\installprettytype problem
by Matthieu Leroy 21 Aug '15

21 Aug '15

Hello, I want to use the " C-Pretty-Printing <http://modules.contextgarden.net/pret-c>" module. According to the "Verbatim" page of the Context garden, I have to use the \installprettytype command, but this one doesn't work (error : "undefined control sequence"). I'm using the 2015.08.13 19:33 Context version. Example : \installprettytype[C][C] \definetyping[C][option=C] \startC int func(int a){ if(a > 4) return 0; // comment else /* comment */ return 10; } \stopC Thank you.

Do you mean numeric a[n]? It was not explicitly declared; I did not think it needed to be—the show commands write what I expect to the log—anyway, declaring a did not help. > > also, use > > a[n] := scantokens v[n] ; Done.

\startchemical
by Wolfgang Schuster 21 Aug '15

21 Aug '15

Hi, why does \startchemical take the name of a instance as argument (e.g. \startchemical[important]) when there is no way to create it because \definechemical is redefined and the original version isn’t saved. Even \setupchemical[important][..,..=..,..] can’t be used because it doesn’t resolve the parent setting. Wolfgang

Bad PDF to text crawlers
by Kip Warner 20 Aug '15

20 Aug '15

Hey list, I have an important document online that I would prefer to keep as a PDF and not in another format. Unfortunately bots frequently try to provide those looking for it with a text version they try to extract (beyond my control). The extraction looks just absolutely awful and has been a major pain in leaving readers with a really bad understanding of the contents of the document. I was thinking that there must be some way of tricking these bots, depending on how they are implemented, and let's assume they will always find the PDF, to get them to extract only a small invisible layer that just contains some hidden text directing a user to the location to download the original high quality ConTeXt PDF. Any suggestions? -- Kip Warner -- Senior Software Engineer OpenPGP encrypted/signed mail preferred http://www.thevertigo.com

\setupwhitespace and Natural Table paragraphs
by Pavneet Arora 18 Aug '15

18 Aug '15

I am trying to find the most effective way of changing paragraph spacing for paragraphs inside table cells, without resorting to explicit \blank directives. Here is a MWE to show what I mean. Outside of the table, the paragraph spacing seems to honour the \setupwhitespace directive. Not so inside the table. Curiously, though, the default enumeration inside the table *does* seem to honour \setupwhitespace, which you can affect using the before, after and inbetween options, as shown in the commented \startitemize line. advTHANKSance >>>> MWE % Change spacing \setupwhitespace[big] \setupinterlinespace[3.8ex] \starttext \input ward \input ward \midaligned{% \setupTABLE[frame=off]% \setupTABLE[offset=1em]% \setupTABLE[r][each][topframe=on,bottomframe=on]% \setupTABLE[c][1][align={flushleft,high},width=1.5in]% \setupTABLE[c][2][align={flushleft,lohi},width=4.0in]% \bTABLE \bTABLEbody \bTR \bTD {\bf 2014--2015} \eTD \bTD \input ward \input ward \blank \input ward \eTD \eTR \bTR \bTD {\bf 2013--2014} \eTD \bTD \input ward % \startitemize[before={\blank[small]},after={\blank[small]},inbetween={\blank[medium]}] \startitemize \item Item one. \item Item two. \item Item three. \stopitemize \eTD \eTR \eTABLEbody \eTABLE } \stoptext <<<< -- ---- Pavneet Arora m: 647.406.6843 Waroc Informatik t: 416.937.9276

include path of modules
by Henning Hraban Ramm 16 Aug '15

16 Aug '15

Hi, I’m using Peter Münster’s downsampling module (http://modules.contextgarden.net/grph-downsample) and kept it under my project directory, like ~/mybook/tex/context/third/grph-downsample That worked with latest betas until 2015-07-31. It still works under .../texmf-local/tex/context/third/grph-downsample So there’s not really a problem, I can’t remember why I kept that project-local tree anyway, but something changed that might bite someone else...

Problem with the installation of a module
by Andrea De Michele 15 Aug '15

15 Aug '15

I tried to install the PocketDiary module but I had some problem. I follow the instruction at: http://wiki.contextgarden.net/Modules so first I copy the files in my texmf-local directory and after that I run: context --generate but context didn't find the new module. I use linux and I have installed texlive 2015 in my home directory, so my texmf-local directory is /home/admich/texlive/texmf-local In the output of context --generate I noticed the following lines: ... resolvers | resolving | locating list of 'home/admich/texlive/texmf-local' (cached) resolvers | methods | resolving, method 'locators', how 'uri', handler 'file', argument 'home/admich/texlive/texmf-local' resolvers | files | file locator 'home/admich/texlive/texmf-local' not found ... This seems not correct because is missing the initial / . For example the following lines are: resolvers | resolving | locating list of 'selfautoparent:texmf-dist' (cached) resolvers | methods | resolving, method 'locators', how 'uri', handler 'file', argument 'selfautoparent:texmf-dist' resolvers | files | file locator 'selfautoparent:texmf-dist' found as '/home/admich/texlive/2015/texmf-dist' resolvers | resolving | ... with the right initial / kpathsea find the right $TEXMFLOCAL: ~$ kpsewhich -var-value TEXMFLOCAL /home/admich/texlive/texmf-local -- Andrea De Michele

Cover page (Metafun)

Hi Hans, To progress in the use of Metafun, I try to do the same cover page as your document 'Metafun ". Without looking at the code (but using the definitions of your colors), I managed to get the mosaic. I would write the word "MATHÉMATIQUES" as you did with the word "CONTEXTEN".

Title of the section that begins

Hi, The first section begins, so the title appears footer on each page as the second section does not start. Then the second section starts and was the title of the second section as the third section does not start and so on. Thanks, Fabrice \setuppagenumbering [alternative=doublesided] \setupfootertexts[margin][][{\getmarking[chapter]}] \starttext \chapter{First} \section{one} \section{two} \chapter{Second} \section{one} \section{two} \stoptext
