Grabbing first letter of a sentence
by Mathieu Boespflug 15 Nov '10

15 Nov '10

Hi, I'd like to get access to the first letter of a chapter for the purpose of laying out the chapter heading, but I'm having difficulty with expansion. Here's my attempt: \def\MyChapterTitle#1#2{% \def\doMyChapterTitle##1##2^{% {\tfb ##1}##2 } #1 \doMyChapterTitle#2^ } setuphead[chapter][command=\MyChapterTitle] \starttext \chapter{Foo} bar \stoptext This doesn't work because the chapter title isn't expanded out before passing it to \MyChapterTitle. I know there is deeptextcommand but I need the chapter title during the layout of chapter number + title, so I need to use command instead of deeptextcommand. I attempted to get hold of the chapter title using the following \def\MyChapterTitle#1#2{% \def\doMyChapterTitle##1##2^{% {\tfb ##1}##2 } #1 \expandafter\doMyChapterTitle\expandafter{\fetchmark[chapter][first]}^ } but that doesn't seem to work either. Any ideas? Many thanks, M

Section horizontal space adjustment (LaTeX -> ConTeXt) (reduced attachs)
by Procházka Lukáš Ing. - Pontex s. r. o. 15 Nov '10

15 Nov '10

Hello all, what is the simplest way how to change the horizontal space between the number and the name of a section (chapter, subsection...)? (Migrating from LaTeX to ConTeXt.) There are two test documents attached - - t-Sec2.pdf - to see the default view of LaTeX section number/text spacing, - t-Sec.pdf - to see the same by ConTeXt (i.e. some less h-space). What is the best (or simplest) way how to adjust this? I tried to work with stopper and/or separator in \setupheads, but - to be honest - I don't know when they go to an action. I achieved the required job by defining a new command \MyCmd - but is this the best way? Or are there better options or commands to achieve this? - See the code (and result): --- \def\MyCmd#1#2{#1\hskip3ex#2} \setupheads[stopper=STOPPER,separator=SEPARATOR,command=\MyCmd] % When are the "stopper" and "separator" applied? \starttext \chapter{AAA} \section{BBB} uuu \stoptext --- Cheers, Lukas -- Ing.

Hook environment into head/structure setup
by Andreas Harder 15 Nov '10

15 Nov '10

Hi all, I don't think it is yet possible, but it would be nice if there was something like: \setuphead % or perhaps \setupstructure [chapter] [beforestructure=\startlinenumbering, afterstructure=\stoplinenumbering] Which should result in: \startlinenumbering \startchapter[title=test] Text \stopchapter \stoplinenumbering Is there already a way to achieve this? I've consequently used \start-\stopchapter, maybe one can append \start-\stoplinenumbering to them? I would appreciate any help Andreas

I could confirm that there is the problem with context minimal installation on linux-64. The cause of the problem is missing permission for executable. Currently I could build the formats only if I split the actions: update and make. P.S. To ensure that the same problem would not arise in future the 'update' and 'make' procedures should be splitted and between them 'chmod +x bin/texlua tex/texmf-linux-64/bin/luatex' (texmf-$platform) is inserted. --- WBR, Vladimir. -- Perfect day for scrubbing the floor and other exciting things.

column breaks and TABLE
by Philipp Gesang 15 Nov '10

15 Nov '10

Hi all, with natural tables I can’t seem to get column breaks right. Example: ··8<····························································· \setuppapersize[A5][A5] \definecolumnset[three][n=3] \starttext \startcolumnset[three] \dorecurse{5}{ \subject{Test nr. \recurselevel} Some paragraph.\par \penalty10000 % comment me to get even footer; well, sort of … \bTABLE[split=yes] \bTABLEbody \dorecurse{80}{ \bTR\bTC Nr.\eTC\bTC\recurselevel\eTC\eTR } \eTABLEbody \eTABLE Text after.\par\column } \stopcolumnset \stoptext ··8<····························································· The crude prevention of a column break before the table appears to cause the first column to extend into the footer. However, without the ‘\penalty’ the table will always appear on a new column -- not looking well if there’s not much to typeset besides the table itself. Is there a way to get the best of both worlds: an even footer without a break before the table? I’d be grateful for any hints or suggestions, Philipp -- () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments

