ast-outline 2.1.1

ast-outline (final release — 2.1.1)

This project has been renamed to ast-bro

ast-outline started as a shape extractor. It grew into a multi-subsystem toolkit covering dep & call graphs, hybrid semantic search, and AST-aware structural rewrite. "Outline" no longer fit, and the name collided with an unrelated VS Code extension and an npm package. The project lives at github.com/aeroxy/ast-bro going forward.

This 2.1.1 release is the final version under the ast-outline name. It ships the same code as ast-bro 2.2.0, and bundles the new ast-bro and sb binaries alongside ast-outline so existing users can start using the new names before switching packages. Every ast-outline --help invocation prints the discontinuation notice with the upgrade path.

Switching to ast-bro

Pick the installer for your ecosystem:

brew install aeroxy/tap/ast-bro
npm install -g @ast-bro/cli
pip install ast-bro
cargo install ast-bro

After install, run ast-bro --help, sb --help, or any of the subcommands documented in the ast-bro README. All scripts you have today that call ast-outline will keep working as long as the ast-outline package or formula stays installed; once you uninstall it, your ast-outline shim disappears and your scripts should call ast-bro (or sb) instead.

What this 2.1.1 release ships

Every install method (crate, brew, npm, pip) installs three commands. They're the same binary:

  • ast-outline — the original CLI (still works, no further updates)
  • ast-bro — the new canonical name
  • sb — a shorter alias

Capabilities (unchanged from ast-bro 2.2.0):

  • File shape — map / digest / show / implements — signatures with line ranges instead of method bodies; AST-accurate subclass lookup.
  • True public API — surface resolves re-export graphs across Rust, Python, TypeScript, Scala.
  • Dependency graph — deps / reverse-deps / cycles / graph — file-level imports for nine languages.
  • Call graph — callers / callees — AST-accurate, with confidence tags from a three-pass resolver.
  • Hybrid semantic search — search / find-related — BM25 + dense embeddings via potion-code-16M.
  • Structural rewrite — run -p '<pattern>' -r '<replacement>' — AST-aware find/replace with metavariables.
  • MCP server — mcp — every subcommand exposed as an MCP tool.

Supported languages: Rust, Python, TypeScript, JavaScript, Java, C#, C++, Kotlin, Scala, Go, PHP, Ruby, SQL, Markdown.
