Re: [NTG-context] math symbol for "is an element of"
Thank you, Hans! The links you gave me provide me with another useful tool in my toolbox (which I had not been aware of before). In this particular case, as Wolfgang pointed out, \in actually does work to get the desired symbol in math mode. But it is good to know how to use text substitutions too.

Re: [NTG-context] math symbol for "is an element of"
My sincere apologies. I tried to do my homework to avoid wasting everybody
else's time with a silly question, but apparently I did not do so adequately.
You're quite right -- it works with no problem. It was something else nearby
that was causing my minimal example (apparently not minimal enough) to fail.
That being said, the link to "\in" on the Math Basics page does point to the
wrong place (the "\in" command used for references). I'll go correct that as my
penance for asking such a ridiculous question.
Thanks, and again my apologies,
Sciurus

[NTG-context] MP background for text typeset by \typefile
Hello,
is there a way to draw custom background (via MP) to a text typed by
\typefile, which is so long so it spreads over more pages?
- I'm asking because I know how to typeset some text via \typefile with:
1. this:
\definetyping[Test]
[before={\startbackground[background=color,backgroundcolor=blue]
},
after={\stopbackground
},
]
- which creates a rectangular backround to the text, and the text may
spread over pages;
2. or this:
\defineoverlay[AnOverlayDefinition][]
\definetyping[Test]
[before={\startframedtext[background=AnOverlayDefinition,
]%
},
after={\stopframedtext
},
]
- which allows to define a custom background via overlay/MP, but which
encloses the text to be typeset into a framed, and thus doesn't spread
over pages.
My intention is to "decore" the text typed by \typefile with a "fuzzy"
background, which uses overlay/MP.
But I am in the sitaution where I am able to figure out MP code just
when the text is to be enclosed into \framed.
Is it possible to combine both cases? How?
Best regards,
Lukas

Hi Sylvain, on my computer (TL2020) I am not able to compile \blank with any command defining the dimension (2\paperheight, 0.25\paperheight, .25\paperheight). I do not know why...

Removing tex/texmf-cache does not help. Removing firefoxe does ... when I open e.g. the cnn website in firefox (for instance to keep an eye on crazy elections), that program takes 650 MB memory and 44% GPU while edge (or chrome) takes 270 MB mem and 3% GPU. Add a few more tabs and firefox will easily eat up gigs of mem. Now, I don't know how it manages memory but the tex engine needs a few reasonable sized arrays but in large allocs and then it manages its own memory from that pool, Lua needs more mem (could be scattered due to allocs i guess), and soem garbage collection can kick in, and browsers ... well i suppose lots of allocations and it also depends on the jasvascript vm. So, I would not be surprised if after some runs of these programs you end up with scattered memory. I suppose that at some point the operating system (when in rest) will sort things out. When I make a format file it normally takes a few seconds. When I let firefox run wild on memory (top out mem and then let it give back some), it can take twice as much to make a format, but after quitting firefox it's all ok again. Anyway, already long ago I decided that firefox is a memory hog so whenever I do something that takes more time than I susspect, I close firefox. Actually I often close browsers when i don't need them, also because they always seem to be busy with something (also the network). Tex is just juggling some bytes. In the past tex and distributioen were considered large ... nowadays they are small compared to whatever you install and run. And in luametatex/context the performance bottleneck is lua, not the core tex engine. Of course you could consider swithcing to another operating system.

[NTG-context] Why is the textarea not centered by default?
Dear List, \starttext \showframe \showsetups \stoptext This minimal example without further configuration shows that the default value for backspace, textwidth and paperwidth are 2.5cm, 15cm, 21cm resp., which means that the textarea is horizontally 0.5cm off the center by default, and one can indeed see a clear extra margin on the right side. This seems weird but I'm no expert of typesetting, so does anyone know why it has been set like that? Thanks.

[NTG-context] What is "cutspace" and "bottomspace"?
Dear List, according to https://wiki.contextgarden.net/Command/setuplayout , "cutspace" and "bottomspace" are the counterparts of "backspace" and "topspace", and "If cutspace is set to 0, it is taken to be equal to the backspace". But in fact, the following document stays the same no matter what value is given to cutspace. \setuplayout[cutspace=0.01cm] \starttext x \showframe \stoptext Has anyone actually used these two parameters?
