I seek how to use context-lua to draw a path from ‘points’ in an external file. Below is one way to plot points from an external file, call the file DATA with contents: 1 3 -2 2 -3 -1 3 -2 \starttext \startluacode local metafun = context.metafun metafun.start() io.input(“DATA") while true do local x, y = io.read("*n", "*n") if not x then break end metafun("filldraw fullcircle scaled 2mm shifted(%dcm,%dcm);",x,y) end metafun.stop() \stopluacode \stoptext How to make this a polygon? I know other ways to read and manipulate DATA with Lua—it is the drawing part where I most look for help. Thanks, John

Dear Fabrice, The following code is working in my mac. I tried your first code and it is working after adding \setupinteraction[]. Since I didn’t use ‘rsteps’ module, I could’t test the second code. My ConTeXt version is as following. ConTeXt ver: 2014.12.21 22:25 MKIV beta fmt: 2014.12.26 int: english/english \setupinteraction[state=start] \setupcolors[state=start] \usemodule[pre-60] \setuppapersize[S4][S4] \starttext \StartSteps \startformula \startalign \NC x^2 + y^2 \NC = z^2 \NR \FlushStep \NC x^2 + y^2 \NC = z^2 \NR \FlushStep \stopalign\stopformula \StopSteps \stoptext I hope that this helps.

Steps in presentation

Hello, I tried to use some steps in a presentation. In the following conversation http://www.mail-archive.com/ntg-context@ntg.nl/msg53524.html, Wolfgang says that we can use the pre-60 module. So I tried this snippet: \usemodule[pre-stepwise] \starttext \StartSteps \startitemize \item one \FlushStep \item two \FlushStep \item three \FlushStep \stopitemize \StopSteps \stoptext But it does not compile: ConTeXt ver: 2012.09.11 20:36 MKIV fmt: 2012.9.12 int: english/english system > cont-new.mkiv loaded (/opt/context-minimals/texmf-context/tex/context/base/cont-new.mkiv system > beware: some patches loaded from cont-new.mkiv ) fonts > latin modern fonts are not preloaded languages > language en is active (pre60.tex resolvers > modules > loaded: 'pre-stepwise' (/opt/context-minimals/texmf-context/tex/context/base/s-pre-60.mkiv fonts > beware: no fonts are loaded yet, using 'lm mono' in box (/opt/context-minimals/texmf-context/tex/context/base/java-imp-stp.mkiv) interactions > javascripts > loaded: library 'stp' metapost > loaded: library 'nav' (/opt/context-minimals/texmf-context/tex/context/base/meta-imp-nav.mkiv)){/opt/context-minimals/texmf-fonts/fonts/map/pdftex/context/mkiv-base.map} fonts > preloading latin modern fonts (second stage) fonts > typescripts > unknown: library 'loc' {/opt/context-minimals/texmf-fonts/fonts/map/dvips/lm/lm-math.map}{/opt/context-minimals/texmf-fonts/fonts/map/dvips/lm/lm-rm.map} fonts > virtual math > unable to resolve name mapsfromchar fonts > fallback modern rm 12pt is loaded !LuaTeX error: There should have been a lua <node> here, not an object with type string! ==> Fatal error occurred, no output PDF file produced! Is there something broken in recent release of conteXt? By the way It seems there is no Rawsteps module anymore but it still is in the wiki. Is there is something like a bugtracker for conteXt, in order to signal when a feature is not working or outdated and signal when it is back (or definitly depreciate)? (it would be a complementary tool for the mailing list)

how to (re)set section numbers
by j. van den hoff 01 Jan '15

01 Jan '15

I have followed the recommendations how to include unnumbered sections in the table-of-content along the lines \setuphead[subject] [incrementnumber=yes,number=no] etc. this works OK if the unnumbered sections are at the end of the document. otherwise the enumeration of the actually (visibly) numbered sections is messed up (i.e. if a `subject' section goes, e.g. _before_ all actually enumerated sections, there counters are off by one). question: what is the best way of (re)setting the section counters? i.e. if the doucment structure is, e.g., \subject \section \subsection \section \subject I'd like to end up with the ToC containing entries for all subjects and sections but the numbered sections should occur (in ToC and document) as 1, 1.1, 2 rather than 2 2.1, 3 (in this example). I was not able to find a solution in the documenation/wiki. thx, joerg -- Using Opera's revolutionary email client: http://www.opera.com/mail/

