mellea.stdlib

The mellea standard library of components, sessions, and sampling strategies.

This package provides the high-level building blocks for writing generative programs with mellea. It contains ready-to-use Component types (Instruction, Message, Document, Intrinsic, SimpleComponent, and more), context implementations (ChatContext, SimpleContext), sampling strategies (rejection sampling, budget forcing), session management via MelleaSession, and the @mify decorator for turning ordinary Python objects into components. Import from the sub-packages — mellea.stdlib.components, mellea.stdlib.sampling, and mellea.stdlib.session — for day-to-day use.

Streaming chunking strategies (for use with streaming validation) are available at mellea.stdlib.chunking and re-exported here for convenience. The core streaming orchestration primitive :func:~mellea.stdlib.streaming.stream_with_chunking and its result type :class:~mellea.stdlib.streaming.StreamChunkingResult are also re-exported here, alongside the full :class:~mellea.stdlib.streaming.StreamEvent vocabulary for typed event observation.
