So somehow in math the +onum is lost in plain and latex but not in context. What is context doing differently to avoid this?

mode=base

If context attach mode=base to math, how does it it? How can you switch a feature like mode=node to mode=base for every font in math?

that has to be done in otfload i guess (context does it in the featureset applied to math fonts) there is no node processing in math (when using base mode one ca apply some features like substitutions) that then gets passed to tex ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

A one would do in Luaotfload: specify base mode when defining the font. It’s unrelated to math, just the default set of features that Luaotfload has been applying to every definition for ages. The reasoning -- by Khaled and others -- was, that the Opentype standard mandates some defaults so Luaotfload should follow suit.

The defaults can be overridden by setting the appropriate values in luaotfload.conf(5).

Define two fonts: one for use in math mode, another for where you really, really require node mode.

Ulrike, thanks a lot for keeping asking questions on this and Philipp for answering. I have figured experimentally that I could use (at least in some cases, and after math fonts are initialized which in LaTeX seems to mean one needs to enter math mode at least once before) \font\fixmath=\fontname\textfont\foo mode=base; \textfont\foo=\fixmath for example creating this \fontname: [Vollkorn-Regular]:mode=node;script=latn;language=DFLT;+tlig;+lnum;mode=base; which is then experimentally observed to obey the second mode specifier and thus does display lining figures in math mode.

\font\fixmath=\fontname\textfont\foo mode=base; \textfont\foo=\fixmath

I will use a better approach as this one does not work when the thing ends as "at 7.0pt" for example, but in principle I see I can do surgery on the \fontname and replace there mode=node if it exists with mode=base.

I only have to figure out the best time to do that in a context (no pun intended) where people may change "\mathversion" (latex thing).

\begingroup \catcode`N 12 \catcode`O 12 \catcode`D 12 \catcode`E 12 \lowercase{\gdef\FixMathFont@i #1=NODE;#2\relax #3}% {\font\fixmath=#1=base;#2\relax\global#3\symmtoperatorfont=\fixmath} \endgroup \def\FixMathFont {\setbox0\hbox{\MTeverymathoff$\relax$% \expandafter\FixMathFont@i\fontname\textfont\symmtoperatorfont\relax\textfont \expandafter\FixMathFont@i\fontname\scriptfont\symmtoperatorfont\relax\scriptfont \expandafter\FixMathFont@i\fontname\scriptscriptfont\symmtoperatorfont\relax\scriptscriptfont}% } I only need to add the layer to do nothing if "=node" is not found, and we are allset.

Hi Jean-Pierre, You ahve done a wonderful job, thanks for sharing. I’ll look on a regular basis your wikibook and let you know if I find typos and examples to improve. Best regards: Otared K.

Dear French ConTeXt users (and others),

I have started to compile ConTeXt documentation in French, gathered in a Wikibook (Wikilivre) that you can find here : https://fr.wikibooks.org/wiki/ConTeXt. The whole documentation in this Wikibook is mostly given through French translations of original English documentation, which is provided by ConTeXt Garden wiki pages, Stack Exchange pages devoted to ConTeXt, and Bertrand Lemasson website (http://lesfichesabebert.fr/index.php/FichesBebert/Context), and by personnal tests made by me on both Linux/Windows systems.

This is a work in progress, and I need some help, first to correct the several code examples I give in this Wikibook, second to provide some examples of ConTeXt "critic apparatus" (in the way you can find in LaTeX code 'reledmac' there — thanks to Maïeul Rouquette — http://mirrors.ctan.org/macros/latex/contrib/reledmac/examples/1-criticalnot...), and third to give me some links where I can find ConTeXt up to date documentation (especially about complex book project). Of course, you may correct, improve and expand this project.

Thanks, JP Delange

That's easy if one can select the fonts explicitly, but the question was triggered by the url package which internally switches to math.

I have posted a (seemingly partial) patch to this problem of \url at http://tex.stackexchange.com/questions/264206/cant-get-oldstyle-figures-in-u...

as you don't specify a mode, you get base mode

Damn ;-). I didn't thought about this possibility. I assumed the default mode would be like in luaotfload "node". Thanks for correcting me. It is a relieve that I didn't find the font simply because it isn't there ;-). (Now I also understand Philipps remark ...) -- Ulrike Fischer http://www.troubleshooting-tex.de/
