\setuplayout question
by Marcin Borkowski 28 Oct '12

28 Oct '12

Hello, what is the *default* layout? (I am especially interested in bottomspace - in page-lay.mkiv I found bottomspace=0pt, but this seems not to be the case - even after \setupfooter[state=stop] text does not go to the bottom of the sheet. Which parameter is responsible for that? Regards, -- Marcin Borkowski http://octd.wmi.amu.edu.pl/en/Marcin_Borkowski Adam Mickiewicz University

Problems with sectionreset key for \setuphead
by Wolfgang Schuster 28 Oct '12

28 Oct '12

Hi Hans, there are a few problems with the sectionreset key for \setuphead. In the example below I can only create continues numbers for \section when I “default” as name for \defineresetset (Method 1) or when I apply my own set to the global setups (Method 2). The important second method which is needed when I have multiple headings with the same level where one should continue to the while document doesn’t work. % Method 1: % \defineresetset[default][][0] % Method 2: % \defineresetset[noreset][][0] % \setuphead[section][sectionresetset=noreset] % Method 3: \defineresetset[noreset][][0] \setuphead[sectionresetset=noreset] \starttext \chapter{First Chapter} \section{First Section} \chapter{Second Chapter} \section{Second Section} \stoptext Wolfgang

How to set the whole document flush left?
by Marcin Borkowski 27 Oct '12

27 Oct '12

Hi, I'd like to have all my document set flush left. I know how to set a \framed flush left, or \startalign ... \stopalign - but what about the whole? (In my current case, the document is basically a (mid-aligned) title and then one big itemgroup, so I added [align={right,broad}] to the \startitemize - but what about the general case? \raggedright did not work, at least for the itemization.) Best, -- Marcin Borkowski http://octd.wmi.amu.edu.pl/en/Marcin_Borkowski Adam Mickiewicz University

The on-going process of the Proceedings for Context Meeting 2011
by John Haltiwanger 27 Oct '12

27 Oct '12

Hello all! It's been very quiet in regards to the Context Group's first publication, the Proceedings for Context Meeting 2011. We've been hammering out the details of a new design and house style with Adrian Egger. This process is almost complete, and we are very excited for you all to see the inspiring new design! But there is, of course, the issue of getting the final content together for this issue. And here is where I need the help of those who agreed at last year's meeting to submit an article for the proceedings: We would like to publish this years proceedings along with last years in a double edition. I've lost the list of those who wanted to submit last year, so if you remember being one of those nice and awesome people, please consider writing up a short article and sending it! *Of course we also welcome any Context-related articles! *There has been a lot of cool stuff happening in the community over the last year, and it would be great to have some further documentation on them. A very warm thanks to those of you who sent me material already--know that it was not in vain, and that your work will indeed be published. The *deadline for submission is 1 November*, with the double-edition proceedings landing on doorsteps in time for the winter holidays. For those of you who have not yet joined the Context Group, please consider doing so<http://group.contextgarden.net/register.shtml> ! Looking forward to hearing from you, John

Math Overruns Background
by Nicholas Ulle 26 Oct '12

26 Oct '12

Hello, I'm trying to typeset an exam with solutions in framed or shaded boxes, using \background. However, the background doesn't stretch to the bottom of the text area when there is text preceding it, so if there is enough math inside the background, the math overruns its lower bound. How can I get everything to stay inside the background? A minimal example: \starttext \input knuth \startbackground \input knuth \dorecurse{20}{\startformula \sum_{i=0}^5 i \stopformula} \stopbackground \stoptext I've tried some of the options in \setupbackground with no luck, and have also tried Googling for an answer. Thanks, Nick

defineindenting

Hello list, I feel a bit "out of context" not following the list closely for some time so maybe this has been solved already. I cannot get defineindenting to work. Example attached. Best Piotr -- http://okle.pl

Re: [NTG-context] using variable for subscript in math+lua
by Jeong Dal 26 Oct '12

