Okay, I can't keep the urge of making my own spreadsheet program at bay any longer.
Let's get started.
Tiny 58 bytes csv parser, now it's time to implement spreadsheet formulae.
Starting selection, gosh, I love doing gui apps in postfix programming languages.
Cells with computed values will have a different background.
Wrote a little spreadsheet evaluator in 4000 bytes of #uxn bytecode.
Started improving input, added a form at the bottom that let's me see the spreadsheet's formulae and edit them.
Aight, back to building a spreadsheet program in assembly. I will try to display border highlights around the region read in each of the formulae.
https://git.sr.ht/~rabbits/nebu/tree/main/item/src/nebu.tal
Implemented highlight for cells from which the formulae is pulling its values.
I'm finally building my dream spreadsheet application, and it's going to be a mere 5kb program that runs on all our old devices.
