ConTeXt colours in TikZ
by Marco 18 May '12

18 May '12

Hi everybody, I don't get context colours working in tikz. There were several issues on the mailing list in the past and the solution always seems to be some kind of hack. But none of the hacks work (with a current context). Example: \usemodule [tikz] \definecolor [darkblue] [b=.2] \starttext \starttikzpicture % works \fill [blue] (0,0) circle(1); % fails % \fill [darkblue] (0,0) circle(1); \stoptikzpicture \stoptext I get the following error: Runaway argument? 0 0 0.2 rg 0 0 0.2 RG\pgf@stop {darkblue}\else \edef \pgf@marshal {\noexpand \ETC. ! File ended while scanning use of \pgfutil@context@parse@gray. system > tex > error on line 0 in file : File ended while scanning use of \pgfutil@conte xt@parse@gray ... <empty file> <inserted text> \par Marco

Most portable font name
by Philipp Gesang 18 May '12

18 May '12

Hi all, tl;dr: by which name to refer to a font. I was about to recommend (tomorrow; context: an introductory LaTeX course) *the* way of referring to a font by its name. As we all know, the same font (as in file) usually comes with a variety of possible denominations. “otfinfo -i” on a *file name* results in a list of *full name*, *Postscript name*, *unique id*, etc., which all might have some valid purpose. I have come across answers to assignments that made me wonder “How on earth did E get that to work on Eir system?”. There’s some background info [1] on the Fontforge pages but it doesn’t really answer my question: Which identifier is least likely to break things and at the same time most portable between both frontends (Fontspec, Simplefonts, typescripts) and platforms (Win/Linux/Mac)? For some time now I myself settled for the Postscript name as it never caused problems in typescripts and it’s got no spaces. The filename might be the most explicit one, but oftentimes contains spaces which I *always* replace with underscores prior to installing a font; also case insensitive filesystems might cause trouble. Also, some fonts have weird file naming schemes (e.g. CMU and the Paratype fonts), so extra comments may be required to support legibility of the resulting code. The typescripts that come with Context use both (“name:” and “file:”) but I have no clue why exactly which method was chosen over the other in what case. The fontspec documentation (and the Simplefonts module and our course so far) conforms to the WYSIWYG tradition of purportedly more human-readable, spaced identifiers, e.g. “TeX Gyre Bonum Bold”. (Cf. [1]: “FullName is designed to be read by humans”.) So I judged that my preferred choice might not be as good as I think. I got cold feet and am about to remove the slide where I recommend the PS name (I can do that later anyways). Is there -- apart from personal opinions -- some valid reason to prefer one name over the other *in general*? Thanks for any advice and opinions.

Lists and alternative=command

Testing TeX Live 2012
by Mojca Miklavec 17 May '12

17 May '12

Dear ConTeXt users, TeX Live 2012 is going to be released soon. After the first successful year of ConTeXt in TeX Live, it would be great to get enough testers before the release (to make sure that it works flawlessly) and to get rid of as many bugs as possible. See http://tug.org/texlive/pretest.html for links and instructions. You could try wget http://ctan.ijs.si/mirror/tlpretest/install-tl-unx.tar.gz tar xvzf install-tl-unx.tar.gz cd install-tl-<every-day-a-different-name> ./install-tl -gui -repository http://ctan.ijs.si/mirror/tlpretest and install a ConTeXt scheme for example. (Alternatively you can first fetch all the packages to local disk.) Then just add the binary path to your PATH and feel free to play. Mac users can also try MacTeX 2012 from tlpretest (with some extra care), but you first need to update to get the latest ConTeXt. Mojca (The version of ConTeXt is the same as latest beta, so any bugs fixed in beta can just as well proliferate to TeX Live.)

