startnarrower and framed?
by Jon Wong 21 Aug '19

21 Aug '19

Hi all, I want to have a \startnarrower effect. But I also want that segment to have a border (hopefully a gradient background color too!). I tried: \startnarrower \framed{testing} Seems framed doesn’t observe startnarrower commands. \endnarrower How do I achieve that? Regards Jon

Re: [NTG-context] LMTX: Space in file names

Hi Hans, Thanks to your reply, I just discovered the reason for which I could not typeset in lmtx files which have a space in their name from the Terminal: one has to say context "exercice 1.tex" that is to enclose the entire filename between double quotes… Which is completely logical! Thanks a lot for your time!

balanced vertical spaces under \startcolumnset
by Jeong Dal 20 Aug '19

20 Aug '19

Dear all, I use the following code to make test. To make the same height blank spaces after the problems, I use \vfill before \column. The problem is that the second \column creates extra blank page. But, without the second \column, the height of blank spaces of the second column are different. Is there a way to make the blank spaces height same while not to create a blank page? Thank you for reading.

Trouble with lmtx install.bat
by Joseph Canedo 20 Aug '19

20 Aug '19

Dear list, It seems that sometimes incremental install.bat (ie run without wiping out the whole lmtx directory) does not work the same as full installation (ie wiping out the whole directory and reinstalling). I’ve ran install.bat first time this morning and I got the following error during installation tex error > tex error on line 137 in file page-txt.mklx: ! Undefined control sequence <argument> \c!middlestyle \mult_interfaces_get_parameters_item ...ty \fi #2 <argument> ...youtelementparameter \c!style , \c!middlestyle =\layoutelementparameter \... \mult_interfaces_get_parameters_indeed ..._item #1 ,], \setup_layoutelement ...ers {\??layouttexts :}[#1] \the \everysetuplayoutelem... <to be read again> \syst_helpers_double_empty_two_nop \par l.137 <empty file> Deleting the lmtx directory entirely and reinstalling from scratch succeeded (ie without above error), but I thought install.bat was able to update the files without need of erasing everything before ? Thanks Joseph

LMTX: Space in file names
by Otared Kavian 20 Aug '19

20 Aug '19

Hi Hans, I noticed that the lmtx beta from 2019.08.18 22:27 does not anymore accept spaces in file names, while the mkiv version does accept it. I am aware that putting a space in a file name is a very bad habit, but I am convincing some people who were used to use MS Word in order for them to use ConTeXt, and these people have many files with names containing spaces such as « correction problème 1.tex » (and in fact this is how I noticed this new behavior of lmtx: when typesetting such a file, lmtx looks for « correction.tex »). That is why I think if lmtx could continue to accept spaces in file names that would be very convenient. Do you think this would be possible? Best regards: OK

What I have in mind (others could complete) is in particular a way to plot the set of (x,y) such that f(x,y)=0 for some given function f and some rectangle in x and y. I made some plots with Mathematica http://www.maths.lth.se/matematiklth/personal/mickep/Contour.pdf (too big for the list) The first plot shows a difficulty with a contour plot, namely intersections. In the second one I added points, and it looks better. In the third plot I have not specified that the expression should be equal to 0. Then Mathematica plots the curves f(x,y)=C for various values of C. In the background it adds a density plot (i.e. a mesh with different colours for different values of the function. In the fourth plot, the regionplot, the pairs (x,y) for which f(x,y)<0 are marked. This is also very useful. In the fifth plot there is only the densityplot, with different colors for different values of f. I don't know how difficult it is to implement this kind of graphics. Also, it could be useful to be able to input the equation f(x,y)=0 and to receive the curves as MetaPost paths. It seems that one can do contour plots with the help of lua if that is something that helps ( http://franko.github.io/graph-toolkit/contour.html) Anything would be better than nothing, and I'm more than happy to test. > > > 3) (small) The possibility to have arrows in coordinate axes.

\setupcolumnsetlines does not work again
by Sytse Knypstra 19 Aug '19

19 Aug '19

I thought I understood the mechanism, but I found another instance where \setupcolumnsetlines does not give the desired result: %%%%%%%%%%% \definecolumnset[Two][n=2] \starttext Test %\page \setupcolumnsetlines[Two][1][1][9] \startcolumnset[Two] \input knuth \stopcolumnset \setupcolumnsetlines[Two][1][1][9] \startcolumnset[Two] \input knuth \stopcolumnset \stoptext %%%%%%%%%%% This setup gives indeed a balanced first page and an unbalanced second page. But if the fourth line (\page) is uncommented, the second output page is unbalanced and the third page is balanced. So the mechanism is therefore more complicated than > only if the first columnset extends to more than one page > the next \setupcolumnsetlines will work properly. What is the extended rule? If this intended behaviour, what is the reason behind it?

Bug in lmtx with \Bbb
by Otared Kavian 19 Aug '19

19 Aug '19

Hi Hans, It seems that there is a bug in the handling of Blackboard Bold, in the latest lmtx (version 2019.08.02 19:40). The following gives the attached PDF file. However the same file typesets correctly in the latest mkiv beta. Thanks for your attention: OK \starttext The set of integers is denoted ${\Bbb N}$. \stoptext
