evaluate() [1/2]

float pulp::view::RelativeExpression::evaluate	(	const Rect &	parent,
		const std::map< std::string, Rect > &	named = {} ) const

Evaluate this expression against the given parent rectangle and optional environment of named rectangles.

Throws std::runtime_error if a qualified name refers to a missing rectangle.

evaluate() [2/2]

float pulp::view::RelativeExpression::evaluate ( const std::string & source, const Rect & parent, const std::map< std::string, Rect > & named = {} )

static

Convenience: parse + evaluate in one shot. Throws on parse error.

parse()

RelativeExpression pulp::view::RelativeExpression::parse ( const std::string & source )

static

Parse a single-axis expression (e.g.

"right - 10"). Throws std::invalid_argument on syntax error with a position-bearing message.

to_string()

std::string pulp::view::RelativeExpression::to_string

(

)

const

Round-trip text form for diagnostics.

Re-parses to the same tree (numbers may be reformatted).