Local modules not found

17 May '12

Hi, I upgraded to the latest beta from the 2011 stable version for the first time. Now my local modules are not found. Having searched the wiki and the mailing list, I can find no help. Any ideas? Error messages: \usemodule[homework-fmt] --> resolvers > modules > not found: 'homework-fmt' \input homework-fmt --> ! I can't find file `homework-fmt'. Here is a snippet from "context --generate" that might indicate the problem (/Users/mike/Library/texmf contains my tex modules : resolvers | methods | resolver: method=generators, how=uri, scheme=file, argument=/Users/mike/Library/texmf resolvers | expansions | scanning path '/Users/mike/Library/texmf', branch '/Users/mike/Library/texmf' resolvers | expansions | 266 files found on 20 directories with 58 uppercase remappings resolvers | resolving | resolvers | resolving | not saving runtime tree '/Users/mike/Library/texmf' Thanks! Michael [Background: I started learning ConTeXt last winter using the 2011 TeXLive version and TeXShop (I've a Mac). Now the semester is over, I'm trying to update to a more recent ConTeXt. First I got TeXLive 2012 pre-release, but TeXShop still used last year's ConTeXt. So I followed the wiki instructions for getting the latest beta. Eventually I found a directory name was different and now TeXShop uses the latest beta. The latest beta is in a separate directory tree from TeXLive, which I set up 6 months ago or so from instructions on the wiki for running Mark IV.] ________________________________ This e-mail message (including any attachments) is for the sole use of the intended recipient(s) and may contain confidential and privileged information.

\setupbodyfont restricted to pt as unit

Hi!

xtable question

I have the following xmlsetup for a tablecell in xtable (plus other appropiate definitions): \startxmlsetups xmlcommon:td \startxcell[\doifnot{\xmlatt{#1}{width}}{\empty}{width={\xmlatt{#1}{width}}},] \xmlflush{#1} \stopxcell \stopxmlsetups and the following table: <table> <tr> <td> One </td> <td width="8cm"> Two </td> </tr> <tr> <td> <b>Three</b> </td> <td width="8cm"> Four </td> </tr> </table> Why isn't the width setting on the cells not honoured and is the following message appearing in the log: check > missing or ungrouped '=' after '\doifnot {8cm}{}{width={8cm}}' Also I tried \expanded{startxcell..} but it made no difference. Neither does width={\xmlatt{#1}{width}} because the a broad setting results instead of a cell 8cm wide. How can I then accomplish the following parameter scheme? on <td width="dimension"> the \startcellx[ takes width=dimension, on <td> the \startcellx does not take a width-paarameter.

I can see \setuptables[height= width= depth=] but that does not take dimensions (error Illegal unit). What it does with the numbers given is not clear to me, because the ConTeXtGarden has no explanation of its effect.

Hi again, seems like it’s impossible to setup the level for combined lists anymore. (MkIV, latest beta). While \placelist[part,chapter] works, I didn’t find a way to \setupcombinedlist[content] just down to chapter level, not deeper. The "level" key is gone in MkIV, and "part,chapter" in the setup command don’t do anything.

fixing mpiv on installation path with spaces
by Mojca Miklavec 16 May '12

16 May '12

Hello, last year Taco added many patches to make sure that ConTeXt works even when installed to "C:\Documents and Settings\ ..." and other weird paths with spaces. However metapost in mkiv still fails. I figured out that the following patch (which *won't* handle paths with quotation marks properly) in mlib-run.lua fixes the problem: local preamble = [[ boolean mplib ; mplib := true ; let dump = endinput ; - input %s ; + input "%s" ; ]] but I'm not sure if there are any other side effects or if there are other places that also need a patch. I didn't test with filenames with spaces or with filenames with weird characters that need escaping. Maybe it would be helpful to pass file.addsuffix(name,"mp") through additional filter (instead of simply adding quotation marks) that would also check if any other character needs escaping and add quotation marks if needed. Minimal example: - install ConTeXt into path with spaces - test with context on \starttext \startMPcode draw fullcircle scaled 3cm; \stopMPcode \stoptext I would be grateful if somebody could take a look, so that a fix could make it into TL 2012. Thanks, Mojca

Insertion of a Document I.D.

