hypergumbo 2.5.1

Local-first repo behavior map generator

hypergumbo

hypergumbo is a local-first CLI that generates behavior maps and sketches from source code. The goal of this project is to efficiently help developers and LLMs understand a codebase.

pip install hypergumbo

Requires Python 3.10+. For optional extras (embeddings, gitleaks, grammars), run hypergumbo add-extras after installing.

Intel Mac users: Some tree-sitter packages lack x86_64 wheels. See docs/INTEL_MAC.md for a Docker-based workaround.

git clone https://codeberg.org/iterabloom/hypergumbo
hypergumbo hypergumbo/

Output:

## Configuration
[...]

See full example output

Use -t to control the token budget:

hypergumbo . -t 1000   # brief overview (structure only)
hypergumbo . -t 4000   # good balance for most LLMs
hypergumbo . -t 8000   # detailed with many symbols

Two Outputs

Sketch (hypergumbo .) — Token-budgeted Markdown sized for LLM context windows. Ranks symbols by graph centrality (★ = most connected).

Behavior map (hypergumbo run) — Full JSON with all symbols, edges, and provenance tracking. Use this for programmatic analysis.

CLI Commands

hypergumbo [path]              # Markdown sketch (default)
hypergumbo run [path]          # Full JSON behavior map
hypergumbo slice --entry X     # Subgraph from entry point
hypergumbo routes [path]       # List HTTP routes
hypergumbo search <query>      # Search symbols
hypergumbo symbols [path]      # Browse symbols with connectivity
hypergumbo explain <symbol>    # Detailed symbol info
hypergumbo test-coverage       # Analyze test coverage (transitive)
hypergumbo catalog             # List analysis passes

Useful flags:

hypergumbo . -x                # exclude test files (faster)
hypergumbo . --with-source     # append full source code
hypergumbo . --no-progress     # hide progress indicator (on by default)
hypergumbo --help --all        # comprehensive help for all commands

Results are automatically cached in ~/.cache/hypergumbo/. Just run:

hypergumbo .    # auto-runs analysis if no cache exists, then generates sketch

The cache auto-invalidates when source files change. See docs/CACHE.md for details.

See hypergumbo --help for all options.

What It Understands

• Language analyzers: Python, JS/TS, Java, Rust, Go, C/C++, and many more
• Cross-language linkers: JNI, HTTP, WebSocket, gRPC, GraphQL, message queues (full list)
• Framework patterns: FastAPI, Django, Rails, Spring Boot, Phoenix, Express, and many more

How It Works

1. Profile: Scan the repo for languages, file counts, LOC
2. Analyze: Run language-specific analyzers to extract symbols and edges
3. Link: Connect symbols across language boundaries (JS fetch → Python route)
4. Enrich: Detect frameworks via YAML pattern matching
5. Output: Generate Markdown sketch or JSON behavior map

The Internal Representation

All analyzers produce the same IR types:

• Symbol: A code element (function, class, method) with name, location, and stable ID
• Edge: A relationship between symbols (calls, imports, extends, implements)
• Span: Source location (file, line, column)

This uniform IR is what allows all language analyzers and cross-language linkers to work together coherently.

├── hypergumbo-lang-common/      # Haskell, Elixir, GraphQL, etc.
├── hypergumbo-lang-extended1/   # Zig, Solidity, Agda, etc.

└── hypergumbo/                  # Meta-package (installs all above)

Key design choices:

• Registry pattern: Analyzers and linkers self-register via decorators
• Two-pass analysis: First collect symbols, then resolve edges (enables cross-file references)
• Provenance tracking: Every edge records which analyzer/linker created it
• YAML-driven patterns: Framework detection is declarative, not hardcoded

Development

git clone https://codeberg.org/iterabloom/hypergumbo.git
cd hypergumbo
python3 -m venv .venv && source .venv/bin/activate
./scripts/dev-install
source .venv/bin/activate  # reload to enable pytest alias
pytest                      # runs smart-test (affected tests only)

dev-install installs all packages, git hooks, and the pytest/smart-test wrapper. 100% test coverage required.

See CONTRIBUTING.md for PR workflow (including fork-based workflow for external contributors), smart test selection setup, and coverage requirements. Agent instructions live in AGENTS.md.
