Hi, In order to keep the 'context is good for toy math' reputation up to date, in lmtx we can now have proper discretionaries in math and math in discretionaries. The kind of things no one asks for but they might be useful in educational settings. Here are some examples (): \starttext \showframe \enabletrackers[math.toysymbol] \definemathtoysymbol[Plus] [bin][+] \definemathtoysymbol[Minus][bin][-] \definemathtoysymbol[Equal][rel][=] $\dorecurse{199} { x_{#1} \ifodd#1\relax\Plus\else\Minus\fi } x_{200} \Equal n$ \blank \dorecurse{10} { test \discretionary {\darkred hel $\sqrt{y}$ lo} {\darkgreen good $\sqrt{z}$ bye} {\darkblue wel $\sqrt{x}$ come} test } \blank \dorecurse{10} {test me #1 $x + 2x \discretionary class 2 {$+ \, \cdots $} {$ \cdots \, +$} {$+ \, \cdots \, +$} nx$ test } \stoptext You might be able to guess from this code what is supposed to happen. I'll play a bit more with this later (assuming that it's somehow useful). We could predefine a bunch. As usual there might be issues but I'll sort them out when we run into them (it's a non critical feature with not much impact).

Hi, Hans. :) Is there an analogue for display math? Could discretionaries be applicable to math formulas when "split=yes" is enabled, for instance? Thank you in advance. Jairo :) El lun., 31 de ago. de 2020 a la(s) 15:21, Hans Hagen (j.hagen@xs4all.nl) escribió:

can you give an example of usage Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