I want to generate a document i.d. from the .tex source filename and the current date and put it into the footer. This might be possible already, but I could find it by searching the wiki for filename and document it, or rather too much since filename is mainly used for command line parameters, etc. I know the \currentdate will give the current system date part that I can use, but is there any \filename type command for the master filename, so that a document i.d. could be generated automatically. e.g. \filename\currentdate Regards

"Typescripts for Dummies"
by Bill Meahan 15 May '12

15 May '12

Is there a document anywhere that would be the equivalent of "Typescripts for Dummies?" (as if such a book really existed) I am trying to write some typescripts for the Venturis ADF and Beneris ADF families (and a few others) using Wolfgang's typescripts for Fontin et. al. as a guide. I can't seem to figure out what, "\s!" or "\typescripttwo" of "\typescriptthree" do and the examples I have looked at on the wiki either don't contain them or don't explain them . I also don't seem to be able to find a command reference for \starttypescript which explains what the various option fields mean or what "predefined" values exist for each.

atpage || number comparing
by Peter Schorsch 15 May '12

15 May '12

Hi, it tried to do a \atpage command that results a) some page => nothing b) different page => pagenumber with some text (e.g. "auf Seite XY") \def\atPage[#1]% {\doifnot{\at[#1]}{\currentpage}% {\at[#1]}% } My problem with this is, that the \doifnot always results as not equal; it is like the types mismatch as if I exchange \at[#1] with a pure number the comparing works. If so, how can the types be corrected? Additionally - if possible - I would like to add case that the referred page is on the other page but in duplex mode adjacent to the actual page. Is that possible to do this? I unluckily dont know how to make working simple calculation in tex code. To be complete I found in the file strc-ref.mkiv some notes about a planed \atpage command: %D A still very rudimentary|/|experimental forward|/|backward %D reference mechanism is provided by the macro \type{\atpage}: %D %D \starttyping %D ... \somewhere{backward text}{forward text}[someref] ... %D ... \atpage[someref] ... %D \stoptyping %D %D In future versions there will be more sophisticated % 0 = no page reference % 1 = same page % 2 = preceding page % 3 = following page % 4 = backward, same page (todo) % 5 = forward, same page (todo) But that level of the ambient tex is still out of my scope.

Specifying leading?
by Bill Meahan 15 May '12

15 May '12

How does one specify leading in ConTeXt? In traditional typography, it is common to specify the type size and leading to indicate the inter-line spacing of a block of text. Setting type "solid" means to use no spacing between lines - not usually a good idea ;-) More often, good typography requires a minimum of two points of leading between adjacent lines and might be specified as 12/14 or 12/15 meaning to set twelve-point type on a fourteen or fifteen point "leading" resulting in inter-line spacing of two and three points respectively. Is there an easy way to specify this in ConTeXt or must I muck about with baseline skip? I have tried looking this up on the wiki and in the font documentation but it either is not there or is worded in such a way I am not recognizing it.

Hi, I am trying to pass a tex color as a paramter to a module. I used the example from the wiki as a base. But as soon I hand over a color directly it does not work. Any help is welcome as I am looking forward to hand in my first module. Are there any rules how and where to hand in a module for context? Thanks P. --8<---Modul: bgcolor.tex--------------- \startmodule[bgcolor] \unprotect \definecolor[grau][s=.35] \setupmodule[color=grau] \setupbackgrounds[page][background=color,backgroundcolor=\currentmoduleparameter{color}] \protect \stopmodule \endinput --8<--tex file itself--------- \setupcolors[state=start] \definecolor[bordeaux][r=.66] \usemodule[bgcolor][color=bordeaux] \starttext Hello world! \stoptext

hvdm-exm module fails
by Martin 14 May '12

14 May '12

Hi, I am trying to make use of the "hvdm-exm" module for a series of tests and that fails. Below is the basic code I am using. As I could not find a usage sample, I might have it wrong. It fails with \startexam as "undefined" and an internal message that it seems to have a language problem (WARNING ? unknown -- current language en tried). Looking into the file hvdm-exm.tex I can find the source of the error message, but it's beyond me to really understand what's going on. My ConTeXt is updated as of today (30.4.2012). I updated the core file "hvdm-exm.tex" to the 2010-11-17 version but that has no obvious influence. Also checked permissions (just to be sure, folders 755, files 644) and fixed them with no impact. Afterall, the files are all loaded. http://archive.contextgarden.net/message/20101212.154453.528d5fd7.en.html Help would be much appreciated.

