calling up chapter title
by Hans van der Meer 26 Apr '19

26 Apr '19

This does not what I have in mind: \setupheadertexts[text][chapter][\pagenumber chapter][pagenumber][chapter] Instead of [\pagenumber chapter] I thought [\pagenumber \chapter] would give me in the header both the pagenumber and the recorded chapter title. However \chapter turns out to be undefined, neither did \chaptertitle. What is the macro to be called? dr. Hans van der Meer

how to call chapter title and chapter number

adjusting tikz pictures
by Gour 26 Apr '19

26 Apr '19

Hello, I believe that using GeoGebra for drawing, exporting to TikZ is the most approachable method for me to be able to create mathematic-related material like exams for the children in the primary school, but need some info how to adjust GeoGebra's TikZ output (suitable for LaTeX) for ConTeXt? The link on the wiki's page (https://wiki.contextgarden.net/TikZ) ﬁor the manual is dead.. Here is the simple example: \documentclass[10pt]{article} \usepackage{pgf,tikz,pgfplots} \pgfplotsset{compat=1.15} \usepackage{mathrsfs} \usetikzlibrary{arrows} \pagestyle{empty} \begin{document} \definecolor{zzttqq}{rgb}{0.6,0.2,0} \definecolor{ududff}{rgb}{0.30196078431372547,0.30196078431372547,1} \begin{tikzpicture}[line cap=round,line join=round,>=triangle 45,x=1cm,y=1cm] \begin{axis}[ x=1cm,y=1cm, axis lines=middle, ymajorgrids=true, xmajorgrids=true, xmin=-12.679999999999998, xmax=12.679999999999998, ymin=-13.470000000000002, ymax=8.91, xtick={-12,-11,...,12}, ytick={-13,-12,...,8},] \clip(-12.68,-13.47) rectangle (12.68,8.91); \fill[line width=2pt,color=zzttqq,fill=zzttqq,fill opacity=0.10000000149011612] (-7.7,2.75) -- (0.88,2.57) -- (-3.04,-3.37) -- cycle; \draw [line width=2pt,color=zzttqq] (-7.7,2.75)-- (0.88,2.57); \draw [line width=2pt,color=zzttqq] (0.88,2.57)-- (-3.04,-3.37); \draw [line width=2pt,color=zzttqq] (-3.04,-3.37)-- (-7.7,2.75); \draw [line width=2pt,domain=-12.68:12.68] plot(\x,{(--25.3932-4.84*\x)/0.04}); \draw [line width=2pt,domain=-12.68:12.68] plot(\x,{(-13.78-3.92*\x)/5.94}); \draw [line width=2pt,domain=-12.68:12.68] plot(\x,{(--29.7366--8.58*\x)/0.18}); \begin{scriptsize} \draw [fill=ududff] (-7.7,2.75) circle (2.5pt); \draw[color=ududff] (-7.54,3.18) node {$A$}; \draw [fill=ududff] (0.88,2.57) circle (2.5pt); \draw[color=ududff] (1.04,3) node {$B$}; \draw [fill=ududff] (-3.04,-3.37) circle (2.5pt); \draw[color=ududff] (-2.88,-2.94) node {$C$}; \draw[color=zzttqq] (-3.34,2.58) node {$c$}; \draw[color=zzttqq] (-1.28,0.02) node {$a$}; \draw[color=zzttqq] (-5.04,0.12) node {$b$}; \draw [fill=ududff] (5.2,5.63) circle (2.5pt); \draw[color=ududff] (5.36,6.06) node {$D$}; \draw [fill=ududff] (5.24,0.79) circle (2.5pt); \draw[color=ududff] (5.4,1.22) node {$E$}; \draw[color=black] (4.92,8.82) node {$f$}; \draw [fill=ududff] (-2,-1) circle (2.5pt); \draw[color=ududff] (-1.84,-0.56) node {$F$}; \draw[color=black] (-12.5,5.84) node {$g$}; \draw[color=black] (-3.04,8.82) node {$h$}; \end{scriptsize} \end{axis} \end{tikzpicture} \end{document} How would such example be adjusted to be used with ConTeXt? Sincerely, Gour -- As the embodied soul continuously passes, in this body, from boyhood to youth to old age, the soul similarly passes into another body at death. A sober person is not bewildered by such a change.

