This is the hex unicode reference for the entity ⁡ which is already defined in xtag-mml.tex as nothing ({}) via its expansion into ⁡. So the problem seems to be in arriving at ⁡ from ⁡. I'm not sure how to do that, but in the meantime you can define ⁡ explicitly using: \defineXMLentity [x02061] {} I think there is a mapping mechanism though, since a lot of Unicode is supported natively; perhaps the vector to which ⁡ belongs hasn't been completed yet.

At the moment I have no idea how most of the Chinese module or font-handling works, nor how I would implement something using the tricks you describe. I guess I would need some hand-holding if I were to embark on this, I guess also I would need to understand the mechanism used to re-use a TTF font many times with different encodings to create multiple 256 char tfms. > another option is to write another mapper analogue to the ones > already there for chinese, i.e. is there some mapping from utf to > big5 or so and hook that into the utf handler. This sounds like something I can at least understand a bit better. I will start here, and see what success I have. Perhaps it will help eventually with an attempt to do it the "right" way above. > (beware, the font-chi modules talk about unicode while actually it's > about dedicated mapings resembling a unicode approach; this > \defineucharmapping stuff) Yes indeed, that had me going... :-) Oh well. Thanks for the insight, I'll feedback further. Duncan

That finally ocurred to me after you all were sleep yesterday-) Yes, the \unexpanded solves things. I'm curious: how exactly does \unexpanded work? Is this an eTeX primitive?

bib module: interaction (wish)
by Giuseppe Bilotta 11 Oct '05

11 Oct '05

Hello all, and Taco in particular, I'm a great fan of interaction, and I was wondering about what kind of interaction the BibTeX module could support. I'm thinking of two of them in particular. One of them is the obvious link to list of references on click. However, I'm also a great fan of balloons, so I was thinking of something like a popup-on-hover showing the full reference, thus sparing the need to go back-and-forth through the document. (Can these things be optimized so that the popup is only stored once in the PDF?) A potential problem would be with compressed citations, but I guess that in this case making only the displayed numbers active is the right solution. -- Giuseppe "Oblomov" Bilotta

last-name only in bib
by Idris Samawi Hamid 11 Oct '05

11 Oct '05

Dear Taco, I need a last-name only option for a few but not all authors, such that no comma comes after the last name; rather it goes straight to the year e.g., it appears in the actual bibliography as ============================================== McDermott (1976). The Theology of Shaykh Mufid ============================================== Right now I get (with spurious comma) ============================================== McDermott, (1976). The Theology of Shaykh Mufid ============================================== Sometime authors give me bib's where the first name of the author is unknown...

hyperlinking files
by andrea valle 10 Oct '05

10 Oct '05

This should be obvious but I wasn't able to find a fitting example. I'm a having great time creating my pdf slided with context. Now, I'd like to have a link opening a video/audio/html file. How can to do it? I tried with wiki. I'm able to use a .mov, but not an .mpg. What does it depends on? Can I play a .wav from inside the pdf? Thanks -a-

Anchoring layer
by Thomas A. Schmitz 10 Oct '05

10 Oct '05

I'm trying to write a module that will mimick the behavior of crop.sty in LaTeX (providing fancier cropmarks than the ones given by the ConTeXt \setuplayout command). I'm done with the code for the cropmarks, and this is working fine. Now I want to have a status line in between the two top marks. How can I give an absolute position for a layer that will put this line midaligned and exactly, say 0.5cm above the level of the upper corners of the page? What I tried so far is: \composedlayer and something like \setlayer[y=2cm] - will only be on the first page, not repeated; \framed - I can give the frame a height like 1.3\textheight, but then the position will not be fixed, but change with the textheight I guess there must be a trivial solution, but I haven't found it yet...

esoteric macro expansion bug in t-bib?
by Idris Samawi Hamid 10 Oct '05

10 Oct '05

esoteric macro expansion bug. Dear Taco, There is some esoteric macro expansion bug in the bib module (beyond my capability to understand). For example, the \Ibar macro works fine outside of the a= context. \getcommacommandsize can't seem to figure out that ## stands for an alignment preamble. Is there a way to protect the argument of a= ? Please try the following : ================ibar-bib.bbl==================== \startpublication[k=amini93, t=book, a=al-Am\={i}n\~i, y=1993, s=] \author[]{Mu\.hammad H\=ad\=i}[]{}{Al-Am\=in\=i} \title{Mu\`allimu \~a\~l-\v S\=i\`ah: a~l-\v Say\h h al-Muf\=id} %\pubname{} \city{Beirut} \pubyear{{1993}} \stoppublication =========================================== ================ibar-bib.tex==================== % output=pdf interface=en \usemodule[bib] \def\SHIFT#1{\dimen0=.00#1ex \multiply\dimen0 by\fontdimen1\font \kern-.0156\dimen0} % compensate for slant/italic in lower accents \def\USHIFT#1{\dimen0=.00#1ex \multiply\dimen0 by\fontdimen1\font \kern.0156\dimen0} % compensate for slant/italic in upper accents \def\IBAR% {\leavevmode\vbox{\offinterlineskip\lineskip0.295ex% \ialign{##\cr\USHIFT{120}\hfill\hbox to .21243em{\leaders\hrule height .07ex\hfill}\hfill\SHIFT{1}\cr\i\cr}}} \definecharacter imacron {\IBAR} % ConTeXt-dependent! \setupwhitespace[big] \starttext \cite[amini93] M\=irz\=a \section{References}{\tfx\setupinterlinespace {\leavevmode\placepublications}} \stoptext =========================================== I get the following error =========================================== systems : begin file ibar-bib at line 20 !
