No cmyk support in MKIV (TexLive 2012 version)?
by Bill Meahan 10 Sep '12

10 Sep '12

Trying to define some spot colors using the wiki examples. I get the following error message every time I run MKIV: colors > cmyk color space is not supported Here's the relevant section of my environment file: % Turn on colors. \setupcolors[rgb=no,cmyk=yes,spot=yes,state=start,overprint=yes] %\setupcolors[state=start] % Define the colors we want to use and give a print shop Pantone % equivalents to work with, % set up the cmyk fallbacks \definecolor [PantoneTwoNineFour] [c=1,m=.68,y=7,k=.28] \definecolor [PantoneThreeZeroZero] [c=1,m=.42,y=0,k=0] % Define tints of spot colors to be used in document for coloring text \definespotcolor [DarkBlue] [PantoneTwoNineFour] [p=1,e=PANTONE 294 PC] \definespotcolor [LightBlue] [PantoneThreeZeroZero] [p=1,e=PANTONE 300 PC] I do get the "DarkBlue" in my pdf output but no sign of the "LightBlue" anywhere. -- Bill Meahan Westland, Michigan USA

Search path.
by Andre Caldas 10 Sep '12

10 Sep '12

Hello, list! I am really new to ConTeXt. I am writing a book http://topologia-geral.ourproject.org/ It is written in LaTeX and I intend to migrate it to ConTeXt. I want to migrate and I want to be as far from HACKS as I can. So I want to know the recommended way to do things. One of my first difficulties comes from the "search path" used by texexec. It seems to me that the path searched for components, products and environments depends on the path were the script was called from. That is, it depends on the "current working directory". My question (honestly) is: - Why would I want this behavior? When I write a project, product, component or environment file, why would I want the references I made to be dependent on the directory where the script was called? Shouldn't things be like the #include "relative_path.h" used in the C language, for example? That is, shouldn't those paths be relative to the script that refers to them? Am I missing something?

Luatex crash with x86-64 Linux binary
by Brian R. Landy 10 Sep '12

10 Sep '12

Hi, I am running the latest minimals on a 64bit Linux system and ran into a luatex crash with a specific file. I reduced the file down to a simpler version that still triggers the crash, and thought it would be of some interest to post (the resulting pdf, if generated, will be ugly since I removed a lot of formatting, and some of the code in the file may appear extraneous). I am running: $ context --version mtx-context | ConTeXt Process Management 0.60 mtx-context | current version: 2012.09.06 23:03 $ luatex --version This is LuaTeX, Version beta-0.70.2-2012052410 (TeX Live 2012) What I think makes this interesting is the same file does not crash on three other setups I tested: - 32bit OS X (beta-0.70.2-2012052310) - 64bit OS X (beta-0.70.2-2012052309) - the same Linux system, but I replaced the 64bit Linux luatex binary with the 32bit Linux binary (beta-0.70.1-2012052416 (rev 4277), I see this is an older version but I downloaded directly from the minimals site today). It rebuilt caches and processed the file successfully. I updated minimals on both OS X systems today so all three systems should be otherwise identically configured. Various alterations to the file can avoid the crash; a few I found are---adding a \strut before the word jumbo, removing the nested bTABLE (this appears to be unneeded in the attached example), removing the \definefontfeature statement at the top of the file. Anyway I'd be interested to know if anyone else sees the same issue. I'm sure this is a real edge case error but hope it is helpful to track down the problem. Please let me know if there is any other debugging info you would like to see from my end. Thanks, Brian

