new beta
by Hans Hagen 28 Jul '10

28 Jul '10

Hi, I uploaded a new beta that can deal with the new mplib. The biggest side effect of the new lib is that no longer formats are made and that the 'format related code' (read: metafun) is loaded at runtime. In the future I might optimize this but at the moment it's not needed. For a while both methods will be supported. The latest version of mplib can process the metafun manual without crashing or hanging which is a good sign.

Minimals without rsync - again?
by Richard Stephens 28 Jul '10

28 Jul '10

Hi all, On the wiki at http://wiki.contextgarden.net/ConTeXt_Minimals/FAQ is says: "Blocked Firewall port You are most probably behind a firewall. Make sure that port 873 is open. If you cannot make any changes yourself and if your admin objects, you probably won't be able to use rsync for the distribution." Yes, I am behind a firewall. No, port 873 is not open. No, I cannot make any changes, and yes, my admin objects :-( So what's the alternative to using rsync? I used to use the zip file at http://www.pragma-ade.com/download-4.htm but that doesn't exist any more! I've now managed to screw up my MKIV installation somehow, so I desperately need some way of getting the beta release re-installed without rsync. Help!! Richard Converteam UK Ltd.

Multi-line labels in MetaPost MKIV
by Richard Stephens 28 Jul '10

28 Jul '10

Hello all, What is the recommended method for creating multi-line labels in MetaPost in MKIV, please? I have the following code: \definetextext[mplabel]{\framed[frame=off,align=middle]} \starttext \startMPpage input mp-tool; draw fullcircle scaled 5cm; label(\sometxt[mplabel]{One\\Two}, (0,0)); \stopMPpage \stoptext which gives a line feed between One and Two using MKII, but no line feed in MKIV.

relative size of symbols
by Henning Hraban Ramm 28 Jul '10

28 Jul '10

Hi ho, I need some symbols from a font, but they are too small in comparison to my text font. (It used to look right once, maybe now some font feature is handled different.) I know only the scaling options in type scripts, but how can I scale my glyphs in this setup? (minimals, latest beta, mkIV) \definefontsynonym [Symbola] [file:Symbola.otf] \def\UnicodeSymbol#1{\getglyph{Symbola}{\utfchar{#1}}} \def\born{\leavevmode\raise0.09em\hbox{\UnicodeSymbol{"2733}}} \definefontsynonym is missing in the command reference. Greetlings from Lake Constance! Hraban --- http://www.fiee.net/texnique/ http://wiki.contextgarden.net https://www.cacert.org (I'm an assurer)

Semantic data in ConTeXt?
by Matija Šuklje 28 Jul '10

28 Jul '10

Hullo, this is something that's been bothering me for quite a while: Will ConTeXt support semantic meta-information? A few examples: * could ConTeXt automatically tag the PDF it creates e.g. via Nepomuk[1]? * could the bibliography be enriched with RDF triples? * by selecting an event or contact mentioned in a document made by ConTeXt, could you import that into your organiser or address book? * if a document made by ConTeXt was put online, could meta-data inside it reveal the semantic meaning of its contents and creator for easier searching? * ditto for local storage? From my understanding this depends on whether PDF can have RDF included and/or whether ConTeXt could output to ODF. Currently KOffice is leading the pace here with OOo just a bit behind it and AbiWord still needing to catch up. There's an interesting article[2] in Linux Magazine about how KOffice uses libferris to integrate RDF into ODF. With semantic web and semantic desktop creeping up at a fast pace, it'd be a pity not to make use of it IMHO.

Setting up protrusion, side-effects
by Martin Althoff 28 Jul '10

28 Jul '10

When setting up protrusion, I noticed it "disappearing" despite being defined/setup. In a text, when I changed the font from Palatino to Sabon (with \setupbodyfont[sabon]), protrusion stopped working. Changing back to palatino, with nothing else changed, protrusion appeared again. Note: getting the latest minimals update did not change anything: context: version: 2010.07.27 16:30, LuaTeX, Version beta-0.60.2-2010070117 on OSX 10.6.4 The following test file showed that if the \setupbodyfont takes place before \definefontfeature and \setupalign, protrusion fails completely. In the example 1 below it fails. Disabling the top \setupbodyfont and enabling the bottom \setupbodyfont gets it to work. However, it will fail for both Palatino and Sabon! I could not create an example for one font working and the other not. Is the order of declaration important? That would be unusual in context by what I have seen so far. Am I missing something? Example 1: \setupbodyfont[palatino] % protusion Einstellungen \definefontfeature [default][default][protrusion=quality,expansion=quality] \setupalign[hz,hanging] %\setupbodyfont[palatino] \showframe \starttext \input tufte \stoptext Possibly related is the following. Executing \showbodyfont for palatino with protrusion enabled messes up the text following it. The same done with Sabon is no problem. The Example 2 below illustrates the problem. I have attached the PDF to show the output. While this obviously not a real problem, as the \showbodyfont won't be in a final output, it might hint at an underlying problem, possibly related to the above problem. Example 2: % Set up protusion \definefontfeature [default][default][protrusion=quality,expansion=quality] \setupalign[hz,hanging] \setupbodyfont[palatino,12pt] \showframe \starttext \showbodyfont \input tufte \switchtobodyfont[sabon,12pt] \showbodyfont \input tufte \stoptext

help with startformulas and startalign
by Julian Becker 27 Jul '10

27 Jul '10

Hi everybody, I'm new to ConTeXt and need a little expert help. When I'm running the following 'test.tex' file ------------------------ \starttext \placeformula \startformulas \startformula \startalign \NC A \NC = B \NR[+] \NC C \NC = D \NR[+] \stopalign \stopformula \startformula E \stopformula \stopformulas \stoptext ------------------ I get the following errors: systems : begin file test.tex at line 1 ! Missing $$ inserted. <to be read again> \Ustopdisplaymath \stopformula ->\normalstopformula \egroup \Ustopmath \hss <argument> ...= D \NR [+] \stopalign \stopformula \startformula E \stopformula \dostartformulas ...la \egroup \Ustopmath \hss }#2 \egroup \stopdisplaymath \... l.12 \stopformulas ! You can't use `\Ustopdisplaymath' in horizontal mode pages > flushing realpage 1, userpage 1, subpage 1 systems : end file test.tex at line 14 Does anybody know how to do this right? Startformulas itself works allright, if I leave out the alignment part. I also tried startmathalignment instead, but it gave the same errors. Best regards, Julian
