Math kerning broken in latest beta
by Henri Menke 11 Apr '18

11 Apr '18

Dear list, The math kerning seems to be broken in recent versions of LuaTeX. When I process the MWE below with TeX Live 2017 (LuaTeX 1.0.4) I get a different result from the latest beta (LuaTeX 1.07.0). However, I could only observe this behaviour with some fonts, e.g. stixtwo or lucidaot. No difference was encountered for modern and xits. Cheers, Henri --- \setupbodyfont[stixtwo] % or lucidaot \startTEXpage $V_A$ \stopTEXpage

xmlrefatt
by dr. Hans van der Meer 10 Apr '18

10 Apr '18

There is a slight restriction on \xmlrefatt that makes its use problematic, because it does not differentiate between an absent attribute and an attribute consisting of an empty string. The use for \xmlrefatt I had in mind was (a) do nothing if the attribute is absent, and (b) reset some value to its default value when the attribute is present but an empty string. Is it an option that its implementation is changed? A boolean return value will be fine, because false then can signify the attribute’s absence and true its presence. In the latter case it is safe to retrieve the attribute which then might be an empty string. Summarizing: the fact that \xmlrefatt tries to do two different things at the same time (signalling presence/absence) and returning an attribute, in a certain sense cripples its use. dr.

how to change the colour of the footnote marker
by Robert Zydenbos 10 Apr '18

10 Apr '18

Today I wanted to print an entire document not in standard black, but in blue. I added (Mk II) – \setupcolors [state=start] \define\kleur{blue} % so I can change the colour uniformly everywhere through this variable \startcolor [\kleur] \setupnote[footnote][before={\color[\kleur]}] \setupfooter [color=\kleur] – and everything becomes blue, but NOT the footnote number before the footnote itself at the bottom of the page (the marker in the main text is coloured the way I want). Can anyone tell me how to change the colour of the footnote number in the note? Robert

Text overflowing on a figure included in a float

\blank shrinks when forced; why \blank[line,disable] and \blank[line]\blank[disable] are different?
by mf 08 Apr '18

08 Apr '18

Hello list, i'm trying to understand the \blank command. The following example leaves a blank line between the two lines of text. \showgrid \starttext A line.\par \blank[line] Another line.\par \stoptext When you add "force" to the blank, the vertical space between the two lines shrinks. You can also add "fixed", but nothing changes. \showgrid \starttext A line.\par \blank[line,force] Another line.\par \stoptext Wolfgang asked about this in 2015(https://www.mail-archive.com/ntg-cont ext(a)ntg.nl/msg77729.html) but i could not find any answer on the mailing list. The next doubt is about the "disable" option. In the following example, \blank[2*line] wins over \blank[line] because it's bigger, and you get a vertical space of 2 lines between the 2 lines of text. \showgrid \starttext A line.\par \blank[line]\blank[2*line] Another line.\par \stoptext Then add "disable" to the first blank to cancel the next one: \showgrid \starttext A line.\par \blank[line,disable]\blank[2*line] Another line.\par \stoptext I expected a vertical space of 1 line, instead there's none. Why? Conversely, this disables the second \blank, as you would expect: \showgrid \starttext A line.\par \blank[line]\blank[disable]\blank[2*line] Another line.\par \stoptext Best greetings, Massimiliano

Wrong section space after placefigure with newcolumnsets
by Charles Vejnar 06 Apr '18

06 Apr '18

Hi, I am placing figures in a columnset. The next header (section, subsection...) following the figure has always missing vertical space. See the normal space after "One subsection" and "Four subsection" but reduced space after "Two subsection" and "Three subsection" in the example below. Tested with ConTeXt ver: 2018.04.04 and LuaTeX, Version 1.07.0. This seems to be the opposite problem as the one described recently in the thread "Bug in wrapped placefigure". Any solution or fix? Thank you very much for your help.
