How can one center or align a float?
by Otared Kavian 09 Apr '10

09 Apr '10

Hi all, How is it possible to have a STEPchart be midaligned, or right-aligned, as one may do this with figures, tables, and FLOWcharts? An example is here: %%%%%%%%%%%% \usemodule[steps,mathml] \starttext \startbuffer[test-chart] \startSTEPtable \cell {$c=2a+3b$} \text {with $a=5$} \cell {$c=10+3b$} \text {and $b=6$} \cell {$c=10+18$} \text {we get} \cell {$c=28$} \stopSTEPtable \stopbuffer How can one center the following \type{\STEPchart}? \getbuffer[test-chart] \stoptext %%%%%%%%%%%% I should add that \startalignment[middle], or \placefigure do not have any influence on the alignment of the above example. Thanks in advance an best regards: OK

Hello people, I installed Mac TeX -2009 Distribution on a new iMAC. when I try to run texexec on a Context file that includes a metapost program, I receive no picture that is defined in metapost part. (btw in my linux installation it works) What I can find in log file is: ... runsystem(texmfstart texexec --batch --output=dvips --mpformat=metafun --mptex --nomp --once obrazek-mpgraph)...disabled. ... Running this sequence manually and reruning the 1st texexec I receive what I expect. Is it a feature of Mac distribution or there is a mismatch in some file/directory permissions? (mptopfd, ...) Are there another installation steps needed after fresh MacTeX installation? the test file is: \startuseMPgraphic{def} ... \stopuseMPgraphic \startuseMPgraphic{obr30} \includeMPgraphic{def} ... \stopuseMPgraphic \starttext test \placefigure[here][fig1]{yyy} {\useMPgraphic{obr30}} end of test \stoptext Nice day, Jindro

4th ConTeXt Meeting: Call for submissions
by Jano Kula 06 Apr '10

06 Apr '10

Dear all, 4th ConTeXt Meeting is closer now and it's time to think about its programme. --------------------------------------------------------------------- = Call for submissions = As in previous years, anything at all related to ConTeXt that you would like to share is an acceptable subject for a presentation, tutorial, discussion, Q&A session, demonstration, workshop, recital, sketch, or sermon. That said, this year Hans and Taco decided that it would be wise to focus a bit on documentation issues. The informal theme is therefore: *ConTeXt typesetting documentation, teach as we preach* It follows that if you have something to say on educating users on how to best use ConTeXt or to developers on how to best document ConTeXt (and who doesn't have an opinion on those topics!) your submission will be all the more appreciated. The programme committee is Hans Hagen Hagen and Taco Hoekwater, feel free to email them with hints and ideas. Because we want something interesting on the website, abstracts should be sent in before May 31 or even now, before opening the registration. --------------------------------------------------------------------- http://meeting.contextgarden.net/2010/ The page has been updated. We hope you won't get lost and everybody can find his way to Brejlov (see the 'location' part). The registration opening will follow shortly. We will inform you here, on the mailing list.

Indent of heading when using command option
by Jan Pohanka 05 Apr '10

05 Apr '10

Hello, I have following code (simplified) \def\mySubject#1{#1} \setuphead[subject][style=\bfb\ss,color=HeadColor,before=,after=,textcommand={\mySubject}] When the command option is not set it works as expected and typeset the heading (subject) without any indenting, but using the command causes the small horizontal space in front of the subject. Is there any possibility to get rid of it? best regards Jan -- Tato zpráva byla vytvořena převratným poštovním klientem Opery: http://www.opera.com/mail/

Mk II, textstyle=cap not working
by Michael Ewe 05 Apr '10

05 Apr '10

Hello ConTeXt gurus, as a newbie I checked the example from "ConTeXt an excursion" page 11 ("Hasselt makes headlines"). The manual says: use "textstyle=cap" to format a chapter's head in capitals. Short story: the manual lies ;-) The sample does not work (at least in Mk II) Longer story: Sample works, when using ConTeXt Mk IV Even longer story: Being curious, I wanted to learn how the page 11 in the manual actually was typeset. I downloaded all the available sources from the pragma web-site. and found out: the source code does not even use "textstyle=cap". Instead it uses "textstyle=bold". Manual and available source apparently do not match. Nothing to learn here... Ok, now for my questions: 1) Is it a Mk IV feature not working in Mk II ? 2) Is it a bug? 3) Is there a way, I can tell (1) and (2) apart? Best Regards, Michael Ewe, Germany

Is there a SVG to MetaPost/MetaFun converter available? I want to get this quite simple logo to converted from SVG into a ConTeXt- native vector graphic. Cheers, Matija P.S.

Multiple side-by-side tables

I would like to put several tables side-by-side one another. Nesting \placesidebyside commands seems a bit inconvenient. Suggestions on how to make \starttable ... \stoptable not create a newline (without the \placesidebyside command) would be greatly appreciated. -- Troy Henderson

temporarily disabling enumeration numbering
by Vianney le Clément 05 Apr '10

05 Apr '10

Hello again, Section 10.3 of the manual says that one can disable numbering for one item of an enumeration by putting [-]. However, this seems to affect the following item instead of the current one. For example, \defineenumeration[MyEnum][location=left] \starttext \MyEnum First\par \MyEnum[-] Second\par \MyEnum Third\par \MyEnum Fourth\par \stoptext removes the number of the third line, instead of the second one.

