Natural Tables in multiple columns
by Jannik Voges 25 Dec '12

25 Dec '12

Hello ConTeXt-Users, I get a strange behavior (latest beta), when I try to typeset natural tables and normal text in multiple columns. When I type normal text into a column and add a natural table which total length is small enough to fit into the column, the table is placed into the column with the text. When the total length is too large, the table starts in the next column and leaves the rest of the column empty (of course I used split=yes). I would expect that the table starts in the column with the text and is split properly. Minimal example: small table \starttext \startcolumns[n=3] \dorecurse{10}{Test\crlf} \bTABLE[split=yes] \dorecurse{10} {\bTR \bTD a\eTD \bTD b \eTD \eTR} \eTABLE \stopcolumns \stoptext large table \starttext \startcolumns[n=3] \dorecurse{10}{Test\crlf} \bTABLE[split=yes] \dorecurse{20} {\bTR \bTD a\eTD \bTD b \eTD \eTR} \eTABLE \stopcolumns \stoptext

to pass an argument in a macro
by Roland Thiers 25 Dec '12

25 Dec '12

Bonjour, I am new in ConTeXt. I love its features. I need some (or a lot of) help. I tried to get a macro which compute some values for a math function. With help from the wiki ConTeXt Garden and some time I could do that - write my function userdata.f - write another function to put the values in a table : userdata.tabf - put both of them in a file "/Users/rolandt/context/mesfonctionsluatex.lua" - In a file.tex, I use that macro : \def\tabf#1#2% {\startluacode dofile("/Users/rolandt/context/mesfonctionsluatex.lua") userdata.tabf(#1,#2) \stopluacode} Here are the functions: -- fonction cube -- on utilise l'espace de nom userdata userdata=userdata or {} function userdata.f(x) context(x*x*x) end -- fonction tabf -- which makes a table , compute 6 values, b=first x, c = step userdata=userdata or {} function userdata.tabf(b,c) context.starttable{"*{7}{|l}|"} local b=b local c=c context("\\HL") context("\\VL x ") for i=1,6 do context("\\NC" .. b+(i-1)*c) end context("\\VL".."\\AR") context("\\HL") context("\\VL f(x) ") for i=1,6 do context("\\NC") context(userdata.f(b+(i-1)*c)) end context("\\VL".."\\LR") context("\\HL") context.stoptable() end I am sure it could be much better but it works ! Evidently I need a third argument to be able to choose how many values compute. I failed completely (I don't understand how arguments are passed). I tried things like : context.starttable{"*{%s}{|l}|",a} but ... fatal error :) I would appreciate some help or what to read to improve understanding that kind of things. Best regards, Roland

Help with installation
by Michal Kvasnička 25 Dec '12

25 Dec '12

Hallo. I'm sorry to bother you this time but I would really apprecitate your help. I've installed Ubuntu 12.10 64 bit on a new disk. I downloaded the last stable version of ConTeXt suite (today). The installation was all right. However, when I run texexec (e.g. texexec --help), I get the following error: /programy/context/tex/texmf-linux-64/bin/mtxrun:15228: attempt to index field 'loaders' (a nil value) The same happens with context (e.g. context --help). Can you tell me what to do? I guess I simply need to install some libraries. This is the first time I've tried 64 bit Ubuntu. Best wishes Michal

Odd /externalfigure behavior
by Guy Stalnaker 21 Dec '12

21 Dec '12

All, I've been working on a document for weeks and it's been compiling fine. I have a pdf copy from yesterday afternoon at 4p local time, the last time it compiled successfully. I was doing a search/replace on some /crlf to add space between text and an image. The search/replace with Gnome's gedit included \n in both search and replace string. Suddenly context will no longer successfully compile the document! What's very, very odd, is that the context document is an output file from pandoc of a markdown document that has had no issues until now. If I go back now to the original markdown doc and regenerate the context document the issue persists with or without subsequent edit!! Damned peculiar. Here's the workflow: pandoc -s -f markdown -t context <file.md> -o <file.context.tex> gedit <file.context.tex> to add: \defineexternalfigure[screenshot][frame=on] and then add [screenshot] to all of the \externalfigure directives. Then find the /crlf that appear immediate before *all* of the \externalfigure directives and double them (unless someone who reads this can tell me how to easily modify the padding of an image when it's placed to increase the spacing between the image and the text above it). I've been doing this for many days. Until late yesterday afternoon. Now context spits out this: <quote> structure > sectioning > subsubsubsection @ level 6 : 0.0.0.1.3.1 -> One URL for All Projects !

I can successfully use display from the commandline in the same dir as the context file on that path shown in the quoted output and it opens the image. So, it's not the image file or the path--they are both fine. Any ideas anyone? -- "There is only love, and then oblivion. Love is all we have to set against hatred."

problems with units
by Andreas Mang 21 Dec '12

21 Dec '12

Hi there, I encountered some problems with the built in units command in MKIV. I provide a minimal example which should demonstrate my problems. Maybe I am doing something wrong... Cheers, Andreas %%%%%MINIMAL EXAMPLE%%%%% \setupbodyfont[pagella] \starttext % this is just my default setting - if I comment the next line I get the same behaviour \setupunits[method=3,order=reverse,separator=small] \unit{11,1e-1 micro mol per second} \par %no effect if I change the separator (holds also for cdot) $\unit{11,1e-1 micro mol per second}$ \par %wrong spacing \unit{11,1e-1 per second} \par % one over is not working (no unit displayed) \unit{11,1e-1 / second} \par % one over not working (no unit displayed) \stoptext %%%%%MINIMAL EXAMPLE%%%%%

Balanced parenthesis.
by Andre Caldas 20 Dec '12

20 Dec '12

Instead of writing $\left( x+y \right)$, I'd like to simply write $(x + y)$. For unmatched parenthesis, I would like to write $:-\unmatched)$. How can I accomplish that in context? Cheeers, André Caldas.

Is there a way to for ConTeXt to do basic arithmetic operations? For example, \calc{1+2} and have it return 3 or \calc{1/3.8} and have it return 0.263157894736842 (or rounded) Troy
