massRename

Command: massRename
Category: Mass Operations
Status: Production Ready

Description

Rename fields in bulk based on a CDS schema file. This command processes CAP CDS models and creates projection entities with renamed elements, supporting naming conventions like camelCase, snake_case, and case transformations across entire CDS schemas.

Use Cases

• Naming Convention Alignment: Convert field names to match project standards (camelCase, snake_case, etc.)
• Entity Prefixing: Add prefixes to all entities for namespace organization
• Case Normalization: Standardize case conventions across legacy or external schemas
• Field Aliasing: Create projection views with renamed fields for compatibility
• Schema Evolution: Generate new entity definitions with improved naming

Supported Case Formats

Format	Example	Use Case
camel	firstName, lastName	JavaScript, Node.js, CAP conventions
snake	first_name, last_name	Database conventions, Python
lower	firstname, lastname	Lowercase normalization
upper	FIRSTNAME, LASTNAME	Legacy systems, all-caps conventions
