Marking a textfragment for later reference
by Robert Blackstone 05 Aug '12

05 Aug '12

Dear list, How can I refer to some text, for example a discussion of a particular topic, on another page or in another chapter of my document with, for instance "(See discussion on page xx)"? I tried to do this by marking the relevant text as a delimited text without altering its layout: \definedelimitedtext[topica] \setupdelimitedtext[topica][left=,right=] %maybe superfluous? \starttopica some text \stoptopica and then, further on, referring to that text with (See discussion on \at{page}[topica]) But this does not work (mkiv 27-07). Thanks in advance for any advice. Best regards, Robert Blackstone

Bug in \startitemize[randomize]
by Aditya Mahajan 05 Aug '12

05 Aug '12

Hi, \startitemize[randomize] does not randomize properly (one entry at random is gobbled and another is repeated in its place). I guess that this is because of an off-by-one error somewhere. Example (from: http://tex.stackexchange.com/a/65662/323) \defineitemgroup[institm] \setupinstitm[1][text, random] \setupinstitm[1][symbol=2, indentnext=no, intro=yes] \starttext \startTEXpage[offset=5mm] \bold{Contributions} \startinstitm \startitem Foo Pvt Ltd {\sc nsw} \stopitem \startitem Bar Pvt Ltd {\sc vic} \stopitem \startitem Baz Pvt Ltd {\sc abc} \stopitem \stopinstitm \stopTEXpage \stoptext Aditya

Strange bug with \ in footnotes
by Aditya Mahajan 05 Aug '12

Hi, I usually use \ after abbreviations to avoid bad interword spaces. For example, Prof.\ ABC. However, when using this in footnotes, if there is a linebreak after the \, I get an error: ! Undefined control sequence. 1 >> \starttext 2 Someone\footnote{Prof.\ 3 ABC} 4 \stoptext 5 l.1 Prof.\ ABC \ctxcommand ...\directlua \zerocount {commands.#1} \handlenoteitself ...text \strc_notes_inject_text \endstrut \strc_constructi... \handlenoteinsert ... {\handlenoteitself {#1}{#2}} \egroup \the \everyafterno... \195>notation:note ...rentnote \currentnotenumber \fi \fi \endgroup \fi \fi ... \strc_notations_command_nop ...handler \endcsname \strc_constructions_finali... l.3 ABC} Minimal example (There should be a linebreak after \) \starttext Someone\footnote{Prof.\ ABC} \stoptext What's going on here?

Bug with setupinteraction and footnote

Hi Hans, With the latest beta (ConTeXt ver: 2012.08.04 14:00 MKIV fmt: 2012.8.5) the following use of \setupinteraction[state=start] and \footnote causes a luatex error: %%%%%% \setupinteraction[state=start] \starttext While testing footnotes\footnote{This is a footnote.} we encounter a bug with \type{\setupinteraction}. \stoptext %%%%%% The error message starts with: > !

Hi, \checkparameters seems broken in the current beta. The following example used to work at least with version 2012.06.13 --------------------------------------------------------------------------------- \def\myCom[#1]{% \checkparameters[#1] \ifparameters \getparameters[do][one=1,two=2,#1] \doone\ \dotwo \else #1 \fi } \starttext \myCom[one] \myCom[one=one,two=two] \stoptext --------------------------------------------------------------------------------- … while with the current beta (2012.08.02) it results in: system > tex > error on line 11 in file testcheckparameters.tex: Undefined control sequence ... 1 \def\myCom[#1]{% 2 \checkparameters[#1] 3 \ifparameters 4 \getparameters[do][one=1,two=2,#1] 5 \doone\ \dotwo 6 \else 7 #1 8 \fi 9 } 10 \starttext 11 >> \myCom[one] 12 13 \myCom[one=one,two=two] 14 \stoptext \checkparameters ..._helpers_get_empty_parameters #1=@@\_e_o_s_ \myCom [#1]->\checkparameters [#1] \ifparameters \getparameters [do][one=1,t... l.11 \myCom[one] Thanks in advance, Daniel

Using MPgraphics as externalfigures?
by Mari Voipio 03 Aug '12

03 Aug '12

Hi All, I'm being a bit clueless about the MPgraphics again... I've got a pile of instructional graphics that will be used and reused in a project. My first try is/was an unwieldy buffer construction, but I'm sure there's a better way than \placefigure[here] [fig: 5 loop departed setup] {The start position for a 5-loop braid with departed loops} {\framed{\getbuffer[setup 5-loop basic]}} Come to think of it, is there another way of framing the incoming graphic? I don't want to include the frames in the MPcode as I may not always want them, but that \framed{\getbuffer} construction is downright ugly. I think the solution to my problem can be found somewhere in the \startreuseagleMPgraphic and \reuseMPgraphic, but I don't seem to be able to figure out the last bits... On the moment my MPgraphics have \startbuffer[g1] \startMPcode ... \stopMPcode \stopbuffer but that's probably an overkill... And I'd really prefer to have the graphic as just a pic so I can easily use them as external figures. Of course one option would be to pdf the MPgraphics and then to insert the pdf, but I'd prefer to skip that step. Any ideas of how to do this in a smart way? Preferably without having to go into the bowels of ConTeXt to get it done... Thank you, Mari

Or should I guess Fontforge? it doesn't handle scripts at all .. luatex only provides access to the font data on the one hand and access to the typesetter at the other end ... everything in between has to be done in lua concerning indic ... the fonts does not have all the info so additional code is needed (will be in context some day soon) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

author-title cite command
by Daniel Schopper 03 Aug '12

03 Aug '12

Dear list, I'm trying to come to grips with creating a customized author-title cite command, based on this[1] thread. I was wondering how I can check on the value of the [artauthor] or [author] fields extracted by \getcitedata? Eventually I'd need a footnote citation style that prints a full citation for the first reference and then uses a author-title style for the subsequent ones: For @incollection only author and title of the article, for @book the author and title of the book. Which is why I'd need to for the existance of an artauthor… Or how can I just grab the bibtex-type? \getcitedata[bibtype] doesn’t seem to return anything. I guess this should be quite easy for someone more experienced. TIA, Daniel \setupbibtex [database=sample] \setuppublications[alternative=apa] \def\MYauthor#1#2#3#4#5{#3} \def\specialcite#1[#2]% {\bgroup \getcitedata[author1][#2] to \mauthors \getcitedata[artauthor1][#2] to \martauthors \getcitedata[arttitle][#2] to \marttitle \getcitedata[title][#2] to \mtitle \getcitedata[bibtype][#2] to \mbibtype \doifsomethingelse{\marttitle}{\marttitle}{\mtitle} % This works % % Pseudo-Code: \doifsomethingelse{\martauthors}{\martauthors}{\mauthors} % This, of course, doesn't \mbibtype % This neither \egroup} \starttext \cite[hh2010a] \cite[Eijkhout1991] \specialcite[hh2010a] \specialcite[Eijkhout1991] \stoptext [1] http://www.mail-archive.com/ntg-context@ntg.nl/msg55534.htm

alternative command for lists
by Willi Egger 03 Aug '12

03 Aug '12

Hi all, At the moment I am busy to build a custom TOC. I stumble overt the fact, that ConTeXt seems to forget all parameters set in \setuplist once you issue alternative=command, command=… Could anyone of you enlighten me whether I miss something? Kind regards Willi P.S. Please refer to the attached minimal example.
