Re: [NTG-context] making tables with lua

Dear Proch?zka Luk?? Ing and Hans, Thank you for the reply. It works fine. I modify your code to write a matrix and it also works too. \startformula \startluacode local NC, NR = context.NC, context.NR local t = {{1,0,3,4},{0,2,-2,5},{0,0,1,2}} context.startmatrix() --"{left={\left (\,},right={\,\right)}}") for _, r in ipairs(t) do for _, c in ipairs(r) do NC() context(c) end NR() end context.stopmatrix() \stopluacode \stopformula But I couldn't put "( )" before and after matrix. If I use context.startmatrix("{left={\left (\,},right={\,\right)}}") then it wrote "left…" as text before the matrix. How to enclose matrix with ( )? Thank you again. Best regards, Dalyoung > 4.

making tables with lua
by Jeong Dal 17 Oct '12

17 Oct '12

Dear all, I used code which generates the table as following: \startluacode local NC, NR, HL, VL = context.NC, context.NR, context.HL, context.VL context.starttabulate { "|c|c|c|c|c|c|c|c|c|c|" } HL() for i=1, 6, 1 do for j=1,10 ,1 do k= i % 3 if k==1 then VL() context(10*(i - k)/3+j) else VL() end end VL() NR() if k==0 then HL() end end context.stoptabulate() \stopluacode But it has a fixed column definition as "|c|c|c|c|c|c|c|c|c|c|" and the number of columns. I wonder it is possible to use the variable for "j" to control the number of columns and the column setting. Of course, I may put similar codes which are different only in the number of columns and column settings when I need a table. But I have many similar tables whose number of columns are different only. If such a method is possible, I'd like to put such a code in \startbuffer…\stopbudffer and call it to generate tables of various number of columns given at each time. I also don't know whether it is possible to convey a number from ConTeXt to the variable in Lua code. I write this email because I saw a hope in recent discussion "Re: Fwd: Need help with \definetabulate" which has a method to vary the column setting. \definetabulate [whatever] [|l|r|] \definetabulate [whatever][else] [|l|c|r|] It may be a lazy man's question with no need for others. Thank you for reading. Best regards, Dalyoung

Re: [NTG-context] Need help with \definetabulate
by Malte Stien 17 Oct '12

17 Oct '12

Marco, > \definetabulate [alpha] [|l|l|l|] > \setuptabulate [alpha] [bodyfont=small] This does not work for me quite the way I need it to. I am really just after defining the font-size, but I would like to leave the column setup to the user (I am building an environment and that I would like everyone in my team to use to ensure a consistent look-and-feel or all documents). So, ideally, I would like to do this: > \definetabulate [alpha] > \setuptabulate [alpha] [bodyfont=small] > \starttext[|l|l|l|] > \startalpha > \NC first \NC second \NC third \NC\NR > \stopalpha > \stoptext ...but that does not seem to work. Any way I can achieve this? > Feel free to add an example. It's a wiki! Sure. Will do, once I have this working.

scale=... and specifying the width and height of a figure
by Aditya Mahajan 16 Oct '12

16 Oct '12

Hi, If scale option for a figure is set, \externalfigure does not honor the width and the height parameters. For example \externalfigure[cow][width=1cm, height=3cm, scale=750] gives a figure which has the usual aspect ratio. I know that settings scale=... along with width and height does not make sense. But, in one of my project, I set \setupexternalfigures[scale=750] as that makes sense for most of the figures, and if I try to use \externalfigure[cow][width=1cm, height=3cm] then the aspect ratio of the figures does not change. Not sure if this should be classified as a bug, but I am posting it here in case anyone else encounters the same issue and needs to know how to override this behavior: \externalfigure[cow][width=1cm, height=3cm, scale=] Aditya

Total Number of Pages
by Nicholas Ulle 16 Oct '12

16 Oct '12

Hi, How would I go about inserting the total number of pages in my document? I assume this would require two passes of texec or context. I've tried Googling and checking ConTeXt garden, but couldn't find anything regarding this. Thanks again, Nick

Subscript Depth
by Nicholas Ulle 16 Oct '12

16 Oct '12

Hi, How would I go about getting subscripts to stay at the same depth? An example of the problem I'm having is: \starttext % Notice the b's are not aligned $a_b' a_b$ \stoptext I'm only just learning ConTeXt and TeX, so I'm not sure what I'd need to change to fix this. Thanks, Nick

New module: pararef
by Zenlima 16 Oct '12

16 Oct '12

Hallo, after so many of you helped me, I want to give back. I just made my t-pararef module public for everyone: http://modules.contextgarden.net/pararef http://wiki.contextgarden.net/Paragraph_Referencing Please feel free to send me comments about the coding style and what I could have done in a better way. E.g. the interface file is missing, but I don't know how it should look like. But I hope mainly that it will prove beneficial for some of you. H.

Vertical positioning of floats within itemize
by Marcin Borkowski 16 Oct '12

16 Oct '12

It's me again! This doesn't quite work as expected (at least by me, that is;)): \starttext \startitemize \startitem \placefigure[right,high,none]{}{\framed[width=3cm,height=2cm]{!}} \input knuth \stopitem \stopitemize \stoptext (Namely, at the beginning of the \item there is something like a "blank line".) If I move \placefigure before \startitem, it looks better, but this seems to be a nasty hack. Do you have any idea how to achieve this effect in a more elegant way? TIA, -- Marcin Borkowski http://octd.wmi.amu.edu.pl/en/Marcin_Borkowski Adam Mickiewicz University

ConTeXt inputs files from TEXMF/doc
by Mojca Miklavec 16 Oct '12

16 Oct '12

Hello, I used \externalfigure[background] in a document (and I forgot to compile the local file background.tex) and ended up with a pleasant surprise: the command included /usr/local/texlive/2012/texmf-dist/doc/latex/background/background.pdf instead of complaining that the file doesn't exist. Shouldn't ConTeXt prevent inclusion of documents from "doc"? Mojca PS: tested with ConTeXt from TeX Live (as is probably evident from the fact that the file from TL has been found).