Did usage of \expanded changed?
by Peter Schorsch 11 May '12

11 May '12

Hi, I "reactivated" some code that was working a year ago. But now it seems that \expanded has no effect in my case (see below). I also tried it with \normalexpanded and \expandedafter but both had also no effect. My problem seems to be this line of the full example below: \doifsomething\Paragraphmark{\expanded{\textreference[\Paragraphmark]{\fullheadnumber/\rawnumber[ParagraphNumber]}}}% The error shows itself in the line: Should be 1/1: \in[test] As \in[test] gives me 1/3 instead of 1/1. (1 was the number assigned to the first paragraph - 3 is the acutal number). Can someone tell me what I need to change?

Strange crash when using lxp library
by Procházka Lukáš Ing. - Pontex s. r. o. 11 May '12

Hello, I have a strange problem. I tried to prepare the simplest example. Let's have a table utility in 'Table-U_.lua' (to be placed to LUA_PATH): ---- table.fromExcelXML = function(fn) ... tabs[true] = true -- Comment this line to make it work(?!) [1] ... end if not context then require "lxp" print("\n777777") table.fromExcelXML("InzSiteLitom_Nove.xml") print("\n888888") end ---- When you call it from the command line, it works fine: ---- C:\Lukas\ConTeXt\TestDDv>lua -e require'table-u_' 777777 888888 ---- When used in a context file: ---- \mainlanguage[cz] \enableregime[cp1250] \startluacode require "lxp" require "Table-U_" print("\n111111") table.fromExcelXML("InzSiteLitom_Nove.xml") print("\n222222") \stopluacode \starttext AAA \stoptext ---- it crashes with an exception in luatex: " Exception "unknown software exception" 0xc000000d" at 0x1028e4c3. ... " Would anyone have an idea what causes the program crash? I also observed that commenting a line [1] in the "Table-U_.lua" makes context work; but the place seems "innocent", so I have no idea what can cause ctx crashing. Could anyone test the code, respectively give a hint how to make the [simplified] code work? All ideas are welcome. Thank you in advance. Best regards, Lukas -- Ing.

bug? margens with duplex
by Peter Schorsch 11 May '12

11 May '12

Hi, I am using \ininner and \inouter to set text into the margins. As soon I also use duplex the margins are messed up at every second page. Unluckily the [stack=continue] option does not help. I put an example incl. pictures of the results on my user talk page on the wiki: http://wiki.contextgarden.net/User_talk:Tralalas That way my problem might be easier to understand. Any help is welcome as this problem became a major issue for me. Thanks P.

Is it time to update context? From the date of the wiki revision it seems not, since I am on ConTeXt ver: 2011.11.29 23:11 MKIV FWIW, I cannot find the intermediate file 'm_k_i_v_ChangingField_ILUC.pdf' on my disk either…both graphics files are in the same location, both exist, both are named correctly….

"standard" for bibliographies
by Mojca Miklavec 10 May '12

10 May '12

There used to be discussions about some "common standard" for storing bibliographies. I'm testing http://www.mendeley.com/ and would like to export to ConTeXt-friendly database (bibtex export is supported). It seems that for that one would have to use http://citationstyles.org/ so I will try to figure out if "The Citation Style Language" can be used to export data to what is currently required by ConTeXt. But if you are thinking about xml-based format for the future, it might be worth taking a look at the second website. Mojca

Mkiv is moving quite fast, so if you really need to use mkiv, this is way too old. Be warned though: things have changed pretty dramatically over the past 6 months or so, so if this is for something with a tight deadline, I wouldn't just simply update.

japanese spaced
by Steffen Wolfrum 10 May '12

10 May '12

Hi, if a paragraph is set to align=block the space between words can be stretched. If eg. a japanese word is mentioned in such a paragraph the space between the japanes characters gets spaced/stretched too (see example attached). This may be right for japanese texts, but it is wrong if the main/surrounding language is not japanese (and thus no additional space between characters is wanted). What is an easy way to avoid this? \definestartstop [Japaned] [commands={\language[jp]\DoNotSpace}]?? Steffen -------

