse{60}{\bTR\dorecurse{3}{\bTD x\eTD}\eTR}\eTABLE}} \starttext List of tables \placelistoftables \page \placetable[split][tab.1]{Table 1}{\parenttable} \page \placetable[split][tab.2]{Table 2}{\parenttable} \page \placetable[split][tab.3]{Table 3}{\parenttable} \stoptext

TikZ: \@flushglue undefined
by Philipp A. 04 Sep '11

04 Sep '11

i don’t know if it’s a TikZ or a ConTeXt bug, but with the newest mkiv beta installed with mtx-update.lua, tikz fails when using the option “text badly centered” in combination with “text width”: \usemodule[tikz] \starttext \tikz\node[text badly centered, text width=1cm]{fail}; \stoptext gives: \tikz@text@action ...p =0pt\rightskip \@flushglue \leftskip \@flushglue \relax ... as it doesn’t occur with LaTeX, i think it might be a ConteXt bug.

Calligraphic math alphabet with xits
by Aditya Mahajan 04 Sep '11

04 Sep '11

Hi, There are two calligraphic shapes in math, calligraphic (e.g., \cal) and script (e.g., \scr from RSFS). The default shape of \cal with xits is more like RSFS \scr than \cal. Does xits also have a less stylistic variant for calligraphic letters? If so, how can I select that? Aditya

How to properly handle synonyms in \getparameters?
by Mojca Miklavec 03 Sep '11

03 Sep '11

Dear gurus, This question concerns both MKII and MKIV (I need the functionality in both, even though I will try to rewrite the MKIV part as soon as I have time). I have a command: \mycommand[a][newparam=value] with more or less the following definition: \def\mycommand[#1][#2]{% \getparameters[@@mycommand@#1@][#2] % ... some extra code ... } However I used to use \mycommand[a][oldparam=value] and now I would like to switch the syntax to \mycommand[a][newparam=value] but I would like the oldparam to keep working normally. I will read the value with \@@mycommand@a@newparam. My question: what is the most elegant value to do that? I can imagine something like \def\mycommand[#1][#2]{% \undefinecommand\@@mycommand@a@oldparam % pseudocode \getparameters[@@mycommand@#1@][#2] \doifdefined{\@@mycommand@a@oldparam} \let\@@mycommand@a@newparam\@@mycommand@a@oldparam % ... some extra code ... } but there is most probably some more elegant solution to that? Thank you, Mojca

Colored text in \type?
by Alasdair McAndrew 02 Sep '11

02 Sep '11

I'm writing up some computer notes for my students, and I have examples of variables and other commands which involve characters like % and underscore. These are typeset with \type{%t^y_8*&} for example. What I would like to do is to color these as well. However \color[blue]{\type{%t^y_8*&}} doesn't seem to work; nor does {\blue \type{%t^y_8*&}} So - how do I obtain colored text within \type?
