typo in publications-customized.tex

Hello, I found a typo in publications-customize.tex. Here is a diff -u that may help to fix it quickly (not used to sending diff, I hope it'll help) --- publications-customize-patched.tex Mon Oct 28 07:26:37 2019 +++ publications-customize.tex Mon Oct 21 13:56:04 2019 @@ -362,7 +362,7 @@ diagnostics as described in the Appendices. Their functional meaning is rather \quote {handled} in contrast to \index {field+ignored}\quote {ignored}. \stopfootnote Note that if a category is \emphasis {not} declared in this \LUA\ -table, then \emphasis {all} of its fields will be considered \index +table, than \emphasis {all} of its fields will be considered \index {field+optional}\quote {optional}. Thus, ignoring this level of control and simply defining additional setups might be sufficient for most use. Regards, Damien Thiriet

cm unicode font: missing tounicode of oldstyle nums
by Ulrike Fischer 27 Oct '19

27 Oct '19

cmunrm.otf uses "unstandard" names for the glyphs of the old style numbers, e.g. oneoldstyle. This means that the glyphs don't get a tounicode mapping: \starttext \pdfvariable compresslevel=0 \font\test={file:cmunrm.otf:mode=node;script=latn;language=DFLT;+onum;}\test abc123 \stoptext gives 6 beginbfchar <0042> <0061> <0043> <0062> <0044> <0063> <0874> <FFFD> <0875> <FFFD> <0876> <FFFD> endbfchar The names are in glyphtounicode.tex, which contains e.g. \pdfglyphtounicode{oneoldstyle}{0031} So it doesn't looks as if they were completly unusual. Would it be possible to add tounicode mappings for these name? And how can one declare mappings for really unusual names? -- Ulrike Fischer https://www.troubleshooting-tex.de/

interlaced overbrace and underbrace
by mf 25 Oct '19

25 Oct '19

Hello list, is there a better way to interlace overbraces and underbraces like this? \starttext These are the expressions to combine: $$\overbrace{a+b+c}+d \quad a+\underbrace{b+c+d}$$ This is the desired result: $$\overbrace{a+b+c}+d \kern-16mm\underbrace{\hbox to 15mm{ }}$$ \blank {\tfx(the underbrace should move down a little more)} \stoptext TIA, Massi

place single entry of a register, or filtering the terms of a register
by mf 25 Oct '19

25 Oct '19

Hello list, is there a way to place only one single entry of a register, or a selection of entries? I looked into strc-reg.mkiv and strc-reg.lua and i would answer "no, it's not possible". I could hack strc-reg.lua and define a command to do that, but maybe a better solution is already there. Here's a very simple MWE to work on, in case it's possible: \starttext Cat\index{cat}, mouse\index{mouse}. \page Cat\index{cat}, dog\index{dog}. \page \placeindex \page Here I'd like to place only the "cat" entry:\par \placeindex[criterium=???] \stoptext Massi

Luacode: Data File to Table
by Rudolf Bahr 24 Oct '19

24 Oct '19

Hi All! LuaMetaTeX, Version 2.00.0 ConTeXt ver: 2019.10.10 18:15 MKIV beta fmt: 2019.10.19 int: english/english I'd like to transfer the entries in a data file to a Lua table according to [1]. Here a MWE of my data file, appended as file Rosi.lua: -------------------------- Rosi{ smrk = "00-003", picture_file = "/home/sam/pictures/", picture_name = "00-003---1981---Provence.png", width_px = "394", height_px = "481", } Rosi{ smrk = "00-006", picture_file = "/home/sam/pictures/", picture_name = "00-006---1986---Eire.png", width_px = "392", height_px = "479", } And here is my MWE in Luacode: ------------------------------ \startluacode userdata = userdata or {} u = userdata function u.Hugo ( ) local S = {} function Rosi (b) S [ b.smrk ] = { [ "smrk" ] = b.smrk, [ "picture_file" ] = b.picture_file, [ "picture_name" ] = b.picture_name, [ "width_px" ] = b.width_px, [ "height_px" ] = b.height_px, } context ( 'function Rosi(): b.smrk = ', b.smrk ) context.par() end require ("Rosi") end \stopluacode \starttext \currenttime \def\Heidi% {\ctxlua{u.Hugo()}} \Heidi \stoptext The entries in Rosi.lua aren't recognized in Luacode! The output pdf is appended as well. Now the essential part of the MWE above in pure Lua. Here it works! Strange. ----------- userdata = userdata or {} u = userdata function u.Hugo ( ) S = {} function Rosi (b) S [ b.smrk ] = { [ "smrk" ] = b.smrk, [ "picture_file" ] = b.picture_file, [ "picture_name" ] = b.picture_name, [ "width_px" ] = b.width_px, [ "height_px" ] = b.height_px, } print ( "b.smrk = " .. b.smrk ) end require ("Rosi") print ( S["00-003"]["width_px"], S["00-003"]["height_px"] ) print ( S["00-006"]["width_px"], S["00-006"]["height_px"] ) end u.Hugo () Please, what could be done?

Surprising change in function inspect()

Hi all, using the source code ====== \starttext \startluacode d={} d.data={"a",0} d.tabulka=function () context("pokus") end inspect(d) d.tabulka() \stopluacode pokus \stoptext ====== I discovered quite surprising change in the output of inspect: TL2019: table={ ["data"]={ "a", 0 }, } TL2018 and older: table={ ["data"]={ "a", 0 }, ["tabulka"]=load("\27LuaR\0\1\4\4\4\8\0\25�\13\ \26\ \4\0\0\0\4\0\0\0\0\0\2\4\0\0\0\6\0@\0A@\0\0\29@\0\1\31\0�\0\2\0\0\0\4\8\0\0\0context\0\4\6\0\0\0pokus\0\0\0\0\0\1\0\0\0\0\0\14\0\0\0=[\\directlua]\0\4\0\0\0\4\0\0\0\4\0\0\0\4\0\0\0\4\0\0\0\0\0\0\0\1\0\0\0\5\0\0\0_ENV\0"), } Is there any way how to persuade the current inspect to add functions to the output as before?

Re: [NTG-context] [NTG-CONTEXT] LTMX crashes on OpenBSD 6.5 amd64
by Damien Thiriet 21 Oct '19

21 Oct '19

Hello, I tried a system-wide install of luametatex, but having my binaries in a disk mounted with w^xallowed did not change anything. I tried to compile different files, but cannot guess yet where do the crash come from. If it can help, I uploaded the luametatex.core file and files that were compiled during the crash at this adress: http://www.normalesup.org/~dthiriet/luametatex/ When I compiled this file, I had the first crash at page 12. Retrying to compile made it crash at page 3. I did not wipe the cache between compilations, nor made mtxrun --generate and context --make. Thanks, Damien Thiriet

luametatex install as root in OpenBSD
by Damien Thiriet 21 Oct '19

21 Oct '19

Hello, When I installed luametatex as root under OpenBSD amd64 this morning, I first had "no permission" to launch context. So I checked my /usr/local/context file (where I unpacked the zip). The symlink context had the right permissions after install process (-rwxr-xr-x root wheel) but not luametatex. I changed permissions for luametatex to -rwxr-xr-x root wheel but maybe it should be introduced at install script level? Btw, context.lua and mtxrun.lua are both installed with permissions -rwxr--r-- root wheel Are those lua script only called by root? Should I change their permissions as well to -rwxr-xr-x? Greetings, Damien Thiriet
