H²O² is poisonous

[–] [email protected] 58 points 6 months ago (9 children)

Lemmy supports subscript! H~2~O~2~ displays as H~2~O~2~.

And on kbin it shows as strikethrough, so the 2s are crossed out.

Now all I want is inline TeX.

[–] [email protected] 13 points 6 months ago (1 children)

I do quite like how clear TeX is. The curly braces make it completely unambiguous how everything is supposed to be parsed, which means even though it's a little more awkward to write, it's still a lot easier to write if your comments are getting more complicated. Plus it's so much easier for the parsing libraries to get right.

I just love how universal it is. Sure, it has its flaws, but its strength is how many different applications use it. Once you know how to write TeX, you can express any equation you want clearly and understandably, as opposed to trying to write it with Unicode. Bonus points for how easy it is to add TeX rendering to the web with libraries like KaTeX (my personal favourite) or MathJax. I was able to add TeX support to my blog in 10 minutes.

I'm a bit of a sucker for TeX as might be apparent from my infodumping. If anyone's as passionate and doesn't know of it yet: You should try the https://texnique.xyz game. It's a timed TeX typing game. I can get up to 70-80 points in it fairly consistently :D

I just love how universal it is.

Lol!

Half of the stuff people expect to work is library code that isn't even bundled at the default TeX context. Most of the symbols don't even come packaged with the TeX interpreter.

Somebody should really make a "standard TeX" and LaTeX should adopt it.

[–] Opisek 4 points 6 months ago* (last edited 6 months ago)

Yes, universal. Many websites, apps, communicators etc. implement a flavour of TeX. They will differ in some more complex features or commands, but your $a^2+b^2=c^2$ will work. And that's the point. For most times, you'll just want to communicate some simple concepts.

We could do better, for sure. For example, there's been some development around Typst, which tries to resolve many of those quirks, annoyances, and inconsistencies that come with TeX. It makes sense, since TeX evolved rather naturally and outgrew what it was initially comprised to be. While I'd love to see Typst come far, for now TeX is something that I take for granted, which perhaps better encompasses my thoughts than the word "universal".

Your example doesn't work for me but the one above is shown in superscript

[–] [email protected] 3 points 6 months ago (2 children)

Oh that's quite weird. What client is that?

[–] teejay 9 points 6 months ago

Sync

[–] [email protected] 5 points 6 months ago

It does not work in Boost as well

[–] jaybone 2 points 6 months ago

Shows as superscript on Memmy.

[–] T4V0 11 points 6 months ago

Works on Voyager at least.

[–] [email protected] 11 points 6 months ago* (last edited 6 months ago) (3 children)

H~2 O~2

Something new to bring to the Sync developer's attention.

[–] [email protected] 7 points 6 months ago

Hey @[email protected] this formatting doesn't seem to work in Sync :)

[–] [email protected] 2 points 6 months ago

You need to surround the text. H~2~O~2~ = H~2~O~2~.

[–] qaz 4 points 6 months ago (1 children)

Your example is also rendered

[–] [email protected] 11 points 6 months ago (1 children)

Huh? I know some clients fail to properly display superscript and subscript (which shouldn't be a problem since it would be the same for my text as for the above text anyway), but I didn't think there were any clients that would choose to render code snippets as formatted text. Anyway, here's a screenshot of how it should look:

[–] qaz 4 points 6 months ago (1 children)

Thanks, it seems to be a bug with the Thunder app.

[–] [email protected] 3 points 6 months ago

Also Infinity

[–] [email protected] 3 points 6 months ago

Worked in Voyager iOS at least, very cool

[–] [email protected] 22 points 6 months ago

Hydrogen peroxide, right?
