ANN: Metappeal 0.1.0
by Nicola 17 Oct '11

17 Oct '11

Hi, although the following is an announcement of a pure MetaPost library, I thought that it might be of interest to this list, given the tight integration of MetaPost with ConTeXt. Metappeal is an extension to Plain MetaPost, providing a lightweight framework for consistent development in MetaPost. Metappeal 0.1.0 is the second release of this newborn project, bringing you new prominent features: - classes and templates; - delegation; - new basic data structures (bigints, bigstrings); - much better documentation (which is different from "very good documentation"). in addition to a unit testing framework, other data structures (arrays, records, stacks, lists, trees, mboxes, ...) and parametrized code blocks. Nothing graphical yet, sorry, apart from mboxes (getting classes right was hard enough). Metappeal is available from: http://users.dimi.uniud.it/~nicola.vitacolonna/home/content/metappeal and feedback is welcome. Happy MetaPost development! Nicola

\cite doesn't work correctly
by Steffen Wolfrum 16 Oct '11

16 Oct '11

Hi, the \cite command behaves strange, when used in projects: The expected output would be: Me and You; Name, P..Test.. but it is only ; Name, P..Test.. And this result is the same when run from product or from component. Could you have a look a the really very minimal example attatched, please? Thank you, Steffen

arguments on context call
by Meer, H. van der 16 Oct '11

16 Oct '11

The "context --help" shows the following option: --arguments=list set variables that can be consulted during a run (key/value pairs) It looks like something I need at the moment. There seems to be no further information on it, at least not be searching the wiki with "context arguments". I have the two questions: (1) how is the list given? context arguments=key1=value1,key2=value2 or context arguments="key1=value1,key2=value2" or otherwise (2) how are these values picked up inside the TeX-run for use in typesetting?

Hello, I would like to use some tricks described in xmldir manual (only with MkIV) but mtxrun --script tool --dirtoxml stops with /Users/ah/context-old/tex/texmf-osx-64/bin/mtxrun:3248: bad argument #1 to '(for generator)' (directory metatable expected, got nil) Regards Andreas

Spurious space when using space=on with \startlines
by Marco 16 Oct '11

16 Oct '11

Hi, \startlines with the space=on option produces a spurious space. Is that intended? I don't see a reason to introduce a space. %%%%%%%%%%%% \setuplines [style=mono] \starttext % for <whatever> \startlines for <{\it whatever}> \stoplines % for < whatever> \startlines [space=on] for <{\it whatever}> \stoplines % Workaround % for <whatever> \startlines [space=on] for <{\it{}whatever}> % or for<{\it whatever}> \stoplines \stoptext %%%%%%%%%%%% Regards Marco Patzer

luatex math font
by Andreas Richter 16 Oct '11

16 Oct '11

Hello, compiling the following with 'context' \starttext \startformula J:\blackboard{R}^\infty \rightarrow \blackboard{R},f \mapsto J[f] \stopformula \stoptext produces a blackboard 'J' character in J[f] instead of a $J$. The log file contains: system > beware: some patches loaded from cont-new.mkiv fonts > latin modern fonts are not preloaded fonts > latin modern fonts are not preloaded fonts > virtual math > unable to resolve name mapsfromchar fonts > fallback modern rm 12pt is loaded mkiv lua stats > luatex banner - this is luatex, version beta-0.70.1-2011052008 if this is of any help.

MetaFun: hlintext: `! Missing `)' has been inserted.`, `formatstr: ! Not implemented: (pair)-(unknown numeric).`
by Paul Menzel 16 Oct '11

16 Oct '11

Dear ConTeXt folks, trying to draw a grid and label it, I get an error when using the (alsa attached) example from the MetaFun manual [1]. \starttext \startMPcode drawoptions(withpen pencircle scaled .25pt withcolor .5white) ; draw hlingrid(0, 20, .2, 20cm, 10cm) ; draw vloggrid(0, 10, .5, 10cm, 20cm) ; drawoptions(withpen pencircle scaled .50pt) ; draw hlingrid(0, 20,1, 20cm, 10cm) ; draw vloggrid(0, 10,1, 10cm, 20cm) ; fmt_pictures := false ; % use TeX as formatting engine textextoffset := ExHeight ; % a variable set by ConTeXt draw hlintext.lft(0, 20,5, 20cm, "@3e") ; draw vlogtext.bot(0, 10,9, 10cm, "@3e") ; \stopMPcode \stoptext I am using an older version of ConTeXt Standalone. ConTeXt ver: 2011.07.22 17:23 MKIV fmt: 2011.7.25 int: english/english Looking at the log output I could not figure out the original error. Please find the log file attached. Searching the Web I found other threads dealing with this issue. But adding \forceMPTEXgraphictrue as suggested in [2] it does not solve the problem either. Thanks, Paul [1] http://www.pragma-ade.com/general/manuals/metafun-s.pdf [2] http://www.ntg.nl/pipermail/ntg-context/2004/005007.html

Difference in doifinset in MkII and MkIV
by Aditya Mahajan 16 Oct '11

16 Oct '11

The following works in MkIV but fails in MkIV: \unprotect \def\!!yesandon{yes,on} \doifinsetelse{yes}\!!yesandon {\writestatus{TEST}{YES}} {\writestatus{TEST}{NO}} \protect This can be fixed by changing the definition \def\p!doifinsetelse#1#2#3#4% {\donefalse \edef\!!stringa{#3}% \ifx\!!stringa\empty \else - \processcommalist[#4]\p!docheckiteminset + \processcommacommand[#4]\p!docheckiteminset \fi \ifdone\expandafter#1\else\expandafter#2\fi} Can this be changed in syst-gen.mkii? Thanks, Aditya

Lucida \colon, \lll, \ggg
by Hans van der Meer 15 Oct '11

15 Oct '11

I see dat in Lucida (I am using \setupbodyfont[lucida,sans,10pt]) various math symbols are recognized (no error) but their glyphs stay empty in the typeset product. I know there has been some discussion on Lucida and talk of "forgetting pfb's" and waiting for an opentype version. But can this be remedied fairly simply? I am somewhat attached to Lucida and would like to keep using it. Otherwise, is there some good (free) font selection to replace it, even if for the time being? Especially the fit with monotye and math I deem important. Thanks in advance, Hans van der Meer

Exporting verbatim text
by Aditya Mahajan 15 Oct '11

15 Oct '11

Hi, In the vim module, I use vim to generate TeX code that looks roughly as ~~~ \SYN[Type]{public} \SYN[Type]{static} \SYN[Type]{void} main\SYN[javaParen]{(}String args\SYN[javaParen]{)} \{ System.out.println\SYN[javaParen]{(}\SYN[Constant]{"Hello World"}\SYN[javaParen]{)} ; \} ~~~ When generating pdf output, I simply set appropriate catcodes so that the line breaks and leading white spaces are significant. However, when exporting to xml, leading white space is ignored while line break is translated to <break/>. How can I export in such a way that leading white spaces are preserved (and ideally no <break/> is generated, but I can deal with that using CSS). Aditya
