zener-language

Base language is normal Starlark — expressions, functions, loops, comprehensions, dicts, lists, load() . Below is the Zener-specific layer. Modules: Nets and interfaces: Components and sourcing: io() : config() : Utilities: Tool-managed metadata: Imports and dependencies: pcb.toml per package type: Prelude symbols available in .zen files without load() : Net , Power , Ground , NotConnected , Board , Layout , Part . Local definitions can shadow them. @stdlib/interfaces.zen : @stdlib/units.zen : Physical types: Voltage , Current , Resistance , Capacitance , Inductance , Impedance , Frequency , Temperature , Time , Power . Constructors accept point values and ranges: Arithmetic tracks units automatically: Voltage("3.3V") * Current("0.5A") → 1.65W ; Voltage("5V") / Current("100mA") → 50Ω . Properties: .value (alias for .nominal ), .nominal , .min , .max , .tolerance , .unit . Methods: .with_tolerance(t) , .with_value(v) , .with_unit(u) , .abs() , .diff(other) , .within(other) , .matches(other) .
