bookmarks using linebreaks in chapter titles
by Sanjoy Mahajan 03 Nov '06

03 Nov '06

I was trying out line breaks for long titles (at least, long when set in 36 or 48pt text), as well as have pdf bookmarks, so I defined a \1 shorthand local to the chapter heading: ====================================================================== \setupinteraction[state=start] \placebookmarks[chapter] \setupinteractionscreen[option=bookmark] \setuphead[chapter][before={\bgroup\def\1{\hfil\break}}, after={\egroup}] \starttext \chapter{Long\1 title} hello \stoptext ====================================================================== If I inline the \1, as in \chapter{Long\hfil\break title}, then it's mostly fine except that the bookmark has "hfil penalty ..." Is there's another way to avoid that problem? Perhaps a magic option that says what the bookmark should be, the way one can tell \index what to typeset in the index when it is different from the inline text. One solution is to forbid hyphens during the \chapter (with before= and after= definitions) and also shrink the \hsize enough so that tex line breaks where I want, but that method requires unintuitive, fontsize-dependent dimension guessing for each chapter. Putting in line breaks by hand is not too bad. Plus one might want to break the lines according to meaning, which does not always produce the same results as where breaks would go according to line length. But meanwhile trying the hack method above, I get this error (./q.tuo) (./q.tuo) ! Undefined control sequence. <argument> Long\1 title \sanitizePDFdocencoding ...docencoding \edef #2{#1 } \doPDFinsertbookmark ...oding #3\to \bookmarktext \stripstring \bookmarktext.. \doplacebookmarks ...okmarkelement \flushbookmark \egroup \else \expanded {\.. <to be read again> \setupinteractionscreen l.3 \setupinteractionscreen [option=bookmark] It's from this line in q.tuo \listentry{chapter}{1}{1}{Long\1 title}{2--0-1-0-0-0-0-0--1}{1} and the \1 is not defined during \listentry, only during the \chapter. I didn't have a problem when the same code was part of a product (each component being chapter in a book, with the \setuphead in an environment file) -- only had it when I compiled one component, which is how I got to the test case above.

Splitting a float that isn't a table
by Duncan Hothersall 03 Nov '06

03 Nov '06

I define a floating block called Exhibit \definefloat[Exhibit][table] which just contains paragraphs of text. I'd like to be able to split it using the \splitfloat mechanism but that only seems to work if the content of the float is a table, not paragraphs. ---- \definefloat[Exhibit][table] \starttext \input tufte\par \splitfloat[lines=auto]{\placeExhibit{Knuth}} {\dorecurse{4}{\input knuth \par}} \input tufte\page[yes] \stoptext ---- This outputs "there is nothing to split" in the resultant PDF. Is there any way to achieve the equivalent of ---- \definefloat[Exhibit][table] \starttext \input tufte\par \splitfloat[lines=auto]{\placeExhibit{Knuth}} {\bTABLE[frame=off]\dorecurse{4}{\bTR\bTD\input knuth \eTD\eTR} \eTABLE} \input tufte\page[yes] \stoptext ---- without having to make every paragraph a table cell? Thanks in advance. Duncan

overlay page background missing
by Paul Jones 03 Nov '06

03 Nov '06

Hello all, I am trying to put together a wedding book. I would like a nice watermark behind the text on each page. Left page containing the word 'together', and right page containing the word 'forever'. I can get this done with an overlay, but it is always centered in the page. So after reading some threads about layers in overlays I thought this might work. Putting a layer into an overlay does give me the ability to positiong the words, but I can no longer get them to show up on all of the pages. Am I doing this in a resonable way? Why did the setupbackgrounds stop working when I put the layer into the overlay? Much thanks, Paul %output=pdf \setuppagenumbering[alternative=doublesided] \setupcolors[state=start] \setupbackgrounds[page][background={WatermarkOverlay}] \startsetups WatermarkSetup \doifoddpageelse {\framed[frame=off,foregroundcolor=gray] {\scale[sx=12,sy=12] {\rotate[rotation=20.0]{forever}}}} {\framed[frame=off,foregroundcolor=gray] {\scale[sx=12,sy=12] {\rotate[rotation=20.0]{together}}}} \stopsetups \definelayer[WatermarkLayer] \setlayer[WatermarkLayer][hoffset=-4cm,voffset=12cm]{\setups{WatermarkSetup}} \defineoverlay[WatermarkOverlay][{\placelayer[WatermarkLayer]}] \starttext \framed[height=\textheight, width=\textwidth, background={WatermarkOverlay}, frame=on]{overlay frame} \chapter{first} \dorecurse{10}{\input tufte } \chapter{second} \dorecurse{10}{\input davis } \chapter{third} \dorecurse{10}{\input zapf } \stoptext

