\placelist and \writetolist

Hello! I can't understand what I'm doing wrong here: %%%%% \setuplist[mylist] [alternative=c, width=0mm, style=\tfx, criterium=all] \starttext \placelist[mylist] \page[yes] \input knuth \writetolist[mylist]{}{Item} \stoptext %%%%% The document compiles fine with version 2011.05.18 22:2, but it fails miserably with the latest (2011.11.29 23:11) ! Missing number, treated as zero. system > tex > error on line 11 in file prova.tex: Missing number, treated as zero ... 1 \setuplist[mylist] 2 [alternative=c, 3 width=0mm, 4 style=\tfx, 5 criterium=all] 6 7 8 \starttext 9 10 \placelist[mylist] 11 >> 12 \page[yes] 13 14 \input knuth 15 16 \writetolist[mylist]{}{Item} 17 18 \stoptext <to be read again> , \doplacestructurelist ...um = "#2", number = "#3", extras = "#4", order = "#... \doplacerawlist ...ras }{\listparameter \c!order } \stoplistreferences \endgr... \doplacelist ...ginoflist \doplacerawlist [#1][#2] \doendoflist \dodoubleemptyonespaced #1#2->#1[{#2}][] <to be read again> \par l.11 ? H A number should have been here; I inserted `0'. (If you can't figure out why I needed to see a number, look up `weird error' in the index to The TeXbook.) Thanks in advance. -- Marco

headers: numberconversion=something or \definestructureconversionset
by Philipp A. 13 Dec '11

13 Dec '11

hi list, i want to make an exercise sheet style. exercises are already correctly rendered as “*Exercise <1>: <Text>*”, but sub-exercises should simply be like “*<a>)*”. what i tried: \definestructureconversionset[ex][numbers,characters][numbers] \setupheads[numberconversion=ex] and \setuphead[subsection][numberconversion=characters, …] but i have no idea what i’m doing in the first case and even less idea of what i’m doing wrong in the second. documentation would help in both cases, but contextgarden just has some (for me) incomprehensible examples. thanks, philipp ------------------------------ what i’d really love to have is the following commands, but i’ll figure it out once i have above problem solved. “\sheet” reads the current sheet number from the file name and gives “*Sheet <1>*” as title level header. “\exercise[<descr>]” gives “*Exercise <1>*” without and “*Exercise <1>: <descr>*” as section level header. “\subexercise[<descr>]” gives “*<a>)*” without and “*<a>: <descr>)*” with description as subsection level header.

pdfselect and context command?
by Verhaag, G.C.H.M. 13 Dec '11

13 Dec '11

Hi ConTeXTt User's, I was looking for the --pdfselect option in the context-command, but it doesn't seem to be available. This option is available in texexec to select certain pages from a pdf file. Can it also be done in some way using the context-command? Regards, Gerard Verhaag

Lua and module gnuplot: Manipulate Gnuplot script with Lua
by Paul Menzel 13 Dec '11

13 Dec '11

Dear ConTeXt folks, I have two coefficients saved in a text file -0.157737135681261 -0.211443105668896 and I want to use them to plot a line with gnuplot. Having several of those files I want to use Lua to create the formula for the line for me. I have not yet figured out how to read values from a file in Lua and just tried to print a constant to the gnuplot command. I tried the following. \usemodule[gnuplot] \startGNUPLOTscript[lua] plot \ctxlua{context(1.2 * x + 3)} \stopGNUPLOTscript \startGNUPLOTscript[nolua] plot 1.2 * x + 3 \stopGNUPLOTscript \starttext \useGNUPLOTgraphic[lua] Above should be a plot. \useGNUPLOTgraphic[nolua] \blank \CONTEXT\ \contextmark\ \contextversion \stoptext But only the second plot done and for the first the following error is shown. mtxrun | mtxrun | executing: gnuplot gnup-gnuplot-1.plt mtxrun | mtxrun | plot \ctxlua{context(1.2 * x + 3)} ^ "gnup-gnuplot-1.tmp", line 1: invalid character \ Is there a way to manipulate gnuplot scripts with Lua? Thanks, Paul

Reverse numbering
by Otared Kavian 13 Dec '11

13 Dec '11

Hi all, When using \startitemize[n,reverse] one gets items numbered in reverse order. I wonder if this feature exists also for enumerations. An example is given below in which the last enumeration is written on top of the file and I wish it were possible to have the enumerations numbered in reverse order. Thanks in advance for any insight: OK PS: here is an example file: %%%% enumeration-reverse.tex \defineenumeration[Lecture] [location=hanging, text={Lecture n°}, between=, before=, stopper={.}, after= {\hrule\blank}] \setupenumerations[Lecture][number=yes] % \setupenumerations[Lecture][numbering=reverse] % this has no effect though… \starttext \startLecture Tuesday December 6th: Banach spaces. \startitemize[n] \item First subject. \item Second subject. \stopitemize \stopLecture \startLecture Tuesday November 29th: Norms. \startitemize[n] \item First subject. \item Second subject. \stopitemize \stopLecture \startLecture Tuesday November 22nd: Topological Vector Spaces. \startitemize[n] \item First subject. \item Second subject. \stopitemize \stopLecture \stoptext %%% end enumeration-reverse.tex

Re: [NTG-context] \placelist after \chapter
by Felix Ingram 12 Dec '11

12 Dec '11

Thanks Wolfgang - that works as expected. I'm trying to create a table from the headings (as previously mentioned). Something like this: \setuplist[chapter][criterium=all,alternative=command,command=\MySummaryTable,before={\setupTABLE[frame=on]\bTABLE\bTABLEbody},after={\eTABLEbody\eTABLE}] \define[3]\MySummaryTable{\bTR\bTD #1 \eTD\bTD #2 \eTD\bTD #3 \eTD\eTR} \starttext \placecontent \chapter{First one} \chapter{Second one} \chapter{Third one} \chapter{Fourth one} \chapter{Fifth one} \placelist[chapter][criterium=all] \stoptext While the content gets placed it doesn't appear in a table. I also notice that the same layout is used in the first \placecontent line. In my final document I'd like to have my headings included as usual in the table of contents but then have my own custom list appear as a table later in the document. Is it possible to define a separate format for a list that can be used outside of the ToC? Felix

Hi all, I'm looking for some information on the command \getcitedata [field][key] to \macroname i only manage to get results using a bbl file \input bibtest.bbl is there a way to use it with a bib file directly via \setupbibtex[database=mylib] so i can run context just once? Thanks Michael

\placelist after \chapter
by Felix Ingram 12 Dec '11

12 Dec '11

Hi all, I can't seem to get a list placed after a numbered heading. For example: \starttext \title{First one} \placelist[chapter] \chapter{Second one} \placelist[chapter] % This won't be placed \stoptext Is this something I should be able to do? The reason I ask is that I'm looking to generate a summary table in my document that will contain information from my page titles. I'd like to have the heading title, the page number and possibly some meta-info that I'm passing to my custom command. (I'm planning on passing a custom command in the \setuplist command). If it's not possible to \placelist's after numbered headings then could someone suggest an alternative method? Many thanks, Felix
