Pre-commit hook: file casing validation

This check validates the casing of Kibana resources (files and folders). It runs as part of the pre-commit hook and can also be run manually via the check file casing script.

Expected casing

• Default: All resources are expected to use snake_case.
• Package roots: Folder names of Kibana modules of type "package" are expected to use kebab-case. Package roots are the directories that contain a kibana.jsonc manifest with type !== 'plugin' (i.e. they are packages, not plugins).
• KEBAB_CASE_PATTERNS: The config.ts file defines a KEBAB_CASE_PATTERNS constant (glob patterns). Any path matching one of these patterns is expected to use kebab-case.

Kibana modules are identified by the presence of a kibana.jsonc manifest. The manifest’s type property indicates the kind of module: type === 'plugin' for plugins, and any other value (e.g. "package") for packages. Only package root directories get the kebab-case expectation; plugins do not.

Exclusions

Paths matching any of the IGNORE_PATTERNS in config.ts are excluded from the check. That list includes build artifacts, third-party conventions, and other paths where casing cannot or should not be enforced.

Configuration

• IGNORE_PATTERNS (config.ts): Glob patterns for paths to skip entirely.
• KEBAB_CASE_PATTERNS (config.ts): Glob patterns for paths that must use kebab-case instead of snake_case.
• exceptions.json: Paths that are known violations and are temporarily allowed (e.g. until migrated). Use --generate-exceptions when running the check to refresh this file from current violations.
