Re: [racket-users] Announcing something Kinda FRP-y
I did not even think to extend it that way! What a cool suggestion. Right now I am working on a macro as defined here, since there are times it makes sense to list dependencies explicitly https://github.com/zyrolasting/kinda-ferpy/issues/2 Now if I could get a #-notation to support explicit dependencies without sacrificing too much readability, I'd probably prefer it over all other variants.

Re: [racket-users] Announcing something Kinda FRP-y
Hi Sage, This is pretty cool. With a non-OOP option on the table, I might finally get around to working on an IMGUI-like for Racket. Have you thought about a reader extension to compress the notation? The `stateful-cell` function kinda acts like a box and kinda looks like a `syntax` (or `quote-syntax` w/ kw arg) form, both of which have special #-prefixed notations. Extending the reader to abbreviate `(stateful-cell 1)` and `(stateful-cell (λ _ (+ (x) (y` to, say, #?1 and #?(+ (x) (y)), respectively, could be a fun project.

[racket-users] Announcing something Kinda FRP-y
Announcing a new package: kinda-ferpy. Here's a [write-up](https://sagegerard.com/kinda-ferpy-intro.html). It implements the spreadsheet metaphor in an expressive way, based on MaiaVictor's excellent [PureState library](https://github.com/MaiaVictor/PureState). It's not a complete functional reactive programming interface, but it does conveniently express Racket values as dependent computations. (require kinda-ferpy) (define x (stateful-cell 1)) (define y (stateful-cell 1)) (define sum (stateful-cell (λ _ (+ (x) (y) (displayln (sum)) ; 2 (y 8) (displayln (sum)) ; 9 ~slg -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
