@marmot Our discussion about clipping and the marmot transparency made thinking: tex.stackexchange.com/a/449947/36296 :)

marmot

@samcarter Very nice! +1. ;-)

^^^^ that's what I am just hoping to finish: closed 3D coil. trickier than I thought because of all the little rotations....

samcarter

@marmot Thanks :) The coil looks very nice! I can already imagine the marmot jumping through it. But now I'm back to bed.

marmot

@samcarter \pgfsetblendmode{multiply} is really smart

@samcarter @AlanMunn is in the news ;-)

@mico it's just that new users might take that the wrong way. I know it was a bad question, but most of the users don't read up on any of the guidelines on how to ask a question before posting their first. I read your comment and had to laugh, but it's a humor I developed roaming this portal.

also, people in here still assume when i try to make a joke on something ducky, that I just didn't understand something correctly and either treat me as if I signed up yesterday or ... well, that's it, actually. :D

@HaraldHanche-Olsen you can't trust politicians to get anything right

Joseph Wright

12:22 PM

@DavidCarlisle Done: it's a string test so relatively easy

Krishna

@JosephWright The robustify solution you posted here does not work

Joseph Wright

@Krishna Can you post a screenshot

Krishna

@JosephWright Sure, I could. This will just lengthen the question without adding meat to it. I This is a direct link to a public overleaf document which shows the code and the rendering. Is this okay? overleaf.com/19349431rysdtbdjwcxm#/72086837

@HaraldHanche-Olsen This island urgently needs a better internet connection, I'm missing the ooh counter!

@Krishna ^^^

Krishna

That's what I got.

samcarter

@marmot With multiply it was surprisingly easy. My first idea was to use complementary colours and then create the image two times, once with additive and once with subtractive colour mixing in the hope than upon combination the right bits would cancel each other out but luckily this was not necessary.

Krishna

And, what I want is not the same as your screenshot either. The desired thing is soomething else. The leading tablenotes should stay close to first digit, while the columns are still lined up at the decimal point

Joseph Wright

@Krishna table-align-text-pre = false does that

Krishna

@JosephWright Nope, still not working

Bernard thinks this is a bug with table-align-text-pre = false

In his words, "what's not working is table-align-text-pre=false (I tried it, but as it didn't work, I didn't use it in the code I posted). Maybe there's an interaction with the S column type."

12:37 PM

@Krishna Something may be up here, but you definitely have an old version causing issues too

Krishna

@JosephWright Well, I religiously update my TL distribution twice a day :)

Wait a minute, this is overleaf, which uses TL2017...... I am going to try the table-align false flag in my local computer

samcarter

@marmot Out of curiosity: in your coil ring, how do you make sure that the start and end will line up and nothing like this happens:

Krishna

Hooray! That actually worked. Thank you.

So, sometime between TL2017 release and today, this was fixed.

Overleaf currently uses TL2017

From their history for the last 3 releases, it looks like Overleaf seem to update their docker images to the latest TL only in November

Phelype Oleinik

Good Morning friends!

Quick question for expl3 experts: Does expl3 have some number formatting function?

Something like a \int_print_leading_zeros:nn { 1 }{ 3 } which prints 001...

12:53 PM

@PhelypeOleinik no, as far as I know

Phelype Oleinik

@boycott.se-yo' Ooh, I was really hoping otherwise U_U

boycott.se - yo'

@PhelypeOleinik but what you ask for is not that difficult to achieve

Phelype Oleinik

I guess that that something like ~~two@digits~~ \int_digits_two:nn will have to do it for now :P

boycott.se - yo'

@PhelypeOleinik why two parameters? And remember that you are not allowed to use the \int_ namespace. Get your own namespace

Phelype Oleinik

@boycott.se-yo' I did something comparing the value of the number, but I thought that there was something built-in.

@boycott.se-yo' I didn't name it that way. Just kidding ;)

boycott.se - yo'

1:01 PM

@PhelypeOleinik ok

Phelype Oleinik

@boycott.se-yo' Thanks :)

boycott.se - yo'

well, I would use something like \prg_repliacate:nn{\int_eval:n{5-\str_count:o{\int_to_arabic:n{#1}}}}{0}#1

where you have to \cs_generate_variant:Nn \str_count:n {o} and where I many errors on the way

@PhelypeOleinik ^^

@boycott.se-yo' Thanks a lot :D

boycott.se - yo'

@PhelypeOleinik this is not expandable, but you probably don't need that.

Phelype Oleinik

@boycott.se-yo' Not right now. I couldn't get it working by nesting the \int_eval:n in \prg_replicate:nn when I changed the signature of \str_count to :f

@boycott.se-yo' And I did change that because apparently the signature :o counts \int_to_arabic:n as a bunch of characters, then \int_eval:n would return something like -45

@JosephWright rebuilding oberdeik bundle (again) (takes about 45 minutes or so :(

@boycott.se-yo' Expandable now :)

@boycott.se-yo' I really don't know why it didn't work earlier :/

@samcarter spirograph when the pen slips out of the wheel :-)

@JosephWright voted:-)

marmot

@samcarter There is an easy part: make sure that there is no fractional coil. This has been solved by Jake in tex.stackexchange.com/a/25689/121799, that's why it's easy. The more tricky part is to make sure that all, i.e. also the first and last coil, are 3D-like, i.e. have a white boundary.

samcarter

2:17 PM

@marmot Oh, that is a pretty neat trick!

@DavidCarlisle Indeed, that is a very good description.

2

@marmot The marmot is waiting to jump through the coil ring :)

2

marmot

@samcarter Yes, I am working on it. ;-) But the problem is that the shifts are in tangent space. So I really do not know how to make it work for all possible amplitudes and segment lengths...

samcarter

2:32 PM

@marmot Maybe the trick is to just restrict the possible amplitudes and segments lengths to the ones that are working :)

marmot

@samcarter Well, the thing is that I am almost there.

I think it would be a nice thing to have if it worked. (I played with these things in tex.stackexchange.com/a/447546/121799 and there it seems to work. Really the only problem is to make sure that the last tiny bit is also 3D like, but this seems to be tougher than expected...)

@Krishna Ooh, tlmgr is a religion, now?

David Carlisle

@HaraldHanche-Olsen reserve such descriptions for emacs

@PhelypeOleinik oh yeah, I think two expansions are needed. Safest would be simply :x