XSL-FO to PDF?
by Peter Davis 15 Nov '10

15 Nov '10

Is there some recent information on using XML, and specifically XSL-FO, with ConTeXt? The pages on the contextgarden wiki appear to be 5 years old or more, and even the archive of this list seem pretty sparse on recent information. I'm trying to find the most direct route from XSL-FO to PS or PDF. I'll be generating hundreds or thousands of XSL-FO documents, and would like to process them. Thank you. -pd

beta
by Hans Hagen 14 Nov '10

14 Nov '10

Hi, I uploaded a new beta (so the minimals will have it in about an hour): - some cleanup at the lua end as side effect of documenting lua interfacing as part of writing the cld manual - a couple of bug fixed in the lua code that crept in during some optimizations - removal of some old lua code (not needed any more or replaced by better code) - a couple of patches (or extensions) to macros (due to reports on the list); for instance, the HideLayer and VideLayer reference actions were never implemented; also, some animation code has been added (for WS) - definitions like \definedfont[file:lbr.pfb] are ok now (remapped onto afm, a few line harmless extension) - a replacement of the existing marking mechanism (as used for running headers and footers): less interference with typesetting as mark nodes are no longer part of the game; more robust synchronization of chained marks (sectioning); more robust handling of marking in columns and columnsets; experimental marking in arbitrary constructs (thomas might like that one); not all is tested but we have: the usual marking: first, last, previous, current; these are strict in the sense that they take sectioning into account some new, less strict marking: firstpage, lastpage, previouspage; these ignore sectioning related resets some experimental methods: next, nextpage; these concern parts of paragraphs that end up on the next page, so limited lookahead (in there is interest we can make that full lookahead i.e. future marks) the usual column related marking: \getmarking[chapter][first]/ \getmarking[chapter][page][first]/ \getmarking[chapter][column:first][first]/ \getmarking[chapter][column:1][first]/ \getmarking[chapter][1][first] even more expermental: \definemarking[boxmark] \setbox0\ruledvbox{ \marking[boxmark]{tufte} \input tufte \par \marking[boxmark]{ward} \input ward \par } \synchronizemarking[zerobox][0] \box0 \getmarking[boxmark][zerobox][first] \getmarking[boxmark][zerobox][last] anyhow, it might be that something is broken, but at least this implementation has more potential - the properties mechanism is obsolete and replaced by three mechanism that used them (originally properties dealt with specific engine/backend functionality); the most important ones are \defineviewerlayer[name][options] \startviewerlayer[name]....\stopviewerlayer \viewerlayer[name]{...} and \defineeffect[name][options] \starteffect[name]....\stopviewerlayer \effect[name]{...} where we have predefined (as with former properties): \defineeffect [inner] [alternative=inner,rulethickness=.25pt] \defineeffect [outer] [alternative=outer,rulethickness=.25pt] \defineeffect [both] [alternative=both, rulethickness=.25pt] \defineeffect [normal] [alternative=normal] \defineeffect [hidden] [alternative=hidden] \defineeffect [stretch] [alternative=stretch,stretch=1] the properties commands are still there but map onto these so older code should work ok (but somewhat less efficient) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

why nil argument
by Hans van der Meer 14 Nov '10

In transforming dates through a Lua-call I get a nil error I do not understand. The luatex code = \startluacode hvdm = hvdm or {} require "lpeg" -- Transform date in Lua from yyyymmdd to dd-mm-yyyy with checks hvdm.day = lpeg.R("02") * lpeg.R("09") + lpeg.P("30") + lpeg.P("31") - lpeg.P("00") hvdm.month = lpeg.P("0") * lpeg.R("19") + lpeg.P("10") + lpeg.P("11") + lpeg.P("12") hvdm.year = lpeg.R("12") * lpeg.R("09") * lpeg.R("09") * lpeg.R("09") hvdm.date = lpeg.C(hvdm.year) * lpeg.C(hvdm.month) * lpeg.C(hvdm.day) * -1 / "%3-%2-%1" \stopluacode \def\FormatDate#1{\ctxlua{tex.print(tostring(hvdm.date:match(#1)))}} Calling \FormatDate(1) is OK although it returns "nil" (correct would be #1 = 20101114 Calling \FormatDate(A) is not OK with the error: ! LuaTeX error <main ctx instance>:1: bad argument #1 to 'match' (string expected, got nil) stack traceback: [C]: in function 'match' <main ctx instance>:1: in main chunk. It is no problem if the function returns the string "nil" from tostring() but an error like this I would like to avoid. Hans van der Meer