\framed[location=top] and slanted tex gyre bonum
by Vianney le Clément 05 Apr '10

05 Apr '10

Hello, Yet another new ConTeXt user here. To briefly introduce myself, I am a computer scientist interested in typography as a hobby. Up to now, I did most things in LaTeX (sometimes resorting to ugly TeX hacking). Recently I gave ConTeXt MkIV a try and am quite happy with it. Now my question: I have some problems with the vertical alignment of \framed and some slanted fonts. Using the latest beta, the test file at the end of this message adds a slight whitespace in the two last blocks (using a slanted font). This does not happen when using the default Latin Modern font. Is this a bug or am I doing something wrong?

Splitting a page in given ratios
by Matthias Weber 05 Apr '10

05 Apr '10

Dear all, this is probably even easy in plain TeX, but as I have never learned it properly, I am asking anyway: I would like to have a way to split a part of a page into two columns of different width, so something like \startsplitpage[columns=2,spacing=fill] \startcolumn[1][width=.6 \textwidth] \input{tufte} \stopcolumn[1] \startcolumn[2][width=.3 \textwidth] \placefigure[theBeerBottle] \stopcolumn[2] \stopsplitpage so that the individual columns are treated (if possible) as separate pages with all features (like \framed etc) adapted to the page width of the smaller sub-pages. This could replace (for me) the somehow (for me) disfunctional figuretext construct. Is there a way to do this? Thanks, Matthias

Need help with the "letter" module
by Matija Šuklje 05 Apr '10

05 Apr '10

Hullo, I'm trying to write a letter, but it gets all screwy. The first batch of letter settings works OK (opening, closing, signature); but then the from* and to* blocks fail resulting in a PDF that just quotes that code on a separate page. Clearly I'm doing something wrong although I'm looking at the manuals: http://dl.contextgarden.net/modules/t- letter/doc/context/third/letter/correspondence.pdf MkII from TexLive 2008.

caption on the inner side
by Hubertus 05 Apr '10

05 Apr '10

Hello all, I was wondering if it possible to do something of this sort: \setupcaptions[location=low] \placefigure[outer][]{ Caption } {\externalfigure[test.jpg][width=0.5\textwidth]} So what I try is to get the caption not on the left side of the image but "inner". From the location pramametar there seems not to be an obvious solution, neither in the mail archive. Cheers, Hubertus

missing \xmlflushsetups?

I thought one can register various setups and then when setting up the processing of the root tag call them into being with: \xmlregisteredsetups (according to the docs "applies all global setups to the current document) But doing this as in: \startxmlsetups xml:doc:roottag xmlregisteredsetups ... I get instead the error: !

Hans' presentation: using plain TEX (from TUG 2009) [apologies if OT]
by Graham Douglas 04 Apr '10

04 Apr '10

Dear Hans, Taco et al I hope this is the appropriate place to ask my question --- if not, my apologies. I've compiled LuaTeX on Windows and have been using Hans' presentation "using plain TEX" (from TUG 2009) to construct a minimal working runtime environment based on plain tex. Basically, a hand-coded texmf.cnf and a minimal (non-ConTeXt) environment/TDS constructed around the "build" directory created by build.sh. The reason for doing this is to start with a setup which is the minimum possible, as a way to learn. ConTeXt is very powerful and orders of magnitude more complex than plain (obviously...) so I needed to strip that away, for now. It seems to work well, so far. My question relates to fonts. In the luatex-plain example: \input plain \directlua {tex.enableprimitives('', tex.extraprimitives())} \pdfoutput=1 \everyjob \expandafter {% \the\everyjob \input luatex-basics\relax \input luatex-fonts\relax \input luatex-mplib\relax } \edef\fmtversion{\fmtversion+luatex} ===> luatex --ini luatex-plain.tex You include some ConTeXt font machinery which I'd like to experiment with using fonts I have in .afm/.pfb format only. I ran mtxrun --script font --names to generate a font name database (luatex-fonts-names.lua) ["mappings"]={ ["aharonibold"]={ "Aharoni Bold", "C:/Windows/fonts/ahronbd.ttf" }, ["andalus"]={ "Andalus", "C:/Windows/fonts/andlso.ttf" }, ["angsananew"]={ "Angsana New", "C:/Windows/fonts/angsa.ttf" }, ["angsananewbold"]={ "Angsana New Bold", "C:/Windows/fonts/angsab.ttf" <<snip lots>> and copied it across to my plain tex texmf tree. Works fine, PDF outputs perfectly, so it enables lots more fonts in the plain format. However, the database is clearly restricted to TrueType and OpenType fonts so my question is: Does the font machinery included by: \input luatex-basics\relax \input luatex-fonts\relax \input luatex-mplib\relax provide support for afm/pfb fonts? TrueType etc are OK like this: \font\testf=[arialbolditalicmt] at 12pt (name taken from database) However, as soon as I try to use this with afm/pfb files it fails, unable to find the metrics. For example: \font\testa=file:MinionRegularItalic_wt350_wd450_op10 at 34pt It may be potentially bad names that I'm using with underscores (they are all named like this Minion_wtX_wdY_opZ) (X,Y,Z are values for weight, width and optical size) But it also failed with simple font names. I checked that the fonts can be found: \directlua { local found = kpse.find_file("MinionRegularItalic_wt350_wd450_op10","afm") tex.print("$$"..found.."$$") local ifound = kpse.find_file("MinionRegularItalic_wt350_wd450_op10","type1 fonts") tex.print("$$"..ifound.."$$") } ($$ is a silly hack due to the _) So, is it possible to find and load .afm/.pfb with your luatex-plain example. Is that font machinery included in luatex-plain? If so, can you suggest why the luatex-plain example might be failing with the .afm/.pfb files? I would be very grateful for any insights you can provide. Many, many thanks in advance. And another busy day on the list!!! Warm wishes Graham
