Folks building with IronCalc!
I made a spreadsheet app in #rust with #ratatui and #ironcalc. It was way easier than I thought it would be. The apis of both of those crates were really easy to work with. * ratatui: docs.rs/ratatui/0.29... * ironcalc: docs.rs/crate/ironca... * The code: dev.zaphar.net/zaphar/sheetui
We used the fantastic regex-lite crate from @burntsushi.net and reduced the wasm build in 1 Mb! The total js+wasm+other downloaded in the IronCalc app is 583kB. Long live lean software!