Font for MetaPost graphics
by Marco 10 May '12

10 May '12

The wiki claims setting up an MPenvironment is enough to change the font in MetaPost graphics: \startMPenvironment%[global] \switchtobodyfont [sans] \stopMPenvironment \starttext This should be serif. \startMPcode draw textext("This should be in sans."); \stopMPcode \stoptext However, this has no effect. All text is in default serif font. If [global] is provided, all text is in sans font. I am aware of a similar issue in a thread last year¹, but the solution didn't really address the problem. textext("\sans This should be sans.") works here, but the point is that the MPenvironment fails. Why is that? Marco [1] http://thread.gmane.org/gmane.comp.tex.context/69044

switching to a different math font (with alternatives) in the middle of document
by Mojca Miklavec 10 May '12

10 May '12

Hello, I'm just wonderding if there is a way to switch to an OpenType Math font (referred to by name or filename, without any predefined typescript) with some stylistic alternative in the middle of the document, like in the LaTeX example: running text ... \setmathfont[Scale=0.86,StylisticSet=4]{Lucida Bright Math OT} $\mathcal{ABC XYZ}$~(StylisticSet=4) ... running text ... \setmathfont{Asana Math} $\mathfrak{ABC XYZ\,abc xyz}$ or do I always need to provide a predefined typescript? How does one switch between stylistic alternatives for math? I have a problem with {\switchtobodyfont[asana] $\mathscript ABC XYZ\,abc xyz$} and I also need to figure out how to get "math bold italic sans serif greek alphabet". Any hints welcome. Thank you, Mojca

