Scientific paper boiler plate
by Kip Warner 15 Sep '14

15 Sep '14

Hey list, I'd like to write a short scientific paper describing an algorithm I discovered in the realm of computational geometry a few years ago before I forget it entirely. I've been meaning to do this for some time, but haven't had a chance. I'd like to use ConTeXt. Does anyone have a sample source I could take a look at as a starting point? I will need to typeset some figures, pseudo code, references, etc. and this all takes much less time when someone much more clever than I, like Wolfgang or Hans already has a similar environment file and such setup. Respectfully, -- Kip Warner -- Senior Software Engineer OpenPGP encrypted/signed mail preferred http://www.thevertigo.com

problem with buffer
by Kenny 15 Sep '14

15 Sep '14

I'm writing a module to typeset problems/tests. Depending on a flag, solutions are either displayed or not. If the solutions are not displayed, I want to give a certain amount of empty vertical space for the student's work. This is where my difficulty begins. The typesetting works with the solutions displayed (\def\examshowsolutions} {yes}) but not with the empty vertical space (\def\examshowsolutions{no}). I get an "Emergency stop" that I cannot figure out. Here's the code for a minimal example of my difficulty.. \def\setupsolutions{ \doifelse{\examshowsolutions}{yes} {\defineenumeration[SOLUTION] % display the solutions [text=\Word{solution},number=no, after={\vskip1ex}]} {\definebuffer[SOLUTION] % hide solutions, \setupbuffer[SOLUTION][local=yes]} } \def\startsolution{\dosingleempty\dostartsolution} \def\dostartsolution[#1]{ \getparameters[solution][height=1em,] % set defaults (needed in case parameters missing) \iffirstargument \writestatus{DEBUG}{--First argument: |#1|} \getparameters[solution][#1,] \fi \writestatus{DEBUG}{--\solutionheight--} \startSOLUTION \writestatus{DEBUG}{--dostartsolution...finished} } \def\stopsolution{ \stopSOLUTION \writestatus{DEBUG}{--dostopsolution...1} \doif{\examshowsolutions}{no}{\godown[\solutionheight]} \writestatus{DEBUG}{--dostopsolution...finished} } \starttext \def\examshowsolutions{no} % control whether solutions are displayed \setupsolutions \startsolution % test without vertical height specified Here is a solution. \stopsolution \startsolution[height=5em] % test with vertical height specified Here is another solution. \stopsolution \stoptext The error occurs with the \startSOLUTION command. Here's the log file: (/home/kenny/texlive/2013/texmf-dist/tex/context/base/cont-yes.mkiv ConTeXt ver: 2013.05.28 00:36 MKIV current fmt: 2013.8.6 int: english/english system > 'cont-new.mkiv' loaded (/home/kenny/texlive/2013/texmf-dist/tex/context/base/cont-new.mkiv) system > files > jobname 'check', input './check', result 'check' fonts > latin modern fonts are not preloaded languages > language 'en' is active (/home/kenny/courses/Fall2014/phys1310/exam/check.tex{/home/kenny/texlive/2 013/texmf-dist/fonts/map/pdftex/context/mkiv-base.map} fonts > preloading latin modern fonts (second stage) fonts > typescripts > unknown library 'loc' {/home/kenny/texlive/2013/texmf-dist/fonts/map/dvips/lm/lm-math.map} {/home/kenny/texlive/2013/texmf-dist/fonts/map/dvips/lm/lm-rm.map} fonts > 'fallback modern rm 12pt' is loaded DEBUG > --1em-- )) !

centering a makeup
by Pablo Rodriguez 14 Sep '14

14 Sep '14

Dear list, I have the following sample: \definemakeup [custom] [location=middle, width=.5\textwidth] \starttext \startmakeup [custom] \input ward \stopmakeup \stoptext How can I center the makeup in the page? \definemakeup[custom][align=middle] centers the lines, but this is something different. It is not a question of paragraph orientation. It is rather a question of placing the makeup in the middle of the page (also horizontally) Many thanks for your help, Pablo -- http://www.ousia.tk

