[NTG-context] notes by paragraph
Re my earlier question on footnotes by defined paragraph: \start...stoplocalfootnotes and \placelocalfootnotes largely solves the issue (had forgotten that option), but I am still getting the footnotes repeated at the bottom of the page. I am obviously missing a setting. There are parts of this text that do require the usual footnotes at the bottom, so I would not want to turn off this option permanently. I have tried \setupnotation[footnote][display=no] but that is not working.

[NTG-context] footnotes by paragraph?
Here's a tricky one (for me) that I haven't been able to work out. I am
dealing with a set of constitutions that I am organizing with a
paragraph definition
\defineparagraphs[Two][n=2]
\setupparagraphs[Two][1][width=.2\textwidth,style=\bfx,after={\blank},align=flushleft]
\setupparagraphs[Two][2][width=.77\textwidth,style=normal,after={\blank}]
But I need to get the footnotes (which all apply to [2] in each article
of the constitutions) to come beneath my defined 'Two'. I do not want
them to come at the bottom of the page.
I thought I might be able to do it by placing \start...stopTwo within a
\start...stopsection and defining \setupnotation[way=bysection] but that
is not working.
Any thought on how I could approach this?
Julian

[NTG-context] Subject: Leading spaces verbatim
Good day to everyone, I'm trying to make a verbatim block of text with copiable leading spaces so that students can just copy my Python code snippets into their IDE. I believe the question has been asked before (though I confess I can't find the right search terms to find the answer again). I get that PDFs are not the optimal way to give code to students (which is why for longer snippets, I just give them the files or I attach them into the PDF), but for short snippets it would be so much simpler... I recently stumbled onto this article: https://www.overleaf.com/latex/examples/using-luatex-to-convert-interword-glue-to-spaces-and-kerns/sfdkdkybrvkv wherein the author replaces the TeX glue with spaces and kerning. I was wondering whether the same idea could be applied within the typing environment but making a primitive verbatim environment using \obeylines and \obeyspaces did not result in copiable spaces. Unfortunately, whilst I have some concepts of how luatex works on the input file, the step wherein a pdf is formed is fairly misterious to me, meaning I can't really understand the Lua code from said article (https://gist.github.com/Semptum/076cca71bc251ebe19ff96c5effca3cb). Hence, my three questions: - Is it even realistic to make such a typing environment? - What would be the best path to do so? - Can someone recommend some reading material specifically about this kind of typographical adjustments using LuaTex? Stuff like adjusting the glyphs's position, replacing characters with combined characters etc... Sorry if that's a bit vague, as you can see from the rest of the message, I never really went too deep into the later stages of the TeX pipeline.

True, but then there is still the problem with the number of
expansions. With a nested \directlua I always need at least two steps
to get the result from Lua.
\directlua{
function TestCmd()
tex.print("\string\\numexpr 17\string\\relax")
end
lua.get_functions_table()[999] = TestCmd
}
\let\:\expandafter % I'm lazy
\tt
\directlua{token.set_lua("test", 999)}
\:\def\:\x\:{\test}\meaning\x % macro:->\numexpr 17\relax
\protected\def\test{\directlua{TestCmd()}}
\:\def\:\x\:{\test}\meaning\x\par % macro:->\directlua {TestCmd()}

Thanks, this is indeed the workaround that I currently use. However,
the downside is that this has to tokenize the contents of \directlua
every time (and is therefore susceptible to surrounding \catcode
shenanigans) and it expands in at minimum two steps, whereas a luacall
always expands in a single step. But I guess that's what I will have to
live with.
