OpenAPI ↔ Python. This is one compiler in a suite, all focussed on the same task: Compiler Driven Development (CDD).
Each compiler is written in its target language, is whitespace and comment sensitive, and has both an SDK and CLI.
The core philosophy of Compiler Driven Development (CDD) is synchronization without compromise. Where traditional generators silo your API boundaries into read-only files, this compiler natively merges changes into your codebase via a robust, [whitespace and comment aware] Abstract Syntax Tree (AST) driven parser & emitter. It bridges the gap between design and implementation, allowing you to seamlessly generate SDKs from a spec or extract a spec from existing code. By keeping your APIs, SDKs, and tests in continuous, automated alignment, it drastically improves both delivery speed and software reliability.
The CLI—at a minimum—has:
cdd-python-all --helpcdd-python-all --versioncdd-python-all from_openapi to_sdk_cli -i spec.jsoncdd-python-all from_openapi to_sdk -i spec.jsoncdd-python-all from_openapi to_server -i spec.jsoncdd-python-all to_openapi -f path/to/codecdd-python-all to_docs_json --no-imports --no-wrapping -i spec.jsoncdd-python-all serve_json_rpc --port 8080 --listen 0.0.0.0

The cdd-python-all compiler leverages a unified architecture to support various facets of API and code lifecycle management. For a deep dive into the compiler's design, see ARCHITECTURE.md.
- Compilation:
- OpenAPI →
Python: Generate idiomatic native models, network routes, client SDKs, and boilerplate directly from OpenAPI (.json/.yaml) specifications. Python→ OpenAPI: Statically parse existingPythonsource code and emit compliant OpenAPI specifications.
- OpenAPI →
- AST-Driven & Safe: Employs static analysis instead of unsafe dynamic execution or reflection, allowing it to safely parse and emit code even for incomplete or un-compilable project states.
- Seamless Sync: Keep your docs, tests, database, clients, and routing in perfect harmony. Update your code, and generate the docs; or update the docs, and generate the code.
Uncommon Features:
cdd-python-all supports standard CDD features.
