nomasystems/ndto

This system is an Erlang library that parses JSON Schema specifications (specifically Draft-04) and generates corresponding validation code. It provides a modular architecture for handling various schema types and enforces runtime data validation against defined constraints. The project includes a comprehensive test suite using property-based testing to ensure the accuracy of both the parsing and generation processes.

This change introduces the core ndto library, enabling users to parse JSON Schema specifications (specifically Draft-04) and generate Erlang validation modules. The update adds the \ndto\_parser\ interface and \ndto\_parser\_json\_schema\_draft\_04\ implementation for reading schemas, \ndto\_generator\ for producing validation code, and \ndto\_validation\ for runtime checks. It also updates the application version to 0.4.0 and adds \compiler\ and \syntax\_tools\ as dependencies.

src · high confidence

The NDTO generator implementation has been refactored to split validation logic for different JSON Schema types into separate, dedicated modules (such as ndto\_generator\_array, ndto\_generator\_object, ndto\_generator\_string, and ndto\_generator\_integer). Each module implements the ndto\_generator behavior to handle specific schema keywords (e.g., min/max constraints, pattern matching, or nested property validation), replacing the previous monolithic structure with a modular architecture that improves code organization and maintainability.

Added property-based tests for DTO validation logic; Added test configuration files for the test suite; Initial test suite for ndto validation and JSON Schema parsing.

This change introduces a CONTRIBUTING.md file to provide developers with guidelines for reporting bugs, requesting features, and submitting code changes, including branch naming conventions and commit message standards. It also updates the project's build configuration (rebar.config) to include new dependencies (ncalendar, gradualizer, rebar3\_ex\_doc) and test dependencies (nct\_util, triq), adds CI badges and documentation links to the README, and updates the .gitignore to exclude the doc/ directory.
