It took me a while to make your code operational in the way I need it. For the new example you gave is still an "integral file". My project, like most book-projects, I guess, is modular with a master file Project.tex, into which everything else, setups, .bbl's, front- and backmatter, the various chapters are input. Though strictly speaking it would not be impossible to add some 1000 lines of index entries before \startproject, it would not be especially handy, and I cannot believe that it would be the proper ConTeXt-way to do it. I found that when I split your code, transferred the top part to a new file, which I named "IndexItems", and input that into the other half, the text proper, it works. But when I add another file with indexentries, for instance "indexitemsnames", then only one of them, the one at the top is used. So it seems that the whole collection of index items must be in one file. Is that the only possibility or are there ways to enable the use of several collections of index items? Best regards, Robert

A macro which gives a random name
by Otared Kavian 19 Apr '15

19 Apr '15

Hi everyone, In the example below I define a macro which chooses at random a name from a list of names. But I wonder whether this can be done in a more clever way without using a numerical macro created with math.random in Lua. The shortcoming of the macro below is that before hand I must know the nomber of elements in the list of names (for instance 5 in the example below), while it may happen that I need to create as many as random names that there are elements in the list, but sometimes I don’t know what is this number. Thanks for any insight and help. Best regards: OK %%%% begin random-names.tex \setuprandomize[2015] % set a seed \starttext \startluacode Name = {'F', 'G', 'u', 'v', 'W'} \stopluacode \define[3]\RandomName{% \setevalue{Named#1}{\ctxlua{tex.print(math.random(#2,#3))}}} \define\RandomFunctionName{\ctxlua{tex.print(Name[\NamedFunctionNumber])}} \dorecurse{10}{\RandomName{FunctionNumber}{1}{5}% Give an example of a function $\RandomFunctionName : {\Bbb R} \longrightarrow {\Bbb R}$ which has a derivative only at the origin, and such that $\RandomFunctionName(0) = 1$.\par \hairline\par} \stoptext %%%% begin random-names.tex

This code works beautifully in this way, with only a few index entries at the top of the file, before \starttext. But how can I deal with the thousand or more index items in my project, which I have collected in four separate dedicated files with indexentries, like the three shown in the example-code. I have really no idea what else should be in these files, what sort of name they should have, in particular extension, and how and where I can input them. I use TeXShop as my texteditor but that is probably not relevant here. Can you give me some guidance, please? Thanks in advance. Best regards, Robert Blackstone

Caption location with vertical \startplacefigure

How can I get the caption for the vertical figures (figures 2 and 4 in the example) aligned below the figures with the caption width limited to the figure width?

Hidden chapter header? ... was: Change counter of chapters
by Jaroslav Hajtmar 18 Apr '15

18 Apr '15

Hello ConTeXist My last Subject contribution maybe so misleading that it nobody react. I'll try therefore to bring different view: Exist any possibility of creating some kind of hidden chapters (sections, subsections)? The command would increase the counter of chapters (sections, subsections). Maybe it seems as rape of ConTeXt, but in certain moments this option would help me. In my case it is the integration of practical part of project (worked in ConTeXt) into Word project:-(... For example I need to start writing any text from 53 page and such from the 5th chapter (or section). It is possible in a similar way as I set the start page number set also the counter of chapters (sections)? Thanx for help. Jaroslav Hajtmar Here is my minimal example: \starttext %\hiddenchapter{Fictive chapter} %\hiddenchapter{Fictive chapter} %\hiddenchapter{Fictive chapter} %\hiddenchapter{Fictive chapter} \page \setcounter[userpage][53] \chapter{Fifth (actually first) nonfictive chapter} blablabla \stoptext

imposition not working in latest beta

Hans, I’m afraid that imposition is not working with latest beta. Either the command (it crashes): context --extra=arrange --printformat=2UP --paperformat=A4*A3,landscape a.pdf Or the following sample has no text in output: \setuppapersize [A5][A4,landscape] \setuparranging [2UP] \setuplayout [backspace=0pt, topspace=0pt, width=middle, height=middle, location=middle, header=0pt, footer=0pt] \starttext \input knuth \stoptext Many thanks for your help, Pablo -- http://www.ousia.tk

Howto typeset physical half-life
by Christian Prim 18 Apr '15

18 Apr '15

Hi a year or so before one could simply typeset the physical half-life as shown in MWE: \usetypescript[palatino] \setupbodyfont[palatino] \starttext ½ α \m{T_α} \m{T_½} \stoptext The greek letter is just to show, that utf-8 works as expected. In actual beta (and probably longer before) this doesn't work anymore. What have I missed? Thanks Christian

How to exclude certain figures from list of figures in ConTeXt?
by Geert Verhaag 17 Apr '15

17 Apr '15

Hi, I was wondering whether it is possible to exclude certain figures of a document using the \placelistoffigures command in ConTeXt? For example those that start having a reference like ['fig:figure:exclude']? Gerard

how to set figure label ?

Hi, how can I set a "label" for a figure without \placefigure[][fig:...]{} for some "figures" I use strange macros -- and at those places I get errors when calling \placefigure BUT I'd like to check the page numbers of those places using \doifreferencefoundelse{fig:bild\the\bildnr}% and right now I get references > unknown reference '[][fig:bild5]' for those pictures... thanks -- and greetings from the DANTE meeting in Stralsund, Germany Harald PS: Hans -- we miss you so much!!! -- "I hope to die ___ _____ before I *have* to use Microsoft Word.", 0--,| /OOOOOOO\ Donald E.
