About:
hindent is a Haskell source code formatter that automatically re-indents and restructures code according to a consistent style. It enforces a standard layout, improving code readability and reducing style debates in teams. Its primary value is providing an opinionated, automated tool for maintaining clean and uniform Haskell codebases.

Key Features:

Automatic code re-indentation and restructuring
Configurable style options for team conventions
Command-line interface for easy integration into workflows
Preserves original semantics while formatting
Supports a wide range of Haskell language extensions

Use Cases:

Enforcing a consistent code style across a Haskell project before commits
Automatically cleaning up and standardizing legacy or inconsistently formatted code
Integrating into CI/CD pipelines to ensure style compliance

Alternatives:

stylish-haskell – Focuses more on import sorting and simple formatting, while hindent is more opinionated on overall code structure.
brittany – Another popular formatter; often compared for differences in layout algorithms and configurability.
