SCL

Structured Configuration Language: a typed, explicit configuration format with a stable C ABI library.

What it looks like

@scl 1

host: string = "localhost"
port: int @range(1, 65535) = 8080
debug: bool = false
tags: [string] = ["production", "v2"]

db: struct {
    url: string
    pool: int
} = {
    url = "postgres://localhost/app"
    pool = 10
}

Design

• Every field has an explicit type
• Invalid input is always a parse error, never a silent guess
• One syntax, one parse result
• Zero runtime dependencies in the core library

APIs

• Python

Docs

• Language reference
• C ABI reference

Building

Requires a C11+ compiler, a C++17+ compiler, and CMake 3.16+.
