Creating documentation from source-files
by Willi Egger 17 Feb '11

17 Feb '11

Hi, I do still struggle with the creation of documentation derived from a source file. I tis quite difficult to nail down the hicking point. When I run context --ctx=s-mod test.tex I get the following error: pages > flushing realpage 4, userpage 2 structure > sectioning > subject @ level 3 : 0.0.0 -> Introduction .Error: PDF file is damaged - attempting to reconstruct xref table... Error: Couldn't find trailer dictionary Error: Couldn't read xref table !LuaTeX error: xpdf: reading PDF image failed I do not know where to look... The file test.run looks normal The file test.tex.prep looks normal Please refer to the test.tex file for testing. Willi

\setupalign[hz,hanging] breaks verbatim text
by C. 17 Feb '11

17 Feb '11

I have a strange problem in one of my documents. When I uncomment the line with \setupalign[hz,hanging] everything works fine. When I use it, I get this error because of a verbatim typing segment: \obeyedline ->\par \doverbatimendofline ->\dostoptagged \obeyedline \par \ifconditional \verbat... l.10 \dodisplayverbatimstop \ctxcommand ...\directlua \zerocount {commands.#1} \dodotypeblockverbatim ..., nature = "display", }} \dostoptagged \endofverbat... l.71 \stoptyping ! ==> Fatal error occurred, no output PDF file produced! mtx-context | fatal error: return code: 1 Here is the troublemaker: \starttyping test; äüöAR \test \Context \stoptyping Interestingly I was not able to produce a real minimal example, because when I remove everything except these lines, its working fine again. So there has to be at least some lines of text to break stuff. Oh yeah, and it seems that using simplefonts and Minion also plays a role. Can somebody have a look at this, please? The attached file like it is does not compile here.

HTML-like "title" attribute
by Khaled Hosny 17 Feb '11

17 Feb '11

I'm playing with some lua markdown parser[1], already added ConTeXt output support except for two minor features. HTML links and images can have a "title" attribute that shows like a tooltip, but I don't seem to find a way to do similar trick in ConTeXt, any ideas? \tooltip seems to be the closest but it requires JS which means AR only, also seems one have to click for the tooltip ti show which is not exactly the same behaviour.

What is preloaded by “mtxrun --script”?
by Philipp Gesang 17 Feb '11

17 Feb '11

Hi all, I noticed that although mtxrun preloads some of the context libs that doesn’t cover everything available during an ordinary mkiv run. What would be the canonical way to load additional libs like “luat-ini” &c. on demand? “environment.loadluafile()”? Can this be configured globally? Is it wise to mess with “own.libs” in mtxrun? Example: This snippet checks the global env for some tables. “mtxrun --script” doesn’t find any while some of them are there when processed as cld. ···8<···························································· -- http://www.ntg.nl/pipermail/ntg-context/2010/054982.html local testme = { "userdata", "thirddata", "moduledata", "documentdata", "parametersets", --"document" } for _,item in next, testme do local i = _G[item] if i then print(item, table.serialize(i)) else print(item, "Nope!") end end -- Comprehensive: --for _,k in next,table.sortedkeys(_G) do --print(k,_G[k]) --end ···8<···························································· (My issue is that I’m testing the lua internals of module code without having to startup the whole big typesetting environment. Would be much easier if everything normally accessible from inside an mkiv session was there as well.) Thanks for any insights, Philipp

using ConTeXt/LuaTeX instead of a spreadsheet program
by Paul Menzel 17 Feb '11

17 Feb '11

Dear ConTeXt folks, could you please share your experiences with or point me to a resource dealing with the following issue. I need to evaluate some physics experiments where I have some values which got measured. I thought I could use ConTeXt with LuaTeX to do all the calculations instead of the calculator and enter the results by hand or a spreadsheet program. Would I enter the values (not many) at the top of the TeX document and refer to them in the other places? Is an extra file a better approach? Thanks, Paul [1] http://wiki.contextgarden.net/Programming_in_LuaTeX

Braces in TexLive MKIV
by Tom 16 Feb '11

16 Feb '11

When I recently upgraded to TexLive MKII, I learned that \lq, etc. no longer worked in that version but that \lbrace still did. Today, I tried MKIV and find that \lbrace does not work in MKIV. So, I tried \braceleft because \quoteleft worked in TexLive 2010 MKII. Neither \lbrace nor \braceleft work in MKIV. What is now the proper representation for this character?

Table of Contents issues
by Tom 16 Feb '11

16 Feb '11

Using a very recent download of TexLive 2010 (MKII) on my PC, my success generating a useful table of contents has been somewhat limited. I can't figure out how to put the title, "Contents," in the font I desire. The various parameters I found in the documentation affect the chapter titles and the page numbers but nothing I've found allows me to control the title of the ToC. What am I overlooking? I would also like for the unnumbered "chapter" titles, such as introduction or preface, to align with the other chapter titles, not with their numbers. Aligntitle seems to have no effect on anything from what I have seen. \definehead [intro][chapter] \setuphead [intro][number=no,textstyle=\ss\bf] \setuphead [chapter][textstyle=\ss\bf,numberstyle=\ss\bf] \definecombinedlist [content][intro,chapter,section] \setupcombinedlist[content][style=\ss\bf,textstyle=\ss\bf,pagestyle=\ss\bf,n umberstyle=\ss\bf,aligntitle=yes] \setuplist [intro][headnumber=no] \starttext \completecontent \intro{Introduction} \input knuth \chapter{First chapter} \input knuth \chapter{Second Chapter} \input Knuth \stoptext Tom Benjey 717-258-9733 voice 717-243-0074 fax blog: www.TomBenjey.com

conditional evaluation and section names
by Daniel Lyons 16 Feb '11

16 Feb '11

Hi again, I have this in my environment \startsetups[sectioninfo] \ss \rlap{\userpagenumber} \hfill § \getmarking[sectionnumber][current] \emspace \bf \getmarking[section][current] \hfill \llap{} \stopsetups \setupheadertexts[\setups{chapterinfo}][] [] [\setups{sectioninfo}] This seems to be working, but there are a couple improvements I'd like to make and I'm not quite sure where to start: 1. If I'm in a later chapter than the current section is defined in, it shows up anyway. I'd like to prevent that. 2. If I'm in a chapter that doesn't have sections, I'd like the chapter name to show up instead (without the §). I'm not sure at all how to go about doing this. I suspect the answer is to use plain TeX but I don't understand TeX's conditional system well enough to figure out how to make it work (nor ConTeXt's marking system). If anyone can help, I'd greatly appreciate it! Thanks again, — Daniel Lyons
