Module s-pre-19 doesn't work anymore

Hi People, I'm quite font of s-pre-19 and derivatives, however this fails on my current system. Sample file: ================================================== \usemodule [pre-19] \starttext \Topic{Test} test. \stoptext ================================================== Error message: ! Missing number, treated as zero. <to be read again> \endcsname \@@amvbox ... -\pagebackgroundvoffset +\endcsname \c!topoffset \relax \box \... <argument> ...ght\c!left }\interactionmenu [right] \getvalue {\??am right\c!r... \firstofoneargument #1->#1 \next2 #1,->\docommand {#1} \doprocesscommaitem \doprocesscommalist ...item \gobbleoneargument #1, ]\relax \global \advance \... ... l.12 \stoptext Hopefully someone has a pointer? It works if I disable the menu, i.e. if in \setupinteraction I have menu=off, it's fine. I'm on Ubuntu 8.10. Some more TeXExec | runtime: 303.108203 $ texexec --version TeXExec | version 6.2.0 - 1997-2006 - PRAGMA ADE/POD $ tex --version TeX 3.141592 (Web2C 7.5.6) kpathsea version 3.5.6 -- Cheers, Berend de Boer

page break before box
by Jörg Hagmann 06 Nov '09

06 Nov '09

Sometimes I get page breaks before a box as follows (didn't manage to write a minimal example): Some text on the page (even one line only) <page break, leaving most of the page empty> A small box (much smaller than the empty space on the preceding page) \page[no] and \dontleavehmode don't do anything. Example for a box: \definestartstop[Point][before={\setupbackground[background=color,backgroundcolor=lightgray, frame=on,framecolor=red,topoffset=0.25cm,bottomoffset=0.25cm,leftoffset=0.5cm,rightoffset=0.5cm, before={\blank[big]}]\startbackground},after=\stopbackground] Something simple, surely?

where to place \index
by Oliver Buerschaper 06 Nov '09

06 Nov '09

Hi there, Reading the wiki I saw that \index{keyword}keyword should be used rather than keyword\index{keyword}. How should I proceed for names? For example \defineregister[person][people] Albert \person{Einstein, Albert}Einstein vs. \index{Einstein, Albert}Albert Einstein What happens in either case? Oliver

Tracking macro expansion
by Oliver Buerschaper 06 Nov '09

06 Nov '09

Dear all, how can I check whether a macro I defined is actually expanded into what I intended? For example, if I define \define[2]\Test{#2, {\it #1}} is there a (Lua?) function like check(\Test{Hello}{world}, string) that would return true for string = "world, {\it Hello}" and false otherwise? If the macro is a bit more complicated than this I usually get caught by a mistake rather quickly ... so a quick check would be very handy for me. Many thanks for your help, Oliver

Usage of filename in document
by Martin Scholz 06 Nov '09

06 Nov '09

Hi List, is there a way in conTeXt how I can use a filename, so that I can write a text where I can refer to it for using it in the following scenario: I need 4 documents with nearly the same content. what I like to do is to switch in the document depending on the called filename. as I got a file called invoice.tex and create some links to this file called delivery.tex order.tex and so on and now call texexec invoice.tex or texexec order.tex I want the document to recognize in the first case that it is invoice and in the second case that it is order, so that I can use an if then else environment on the different parts where I can define the following if{filename==invoice} then{print this content} else{} if{filename==order} then{print this part of content} else{} Thanks for your help. Greetings Martin

Allow indentation of typing environments
by Matthijs Kooijman 05 Nov '09

05 Nov '09

Hi all, I'm having the following problem (or rather, inconvenience). When typing my ConTeX, I tend to properly indent all of my text, following the section headings. This makes my source a bit more readable. However, when I apply the same tactic to typing environments, all of the indentation is preserved in the output. This is of course to be expected, but it requires me to break the indentation for every typing environment, making very ugly source. Anyone else who also finds this problematic? What I'd like to see, is an option for a typing environment (say, stripindent) that makes the pretty printing code remove a fixed amount of indentation from every line. I've implemented this for some of my custom prettyprinters, but that's a lot of duplicate code, and it won't help others. Ideally, this would look at the indent of the \starttyping command and strip that much, but I don't think this is possible in TeX (or is it?) Slightly less ideal would be to look at all the lines, decide what the smallest indent is, and strip that. This would of course require buffering all the lines and start processing only when the final one is in, which is not very efficient given the current pretty printer implementation. What will probably work well enough is to look at the first line, and strip that much whitespace from all lines. This could be implemented entirely in lua. Would there be any interest for something like this? I could whip up a patch if there is. Where would be the logical place to do this? I don't see any need to let individiual pretty printers keep control over this, so I guess it is best handled before the pretty printers get at the line (So in buffers.typeline, probably. I guess inline \type commands don't need this, so this should work out). This also needs some initialization in buffers.type and buffers.typefile so we can detect what the first line is. Ideally, there would also be some sort of manual override, like: \starttyping[stripindent=4] but, I don't think any options are supported there currently (and adding them is very much over my head, since that would involve serious TeX coding...). To reach a conclusion, if I managed to implement this properly, would there be any interest for using this and including this in ConTeXt? Gr. Matthijs

Getting the width of an expression inside lua
by Matthijs Kooijman 05 Nov '09

05 Nov '09

Hi all, I'm wondering if there is any way to get the width of some TeX (or rather, ConTeXt) expression inside lua, to do some math with it and output it again. I've found the tex macro \setwidthof, which served me well at first, but I need to do some more complex things with this widths (like taking the maximum value of a bunch of widths and using that again in some other places). Doing this in TeX would be my fallback option, but that would be a lot more complex (I'd be generating the TeX code for it, but still...). So, I'm looking for a function that accepts a string (and possible catcodes) and returns the dimensions of that string as if it would be rendered directly with tex.sprint & friends. I've looked around the LuaTex manual a bit, and found the node.dimensions function. However, that function requires a node object, which I have no clue how to get at. Perhaps I could use \setwidthof and get at the value it assigned? Any suggestions? Gr. Matthijs
