yaml-cpp is a C++ library for parsing and emitting YAML 1.2 documents. It provides a complete YAML processing pipeline, from reading YAML content into a traversable node tree to writing in-memory data structures back as YAML text. The library represents parsed YAML as a mutable tree of typed nodes, supporting scalars, sequences, maps, and aliases. It uses a recursive-descent parser to build this node tree, and a stream-based emitter to generate YAML output incrementally. Template-based type conversion enables compile-time serialization between YAML nodes and C++ types, including support for c
Queries whether a node is a scalar, sequence, map, null, or undefined to handle heterogeneous data safely.
HexFiend is a native macOS hex editor designed for opening and editing binary files of any size without loading them entirely into memory. It uses a 64-bit addressable data model with memory-mapped file access, enabling navigation of multi-gigabyte files while maintaining byte-level undo for insert and delete operations. The editor distinguishes itself through a diff algorithm for binary file comparison that accounts for insertions and deletions, and a template-based structure parsing system that uses user-defined scripts to visualize binary file layouts. It also includes a typed data interpr
Interprets raw bytes as integers, floats, or other types with configurable endianness and signedness.
