It took me way too long to notice the horror on the right

Wow, so this is possible.
Formatting is so damn arbitrary. Somebody has to have tried storing just the parse tree on disk, right?
If you do that, you lose formatting and comments every time you load the source from disk
Losing formatting other than what you've set in your deparser would be the point. Losing comments would be bad, but that seems easily fixable just by giving each comment block a symbol that points to it's contents.
Or by including comments in the parse tree. (& Yes, it is done various places for various languages and formats.)
Do you have some examples?
(That is what I meant by giving them a symbol, maybe I worded it poorly)
The best example I have is a closed source one and I can't be more specific on what it is than to say that it's probably installed on at least one of your Apple devices (assuming you have any).
Implementation-wise, the syntax tree nodes have additional attributes that hold pre- and/or post-element text. What's on disk is the serialized tree. You edit a text version, and it's parsed on every edit so it doesn't have to be parsed again at evaluation time, and what's stored is the parse tree with enough whitespace and comment hints to reconstruct the text for editing.
This is a case where looking at the textual code is rare, but hundreds of results must get updated in realtime on every change. This might be enough of a hint as to what program it is.
I like python like really really like it. But this should be a warcrime
No
Hang on, this is just a C++ joke slapped onto Rust.
You could say they have rewritten the joke in Rust
But you get the joke faster now.
No, it's just impossible for it to leak out of a hole in the back of your head that you didn't realise was growing under your pony tail.
A funny, but incredibly subtle joke to do would be to do a post like this, but get the indentation subtly wrong somewhere, so something that's supposed to be inside a loop is outside according to indentation, but is inside according to braces.
To me it just looks like you do not need the braces at all
I'm good at Python, and I don't know Rust. This looks fine to me. I've fully missed the joke.
Same. Until you notice the column of curly braces and semi colons in the right margin.
Oh... Oh god
Lgtm ship it to prod
Lgtm? Let's go to Madrid?
You never review code when you have no time to do an actual review? Looks good to me :)

Oh, so Rust is like JavaScript!
No, Rust lacks the semicolon elision rules of Javascript which make everyone always use semicolons in javascript because they're so horribly broken.
Rust is like ML, quite literally, not just by ancestry: The syntax is palpably ugly, but at least it's sane, regular, and concise where it matters.
Pretty sure javascript is like c but I I can't be mad at the js devs for the awful language they write.

rustfmt
is stopping me from writing code like this, and I have never been more happier using it after viewing this.
I'm going to write a tool that automatically adds the braces and semicolons to the column as you edit the code.
I will call it rustfml
Please do, I'm waiting for it to get ported to other languages.
Crap, thats what I was thinking.
Then some jerk runs rustfmt and ruins all your hard work!
Can't you fix the default format to this?
My medication mostly.
I hate it with every fibre of my being but also secretly calmed by that column of statement terminators and brackets.
It's like the code representation of the Vancouver riots kiss photo.
Why would that cause the same feeling?
I'm not sure if you're taking the piss or not but I'm going to choose to believe you're asking in good faith!
The code just feels... messy, unfamiliar, almost chaotic - but the semicolons and curly brackets in a neat little row, formatted in a satisfying way, is like an island of calm and order in the middle of a formatting clusterfuck.
A moment of serenity in the middle of a riot, one may think.
Ohhhh thanks for the explanation, I'm a bit stupid :3
Also, I didn't mean it in a bad way, a genuine question. Thanks for assuming it's in good faith ^^
This makes my deeply uncomfortable, like an itch I can't quite scratch.

DwangoAC and the TASBot crew are maniacs in the best possible way. I would like to continue having a high opinion of him, hence I will pretend that this post does not exist.
My eyes! My eyes!!!!

Oh... Oh! Well, that is creative.
I’ll allow it!
