Hi, trying to update (running standalone, updating with sh ./first-setup.sh --update it runs for a while, and then halts on: lua error > lua error on line 74 in file /home/mickep/ConTeXt/tex/texmf-context/tex/context/base/mkiv/node-rul.mkiv: ...eXt/tex/texmf-context/tex/context/base/mkiv/node-rul.lua:369: table index is nil stack traceback: ...eXt/tex/texmf-context/tex/context/base/mkiv/node-rul.lua:369: in function 'code' ...eXt/tex/texmf-context/tex/context/base/mkiv/util-lua.lua:84: in function 'loadedluacode' ...eXt/tex/texmf-context/tex/context/base/mkiv/luat-env.lua:104: in function 'luafilechunk' ...eXt/tex/texmf-context/tex/context/base/mkiv/luat-cod.lua:45: in function 'registercode' [ctxlua]:1: in main chunk 64 %D to deal with local settings at the \TEX\ end and remembering parameters 65 %D at the \LUA\ end.

page range reference (how to compare references)
by MF 23 Sep '16

23 Sep '16

Hello list, I'm trying to reference a page range (think of a long quote spanning on 2 pages). I need to discriminate ranges collapsing to one page from "real" ranges (2 or more pages): "1-1" should become "1", while "1-2" should stay like that. Here's a not working snippet: \starttext Tufte quote at p. \at[tufte:start]\doifelse{\ref[realpage][tufte:start]}{\ref[realpage][t ufte:stop]} {} {-\at[tufte:stop]} % start of quote reference \pagereference[tufte:start] \input{tufte} %\page % comment/uncomment this to toggle from range to single page \input{tufte} % end of quote reference \pagereference[tufte:stop] \stoptext The \doifelse is always false, I think because \ref[realpage][...] is not a string. Thanks in advance. BTW, best wishes for next week's meeting (hoping to join next year). Best regards, Massi

Size of the last shipped page by Lua?
by Procházka Lukáš Ing. 23 Sep '16

23 Sep '16

Hello, is there a way to detect by Lua what is the size (width and height) of the last shipped page? Especially I'm interested in the situation when page via \start/\stopTEXpage has been shipped, like: ---- \startluacode LastPageSize = function() -- What to come here? return w, h end \stopluacode \starttext \startluacode local w, h = LastPageSize() context("w="..w .. ", h=" ..h) -- Should give "w=210mm, h=297mm" (or other units) \stopluacode \startTEXpage[with=10cm,height=15cm] \stopTEXpage \startluacode local w, h = LastPageSize() context("w="..w .. ", h=" ..h) -- Should give "w=100mm, h=150mm" (or other units) \stopluacode \stoptext ---- This would be very useful when I need to insert a page of size of the last page to move to odd page when A4 and A3 pages are mixed, to allow simple duplex printing on the printer. So - how about 'LastPageSize()' function? Best regards, Lukas -- Ing.

For the Mac users: AppleScript to launch ConTeXt in a flexile way
by Thomas Floeren 22 Sep '16

22 Sep '16

Hello, Some months ago I wrote a little AppleScript script with one purpose: It should be a flexible script to launch ConTeXt typesetting, independently of the text editor I’m using and it should be capable to typeset the Product file even if I’m currently editing any component file belonging to that Product file. I used it for some time, I improved it, and I shared it with a collegue who also works with ConText on OSX. We’re still using it, many bugs have been fixed and some features were added. The script proved to be very useful for us and I thought, why not share it with the other Mac-ConTeXt people? So here it is: https://www.wuala.com/tflo/Scripts/Ctx%20Typeset/?key=75QkpizhdpFS As already said, the main purpose of the script is to launch the Ctx typesetting process (short: Ctx) on a file. Regarding the “a file” the script is very configurable and flexible: A) It can launch Ctx on a file currently opened in your text editor. It works with many text editors (BBEdit, MacVim, TextMate, etc.) as long as the editor is the frontmost process. B) It can launch Ctx on the parent Product file of the component file currently being edited. Defining a “Product file” can either be done semi-automatically or by hard-definition with two swappable register slots. C) If no eligible file is opend in an editor it will launch Ctx on the currently selected tex file in the Finder. The options added in the course of time are: A) Usage of a ConTeXt-Beta or a ConTeXt-Current installation, swappable B) Typesetting in the non-interactive shell or in the visible terminal C) Notifications D) Selection of PDF viewer (Skim, Preview, Adobe, …) E) Automatically calling the PDF viewer or not F) Optionally excluding generated PDFs from TM backup G) luatex or luajitex H) Beeps or no beeps, and so on I) Many other things, explained in the Description Also some features (“Tools”) have been added: A) Purging files including generated PDFs B) Info on the used Ctx version C) Updating the Ctx Minimal (Beta or/and Current) and archiving the old one D) Syntax Check E) Make formats, listing fonts, other, … F) Some extras added in the Extras folder (synctex with BBEdit etc.) G) Much more in the Description Some caveats: A) It works only on OS X B) The script is designed to work with 10.9 (Mavericks). It should also work with 10.8 (old notification via 3rdParty is still implemented). C) Out of the box it works only with the so called “ConTeXt Minimal Installation” (aka ConTeXt Standalone). It won’t work with TeXLive installations or any other kind of excessively screwed-up installations. But you can go into the script to make it work with anything. D) In order to get access to any text editor the script makes use of GUI scripting: you have to liberate the rights in the corresponding OS preferences. This may sound risky to you but the code is open so you can assure yourself of what the script does. E) You have to (and you really should!) read the Description that comes with the script. If you are enjoing the script please share it here, if the script is buggy, or doesn’t work for you at all please let me know too, please. Thank you best wishes -- Thomas

Hi, There is a bug with nested itemize of two different groups are mixed. For example: \defineitemgroup[legal] \starttext \startlegal[n] \item Level 1 \startlegal[n] \item Level 2 \startitemize[n] \item Level 3 \stopitemize \stoplegal \stoplegal \stoptext gives: 1. Level 1 1. Level 2 0. Level 3 The third level number is wrong. Aditya

Nested itemize horizontal/column problem
by Mikael P. Sundqvist 19 Sep '16

19 Sep '16

Hi 1) the following code \starttext \startitemize[n] \item \startitemize[a,horizontal,three] \startitem First \stopitem \startitem Second \stopitem \startitem Third \stopitem \startitem Fourth \stopitem \stopitemize \item On the outer level \stopitemize \stoptext generates the error tex error > tex error on line 9 in file /home/mickep/tmp/ctx-listexample14.tex: ! You can't use `\prevdepth' in restricted horizontal mode Isn't it possible to have nested itemize with key horizontal? 2) If I change the horizontal key to columns, then there is an extra line (the extra line in nested itemization has been discussed before, but not with these keys given, as far as I could see). I.e. the file \starttext \startitemize[n] \item \startitemize[a,columns,three] \startitem First \stopitem \startitem Second \stopitem \startitem Third \stopitem \startitem Fourth \stopitem \stopitemize \item On the outer level \stopitemize \stoptext gives the attached pdf file, where I would have exptected the first a. in the inner itemize to be on the same line as the 1. in the outer itemize. Anyone has an idea on what is going on here? Best regards, Mikael
