Classes
struct	donner::editor::sandbox::DiffResult
	Result of comparing two .rnr recordings. More...

Namespaces
namespace	donner
	Top-level Donner namespace, which is split into different sub-namespaces such as donner::svg and donner::css.

Functions
DiffResult	donner::editor::sandbox::ComputeRnrDiff (const RnrHeader &headerA, const std::vector< DecodedCommand > &cmdsA, const RnrHeader &headerB, const std::vector< DecodedCommand > &cmdsB)
	Compares two decoded .rnr recordings and produces a unified-diff-style report. Header fields are compared first, then the command streams are aligned with a plain O(N*M) longest-common-subsequence and emitted with +/-/ prefixes (indented by each command's depth).

Detailed Description

Structural diff engine for .rnr recordings. Compares two decoded command streams (and their headers) using a longest-common-subsequence alignment, producing a unified-diff-style report suitable for regression triage.

Function Documentation

ComputeRnrDiff()

DiffResult donner::editor::sandbox::ComputeRnrDiff	(	const RnrHeader &	headerA,
		const std::vector< DecodedCommand > &	cmdsA,
		const RnrHeader &	headerB,
		const std::vector< DecodedCommand > &	cmdsB )

Compares two decoded .rnr recordings and produces a unified-diff-style report. Header fields are compared first, then the command streams are aligned with a plain O(N*M) longest-common-subsequence and emitted with +/-/ prefixes (indented by each command's depth).

Parameters

headerA	Header from the first recording.
cmdsA	Decoded commands from the first recording.
headerB	Header from the second recording.
cmdsB	Decoded commands from the second recording.
