Overwriting buffer causes LuaTeX error
by Marco Patzer 19 Sep '13

19 Sep '13

Hi, the following example causes 1) strange message: “invalid \starttext ... \stoptext structure” and 2) !LuaTeX error: PDF inclusion: file has changed 'Hga-typeset-buffer-001.pdf' ==> Fatal error occurred, no output PDF file produced! \starttext \startbuffer [foo] foo \stopbuffer \typesetbuffer [foo] \startbuffer [foo] foo \stopbuffer \typesetbuffer [foo] \stoptext Marco

bug? gap appears in columnset
by Lars Huttar 19 Sep '13

19 Sep '13

Hello, We have a document where a gap occurs in a columnset under certain conditions. It seems to be a confluence of: - 2 sections, each with 2-column columnsets - \page[empty] between them - the 2nd section has a tighter interline space The problem is that on the first page of the second section, a two-line gap appears where gridlines 50 and 51 are. It may be a coincidence, but 50 is also the number of lines per page in the first section. We've found that "coincidence" to be true even with different page and font sizes. Can anyone tell us a way to get rid of the gap? We've tried things like \setupcolumnsetlines[columnsetbibliography][1][1][-1] \setupcolumnsetlines[columnsetbibliography][1][2][-1] with various values for the last parameter, but nothing helps. Below is a small, self-contained sample. Thanks for any help you can give.

Inline math in table in combination fails
by Marco Patzer 19 Sep '13

19 Sep '13

Hi, The following example results in the error “You can't assign a glue_spec node to a prev field” \starttext \startcombination [2*1] {\starttable [|c|] \NC \math{1} \VL\NR\HL \stoptable}{} {\starttable [|c|] \NC \math{2} \VL\NR \stoptable}{} \stopcombination \stoptext It works without the combination, without the vertical or horizontal rule and when no math mode is used. It used to work some time ago, so I assume it's a bug. Marco

Clean Machine, MacTeX 2013 installed, ConTeXt problem
by Gerben Wierda 19 Sep '13

19 Sep '13

As my computer died I had to set up a clean one. I installed MacTeX 2013 and tried to compile a ConTeXt project, but this failed: texexec --pdf --mode=editor --once ../products/prd_book.tex resolvers | caches | path '/Users/gerben/Library/texlive/2013/texmf-var' created/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require': /usr/local/texlive/2013/texmf-dist/scripts/context/ruby/base/switch.rb:501: invalid multibyte escape: /\xFF/ (SyntaxError) from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require' from /usr/local/texlive/2013/texmf-dist/scripts/context/ruby/texexec.rb:11:in `<main>' It seems a problem in a ruby file in MacTeX 2013. Can someone help me get this working? Thanks, G

section numbers in margin eventually get placed too far left
by Sanjoy Mahajan 18 Sep '13

18 Sep '13

This test file ================================================== \setuplayout[leftmargindistance=0.125in, leftmargin=0.625in, width=4.75in, rightmargindistance=0.25in, rightmargin=0.25in] \setuphead[section][alternative=inmargin] \showframe \starttext \dorecurse{6}{\section{Blah} \input tufte } \stoptext ================================================== asks for section numbers in the left margin, separated from the section title by the leftmargindistance. It works fine for the first four sections. But sections 5 and 6 (on page 2) have the section number shifted further left from the correct position by roughly 10pt or so. It seems very sensitive to the layout. If I change the leftmargindistance to 0.25in, the section numbers are all placed correctly. I noticed the problem on my default context version: ConTeXt ver: 2013.05.28 00:36 MKIV current [from the Debian TL2013 pkgs] It also happens with the live ConTeXt and with vanilla TL2013. (Though it works fine with MKII.) Is this a bug, or just a change in setuphead that I didn't take account of? -Sanjoy

Difference between base and third
by john Culleton 17 Sep '13

17 Sep '13

I note that in texlive 2013 the typescripts are found in two subdirectories, "base" and "third". Is there a reason for this subdivision or is it just an accident of history? -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html PDF e-book: "Create Book Covers with Scribus" available at http://www.booklocker.com/books/4055.html

Bug in maths prime (derivative)
by Otared Kavian 17 Sep '13

17 Sep '13

Hi Hans, I noticed that recently a discrepancy in the way the prime is positioned in the presence of an index as in $f'_n$ or $f_n'$ (please see the attached PDF). However the positioning is correct in expressions such as $u^k_n$. The problem shows up only in mkiv, and as far as I can say the differnece between the results in mkii and mkiv appeared recently (unfortunately I can't say when…). %%%% begin minimal-example.tex \starttext \startbuffer[math] If for $n \geq 1$ we consider $f_{n} : {\Bbb R} \longrightarrow {\Bbb R}$ a real valued function, and $u_{n} : {\Bbb Z} \longrightarrow {\Bbb Z}$ then we denote \startformula f'_{n}(x) := \lim_{h\to 0}{f_{n}(x + h) - f_{n}(x) \over h}\qquad\mbox{and}\quad u^k_{n} := u_{n}(k) \stopformula \stopbuffer \getbuffer[math] \switchtobodyfont[times] \getbuffer[math] \switchtobodyfont[palatino] \getbuffer[math] \stoptext %%%% end minimal-example.tex
