trying to fix page ranges in bibliography
by Florian Wobbe 29 Jan '11

29 Jan '11

Hi, I'm trying to insert the macro \pagerange into the code from texmf-context/tex/context/base/bibl-tra.mkiv but I'm quite lost. The macro should make proper page ranges from the bibtex file entries (Pages = {...}). That means remove any whitespace before and after the hyphen and double a single hyphen: 7-9 -> 7--9 1 - 3a -> 1--3a \def\pagerange#1% {\directlua{ range = string.gsub("#1", "\%s*[-\%s]+", "--") tex.sprint(range)}} Thanks for suggestions, Florian

large right brace grouping lines of equations
by Jeong Dalyoung 29 Jan '11

29 Jan '11

Dear all, First, thanks Wolfgang and Hans for suggestions about the chapter head. Using \cases, I can use large left brace for lines of equations. But, how to put a large right brace after lines of equations which groups them. Is it possible in the \startformula\startalign ... \stopalign\stopformula? Thanks Best regards, Dalyoung

Head: why different distances?
by Procházka Lukáš Ing. - Pontex s. r. o. 29 Jan '11

29 Jan '11

Hello, I created a simple file which derives head style 'subsectionX' from 'subsection'. The only difference is the the latter has 'align=middle'. --- \setuphead[subsection,subsubject][style=\bfa] \setuphead[chapter,title, section,subject, subsection,subsubject, subsubsection,subsubsubject] [distance=1.5em] \definehead[subsectionX][subsection] \setuphead [subsectionX] [align=middle] \starttext \subsection{Model} \subsectionX{Model} \stoptext --- The problem is that the space between the subsection number and the text differs (and it doesn't depend on whether 'distance' was set to '1.5em' or not). You can also see the picture with measured values. Why this effect? And how to make both distances equal? Kind regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

\bufferprefix in MKIV
by Mojca Miklavec 28 Jan '11

28 Jan '11

Dear Hans, one of the latest versions of MKIV breaks the following code: \edef\GNUPLOTfile {\bufferprefix gnuplot-\GNUPLOTnumber}% since \bufferprefix is not defined any more. Is there any reason for that? In particular ... meta-ini.mkiv: {\bufferprefix mprun.#1} page-app.mkiv: {\immediate\openout\scratchwrite=\bufferprefix\@@texdim.tmp page-app.mkiv: {\readlocfile{\bufferprefix\@@texdim.tmp}\donothing\donothing} page-app.mkiv: \executesystemcommand{texexec \bufferprefix\@@texapp.tex --once --batch}% page-app.mkiv: \executesystemcommand{dvips \bufferprefix\@@texapp}% page-app.mkiv: \executesystemcommand{ps2pdf \bufferprefix\@@texapp.ps \bufferprefix\@@texapp.pdf}% page-app.mkiv:% \executesystemcommand{texmfstart pstopdf \bufferprefix\@@texapp.ps \bufferprefix\@@texapp.pdf}% page-app.mkiv: [\bufferprefix\@@texapp.\ifdone eps\else pdf\fi] Thanks, Mojca

tooltip in a buffer (beta)
by Peter Rolf 28 Jan '11

28 Jan '11

Hi Hans, I have overseen an unwanted horizontal skip in my menu test graphic. Mh, donno what this is... it's no skip nor a simple spurious space (as I use \removeunwantedspaces in front of that macro). A minimal example is attached. No urgent case... Best wishes, Peter

first-setup for windows
by Mojca Miklavec 28 Jan '11

28 Jan '11

I would like to ask windows users to test the attached setup file if it works any better (and to make sure that I didn't do any mistakes while typing). I have put the updated version of first-setup.sh on the server already, but for Windows I simply don't dare to do it until somebody confirms that it seems to be ok. In both cases it would be great to get feedback if the problems with missing files are solved. Mojca PS: please remove the .txt ending (gmail doesn't allow sending .bat files)

Comment on new "Page Design" Chapter for new manual.
by John Culleton 28 Jan '11

28 Jan '11

The question of page dimensions can be very confusing for the raw beginner. I suggest the something like the following as a lead in: ----------------------------------------------------------- For a printed page we really have to deal with three different sets of dimensions. The body of the text exclusive of headers, footers etc. is called the type block. In TeX the measurements of the type block are called \hsize and \vsize. When text is being laid out each paragraph is generally no wider than the \hsize and when \vsize is exceeded the page is ended and a new one is started. The actual page size of the finished document is measured with \pdfpagewidth and \pdfpageheight. For most documents this is the last set of dimensions needed. In a few cases "camera ready copy" is required which means that the final printed page image is centered on a larger piece of paper stock, often with trim marks indicating the boundaries of the page size. For example here are the dimensions for a book recently printed: hsize =4.25 in vsize =7 in pdfpagewidth = 6 in pdfpageheight = 9 in stockwidth = 8.5 in stockheight = 11 in. ----------------------------------------------------------------------------------- The terminology may need some refinement but you get the idea. Think of the "Man from Mars" encountering Context and even TeX for the first time. -- John Culleton Create Book Covers with Scribus: http://www.booklocker.com/p/books/4055.html Typesetting and indexing http://wexfordpress.com book sales http://wexfordpress.net Free barcode: http://www.tux.org/~milgram/bookland/

Hello, how to test by Lua whether a Ctx buffer exists? --- \startbuffer[A] Aaa aaa \stopbuffer \starttext \getbuffer[A] Test %\getbuffer[NonExisting] Vvv \stoptext --- To get something like 'context.buffers.A' -> no-nil and 'context.buffers.NonExisting' -> nil?
