Notation of the first derivative in mathematical mode (lmtx)
by Fabrice Couvreur 03 Aug '20

03 Aug '20

Hello, I replaced the context engine with the lmtx engine but I find that the derivative symbol is too high regardless of the font used. I mainly use modern and pagella because I type many texts using mathematics: can we correct this problem, Thanks for your help. Fabrice \starttext \startitemize[n] \startitem \math{f'(x)=x²+4x+4} \stopitem \startitem \math{f''(x)=2x+4} \stopitem \stopitemize \stoptext

consistent index entries
by Henning Hraban Ramm 01 Aug '20

01 Aug '20

Hi, besides the CG journal I’m working on a scientific biography with huge person and locality indexes (named Person and Locality for the examples). In many cases, the author wants additional information in the index, e.g. \Locality{Altona (Hamburg)} \Locallity{Breslau (pol. Wrocław)} or \Person{Arends, Katharina (née Schoemaker)} \Person{Wilhelm II. (Kaiser)} Now, I need that consistent and I don’t want to type these complicated entries every time. I’m looking for a good way to handle this – maybe a lookup table in Lua, so that \LookupPerson{Willy II} would call a Lua function that returns \Person{Wilhelm II. (Kaiser)} ? Or is there already something in place that I overlooked, like \OverwriteIndexEntry{Hraban}{Ramm, Henning Hraban} ? Hraban

handle_error_hook in LuaMetaTeX
by Marcel Fabian Krüger 01 Aug '20

Hi, thanks for handling f file consition in LuaMetaTeX. While playing with that, I encountered a potential bug in the latest LuaMetaTeX version: If handle_error_hook is executed and returns any number, LuaMetaTeX segfaults. (I'm pretty sure that this still worked with the previous version) Minimal ConTeXt example: \enabledirectives[system.quitonerror=false] \directlua{ print(callbacks.register('handle_error_hook', function(...) return 3 end)) } \undefined % Trigger an error \starttext \stoptext This triggers [...] system > ConTeXt ver: 2020.07.31 10:20 LMTX fmt: 2020.7.31 int: english/english [...] tex error > tex error on line 7 in file ./test_empty_input.tex: !

About testing rest of space on a page
by Willi Egger 30 Jul '20

30 Jul '20

Good evening! I have a bookproject in which sections are ended with a small graphical element. Now as usual this graphic might be moved to a new page which is of course unwanted. At this moment I have: \startsetups endsection \vfil \placefigure[middle,none][]{}{\externalfigure[ornament2][height=2\lineheight]} \stopsection \stopsetups \def\stopmysection{\setups{endsection}} I use then instead of \stopsection the \stopmysection. This works except that the ornament is in some cases placed on the next page. — My question is whether it is possible to do a \testpage and evaluate the result hereof and then using either the placement of the ornament and stop the section or just end the section without ornament? Kind regards Willi