Problem with *lettrine* module in Mk-iv
by Francisco Gracia 10 Sep '12

10 Sep '12

I am making my first steps in ConTeXt. I am only interested in Mk-iv and am using version 2012.09.06 23:03. I tried to explore the possibilities of the additional module *lettrine* following its documentation (*lettrine-doc.pdf*) and prepared the following example, which reproduces almost exactly the first one found in that text: \usemodule[lettrine] \starttext \lettrine {T}{he two} typeset arguments are the dropped capital and the run-in text following it; the \TeX\ source of this paragraph started with \starttyping "\usemodule[lettrine] \starttext \lettrine{T}{he two} …" \stoptyping … \stoptext When I typeset it with ConTeXt, the result was not what the documentation showed. The initial capital was fine and so was the rest of the first line, but the second line was blank and the regular text continued at the third and following lines. This was with the default value of 2 lines as size for the capital. If one indicates a greater number of lines, all of them but the first one are blank and the regular text continues after all that whitespace. As I was not completely sure that my installation of ConTeXt was unobjectable, I tried to typeset the example in *ConTeXt online* (http://live.contextgarden.net/) There the option to use *LuaTex / Mark-iv* is not offered (!!??), so I selected the *pdfTex* alternative and then it happened that everything behaved as expected (at least in the first part of the example, as some of the following commands seem not to be understood by *pdfTex*). My conclusion is that *lettrine* does not work correctly with Mark-iv and there is somewhere a bug that has to be corrected. But I could be mistaken. Am I doing something wrongly? Thanks for your interest

pre-stepwise / current
by Daniel Schopper 10 Sep '12

10 Sep '12

dear all, I’m trying to build a stepwise presentation, but the following minimal example (got it from the ML[1]) produces an error: ConTeXt ver: 2012.09.06 23:03 MKIV fmt: 2012.9.9 … !LuaTeX error: There should have been a lua <node> here, not an object with type string! The example compiles with standalone 2012.06.13 while it is broken from 2012.07.27 onwards. Is the stepper-module no longer supported? TIA, Daniel \usemodule[pre-stepwise] \setupinteraction[state=start,click=off] \setupbodyfont[palatino] \starttext \StartSteps \starttabulate \NC test \FlushStep \NC test \FlushStep \NC \NR \NC test \FlushStep \NC test \FlushStep \NC \NR \NC test \FlushStep \NC test \FlushStep \NC \NR \stoptabulate \StopSteps \stoptext [1] http://www.mail-archive.com/ntg-context@ntg.nl/msg55196.html

Sequence of MetaPost Pages
by Troy Henderson 09 Sep '12

09 Sep '12

When I create animations using MetaPost, I typically do something like for n=1 upto N: beginfig(n); <some code> endfig; endfor; and a sequence of figures are created. How can I do this in ConTeXt using \startMPpage ... \stopMPpage? Troy Henderson

3D annotations problems
by Michail Vidiassov 09 Sep '12

09 Sep '12

Dear Hans and All, the examples from back-u3d.mkiv fail to work with latest beta (rectangled "undefined" message appears instead of annotation), but if "\textwidth" is replaced by "in" in the tex file 3D annotations appear OK. Is that a bug, a feature or some transitional state of ConTeXt (case when things are known to be broken something else is under reform). Sincerely, Michail

Working with variables in MkIV (\ setvariables, \getparameters etc)
by Jaroslav Hajtmar 09 Sep '12

09 Sep '12

Hello ConTeXist, Is it possible go through all the keys of \setvariables (getvariable) macro and create the appropriate macros, as in the case of \getparameters macro? I mean macro like \getallvariablesfrom[myfirstnamespace], which return contents of brackets macro \setvariables[myfirstnamespace] (it mean list of all assignments key=value ...) In addition, you can assign all the variables one namespace to another namespace (or to create a loop which all variables passed and placed into the other namespace.)? Thanx Jaroslav Hajtmar Here is my inspiration of example : \setvariables[myfirstnamespace][id=1, value={text}] \starttext % \getparameters[myfirstnamespace][\getallvariablesfrom[myfirstnamespace]] % Now would be defined macros \myfirstnamespaceid (1) and \myfirstnamespacevalue (text) % Assign all the variables of [myfirstnamespace] namespace to [myotherspace] namespace? %\setvariable[myotherspace][\getallvariablesfrom[myfirstnamespace]] \stoptext

Promotion of the ConTeXt IRC channel
by Marco Patzer 08 Sep '12

08 Sep '12

Hi, I was wandering if we should promote the ConTeXt IRC channel on the contextgarden home page, e.g. underneath “Welcome to ConTeXt garden” or “External Help”. The current page (http://wiki.contextgarden.net/IRC) is unlikely to be found by anyone. I think most questions should stay on the mailing list, since I consider the mailing list almost as “the second ConTeXt manual” and it can easily be searched, in contrast to IRC. At the moment the channel is dead, which is probably due to the fact that no one knows of its existence. But it might turn into a valuable source of information, e.g. regarding installation problems for which the mailing list might not be as suitable. Marco