Using Euler with simplefonts
by Kumar Appaiah 01 Jan '15

01 Jan '15

Hi. I am trying to use the simplefonts approach to get Euler for math, along with TeX Gyre fonts for text. I've looked at some of the past list archives and I haven't yet been able to figure this out. I use TeXLive, and my context is 2014.05.21.20140528-1 (Debian version). Here is the font blurb: \definefontfamily [myfamily] [serif] [Linux Libertine O] \definefontfamily [myfamily] [math] [Tex Gyre Schola Math] Now, I have tried changing the "TeX Gyre Schola Math" to Neo Euler, Euler and some other variants, but it doesn't work. I do have the Euler VM fonts installed on my system. I have also tried the example program given in http://www.ntg.nl/maps/32/06.pdf \definetypeface[eulermath][mm][math][euler][euler][rscale=1] \setupbodyfont [eulermath] \starttext \showmathcharacters \stoptext This works with texexec, but with context, it chokes. Could you please provide me some pointers? Thanks. Kumar

\mathcases and equation numbering
by j. van den hoff 31 Dec '14

31 Dec '14

I posted a similar question a few days ago without success/response but since I have not found a solution anywhere I would like to ask this again: how can I get properly enumerated equations using `\mathcases'? this example does not work: \starttext bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla \placeformula \startformula E(f) = \frac {K_1(f)} {f} \stopformula \placeformula \startformula K_1 \rightarrow \startmathcases \NC f \NC for $f \ll PS$ (flow limited transport) \NR \NC PS \NC for $f \gg PS$ (diffusion limited transport) \NR[+] \stopmathcases \stopformula bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla \stoptext since (as I now have "discovered" myself) the `\NR[+]' is here intended for subcases enumeration (which are, thus not aligned with the right margin0, rather than (like with \mathalign) for whole equation numbering. but omitting the `[+]' does not help either since \placeformula simply does not put an equation number at all. so, simple question: how to get a properly numbered equation using \mathcases? thx,joerg

g parameter in tabulate stopped working

When preparing my last invoices for 2014, I stumpled upon an error in tabulation: \starttext \setuptabulate[distance=0pt] \starttabulate[|lw(7.75cm)|rg(,)w(2cm)|rg(,)w(2cm)|cg(,)w(3cm)|] \NC Text \NC 1,00\NC 222,22\NC 3,33\NC\NR \NC Text \NC 2\NC 5,5\NC 66,666\NC\NR \NC Text \NC 100,00\NC 44,44\NC 33,33\NC\NR \stoptabulate \stoptext In the log I get 3 times (i.e. once per g parameter): tabulate > unknown preamble key: ) and of course the numbers are not aligned around the comma.

Footnote breaks tagging

Hello everybody and thanks in advance for your advice, I’m unable to find in the documentation and in the wiki the way to start an itemized list with a number different from 1, for instance with 3. What I want to achieve is something like: Insert the key Try to turn the key If key is working 3. Open the door If key is not working 3. Change key 4. Goto step 1 So what is the way to start the list after « If key is not working » with the number 3 ? Eric Gerard

handling HTML notes in ConTeXt

fluctuating baseline of header text
by j. van den hoff 28 Dec '14

28 Dec '14

I observe a slight fluctuation of the baseline of text in the page header when going from one page to the next. a minimal example follows: \setupheader [style=\smallbodyfont\ss\it] \setupheadertexts [section] \setuppagenumbering[location={header,margin}, style=\bfc] \starttext \section{Introduction} bla \page[yes] \section{Introduction} bla \page[yes] \section{Introduction} bla \page[yes] \section{Introduction} bla \page[yes] \section{Introduction} bla \page[yes] \section{Introduction} bla \page[yes] \section{Introduction} bla \page[yes] \section{Introduction} bla \page[yes] \section{Introduction} bla \page[yes] \section{Introduction} bla \page[yes] \stoptext in this example (and with this font) the problem is only occuring when toggling between pages 6/7 or 7/8 (at sufficient zoom it's easy to see), i.e.the header is shifted downward on page 7. in other docs with different fonts it happens across multiple pages. my guess would be it has to do with the digit heights in the different fonts and the fact that the page numbers are much larger than the heading, but that's only a guess. can someone confirm the problem? thx,joerg -- Using Opera's revolutionary email client: http://www.opera.com/mail/
