Oho you are also building a DSL for full stack web apps, I didn't expect that :D! Consider joining our Discord (
https://discord.com/invite/rzdnErX), I would love to learn more about your quack!
True, right now it is just one file, and language is a simple "configuration", declarative language, just because we didn't need more so far. This is how we started, because we wanted to focus on capturing the basic abstractions of the web app at high level, and we want to keep the language as simple as possible -> so we decided to start really simple and then extend as we need more power.
We will certainly add splitting into multiple files, and will probably go beyond that with actual modules, expressions, simple conditional logic, basic types and similar - kind of like meson (https://mesonbuild.com/Syntax.html) and Terraform.
Right now we don't see it ever becoming a Turing complete language, since we don't intend to capture the low-level logic in Wasp - we feel existing solutions are better fit for that (JS/TS/HTML/CSS/...) and we would not be doing our best work there, nor would we be able to keep up with the innovation.
Although, never say never -> my mind does wander off to Mint (https://www.mint-lang.com/) every so and so, thinking if we could do something similar at some point -> but even if we do, that is further down the road.
