Error when running context --make after updating context (FreeBSD)

Hi folks, I receive the following error when running context --make command (after update via install.sh): lua error > lua error on line 18 in file file-mod.mklx: token call, execute: ...ext/tex/texmf-context/tex/context/base/mkxl/file-mod.lmt:78: attempt to call a nil value (field 'getrunstate') stack traceback: ...ext/tex/texmf-context/tex/context/base/mkxl/file-mod.lmt:78: in local 'code' ...ext/tex/texmf-context/tex/context/base/mkiv/util-lua.lua:97: in field 'loadedluacode' ...ext/tex/texmf-context/tex/context/base/mkiv/luat-env.lua:108: in field 'luafilechunk' ...ext/tex/texmf-context/tex/context/base/mkxl/luat-cod.lmt:82: in function 'lua.registercode' [ctxlua]:1: in main chunk <empty file> A number should have been here; I inserted '0'. (If you can't figure out why I needed to see a number, look up 'weird error' in the index to The TeXbook.) Any clues as to what causes this error? System is FreeBSD 14.2 TIA and regards, PT

does \setuplayout[grid=yes] require \startformula[split=line] ?
by garulfo＠azules.eu 28 Jan '25

28 Jan '25

Hi, sorry for the potentially puzzling title. I try to figure out why \setuplayout[grid=yes] seems to insert a line break in a short formula. Is there a way of ensuring regular vertical alignment of the formula number without ‘split=line’ ? Many thanks for your help. %%% START \setuppapersize[A6,landscape] \enabletrackers[math.showmargins.less] \startsetups[math:penalties:mathincontext] \shapingpenaltiesmode \zerocount \widowpenalties 3 5000 250 100 \clubpenalties 3 5000 250 100 \stopsetups \setupformula [split=mathincontext] \starttext Text \startplaceformula \startformula c^2 = a^2 + b^2 \stopformula \stopplaceformula \setuplayout[grid=yes] \page Text \startplaceformula \startformula c^2 = a^2 + b^2 \stopformula \stopplaceformula \page Text \startplaceformula \startformula[split=line,numberlocation=overlay] c^2 = a^2 + b^2 \stopformula \stopplaceformula \disabletrackers[math.showmargins.less] \stoptext %%% END

Is this the expected behaviour? From an observation from https://wiki.contextgarden.net/Text_blocks/Environments/Quotes#Directly \starttext \quote{Some text} \setupdelimitedtext [quote] [color=red] \quote{Some text} \setupdelimitedtext [quote] [symcolor=red] \quote{Some text} \stoptext

What would be the simple preferred way to define a document having not just odd and even pages but also alternating width is sets of two. e.g. two pages with width 118 mm followed by two pages of 178 mm followed by two pages with width 118 mm, ... all hints appreciated .Floris

