Magellan: A dumb, deterministic codebase mapping tool

Magellan observes files, extracts symbols and references, and persists facts to sqlitegraph.

§Position Conventions

Magellan uses tree-sitter position conventions for all symbol and reference data:

  • Line positions: 1-indexed (line 1 is the first line)
  • Column positions: 0-indexed (column 0 is the first character)
  • Byte offsets: 0-indexed from file start

See MANUAL.md for detailed documentation.

§Feature Flags

§Backend Selection (Choose One)

Magellan supports two storage backends via sqlitegraph:

§SQLite Backend (Default)

  • sqlite-backend: Stable SQLite-based storage
    • Widely compatible, well-tested
    • Use for maximum compatibility

§Optional Features

  • llvm-cfg: LLVM IR-based CFG extraction for C/C++ (requires clang)
  • bytecode-cfg: Java bytecode-based CFG extraction (requires Java bytecode library)
