You're looking for something that's readable but more efficient and smaller than #json or #yaml?
Structure data with #ascii control codes like people did in 1963!

@astro oh, are you going to FOSDEM? 👀
If so, I'm very jealous. Also send @straightshoota best wishes if you see him and maybe you can have a look as his talk to if you're a little curious about @CrystalLanguage . 😉

Continuing my work on a Inertia.js adapter for #CrystalLanguage and wondering what should I do for example application? I think porting PingCRM to Crystal is too much😅
Currently working on a Inertia.js server-side implementation for #CrystalLanguage with no framework dependencies. Lot of rough edges and features to implement, but looks promising! 😊