Hello, I'm a new user of context (and of this mailing list). I'm facing some problems in splitting the \startalign ... \stopalign content on more pages. This is the formulas: \setupformulas[align=right] \startformula \startalign[n=3, align={left, right, left}] \NC \text{dove} \quad \NC Y \NC = min \left({{e_{yfitest}} \over {R_{fi}}}; 0.04 \right) = min \left({{\sbc{e_yfitest}} \over {\sba{R_fi}}}; 0.04 \right) =\sbd{Y} \NR \NC \NC Z \NC = log_{10} \left({1 \over Y} \right) = log_{10} \left({1 \over \sbd{Y}} \right) = \sbc{Z} \NR \NC \NC X \NC = {{r_{fi}} \over {D_{ifi}}} = {{\sba{r_fi}} \over {\sba {D_ifi}}} = \sbd{X} \NR \NC \NC N \NC = 1.006 - {1 \over {6.2 + \left(90 \cdot Y \right)^4}} = 1.006 - {1 \over {6.2 + \left(90 \cdot \sbd{Y} \right)^4}} = \sbd{N} \NR \startluacode if X==0.06 then tex.print("\\NC \\NC \\beta_{0.06} \\NC = N \\cdot \\left(-0.3635 \\cdot Z^3 + 2.2124 \\cdot Z^2 - 3.2937 \\cdot Z + 1.8873 \\right) = \\NR") tex.print("\\NC \\NC \\NC = N \\cdot \\left(-0.3635 \\cdot \\sbc{Z}^3 + 2.2124 \\cdot \\sbc{Z}^2 - 3.2937 \\cdot \\sbc{Z} + 1.8873 \\right) = \\sbc {beta006} \\NR") tex.print("\\NC \\NC \\beta \\NC =\\beta_{0.06}=\\sbc{beta006} \\NR") elseif X>0.06 and X<0.1 then tex.print("\\NC \\NC \\beta_{0.06} \\NC = N \\cdot \\left(-0.3635 \\cdot Z^3 + 2.2124 \\cdot Z^2 - 3.2937 \\cdot Z + 1.8873 \\right) = \\NR") tex.print("\\NC \\NC \\NC = N \\cdot \\left(-0.3635 \\cdot \\sbc{Z}^3 + 2.2124 \\cdot \\sbc{Z}^2 - 3.2937 \\cdot \\sbc{Z} + 1.8873 \\right) = \\sbc {beta006} \\NR") tex.print("\\NC \\NC \\beta_{0.1} \\NC = N \\cdot \\left(-0.1833 \\cdot Z^3 + 1.0383 \\cdot Z^2 - 1.2943 \\cdot Z + 0.837 \\right) = \\NR") tex.print("\\NC \\NC \\NC = N \\cdot \\left(-0.1833 \\cdot \\sbc{Z}^3 + 1.0383 \\cdot \\sbc{Z}^2 - 1.2943 \\cdot \\sbc{Z} + 0.837 \\right) = \\sbc {beta01} \\NR") tex.print("\\NC \\NC \\beta \\NC = 25 \\cdot \\left[ \\left(0.1 - X \\right) \\cdot \\beta_{0.06} + \\left(X - 0.06 \\right) \\cdot \\beta_{0.1} \\right]= \\NR") tex.print("\\NC \\NC \\NC = 25 \\cdot \\left[ \\left(0.1 - \\sbd{X} \\right) \\cdot \\sbc{beta006} + \\left(\\sbd{X} - 0.06 \\right) \\cdot \\sbc {beta01} \\right]=\\sbd{beta} \\NR") elseif X==0.1 then tex.print("\\NC \\NC \\beta_{0.1} \\NC = N \\cdot \\left(-0.1833 \\cdot Z^3 + 1.0383 \\cdot Z^2 - 1.2943 \\cdot Z + 0.837 \\right) = \\NR") tex.print("\\NC \\NC \\NC = N \\cdot \\left(-0.1833 \\cdot \\sbc{Z}^3 + 1.0383 \\cdot \\sbc{Z}^2 - 1.2943 \\cdot \\sbc{Z} + 0.837 \\right) = \\sbc {beta01} \\NR") tex.print("\\NC \\NC \\beta \\NC =\\beta_{0.1}=\\sbc{beta01} \\NR") elseif X>0.1 and X<0.2 then tex.print("\\NC \\NC \\beta_{0.1} \\NC = N \\cdot \\left(-0.1833 \\cdot Z^3 + 1.0383 \\cdot Z^2 - 1.2943 \\cdot Z + 0.837 \\right) = \\NR") tex.print("\\NC \\NC \\NC = N \\cdot \\left(-0.1833 \\cdot \\sbc{Z}^3 + 1.0383 \\cdot \\sbc{Z}^2 - 1.2943 \\cdot \\sbc{Z} + 0.837 \\right) = \\sbc {beta01} \\NR") tex.print("\\NC \\NC \\beta_{0.2} \\NC = max \\left[ 0.95 \\cdot \\left(0.56 - 1.94 \\cdot Y - 82.5 \\cdot Y^2 \\right); 0.5 \\right] \\NR") tex.print("\\NC \\NC \\NC = max \\left[ 0.95 \\cdot \\left(0.56 - 1.94 \\cdot \\sbd{Y} - 82.5 \\cdot \\sbd{Y}^2 \\right); 0.5 \\right] = \\sbd {beta02} \\NR") tex.print("\\NC \\NC \\beta \\NC = 10 \\cdot \\left[ \\left(0.2 - X \\right) \\cdot \\beta_{0.1} + \\left(X - 0.1 \\right) \\cdot \\beta_{0.2} \\right]= \\NR") tex.print("\\NC \\NC \\NC = 10 \\cdot \\left[ \\left(0.2 - \\sbd{X} \\right) \\cdot \\sbc{beta01} + \\left(\\sbd{X} - 0.1 \\right) \\cdot \\sbc {beta02} \\right]=\\sbd{beta} \\NR") elseif X==0.2 then tex.print("\\NC \\NC \\beta_{0.2} \\NC = max \\left[ 0.95 \\cdot \\left(0.56 - 1.94 \\cdot Y - 82.5 \\cdot Y^2 \\right); 0.5 \\right] \\NR") tex.print("\\NC \\NC \\NC = max \\left[ 0.95 \\cdot \\left(0.56 - 1.94 \\cdot \\sbd{Y} - 82.5 \\cdot \\sbd{Y}^2 \\right); 0.5 \\right] = \\sbd {beta02} \\NR") tex.print("\\NC \\NC \\beta \\NC =\\beta_{0.2}=\\sbd{beta02} \\NR") end \stopluacode \stopalign \stopformula \setupformulas[align=middle] I have already tried to insert split=yes in the options of the align environment without success. I have read in "Using \startalign and friends" which is a document dated 2006 that the splitting capability of \startalign is broken. Is it still so? And by the way, is there a clever way to write a block of text under some conditions as shown in the example above other than tex.print(".....") which forces to escape every command? Thank you very much. Bye