Wrong page break in sequence of headings
by Jean-Philippe Rey 11 Sep '14

11 Sep '14

Dear all, I have a problem with page breaking in a sequence of titles (for example chapter, section, subsection) : a page break can occur between titles. I tested this with the last beta version ConTeXt ver: 2014.09.06 20:59 MKIV beta with the following example % ------------- Start of example ----------------------------- \setuphead[chapter][page=no] \starttext \chapter{Chap 1} \section{Bryson} \input bryson \section{Davis} \input davis \section{filler 1} Ipsam vero urbem Byzantiorum fuisse refertissimam atque ornatissimam signis quis ignorat? Quae illi, exhausti sumptibus bellisque maximis, cum omnis Mithridaticos impetus totumque Pontum armatum affervescentem in Asiam atque erumpentem, ore repulsum et cervicibus interclusum suis sustinerent, tum, inquam, Byzantii et postea signa illa et reliqua urbis ornanemta sanctissime custodita tenuerunt. Equitis Romani autem esse filium criminis loco poni ab accusatoribus neque his iudicantibus oportuit neque defendentibus nobis. Nam quod de pietate dixistis, est quidem ista nostra existimatio, sed iudicium certe parentis; quid nos opinemur, audietis ex iuratis; quid parentes sentiant, lacrimae matris incredibilisque maeror, squalor patris %et haec praesens maestitia, quam cernitis, luctusque declarat. Vita est illis semper %in fuga uxoresque mercenariae conductae ad tempus ex pacto atque, ut sit species %matrimonii, dotis nomine futura coniunx hastam et tabernaculum offert marito, %post statum diem si id elegerit discessura, et incredibile est quo ardore apud eos in %venerem uterque solvitur sexus. \chapter{Chap 2} \section{Dawkins} \input dawkins \section{Douglas} \input douglas \section{filler 2} Soleo saepe ante oculos ponere, idque libenter crebris usurpare sermonibus, omnis %nostrorum imperatorum, omnis exterarum gentium potentissimorumque populorum, %omnis clarissimorum regum res gestas, cum tuis nec contentionum magnitudine %nec numero proeliorum nec varietate regionum nec celeritate conficiendi nec %dissimilitudine bellorum posse conferri; nec vero disiunctissimas terras citius passibus %cuiusquam potuisse peragrari, quam tuis non dicam cursibus, sed victoriis lustratae sunt. \section{Group 1} \subsection{Hawking} \input hawking \subsection{Knuth} \input knuth \section{Linden} \input linden \stoptext % ------------- End of example ----------------------------- I get the "Chap 2" title at the end of the first page, it should be on top of the second page. Similarly the "Group 1" title is located at the bottom of the second page. I tried to use \startsection ... \stopsection but got the same result. Is there a setup to get the page breaks right ? Or is this a bug ?

Weird error
by Aditya Mahajan 10 Sep '14

10 Sep '14

Hi, There was a question on TeX.SX about an error message http://tex.stackexchange.com/questions/200474/setuppagenumberinglocation-ca… The following MWE shows the same error \setupfootertexts[\namedheadnumber{chapter}] \setuppagenumbering[location=,alternative=doublesided] \starttext \completecontent \chapter{Creating device driver} \section{How to create the} Chapter text \stoptext which gives lua error > error on line 8 in file /tmp/test.tex: ...uild/src/tex/texmf-context/tex/context/base/strc-doc.lua:904: attempt to index field 'numbers' (a nil value) stack traceback: ...uild/src/tex/texmf-context/tex/context/base/strc-doc.lua:904: in function 'getsectionnumber' [\directlua]:1: in main chunk The error is weird because it only appears when all parts of the minimal example are present. If I comment either or `location=,` or `alternative=doublesided` or `\completecontent` or `\section{...}`, the error goes away! Any thoughts? Aditya

Two errors in test file.
by john Culleton 09 Sep '14

09 Sep '14

Here is the test file: -------------------------------------- \definefontfamily [myfamily][serif][MinionPro Serif] \definefontfamily [myfamily][sans][MyriadPro Sans] \definefontfamily [myfamily][italic][MinionPro Italic] \setupbodyfont[myfamily] \starttext \rm foo \startitemize[a] \item {\bf Inkscape} \item Scribus \item Gimp \stopitemize \stoptext --------------------------------------- First, nothing prints. Second, if I say \startitemize[1] I get an error on the first \item line. I suspect that the default font doesn't have the big dot character. The system variable OSFONTDIR points to /usr/share/fonts Obviously there is something that I am missing in the font definitions. -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html PDF e-book: "Create Book Covers with Scribus" available at http://www.booklocker.com/books/4055.html

Separate italic font.
by john Culleton 06 Sep '14

06 Sep '14

Here is the example from the wiki -------------------------------------- \setupbodyfontenvironment[default][em=italic] \usemodule[simplefonts][size=10pt] \setmainfont[TeX Gyre Termes] \setsansfont[TeX Gyre Heros] \setmonofont[TeX Gyre Cursor] --------------------------------- If the font (e.g., MinionPro) has a separate italic font should I add it? If so is the correct command: \setitalicfont[\setupbodyfont[MinionPro-It] ??