26 Oct '12

Thanks to all who gave a nice solutions. To write a big matrix of unknowns A=(a_{ij}) is not a frequent case. In math, there are many occasions to write matrices which need some typing work like \NC 2 \NC 3 \NC 4 \NR So if we have a function which write a matrix when the data is given as a form of table in Lua. There are other benefits. Sometimes, we may have to write a series matrices which are the results of the some row operations in matrix. We can also handle it conveniently because we can do some calculations in Lua. If there is a way to convey some table data from ConTeXt to Lua, it would be more convenient. Here is an example which I did by your help. I hope that you experts can make it more useful. Thank you again. Best regards, Dalyoung \starttext \startluacode matrixfunction = matrixfunction or {} -- recommended: use namespace matrixfunction.print_matrixA = function () context.startmatrix{left = "\\left(\\,", right = "\\,\\right)"} local schema1 = "a_{%d%d}" -- %d: prints integer part local schema2 = "a_{%d%s}" local schema3 = "a_{%s%d}" for i=1, 3 do for j=1, 3 do context.NC() context(schema1, i, j) end context.NC() context("\\cdots") context.NC() context(schema2, i, "n") context.NR() end for j = 1, 3 do context.NC() context("\\vdots") end context.NC() context("\\ddots") context.NC() context("\\vdots") context.NR() for i=1, 3 do context.NC() context(schema3, "m", i) end context.NC() context("\\cdots") context.NC() context("a_{mn}") context.NR() context.stopmatrix() end matrixfunction.print_matrix = function (t) context.startmatrix{left = "\\left(\\,", right = "\\,\\right)"} for _, r in ipairs(t) do for _, c in ipairs(r) do context.NC(c) end context.NR() end context.stopmatrix() end matrixfunction.rowChange = function(t, i, j) -- interchange two rows(i-th, j-th) t[i] , t[j]= t[j], t[i] end matrixfunction.rowMult = function(t, i, m) -- replace i-th row with m*(i-th row) local len len = #(t[i]) for k = 1, len do t[i][k] = m*t[i][k] end end matrixfunction.rowMultSum = function(t, i, j, m) -- replace i-th row with i-th row + m*(j-th row) local len len = #(t[1]) for k = 1, len do t[i][k] = t[i][k] + m*t[j][k] end end \stopluacode \startformula\startluacode matrixfunction.print_matrixA() \stopluacode\stopformula \startformula\startalign \startluacode local mat = {{0, 2, 4, -4, 1},{0, 0, 2, 3 , 4}, {2, 2, -6, 2, 4 }, {2,0 , -6, 9, 7}} context.NC("\\text{Given matrix}\\quad\\Rightarrow\\quad") context.NC() matrixfunction.print_matrix(mat) context.NR() context.NC() context("{\\bf r}_1 \\leftrightarrow {\\bf r}_3 \\quad\\Rightarrow\\quad") matrixfunction.rowChange(mat, 1, 3) context.NC() matrixfunction.print_matrix(mat) context.NR() context.NC() context("\\frac{1}{2}{\\bf r}_1 \\rightarrow {\\bf r}_1 \\quad\\Rightarrow\\quad") matrixfunction.rowMult(mat, 1, 1/2) context.NC() matrixfunction.print_matrix(mat) context.NR() context.NC() context("-2{\\bf r}_1 + {\\bf r}_4 \\rightarrow {\\bf r}_4 \\quad\\Rightarrow\\quad") matrixfunction.rowMultSum(mat, 4, 1, -2) context.NC() matrixfunction.print_matrix(mat) context.NR() context.NC() context("{\\bf r}_2 \\leftrightarrow {\\bf r}_3 \\quad\\Rightarrow\\quad") matrixfunction.rowChange(mat, 2, 3) context.NC() matrixfunction.print_matrix(mat) context.NR() \stopluacode \stopalign\stopformula \stoptext

A problem with \blank
by Marcin Borkowski 26 Oct '12

26 Oct '12

Good evening, I have something like this in my document: \startalignment[middle] ... \stopalignment \startitemize ... \stopitemize and I want some (more) vertical space in between them. Adding a \blank[big] (and even a \blank[big,force]) didn't help. Interestingly, \leavevmode\blank[big] did. What is going on? What is the "canonical" way to achieve what I want to have?