feedback on the wiki Linux_User_Installation article
by Antoine Junod 03 Nov '06

03 Nov '06

Hello list, I'm trying to make a fresh minimal install following the wiki article 'Linux User Installation'. All goes fine till the 'texexec --make --alone' command. It says me 'the file 'texexec.rb' is not found'. I can copy it in the texmf-linux/bin directory but it trigs other errors. I can correct that error by recursively copying all the files of the texmf-local/scripts/context/ruby/ directory into the texmf-linux/bin/ one. Should I update the wiki with that information or is it a problem tied to my system, or maybe a problem of the minimal context distribution/binaries files? Thanks for your replies. -AJ

new beta / mp
by Hans Hagen 03 Nov '06

03 Nov '06

Hi, I uploaded a new beta release. This one has support for some fresh metapost features (mpprocsets). This means that mp inclusion is slightly faster in mkii (some 5-10%) and that the (not yet public) mkiv converter is now faster than the mkii one (some 10%) due to the cleaner mp output code. Around 20/11 we need to go current because of the tex live code freeze which means that serious bugs need to be fixed before that time.

formula, bookmarks and misc
by Sebastian Rooks 03 Nov '06

03 Nov '06

Dear ConTeXters, 1/ I would like to use a named formula with a reference containing several subformulae each with a reference. The closer I can get to is to add an empty namedformula followed by subformulae (see test file below). How can I get rid of the empty line with a number in the pdf ? 2/ I'm using bookmarks but abbreviations in heads do not work properly. I've used a workaround some 3 years ago but I cannot remember which. Any suggestion ? (see test file below) 3/ What should I do to get the bookmarks numbered with their chapter/section/ etc. number ? (see test file below) 4/ How can I redefine the \vec command in my formulae without having a warning "system : command \vec is already defined" 5/ I do like a lot the minimum distribution so easy to install. It would be even better if bibtex can be added. It's only 82.8 KiB Thanks for ConTeXt (special thanks to Hans and Taco of course), it's really a pleasure to work with it.

incorrect spacing in mathcases
by M.J. Kallen 02 Nov '06

02 Nov '06

Hi, the following example shows space missing after the inequality sign: \startformula i = \startmathcases \NC i, \NC \text{if} i = j, \NR \NC j, \NC \text{if} i \neq j. \NR \stopmathcases \stopformula An extra '\ ' after \neq solves this, but I think this shouldn't be necessary since $i \neq j$ does not require this fix.

Forcing XeTeX output
by Philipp Reichmuth 02 Nov '06

02 Nov '06

Hi, is there a first-line comment directive or a \setupoutput[] parameter to force usage of XeTeX just like the --xtx commandline switch? Consider the following document: ---------------------- % ??? = xetex??? \starttext This is a piece of text \stoptext ---------------------- I just experimentally tried "engine=xetex", "tex=xetex" and "output=xetex" on the first line. The first two actually launch XeTeX, but they bail out with the comment "you should use pdfetex instad" and a \wait command, and the last one runs pdfetex instead and produces a DVI file. Philipp

XeTeX and built-in glyph generation
by Philipp Reichmuth 02 Nov '06

02 Nov '06

Hi, I have a question regarding ConTeXt, XeTeX and the use of Unicode fonts with diacritic characters which I use quite a lot. (Note also that I'm a novice user.) Consider the following extreme example (using Gentium <http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&id=gentium>): ------------------- \definetypeface[lucida][rm][Xserif][Lucida Bright] \definetypeface[gentium][rm][Xserif][Gentium] \setupbodyfont[gentium] \starttext Ṯḥíş ıš ā pìėçẹ ȯf ṭēxt. \stoptext ------------------- If you typeset this with 'texexec --xtx', you get very different results with Gentium vis-a-vis Lucida because of the different glyph repertoires of both fonts. This is a bit unsatisfactory because ConTeXt has all the logic already in place to construct most of these these from base characters plus accents where needed. Of course I can go through my Unicode text manually and change all the missing characters to something like \={e}, but that is not a good solution either; having to sift through your entire document because your publisher demands a different font makes you feel more than a bit stupid :) Is there a way to tell ConTeXt what Unicode characters are available in a font and which ones it has to build using TeX's accent functions? I guess in the above example it would be difficult because no regime gets loaded at all. What would be ideal in my case would be a configurable UTF-8 regime where I could specify the following on a per-typeface basis: - character[ range]s which get passed directly to the underlying engine (useful mainly with XeTeX and possibly with Aleph/Omega) - character[ range]s which get constructed from accents - character[ range]s which get used from a different typescript; for example if I have passages or quotations in a script which isn't available in my typescript, it would be nice to say that "all IPA/Greek/Old Church Slavonic" should come from a substitution typescript where these scripts are available and look good. Is such a thing possible? Philipp
