This post describes a library design for resilient recursive parsing that enables parsers to recover from errors and continue parsing, useful for IDE features like auto-completion. The approach extends combinator libraries like nom with greedy error recovery that skips forward to resume parsing, while maintaining minimal runtime overhead during error-free parsing and requiring modest changes to parser logic.
This section explains Batcher's Bitonic Merger Sort, a circuit design using butterfly networks to recursively merge sorted sublists. The approach defines circuit combinators like riffle, unriffle, ilv, and evens to build efficient sorter networks that handle bitonic sequences where the first half increases and the second half decreases.
