quarb-code

The code level for the Quarb query engine — cross-language code navigation where function names are node names, not properties: /lexer/lex/is_name_char descends module, function, nested function — a filepath into the program — where the syntax level spells the same question //function_item[::name = "lex"].

A declaration's edge name is its declared identifier; the remaining constructs keep a small normalized vocabulary (if, switch, for, call, …); everything else dissolves. Curated traits (<function>, <type>, <loop>, …) classify across languages, ::signature / ::doc / ::callee are uniform properties, ->definition crosslinks resolve calls to their same-file declarations, and the raw grammar kind survives only as ::::kind. Built on the quarb-tree-sitter parse (the syntax level, which remains the default reading of source files; the code: target prefix opts up). Grammars: Rust, Python, JavaScript, C.

History note: through 0.21.0 this crate name hosted the tree-sitter syntax-level adapter, now published as quarb-tree-sitter. From 0.22.0, quarb-code is the code level.

Part of Quarb, a query language for arbors — tree-spanned graphs (a hierarchical backbone enriched with non-hierarchical "crosslink" relations). This crate is an adapter: it maps its data source onto the arbor model so the shared quarb engine can query it, and the qua CLI can reach it alongside every other source.

See quarb.org for the language specification, the user guide, and the full list of adapters.
