Module dsl 

DSL parser for .pedal circuit definition files.

Parses component declarations, net connections, and control mappings into an AST that can drive WDF tree construction or KiCad export.

Structs

CapConfig

Extended capacitor configuration with parasitic modeling.

ComponentDef

A single component declaration, e.g. R1: resistor(4.7k)

ControlDef

Control mapping: Gain.position -> "Drive" [0.0, 1.0] = 0.5

InitHint

One device hint from the init { ... } block.

MonitorDef

Monitor definition for real-time metering visualization.

NamedSupply

A named power supply rail.

NetDef

A net connection: in -> C1.a or C1.b -> R1.a, D1.a

PedalDef

Top-level pedal definition.

PortDef

Named port declaration from the .pedal DSL.

SidechainInfo

Sidechain definition for feedback compression loops.

SubcircuitDef

A subcircuit block within a pedal/equipment definition. Subcircuits partition a circuit into named sub-networks that can have independent rate domains (e.g., audio path vs. sidechain).

SupplyConfig

Power supply configuration — models B+ rail behavior under load.

TapeHeadConfig

Voltage-driven Jiles-Atherton tape head configuration.

TransformerConfig

Audio transformer configuration.

UseInstance

A file-based subcircuit instance: micamp: use("../sub/ba284.pedal").

Enums

AnalogSwitchType

Analog switch IC types.

BbdType

BBD (Bucket-Brigade Device) types for analog delay lines.

CapType

Capacitor dielectric types with different parasitic characteristics.

ComparatorType

Comparator IC types.

DiodeType

InitState

Named or explicit initial state for one NL device in an init { ... } block.

LfoWaveformDsl

LFO waveform shapes for DSL.

MatchedTransistorType

Matched transistor pair/array types for exponential converters.

MeterType

Meter type for monitor visualization.

MosfetType

MOSFET types for enhancement-mode devices used in guitar pedals.

NeonType

Neon bulb types for relaxation oscillators and optocouplers. Neon bulbs exhibit negative resistance behavior:

OpAmpType

Op-amp types with different characteristics. Each type has distinct slew rate, gain-bandwidth product, and input impedance that affect the tone and response of the circuit.

PhotocouplerType

Pin

A pin reference – either a reserved node (in, out, gnd, vcc), a component pin (C1.a, R1.b), or a fork for dynamic routing.

PotTaper

Potentiometer taper type.

RectifierType

Rectifier type — determines supply output impedance character.

SidechainTarget

Sidechain target — what the sidechain CV modulates.

SpringTankType

Spring-reverb tank models (Accutronics / RE-201 grounded).

VcaType

VCA (Voltage-Controlled Amplifier) IC types.

VcfType

VCF (Voltage-Controlled Filter) IC types.

VcoType

VCO (Voltage-Controlled Oscillator) IC types.

VcoWaveformDsl

VCO waveform selection for DSL.

WindingType

Transformer winding configuration.

Constants

DEFAULT_NPN_MODEL

Default SPICE model name for a generic NPN BJT.

DEFAULT_PNP_MODEL

Default SPICE model name for a generic PNP BJT.

Functions

parse_pedal

Parse a complete .pedal or .synth file. Both pedal "Name" { ... } and synth "Name" { ... } produce the same AST.

parse_pedal_file

Convenience wrapper that returns Result.