tikz is not found
by Gour 25 Apr '19

25 Apr '19

Hello, in order to try using TikZ figures (exported from Geogebra) I tried with some simple TikZ example with lmtx install, but I get the following: system > ConTeXt ver: 2019.04.16 09:07 MKIV beta fmt: 2019.4.23 int: english/english system > system > 'cont-new.mkiv' loaded open source > level 2, order 2, name '/home/gour/opt/lmtx/tex/texmf-context/tex/context/base/mkiv/cont-new.mkiv' system > beware: some patches loaded from cont-new.mkiv close source > level 2, order 2, name '/home/gour/opt/lmtx/tex/texmf-context/tex/context/base/mkiv/cont-new.mkiv' system > files > jobname 'tik', input './tik', result 'tik' fonts > latin modern fonts are not preloaded languages > language 'en' is active open source > level 2, order 3, name > '/home/gour/prj/tex/tik.tex' colors > 'rgb' color space is > supported colors > 'cmyk' color space is supported modules > 'tikz' is not found [...] so wonder how to add missing tikz module? I'm running Devuan (Debian) 'testing' (x86-64)... Sincerely, Gour -- From anger, complete delusion arises, and from delusion bewilderment of memory. When memory is bewildered, intelligence is lost, and when intelligence is lost one falls down again into the material pool.

ConTeXt has to update the number of remaining lines for side floats at the begin each each paragraph but when you start a paragraph in a group, e.g. {\bf ...} to information is lost after the closing brace. When you add now \dontleavehmode before the group starts you flushed to information because the paragraph already started. Wolfgang

Formula number misplaced
by Henri Menke 24 Apr '19

24 Apr '19

Dear list, The problem I describe does not make itself apparent in all situations, but sometimes the formula number, which is placed by \start...\stopplaceformula, is misplaced and there appears a gap between it and the right margin. The MWE below reproduces the problem in the latest beta and lmtx. It can be "fixed", however, by replacing \start...\stopTEXpage by \start...\stoptext, so this might not represent the most generic incarnation. Cheers, Henri --- \startTEXpage \samplefile{ward} Thus \startplaceformula \startformula \int_a^b f(x) \, \diff x = F(b) - F(a) . \stopformula \stopplaceformula \stopTEXpage

preparing math exams
by Gour 24 Apr '19

24 Apr '19

Hello, I wonder what would be recommended way to prepare math exams for primary school (e.g. 5th to 8th grade) which involves drawing lines, segments, angles, polygons, circles, drawing functions etc.? For regular formulas involving e.g. rational numbers, I'm sure that input language for math is quite sufficient, but wonder about drawing part? Sincerely, Gour -- A person who is not disturbed by the incessant flow of desires — that enter like rivers into the ocean, which is ever being filled but is always still — can alone achieve peace, and not the man who strives to satisfy such desires.

mathalign: specifying distance with glue
by Aditya Mahajan 23 Apr '19

23 Apr '19

Hi, amsmath provides an environment `flalign` that flushes the "block" for display math. See page 6 (pdf page 27) of my article on display math in context (https://www.ntg.nl/maps/34/06.pdf) for an example. As shown in that article, I could achieve the same behavior in context mathalign by using distance=2em plus 1fil. However, on a recent context, the glue gets ignored. \starttext \startformula \startmathalignment[m=2,distance=2em plus 1 filll]%Notice distance=... \NC \nabla\cdot \bf E \NC= \frac{\rho}{\varepsilon_0}, \NC \nabla\times \bf E \NC= -\frac{\partial \bf B}{\partial t}, \NR \NC \nabla\cdot \bf B \NC= 0, \NC \nabla\times \bf B \NC= \mu_0{\bf j}+\varepsilon_0\mu_0 \frac{\partial \bf E}{\partial t}. \NR \stopmathalignment \stopformula \stoptext Looking at math-ali, I cannot figure out why that is happening.
