Table Numbering
by Malte Stien 18 Oct '12

18 Oct '12

Hello, I have just up just upgraded from version 2012.03.30 to the latest beta. Suddenly none of my tables are named chapter.number anymore, eg. Table 1.3 for the third table in Chapter 1, but just 3. That is, the chapter number is no longer prepended. Has something changed there? How can I enable the old behaviour again? Thank you, Malte. PS: The latest stable seems to still be 2011.05.18; any reason why that does not get updated?

ConTeXt unofficial test suite stub
by Marco Pessotto 18 Oct '12

18 Oct '12

Hello there! TL;DR: https://github.com/melmothx/context-unofficial-test-suite A week ago I had a conversation with mpfusion and another user over IRC about the ConTeXt test suite. mpfusion had a tarball with some test and an elaborate machinery to see if the testfiles compile. He kindly provided the tarball, and I took the liberty to do it my way (I didn't hear back from him, I assume he's working on his solution), using the testfiles and rewriting the code. My solution is quite simple, is written in perl (300 lines all included) and probably is not portable to non-unix machines. It uses imagemagick and pdftoppm to raster the PDF, and it's resonably fast (with a trick to speed up the difference parsing). It produces an ascii table like this: ./run-test.pl --run Using /usr/local/bin/context mtx-context | ConTeXt Process Management 0.52 mtx-context | mtx-context | main context file: /usr/local/texlive/2012/texmf-dist/tex/context/base/context.mkiv mtx-context | current version: 2012.05.30 11:26 ................. | File name | Success | Differs Avg | Worst value | Pages | Time | | arrows-001 | OK | 0.000000 | 0.000000 | 1 | 2 | | catcodes-001 | OK | 0.000000 | 0.000000 | 1 | 2 | | columnsets-001 | OK | 0.000000 | 0.000000 | 10 | 4 | | date-002 | OK | 0.000000 | 0.000000 | 1 | 2 | | dates-001 | OK | 0.605634 | 0.605634 | 1 | 2 | | dates-002 | OK | 0.000000 | 0.000000 | 1 | 3 | | hsv-001 | OK | 0.000000 | 0.000000 | 8 | 5 | | inclusion | OK | 0.000000 | 0.000000 | 1 | 2 | | metapost-001 | OK | 0.000000 | 0.000000 | 1 | 2 | | metapost-002 | OK | 0.000000 | 0.000000 | 1 | 2 | | mixed-001 | OK | 0.000000 | 0.000000 | 2 | 2 | | narrower-bidi-001 | OK | 0.000000 | 0.000000 | 4 | 2 | | ppchtex-001 | OK | 0.000000 | 0.000000 | 1 | 2 | | ppchtex-005 | OK | 0.000000 | 0.000000 | 1 | 2 | | ppchtex-006 | OK | 0.000000 | 0.000000 | 1 | 2 | | spot-001 | OK | 0.000000 | 0.000000 | 1 | 3 | | tables-001 | OK | 0.000000 | 0.000000 | 1 | 1 | It leaves the visual diffs as png images under diffs/ I'd like to know if there is some interest in this thing, as (obviously) the test suit is not really populated to have any kind of value. There is also room for improvement (like custom arguments to the compilation). Happy euroTeXt to the lucky partecipants. Enjoy! Best wishes -- Marco

[co-pagedesign.tex] grid=yes not mentioned

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
