Snapdragon Utilities

snapdragon-util provides a focused collection of utility functions designed to interact with the Abstract Syntax Tree (AST) nodes generated or consumed by the `snapdragon` parser/compiler ecosystem. Key functionalities include robust node type checking (`isNode`), efficient value extraction from nodes (`value`), and critical compiler middleware helpers such as `noop` (for ignoring nodes), `identity` (for direct value appending), `append` (for custom value appending), and `toNoop` (for transforming nodes into empty text nodes without re-indexing). The package is currently at version `5.0.1` and is part of a stable, actively maintained ecosystem primarily targeting Node.js environments. Its core differentiation lies in its tight integration with `snapdragon-node` instances, making it indispensable for extending or customizing `snapdragon`-based parsers and compilers.
