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

Hi Hans, has something changed with \definestartstop? Setting before and after do not change the output. \definestartstop[test][before=\blank,after=\blank] \starttext before \test{test} after \stoptext Tested with the current beta- and experimental-branch. Regards Andreas

\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

I should be fairly content with couple of minimal examples, mostlyI manage to elaborate from there once I get the first thing working. Thanks, Mari

Dear Hans and ConTeXt folks, how do you want me to reference ConTeXt? Is there an article you prefer or should I just use the reference manual or the Wiki? Hans Hagen and others (2011), http://contextgarden.net/ Thanks, Paul

gnuplot: `! Undefined control sequence.` with format specifier %
by Paul Menzel 12 Dec '11

12 Dec '11

Dear Mojca and ConTeXt folks, I compiled gnuplot 4.5 from source (master) and got everything running. Mojca, thank you so much! Trying the example from the gnuplot page in the Wiki [1] \usemodule[gnuplot] \setupGNUPLOT[terminal=mp,option=color] % general settings for the whole document \startGNUPLOTinclusions # you may use TeX commands to format the titles and axes set title '\bf Trigonometry' set xlabel '$x$' set ylabel '$y$' set format y '\%.1f' \stopGNUPLOTinclusions \startGNUPLOTscript[tan] plot tan(x) t '$\tan(x)$' \stopGNUPLOTscript \startGNUPLOTscript[sin] plot 4*sin(x)+x t '$4\sin(x)+x$', x t '$x$' lt 3 \stopGNUPLOTscript \useGNUPLOTgraphic[tan] \useGNUPLOTgraphic[sin][width=10cm] even with the comments removed as above I get the following though. [1.1] [1.1] [1.1] ! Undefined control sequence. l.66 \0 .0% ? [1.1] ! Undefined control sequence. l.71 \1 0.0% ? [1.1] ! Undefined control sequence. l.76 \2 0.0% ? [1.1] ! Undefined control sequence. l.81 \3 0.0% ? ^C! Interruption. <to be read again> 0 l.81 \30 .0% ? I hope that is not related to the used ConTeXt version. ConTeXt ver: 2011.11.25 21:29 MKII fmt: 2011.11.25 int: english/english Actually I hope that it is since then upgrading would fix my issue. ;-) Thanks, Paul [1] http://wiki.contextgarden.net/Gnuplot
