Project structure

Directory	Description
pkl/	Pkl configuration sources
Sources/Gen/	Generated Swift sources from Pkl
Sources/App/	Swift files

Codegen

Generated sources are already checked into git for learning purposes.

To generate new Pkl sources, first install the Swift code generator:

curl https://github.com/apple/pkl-swift/releases/download/0.2.0/pkl-gen-swift-macos.bin -o pkl-gen-swift
chmod +x pkl-gen-swift

With that installed, generate Swift sources via:

pkl-gen-swift pkl/**.pkl -o Sources/Gen

Running the server

To run the project call swift run.
