Clippy VS BQN

cargo, rustfmt, clippy, rust-analyzer, and Rust’s robust unit testing capabilities together form a powerful ecosystem for managing large-scale projects like Spin.

Firstly, I added a section to run the code formatter rustfmt and the linter clippy:

I couldn't find it in the API guidelines either. From what I understand, the idea is that any trait bounds, which includes generic type parameter bounds and lifetime bound on a type (struct or enum) would be repeated back in the impl block

there is a nice discussion on this issue here: https://github.com/rust-lang/rust-clippy/issues/1689

You should not blindly follow clippy lints. They are sometimes wrong. Another example https://github.com/rust-lang/rust-clippy/issues/9782 .

I often write () = f() to assert that f() is unit. Unfortunately clippy warns on such code ( https://github.com/rust-lang/rust-clippy/issues/9048 ). There are very recent pull requests for this bug, so hopefully this bug will be fixed very soon. But meanwhile I invented this workaround: [()] = [f()] :)

Apart from running clippy on many projects being essential, clippy is also an exceptionally welcoming project, no matter your prior knowledge.

clippy is a great place to get started :) though it isn't exactly new.

clippy is also pretty compiler-adjacent and unlike rust-analyzer uses rustc's internal APIs. Don't let the size of the code base scare you off! It's actually feasible for a newcomer to contribute even such a substantial change as a new lint, and we have issues labeled as "good first issue" that come with mentorship, so you don't need to go it alone.

Yes, you could use it to write a lint. Although you might find it easier to just fork Clippy and add your own lints to their existing framework.

BQN[1] (an APL variant). There is something really beautiful/elegant to me about composing higher order functions in a purely point free way. Array programming is a nice application of this, and this one has the best ergonomics.

I recommend checking BQN at https://mlochbaum.github.io/BQN/ and the YouTube channel code_report by Conor Hoekstra (and also "Composition Intuition by Conor Hoekstra | Lambda Days 2023"). It is well documented.

Uiua is an interesting new language. Strongly influenced by APL and BQN, it's array-oriented and stack-based. To explore it briefly, I will walk through my solutions to this week's Perl weekly challenge (242).

Forth and Lisps tend to be fairly visual syntax free as well.

I'm just speculating though, looking for someone with experience to confirm or rebuke.

APL (the first, invented in the 1960s): https://en.wikipedia.org/wiki/APL_(programming_language)

BQN (a modern APL, looks like an inspiration for Uiua though I don't know): https://mlochbaum.github.io/BQN/

Too many smaller esoteric languages to count.

There is no need to have a specific keyboard. The actual solution depends on what APL you're using, but the principle is the same. The various symbols are available on the regular keys, and you use some way to indicate that you want the APL symbol rather than the regular symbol.

Dyalog has two different IDE's the support this. Ride uses backquote by default, while the windows IDE uses control.

Kap uses backquote in all its interfaces. Here's what it looks like in the web version: https://kapdemo.dhsdevelopments.com/clientweb2/

Likewise, BQN does the same thing, but uses backslash: https://mlochbaum.github.io/BQN/

When using GNU APL there is an Emacs mode available (which I am the author of) that provides an input method.

So the long story short, you should be able to get going with any array language without getting any special keyboard.
