I’ve been dipping my toes into the world of this last week, giving a shot (because you know, ).

My goal is to recreate Pac-Man, which has proved to be trickier than excepted.

Making games is hard (at least so far), but it’s been a fun to think about code in a way I haven’t before.

janriemer,

@jgayfer This sounds awesome!

Bevy is probably the most flexible and modular system I've ever come across. It is so well designed! ✨

If someone asked me: "How to build modular software?", I'd refer them to Bevy.

It was how I learned about ECS for the first time. The ECS pattern is mind-blowing to me and such a natural fit for Rust! 🤯

Have fun on your Bevy journey! :awesome: Don't be discouraged, if something doesn't go right the first time. This is how we learn (I'm Bevy newbie, too). 🙂

Sometimes, when programming in , I'm wondering whether there is a little Ferris in my computer whispering to all those 0's and 1's to behave correctly. :ferris:

Otherwise I can't describe the following experience:

  1. Rewrite parts of a programming language from to (the parts that are most interleaved with each other => indirect recursion over multiple non-terminals!).
  2. Run all affected tests
  3. See all of them pass on the first try!

janriemer,

I was wondering:

  • Have I really saved my files? Yup! ✅
  • Have I really used the new chumsky impl in the tests? Yup! ✅
  • Am I dreaming? 💭 Nope!

Companies, if you need reasons to adopt Rust: this is why you should! 👆 🦀

Having said that: after the refactor, I'm getting exponential parsing time in some scenarios (again! I've had them with nom as well. 😪 ). There is still some left recursion in my grammar, so that's probably why and I had to change one spot where parsing differs.

2/2

janriemer,

Nice, I've solved the exponential parsing times! 🚀

The solution was to not call the parser returning functions directly, but instead pass in callbacks (by using recurse - chumsky doesn't support this natively, I've patched it).

How did I come up with the solution? I don't know... ¯_(ツ)_/¯ Seriously, call it intuition.✨

Some people: "Rust's syntax is so confusing to me." 🥴

The project: "Let's match that confusion with even more confusing syntax!" :awesome:

🤦

janriemer,

Seems like there has already been a bug in the compiler for postfix match 4 days ago.🙄

https://github.com/rust-lang/rust/issues/123064

This is the consequence of adding new features!

Fortunately, it has been fixed very quickly (1 day later!). Kudos to the Rust maintainers for reacting so quickly!

janriemer,

Frequently requested changes | Fundamental changes to 's syntax

https://lang-team.rust-lang.org/frequently-requested-changes.html#fundamental-changes-to-rust-syntax

"[...]These also include proposals to add "alternative" syntaxes, in addition to those that replace the existing syntax."

"[...]The established Rust community with knowledge of existing Rust has a great deal of value, and to be considered, a syntax change proposal would have to be not just better, but so wildly better as to overcome the massive downside of switching."

janriemer,

@mo8it

Yes, but it shows that adding features has a cost, so it should better add substantial value to the language.

"Perfection is reached, not if there is nothing more to add...but when there is nothing more to remove."