How to load external lua library
by krulis.tomas＠seznam.cz 25 Jan '25

25 Jan '25

Dear ConTeXt mailing list, I've been struggling with loading the sqlite external lua library. I tried the following: 1. Instaling the system package and running ConTeXt with the `--permitloadlib` option (I am running Manjaro, an arch-linux derivative: https://archlinux.org/packages/core/x86_64/sqlite/) 2. Installing the luarocks package (https://luarocks.org/modules/dougcurrie/lsqlite3) for the 5.1, 5.3 and 5.4 lua versions. I also tried to symlink the files in $HOME/.luarocks/lib/lua/{version}/lsqlite3.so to the project directory 3. I tried also setting the relevant lua paths with `eval $(luarocks path)`. The compilation always fails with an error that context can't locate the sqlite3 library. How can I load data from sqlite database during context compilation? As an MWE, I am adding the example in the documentation for the interaction with sqlite from the context garden (https://www.pragma-ade.nl/general/manuals/sql-mkiv.pdf) ```tex \starttext \startluacode require("util-sql") utilities.sql.setmethod("sqlite") require("util-sql-loggers") local loggers = utilities.sql.loggers local presets = { -- method = "sqlite", database = "loggertest", datatable = "loggers", id = "loggers", } os.remove("loggertest.db") -- start fresh local db = loggers.createdb(presets) loggers.save(db, { -- variant 1: data subtable type = "error", action = "process", data = { filename = "test-1", message = "whatever a" } } ) loggers.save(db, { -- variant 2: flat table type = "warning", action = "process", filename = "test-2", message = "whatever b" } ) local result = loggers.collect(db, { start = { day = 1, month = 1, year = 2016, }, stop = { day = 31, month = 12, year = 2116, }, limit = 1000000, -- type = "error", action = "process" }) context.starttabulate { "||||||" } for i=1,#result do local r = result[i] context.NC() context(r.time) context.NC() context(r.type) context.NC() context(r.action) if r.data then context.NC() context(r.data.filename) context.NC() context(r.data.message) else context.NC() context.NC() end context.NC() context.NR() end context.stoptabulate() -- local result = loggers.cleanup(db, { -- before = { -- day = 1, -- month = 1, -- year = 2117, -- }, -- }) \stopluacode \stoptext ``` I am sorry for the poor quality of the example, but I don't know how to add an attachment to a message in a mailing list. I have found a few references on the web and on this mailing list (https://mailman.ntg.nl/archives/list/ntg-context@ntg.nl/message/IDZBJQIXG3J…) but I wasn't able to figure out what I could be doing wrong. I found a reference that the issue might be a version mismatch, so I tested multiple lua versions. My project is about using multiple data sources in multiple formats and creating reports from them. I know I will definitely need to load YAML as well (with the `lyaml` luarocks package I guess). There's always the alternative of trying to use other programs to get the data, but I was wondering if I could leverage ConTeXt to do that directly. Thank you for any guidance on this, and I hope this message is not too long ...

Decreasing size of the section number according to its level
by garulfo＠azules.eu 24 Jan '25

24 Jan '25

Hi, in setuphead, I try to get a decreasing size of the section number according to its level with \defineconversion and \definestructureconversionset. It works as expected for the first levels, but between 6th and 7th, the variation doesn't occur. Any clue about what is happening ? For the MVE, I've added a visual check in dark red to show the discrepancy. \setuppapersize[A5] \define[1]\NivA{\tfc #1} \defineconversion[NA][\NivA] \define[1]\NivB{\tfb #1} \defineconversion[NB][\NivB] \define[1]\NivC{\tfa #1} \defineconversion[NC][\NivC] \define[1]\NivD{\tf #1} \defineconversion[ND][\NivD] \define[1]\NivE{\tfx #1} \defineconversion[ND][\NivE] \definestructureconversionset [mysectionnumbers] [N,N,NA,NB,NC,ND,NE] [N] \definestructureconversionset [mysectionnumbersforlist] [N] [N] \setupheads [sectionconversionset=mysectionnumbers] \setuplist [section, subsection, subsubsection, subsubsubsection, subsubsubsubsection] [numberconversionset=mysectionnumbersforlist] \starttext \placecontent \startsection [title={Section}] \startsubsection [title={SubSection}] \startsubsubsection [title={SubSubSection}] \startsubsubsubsection [title={SubSubSubSection}] \startsubsubsubsubsection [title={SubSubSubSubSection}] \stopsubsubsubsubsection \stopsubsubsubsection \stopsubsubsection \stopsubsection \stopsection \color[darkred]{{\tfc 1.}{\tfb 1.}{\tfa 1.}{\tf 1.}{\tfx 1}} \stoptext

Problem using Neo Euler in slides

Dear List, I am using the Debian ConTeXt with the following version: context 2024.04.01.20240428+dfsg-2 I am having some issues, particularly with the \sqrt symbol when using a presentation mode in ConTeXt. The following gist has the files in question: https://gist.github.com/kumanna/eb81deae66e34809b9074be1f3f6e9d0 I have the Fontin, Neo Euler and Delicious OTFs loaded properly with mtxrun.
