Detailed Description

A formatter for Bond parse trees.

PrettyPrinter converts parse trees back into Bond source code using consistent formatting rules. It can optionally emit minimal formatting and fold constant expressions.

Member Enumeration Documentation

◆ ConstantFolding

enum Bond::PrettyPrinter::ConstantFolding

Controls whether constant expressions are folded before printing.

Enumerator
CONSTANT_FOLDING_OFF	Print expressions without constant folding.
CONSTANT_FOLDING_ON	Fold constant expressions and print their literal values.

◆ Verbosity

enum Bond::PrettyPrinter::Verbosity

Controls whitespace and layout verbosity in pretty-printed output.

Enumerator
VERBOSITY_NORMAL	Full formatting with standard whitespace and line breaks.
VERBOSITY_MINIMAL	Compact formatting with minimal whitespace.

Member Function Documentation

◆ Print()

void Bond::PrettyPrinter::Print	(	const ParseNode *	parseNode,
		OutputStream &	stream,
		Verbosity	verbosity = VERBOSITY_NORMAL,
		ConstantFolding	folding = CONSTANT_FOLDING_OFF ) const

Prints Bond source code for a parse tree rooted at a single parse node.

Parameters

parseNode	Root parse node to print.
stream	Output stream receiving the formatted Bond source.
verbosity	Controls output spacing and compactness.
folding	Controls whether constant expressions are folded before printing.

◆ PrintList()

void Bond::PrettyPrinter::PrintList	(	const ListParseNode *	listNode,
		OutputStream &	stream,
		Verbosity	verbosity = VERBOSITY_NORMAL,
		ConstantFolding	folding = CONSTANT_FOLDING_OFF ) const

Prints Bond source code for a parse tree represented as a list of parse nodes.
