Component Details

This component is central to how pre-commit manages its operational parameters and the external code repositories it interacts with. It ensures that the application's behavior is consistent, validated, and efficiently handles the lifecycle of cached repositories.

Configuration Schema & Validation

Defines and validates the structure and content of the .pre-commit-config.yaml and manifest.yaml files. It includes checks for hook definitions, language types, and pre-commit version compatibility. It also handles the migration of deprecated stage names.

• pre_commit.clientlib (1:1)

YAML Parser

Provides robust functionality for loading and dumping YAML data, specifically tailored for pre-commit's configuration files. It handles various YAML-related operations, including safe loading and error handling during parsing.

Related Classes/Methods:

• pre_commit.yaml (1:1)

YAML Rewriter

Facilitates in-place modifications and updates to YAML files, particularly the .pre-commit-config.yaml. This is essential for operations like autoupdate or migrate-config, allowing pre-commit to programmatically adjust the user's configuration while preserving comments and formatting.

Related Classes/Methods:

• pre_commit.yaml_rewrite (1:1)

Repository Store

Manages the local cache of pre-commit repositories. This includes operations for initializing, cloning, and retrieving repositories, as well as garbage collection to manage disk space. It acts as a persistent storage mechanism for the cloned repositories.

Related Classes/Methods:

• pre_commit.store (1:1)

Repository Management

Encapsulates the logic for interacting with individual pre-commit repositories. This includes cloning, checking out specific revisions, and managing the repository's internal state and manifest. It bridges the gap between the abstract concept of a repository and its physical representation on disk.

Related Classes/Methods:

• pre_commit.repository (1:1)
