alphapulldown-input-parser

Reusable parser for AlphaPulldown-style fold specifications. Install it with:

pip install alphapulldown-input-parser

or, for local development:

pip install -e /path/to/alphapulldown-input-parser

The package exposes two helpers:

• parse_fold(...) – mirrors the historical AlphaPulldown helper and performs feature existence checks.
• expand_fold_specification(...) – expands a single fold string without raising if features are missing.

The parser is dependency-free and works across AlphaPulldown, the Snakemake pipeline, or any other tooling that consumes the same fold syntax.
