pulp::format::rack Namespace Reference

Namespaces
namespace	volts
	Published modular voltage standards. Centralized so no module can drift.

Classes
struct	ParamSpec
struct	PortSpec
struct	LightSpec
struct	ModuleDescriptor
	One module: everything needed to emit its panel, its manifest entry, and its widget placement. More...
struct	PluginManifest
	A whole plugin: brand plus its modules. More...

Enumerations
enum class	ControlKind {   KnobLarge , Knob , KnobSmall , Trimpot ,   Toggle , Button }
	Which physical control renders a parameter. More...
enum class	PortRole {   Audio , Cv , Pitch , Gate ,   Trigger , Clock }
	What a jack carries. More...

Functions
constexpr double	hp_to_mm (int hp)
constexpr double	mm_to_px (double mm)
constexpr double	control_radius_mm (ControlKind k)
	Drawn footprint radius in mm for each control kind — the radius of what Rack actually paints, not of the authoring placeholder.
const char *	widget_class (ControlKind k)
	The Rack widget class this control maps to.

Variables
constexpr double	kHpMm = 5.08
	Eurorack geometry.
constexpr double	kPanelHeightMm = 380.0 / 75.0 * 25.4
constexpr double	kRackDpi = 75.0
constexpr double	kJackRadiusMm = 4.11

Enumeration Type Documentation

ControlKind

enum class pulp::format::rack::ControlKind

strong

Which physical control renders a parameter.

Determines both the panel footprint and the Rack widget class, so the two cannot disagree.

Enumerator
KnobLarge	54 px / 18.29 mm — the hero control
Knob	36 px / 12.19 mm — standard
KnobSmall	25.5 px / 8.64 mm
Trimpot	17 px / 5.76 mm — attenuverters and secondary amounts
Toggle	10 × 20.6 px switch
Button	momentary

PortRole

enum class pulp::format::rack::PortRole

strong

What a jack carries.

Drives the label, the tooltip, and the panel's input/output treatment — outputs sit on a filled shape, inputs on bare plate, so the distinction survives greyscale and a dark room.

Enumerator
Audio	±5 V
Cv	0..10 V or ±5 V
Pitch	1 V/oct
Gate	10 V while active
Trigger	10 V, ~1 ms
Clock	trigger used as a time base

Function Documentation

control_radius_mm()

double pulp::format::rack::control_radius_mm ( ControlKind k )

inlineconstexpr

Drawn footprint radius in mm for each control kind — the radius of what Rack actually paints, not of the authoring placeholder.

Label clearance is computed from this, which is the check an SVG-only validator cannot make.

hp_to_mm()

double pulp::format::rack::hp_to_mm ( int hp )

inlineconstexpr

mm_to_px()

double pulp::format::rack::mm_to_px ( double mm )

inlineconstexpr

widget_class()

const char * pulp::format::rack::widget_class ( ControlKind k )

inline

The Rack widget class this control maps to.

Kept as a string because it is emitted into generated C++ and named in the panel manifest; the mapping is data, not a switch buried in the code generator.

Variable Documentation

kHpMm

double pulp::format::rack::kHpMm = 5.08

inlineconstexpr

Eurorack geometry.

1 HP is 5.08 mm; a 3U panel is 380 px at Rack's 75 dpi, which is 128.6933 mm — NOT the 128.5 mm quoted in the VCV manual. Authoring at 128.5 mm renders a panel one pixel short.

kJackRadiusMm

double pulp::format::rack::kJackRadiusMm = 4.11

inlineconstexpr

Jack footprint (PJ301M is 24.3 px square).

kLightRadiusMm

double pulp::format::rack::kLightRadiusMm = 1.39

inlineconstexpr

Medium LED (3 mm).

kPanelHeightMm

double pulp::format::rack::kPanelHeightMm = 380.0 / 75.0 * 25.4

inlineconstexpr

kRackDpi

double pulp::format::rack::kRackDpi = 75.0

inlineconstexpr
