Hi, Question: does anyone rely on ~ being active and a nbsp in math mode?

How can I add “page # of ##” on my document ?
by Fabrice Couvreur 11 Aug '17

11 Aug '17

Hello, With Latex, I did this : \usepackage[colorlinks=true,pdfstartview=FitV,linkcolor=blue,citecolor=blue,urlcolor=blue]{hyperref} \rfoot{\scriptsize{\textsf{Page~\thepage{}~sur~\pageref{LastPage}}}} With Context, I tried this unsuccessfully ; \setupinteraction [state=start, style=, color=\darkred, contrastcolor=] \setuppagenumbering [alternative=, location={footer,right}, command={Page\,\pagenumber\,sur\,\lastpage } ] Thank you Fabrice

math font problem
by Alan Bowen 10 Aug '17

10 Aug '17

The aim is to get as much math using the Brill font as I can. I currently have: \definefontfamily[mainface][serif][Brill] %[TeX Gyre Termes] [protrusion=quality, expansion=quality, mode=node, force=yes, ] \definefallbackfamily[mainface][mm][TeX Gyre Pagella] [preset=math:digitsnormal,features=f:oldstyle,scale=0.94] \definefallbackfamily [mainface] [mm] [Brill] [preset=math:lowercasegreeknormal] \definefallbackfamily [mainface] [mm] [Brill] [preset=math:lowercasegreekitalic] \definefallbackfamily [mainface] [mm] [Brill] [preset=math:uppercasegreeknormal] \definefallbackfamily [mainface] [mm] [Brill] [preset=math:uppercasegreekitalic] \definefontfamily[mainface][mm][TeX Gyre Termes Math][scale=0.94] \setupmathematics[ucgreek=normal,lcgreek=italic] \setupbodyfont[mainface,10pt] \starttext 0123456789 math: \m{0123456789} δ\quad\emph{δ} math: \m{\delta} \m{δ}\quad should be slanted π\quad\emph{π} math: \m{\pi} \m{π}\quad should be upright but slanted will do Π\quad\emph{ Π} math: \m{\Pi} \m{ Π}\quad should be upright \m{2+2=4} \startformula \sin{α}={{ΑΒ}\over{AC}}=\sin{\alpha} \stopformula \stoptext Two problems: 1. I am not getting slanted lowercase Greek in mathmode. 2. I should like to have all the math lettering in the Brill font. But simply setting the Brill font as my math mainface runs into more problems—I still do not get lowercase Greek and it not only messes up 2+2 =4 , it also reports the error—Math error: parameter \Umathquad\displaystyle is not set—when it comes to the display math. My efforts to figure this out have not been successful thus far, so any suggestions will be most welcome. Alan

question for metapost experts
by Schmitz Thomas A. 10 Aug '17

10 Aug '17

Hi all, this one is for all the metapos/metafun experts out there (Alan, are you there?). For a counter in one of my slide backgrounds, I have to calculate an intersectionpoint, given in percentage of the difference between current page and last page. I have always had some difficulties on the first run, when the value of the last page isn’t known yet and hence not written to the tuc file, but the error > ! The paths don't intersect. > <to be read again> used to disappear in subsequent runs. Now, ConTeXt doesn’t compile the file at all and stops on this error. There is an error message I haven’t seen before: > intersectionpoint->...The paths don't intersect"); > origin.else:0.5[point.x_.o... > <to be read again> > ; > <*> ... ;z13 = (z11 -- z12) intersectionpoint qw ; > draw z13 withcolor (0.1,0.... > This error message was generated by an `errmessage' > command, so I can't give any explicit help. > Pretend that you're Miss Marple: Examine all clues, > and deduce the truth by inspired guesses. Is there a way to make this conditional, such as (pseudocode) if q intersects p: z = q intersectionpoint p ; else: z = (0,0) ; fi ; I hope that this would allow ConTeXt to proceed and calculate the point correctly on the second run. Thanks, and all best Thomas

\setupcombinations and the after-key
by Mathias Schickel 09 Aug '17

09 Aug '17

Dear List, it seems that the after key of the \setupcombinations-command is broken. I am not able to get zero space between the cells. I have attached a minimal example. Changing the after command does not have any effect at all. Mathias

BUG: Colour spilling in btxrendering
by Henri Menke 09 Aug '17

Dear list, I reported this already some time ago but apparently it went unnoticed. https://mailman.ntg.nl/pipermail/ntg-context/2016/086227.html When you place hyperlinks in the bibliography the colour »spills over«, see MWE below. The link is only on the string `Phys. Rev. 140 A1133–A1138 (1965)` but the whole line is coloured.

Using legacy math fonts
by Henri 09 Aug '17

Dear list, Because I don't like that Euler calligraphic script provided by Latin Modern Math, I want to revert to Computer Modern for the uppercase calligraphic letters. I got so far, that the command will produce the correct glyphs, however, the kerning is borken. What did I miss?
