[NTG-context] Something broke between 2021.07.23 and 2021.08.19
I re-processed a previous issue of a journal and found that it no longer compiled. It worked fine in versions up to and including 2021.07.23 but fails by version 2021.08.19 19:48. It may have failed a little earlier than this - I don't always refresh every release. The error in the console log is: [...] open source > level 2, order 9, name 'covers/inside-front-cover.tex' tex error > tex error on line 24 in file covers/inside-front-cover.tex: lua error: registered function call [396]: ...-64/tex/texmf-context/tex/context/base/mkxl/anch-pos.lmt:1286: attempt to call a nil value (upvalue 'texgetparstate') stack traceback: ...-64/tex/texmf-context/tex/context/base/mkxl/anch-pos.lmt:1286: in function <...-64/tex/texmf-context/tex/context/base/mkxl/anch-pos.lmt:1262> (...tail calls...) [...] Unfortunately I can't create an MWE any smaller than a project with about 3 sub-directories and half a dozen files. I don't really want to post it all here but happy to send a zip to Hans. (When it works it only creates a two page PDF so 'minimal' in that sense.) Secondly, something a bit specific to Macos also broke for the latest version. Previously I had: \definefont [RPN] [Menlo*bold at 12pt] but had to change that to \definefont [RPN][file:Menlo.ttc at 12pt] to get it compile. I thought it was something odd about Menlo (which is a Macos system font) at first which is why I changed to using the name: syntax but when this other problem came up I realised it too had worked previously. — Bruce Horrocks Hampshire, UK ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___

Hi again,
Many thanks to Hans and Hans and Henri.
The solution (going to low level) provided by Hans works fine.

Re: [NTG-context] Curiosity about math.random in LuaTeX
I guess the underlying library calls are from Lua5.4? Then it is perhaps useful
to know that between 5.3 and 5.4 there is mentioned a new implementation for
math.random. Perhaps it changes the sequence of random values generated?
Someone who knows?

You can immediately forget about that, because in the past Lua has switched the random number generator (RNG) between releases and also uses a different RNG depending on the operating system. In general it is a really bad idea to depend on the exact sequence of random numbers. As an alternative you can just pregenerate a list of random numbers and copy that to other documents.

Hi everybody.
I wonder how does math.random() work in context. I found that this subject was
discussed more than ten years ago by Otared and Taco and Thomas. It is clear to
me how to obtain new results upon typesetting the same file by changing the
value of math.randomseed (with os.time()).
If you don't change the seed, you get the same result upon each typesetting,
and a seed is given in the .tuc file.
For example I have this:
["randomseed"]=0x1.0741c18b8a4ep-6
How do I use (and is it possible to) this value to have the same result of
math.random() upon typesetting another file (with a different name) ?
I could provide a same fixed seed in both files, but for some reasons I would
like to re-use some previous results of math.random() for which no seed was
initially given in another .tex file.
You have to go low level ...
% \ctxlua{utilities.randomizer.setseed(0x1.0741c18b8a4ep-6)}
% \ctxlua{utilities.randomizer.setseed(0x1.6822232009d5p-5)}
\setrandomseed{123}
\starttext
test \randomnumber{1}{100}
test \randomnumber{1}{100}
test \randomnumber{1}{100}
\stoptext
btw, the 0x representation is lua's low level binary representation of a
double.

[NTG-context] Bug with mathalignment and columns
Hi,
When a mathalignment is started at the end of a multi-column page ConTeXt
places it at the start of the previous second column instead of placing it on a
new page. Here's my code to test:
\starttext \startcolumns[n=4]
\startluacode
lorum = "Lorum ipsum dolor sit amet. "
for i = 1, 98, 1 do
context(lorum)
end
\stopluacode
\startformula \startmathalignment[n=1]
\NC y = ax \NR
\NC a^2 + b^2 = c^2 \NR
\NC x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \NR
\stopmathalignment \stopformula
\stopcolumns \stoptext
Adding text after the formula seems to fix the issue, but that means I can't
finish the page with a formula.
It seems that it always places the formula at the top of the second column,
regardless of how many columns there are.
It also does this even if there are still empty columns (try changing 98 to 100
in the for loop).

Re: [NTG-context] Curiosity about math.random in LuaTeX
Hi everybody. I wonder how does math.random() work in context. I found that this subject was discussed more than ten years ago by Otared and Taco and Thomas. It is clear to me how to obtain new results upon typesetting the same file by changing the value of math.randomseed (with os.time()). If you don't change the seed, you get the same result upon each typesetting, and a seed is given in the .tuc file. For example I have this: ["randomseed"]=0x1.0741c18b8a4ep-6 How do I use (and is it possible to) this value to have the same result of math.random() upon typesetting another file (with a different name) ? I could provide a same fixed seed in both files, but for some reasons I would like to re-use some previous results of math.random() for which no seed was initially given in another .tex file.

Re: [NTG-context] lmtx update/t-vim (again)
This is the setup I have been using, but I'm unsure if the problem could be
related to the other problem I had. (Not scaled to a MWE, but short enough.) I
figured the issue by removing some of the lines.
\usemodule[vim]
\definetextbackground[codebkg]
[
frame=on,
framecolor=black,
background=,
location=paragraph,
]
\definevimtyping[vimR]
[
syntax=r,
space=off,
lines=split,
numbering=yes,
numberstep=5,
alternative=pscolor,
margin=.5em,
style={\switchtobodyfont[type,small]\setupinterlinespace},
before={\blank[white,small]\startcodebkg}, % a bit of extra space
after={\stopcodebkg},
directory=vimout/, % note: you must create this folder yourself!
]
\starttext
\startvimR
#!/usr/bin/env R
included_aa <- list(
`6d1t` = 2:81,
`6cnq` = 146:225,
`6ccg` = 2:81,
`4lg7` = 76:167,
`3c2i` = 90:181) %>% enframe() %>% unnest(cols = "value") %>%
rename(protein = "name", aa_pos = "value") %>%
mutate(chain = "A") %>% mutate(include_aa = TRUE)
\stopvimR
\stoptext
So, the first "i", "n" etc. come from "include_aa" after I remove the shebang
statement.
The lines with "#" and "$" (in other pieces not shown) cause the complaints.
I also realized that I get output for each vim block, but instead of a
"vimout", I get a "pdf" (error) and a "log" (some attached) now.
Also, the blocks get recompiled with each run even if their content doesn't
change which was the previous behavior.
