Keep getting sidetracked by making little Lua libraries. This one implements Python-style f-strings in Lua. Pretty cool to have a language that lets you go this far with its syntax. With just a little bit of work this could be extended to implement Python's template strings (PEP 750) and then we could use Lua to make all sorts of DSLs. My initial motivation was easier printf debugging, though 😅. I started working on this on an iPad with the Codea app, of all things. Was fun, but sadly I couldn't use any of the Bret Victor-inspired things they had in it since I wasn't using any of the app-specific libraries they had. Though putting aside the library, I think at this point the most interesting thing I did is actually making it possible to use it right on my website without having to install or download anything. https://ezhik.jp/f-string.lua/

So cute.
